[0003] The existing arm rehabilitation training device has three main structures, the first being a structure for fixing the upper arm, the second being a structure for fixing the wrist or lower arm, and the third being a support structure for connecting the above two main structures. The user can perform self or assisted elbow bending and stretching training after wearing the device. In self elbow bending and stretching training, the drive motor of the arm rehabilitation training device needs to be turned off, and the user bends and stretches the arm by his own strength. In assisted training, the user bends and stretches the arm by the drive motor. Regardless of the training method, the user's arm needs to be restrained to fix the device on the arm and ensure the stability of the rehabilitation device. However, in actual use, the user's arm is restrained by a restraint belt or an air bag, which hinders the blood circulation of the arm after the arm is restrained.

[0048] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0049] like Figures 1 to 23 As shown in the embodiment of the present invention, an arm rehabilitation training device includes a support member 1. A pair of fixing members 11 are fixedly connected to both sides of the support member 1. A motor is installed inside the fixing member 11. A turntable 12 is fixedly connected to the output end of the motor. A curved arm frame 13 is fixedly connected to the side of the turntable 12. A limiting component 14 is fixedly connected to the end of the curved arm frame 13 away from the turntable 12. A limiting support frame 15 is fixedly connected to the top of the support member 1. A restraining airbag 16 is fixedly connected to the bottom end of the limiting support frame 15. An elbow support member 17 is fixedly connected to the end of the support member 1 near the limiting component 14.

[0050] The support member 1 is arc-shaped. A first notch 2 is provided at the center of the upper arc surface of the support member 1. A pair of second notches 20 are symmetrically provided on the upper arc surface of the support member 1 based on the first notch 2. A pair of hydraulic cylinders 21 are fixedly connected inside the first notch 2. A receiving frame 22 is fixedly connected to the output end of the hydraulic cylinder 21. The bottom end of the receiving frame 22 is inserted into the second notch 20. A placement plate 23 is fixedly connected to the top end of the receiving frame 22. The top end of the placement plate 23 is set as an inward arc shape. The inward arc shape is used to place the user's upper arm.

[0051] The existing arm rehabilitation training equipment, when in use, binds the user's arm through a binding belt or an air bag. After the user's arm is bound, the blood circulation of the arm is hindered. When the blood circulation of the arm is not smooth for a long time, the user will feel uncomfortable and the arm will be easily injured again. Therefore, the binding of the arm needs to be released every certain period of time to restore the blood circulation of the arm, which reduces the training efficiency of the user's arm and is inconvenient because the binding and relaxation of the arm are continuously performed during the training process. To solve the above problems, the embodiment of the present application is provided with a placement plate 23, a hydraulic cylinder 21 and other structures. The specific use process is as follows: when the arm rehabilitation training is performed, the user passes the arm between the placement plate 23 and the binding air bag 16 in the support 1, and then places the wrist in the limiting assembly 14. The limiting assembly 14 is used for fixing the wrist of the user. Specifically, the wrist of the user is fixed through the support structure and the binding belt. At this time, the upper arm of the user is placed in the arc surface at the top end of the placement plate 23, and the elbow is supported by the elbow supporting piece 17. Specifically, the elbow supporting piece 17 is composed of a support structure and a supporting structure and is used for supporting the elbow of the user.

[0052] The upper arm of the user is located below the binding air bag 16. The top end of the binding air bag 16 is communicatively provided with a pipeline for inflation. When in use, the air pump outside the pipeline inflates the binding air bag 16. When the binding air bag 16 expands, it downwardly presses the upper arm of the user to fix the upper arm of the user at the top end of the placement plate 23. Then, when the auxiliary curved arm and arm stretching training is performed, the motor in the driving fixing piece 11 is driven. The motor drives the rotating disc 12 to rotate. The rotating disc 12 drives the curved arm frame 13 to rotate relative to the support 1. The curved arm frame 13 drives the limiting assembly 14 to fix the wrist curved arm. Then, the curved arm frame 13 is controlled to reset and rotate. The curved arm frame 13 drives the wrist of the user to reset and move. Once the curved arm and arm stretching are completed, the above process is repeated to continuously perform the curved arm and arm stretching training. When the training is performed for a period of time, the blood circulation of the arm of the user needs to be dredged. At this time, the hydraulic cylinder 21 drives the receiving frame 22 to move downward relative to the support 1. The receiving frame 22 drives the top end of the placement plate 23 to synchronously move. The position of the placement plate 23 relative to the binding air bag 16 is increased. Therefore, the binding air bag 16 is subjected to reduced extrusion force. The extrusion force of the binding air bag 16 on the top end of the placement plate 23 is reduced. In turn, the degree of binding of the upper arm of the user is reduced, that is, the relaxation of the upper arm is realized, and the smoothness of the blood circulation is improved. At this time, the user needs to keep the arm horizontal or place the arm on the desktop to prevent the device from sliding on the arm due to the weakened binding force of the device on the arm. The curved arm and arm stretching process can continue.

