[0025] This application provides a novel folding wheelchair that effectively solves the problem that traditional folding wheelchairs have fixed handle heights, which cannot meet the needs of users of different heights, resulting in strenuous pushing and inconvenient use. The novel folding wheelchair features an adjustable handle height design, which can meet the comfort needs of users of different heights, making pushing more effortless and convenient. It also improves the accuracy and stability of pushing, thus providing users with a smoother movement experience. In addition, the wheelchair can be folded and stored for easy use through the design of the folding components.
[0026] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that in the actual use of traditional new folding wheelchairs, the handle height of the wheelchair is fixed, which cannot meet the needs of pushers of different heights, resulting in a laborious pushing process and inconvenient use. The overall idea is as follows:
[0027] To address the problems existing in the prior art, this utility model provides a novel folding wheelchair, comprising frames 1 distributed on the left and right sides, each frame 1 equipped with wheels 11, and each frame 1 with a footrest 12 on its front side. A seat cushion 2 is disposed between the two frames 1, and a folding assembly is disposed between the two frames 1. The folding assembly includes two intersecting folding rods 3, each folding rod 3 having its two ends hinged to the two frames 1 respectively. Uprights 5 are fixedly installed on each of the two frames 1, and cushions 4 are disposed on the two uprights 5. A slide cylinder 6 is fixedly installed at the upper end of each upright 5, and a slide groove is formed on the surface of each slide cylinder 6. A handle 7 is slidably inserted into each slide groove. A locking hole 61 is equidistantly formed on the surface of each slide cylinder 6, and a locking assembly is provided on each handle 7. The locking assembly includes a locking ball 8 adapted to the locking hole 61, and each locking hole 61 is distributed along the axial direction of the slide cylinder 6. A groove is formed on the surface of each handle 7, and each locking ball 8 slides in the groove. Each locking ball 8 has a spring 82 fixedly connected to its end. Each locking ball 8 is fixedly connected to the inner wall of the groove through the spring 82. Each locking ball 8 has a protruding post 81 fixedly connected to its end. Each spring 82 is sleeved on the protruding post 81. Each locking ball 8 is locked in the locking hole 61. When the wheelchair is needed, the folded wheelchair is unfolded. The two frames 1 are opened to a suitable position by the folding rods 3 which are arranged in a cross pattern and are hinged to the frame 1 at both ends, providing stable support for the user. The patient sits on the seat cushion 2 and leans against the backrest cushion 4. When someone pushes the wheelchair, the height of the handle 7 can be adjusted according to the actual pushing needs. When adjusting the height, the user presses the locking ball 8 to retract the locking ball 8 into the groove. At this time, the handle 7 is not blocked by the limit and can move vertically. When the handle 7 moves to the appropriate position, the elastic reset action of the spring 82 makes the locking ball 8 reset and re-lock into the corresponding locking hole 61, completing the limit locking.
[0028] Each handle 7 is equipped with an anti-slip sleeve 71, and the outer surface of each anti-slip sleeve 71 is provided with anti-slip texture, which increases the friction when the pusher grips the handle 7 and improves the safety of pushing.
[0029] The part of the handle 7 that slides inside the slide cylinder 6 has a flat design, which is used for sliding limit. The flat design of the part of the handle 7 that slides inside the slide cylinder 6 can effectively prevent the handle 7 from rotating during the sliding process, thus playing the role of sliding limit.
[0030] Working principle:
[0031] When the wheelchair is needed, the folded wheelchair is unfolded. The two frames 1 are opened to a suitable position by the folding rods 3, which are cross-shaped and hinged to the frame 1 at both ends, providing stable support for the user. The patient sits on the seat cushion 2 and leans against the backrest cushion 4. When someone pushes the wheelchair, the height of the handle 7 can be adjusted according to the actual pushing needs. When adjusting the height, the user presses the locking ball 8, which retracts into the groove. At this time, the handle 7 is not blocked by the limit and can move vertically. When the handle 7 moves to the appropriate position, the elastic reset action of the spring 82 causes the locking ball 8 to reset and re-lock into the corresponding locking hole 61, completing the limit locking. The part of the handle 7 that slides in the slide cylinder 6 has a flat design, which can effectively prevent the handle 7 from rotating during the sliding process and play a role in sliding limit.
[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
