Description
Technical Field
The invention relates to a steering bullet supply mechanism and an adaptive bullet supply tool thereof, which are specially designed for improving the bullet supply mode of a gun with a non-support structure.
Background
The choice and mounting of the magazine for a butt-free firearm has been structurally contradictory. Compared with a QBZ03 type automatic rifle with a supporting structure, the QBZ95 type automatic rifle with a domestic supporting structure has the advantages that the position of the QBZ95 type automatic rifle for installing a 30-shot magazine is determined, the shell throwing position of a shell throwing window is very close to the cheek of a shooter, the distance from a trigger to a shoulder supporting plate is increased, the height of a gun behind a handle is increased, and prone position hidden shooting is not facilitated. The 75 offset bullet drums that QBB95 type class machine gun was equipped with causes the gun focus to shift, need the hand of shooter to correct when holding the rifle, and the bullet drum weight is big moreover, and the structure is complicated, is not ideal and supplies the bullet utensil. In view of the above problems, the recently developed QBZ191 automatic rifle in China returns to a supporting structure, while the QJS161 class machine gun adopts a bullet feeding structure compatible with a magazine and a bullet train, but the reliability of the bullet train in battlefield dust and sediment is inferior to that of a bullet drum. Taking a QCW05 type submachine gun with a non-supporting structure as an example, in order to enhance the persistence of fire, a 50-row four-row magazine is adopted as a bullet feeding device. The inside of the box magazine is formed by combining two double-row single-feeding boxes, so that the probability of faults is increased; the four rows of magazines are too close to the small grip, which causes hand rest problems. As described above, even if the gun structure is selected differently, the contradiction between the requirement for the continuation of the fire power and the large-capacity ammunition supply still exists.
In order to solve the problems of the bullet supply device of the gun with the non-supporting structure, people at home and abroad have explored. In the journal of light weapon at 4 th 1999 in China, a paper of Liu Suqin and Yao Wu, namely a novel bullet supply tool-turning bullet drum, describes a bullet drum for realizing the turning bullet supply of a rifle with 5.8mm by using a plastic spiral channel, but is not popularized and applied. The P90 individual self-defence weapon in belgium abroad uses shorter bullet, and the scheme of steering bullet supply is to supply bullet by using an upper magazine, and 90-degree steering bullet supply is realized by pushing the bullet to fall into the inclined plane device from top to bottom. However, the friction force generated between the front end and the rear end of the bullet in the structure and the steering inclined plane is opposite, the friction resistance is increased in a closed space, and the reliability in battlefield dust and sediment is doubtful. Whether the steering bullet drum can be popularized or not is also checked whether the reliability of the steering bullet supply structure meets the use requirement.
Disclosure of Invention
Basic principle:
the invention discloses a steering bullet supply mechanism and an adaptive bullet supply tool thereof. The basic principle is that steering is realized by utilizing the guiding effect generated by two parallel inclined planes with opposite left and right directions on the bullet. The basic characteristic is that the bottom edge of the thin wall structure at two sides of the single-row small magazine is cut into inclined planes with opposite left and right directions to form a steering inclined plane 1 and a steering inclined plane 2; the single-row small magazine is arranged in the middle and vertically on a bullet outlet of the adaptive bullet supplying tool, and the bullet in the steering process is limited and protected by a protective cover with an arc surface at the periphery of the steering inclined plane 1 and the steering inclined plane 2; when the bullet is pushed out of the bullet outlet by the bullet feeding tool, the front end and the rear end of the bullet body deflect along the steering inclined plane 1 and the steering inclined plane 2 and enter the single-row small magazine to form a steering bullet feeding mechanism.
The steering bullet supply mechanism has the advantages that the steering inclined plane 1 and the steering inclined plane 2 are provided by thin-wall structures on two sides of a single-row small magazine, the contact area with a bullet body is small, the generated friction resistance is also small, the bullet is in an open state in the steering process, and the capability of overcoming battlefield dust and sediment is relatively strong. The steering can be realized as long as the front and rear ends of the bullet body enter the control ranges of the steering inclined planes 1 and the steering inclined planes 2, and the steering angle is determined by the installation angles between the steering inclined planes 1 and 2 of the bottom edges of the two sides of the single-row small magazine and the bullet outlet of the bullet feeding device. Compared with the existing steering scheme, the steering bullet supply mechanism overcomes the defect of high resistance caused by the fact that bullets roll along inclined planes in a plastic spiral channel, and improves the reliability of the steering mechanism; and the structure is simple, and the manufacturing is easy.
