Detailed Implementation

[0026] 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.

[0027] Please see Figures 1-5 A hand-lifting training device for stroke patients includes an arched frame 100. Annular moving parts 200 are provided on both the left and right side walls inside the arched frame 100. Pull rings 300 are fixedly installed on the upper half of each opposite side of the two annular moving parts 200, and pull rings 400 are fixedly installed on the lower half of each opposite side of the two annular moving parts 200. During stroke rehabilitation exercises, exercises are performed by pulling down on pull rings 300 or pulling up on pull rings 400. Elastic resistance members 500 are fixedly installed on the opposite sides of each annular moving part 200, providing resistance as the annular moving parts 200 move. The elastic resistance members 500 are fixedly installed on the arched frame 100, and a seat 600 is provided between the two annular moving parts 200.

[0028] Each annular moving part 200 includes two rollers 201, which are rotatably connected to the side wall of the arched frame 100. The two rollers 201 are connected by an annular belt 202. A connecting belt 1 203 is fixedly installed on the upper half of the annular belt 202 facing the center of the arched frame 100, and a connecting belt 204 is fixedly installed on the lower half of the annular belt 202 facing the center of the arched frame 100. The end of the connecting belt 1 203 away from the annular belt 202 is fixedly installed to a pull ring 300, and the end of the connecting belt 204 away from the annular belt 202 is fixedly installed to a pull ring 400. By setting the connecting belt 1 203 and the connecting belt 204, a certain distance can be maintained between the pull ring 300 and the pull ring 400 and the annular belt 202, which is convenient for use. Both connecting strap 203 and connecting strap 204 have arrayed positioning holes. The upper and lower halves of the annular belt 202 facing the center of the arched frame 100 are each provided with locking posts 205, which engage with the positioning holes. This allows connecting strap 203 and connecting strap 204 to be stored on the surface of the annular belt 202, saving space and preventing the annular belt 202 or connecting strap 203 from becoming entangled on the annular belt 202 during exercise by stroke patients.

[0029] Each elastic resistance element 500 includes a storage box 501 fixedly installed on the inner wall of the arched frame 100. Two guide rods 502 are fixedly installed between the top and bottom walls of the storage box 501. A pressure plate 503 is slidably connected to the guide rods 502. A slider 504 is fixedly installed in the middle of the pressure plate 503 facing the annular moving element 200. The slider 504 is fixedly installed on the annular moving element 200. A groove 505 is opened through the surface of the storage box 501. The slider 504 is slidably connected in the groove 505. Elastic elements are arranged in an array at the top and bottom of the pressure plate 503. Therefore, when the pull ring 300 is pulled down, the pressure plate 503 moves upward under the action of the slider 504, and the pressure plate 503 presses the elastic element on its upper side upward; as the upward distance of the pressure plate 503 increases, the resistance exerted by the elastic element on the pressure plate 503 gradually increases; similarly, when the pull ring 400 is pulled up, the pressure plate 503 presses the elastic element on its lower side downward, and the elastic element exerts resistance on the pressure plate 503.

[0030] The elastic element includes a spring 507, with insert plates 508 fixedly mounted at both ends. Spacers 506 are fixedly mounted on both side walls at the top and bottom of the storage box 501, forming receiving grooves between the spacers 506 and the top or bottom wall of the storage box 501. The insert plates 508 are inserted into these receiving grooves. Thus, the intensity of the exercise can be adjusted by increasing or decreasing the number of elastic elements inserted into the receiving grooves. The number of elastic elements located in front of the slider 504 is equal to the number of elastic elements located behind the slider 504.

[0031] Each of the two storage boxes 501 has a U-shaped baffle 510 on its opposite side. The U-shaped baffle 510 fits against the front and rear surfaces of the arched frame 100, covering the opening of the storage box 501. A threaded rod 509 is threadedly connected to the center of the U-shaped baffle 510, and the threaded rod 509 is rotatably connected to the arched frame 100. By turning the threaded rod 509, the U-shaped baffle 510 can be moved left and right. When the U-shaped baffle 510 is removed from the opening of the storage box 501, it facilitates the installation or removal of the elastic element. When the U-shaped baffle 510 covers the opening of the storage box 501, it prevents the elastic element from falling out of the opening of the storage box 501.

[0032] Two slides 601 are fixedly installed at the bottom of the seat 600, and the two slides 601 are distributed from left to right. The bottom of the slides 601 is provided with a slide rail 602. Thus, the seat 600 can move back and forth along the slide rail 602, and stroke patients can choose to exercise standing up or sitting on the seat 600.

[0033] A fixing plate 603 is fixedly installed between the front ends of the two slides 601. A rearwardly extending lug 604 is fixedly installed on the top of the fixing plate 603. An L-shaped plate 605 is provided on the front side of the fixing plate 603. The horizontal part of the L-shaped plate 605 is fixed to the lug 604 by bolts 606. This fixes the seat 600 in its current position and prevents the seat 600 from moving during exercise.

[0034] In use, by holding the pull ring 300 and pulling it laterally, part of the locking pin 205 is separated from the connecting belt 203, and the connecting belt 203 is released to a suitable length. Pulling the pull ring 300 downwards drives the annular belt 202 to move. With the connecting action of the slider 504, the pressure plate 503 is moved upwards. The pressure plate 503 squeezes the spring 507 on its upper side. As the pressure plate 503 moves upwards, the resistance exerted by the spring 507 on the pressure plate 503 gradually increases.

[0035] Similarly, you can hold it on the pull ring 2400, pull it horizontally first, and then pull it upwards to exercise;

[0036] Before exercising, the threaded rod 509 can be screwed on to move the U-shaped baffle 510 away from the opening of the storage box 501. Then, elastic elements can be added or removed inside the storage box 501 to adjust the resistance when pulling the first pull ring 300 and the second pull ring 400. Then, the threaded rod 509 can be screwed on in the opposite direction to make the U-shaped baffle 510 block the opening of the storage box 501 to prevent the elastic elements from falling out of the opening of the storage box 501.

[0037] The seat 600 can slide along the slide rail 602, allowing it to move to the area below or behind the arch frame 100. Stroke patients can rotate to sit on the seat 600 for exercise, or choose to stand for exercise. The lug 604 is connected to the L-shaped plate 605 by bolt 606 to limit the seat 600 and prevent it from moving during exercise.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
