Description

Technical Field

[0001] This utility model relates to the field of rehabilitation medicine technology, specifically to an upper limb rehabilitation device. Background Technology

[0002] Upper limb motor function includes the movement of joints such as the shoulder, elbow, wrist, and hand, as well as muscle strength and coordination. After certain diseases or injuries, such as stroke, nerve damage, or fractures, upper limb muscle strength weakens, joint range of motion is limited, and motor coordination deteriorates. Rehabilitation training can specifically target these aspects, strengthening muscles, expanding joint range of motion, improving hand-eye coordination and accuracy, thereby improving overall upper limb motor function.

[0003] Some existing upper limb exercise devices have ropes set to a specific length and an integrated, fixed structure, which makes it difficult to adapt to the diverse needs of people with different heights and arm spans. In actual use, for example, for users who are taller and have longer arm spans, the limited rope length may prevent them from achieving a full range of motion when performing upper limb traction and stretching exercises. Their arm extension is restricted, making it difficult to exert force effectively, which in turn affects the exercise effect. Utility Model Content

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: an upper limb rehabilitation device, including a support frame 10 and an adjustment frame 12. The top of the support frame 10 is symmetrically fixed with two positioning frames 11. Both ends of the adjustment frame 12 are slidably connected to the adjacent positioning frames 11. The top of the adjustment frame 12 is slidably connected with a card seat 13. A steel wire rope 131 is movably engaged inside the card seat 13. Both ends of the steel wire rope 131 are fixed with grip sleeves 132.

[0023] In practice, the support frame 10 limits the lateral sliding of the limiting frame 103 and the seat cushion 104, allowing the position of the seat cushion 104 to be adjusted as needed. After the position of the seat cushion 104 is determined, the docking frame 105 is quickly limited by engaging the slot 101. Lifting the docking frame 105 releases the limitation. The height of the control frame 12 and its components is adjusted by the two positioning frames 11, thus accommodating different user heights and arm spans. The height of the control frame 12 is quickly limited by rotating the fixing screw 111 into the slot 121.

[0024] After aligning the insertion rod 1372 with the positioning plate 122, the insertion rod 1372 can be inserted into the positioning plate 122 to fix the position of the card seat 13, so that the two grips 132 can be used to rehabilitate the arm. For example, the action of alternately pulling the two grips 132 requires the card seat 13 to be in a fixed state.

[0025] The horizontally sliding seat 13 brings the fixing frame 138 close to the hanging plate 142. Then, the two hooks on the hanging plate 142 are manually connected to the fixing frame 138. The seat cushion 104 is moved horizontally away from the vertical plate 14. The user can sit on the seat cushion 104 and stretch the seat 13 using the two grips 132. The user is pulled by the restoring action of the two springs 141, thereby exercising the user's upper limbs. The vertical plate 14 is engaged with the control frame 12 and fixed with two bolts. The model of the vertical plate 14 and the springs 141 can be changed according to the user's strength requirements to produce different pulling forces for exercise and rehabilitation as needed.

[0026] See Figure 1-3 Both ends of the support frame 10 are fixedly connected to support pipes 102;

[0027] The top of the support frame 10 is provided with multiple slots 101 at equal intervals. The support frame 10 is internally connected to a limit frame 103. A cushion 104 is fixedly connected to the top of the limit frame 103. A docking frame 105 is slidably sleeved on the outer wall of the limit frame 103. The docking frame 105 can be movably engaged with the adjacent slots 101. A retaining ring 106 is fixedly sleeved on the outer wall of the limit frame 103. A spring 107 is fixedly connected between the docking frame 105 and the retaining ring 106.

[0028] Multiple slots 121 are provided at equal intervals on both sides of the control frame 12. Fixing screws 111 are screwed and connected to the opposite sides of the two positioning frames 11. The fixing screws 111 can be movably engaged with the adjacent slots 121. Protective frames 112 are fixedly connected to the opposite sides of the two positioning frames 11.

[0029] In specific implementation, the support frame 10 is enhanced by two support tubes 102. The support frame 10 limits the lateral sliding of the limiting frame 103 and the seat cushion 104. The position of the seat cushion 104 can be adjusted as needed. After the position of the seat cushion 104 is determined, the docking frame 105 is quickly limited by engaging the slot 101. Lifting the docking frame 105 can release the limitation. The height of the control frame 12 and its components is adjusted by two positioning frames 11 to accommodate the height and arm span of different users. The height of the control frame 12 is quickly limited by rotating the fixing screw 111 into the slot 121.