[0053] Based on the above, the embodiment of the present application sets the hydraulic cylinder 21 and the restraint air bag 16; the restraint air bag 16 fixes the user's arm at the top end of the placement plate 23 during use, and when the training is carried out for a period of time, the user's arm needs to be unblocked for blood circulation, at which time the hydraulic cylinder 21 is automatically started to drive the placement plate 23 to move downward, so that the restraint air bag 16 reduces the extrusion force on the user's arm at the top end of the placement plate 23, thereby reducing the restraint degree of the user's arm, that is, realizing the relaxation of the arm, improving the smoothness of blood circulation, solving the problem that the user needs to release the restraint of the arm and restore the blood circulation of the arm every period of time, resulting in reduced training efficiency and inconvenient use, and achieving the effect of continuously and automatically restraining and relaxing the arm during the training process, improving the training efficiency and being convenient to use.

[0054] The end of the placement plate 23 away from the limiting assembly 14 is provided with an air extraction groove 3, the top end of the placement plate 23 is uniformly provided with a plurality of air extraction holes 31 in communication with the air extraction groove 3, the inside of the air extraction hole 31 is inserted with a suction cup 32, the bottom end of the suction cup 32 is in communication and fixedly connected with a connecting barrel 33, the bottom end of the connecting barrel 33 is fixedly connected with a support 34, the support 34 and the inner wall of the air extraction groove 3 are fixedly connected with a buffer spring 35;

[0055] The inside of the air extraction groove 3 is slidably connected with an air extraction block 4, a plurality of supporting springs 40 are fixedly connected between the side surface of the air extraction block 4 and the slot of the air extraction groove 3, the bottom end of the receiving frame 22 is fixedly connected with a toothed plate 24, the inside of the air extraction groove 3 is rotatably provided with a winding wheel 26, the wheel surface of the winding wheel 26 is sleeved with a toothed ring 25 engaged with the toothed plate 24, the wheel surface of the winding wheel 26 and the air extraction block 4 are fixedly connected with a connecting belt 27, the slot of the air extraction groove 3 is rotatably provided with a first receiving roller 29, and the end of the first gap 2 is rotatably provided with a second receiving roller 28;

[0056] When the restraint air bag 16 reduces the restraint on the user's arm, the receiving frame 22 drives the gear plate 24 to move synchronously, the gear plate 24 is in relative engagement with the gear ring 25 to drive the winding wheel 26 to rotate, and the winding wheel 26 winds the connecting belt 27 connected with the wheel surface. When the winding wheel 26 winds the connecting belt 27, the connecting belt 27 pulls the air extraction block 4 in the air extraction groove 3 to move, and the air extraction block 4 moves to the slot position of the air extraction groove 3. In this process, the receiving frame 22 drives the top placement plate 23 to move synchronously. In the initial stage of the movement of the placement plate 23, the height of the suction cup 32 is lower than the top of the air extraction hole 31. As the placement plate 23 drives the air extraction hole 31 to move downward, when the top of the air extraction hole 31 is at the same height as the suction cup 32, the opening of the suction cup 32 is blocked by the surface of the user's arm. In the process of the movement of the placement plate 23, the air extraction hole 31 is continuously blocked. When the air extraction block 4 moves, the sealed space inside the air extraction groove 3 increases, and the air content in the sealed space inside the air extraction groove 3 does not change, so the air extraction groove 3 generates negative pressure. Therefore, when the opening of the suction cup 32 is blocked by the user's arm, the suction cup 32 generates suction on the user's arm. Then, when the movement of the placement plate 23 ends, the suction cup 32 fixes the user's arm. It should be noted that the suction cup 32 is fixed at the top of the connecting cylinder 33, the bottom of the connecting cylinder 33 is fixedly connected with the support 34, and the support 34 is connected with the inner wall of the air extraction groove 3 through the buffer spring 35. When the suction cup 32 is driven to move, the buffer spring 35 is compressed, so that the suction cup 32 does not interfere with the fixation of the user's arm.

[0057] When the movement of the placement plate 23 stops, the suction cup 32 fixes the user's arm, and the user's arm is difficult to fall when it is placed downward, which enhances the connection stability between the user's arm and the device after the restraint and extrusion force of the user's arm is reduced, so that the device is stable on the user's arm when the user normally trains the arm in multiple angles, and the training effect is ensured. After the blood of the user's arm flows smoothly, the placement plate 23 needs to be reset. In the process of resetting the placement plate 23, the receiving frame 22 drives the bottom gear plate 24 to move synchronously, the gear plate 24 is in engagement with the gear ring 25, the gear ring 25 drives the winding wheel 26 to rotate to release the wound connecting belt 27, and the air extraction block 4 at the other end of the connecting belt 27 is reset under the action of the supporting spring 40 when the connecting belt 27 is released, so that the sealed space inside the air extraction groove 3 decreases, the negative pressure inside decreases, the suction force of the suction cup 32 on the user's arm gradually decreases, and finally the suction cup 32 is separated from the user's arm when the placement plate 23 is completely reset, so as to avoid the discomfort of the user caused by the continuous suction of the suction cup 32 on the user's arm. In addition, when the winding wheel 26 winds and releases the connecting belt 27, the connecting belt 27 is always supported by the first supporting roller 29 and the second supporting roller 28, so as to avoid the sliding friction between the connecting belt 27 and the slot of the air extraction groove 3, ensure that the winding wheel 26 winds and releases the connecting belt 27 smoothly, and protect the connecting belt 27.
