Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0017] Please see Figure 1-3 The present invention provides an embodiment of a wheelchair footrest with protective and adjustable features, comprising a connecting mounting hole 1, an adjusting support rod 2, an adjusting locking hole 3, a self-locking adjusting device 4, and a foot support part 5. The connecting mounting hole 1 is evenly provided through the upper end of the adjusting support rod 2, the adjusting locking hole 3 is evenly provided through the lower end of the adjusting support rod 2, the self-locking adjusting device 4 is provided at the bottom of the adjusting support rod 2, and the foot support part 5 is provided inside the self-locking adjusting device 4.

[0018] The self-locking adjustment device 4 includes an adjustment handle 6, a disassembly and mounting plate 7, a reset locking spring 8, a sliding locking pin 9, a sliding adjustment sleeve 10, and a locking socket 11. The locking socket 11 is symmetrically opened on both sides of the sliding adjustment sleeve 10. The adjustment handle 6 is located on the outside of the sliding adjustment sleeve 10. The two disassembly and mounting plates 7 are fixedly installed on the outside of the sliding adjustment sleeve 10 and the inside of the adjustment handle 6 by bolts, respectively. The reset locking spring 8 is fixedly located between the middle of the two disassembly and mounting plates 7. The sliding locking pin 9 is fixedly installed on the inside of both ends of the adjustment handle 6. The sliding locking pin 9 is inserted into the locking socket 11 and the adjustment locking socket 3 distributed on the outside of the sliding adjustment sleeve 10.

[0019] The locking holes 11 at both ends of the inner side of the sliding adjusting sleeve 10 are equipped with protective locking pins 12, and the front end of the protective locking pins 12 is inserted into the adjusting locking holes 3. The protective locking pins 12 serve as a safety device, and are inserted into the locking holes 11 and the corresponding adjusting locking holes 3 on the adjusting support rod 2 to prevent accidental unlocking.

[0020] The foot support 5 includes a support rod 13, a locking threaded post 14, a sliding adjustment side baffle 15, a support pedal 16, and a fixed side baffle 17. The fixed side baffle 17 is fixedly installed on the upper inner end of the support pedal 16. The sliding adjustment side baffle 15 is slidably engaged with the upper side end of the support pedal 16 away from the fixed side baffle 17. The locking threaded post 14 is evenly threaded into the sliding adjustment side baffle 15, and the bottom end of the locking threaded post 14 is in contact with the support pedal 16. The middle of the bottom end of the support pedal 16 is fixedly connected to the support rod 13.

[0021] The inner end of the support rod 13 is fixedly connected to the sliding adjusting sleeve 10 away from the middle of the adjusting handle 6, thus providing support.

[0022] The sliding adjusting sleeve 10 is slidably mounted on the adjusting support rod 2, and the locking socket 11 has the same diameter as the adjusting locking socket 3, so that the sliding locking pin 9 and the protective locking pin 12 can be easily inserted.

[0023] Working principle: By pulling the adjustment handle 6, the reset locking spring 8 is compressed, causing the sliding locking pin 9 to disengage from the adjustment locking socket 3. At this time, the sliding adjustment sleeve 10 can be slid up and down to adjust the height of the foot support 5. After releasing the adjustment handle 6, the reset locking spring 8 pushes the sliding locking pin 9 to automatically insert into the adjustment locking socket 3 at the corresponding position after adjustment, achieving rapid self-locking. The protective locking pin 12 serves as a safety device, inserted into the locking socket 11 and the corresponding adjustment locking socket 3 on the adjustment support rod 2, preventing accidental unlocking. The sliding adjustment side baffle 15 moves laterally along the support pedal 16, adjusting the distance between it and the fixed side baffle 17 according to the foot size. Tightening the locking threaded pin 14 presses its bottom against the support pedal, fixing the side baffle position and forming a suitable anti-slip enclosure space. The adjustment support rod 2 is fixed to the wheelchair frame through the connecting mounting hole 1. The foot support 5 is connected to the sliding adjustment sleeve 10 via the support rod 13, realizing the linkage adjustment of height and width.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