The bullet feeding device adapted to the bullet feeding mechanism comprises a bullet drum or a bullet box. When the bullet drum is selected as an adaptive bullet feeding tool, a small bullet box of an adaptive bullet box well above the bullet drum is removed, the external dimension of a single-row small bullet box above a protection cover of a steering bullet feeding mechanism is matched with the size of a bullet box well of an adaptive gun, and steering bullet feeding can be realized by aligning a steering inclined plane 1 and a steering inclined plane 2 which are formed by the bottom edges of two sides of the single-row small bullet box in the steering bullet feeding mechanism and vertically installing the steering inclined plane above the bullet outlet position of the bullet drum. The offset drum of the QBB95 type working machine gun can be modified into a steering drum according to the principle.
When the adaptive bullet feeding tool of the steering bullet feeding mechanism selects the double-row double-feeding bullet box with large capacity, in order to exert the advantages of the steering bullet feeding mechanism, the design that the steering bullet feeding mechanism is separated from the double-row double-feeding bullet box is adopted. Firstly, flatly installing a magazine well in a rear upper part Fang Jixia of a small grip to form a rear insertion type magazine well; the steering bullet supply mechanism is arranged above the rear-inserted magazine well, the double-row double-feed magazine is arranged in a flat way backwards along the direction of the gun stock, and the length of the double-row double-feed magazine is determined according to the allowable installation length of the gun stock; thus, the high capacity double row double entry magazine no longer occupies the gun height. Secondly, the rear-inserted magazine well cannot directly use the traditional double-row double-inlet magazine, the ejection outlet of the double-row double-inlet magazine needs to be transformed into a single-side ejection holding structure, and the single-side ejection holding structure is used for locking the bullet inside the double-row double-inlet magazine; the two sides of the unilateral bullet holding opening are slotted, and the missile inclined plane is correspondingly inserted into the unilateral bullet holding opening along the slotting position, so that the bullets are separated from the constraint of the unilateral bullet holding opening, double rows of double inlets are changed into single rows of bullets, and then enter the steering bullet feeding mechanism along the missile inclined plane, thereby realizing double rows of single inlets steering bullet feeding.
The bullet feeding structure of the submachine gun with the supporting-free structure can be improved according to the principle, and the gun support can be directly replaced by a double-row double-feeding magazine with large capacity. Not only can reduce the height of the whole gun, but also is beneficial to reducing the hook.
The concrete structure is as follows:
the steering bullet supply mechanism is characterized in that a single-row small magazine is centered and vertically arranged above the bullet outlet of the bullet supply device, and a bullet holding opening is arranged above the single-row small magazine; when the bullet outlet of the bullet supplying device is set to be in a horizontal state and the bullet heads of the bullets are directed to the right and the bullets need to turn anticlockwise to lead the bullet heads to be directed to the right, the bottom edge of the right side of the single-row small bullet box is arranged above the projection position of the bullet outlet of the bullet supplying device, an inclined plane with the height larger than the diameter of the bullets is opened from back to front and hollowed forwards to form a turning inclined plane 1, the bottom edge of the left side of the single-row small bullet box is arranged above the projection position of the bullet outlet of the bullet supplying device, an inclined plane with the height larger than the diameter of the bullets is opened from front to back and hollowed backwards to form a turning inclined plane 2, thus, a pair of parallel turning inclined planes 1 and turning inclined planes 2 with opposite left and right directions are formed on the bottom edges of the two sides of the bullet boxes, and the arc surfaces provided by the protection covers are arranged at the peripheries of the turning inclined planes 1 and the turning inclined planes 2 to provide limit protection for the bullets in the turning process; when the bullet is pushed to the control range of the steering inclined plane 1 and the steering inclined plane 2 by the adaptive bullet feeding tool, the front end and the rear end of the bullet body are guided by the parallel steering inclined plane 1 and the steering inclined plane 2 which are opposite in left and right to enter the hollowed-out position for barrier-free rotation, and when the bullet body rotates to the position parallel to the steering inclined plane 1 and the steering inclined plane 2, the control of the steering inclined plane 1 and the steering inclined plane 2 is eliminated, and the bullet body enters the single-row small magazine until the locking position of the bullet holding opening at the top end of the single-row small magazine is reached, so that the whole steering process is completed.
