Technical Field
[0001] The utility model relates to the technical field of rehabilitation wheelchairs, in particular to a wheelchair. Background Technique
[0002] Sarcopenia, also known as muscle attenuation syndrome, skeletal muscle reduction, and sarcopenia, is a disease associated with aging-related progressive reduction in skeletal muscle mass, accompanied by a decrease in muscle strength and / or muscle function. As one of the senile diseases, sarcopenia has the characteristics of high incidence, insidious progression, progressive aggravation, and extensive adverse effects. Due to the case characteristics of sarcopenia, most sarcopenia patients rely on wheelchairs to move or travel.
[0003] When the above device is in use, it does not have a structure for exercising the patient's arms and legs with the help of a wheelchair, so that sarcopenia patients can only move to the rehabilitation center with the help of a wheelchair for rehabilitation training during the illness, and cannot directly use the wheelchair to rehabilitate the arm muscles and leg muscles, which is not convenient for use. Based on the existing technical deficiencies, the utility model designs a wheelchair. Content of the Utility Model

[0009] As a preferred technical solution of the present utility model, a slot is provided on the lower surface of the bottom plate, a cushion is provided on the upper surface of the bottom plate, a plug rod is fixedly connected to the lower surface of the cushion, plugging grooves are opened on both the slot and the plug rod, a fixing plate is fixedly connected to the lower surface of the bottom plate, a pull rod is slidably connected inside the fixing plate, a pulling plate is fixedly connected to the pull rod, a limiting rod is fixedly connected to the pulling plate, the plug rod is movably inserted inside the slot, and the limiting rod is movably inserted inside the plugging groove.
[0010] As a preferred technical solution of the present utility model, a backrest is fixedly connected to the wheelchair frame body, a handle is fixedly connected to the wheelchair frame body, a front moving wheel is rotatably connected to the bottom of the wheelchair frame body, a rear moving wheel is rotatably connected to the bottom of the wheelchair frame body, and a storage bag is fixedly connected to the back surface of the backrest.
[0011] As a preferred technical solution of the present utility model, the limiting plate is slidably connected inside the lifting groove, and the top end of the spring is in contact with the limiting plate.
[0012] As a preferred technical solution of the present utility model, the vertical surface of the slider is in contact with the limiting block. Both ends of the elastic band are respectively fixedly connected to the inner cavity wall of the exercise plate and one side of the slider. The slider is slidably connected inside the exercise plate.
[0013] Compared with the prior art, the present utility model has the following beneficial effects:
[0014] 1. For this wheelchair, by flipping the top cover to one side to open the exercise plate, then rotating the grip upward to make it vertical, and then holding the grip and sitting on the bottom plate in the correct posture. At this time, pushing the grip forward makes the grip drive the slider to slide under the limitation of the slide bar. Since the slider is connected to the elastic band, a relatively large force is required to move the grip forward. When the user pushes the grip forward until the arm is fully extended or semi-extended, reduce the force of the arm to control the slider to slowly move backward under the traction of the elastic band until the slider contacts the limiting block before completely relaxing for the next set of exercises. This device is convenient for exercising the arm muscles.
[0015] 2. For this wheelchair, after adjusting the seat cushion to a comfortable height, sit on the seat cushion, place both feet on the footrests and maintain a correct sitting posture. At this time, use force with the legs to step down on the footrests to make them move downward. During the downward movement of the footrests, drive the sleeves to move downward along with them under the limitation of the lifting grooves and the limiting plates. Since there is a spring between the bottom of the inner cavity of the lifting groove and the limiting plate, a relatively large force is required for the patient to move the footrests when stepping down. When the user's legs are pushed downward to the maximum distance, slowly relax and reduce the force exerted by the legs to kick, so that the sleeves and the footrests are slowly pushed upward under the action of the spring until they are reset, and then the next set of leg muscle exercises can be carried out.

[0028] Please refer to Figure 3 , a slot 201 is provided on the lower surface of the bottom plate 2, a cushion 202 is provided on the upper surface of the bottom plate 2, a plug rod 203 is fixedly connected to the lower surface of the cushion 202, plugging grooves 204 are provided on both the slot 201 and the plug rod 203, a fixing plate 205 is fixedly connected to the lower surface of the bottom plate 2, a pull rod 206 is slidably connected inside the fixing plate 205, a pull plate 207 is fixedly connected to the pull rod 206, a limiting rod 208 is fixedly connected to the pull plate 207, the plug rod 203 is movably inserted inside the slot 201, and the limiting rod 208 is movably inserted inside the plugging groove 204.
[0029] By providing the slot 201 and the plug rod 203, it is convenient to realize the vertical lifting of the cushion 202. By providing the limiting rod 208, it is convenient to adjust and fix the sitting height of the cushion 202 after adjustment.
[0030] Working principle: When a wheelchair is in use, in the initial state, first, the front moving wheels 103 and the rear moving wheels 104 are provided at the bottom of the wheelchair frame main body 1, and a handle 102 is provided on the wheelchair frame main body 1 to facilitate the user to move or push by himself. The slot 201 installed on the bottom plate 2 inside the wheelchair frame main body 1 is connected to the cushion 202 through the plug rod 203, and the limiting rod 208 is inserted into the plugging groove 204 provided on the slot 201 and the plug rod 203 to facilitate the adjustment of the use height of the bottom plate 2. The connecting rod 301 provided on the front surface of the wheelchair frame main body 1 is sleeved with the sleeve 303 under the limitation of the lifting groove 302 and the limiting plate 304, and a spring 305 is provided between the two to facilitate leg muscle exercise. The slider 403 limited by the sliding rod 402 is slidably connected inside the exercise plate 401 provided on the wheelchair frame main body 1, and while the slider 403 is pulled by the elastic band 404, a grip 405 is further provided on the top to facilitate the patient to hold and exercise the arm muscles;
[0031] When the patient needs to exercise the arm muscles, first flip the top cover 407 to one side to open the exercise board 401, then rotate the grip 405 upward to make it vertical, and then hold the grip 405 and sit on the bottom plate 2 in the correct posture. At this time, push the grip 405 forward, so that the grip 405 drives the slider 403 to slide under the limit of the slide bar 402. Since the slider 403 is connected to the elastic band 404, a relatively large force is required to move the grip 405 forward. When the user pushes the grip 405 forward until the arm is fully extended or semi-extended, reduce the force of the arm and control the slider 403 to slowly move backward under the traction of the elastic band 404 until the slider 403 contacts the limit block 406, and then completely relax to perform the next set of exercises. This device is convenient for exercising the arm muscles.
[0032] When it is necessary to exercise the leg muscles, first adjust the seat cushion 202 to a comfortable height. After sitting on the seat cushion 202, step on the footrest 306 with both feet and maintain the correct sitting posture. At this time, use the legs to step on the footrest 306 downward to make it move downward. During the downward movement of the footrest 306, the sleeve 303 is driven to move downward along with it under the limit of the lifting groove 302 and the limit plate 304. Since there is a spring 305 between the bottom of the inner cavity of the lifting groove 302 and the limit plate 304, a relatively large force is required for the patient to step on the footrest 306 downward. When the user's leg kicks downward to the maximum distance, slowly relax and reduce the force of the leg kicking, so that the sleeve 303 and the footrest 306 are slowly pushed upward under the action of the spring 305 until they are reset, and then the next set of leg muscle exercises can be performed.
