[0016] In order to illustrate the technical solutions described in the present utility model, the following is illustrated through specific embodiments.

[0017] For the sake of convenience of description, only parts related to the embodiments of the present utility model are shown.

[0018] Combined with Figures 1 - 3As shown in the figure, the palm rehabilitation device includes a housing 1. An opening 2 is formed on the front side of the housing. A partition 3 is provided inside the housing 1. Corresponding sliding grooves 4 are formed on both the partition 3 and one side of the housing 1. Short grooves 5 are correspondingly formed on the other side of the partition and the housing. Sliders 6 are provided in the sliding grooves. A cam 7 is rotatably provided between the two sliders 6. A sliding seat 8 is provided in the short groove 5. A driving motor 9 is provided on the sliding seat 8. The driving shaft of the driving motor 9 passes through the slider on the same side and is connected to the shaft rod 10 of the cam 7. A backing plate 11 is provided on the inner wall of the rear side of the housing 1 facing the opening. A sliding mechanism for driving the cam 7 to slide back and forth is further provided inside the housing 1.

[0019] In the existing life process, the hand is one of the most easily injured body parts. Minor injuries include bruises, sprains or contusions, while severe injuries can result in bone fractures. Although emergency treatment for hand injuries is important, rehabilitation training after treatment is also crucial. Especially in cases of bone fractures, ligament injuries, etc., disuse muscle atrophy caused by immobilization, reduced movement or other reasons is very common, which not only brings inconvenience to patients but also increases their pain.

[0020] This palm rehabilitation device mainly massages the palm to stretch the palm muscles, thereby promoting blood circulation in the palm and facilitating the rapid recovery of the palm.

[0021] When using this rehabilitation device to rehabilitate an injured palm, the patient inserts the injured palm into the rehabilitation device through the opening. At this time, the entire palm is inside the housing and also on the backing plate. Turn on this rehabilitation device. The driving motor drives the cam to rotate. The cam rolls on the palm to achieve the massage effect on the palm. At the same time, the sliding mechanism drives the cam to slide back and forth. In this way, the cam moves back and forth along the direction of the palm during rotation, so as to massage the entire palm, stretch the palm muscles, and promote blood circulation in the entire palm to achieve the effect of rehabilitating the palm. And the structure of the entire rehabilitation device is relatively simple, small in size, easy to carry, and has good rehabilitation treatment effect.

[0022] In this palm rehabilitation device, a support platform 12 is further formed on the front side of the housing 1. When the palm is inserted into the housing through the opening, the wrist is supported on the support platform. This can make the patient more comfortable during palm rehabilitation treatment. In addition, a shallow groove matching the backing plate is formed on the support platform, and the backing plate 11 is located in the shallow groove.

[0023] In this rehabilitation device, the cam 7 is covered with bumps. When the cam rotates, the bumps massage the palm. By setting bumps on the cam, the rehabilitation effect of this rehabilitation device can be improved, and at the same time, the comfort of the patient during treatment can be further improved.

[0024] As a preferred structure, as Figure 3, the sliding mechanism includes a pair of short blocks 14. A rotating shaft 15 is rotatably arranged on the short blocks. Eccentric wheels 16 are arranged at both ends of the rotating shaft 15. A connecting rod 17 is rotatably arranged at the eccentric position of the eccentric wheel 16. The connecting rod 17 is rotatably connected to the shaft rod 10 on the same side. A rotating motor 18 is further arranged in the shell. Driving wheels 19 and driven wheels 20 are respectively arranged on the driving shaft of the rotating motor and the rotating shaft 15. And a matching belt 21 is sleeved on the driving wheel 19 and the driven wheel 20.

[0025] When using this rehabilitation instrument to treat an injured palm, the sliding mechanism drives the cam to move back and forth along the palm, so as to achieve the purpose of massaging the entire palm. Specifically: the rotating motor drives the driving wheel to rotate. Under the linkage of the driven wheel, the rotating shaft rotates. A pair of eccentric wheels rotate synchronously. Under the action of the eccentric wheels, the two connecting rods drive the cam to move back and forth, and the sliding seat also moves back and forth synchronously.

[0026] Furthermore, as a preferred structure, as Figure 2 , a pair of protrusions (blocked in the figure) are formed at the rear end of the backing plate 11. A pair of pressure springs 22 are horizontally arranged on the inner wall at the rear side of the shell. The pressure springs 22 are connected to the protrusions on the same side. A cavity is formed between the rear end of the backing plate and the shell. A resisting plate 23 is obliquely arranged in the cavity of the shell.

[0027] During the process of the cam massaging the palm, the cam will squeeze the palm. Under the squeezing of the cam, the palm will squeeze the backing plate up and down. The rear end of the backing plate will move up and down slightly under the action of the pressure spring, playing a buffering effect, making the entire rehabilitation process more comfortable and improving the massage effect at the same time. And the resisting plate plays a role in supporting and limiting the backing plate, making the backing plate move more stably up and down.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