The bullet supplying mechanism comprises a bullet drum or a bullet box.
When the adapted bullet feeding device selects a bullet drum, the bullet feeding device is characterized in that the external dimension of a single-row small magazine above a bullet feeding mechanism protecting cover is matched with the magazine well dimension of an adaptive gun, a steering inclined plane 1 and a steering inclined plane 2 which are formed by the bottom edges of two sides of the single-row small magazine in the bullet feeding mechanism are aligned and vertically arranged above the bullet outlet position of the bullet drum, so that the bullet feeding is realized, and the simple and practical bullet feeding device is formed.
When the adapted bullet feeding device selects the bullet box, the design that the bullet feeding mechanism is separated from the bullet box is adopted. The double-row double-feed magazine is characterized in that a rear-insertion magazine well is adopted, the improved double-row double-feed magazine is arranged in a flat mode, and a steering bullet supply mechanism is arranged above the rear-insertion magazine well. The rear-inserted magazine well is positioned in the interior of the case above the rear part of the small grip of the gun, and is formed by installing a partition plate on the case according to the flat installation height of the double-row double-inlet magazine by utilizing the bottom and two sides of the case; a missile inclined plane for guiding the bullets to ascend is arranged in the rear-inserted magazine well. The rear plug magazine well allows for flat mounting of the modified double row double entry magazine in accordance with the length of the stock to take advantage of this configuration to accommodate high capacity magazines.
The double-row double-feeding magazine adopts a single-side spring holding opening structure. According to the structure, two bullets are pressed in one time by two hands, namely, one bullet is pressed in one side of a plane to be kept in a pressed state, and then a second bullet is pressed in one side of a single-side bullet holding opening, so that the restriction on the bullets in the magazine can be realized; the two sides of the single-side spring holding opening are slotted, and the slotting positions of the two sides correspond to missile inclined planes arranged in the rear-inserted magazine well. The missile inclined plane is provided by a U-shaped structure arranged at the bottom of the case, and the rear edges of the thin-wall structures at two sides of the missile inclined plane form a double-inclined plane structure; the missile inclined plane on the left side of the U-shaped structure and the steering inclined plane 2 on the upper side form an integrated guide structure, and the turning part of the missile inclined plane is made into a smooth arc line so as to avoid the jam fault caused by overlarge turning angle. When the double-row double-feed magazine is inserted into the rear-insertion magazine well, the missile inclined plane enters the unilateral missile holding opening from the slotting positions at the two sides of the unilateral missile holding opening, so that the bullets are forced to break away from the constraint of the unilateral missile holding opening, and the bullets are released along the missile inclined plane to enter the control ranges of the steering inclined plane 1 and the steering inclined plane 2 arranged in the steering missile supply mechanism; when the bullet rotates to a position parallel to the steering inclined plane 1 and the steering inclined plane 2, the bullet enters the single-row small magazine, and then is locked by the holding opening at the top end of the single-row small magazine. When the bullet pushing and protruding bamboo shoots of the gun machine pass through the bullet holding opening at the top end of the bullet feeding mechanism, the bullet is pushed into the bullet chamber of the gun barrel, so that a vacancy appears in the small bullet box, and the following bullet is pushed by the pushing spring to finish steering through the steering inclined plane 1 and the steering inclined plane 2 to enter the single-row small bullet box, and is locked by the bullet holding opening at the top end, so that the continuous bullet feeding function is realized.
When the double-row double-feeding magazine is in a flat installation state, the front end of the bottom is centrally provided with a locking protruding bamboo shoot, and the locking protruding bamboo shoot corresponds to the front end of a magazine clamping bamboo shoot at the bottom end of a rear-insertion magazine well.
