Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and in particular to an orthopedic rehabilitation training wheelchair. Background Art

[0002] Wheelchairs are a common means of transportation for people with limited mobility. Users use wheelchairs to exercise and participate in social activities. Existing wheelchair technology is relatively mature and is usually divided into two categories: electric and manual. Manual wheelchairs are mostly used for short-term use or rehabilitation training. Manual wheelchairs enable patients to exercise and participate in social activities with the help of wheelchairs. A manual wheelchair includes a seat, brackets on both sides of the seat, front and rear wheels mounted on the two brackets, and a footrest arranged under the seat. A brake structure is provided on the rear wheel. When moving, the wheelchair is controlled to move forward, backward and turn by rotating the handwheel rim on the rear wheel.

[0003] Due to mobility problems, users use wheelchairs for a long time every day, ranging from one or two hours to a whole day. They only leave the wheelchair when sleeping. Riding in a wheelchair causes the knees to bend, and long-term bending can easily lead to joint stiffness and thigh and calf muscle fatigue, which is not conducive to recovery. Existing wheelchairs lack the function to improve this problem. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide an orthopedic rehabilitation training wheelchair to solve the problem that the existing wheelchairs cause the knees to be bent for a long time, which easily leads to joint stiffness and thigh and calf muscle fatigue.

[0005] To achieve the above-mentioned purpose, the present invention provides an orthopedic rehabilitation training wheelchair, including a wheelchair body, and also including two stretching components fixed on both sides of the wheelchair body, the two stretching components are used to place the user's legs and can be rotated to horizontal, the stretching components include a mounting plate fixed to the wheelchair body bracket, a rotatable mounting shaft is provided in the mounting plate, a supporting member, an adjusting member and a stopping member are provided on the mounting shaft, the supporting member is fixed on the mounting shaft, and is used to place the user's feet and calves; the adjusting member is used to control the rotation of the mounting shaft to rotate the supporting member to horizontal; the stopping member is used to lock the adjusting member to keep the supporting member horizontal.

[0006] Principle of the technical solution: the stretching components are provided on both sides of the wheelchair body, and the stretching components are used to place the user's legs and can be rotated to a horizontal state. By rotating to a horizontal state, the patient's legs can be straightened, and joint stiffness, muscle fatigue and other problems caused by long-term bending can be relieved; the specific mounting plate is used to install the mounting shaft, and the mounting shaft is used to install the support member, the adjustment member and the stop member, wherein the support member is used to place the user's feet and calves, and is fixedly connected to the mounting shaft, and can rotate to a horizontal state with the mounting shaft to relieve the user's feet and calves; the adjustment member is used to control the rotation of the mounting shaft and drive the support member to rotate; the stop member is used to lock the adjustment member to keep the support member horizontal, so that the user can maintain a horizontal stretch state for a period of time, and relieve joint stiffness, muscle fatigue and other problems caused by long-term bending.

[0007] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention can stretch the legs of the user and effectively relieve problems such as joint stiffness and muscle fatigue.

[0008] 2. The present invention allows the user to adjust the state of both legs by himself through the adjusting piece, without the help of others, and is simple and convenient to use.

[0009] 3. The support member, the adjusting member and the stop member of the present invention are all installed on the installation shaft, which has a simple and compact structure, occupies little space, and does not affect the original structure of the wheelchair.

[0010] As a preferred embodiment of the present invention, the support member includes a rotating rod fixedly connected to the mounting shaft, a pedal is fixed to the lower end of the rotating rod, and a support plate is fixed to the side of the rotating rod.

[0011] Principle and beneficial effects of the technical solution: the rotating rod rotates with the installation axis to adjust the angle, the pedal is used to place the user's feet, and the support plate is used to support the user's calves in a horizontal state.

[0012] As a preferred embodiment of the present invention, the adjusting member includes a mounting box fixed to the side of the wheelchair body seat, the mounting box is provided with an opening, a worm is rotatably arranged in the mounting box, a rotary rod is arranged above the worm, the rotary rod is higher than the armrest of the wheelchair body, and is used to drive the worm to rotate; a worm wheel is fixed on the mounting shaft, and the worm wheel passes through the opening of the mounting box and engages with the worm.

