Description

Technical Field

[0001] The invention relates to the technical field of shoulder joint training, in particular to a shoulder joint self-stretching trainer. Background Art

[0002] The shoulder joint is the joint with the largest range of motion in the human body, but its stability is relatively poor. Therefore, rehabilitation training of the shoulder joint is particularly important. The shoulder joint self-stretching trainer is an auxiliary device used for shoulder joint rehabilitation training. It aims to help improve the range of motion of the shoulder joint and enhance the strength and stability of the shoulder muscles through self-stretching. This trainer is suitable for patients who need upper limb rehabilitation due to shoulder joint damage, hemiplegia caused by stroke, hand weakness, cervical discomfort, etc.

[0003] After searching, the Chinese patent with publication number CN220090384U discloses an upper limb stretching trainer, including a rotating wheel, a pull rope, and a main frame, wherein the rotating wheel is connected to the main frame, the pull rope is wound around the rotating wheel, and also includes a friction plate and a resistance adjustment mechanism, wherein the friction plate is attached to the rotating wheel, and the resistance adjustment mechanism includes a resistance plate and a pressure adjustment component, wherein the resistance plate is attached to the friction plate, and the pressure adjustment component is used to adjust the pressure of the resistance plate on the friction plate so that the friction plate and the rotating wheel are closely attached or separated. The resistance size can be freely adjusted to help patients with shoulder joint damage to perform shoulder joint activity training, joint traction and muscle strength training. It has a simple structure, is convenient and safe to use, has a significant training effect, and can improve the effect of the recovery of the patient's upper limb joint movement function. However, when this solution is actually used, it still has the following shortcomings:

[0004] However, in actual applications, especially for patients with hemiplegia caused by stroke, since hemiplegia caused by stroke often leads to impaired function of one side of the patient's body, one hand can move relatively normally, while the other hand is difficult to move or control independently. In this case, patients usually try to use their normal arm to drive the affected arm for training, but the problem is that the strength of the normal arm is often much greater than the training intensity required for the affected arm. This leads to the patient easily feeling tired due to excessive exertion during training, and may even cause further muscle tension or pain due to strength mismatch. Therefore, after several training sessions, the patient may find it difficult to continue due to physical overdraft or discomfort, which not only affects the continuity and regularity of the training, but also greatly weakens the actual effect of the training.

[0005] Therefore, the present application provides a shoulder joint self-stretching trainer. Summary of the invention

[0060] like Figures 1 to 6As shown, a shoulder joint self-stretching trainer comprises a fixed frame 1; a fixed pulley 2, rotatably mounted on the inner wall of the fixed frame 1; an L-shaped plate 3, fixedly mounted on the side of the fixed frame 1; a clamping mechanism, arranged on the L-shaped plate 3; a support frame 5, arranged at a position directly below the fixed frame 1; a movable pulley 6, rotatably mounted on the inner wall of the support frame 5, the diameter of the fixed pulley 2 being at least larger than the diameter of the movable pulley 6; a fixed hook ring 7, fixedly mounted on the inner wall of the fixed frame 1 and located directly below the fixed pulley 2; a training rope 8, one end of which is fixedly mounted on the fixed hook ring 7, and the other end of which passes around the movable pulley 6 and the fixed pulley 2 in sequence; a connecting mechanism, arranged at a relative position between the fixed frame 1 and the support frame 5; a winding box 10, fixedly mounted on the bottom surface of the support frame 5; a winding assembly, arranged on the inner side of the winding box 10;

[0061] When in use, firstly, the fixing frame 1 can be fixed to the door panel or other positions through the clamping mechanism and the L-shaped plate 3. The clamping mechanism can be used for fixed positions of different thicknesses, which is more convenient to use. After the fixing frame 1 is fixed, for normal use, the training rope 8 can be directly passed through the fixed pulley 2, and the patient can perform shoulder joint stretching training by reciprocatingly dragging the two ends of the training rope 8. If it is used for patients with hemiplegia caused by stroke, the supporting frame 5 can be removed from the fixing frame 1 through the connecting mechanism, and one end of the training rope 8 can be fixed to the fixed hook ring 7, and the other end can be passed around the movable pulley 6 and the fixed pulley 2 in turn to form a pulley group. The patient's normal arm can hold the end of the training rope 8, and the other inconvenient arm can be held against the lower part of the winding box 10, so that the normal arm can drive the inconvenient arm to form effort-saving training, making the patient more relaxed during the training process and less likely to feel tired.

