Description

Technical Field

[0001] This utility model relates to the field of rehabilitation equipment technology, specifically to a rehabilitation hand strength training device. Background Technology

[0002] Hand surgery refers to the surgery of the hand. Because the hand is used very frequently in human labor and production, the probability of hand injury or disease will also increase accordingly. Furthermore, engaging in other work may also cause hand damage. When the finger is seriously injured, surgical rehabilitation equipment is needed for auxiliary treatment in the subsequent rehabilitation process to speed up the recovery of the finger.

[0003] Existing rehabilitation hand strength training devices typically involve the patient gripping the device and pressing a movable lever with their fingers to overcome spring resistance, thus exercising hand strength. However, this method lacks the ability to adjust the resistance of the lever, resulting in the patient applying the same amount of force throughout the exercise. Consequently, the device cannot adjust the intensity based on the patient's recovery progress, affecting its effectiveness. Therefore, there is an urgent need for a rehabilitation hand strength training device to address these issues. Utility Model Content

[0004] Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide a rehabilitation hand strength training device that can adaptively adjust the intensity of exercise according to the degree of recovery, which has good effect and strong functionality.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a rehabilitation hand strength training device, including a support base, four sets of guide cylinders arranged in an array at one end of the support base, springs installed inside the guide cylinders, a connecting rod fixed to the free end of the springs, a pad provided at one end of the connecting rod, a threaded groove opened on the outer wall of one end of the guide cylinder, six sets of dividing grooves distributed circumferentially at the end of the guide cylinder, and a threaded sleeve with a gradually decreasing inner diameter provided on the outer side of the threaded groove.

[0008] Furthermore, the end face of the support seat opposite to the guide cylinder is streamlined, and the guide cylinder is fixed to the support seat by screws.

[0009] By adopting the above technical solution, it is easier for patients to hold the support seat.

[0010] Furthermore, one end of the spring is welded inside the guide cylinder, the connecting rod is welded to the free end of the spring, and the connecting rod is slidably connected to the guide cylinder.

[0011] By adopting the above technical solution, the connecting rod can extend and retract within the guide cylinder via the spring.

[0012] Furthermore, the pad is fixed to the connecting rod by screws, and the pad has a circular structure.

[0013] By adopting the above technical solution, during the training process, the patient holds the support seat and places four fingers on the pad, and then applies pressure to the pad so that it compresses the spring through the connecting rod, thereby exercising the patient's hand by overcoming the spring's rebound force.

[0014] Furthermore, both the threaded groove and the partition groove are formed on the guide cylinder.

[0015] By adopting the above technical solution, the dividing groove can divide the part of the guide rod end that is the threaded groove into six independent parts, so that it can shrink inward under the extrusion force of the threaded sleeve.

[0016] Furthermore, the threaded sleeve is connected to the threaded groove by a thread, and the surface of the threaded sleeve is formed with a frosted texture.

[0017] By adopting the above technical solution, the screw sleeve is rotated to move under the action of the threaded groove and squeeze the part separated at the end of the guide cylinder, causing it to shrink inward. In this way, the intensity of the exercise can be adaptively adjusted according to the degree of recovery by changing the friction between the end of the guide cylinder and the connecting rod. The effect is good, and the frosted texture makes it easy to rotate the screw sleeve.

[0018] Furthermore, the support base has a rubber pad adhered to its streamlined end face.

[0019] By adopting the above technical solution, the rubber pad can ensure the comfort of the patient's hand when holding it.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] To address the problem that existing rehabilitation hand strength training devices often rely on patients gripping the device and pressing a movable rod with their fingers to overcome spring resistance, this method suffers from limitations. The inability to adjust the rod's resistance results in patients applying the same amount of force throughout the exercise, hindering the device's ability to adjust the intensity based on the patient's recovery level and thus affecting its effectiveness. This invention addresses this issue by incorporating threaded grooves, dividing grooves, and a tapering inner diameter threaded sleeve. During training, the dividing grooves separate the threaded section at the end of the guide rod into six independent parts. Rotating the threaded sleeve allows it to move under the influence of the threaded grooves, compressing the divided sections at the end of the guide cylinder and causing them to contract inwards. This alters the friction between the guide cylinder end and the connecting rod, allowing for adaptive adjustment of the exercise intensity based on the recovery level, resulting in superior performance.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] like Figures 1-3As shown, a rehabilitation hand strength training device in this embodiment includes a support base 1. Four sets of guide cylinders 2 are arrayed at one end of the support base 1. Springs 8 are installed inside the guide cylinders 2. A connecting rod 5 can extend and retract within the guide cylinders 2 via the springs 8. A connecting rod 5 is fixed to the free end of the springs 8, and a pad 6 is provided at one end of the connecting rod 5. During training, the patient holds the support base 1 with four fingers on the pad 6, and then applies pressure to the pad 6, causing it to compress the springs 8 via the connecting rods 5. By overcoming the rebound force of the springs 8, the patient's hand is exercised. 2. A threaded groove 3 is provided on the outer wall of one end. Six sets of dividing grooves 7 are distributed circumferentially at the end of the guide cylinder 2. A threaded sleeve 4 with a gradually decreasing inner diameter is provided on the outer side of the threaded groove 3. During training, the dividing groove 7 can divide the part of the guide rod end with the threaded groove 3 into six independent parts. Rotating the threaded sleeve 4 causes it to move under the action of the threaded groove 3 and squeezes the divided part of the end of the guide cylinder 2, causing it to contract inward. In this way, the intensity of the exercise can be adaptively adjusted according to the degree of recovery by changing the friction between the end of the guide cylinder 2 and the connecting rod 5.

[0030] like Figures 1-3 As shown, in this embodiment, the end faces of the support seat 1 and the guide cylinder 2 are streamlined. The guide cylinder 2 is fixed to the support seat 1 by screws. One end of the spring 8 is welded inside the guide cylinder 2. The connecting rod 5 is welded to the free end of the spring 8. The connecting rod 5 is slidably connected to the guide cylinder 2. The pad 6 is fixed to the connecting rod 5 by screws. The pad 6 has a circular structure.

[0031] like Figures 1-3 As shown, in this embodiment, the threaded groove 3 and the partition groove 7 are both formed on the guide cylinder 2. The threaded sleeve 4 is connected to the threaded groove 3 by threads. The surface of the threaded sleeve 4 is formed with a frosted texture 9. The bearing seat 1 has a rubber pad 10 bonded to its streamlined end face. The rubber pad 10 can ensure the comfort of the patient's hand when holding it.

[0032] The specific implementation process of this embodiment is as follows: During use, the patient holds the support seat 1 and places four fingers on the pad 6, then applies pressure to the pad 6 so that it compresses the spring 8 through the connecting rod 5. By overcoming the rebound force of the spring 8, the patient's hand is exercised. During the training process, since the dividing groove 7 can divide the part of the guide rod end with the threaded groove 3 into six independent parts, the screw sleeve 4 is rotated so that it moves under the action of the threaded groove 3 and squeezes the divided part of the guide cylinder 2 end, causing it to contract inward. Then, by changing the friction between the end of the guide cylinder 2 and the connecting rod 5, the intensity of the exercise can be adaptively adjusted according to the degree of recovery, thereby improving the training effect of the device.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
