Description

A replaceable fishing rod handle

technical field

The invention relates to fishing gear, in particular to a fishing rod component, more specifically, to a replaceable fishing rod handle.

Background technique

For the convenience of carrying, the vast majority of existing fishing rods are telescopic structures, and their effective fishing range is mainly determined by the unfolding distance of each rod joint that is grouped together in sequence. In order to make the same fishing rod adapt to different fishing environments such as rivers, ponds, and reservoirs, there is an interchangeable fishing rod on the market, that is, the fishing distance of the fishing rod can be adjusted according to needs. For example, the outline size of the penultimate section, the penultimate section, the penultimate section, etc.) Prepare multiple handles corresponding to it, and remove the tail section of the original fishing rod according to the fishing range to form a new length Fishing rod, assemble the handle corresponding to it on the tail section of the re-length fishing rod (maybe the penultimate section, penultimate section, etc. of the original fishing rod). For example, for a fishing rod with an original length of 5.4 meters, when the fishing distance is only 4.5 meters, the tail section of the 5.4-meter fishing rod is removed to form a 4.5-meter fishing rod. At this time, the handle on the removed tail section is with it. Select a handle corresponding to the contour size of the tail rod section of the 4.5-meter fishing rod from the spare handles to be carried again, so as to facilitate the hand-holding operation of the 4.5-meter fishing rod. This kind of interchangeable fishing rod needs to prepare a plurality of special handles of corresponding size, and each handle cannot be used universally, which not only increases the manufacturing cost of the fishing rod and affects market competition, but also the carrying and management of this multi-handle is very troublesome. Once a handle is lost, It will affect the comfort of the grip of the fishing rod after the fishing distance is adjusted, and the usability is poor.

Chinese patent literature discloses a "new type of change handle" (publication number: CN 201029378, publication date: March 5, 2008). The method is set with a nut to tighten the handle to the fishing rod. Although it can adjust the length of the fishing rod to a certain extent, the tightening degree of the handle to the fishing rod depends on the size of the inner diameter of the nut, and its versatility and reliability are relatively limited. Poor sex.

detailed description

Example 1

Referring to Fig. 1 and Fig. 2: the present invention is a fishing rod handle that can be replaced according to actual needs, including a handle body 4, which has an axial direction and a diameter slightly larger than that of the fishing rod 5 (referring to the maximum diameter of the tail end of the entire fishing rod). The piercing hole of the outer diameter of the pole joint), that is, the handle body 4 is a hollow structure, and when it is assembled on the fishing rod 5 for use, the fishing rod 5 is axially pierced in the handle body 4 through the piercing hole.

