[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] The utility model features an armrest mounted on a support plate that can be rotated by a motor.

The patient's arm is secured to the armrest, thereby adjusting the vertical angle between the shoulder joint and the patient's body during arm movement. Furthermore, because the angle between the support plate and the plate sleeve can be adjusted by an angle adjustment mechanism, the armrest can be moved horizontally away from or closer to the patient's body, thereby adjusting the horizontal angle between the shoulder joint and the patient's body during arm movement. Moreover, the driven gear in the present invention is detachably installed. When the driven gear is removed, the arm support is no longer driven by the motor to rotate. The patient can actively rotate his arm to train the shoulder joint. The angle of active training of the shoulder joint is limited by the angle adjustment structure and the limiting structure, and the passive shoulder joint training using the motor is changed to the patient's own active training device. The usage mode of the present invention can be adjusted according to the patient's own needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; they can refer to mechanical connection or electrical connection; they can refer to direct connection or indirect connection through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0027] Specific embodiments, as shown in the figure, are a preferred implementation manner of the present utility model. A shoulder joint rehabilitation training device mainly includes a base 1. A backboard 2 is vertically installed on the upper end surface of the base 1. A plate sleeve 4 is slidably installed on the backboard 2. The backboard 2 and the plate sleeve 4 are fixed by a fixing structure. On both sides of the front of the plate sleeve 4, support plates 6 are respectively installed. The support plates 6 are rotatably connected to the plate sleeve 4. The support plates 6 rotate around the vertical direction. An angle adjustment structure is installed between the support plates 6 and the plate sleeve 4. Rotation holes and arc-shaped sliding holes 7 are formed in the support plates 6. An armrest 5 is installed on the front of the support plates 6. A fixing belt 9 is installed on the armrest 5. On the same side of the armrest 5, a rotating rod and a sliding rod 16 are vertically installed. The rotating rod is rotatably connected in the rotation hole. The free end of the rotating rod extends out of the back of the support plate 6. A machine box 15 is installed on the back of the support plate 6. A motor is installed in the machine box 15. A driving gear is installed on the rotating shaft of the motor. A driven gear is detachably installed at the free end of the rotating rod. The driving gear and the driven gear are engaged by external gears. The driving gear and the driven gear rotate in the machine box 15. The sliding rod 16 is slidably connected in the sliding hole 7.

[0028] Further, the plate sleeve 4 is divided into a left plate sleeve and a right plate sleeve. The structures of the left plate sleeve and the right plate sleeve are the same. The outer shape structure of the left plate sleeve is in a U shape. The left plate sleeve is sleeved on the left side of the backboard 2. The left plate sleeve slides in the vertical direction. A support plate 6 is rotatably connected to the left side of the left plate sleeve. The left side here refers to the closed side of the left plate sleeve.

[0029] During specific use of the present invention, the plate sleeve 4 is slid on the backboard 2 according to the patient's height, so that the arm rest 5 on the support plate 6 on the plate sleeve 4 is adapted to the patient's height. Because the plate sleeve 4 is divided into a left plate sleeve and a right plate sleeve, the left plate sleeve and the right plate sleeve are respectively moved to the two sides of the backboard 2, and the distance between the support plate 6 and the backboard 2 is adjusted, which is suitable for patients with different arm lengths. The plate sleeve 4 and the backboard 2 are fixed by a fixing structure. Therefore, patients of different heights and arm lengths can fix their arms in the arm rest 5 when standing on the base 1 or sitting on the base 1 with a chair. When the patient needs to exercise, the angle of the support plate 6 and the plate sleeve 4 is adjusted by the angle adjustment structure to adjust the angle formed by the patient's arm and body in the horizontal direction, so that the patient can exercise at the required horizontal angle. When the patient secures their arm in the arm support 5, the motor inside the housing 15 on the back of the support plate 6 is activated. The driving gear on the motor's rotating shaft drives the driven gear to rotate. This rotation of the driven gear causes the slide bar 16 on the arm support 5 to slide around the slide hole 7. The arm support 5 rotates within the slide hole 7 around the rotating shaft, changing the vertical angle between the patient's arm and the body, thereby achieving the purpose of vertically exercising the shoulder joint. The motor provides passive training for the patient, and the motor's rotating shaft controls the number of rotations, speed, and intensity of the driving gear. The driving gear controls the rotation angle and speed of the arm support 5 within the slide hole 7 via the driven gear. The rotation angle of the arm support 5 determines the exercise angle of the shoulder joint, while the rotation speed and intensity of the arm support 5 determine the exercise intensity of the shoulder joint. Furthermore, a clamping block is mounted on the rotating shaft of the arm support 5. The clamping block is mounted on the back of the support plate 6 and is located between the support plate 6 and the driven gear. This clamping block secures the arm support 5 within the rotation hole of the support plate 6 and prevents the arm support 5 from detaching from the support plate 6.

