Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] This utility model embodiment provides a novel wheelchair assembly structure, such as Figures 1-4 As shown, the wheelchair includes two wheelchair frames 1, each with armrests 2, a fixing rod 6, a seat 7, and a backrest 8. The lower ends of the opposite sides of the two wheelchair frames 1 are respectively provided with an insertion tube 3 and a sleeve 4. The sleeve 4 is hollow. One end of the insertion tube 3 and the sleeve 4 is fixed to the wheelchair frame 1, and the other end has a through hole 5 of the same size. The fixing rod 6 passes through the through hole 5. A fixing strip 9 is located in the middle of the opposite sides of the wheelchair frame 1. A dovetail groove 10 is formed on the fixing strip 9. A dovetail block 71 is provided on the lower end of the seat 7. The dovetail block 71 is slidably connected to the dovetail groove 10. A horizontal groove 72 is formed on the seat 7, and the backrest 8 passes through the horizontal groove 72.

[0021] Reference Appendix Figure 1The back panel 8 has a recess 81 at its lower end, with an insert 82 inside. A slot 61 is provided on the fixing rod 6, and an arc-shaped block 62 is fixed to the tail end of the fixing rod 6. A vertical groove 84 is provided on the back panel 8, with a diameter larger than that of the fixing rod 6. To fix the back panel 8, first separate the two wheelchair frames 1, insert the insert tube 3 into the sleeve 4, and align the through hole 5 on the insert tube 3 and sleeve 4. Pass the fixing rod 6 through the through hole 5 to complete the initial fixation of the wheelchair frame 1. Then, slide the dovetail block 71 into the dovetail groove 10. After the dovetail block 71 is fully inserted, insert the lower narrow part of the back panel 8 into the horizontal groove 72, while simultaneously inserting the insert 82 into the slot 61, thus fixing the back panel 8 and the fixing rod 6 together.

[0022] Reference Appendix Figure 1 A vertical fixing plate 12 is provided on one side of the fixing strip 9, and a dovetail groove 13 is provided on the vertical fixing plate 12. Arc-shaped notches 83 are provided on both sides of the back plate 8, and the size of the arc-shaped notches 83 is larger than the size of the sleeve 4. The back plate 8 is wider at the top and narrower at the bottom. The narrower part of the back plate 8 passes through the transverse groove 72, and the wider part of the back plate 8 rests against the seat plate 7. Both the wide and narrow parts of the back plate 8 have arc-shaped notches 83. When retracting, the dovetail block 71 on the seat plate 7 is inserted into the dovetail groove 13, and at the same time, the back plate 8 is placed horizontally so that the arc-shaped notches 83 and the sleeve 4 fit together to complete the placement and retraction.