The above-mentioned handle body 4 is an integral structure, and the diameters at both ends of the piercing hole of the handle body 4 are larger than the diameter of the middle part, that is, the two ends of the piercing hole of the handle body 4 respectively form a stepped structure, and the piercing hole of the handle body 4 at the step structure is formed. The locking space is provided; in the aforementioned two locking spaces, there are respectively placed flexible elastic rings formed of rubber material, that is, the first elastic ring 3 in the front locking space and the second elastic ring 8 in the rear locking space, The two elastic rings respectively have a piercing hole slightly larger than the outer diameter of the fishing rod 5, and the elastic ring is mounted on the outer wall of the fishing rod 5 through its own piercing hole; the circumference of the first elastic ring 3 and the second elastic ring 8 Extrusion gaps are reserved between the outer walls and the circumferential walls of the locking space on the handle body 4 where they are respectively located. The outer walls of the handle body 4 corresponding to the aforementioned two locking spaces are respectively provided with connecting threads, and the outer walls of the handle body 4 are respectively threadedly connected with locking nuts, that is, the first locking nut 1 at the front end and the rear locking nut 1. The second locking nut 6 at the end, the first locking nut 1 is worn on the fishing rod 5 through the piercing hole in the center of itself, that is, the fishing rod 5 passes through the first locking nut 1 and extends into the handle body 4; The inner holes of the first lock nut 1 and the second lock nut 6 are fitted with rolling balls respectively (it can also be a sliding fit without balls, but the assembly effect is not as good as that of balls). The sleeve, that is, the lock nut and the squeeze sleeve are of a split structure, the first lock nut 1 is the first squeeze sleeve 2, and the second lock nut 6 is the second squeeze sleeve 7, It is required that the extrusion sleeve in the locking nut corresponds to the outer edge of the elastic ring. At the same time, in order to prevent the two extrusion sleeves from swinging freely during the assembly process, it is required that the outer diameters of the two extrusion sleeves are respectively in line with the lock nut. The inner diameter of the tight space should match accordingly. In this case, the position of the extrusion sleeve should be between the outer edge of the elastic ring and the wall of the locking space. In order to increase the locking force of the elastic ring, it is better to make the end surface of the extrusion sleeve and the end surface of the elastic ring There is a large overlapping surface between them. The present invention moves through the axial assembly movement of the lock nut (that is, the first lock nut 1 and the second lock nut 6 ) on the handle body 4 by tightening or loosening, so that the lock nut is squeezed The sleeve (namely the first extrusion sleeve 2, the second extrusion sleeve 7) abuts and squeezes or releases the elastic ring (namely the first elastic ring 3, the second elastic ring 8) in the corresponding locking space , the locking nut transforms the elastic ring into radial deformation and contraction through the axial extrusion of the elastic ring by the extrusion sleeve, and the radially contracted elastic ring tightens the fishing rod 5 worn in the handle body 4, so that the handle The front and rear ends of the fishing rod are all tightened and locked tightly with the fishing rod 5. Since the extrusion sleeve on the above-mentioned lock nut is assembled on the lock nut by ball rolling, it can be used during the extrusion process of the elastic ring Effectively reduce frictional resistance, avoid circumferential twisting and deformation of the elastic ring, and prolong the service life of the elastic ring.

In order to make the extrusion sleeve on the locking nut squeeze the elastic ring in the locking space smoothly and well, the inner edge of the extrusion sleeve on the locking nut facing the elastic ring has a tapered structure (that is, the inner The outer edge of the end surface of the elastic ring facing the extrusion sleeve is also a cone structure (that is, the outer cone shape), that is, the extrusion sleeve on the locking nut and the elastic ring are matched with a cone structure. Based on the aforementioned structural design, it is also possible to design only the inner edge of the end surface of the extrusion sleeve on the locking nut facing the elastic ring as a tapered structure, and the right-angled angular structure of the end surface of the elastic ring facing the extrusion sleeve remains unchanged; or , only the outer edge of the end face of the elastic ring facing the lock nut extrusion sleeve is designed as a tapered structure, and the right-angled angular structure of the end face inner edge of the end face of the lock nut extrusion sleeve facing the elastic ring remains unchanged.

In order to make the elastic ring have a good radial shrinkage deformation, the elastic ring is designed as a star structure, that is, the elastic ring has a basic annular body, and a plurality of radially protruding wings are arranged on the outer periphery of the annular body (for contact with the extrusion sleeve on the lock nut), the number of these wings is reasonably determined according to actual use, as long as there are at least three wings, radial shrinkage deformation due to extrusion can occur. Besides the star structure, the elastic ring can also be other. For example, as shown in FIG. 3 , a plurality of wings are connected end to end to form a closed integral structure, and their inner ends form a discontinuous or continuous ring.

In addition to forming mutually independent locking spaces at the front and rear ends of the handle body, the present invention can also form locking spaces only at the front end or rear end of the handle body; Design the piercing hole on the handle body as an axial blind hole or through-hole structure; when only a locking space is formed at the tail end of the handle body, then the piercing hole on the handle body must be an axial through-hole structure . This kind of structure that only tightens the rod section of the set fishing rod at the front end or tail end of the handle, although it can be tightened and assembled or loosened with the fishing rod according to the needs, realizes the purpose of the present invention, but relatively speaking, the tightening The force is slightly weaker, and the force of a fulcrum is easy to cause the fishing rod to break under the action of external force.

