[0002] Finger injuries are extremely common in various accidents, sports injuries, and some diseases (such as rheumatoid arthritis). These injuries can lead to various functional impairments such as stiff finger joints, muscle atrophy, and limited mobility. For people engaged in manual labor, artistic creation, or occupations that require frequent use of their fingers, finger dysfunction may mean limited career development or even loss of work ability.

[0003] There are many types of finger rehabilitation exercisers on the market. Existing finger rehabilitation exercisers usually use springs as the tension source. However, they lack a mechanism to adjust the tension of the springs at different rehabilitation stages and for individual differences. They require the use and replacement of springs with different elastic coefficients, and cannot adjust the spring tension anytime and anywhere, which reduces the applicability of the device. Therefore, a multifunctional finger rehabilitation exerciser is proposed to solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 3This utility model provides an embodiment of a multifunctional finger rehabilitation exerciser, including a wrist brace 1, which serves to fix and support the wrist, allowing the entire rehabilitation exerciser to be stably worn on the user's wrist. A connecting strap 2 is provided at the lower part of the wrist brace 1, which can be adjusted according to the user's wrist size via Velcro, further enhancing the stability of the device. A support plate 3 is fixedly connected to the upper part of the wrist brace 1, serving as the support structure for the entire device. A connecting plate 4 is rotatably connected to the front of the support plate 3, connecting the support plate 3 and a connecting plate 5. The connecting plate 5 is rotatably connected to the upper part of the connecting plate 4. Under the action of a limiting component, its relative position with the connecting plate 4 is fixed, ensuring the stability of the device structure during exercise. A tension mechanism is provided at the front of the connecting plate 5, including an adjustment component and a limiting component. The adjustment component includes a sleeve 61, which protects the internal structure, preventing damage to the compression spring 64 from external impacts and friction, extending the service life of the compression spring 64. Simultaneously, it provides sliding space for the extrusion component 62 and the threaded rod 63, ensuring the normal operation of the adjustment component.

[0032] Reference Figure 3 - Figure 5 The sleeve 61 is rotatably connected to the outside of the connecting plate 5. The inner wall of the sleeve 61 is slidably connected to the extrusion member 62. When the threaded rod 63 rotates, the extrusion member 62 will slide up and down inside the sleeve 61, thereby compressing or releasing the compression spring 64 to adjust the tension. The inner wall of the extrusion member 62 is threadedly connected to the threaded rod 63. By rotating the threaded rod 63, the extrusion member 62 is driven to move, thereby changing the degree of compression of the compression spring 64 to adjust the tension. The threaded rod 63 is slidably connected to the inner wall of the sleeve 61. The lower part of the extrusion member 62 is elastically connected to the inner wall of the sleeve 61 through the compression spring 64 to provide elastic tension. Its degree of compression or extension determines the tension applied to the finger by the finger sleeve 67.

[0033] Furthermore, a fixing member 65 is fixedly connected to the outer side of the compression spring 64. The fixing member 65 is set in a regular hexagon, which is convenient to rotate manually or with a wrench, thereby driving the threaded rod 63 to rotate and realize the adjustment of the tension. A connector 66 is rotatably connected to the lower outer side of the compression spring 64, which is used to connect the compression spring 64 and the finger sleeve 67, and transmits the tension of the compression spring 64 to the finger sleeve 67, which then acts on the finger. At the same time, it can rotate to adapt to the patient's finger. The finger sleeve 67 is set on the outer side of the connector 66 and is worn on the finger. It is connected to the compression spring 64 through the connector 66, and transmits the tension to the finger, so that the finger is exercised during the stretching process.

[0034] Reference Figure 1 and Figure 3The limiting component includes a limiting member 41, which is slidably connected to the inner wall of the connecting plate 4. There are two sets of limiting members 41. When the limiting members 41 are inserted into the inner wall of the slot 43, they can restrict the relative rotation between the connecting plate 5 and the connecting plate 4, ensuring the stability of the device structure during exercise. When the device is not in use, pulling the two sets of limiting members 41 will allow them to slide out from the inner wall of the slot 43, releasing the fixation of the connecting plate 5 and the connecting plate 4, making it convenient for the device to be folded and stored. A return spring 42 is provided on the opposite side of the two sets of limiting members 41, which allows the two sets of limiting members 41 to be stably inserted into the inner wall of the slot 43 through elastic force. The connecting plate 5 and the support plate 3 have slots 43 on their outer sides, with multiple sets and an angle of 90 degrees, providing insertion positions for the limiting members 41, realizing the function of limiting and fixing the rotation of the connecting plate 5 and the connecting plate 4. The limiting members 41 are inserted into the inner wall of the slot 43.

[0035] Furthermore, the adjustment components are set in five groups. A rotating rod 7 is rotatably connected to the upper part of the support plate 3. A sleeve 61 is set on the outside of the rotating rod 7 for exercising the patient's thumb. By rotating the rotating rod 7, the patient's left and right hands can be exercised. A stop bar 8 is set near the front of the rotating rod 7 on the support plate 3 to limit the rotation range of the rotating rod 7. There are two sets of stop bars 8. Velcro is set on the outside of the finger sleeve 67 and the outside of the connecting strap 2, which can be adjusted in length according to the patient's finger condition. The finger sleeve 67 and the connecting strap 2 are made of nylon, which has good wear resistance, breathability and flexibility, and is comfortable and durable to wear.

[0036] Working principle: During use, the fixing part 65 is rotated manually or with the aid of a wrench, according to the patient's finger rehabilitation and exercise needs. The fixing part 65 is hexagonal, which facilitates the application of force and rotation. It drives the threaded rod 63 connected to it to rotate, and the squeezing part 62 will move up and down in the sleeve 61. The movement of the squeezing part 62 will squeeze or relax the compression spring 64, thereby changing the degree of compression of the compression spring 64. Finally, the tension applied to the finger sleeve 67 can be precisely adjusted. There are five sets of adjustment components, each corresponding to one of the five fingers. The exercise intensity of each finger can be adjusted independently to adapt to the rehabilitation needs of different fingers.

[0037] When the exercise is finished or the exercise equipment needs to be stored, pull the two sets of limiting parts 41 to overcome the elastic force of the return spring 42 and slide out from the inner wall of the slot 43, releasing the fixation of the connecting plate 2 5 and the connecting plate 1 4. At this time, the device can be folded to reduce the space occupied and make it easy to carry and store.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
