Description

Technical Field

[0001] This utility model relates to the field of finger rehabilitation technology, specifically a finger rehabilitation exercise device. Background Technology

[0002] As the most used body part during work and exercise, the health of the hands is very important. Some patients suffer from joint stiffness due to stroke, hemiplegia, or other diseases, making it impossible for them to actively bend, clench, or open their hands. In order to prevent contractures and slow blood circulation, passive exercise training of the hand joints is necessary.

[0003] Chinese patent provides a finger rehabilitation exercise device, publication number CN212941249U, comprising: a main body; a fixing structure; a rotating shaft disposed on a first side of the main body; a pulley with a groove corresponding to the rotating shaft on one side, the groove being rotatably connected to the rotating shaft; an elastic rubber band surrounding the outer circumference of the pulley, with five elastic rubber ribs at its end; five finger rings respectively disposed at the ends of the five elastic rubber ribs; and screws sequentially passing through the connecting hole of the pulley, the second threaded hole of the rotating shaft, and the first threaded hole of the main body. In use, this utility model embodiment simply requires the finger rings to be placed on the fingers, allowing for finger exercise through the elasticity of the elastic rubber band and ribs, eliminating the need for gripping and avoiding the problem of users with gripping deficiencies being unable to use it.

[0004] Although the device is equipped with hand loops and rubber bands, which can play a certain role in rehabilitation exercises, the tension and the distance between the loops cannot be adjusted during use. This makes it unsuitable for patients to gradually adapt to different strength levels during treatment, resulting in poor exercise effects.

[0005] Therefore, there is a need to provide a finger rehabilitation exercise device. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a finger rehabilitation exercise device, comprising a mounting block and a mounting plate, wherein a ratchet mechanism is fixedly mounted on the side of the mounting plate, an adjustment mechanism is fixedly mounted on the side of the ratchet mechanism, and a pulling mechanism is fixedly mounted on the inner wall of the mounting block; the ratchet mechanism includes a housing, a connecting plate is fixedly mounted on the inner wall of the housing, a first locking block is rotatably mounted on the side of the connecting plate via a bearing seat, a fourth return spring is fixedly mounted on the side of the first locking block, a baffle is fixedly mounted on the inner wall of the housing, the side of the baffle is fixedly connected to the other end face of the fourth return spring, a second locking block is fixedly mounted on the inner wall of the housing, a through hole is fixedly opened on the side of the housing, a bearing sleeve is fixedly mounted on the inner wall of the through hole, and a connecting rod is fixedly mounted on the inner wall of the bearing sleeve.

[0008] Preferably, a rotating rod is fixedly installed on the side of the connecting rod, and a ratchet is fixedly installed on the end face of the connecting rod, with the ratchet teeth engaging with the side of the first locking block.

[0009] Preferably, a pin is rotatably mounted on the inner wall of the outer casing via a bearing seat, a lever is fixedly mounted on the side of the pin, the side of the lever is in contact with the side of the first locking block, and a lever is fixedly mounted on the end face of the pin.

[0010] Preferably, the adjusting mechanism includes a threaded rod, a threaded sleeve is threadedly installed on the side of the threaded rod, a first slider is fixedly installed on the side of the threaded sleeve, a limiting member is fixedly installed on the bottom end face of the first slider, a sliding groove is slidably installed on the side of the limiting member, and the end face of the sliding groove is fixedly connected to the side of the outer shell.

[0011] Preferably, the end face of the threaded rod is rotatably connected to the side of the mounting block via a bearing seat, a second adjustment component is fixedly installed on the side of the mounting plate, and a handle is fixedly provided on the side of the mounting block.

[0012] Preferably, a pulling mechanism is fixedly installed on the inner wall of the side of the mounting block. The pulling mechanism includes a mounting frame, the side of which is fixedly connected to the inner wall of the mounting block. A first return spring is fixedly installed on the inner wall of the mounting frame, and a first pull ring is fixedly installed on the end face of the first return spring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) When this finger rehabilitation exerciser is needed for finger rehabilitation training, grip the handle tightly, take out the device, insert the five fingers into the four first pull rings on the right side in sequence, and then insert the thumb into the second pull ring. At this time, apply force to the device, and the five fingers will pull the first pull ring and the first return spring respectively to stretch. The second pull ring will pull the second return spring and the third return spring to stretch, thus performing rehabilitation exercises for the fingers. As the exercise progresses, if it is necessary to adjust the stretching force or change the exercise posture, the second pull ring can be adjusted through the adjustment mechanism to adapt to different exercise needs, thereby improving the applicability and practicality of the device, as well as its convenience and safety.

[0016] 2) This finger rehabilitation exercise device, when the lever is turned, drives the lever block to deflect via the pin, squeezing the first locking block to deflect, and pushes the first locking block through the fourth spring to prevent the ratchet from turning back. At this time, rotating the rotating rod drives the connecting rod and the threaded rod to rotate, which in turn drives the threaded sleeve to move, which in turn drives the first slider and the limiting part to slide on the inner wall of the slide groove. Then, the second return spring, the third return spring and the second pull ring are adjusted to adjust the position, so as to adapt to different exercise needs, solving the problem that the tension and sawing of traditional exercise devices cannot be adjusted.

A lever 511 is fixedly installed on the side of the pin 510. The side of the lever 511 is pressed and connected to the side of the first locking block 503. A lever 512 is fixedly installed on the end face of the pin 510.

[0027] Specifically, when finger rehabilitation training is needed, grip handle 2, take out the device, and insert the index, middle, ring, and little fingers into the four first pull rings 303 on the right side in sequence, then insert the thumb into the second pull ring 305. At this time, apply force to the device, and the five fingers will pull the first pull ring 303 and the first return spring 302 respectively to stretch. The second pull ring 305 will pull the second return spring 304 and the third return spring 306 to stretch, thus performing rehabilitation exercises for the fingers. As the exercise progresses, when it is necessary to adjust the stretching force or change the exercise posture, turn the lever 512 to drive the lever block 511 to deflect through the pin 510, squeeze the first locking block 503 to deflect, and push the first locking block 503 through the fourth return spring 504 to prevent the ratchet 509 from turning back. At this time, turn the rotating rod 508 to drive the connecting rod 506 and the threaded rod 601 to rotate, and drive the second pull ring 305 to adjust its position to adapt to different exercise needs.