Example 2

Referring to Fig. 4: other structures of this embodiment are the same as those of Embodiment 1, the difference is that the handle body 4 is a split structure, and the handle body 4 of the split structure is mainly composed of an outer sleeve 41 and an inner sleeve Sleeve 42, that is, the outer sleeve 41 has an axial hole that is slightly larger than the inner sleeve 42, and the length of the outer sleeve 41 is longer than the inner sleeve 42, and the inner sleeve 42 is worn on the outer sleeve 41. Inside, on the inner sleeve 42, there are axial, fishing rod 5 piercing holes, so that the outer sleeve 41 at the end of the inner sleeve 42 forms a locking space, and the outer wall of the outer sleeve 41 corresponding to the locking space Provided with threads for attachment to cage nuts.

Correspondingly, a first locking nut 1, a first extrusion sleeve 2, and a first elastic ring 3 are installed on the front locking space of the handle body 4, and a second locking nut is installed on the rear locking space of the handle body 4. Two locking nuts 6, a second extrusion sleeve 7, and a second elastic ring 8.

Through this combined structure of the handle body 4, when one end is locked or released, the other end can be locked or released simultaneously, thereby greatly improving the convenience of the fishing rod changing operation.

Example 3

Referring to Fig. 5: the other structure of this embodiment is the same as that of embodiment 2, the difference is that: the inner wall of the outer sleeve 41 corresponding to the locking space on the handle body 4 is provided with threads for connecting lock nuts and lock nuts. The cap is installed in the locking space of the handle body 4 (that is, the outer peripheral wall of the lock nut is provided with a connecting thread), and the extrusion sleeve is correspondingly assembled on the end of the lock nut through the ball (that is, when assembling, first squeeze The compression set is inserted into the locking space, and then squeezed by the locking nut).

Correspondingly, a first locking nut 1, a first extrusion sleeve 2, and a first elastic ring 3 are installed on the front locking space of the handle body 4, and a second locking nut is installed on the rear locking space of the handle body 4. Two locking nuts 6, a second extrusion sleeve 7, and a second elastic ring 8.

The structure of this embodiment effectively improves the comfort of the outer surface of the handle on the premise of ensuring reliable tightening and convenient operation, and has a good grip feeling.

Example 4

See Fig. 6: Other structures of this embodiment are the same as Embodiment 1, the difference is that: the inner wall of the locking space of the handle body 4 is provided with threads for connecting the locking nut, and the outer wall of the locking nut is provided with connecting threads And the locking nut and the extrusion sleeve are integrated, that is, only the first locking nut 1 and the first elastic ring 3 need be installed in the locking space at the front end of the handle body 4, and only the second elastic ring 3 needs to be installed in the locking space at the rear end. lock nut 6 and second elastic ring 8 . This structure with the locking nut itself as the extrusion sleeve can achieve the purpose of the present invention, but this structure generally has the following problems. The tightening and rotation of the locking nut on the handle body 4 will cause The elastic rings abutted together are rotated circumferentially under the action of frictional force, and along with the axial feed of the locking nut, the elastic rings will shrink and deform radially to tighten the fishing rod 5 in the handle body 4, and then As the radial clamping force increases, the elastic ring may be twisted and deformed in the circumferential direction, thereby affecting its service life. This problem in this embodiment can be solved by injecting lubricant (non-corrosive liquid including water).

Example 5

Referring to FIG. 7 , other structures of this embodiment are the same as those of Embodiment 3, except that the locking nut and the extrusion sleeve are integrated. That is, the handle body 4 is mainly composed of an outer sleeve 41 and an inner sleeve 42 that are combined together in a suit, and the inner wall of the outer sleeve 41 corresponding to the locking space on the handle body 4 is provided with a screw thread that is connected to a locking nut. The outer peripheral wall of the nut is provided with connecting threads. Only the first locking nut 1 and the first elastic ring 3 need be installed in the locking space at the front end of the handle body 4, and only the second locking nut 6 and the second elastic ring 8 need be installed in the locking space at the rear end.

The structure of this embodiment is actually a synthesis of Embodiment 3 and Embodiment 4 without conflicts.
