Abstract
Description
Technical Field
[0001] This utility model relates to the field of rehabilitation training equipment, and in particular to a multifunctional shoulder joint rehabilitation aid. Background Technology
[0002] After a shoulder injury, using assistive devices can limit excessive shoulder joint movement, preventing re-injury during rehabilitation due to improper movements or excessive force. This provides a relatively stable environment for shoulder healing. Arm raising exercises are an important part of shoulder rehabilitation, effectively mobilizing the shoulder joint in all directions, including flexion, extension, adduction, abduction, internal rotation, and external rotation. This helps maintain and increase the range of motion of the shoulder joint, prevents joint stiffness and adhesions, maintains good flexibility and agility, and restores normal joint function.
[0003] A search revealed Chinese Patent Publication No. CN222266050U, which discloses a shoulder joint rehabilitation trainer. Through adjustable components such as a seat lifting column and a shoulder pressure width adjustment linkage, the trainer can be adjusted according to individual user differences, ensuring personalized and comfortable training. Simultaneously, it employs an adjustable bidirectional damping cylinder, allowing users to adjust the resistance level according to their needs, achieving rehabilitation training of varying intensities. This results in higher rehabilitation effectiveness and practicality, providing a more effective rehabilitation solution for patients with shoulder problems.
[0004] In the above-mentioned technical solution, shoulder joint rehabilitation training is carried out through the combination of shoulder pressure sponge and handle. However, the distance between the handle and shoulder pressure sponge cannot be adjusted. If the handle is higher than the shoulder pressure sponge, the user's arm will be raised too high.

The end of the support shaft 7 is rotatably connected to the moving shaft 8 via a pivot. A handle 9 is provided on the inner surface of the moving shaft 8. Two sets of moving shafts 8 and handles 9 are provided, and they are mirror images of each other with the central axis of the lifting column 6 as the axis of symmetry. The two sets of handles 9 are for the user to hold with both hands. A guide rail 10 is provided at the bottom of the moving shaft 8. A slide block 11 is slidably connected to the inner wall of the guide rail 10. The bottom of the slide block 11 is also rotatably connected to the telescopic cylinder 16 via a pivot. A magnetic base 13 is fixedly connected to the bottom end of the telescopic cylinder 16. A spring 15 is fixedly connected to the bottom end of the magnetic base 13. A magnetic force is fixedly connected to the bottom end of the spring 15. The second magnetic base 14, magnetic base 13, and magnetic base 2 14 are configured to be electromagnetized. After being energized, the magnetism on opposite sides of magnetic base 13 and magnetic base 2 14 is mutually repulsive. Magnetic base 13 and magnetic base 2 14 are powered by an external power supply device. The mutual repulsion strength between magnetic base 13 and magnetic base 2 14 is switched by the power supply intensity. A fixed cylinder 12 is fixedly connected to the outer wall of magnetic base 2 14. The inner wall of the fixed cylinder 12 is slidably connected to the outer wall of the telescopic cylinder 16. When both hands hold the two sets of grip rods 9, the shoulder joints move up and down. At this time, the telescopic cylinder 16 can move back and forth in the fixed cylinder 12. A fixed plate 27 is fixedly connected to the top of the lifting column 6. A hydraulic cylinder 28 is fixedly connected to the top of 27. An installation ring 29 is fixedly connected to the output end of the hydraulic cylinder 28. The hydraulic cylinder 28 controls the height of the two sets of grip rods 9. The inner wall of the installation ring 29 is fixedly connected to the inner wall of the support shaft 7. The support shaft 7 slides inside the adjustment groove 30 through the second set of adjustment seats 31. The support shaft 7 and the second set of adjustment seats 31 are fixedly connected. An adjustment groove 30 is opened on the outer wall of the lifting column 6. An adjustment seat 31 is slidably connected to the inner wall of the adjustment groove 30. The two sets of adjustment seats 31 are connected by a rigid rod to ensure the distance between the support shaft 7 and the fixed cylinder 12. The bottom end of the fixed cylinder 12 is also rotatably connected to the outer wall of the adjustment seat 31 through a rotating shaft.
