[0020] This utility model provides an upper limb rehabilitation exercise device, including a body, a main body, a support plate 100 (the body and main body are prior art and are not shown in the figure), and a fixing component. The fixing component includes a mounting rail 101, a driving component, a movable shell 102, a mounting base 103, a fixing strap 104, and an adjusting component. The driving component includes a sliding block 105, a mounting seat 106, a threaded rod 107, and a limiting element. The limiting element includes a spring 108 and an abutment plate 109. The adjusting component includes a mounting cylinder 110 and an extension rod 111. The fixing component also includes a connecting seat 112 and a flexible plate 113. This solution solves the problem that in actual use, the arm needs to be fixed to the support plate 100 by the fixing strap 104. However, when one person uses it, it is inconvenient to fix the fixing strap 104 to both arms, thus reducing the practicality of the device.

[0021] In this specific embodiment, the support plate 100 is connected to the machine body via the main body. The main body drives the support plate 100 to rotate. Both the machine body and the main body are body support components and drive components described in the existing patent technology CN221357569U, a shoulder joint rehabilitation exercise device. The support plate 100 is mounted on the machine body via the main body, and the main body drives the support plate 100 to move, thereby exercising the shoulder joint. This provides a more convenient, effective, and comfortable option for shoulder joint rehabilitation exercises. This solution makes it easier to fix the arm on the support plate 100, thereby improving the practicality of the device.

[0022] The mounting rail 101 is fixedly connected to the support plate 100 and is located on the side of the support plate 100 away from the machine body. The movable shell 102 is connected to the mounting rail 101 via the driving member, which drives the movable shell 102 to move. The mounting base 103 is fixedly connected to the movable shell 102 and is located on the side of the movable shell 102 away from the mounting rail 101. The fixing strap 104 is fixedly connected to the mounting base 103 and is located on the side of the mounting base 103 away from the movable shell 102. The adjusting member is mounted on the movable shell 102 and drives the fixing strap 104 to move. The mounting rail 101 is bolted to the bottom of the support plate 100. The movable shell 102 is connected to the support plate 100 via the mounting rail 101. The driving component is installed on the side of the mounting rail 101 away from the support plate 100. The driving component enables the movable shell 102 to move stably on the mounting rail 101. The mounting base 103 is bolted to the outside of the movable shell 102. One end of the fixing strap 104 is bolted to one side of the mounting base 103. The adjusting component is installed on the inside of the movable shell 102. The adjusting component tightens the fixing strap 104, thereby enabling the fixing strap 104 to stably fix the arm to the support plate 100. By moving the movable shell 102, the fixing strap 104 is moved above the arm, thus achieving a more convenient way to fix the arm to the support plate 100, thereby improving the practicality of the equipment.

[0023] Secondly, the sliding block 105 is slidably connected to the mounting rail 101 and located on the side of the mounting rail 101 away from the support plate 100, and is connected to the movable housing 102; the mounting base 106 is fixedly connected to the support plate 100 and located on the side of the support plate 100 close to the mounting rail 101; the threaded rod 107 is rotatably connected to the mounting base 106 and located on the side of the mounting base 106 close to the sliding block 105, and is connected to the sliding block 105; the limiting element is installed on the mounting base 106, and the limiting element restricts the movement of the sliding block 105. The sliding block 105 is slidably mounted on the mounting rail 101, and the mounting rail 101 has a groove that mates with the sliding block 105, so that the sliding block 105 can slide stably on the mounting rail 101. The side of the sliding block 105 away from the mounting rail 101 is connected to the movable housing 102 by bolts, thereby... The movable housing 102 is movable on the mounting rail 101. The mounting base 106 is bolted to the support plate 100 on the side near the mounting rail 101. The threaded rod 107 is mounted on the mounting base 106 via a bearing, allowing the threaded rod 107 to rotate on the mounting base 106. One end of the threaded rod 107 passes through the sliding block 105, enabling the threaded rod 107 to drive the sliding block 105 to move. This causes the movable housing 102 to move the fixing belt 104 above the arm. A motor is mounted on one side of the mounting base 106 to drive the threaded rod 107 to rotate. The motor drives the threaded rod 107 to rotate, causing the sliding block 105 to move the movable housing 102. A limiting element is mounted on the threaded rod 107 to limit the distance the sliding block 105 moves, thus preventing the motor from jamming and improving the service life of the equipment.

[0024] Meanwhile, the abutment plate 109 is slidably connected to the threaded rod 107 and is located on the side of the threaded rod 107 near the mounting base 106; the spring 108 is sleeved on the outside of the threaded rod 107, and the two ends of the spring 108 abut against the abutment plate 109 and the mounting base 106 respectively. The abutment plate 109 is slidably installed on the side of the threaded rod 107 near the mounting base 106, and the end of the threaded rod 107 near the mounting base 106 is not threaded, thereby making the... When the sliding block 105 moves to the position of the abutment plate 109, the threaded rod 107 can no longer drive the sliding block 105 to move. The spring 108 is sleeved on the outside of the threaded rod 107, and the two ends of the spring 108 abut against the abutment plate 109 and the mounting base 106 respectively. The spring 108 drives the abutment plate 109 to move away from the mounting base 106, so that when the threaded rod 107 rotates in the opposite direction, it can drive the sliding block 105 to move.

[0025] Additionally, the mounting cylinder 110 is fixedly connected to the movable shell 102 and is located on the side of the movable shell 102 away from the mounting rail 101; the extension rod 111 is slidably connected to the mounting cylinder 110 and is located on the side of the mounting cylinder 110 away from the movable shell 102, and is connected to the fixing strap 104. The mounting cylinder 110 is bolted to the inner side of the movable shell 102, and the extension rod 111 is slidably mounted on the mounting cylinder 110. One end of the extension rod 111 away from the mounting cylinder 110 is connected to the fixing strap 104. The extension rod 111 extends and retracts on the mounting cylinder 110 to retract and extend the fixing strap 104, thereby enabling the fixing strap 104 to stably fix the arm to the support plate 100. A hydraulic rod is installed on the inner side of the mounting cylinder 110 to drive the extension rod 111 to move, thereby enabling the extension rod 111 to stably retract and extend the fixing strap 104.

[0026] Finally, the connecting seat 112 is fixedly connected to the mounting base 103 and is located on the side of the mounting base 103 close to the fixing strap 104; the flexible plate 113 is fixedly connected to the connecting seat 112 and is located on the side of the connecting seat 112 away from the mounting base 103, and is connected to the fixing strap 104. The connecting seat 112 is installed on top of the mounting base 103 by bolts. The flexible plate 113 is made of rubber so that it can recover after bending. One end of the flexible plate 113 is fixedly installed on the connecting seat 112 by bolts. The side of the flexible plate 113 away from the connecting seat 112 is connected to the fixing strap 104, thereby allowing the flexible plate 113 to support the fixing strap 104, thus facilitating the insertion of the arm into the fixing strap 104.

[0027] Using the upper limb rehabilitation exercise device of this embodiment, after the user lies on the machine body with their arm placed above the support plate 100, the motor is started. The motor drives the threaded rod 107 to rotate, which in turn causes the sliding block 105 to move the movable shell 102, thereby positioning the fixing strap 104 above the arm. At this time, the hydraulic rod is activated to retract the extension rod 111, which in turn tightens the fixing strap 104, thus fixing the arm to the support plate 100. This achieves a more convenient way to fix the arm to the support plate 100, thereby improving the practicality of the device.