[0030] Furthermore, the fixing structure mainly includes a fixing stud 14, one end of which is equipped with a handle for rotation; the plate sleeve 4 is provided with multiple plate holes, and the fixing studs 14 are threadedly connected to the plate holes. The ends of the fixing studs 14 abut against the back plate 2 within the plate holes. The multiple plate holes provided on the plate sleeve 4 and the multi-point fixation make the plate sleeve 4 and the back plate 2 more firmly fixed. The fixing studs 14 are threadedly connected in the multiple plate holes, and the fixing studs 14 abut against the back plate 2 within the plate holes, so that the plate sleeve 4 is clamped on the back plate 2 by the fixing studs 14, thereby achieving the plate sleeve 4 fixed to the back plate 2.

[0031] Furthermore, the fixing structure mainly includes a rod, a plurality of holes 3 are formed on the back panel 2, and a plurality of holes are formed on the panel sleeve 4. The rod is inserted into the holes 3 and the holes. The panel sleeve 4 has a plurality of holes, and the rod is inserted into the holes. The rod is inserted into the holes 3 of the back panel 2, thereby fixing the panel sleeve 4 to the back panel 2.

[0032] Furthermore, the angle adjustment structure mainly includes a first fixing block 12, a second fixing block 10, and a connecting plate 11; the first fixing block 12 is mounted on the front of the plate sleeve 4, the second fixing block 10 has a ⌚-shaped structure, and is clamped to the upper end of the support plate 6. The second fixing block 10 slides on the upper end of the support plate 6. The second fixing block 10 is provided with a fixing hole, and a fastening stud 13 is installed in the fixing hole. The end of the fastening stud 13 abuts the support plate 6 within the second fixing block 10. The upper end surface of the first fixing block 12 is flush with the upper end surface of the second fixing block 10. One end of the connecting plate 11 is rotatably connected to the first fixing block 12, and the other end of the connecting plate 11 is rotatably connected to the second fixing block 10. The angle between the support plate 6 and the plate sleeve 4 on the back plate 2 determines the horizontal angle between the patient's arm and the patient's body. When exercising, different horizontal angles have different effects on the horizontal angle of the shoulder joint exercise. When the horizontal angle of the shoulder joint exercise needs to be adjusted, the fastening stud 13 is opened and the support plate 6 is rotated so that the second fixing block 10 slides on the upper end of the support plate 6. The connecting plate 11 is rotated on the upper ends of the first fixing block 12 and the second fixing block 10. After the support plate 6 is rotated to a suitable angle, the second fixing block 10 is clamped and fixed on the support plate 6 by the fastening stud 13. The angle between the support plate 6 and the plate sleeve 4 is fixed by the connecting rod and the first fixing block 12 and the second fixing block 10.

[0033] Because exercise using a motor is passive, patients sometimes need to perform active exercises. Because the driven gear is detachably mounted on the rotating rod, when active exercise is needed, the driven gear can be removed, eliminating meshing between the driven gear and the driving gear. The driving gear no longer restricts the rotation of the rotating rod of the arm support 5, allowing the patient to perform active exercise by rotating their arm to exercise the shoulder joint. However, during active exercise, patients cannot effectively control the rotation angle of the shoulder joint. A too small rotation angle results in poor exercise effectiveness, while a too large rotation angle can easily cause shoulder injury, hindering recovery. Therefore, further, two limiting structures are detachably mounted on the sliding hole 7, and the sliding rod 16 is slidably connected to the sliding hole 7 between the two limiting structures. The limiting structure mainly includes a limiting block 17, a limiting rod 19, and a limiting nut 18. The limiting block 17 is vertically mounted with the limiting rod 19, which is inserted into the sliding hole 7. The limiting nut 18 is threadedly connected to the limiting rod 19. The limiting nut 18 and the limiting block 17 respectively abut against the front and back surfaces of the support plate 6. The two limiting structures can slide within the sliding hole 7, and the position of the limiting structures is fixed by the limiting nut 18. The sliding rod 16 of the arm support 5 slides within the sliding hole 7 between the two limiting structures. The two limiting structures are used to control the sliding angle of the sliding rod 16 of the arm support 5 within the sliding hole 7, thereby limiting the exercise angle of the shoulder joint.

[0034] In order to improve the effect of exercise, it is necessary to increase the difficulty of active exercise. Therefore, a counterweight 8 is further installed on the lower end surface of the arm support 5, and the counterweight 8 is installed at one end close to the slide bar 16. By installing counterweights 8 of different weights to increase the weight of the arm support 5, the resistance received by the patient when rotating the arm support 5 is increased, thereby achieving the purpose of exercise.

[0035] Furthermore, the upper end surface of the arm support 5 is an arc-shaped surface, and the opening of the arc-shaped surface faces upward. The patient's arm is placed in the arc-shaped surface, which can improve comfort and prevent the patient's arm from slipping out of the arm support 5.

[0036] Furthermore, the upper surface of the armrest 5 is provided with a cushion to improve comfort.

[0037] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications made under the technical spirit suggested by the present invention should fall within the scope of the patent covered by the present invention.
