Description

Technical Field

[0001] This utility model relates to the technical field of hand exercise devices, and in particular to a hand function exercise device. Background Technology

[0002] In the field of neuroscience, the recovery and training of finger function is crucial for patients' quality of life. The dexterity and precision of the fingers directly affect a patient's ability to perform daily activities, such as writing, grasping, and manipulating objects. Currently, it is essential to help patients recover finger function through exercises. Traditional finger training methods may include physical therapy and manual exercises, and the use of finger training devices is unavoidable in finger training.

[0003] For example, patent document CN222092458U discloses a finger exerciser, including an adjustable top plate, a support block fixed to the rear side of the top plate, a first exercise component mounted on the top of the support block, and four parallel grooves at the top left end of the top plate, each groove housing a second exercise component. The first exercise component includes a side plate fixedly connected to the top of the support block, a connecting rod slidably passing through the rear side of the side plate, a paddle for thumb exercise fixedly connected to one end of the connecting rod, a limit block coaxially fixed to the other end of the connecting rod, and a first spring sleeved on the connecting rod. The second exercise component includes a slider slidably connected to the grooves, with a protrusion fixed to the top of the slider. This finger exerciser, through the action of the first and second exercise components, can simultaneously exercise the thumb and the other four fingers of the hand, thereby promoting the comprehensive recovery of the patient's finger function.

[0004] However, this device can only train the active function of the fingers, and it cannot provide a good training and recovery effect for people with poor active hand function. Utility Model Content

[0005] The purpose of this invention is to provide a hand function training device to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-5 As shown, a hand function training device includes a support plate 1. A fixing mechanism is provided at the bottom of the support plate 1. The support plate 1 is also provided with a tensioning mechanism, which includes a movable plate 301. The movable plate 301 is fixedly connected to the side of the support plate 1 away from the fixing mechanism. An adjusting bolt 302 is threadedly connected to the movable plate 301. A horizontal plate 303 is threadedly connected to the top of the adjusting bolt 302. A limiting groove 304 is provided on the support plate 1. The movable plate 301 is fixedly connected to the support plate 1 by bolts passing through the limiting groove 304. A limiting mechanism is provided at the bottom of the horizontal plate 303. An adjusting mechanism is provided on one side of the support plate 1. An elastic mechanism is provided on the side of the horizontal plate 303 away from the adjusting bolt 302. Two reinforcing ribs 7 are fixedly connected to the top of the lower side of the support plate 1.

[0026] The fixing mechanism includes a fixing plate 201, which is fixedly connected to the bottom of the support plate 1. Two limiting blocks 202 are fixedly connected to the fixing plate 201. The top of the limiting blocks 202 is fixedly connected to the bottom of the support plate 1. A strap 203 passes through the bottom of the limiting blocks 202. One end of the strap 203 is fixedly connected to a Velcro 204. The Velcro 204 is removed, the forearm is passed through the strap 203, and the fixing plate 201 is fixed to the forearm.

[0027] The limiting mechanism includes two connecting blocks 401, which are fixedly connected to the top of the support plate 1. A rotating shaft 403 is connected through the connecting block 401, and two protrusions 402 are rotatably connected to the rotating shaft 403, so that the horizontal plate 303 rotates around the rotating shaft 403.

[0028] A coil spring is sleeved on the rotating shaft 403, and the coil spring inside the rotating shaft 403 will reset the horizontal plate 303.

[0029] The adjustment mechanism includes an adjustment plate 501, which is fixedly connected to the top of the lower side of the support plate 1. A secondary spring 502 is fixedly connected to the bottom of the adjustment plate 501, and a side finger sleeve 503 is fixedly connected to the other end of the secondary spring 502. The front-to-back angle between the adjustment plate 501 and the support plate 1 is adjusted to adjust the stretching stroke of the thumb and the side finger sleeve 503 relative to the secondary spring 502. The magnitude of the stretching stroke determines the resistance of the thumb when performing a grasping action.

[0030] The elastic mechanism includes a limiting plate 601, which is fixedly connected to the bottom of the horizontal plate 303 on the side away from the adjusting bolt 302. The limiting plate 601 has two sliding grooves 602 and a mating groove 603. Adjusting grooves 605 are provided on both the front and rear sides of the limiting plate 601. Two sliders 604 are fixedly connected to the limiting plate 601, and the sliders 604 are slidably connected to the inner surface of the sliding grooves 602. Four main springs 606 are fixedly connected to the bottom of the limiting plate 601, and a front finger sleeve 607 is fixedly connected to the bottom of each main spring 606. The mechanism adjusts the limiting plate 601 and the frontmost and last... The left and right positions of the rear main spring 606 and the front finger sleeve 607 are adapted to accommodate different hand sizes. By rotating the adjusting bolt 302, the vertical height of the limiting plate 601 can be adjusted, changing the extension stroke of the main spring 606 to adjust the resistance of the other four fingers when performing grasping actions. When the hand is actively and repeatedly grasping, the main spring 606 stretches to create resistance to exercise the active function of the hand. When the hand cannot perform active exercises, pressing the side of the horizontal plate 303 away from the main spring 606 will raise the other side of the horizontal plate 303, thereby lifting the fingers that are fitted into the front finger sleeve 607.

[0031] Working principle: When using this device, the operator first removes the Velcro 204, passes the forearm through the strap 203, and fixes the fixing plate 201 to the forearm. Then, the operator adjusts the front-to-back angle between the adjusting plate 501 and the support plate 1 to adjust the extension stroke of the thumb and side finger sleeve 503 relative to the auxiliary spring 502. The magnitude of the extension stroke determines the resistance of the thumb when performing a grasping action. Then, the operator adjusts the left and right positions of the limiting plate 601, the foremost and rearmost main springs 606, and the front finger sleeve 607 to accommodate different users' hand sizes. This is done by rotating the adjusting bolt 3. 02. The vertical height of the limiting plate 601 can be adjusted to change the extension stroke of the main spring 606, thereby adjusting the resistance of the other four fingers when performing grasping actions. When the hand performs active and repeated grasping exercises, the extension of the main spring 606 creates resistance to exercise the active function of the hand. When the hand cannot perform active exercises, pressing the side of the horizontal plate 303 away from the main spring 606 will raise the other side of the horizontal plate 303, thereby raising the fingers that are fitted into the front finger sleeve 607. After releasing the horizontal plate 303, the coil spring in the rotating shaft 403 will return to its original position, thus passively exercising the function of the hand.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
