Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1
[0027] Please see Figures 1-6A foldable side support structure for wheelchair balancing includes a handrail support seat 2 fixedly mounted on a wheelchair handrail tube 1, and a foldable support plate 3 adapted to the handrail support seat 2. A support side plate 4 is rotatably connected to one side of the foldable support plate 3. Connecting seats 5 are provided on opposite sides of the support side plate 4. Each connecting seat 5 has a locking ring 6 adapted to the wheelchair handrail tube 1 on its side. Locking bolts 7 are provided on the side of the locking ring 6 for locking. Several inclined support plates 8 are provided between the foldable support plate 3 and the support side plate 4 for support. The foldable support plate 3 faces... One side of the support side plate 4 has a storage groove 9 that is adapted to several inclined support plates 8. A connecting shaft 10 is fixedly connected between the ends of several inclined support plates 8. The two ends of the connecting shaft 10 extend beyond the side of the inclined support plate 8. The opposite side walls of the storage groove 9 are provided with a first sliding groove 11 that is adapted to the connecting shaft 10. The opposite side walls of the storage groove 9 are provided with a number of first snap-fit grooves 12 that communicate with the first sliding grooves 11 and are adapted to the connecting shaft 10. One side of the support side plate 4 has a number of second snap-fit grooves 13 that are adapted to the ends of the inclined support plates 8.
[0028] In this embodiment, the wheelchair is equipped with a wheelchair armrest tube 1 and an armrest support seat 2 for placing the patient's arm. This auxiliary support structure is snapped onto the side of the wheelchair armrest tube 1 using snap-fit rings 6, and the snap-fit rings 6 are locked to the side of the wheelchair armrest tube 1 using locking bolts 7. Two snap-fit rings 6 fix the position of the connecting seat 5, and two connecting seats 5 fix the position of the support side plate 4. When the patient is weak and needs to lie prone on the armrest support seat 2, the folding support plate 3, hinged to the support side plate 4, is rotated. Then, the tilting support plate 8 supports the folding support plate 3, extending the area of the armrest support seat 2. The patient can place a soft cushion such as a pillow on the armrest support seat 2 and the folding support plate 3 to increase support for the patient. The wheelchair maintains a balanced state and can be folded when not in use, saving space and improving patient comfort. When the support side plate 4 needs to be unfolded, one end of the two inclined support plates 8 located in the storage slot 9 is rotated out, one end of the connecting shaft 10 slides in the first sliding groove 11, and a suitable first locking groove 12 is selected to lock the connecting shaft 10 into the first locking groove 12. The other end of the inclined support plate 8 is locked into the appropriate second locking groove 13 to support the support side plate 4. If the angle of the support side plate 4 needs to be adjusted, the angle of the support side plate 4 can be adjusted by selecting the appropriate first locking groove 12 and second locking groove 13, thus improving the applicability of the side support structure.
[0029] Example 2
[0030] Please see Figure 3 and Figure 6This embodiment includes the above embodiment, and further includes: a sliding seat 14 is slidably connected to the side of the connecting seat 5, a second sliding groove 16 adapted to the sliding seat 14 is opened on the side of the connecting seat 5, a connecting post 15 is provided between the sliding seat 14 and the snap ring 6, a first threaded post 17 penetrating the connecting seat 5 is provided on one side of the sliding seat 14, a first adjusting groove 19 adapted to the first threaded post 17 is opened on one side of the connecting seat 5, a first limiting nut 18 is threadedly connected to the side of the first threaded post 17, a connecting hole 25 is opened on the side of the sliding seat 14, and one end of the connecting post 15 is threadedly connected to the connecting hole 25.
[0031] In this embodiment, the device is installed on a wheelchair. The locking ring 6 is rotated along the axis of the connecting seat 5 to thread one end of the connecting post 15 to the connecting hole 25. The position of the locking ring 6 is adjusted by sliding the sliding seat 14 within the second sliding groove 16. The locking ring 6 can be locked onto the side of the horizontal tube of the wheelchair armrest tube 1, or onto the side of the vertical tube of the wheelchair armrest tube 1. Alternatively, one locking ring 6 can be installed on the side of the vertical tube and one on the side of the horizontal tube, depending on the shape of the wheelchair armrest tube 1 on the wheelchair, thus improving the applicability of the overall device. When the sliding seat 14 moves, the first threaded post 17 slides within the first adjusting groove 19. After the position of the sliding seat 14 is adjusted, the first limiting nut 18 threaded to the side of the first threaded post 17 is tightened to limit and fix the position of the sliding seat 14.
[0032] Example 3
[0033] Please see Figures 1-3 This embodiment includes all the above embodiments, and further includes: a connecting plate 20 is fixedly connected to each of the opposite sides of the support side plate 4; a connecting block 21 adapted to the connecting plate 20 is fixedly connected to one side of the connecting seat 5; a second threaded post 22 penetrating the connecting plate 20 is fixedly connected to one end of the connecting block 21; a second limiting nut 23 is threadedly connected to the side of the second threaded post 22; a second adjusting groove 24 is provided through the side of the connecting plate 20; and the second adjusting groove 24 is adapted to the second threaded post 22.
[0034] In this embodiment, the specific implementation method is as follows: After the positions of the connecting seat 5 and the snap ring 6 are installed, the second threaded posts 22 on both sides of the support side plate 4 are passed through the second adjustment groove 24. The position of the support side plate 4 can be adjusted through the second adjustment groove 24. The second limit nut 23 on the side of the threaded post 22 is locked to facilitate the installation of the whole device and the adjustment of the position of the folding support plate 3.