[0032] Reference Figures 2-4The outer wall of the moving shaft 8 is provided with a limiting component, which includes a through groove 21. The through groove 21 is formed on the outer wall of the lifting column 6. A lead screw 23 is threadedly connected to the inner wall of the through groove 21. A knob 22 is fixedly connected to the top end of the lead screw 23. An installation rod 24 is threadedly connected to the outer wall of the lead screw 23 through a threaded block.

The limiting plate 26 is U-shaped. There are two sets of adjusting rods 25 and two sets of limiting plates 26. Furthermore, the limiting plate 26 is set in a mirror image with the center point of the adjusting rod 25 as the axis of symmetry. The limiting plate 26 is set in a U-shape and can adapt to the curvature of the shoulder, providing a certain limit to prevent active or excessive shoulder shrugging during rehabilitation exercises. The height of the two sets of limiting plates 26 is adjusted by rotating the screw 23 controlled by the knob 22. The hydraulic cylinder 28 drives the support shaft 7 to rise and fall so that the position of the grip 9 is lower than the position of the limiting plate 26, avoiding the risk of secondary injury to the shoulder joint caused by the user's inability to raise their arm in the early stage of rehabilitation.
[0033] Reference Figures 1-3 The inner wall of the movable shaft 8 is provided with a mounting groove 17, and an annular seat 18 is slidably connected to the inner wall of the mounting groove 17. The end of the annular seat 18 is fixedly connected to the end of the grip 9. The outer wall of the movable shaft 8 is provided with a through screw hole 19. Multiple sets of screw holes 19 are provided at equal intervals on each movable shaft 8. The annular seat 18 is fixed by bolts 20 through the screw holes 19 at different positions, which can switch the distance between the grip 9 and the movable shaft 8, so as to adjust for different users' arm spans. The inner wall of the screw hole 19 is threaded with a bolt 20, and the outer wall of the bolt 20 is threaded with the inner wall of the annular seat 18. The outer wall of the grip 9 is detachably connected with a sponge sleeve 32. The sponge sleeve 32 is connected to the grip 9 by nano double-sided adhesive. When replacing the sponge sleeve 32, the sponge sleeve 32 can be directly torn off, and the nano double-sided adhesive leaves no adhesive residue. The sponge sleeve 32 increases the comfort of the hand holding the grip 9.
[0034] Working principle: The user can easily move the entire assist device to a suitable position by moving the four sets of self-locking casters at the bottom of the base 1. After fixing it, the user sits on the seat connected to the support column 2 via the bracket. Then, turning the dial ring 3 drives the screw 4 to rotate. Since the screw 4 is threadedly connected to the inner wall of the lifting column 6, and the limiting rod 5 restricts the rotation of the lifting column 6, the lifting column 6 can be smoothly raised and lowered along the inner wall of the support column 2. After adjusting to a suitable height, stop. Turning the knob 22 causes the lead screw 23 to rotate, driving the mounting rod 24 and the connected adjusting rod 25 and limiting plate 26 to rise and fall. After adjusting to a suitable height, the U-shaped limiting plate 26 fits against the shoulder, restricting excessive shoulder shrugging and avoiding secondary injury caused by the inability to raise the arm in the early stages of rehabilitation. When the user holds the grip bar 9 with both hands to perform shoulder joint up and down movement training, the user moves... The shaft 8 slides along the guide rail 10, and the telescopic cylinder 16 reciprocates within the fixed cylinder 12. By controlling the power supply intensity of the magnetic base 13 and the magnetic base 14, the mutual repulsion magnetic strength between them is changed, thereby adjusting the training resistance. At the same time, the hydraulic cylinder 28 can precisely control the height of the support shaft 7 and the grip bar 9. The support shaft 7 slides in the adjustment groove 30 through the second set of adjustment seats 31, which can adjust the horizontal position of the grip bar 9 to meet the needs of various training movements and adapt to different training stages. In addition, according to the user's arm span, the ring seat 18 can slide in the mounting groove 17 of the moving shaft 8 and be fixed with bolts 20 through the screw holes 19 at different positions to adjust the distance between the grip bar 9 and the moving shaft 8. The sponge sleeve 32 on the outer wall of the grip bar 9 is fixed with nano double-sided adhesive, which can increase the grip comfort and facilitate replacement.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
