[0030] One end of the telescopic spring 204 is fixedly connected with the mounting plate 105, and the other end of the telescopic spring 204 is fixedly installed with the mounting block 205, and the mounting block 205 is fixedly connected with the movable rod 203, so that the movable rod 203 can be automatically reset after moving, the inside of the two fixed sleeves 202 is symmetrically and slidably connected with the positioning rods 206, and the top side of the two positioning rods 206 is hingedly connected with the connecting rods 207, and the end of the connecting rod 207 away from the positioning rod 206 is hingedly connected with the movable rod 203, so that the movable rod 203 can drive the positioning rod 206 to move, the inside of the fixed sleeve 202 is fixedly installed with the guide rod 208, and the outside of the guide rod 208 is symmetrically and slidably connected with the positioning blocks 209, and the two positioning blocks 209 are fixedly connected with the two positioning rods 206 respectively, so as to limit the movement of the positioning rod 206, the adjusting assembly 3 comprises the limiting rods 301 which are symmetrically and slidably connected inside the two sides of the supporting frame 102, and the two sides of the adjusting plate 103 are symmetrically provided with a plurality of limiting grooves 302, and the limiting rods 301 are clamped and connected with the limiting grooves 302, and the outside of the two limiting rods 301 is sleeved with the return springs 303, one end of the return spring 303 is fixedly connected with the supporting frame 102, and the other end of the return spring 303 is fixedly installed with the movable plate 304, and the movable plate 304 is fixedly connected with the limiting rod 301, so as to adjust the height of the headrest 104, the side of the two movable plates 304 located on the limiting rod 301 is fixedly installed with the moving rods 306, and the outside of the two moving rods 306 is symmetrically and slidably connected with the limiting frames 305, and the limiting frames 305 are fixedly connected with the supporting frame 102, and the side of the supporting frame 102 is rotatably connected with the rotating part 307, and the side of the rotating part 307 is symmetrically hingedly connected with the pull rods 308, and the ends of the two pull rods 308 away from the rotating part 307 are respectively hingedly connected with the two moving rods 306, so that pulling one side of the movable plate 304 makes the two movable plates 304 move away from each other, and the cross sections of the fixed sleeve 202 and the mounting hole 201 are square, so that the fixed sleeve 202 is not easy to move inside the mounting hole 201.

[0031] Working principle: before using the wheelchair for cerebral palsy children, the overall situation of the device needs to be checked to determine whether it can work normally, according to Figure 1 - Figure 5As shown, the positioning assembly 2 is symmetrically arranged at the connection between the mounting plate 105 and the folding hollow plate 101. When the child with cerebral palsy defecates on the folding wheelchair 1, the seat cushion 106 will be contaminated. When the seat cushion 106 is disassembled and cleaned, the two mounting blocks 205 are pulled to move the movable rod 203. The movable rod 203 can stretch the extension spring 204 while moving. After the movable rod 203 moves, the connecting rod 207 can be pulled to rotate. After the connecting rod 207 rotates, the positioning rod 206 can be pulled to move, so that the positioning rod 206 retracts into the fixing sleeve 202. When the positioning rod 206 moves, the positioning block 209 slides on the guide rod 208 to limit, so that the fixing sleeve 202 can lose the limit, and the mounting plate 105 and the seat cushion 106 can be removed. When the seat cushion 106 is installed, the fixing sleeve 202 on the seat cushion 106 is inserted into the mounting hole 201 and the mounting block 205 is moved, so that the positioning rod 206 retracts into the fixing sleeve 202. Since the fixing sleeve 202 and the mounting hole 201 are square, the fixing sleeve 202 is not easy to move inside the mounting hole 201. After the mounting plate 105 is attached to the folding hollow plate 101, the mounting block 205 is loosened, the movable rod 203 is reset under the action of the extension spring 204, the positioning rod 206 extends out of the fixing sleeve 202, so that the fixing sleeve 202 can be positioned, and the seat cushion 106 can be positioned. When the folding wheelchair 1 is folded, the mounting plate 105 and the seat cushion 106 can be removed, so that the folding wheelchair 1 and the folding hollow plate 101 are folded. When the child with cerebral palsy takes a bath, the seat cushion 106 can be removed, and the child with cerebral palsy can take a bath on the folding wheelchair 1. The folding hollow plate 101 facilitates water discharge, the folding wheelchair 1 has a certain waterproofness, the positioning assembly 2 can disassemble the seat cushion 106 alone, the seat cushion 106 can be easily disassembled and cleaned, the seat cushion 106 can be easily cleaned and dried alone, and the practicality and convenience are improved;

[0032] The adjusting assembly 3 is arranged inside and outside the support frame 102, and the comfort of use of the folding wheelchair 1 can be improved by lifting the headrest 104 on the adjusting plate 103; when the height of the headrest 104 is adjusted according to the height of the child with cerebral palsy, one side of the movable plate 304 is pulled to move, after the movable plate 304 on one side moves, the moving rod 306 is driven to move, after the moving rod 306 on one side moves, the rotating piece 307 is pulled to rotate through the pull rod 308, after the rotating piece 307 rotates, the other side of the moving rod 306 is pulled to move through the other pull rod 308, so that the movable plate 304 on one side is pulled to make the two movable plates 304 move away from each other, thereby driving the two limiting rods 301 to move, while the limiting rods 301 move, the return spring 303 is stretched, so that the limiting rods 301 are separated from the limiting grooves 302, the adjusting plate 103 loses the limiting, the height of the adjusting plate 103 is adjusted to adjust the height of the headrest 104, after the adjustment, the limiting rods 301 are aligned with the other limiting grooves 302, the movable plate 304 is loosened, the limiting rods 301 are clamped with the limiting grooves 302 under the action of the return spring 303, thereby limiting the adjusting plate 103, when the folding wheelchair 1 is folded, the adjusting plate 103 can be removed by pulling the movable plate 304, thereby removing the headrest 104, since the support frame 102 is installed on one side above the rear side of the folding wheelchair 1, the support frame 102 does not affect the folding of the folding wheelchair 1, the height of the headrest 104 is adjusted according to the height of the user through the adjusting assembly 3, and the applicability of the headrest 104 is improved.

[0033] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