[0013] Principle and beneficial effects of the technical solution: the installation box is used to install the worm and prevent the worm from being entangled in the user's clothes. The rotating rod is used to rotate the worm and drive the installation shaft to rotate through the worm gear to adjust the angle of the support so that it can be rotated to the horizontal.

[0014] As a preferred embodiment of the present invention, the rotary rod includes a connecting rod fixedly connected to the worm gear, a first telescopic rod is horizontally fixed on the connecting rod, and a handle is fixed on the extension rod of the first telescopic rod.

[0015] Principle and beneficial effects of the technical solution: the connecting rod is used to connect the worm and the first telescopic rod. The first telescopic rod has telescopic ability. It can be stored to reduce the extended length when not in use, and can also be extended to lengthen the rotating force arm to make rotating the worm more labor-saving. The handle is used to facilitate holding and facilitate the user to exert force.

[0016] As a preferred embodiment of the present invention, the stop member includes a ratchet fixed on the mounting shaft, and a pawl is rotatably arranged on the mounting plate. When the support member rotates horizontally, the ratchet can rotate, and when the support member tends to rotate in the vertical direction, the pawl resists the ratchet; a paddle is fixed on the ratchet.

[0017] Principle and beneficial effects of the technical solution: the ratchet rotates with the mounting shaft, and when the support member rotates horizontally, the pawl slides relative to the ratchet, and when the support member rotates vertically, the pawl resists the ratchet to keep the support member at its current angle; the paddle is used to facilitate the rotation of the pawl, staggering it from the ratchet to achieve an unlocking effect, allowing the support member to rotate downward.

[0018] As a preferred embodiment of the present invention, it also includes a fixed plate fixed under the wheelchair body seat, the fixed plate is wrapped around the outside of the mounting shaft, and a buffer is arranged in the fixed plate, and the buffer is used to slow down the speed of the support member when rotating in the vertical direction.

[0019] Principle and beneficial effects of the technical solution: the fixed plate is used to install the buffer component, and the buffer component is used to slow down the speed of the support component when it rotates in the vertical direction, so as to prevent the support component from rotating downward too quickly and causing impact injuries to the user's calf.

[0020] As a preferred embodiment of the present invention, the buffer member includes a coil spring, the outer ring of the coil spring is fixed in the fixed disk, the inner ring of the coil spring is fixed with a baffle, and the baffle is folded toward the outer ring of the coil spring; an arc block is fixed on the mounting shaft, when the support member rotates horizontally, the arc surface of the arc block maintains relative sliding with the coil spring, and when the support member rotates vertically, the back side of the arc block resists the baffle.

[0021] The principle and beneficial effects of the technical solution are as follows: the outer ring of the coil spring is fixedly connected to the fixed disk, and the inner ring can be rotated and compressed. When the support member rotates horizontally, the arc surface of the arc block maintains relative sliding with the coil spring and will not compress the coil spring. When the support member rotates vertically, the back side of the arc block presses against the baffle, compressing the coil spring, and providing a rebound force through the coil spring, thereby reducing the rotation speed.

[0022] As a preferred embodiment of the present invention, the buffer member includes a second telescopic rod and a spring, the second telescopic rod is fixed in the fixed plate, a friction block is fixed on the extension rod of the second telescopic rod, and the spring is arranged on the outside of the second telescopic rod for rebounding the friction block.

[0023] Principle and beneficial effects of the technical solution: the second telescopic rod is used to limit the rebound direction of the spring, and the spring pops out the friction block to press against the mounting shaft. When the mounting shaft rotates, the friction block rubs against it to form resistance, thereby reducing its rotation speed.

[0024] As a preferred embodiment of the present invention, a supporting block is fixed on the bracket of the wheelchair body, and the supporting block is used to support the lowered supporting plate.

[0025] Principle and beneficial effects of the technical solution: The abutment block is used to support the lowered support plate, which can limit the maximum angle of the downward rotation of the rotating rod to avoid excessive rotation angle to prevent the user's legs from being unable to support the legs.