The magazine clamping bamboo shoot is an L-shaped lever structure for locking the magazine locking bamboo shoot. The bottom of back plug-in magazine well constitutes the window along vertical fretwork according to the width of magazine shutting salient bamboo shoot, and the lower extreme installation magazine card bamboo shoot base of window position has the installation shaft hole of magazine card bamboo shoot on the magazine card bamboo shoot base, and the centre of magazine card bamboo shoot is installed in the installation shaft hole with the installation shaft, and the front end of magazine card bamboo shoot is supported with the moment of torsion spring of installing around the installation shaft for the front end of magazine card bamboo shoot gets into the magazine well along the window, and the rear end of magazine card bamboo shoot is located the outside of window, constitutes a lever structure that can be driven around the installation shaft by the rear end of magazine card bamboo shoot. After the locking protruding bamboo shoots of the double-row double-inlet magazine are aligned with the windows at the bottom side of the rear-insertion magazine and are inserted in place, the front ends of the clamping bamboo shoots of the magazine are sprung up to prop against the locking protruding bamboo shoots at the bottom ends of the double-row double-inlet magazine. When the magazine is released, the rear end of the magazine clamping bamboo shoot is pressed backwards from the outside of the bottom of the rear-insertion magazine well, so that the front end of the magazine clamping bamboo shoot falls off the locking protruding bamboo shoot, and the double-row double-inlet magazine can slide or be pulled out from the rear-insertion magazine well.
The bullet steering and feeding mechanism and the bullet feeding device are characterized in that when the conditions that the front end and the rear end of a bullet are positioned in the control range of a steering inclined plane 1 and a steering inclined plane 2 formed by the bottom edges of a single-row small bullet box in the bullet steering and feeding mechanism are met, the steering angle of the bullet comprises, but is not limited to, a vertical angle, and the steering angle of the bullet is finally determined by the installation angle between the steering inclined plane 1 and the steering inclined plane 2 formed by the bottom edges of the single-row small bullet box and the bullet outlet of the bullet feeding device below; when the drum of the 95 class machine gun is modified, the steering angle is allowed to be adjusted to improve the man-machine efficiency.
The steering bullet supply mechanism and the adaptive bullet supply tool thereof are characterized in that when the steering bullet supply mechanism is used for adapting a rifle magazine with larger size, the rear plug-in magazine well and the steering bullet supply mechanism above are integrally rotated for 180 degrees, and then the bullet heads of the double-row double-feed bullets inserted into the magazine well are pointed to the right as default states, so that the front plug-in magazine well and the steering bullet supply mechanism can be obtained. The front-inserted magazine well and the steering bullet supply mechanism are arranged in front of the trigger guard ring, so that the gun is suitable for improving a traditional gun with a supporting structure, and a double-row double-feed magazine with a larger size for loading rifle bullets can be used, thereby being beneficial to reducing the height of the gun and reducing the hook.
The present invention can produce the following advantageous effects. First, the simplest straightforward application of the steering feed mechanism is to retrofit the offset drum of a QBB95 class gun. Although a new model QJS161 type working machine gun has been developed, the holding capacity of the QBB95 type working machine gun is large, and the QBB95 type working machine gun can better exert waste heat after being modified.
And secondly to develop new adapted firearms. Taking a submachine gun with a relatively simple structure as an example, referring to the technical index of the 05 submachine gun, the rear plug-in magazine well can be adapted to 50 double-row double-inlet long magazines for shooting 5.8mm pistol, or to 9mm double-row double-inlet long magazines for shooting pistol, and the failure rate is lower than that of four rows of magazines. The use of the post-insertion magazine well not only can reduce the height of the whole gun, but also is beneficial to reducing the hooking. The problem that the hand is put to four rows of magazines of 05 submachine gun is solved, simultaneously make the throwing shell mouth advance, the man-machine efficiency is improved, can better accomplish infantry tactics action.
The working process comprises the following steps:
taking the double-row double-feed magazine as an example, when the double-row double-feed magazine is inserted into the rear-insertion magazine well, the missile inclined plane in the rear-insertion magazine well enters the grooves at the two sides of the unilateral missile holding opening of the double-row double-feed magazine, the bullets are released along the missile inclined plane to enter the control ranges of the steering inclined plane 1 and the steering inclined plane 2, and meanwhile, the double-row double-feed magazine is locked by the magazine clamping shoots.
The bullet is pushed by the push springs of the double-row double-feed magazine, the front end and the rear end of the bullet body are guided by the steering inclined plane 1 and the steering inclined plane 2 to finish steering and enter the single-row small magazine, and the bullet body is locked by the holding opening at the top end of the single-row small magazine.
When the bullet is pushed out of the bullet holding opening by the bullet projecting shoot by the gun machine and a vacancy appears in the single-row small magazine, the bullets in the lower double-row double-feeding magazine are continuously pushed to the control ranges of the steering inclined plane 1 and the steering inclined plane 2 under the driving of the push spring, so that a continuous steering bullet supply process is formed.
