All other embodiments, which can be made by one of ordinary skill in the art without the need for inventive faculty, are within the scope of the present disclosure, based on the described embodiments of the present disclosure.
Unless defined otherwise, technical or scientific terms used in this disclosure should be given the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure belongs. The use of the terms "comprising" or "includes" and the like in this disclosure is intended to cover an element or article listed after that term and equivalents thereof without precluding other elements or articles. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may also include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.
As shown in fig. 1 to 25, the multi-parameter adjustable wheelchair main body provided by the invention comprises a wheelchair main body 1, wherein the wheelchair main body comprises a skeleton frame 15, a back rest 12 and a foot pedal 14, and an existing wheelchair structure is improved, so that the wheelchair main body is suitable for implementation of an embodiment of the invention, according to fig. 1 to 4, the skeleton frame 15 is designed into two independent side skeletons by an original integral structure, and is symmetrically distributed on two sides of the outer wall of a template combination seat 2 along the X-axis direction of a cushion plate surface of the wheelchair main body 1, the back rest 12 is formed by independent arc plates which are mutually inserted, and the two arc plates are respectively arranged on the outer wall of one side adjacent to the two skeleton frames 15. That is, when the two frame frames 15 move in the Y-axis direction in synchronization with the die plate combining base 2, (the frame frames 15 are mounted on the combining plate II 22) and the plate diameter of the back rest 12 formed by the two arc plates increases with the distance between the two frame frames 15.
Further, in order to ensure the depending stability of the backrest 12, as can be seen from fig. 3, the two skeleton frames 15 are symmetrically provided with a short beam 8 for being matched with the backrest 12 to extend and synchronously extend, the short beam 8 is composed of a scale tube 81 and a marking tube 82, one end of the scale tube 81 is provided with scales, the radius of the end provided with the scales is smaller than that of the end without the scales, one end of the marking tube 82 is of a hollow structure, an observation window is arranged on the outer wall of the hollow structure, one end of the scale tube 81 provided with the scales is inserted into one end of the marking tube 82 provided with the observation window, that is, when the two skeleton frames 15 keep deviating from movement, the short beam 8 and the backrest 12 synchronously extend, and current extending data are acquired through the observation window. (because of the split design of the back rest 12, the surface of the back rest 12 is covered with a nylon cover)
Furthermore, as can be seen from fig. 4, the base 4 is disposed under the cushion plate of the wheelchair main body 1, the outer walls of the two frame frames 15 are pivotally connected with the curved bars 42, the universal balls at the tail ends of the two curved bars 42 are symmetrically connected in the ball grooves on the outer wall of one side of the base 4, the outer walls of the two frame frames 15, which are close to the back rest 12, are respectively provided with a side wing 41, the side wings 41 are slidably connected to the top of the base 4, which is far away from the outer wall of one side of the curved bars 42, and the shaft lever of the rear wheel of the wheelchair main body 1 is mounted on the outer wall of the base 4, which is far away from one side of the curved bars 42.
In order to ensure the stability of the whole wheelchair after being disassembled, the connected base 4 is utilized to ensure the whole wheelchair to be integrally ductile when the two framework frames 15 keep deviating from each other.
In addition, in order to fit a patient with a longer leg, the foot rest 14 and the skeleton frames 15 on both sides are in a plug-in design, and the foot rest 14 is also in a plug-in design (the rod body a and the rod body b plugged in one end of the rod body a are in a u-shaped structure), so that the foot rest 14 can extend or shrink along with the movement of the skeleton frames 15 when the foot rest is kept away from the body, and after the contraction is completed, the rod body b needs to be fixed by using the fixing screws on the rod body a so that the whole foot rest 14 forms a stable structure.
In addition, the handrail 11 is also in a plug-in type design, and can be manually adjusted through screws on the two skeleton frames 15 according to the requirement, so that the height of the current guardian can be adapted.
