When conducting children's finger dorsiflexor muscle strength rehabilitation training, finger dorsiflexor muscle strength rehabilitation trainer is usually used.

[0003] Among the existing Chinese utility models, the publication number CN220714732U discloses a child finger back extension muscle strength rehabilitation trainer, comprising a support base, a fixed rod fixedly connected to the upper side of the support base, a hand-through board fixedly connected to the upper side of the fixed rod, an adjustment component arranged on the upper side of the hand-through board, an adjustment plate arranged on the lower side of the adjustment component, a plurality of support rods of uniform distribution and the same size fixedly connected to the upper side of the adjustment plate, a suspension curved rod fixedly connected to the upper side of the support rod, an elastic rope set on the suspension curved rod, and an elastic buckle fixedly connected to the end of the elastic rope. The utility model effectively solves the problem that in actual rehabilitation training, the positions of the finger pull rings in the trainer are fixed and cannot be adjusted, and the patient can only actively adapt to the angle position of the finger pull ring, which affects the training effect, and it is also inconvenient to adjust the flexion and extension range of the patient's fingers.

[0004] Referring to the above-mentioned children's finger dorsiflexor muscle strength rehabilitation trainer, the rehabilitation trainer uses the tension of the elastic rope to train the fingers, but the elastic force of the elastic rope will decrease during the long-term stretching process, so that the tension provided by the elastic rope is reduced, resulting in a decrease in the training effect provided by the rehabilitation trainer, so that the rehabilitation trainer as a whole cannot achieve a good training effect. Therefore, how to achieve the purpose of better finger dorsiflexor muscle strength training is an important problem that needs to be solved in the design of the finger dorsiflexor muscle strength rehabilitation trainer.

[0035] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0036] like Figure 1-3 As shown, the finger dorsiflexor muscle strength rehabilitation trainer includes a finger dorsiflexor muscle strength training support frame 1, and also includes:

[0037] A guide structure 5, wherein the guide structure 5 is arranged on the finger back extension muscle strength training support frame 1;

[0038] The rehabilitation training structure 4 is arranged on a guide structure 5 , and the guide structure 5 helps to reduce the friction resistance when the rehabilitation training structure 4 moves.

[0041] The side walls on both sides of the finger dorsiflexor muscle strength training support frame 1 are arranged in an arc-shaped structure.

[0042] Avoid sharp corners that may cause injuries to children's hands.

[0043] The guiding structure 5 comprises a supporting rod 501, a fixed column 502, a roller 503, a rotating rod 504, a limiting ring groove 505 and a rotating groove 506. The supporting rod 501 is fixedly connected to the top side wall of the finger dorsiflexor muscle strength training support frame 1. The top of the supporting rod 501 is fixedly connected to the fixed column 502. A rotating groove 506 is provided on the side wall of the fixed column 502. The inner side wall of the rotating groove 506 is rotatably connected to the rotating rod 504. Four rollers 503 are equidistantly rotatably connected to the side wall of the rotating rod 504. A limiting ring groove 505 is provided on the side wall of the roller 503.

[0044] The pull rope 402 moves. When the pull rope 402 moves, the roller 503 rotates, so that the moving friction of the pull rope 402 is converted into rolling friction, thereby effectively reducing the friction resistance when the pull rope 402 moves.

[0045] A fixing frame 511 is fixedly connected to the top side wall of the fixing column 502 .

[0046] The top side wall of the fixing frame 511 overlaps with the top side wall of the roller 503 .

[0047] The fixing frame 511 can prevent the pulling rope 402 from being separated from the limiting ring groove 505 .

[0048] The rehabilitation training structure 4 includes a finger ring 401, a pulling rope 402, a movable plate 403 and a protective cover 404. The movable plate 403 is slidably connected to the support rod 501. Four pulling ropes 402 are fixedly connected to the side wall of the movable plate 403 at equal distances. The other end of the pulling rope 402 is fixedly connected to the finger ring 401. The protective cover 404 is fixedly connected to the outer wall of the finger ring 401.

[0049] The child puts his hand into the finger dorsiflexor muscle strength training support frame 1, puts his finger into the finger ring 401, and then performs grasping action training. The finger ring 401 moves under the action, and the finger ring 401 drives the pulling rope 402 to move. The pulling rope 402 pulls the moving plate 403, and the moving plate 403 is affected by the gravity of the weight, so that the child's finger needs to use a certain force to drive the moving plate 403 to move upward, thereby achieving the purpose of finger dorsiflexor muscle strength training.

[0050] The pulling rope 402 is overlapped in the limiting ring groove 505 .

[0051] The rehabilitation training structure 4 includes a clamping frame 411, a clamping pad 412, a fixed plate 413, a spring 1 414, a sliding rod 415, a spring 2 416 and a sliding sleeve 417. The fixed plate 413 is fixedly connected to the side wall of the movable plate 403. The sliding rod 415 is fixedly connected to the side wall of the fixed plate 413. The sliding sleeve 417 is slidably connected to the sliding rod 415. The spring 1 414 is fixedly connected between the sliding sleeve 417 and the fixed plate 413. The spring 2 416 is fixedly connected between the sliding rod 415 and the sliding sleeve 417. The end of the sliding sleeve 417 is fixedly connected to the clamping frame 411. The clamping pads 412 are fixedly connected to the side walls on opposite sides of the clamping frame 411.

[0052] The arc-shaped protrusion on the clamping frame 411 is separated on both sides under the action of the thrust of the weight, and the weight moves between the clamping pads 412. The sliding sleeve 417 slides on the sliding rod 415, and the spring 1 414 and the spring 2 416 are compressed. The elastic force generated by the compression of the spring 1 414 and the spring 2 416 pushes the clamping pad 412 in the opposite direction, so that the clamping pad 412 is tightly against the weight, thereby better fixing the weight.

[0053] One side of the clamping frame 411 protrudes outward in an arc shape.

[0054] When the utility model is used for rehabilitation training, a weight of appropriate weight can be placed on the movable plate 403, and the weight is pushed when placed. The arc-shaped protrusion on the clamping frame 411 is separated on both sides under the action of the weight thrust, and the weight moves into between the clamping pads 412. The sliding sleeve 417 slides on the sliding rod 415, and the spring 1 414 and the spring 2 416 are compressed. The elastic force generated by the compression of the spring 1 414 and the spring 2 416 pushes the clamping pad 412 in the opposite direction, so that the clamping pad 412 is tightly against the weight, and the weight is fixed well. The child puts his hand into the finger back extension muscle strength training support frame 1, and after the finger is sleeved in the finger sleeve ring 401, the grasping action training is carried out;

[0055] The finger ring 401 moves during the action, and the finger ring 401 drives the pulling rope 402 to move. When the pulling rope 402 moves, the roller 503 rotates, so that the moving friction of the pulling rope 402 is converted into rolling friction, thereby effectively reducing the friction resistance of the pulling rope 402 when it moves, thereby reducing the possibility of damage to the pulling rope 402. The pulling rope 402 pulls the moving plate 403, and the moving plate 403 is affected by the gravity of the weight, so that the child's fingers need to use a certain force to drive the moving plate 403 to move upward, thereby achieving the purpose of finger dorsiflexion muscle strength training. As the training stage proceeds, the weight of the weight can be appropriately increased according to the training effect, thereby achieving a better training purpose and facilitating better finger dorsiflexion muscle strength training.
