The air charging port is a one-way air port structure, which can only take in air but not out; There is a spring I10, and the air cylinder 4 is connected to the back cushion 2 of the inflatable seat with a hose; the leg frame 3 is rotatably connected to the right end of the main frame body 1, and the left side of the leg frame 3 has a chute I11, and a slide block is slidably connected in the chute I11 12. A connecting rod 13 is connected to the slider 12 in rotation, and the other end of the connecting rod 13 is connected to the wheel disc of the large gear 14. When the large gear 14 rotates, the connecting rod 13 can drive the leg 3 to swing up and down continuously, so that the placed The legs on the leg frame 3 can be continuously bent and exercised to promote blood circulation in the legs and accelerate injury recovery; the lower end of the main frame body 1 is provided with a chute II15, and a mounting seat 16 is slidably connected to the chute II15. The rotating shaft of the large gear 14 is connected to the mounting base 16. Because the mounting base 16 has a heavy load, several fixing strips should be added to the chute II 15 to improve the stability of the mounting base 16. The main frame body 1 is still on the left side of the chute II 15. There is a spring groove, and a spring II17 is installed in the spring groove. The lower end of the main frame body 1 is also fixedly connected with a horizontally placed hand lifter 18. The hand lifter 18 is located on the right side of the chute II15, and the hand lifter 18 The crank handle is a bent storage structure, and when not in use, its right-angle structure can be stored and transformed into a strip structure to prevent bumping; the rotation shaft of the driving wheel 5 is fixedly connected with a driving gear 19, and the mounting seat 16 is located at the bottom of the chute II 15. At the left end, the large gear 14 is meshed with the driving gear 19, and the mounting seat 16 is pushed up by rotating the hand lifter 18, so that the large gear 14 is meshed with the driving gear 19, and the rotation of the driving wheel 5 can drive the swing of the stand 3, that is When the wheelchair is walking, the leg frame 3 can constantly swing to perform restorative exercise for the lower limbs. The diameter of the large gear 14 is greater than that of the driving gear 19, reducing the transmission ratio so that the leg frame 3 swings slowly, avoiding excessive speed of swing and causing discomfort in the limbs. When the injury is not suitable for lower limb movements, the hand lifter 18 can be shaken to retract, and the mounting seat 16 is pushed under the action of the spring II 17 to separate the large gear 14 from the driving gear 19. At this time, it can be used as an ordinary wheelchair. Finally, the crank handle of the hand-operated lifter 18 is bent and put away, which does not affect the appearance; the main frame body 1 is also fixedly connected with a driven frame 20, and the rotating shaft on the driven frame 20 is connected with a pinion 21, and the pinion 21 and The driving gear 19 is meshed and connected, the rotating shaft of the pinion 21 is fixedly connected with a crank connecting rod 22, and the main frame body 1 is also fixedly connected with a slider 24, and the upper end of the inner wall of the slider 24 is provided with a threaded strip for matching with the gas cylinder 4. Threaded groove, slidingly connected with push block 25 in the slide tube 24, the connecting rod end of the crank connecting rod 22 is connected with the push block. The block 25 is connected by rotation. When the driving wheel 5 rotates, the pinion 21 can drive the push block 25 to slide up and down in the sliding tube 24 through the crank connecting rod 22. When the seat is hard and needs to be made softer, the gas cylinder 4 is screwed At the upper end of the slider 24, when the push block 25 slides, the push rod of the air cylinder 4 can be pushed to move for inflating. When the push block 25 slides down, the spring I10 can push the push rod to extend to ensure the normal operation of inflating. The diameter of the pinion 21 is less than The diameter of the driving gear 19 increases the transmission ratio to accelerate the moving frequency of the push block 25 and increase the pumping speed. The side wall of the sliding cylinder 24 is also fixedly connected with a placement ring 26. The inner diameter of the placement ring 26 is larger than the diameter of the gas cylinder 4 and smaller than the two ends of the block 9 distance, when it is not necessary to inflate, the inflator 4 thread can be unscrewed and placed in the placement ring 26, and the adjustment of the softness of the seat can be conveniently carried out through the inflator 4 and the deflation head 8, and the seat cushion and the backrest can also be adjusted. The cushions are separated and the air outlets are set separately to facilitate the individual adjustment of the softness of the seat cushion and the back cushion.

In order to facilitate single-person operation of the patient, the width of the main frame body 1 should be enlarged without affecting normal use in actual production to ensure that the slider 24 and the hand lifter 18 are located on the side of the back cushion 2 of the inflatable seat instead of directly below, so that It can also ensure that the hand-operated lifter 18 can rotate normally. Because the movable leg-swinging wheelchair has no folding function, it is troublesome for general household transportation. Parts such as gear 14 are preferably made of hollow aluminum alloy or reinforced plastic, so as to reduce the weight increase as much as possible; it should be noted that if the patient is injured by a fracture, it is necessary to ensure that the large gear 14 and the driving gear 19 are in the same position before the wheelchair moves. Separated state, avoids the aggravation of the state of an illness because of leg movement driven by leg support 3.
