Description
Technical Field
[0001] The utility model relates to the technical field of upper limb rehabilitation, in particular to an upper limb auxiliary rehabilitation device. Background Art
[0002] Rehabilitation equipment is mainly used to help patients carry out passive movements and daily activities to promote rehabilitation. Most of them are made of stainless steel, iron, plastic, and wood. They are made into the required parts through machining, welding, injection molding and other production processes. Finally, several or hundreds of parts are assembled into rehabilitation equipment. Upper limb rehabilitation trainers can help patients with upper limb rehabilitation training more effectively.
[0003] However, the existing upper limb rehabilitation training devices usually have some defects in actual use. The main defect is that when patients with different rehabilitation training degrees use the same device, the force required to rotate the device will be poorly adjustable, resulting in inconsistent training effects for patients at different recovery stages. Usually, as the recovery degree increases, the training efficiency will continue to decrease. At the same time, the training angle cannot be adjusted, which makes it more troublesome to use. For this reason, we propose an upper limb auxiliary rehabilitation device. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0008] Furthermore, the angle adjustment mechanism includes a fixed shaft, which is rotatably connected to one of the fixed plates, a top plate is connected to the top of the fixed plate, one end of the fixed shaft is connected to the connecting shaft, and the other end of the fixed shaft is connected to a rotating wheel, a plurality of evenly distributed limiting grooves are provided on the rotating wheel, a limiting rod is slidably connected to the top plate, and the limiting rod is clamped with the inner side of the limiting groove.
[0009] Furthermore, the angle adjustment mechanism also includes a pull plate, which is connected to the top of the limiting rod. The limiting rod is sleeved with a spring, one end of the spring is connected to the pull plate, and the other end of the spring is connected to the top plate.
[0010] Furthermore, the upper limb rehabilitation component also includes a bidirectional screw, which is rotatably connected to the inner side of the box body, and two symmetrically distributed sliding sleeves are threadedly connected to the bidirectional screw, and the two U-shaped plates are respectively connected to the two sliding sleeves.

[0013] The beneficial effects of the utility model are as follows:
[0014] The utility model uses a rotating component to drive the upper limb rehabilitation component to rotate on the top of the base plate, thereby adjusting the angle of the upper limb rehabilitation component. The rotating plate rotates between the two fixed plates to drive the upper limb rehabilitation component to rotate. The angle adjustment mechanism allows the rotating plate to rotate between the two fixed plates, or the rotating plate is limited to adjust the angle of the rotating plate, thereby adjusting the angle of the upper limb rehabilitation component, thereby solving the problem that the training angle cannot be adjusted and is troublesome to use.

This solves the problem that when patients with different rehabilitation training degrees use the same device, the force required to rotate the device is poorly adjustable, resulting in inconsistent training effects of the device for patients at different recovery stages, and usually the problem that the training efficiency continues to decrease as the recovery degree increases.

The rotating component is arranged on the top of the base plate 1 and connected thereto, the upper limb rehabilitation component is arranged on the top of the rotating component and connected thereto, the clamping component is arranged at both ends of the base plate 1 and connected thereto, the rotating component includes two fixed plates 7 and an angle adjustment mechanism, the two fixed plates 7 are connected to the base plate 1, a rotating plate 10 is rotatably connected between the two fixed plates 7, the angle adjustment mechanism is connected to one of the fixed plates 7, the upper limb rehabilitation component is connected to the rotating plate 10, the upper limb rehabilitation component includes a box body 9 connected to the rotating plate 10, the box The body 9 is rotatably connected with a rotating shaft 11, and both ends of the rotating shaft 11 are connected with connecting rods 12 that are staggered. The connecting rod 12 is connected with a handle 13 at one end away from the rotating shaft 11. The rotating shaft 11 is connected with a fixed wheel 24, and the fixed wheel 24 is sleeved with a second rubber sleeve 28. Two symmetrically distributed U-shaped plates 27 are slidably connected to the inner side of the box body 9, and the inner sides of the two U-shaped plates 27 are rotatably connected with moving wheels 22, and the two moving wheels 22 are sleeved with a first rubber sleeve 23, and the two first rubber sleeves 23 are in conflict with the outer side of the second rubber sleeve 28. In some embodiments, the upper limb rehabilitation component is driven on the top of the bottom plate 1 by rotating the component. The angle of the upper limb rehabilitation component is adjusted by rotating the rotating plate 10 between the two fixed plates 7, thereby driving the upper limb rehabilitation component to rotate, and the angle adjustment mechanism is used to rotate the rotating plate 10 between the two fixed plates 7, or the rotating plate 10 is limited to adjust the angle of the rotating plate 10, thereby adjusting the angle of the upper limb rehabilitation component, thereby solving the problem that the training angle cannot be adjusted and it is troublesome to use. Through the upper limb rehabilitation component, the patient performs upper limb rehabilitation on the patient, and the patient holds the two handles 13 with both hands respectively, rotates the two handles 13, thereby driving the connecting rod 12 to rotate, thereby driving the rotating shaft 11 to rotate, and then driving the fixed wheel 2 4 rotates, and the two U-shaped plates 27 slide on the inner side of the box body 9, so that the first rubber sleeve 23 on the moving wheel 22 conflicts with the second rubber sleeve 28 on the fixed wheel 24, thereby increasing the damping of the fixed wheel 24, and then the force required by the device can be flexibly adjusted to meet the needs of upper limb rehabilitation of patients at different stages. In this way, it is solved that when patients with different rehabilitation training degrees use the same device, the force required to rotate the device is poorly adjustable, resulting in inconsistent training effects of the device for patients at different recovery stages.

The limiting rod 19 slides downward so that the limiting rod 19 is engaged with the inner side of one of the limiting grooves 17, thereby limiting the rotating wheel 16, thereby limiting the fixed shaft 15, and then limiting the connecting shaft 8.