[0062] like Figure 2 , Figure 3 As shown, the clamping mechanism includes: a guide opening 41, which is opened on the top surface of the L-shaped plate 3; a slide plate 42, which is slidably installed on the inner side wall of the guide opening 41; a clamping plate 43, which is fixedly installed on the bottom surface of the slide plate 42, and the top surface of the clamping plate 43 is in contact with the bottom surface of the L-shaped plate 3, and the side opposite to the L-shaped plate 3 is provided with anti-slip grooves; a fixed plate 44, which is fixedly installed on the top surface of the L-shaped plate 3 and located at the side of the guide opening 41; an adjusting screw 45, which is penetrated and arranged on the side of the fixing plate 44, and the adjusting screw 45 is screwed to the penetration, and the end of the adjusting screw 45 is rotatably connected to the side of the slide plate 42, and the end of the adjusting screw 45 is fixedly installed with a knob;

[0065] When removing the support frame 5 for use of the movable pulley 6, it is first necessary to pull the two clamps 94 in opposite directions to separate the magnetic piece 1 91 and the magnetic piece 2 93 from the inner wall of the clamp 94, and then the support frame 5 can be directly removed from the fixing frame 1 for use. When storing the two, the support frame 5 can be placed on the bottom surface of the fixing frame 1, and the two can be adsorbed and fixed under the action of the magnetic piece 1 91 and the magnetic piece 2 93, and the support frame 5 is installed more firmly with the cooperation of the positioning column 92 and the positioning groove, and then the clamp 94 can be slidably sleeved on the outside of the magnetic piece 1 91 and the magnetic piece 2 93 to achieve fixation for storage.

[0066] like Figure 4 , Figure 5 , Figure 6As shown, the winding assembly includes: a rotating shaft 111, which is rotatably mounted on the inner wall of the winding box 10; a winding disk 112, which is fixedly mounted on the outer wall of the rotating shaft 111, and an adjusting rope 13 is arranged on the inner side of the winding disk 112, and the end of the adjusting rope 13 away from the winding disk 112 passes through the winding box 10, and the end of the adjusting rope 13 located outside the winding box 10 and the end of the training rope 8 away from the fixed hook ring 7 are fixedly mounted with a training handle 14; a torsion spring 113, which is mounted on one end of the rotating shaft 111, and the two ends of the torsion spring 113 are respectively fixedly connected to the rotating shaft 111 and the inner wall of the winding box 10; a plurality of limiting teeth 114, which are The circular array is fixedly installed on the outer wall of the winding disk 112; the pull rod 115 is set through the outer wall of the winding box 10, and the pull rod 115 is slidably connected to the penetration; the connecting plate 116 is fixedly installed on the end of the pull rod 115 located on the inner side of the winding box 10, and the end of the pull rod 115 away from the connecting plate 116 is fixedly installed with the pull plate 12; the fixed teeth 117 are fixedly installed on the side of the connecting plate 116, and the fixed teeth 117 are meshed with the limiting teeth 114; the spring 118 is sleeved on the pull rod 115, and the two ends of the spring 118 are fixedly connected to the pull rod 115 and the inner wall of the winding box 10 respectively;

[0067] The position of the training handle 14 connected to the support frame 5 can be adjusted according to the patient's usage. During adjustment, the pull plate 12 can be pulled to drive the pull rod 115 to slide outward, so that the fixed teeth 117 are separated from the limiting teeth 114 on the winding disk 112, and the limit of the winding disk 112 is released. At this time, the adjustment rope 13 can be pulled to adjust its length outside the winding box 10. After the adjustment is completed, the pull plate 12 can be loosened, and under the action of the spring 118, the pull rod 115 slides in the opposite direction, and the fixed teeth 117 can be engaged with the limiting teeth 114 to fix the winding disk 112, so that it can be used stably.