[0030] See Figure 1-4 The bottom of the card holder 13 is rotatably connected to four rollers 133;

[0031] The bottom of the card holder 13 is rotatably connected to the mounting bracket 134, and the inside of the mounting bracket 134 is rotatably connected to the pulley 135. The wire rope 131 is movably engaged inside the pulley 135.

[0032] The top of the card holder 13 is fixedly connected to the limiting seat 136. The top of the limiting seat 136 is slidably connected to the horizontal plate 137. Two springs 1371 are fixedly connected between the horizontal plate 137 and the limiting seat 136. The bottom of the horizontal plate 137 is fixedly connected to the insertion rod 1372 and the pull rod 1373. Two positioning plates 122 are fixedly connected to one side of the control frame 12. The insertion rod 1372 can be movably engaged with the adjacent positioning plate 122.

[0033] In practice, the sliding friction between the card holder 13 and the control frame 12 is reduced by the four rollers 133. The card holder 13 limits the mounting frame 134, so that the pulley 135 can automatically adjust its angle to cope with the direction and force of the drag. The horizontal movement of the card holder 13 can change its position in the control frame 12. After the insertion rod 1372 is aligned with the positioning plate 122, the insertion rod 1372 can be inserted into the positioning plate 122 to fix the position of the card holder 13. This makes it convenient to use the two grips 132 to rehabilitate the arm. For example, the action of alternately pulling the two grips 132 requires the card holder 13 to be in a fixed state.

[0034] See Figure 3-4 A fixing frame 138 is fixedly connected to one side of the card holder 13, and a vertical plate 14 is movably latched to the top of the control frame 12. Two springs 141 are fixedly connected to one side of the vertical plate 14, and a hanging plate 142 is fixedly connected to one end of the two springs 141. The hanging plate 142 can be movably latched to the fixing frame 138.

[0035] In practice, the horizontally moving seat 13 moves the fixing frame 138 close to the hanging plate 142. Then, the two hooks on the hanging plate 142 are manually connected to the fixing frame 138. The seat cushion 104 is moved horizontally away from the vertical plate 14. The user can sit on the seat cushion 104 and stretch the seat 13 using the two grips 132. The user is pulled by the reset action of the two springs 141, thereby exercising the user's upper limbs. The vertical plate 14 is engaged with the control frame 12 and fixed with two bolts. The model of the vertical plate 14 and the springs 141 can be changed according to the user's strength requirements to produce different pulling forces for exercise and rehabilitation as needed.

[0036] Working principle: The support frame 10 limits the lateral sliding of the limiting frame 103 and the seat cushion 104, which can adjust the position of the seat cushion 104 as needed. After the position of the seat cushion 104 is determined, the docking frame 105 is quickly limited by engaging the slot 101. Lifting the docking frame 105 can release the limit. The height of the control frame 12 and its components is adjusted by the two positioning frames 11, so as to accommodate the height and arm span of different users. The height of the control frame 12 is quickly limited by rotating the fixing screw 111 into the slot 121.

[0037] After aligning the insertion rod 1372 with the positioning plate 122, the insertion rod 1372 can be inserted into the positioning plate 122 to fix the position of the card seat 13, so that the two grips 132 can be used to rehabilitate the arm. For example, the action of alternately pulling the two grips 132 requires the card seat 13 to be in a fixed state.

[0038] The horizontally sliding seat 13 brings the fixing frame 138 close to the hanging plate 142. Then, the two hooks on the hanging plate 142 are manually connected to the fixing frame 138. The seat cushion 104 is moved horizontally away from the vertical plate 14. The user can sit on the seat cushion 104 and stretch the seat 13 using the two grips 132. The user is pulled by the restoring action of the two springs 141, thereby exercising the user's upper limbs. The vertical plate 14 is engaged with the control frame 12 and fixed with two bolts. The model of the vertical plate 14 and the springs 141 can be changed according to the user's strength requirements to produce different pulling forces for exercise and rehabilitation as needed.
