[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.

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 arm of the user and is inconvenient because the binding and relaxation of the arm are continuously performed during the training process. In order to solve the above problems, the embodiment of the present application is provided with the placing plate 23, the hydraulic cylinder 21 and other structures, and the specific use process is as follows: when the arm rehabilitation training is performed, the user passes the arm between the placing 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, and the wrist of the user is fixed by the supporting 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 placing plate 23, and the elbow is supported by the elbow supporting member 17. The elbow supporting member 17 is composed of the supporting structure and the supporting structure and is used for supporting the elbow of the user. The upper arm of the user is located below the restraint air bag 16, the top end of the restraint air bag 16 is communicated with a pipeline for inflation, and an external air pump is used to inflate the restraint air bag 16 through the pipeline during use. When the restraint air bag 16 expands, it presses downward against the upper arm of the user, fixing the upper arm of the user at the top end of the placement plate 23. Then, during the auxiliary elbow and arm stretching training, the motor inside the fixing member 11 is driven, the motor drives the rotating disc 12 to rotate, the rotating disc 12 drives the elbow frame 13 to rotate relative to the support member 1, the elbow frame 13 drives the wrist elbow to be fixed by the limiting assembly 14, then the elbow frame 13 is controlled to reset and rotate, the elbow frame 13 drives the user's wrist to reset and move, and one elbow and arm stretching is completed. Then, the above process is repeated to continuously perform the elbow and arm stretching training. When the training has been performed for a period of time, the user's arm needs to be unblocked for blood circulation. At this time, the hydraulic cylinder 21 drives the receiving frame 22 to move downward relative to the support member 1, the receiving frame 22 drives the top end of the placement plate 23 to move synchronously, and the position of the placement plate 23 relative to the restraint air bag 16 increases. Therefore, the restraint air bag 16 is subjected to reduced extrusion force, the restraint air bag 16 reduces the extrusion force on the upper arm of the user at the top end of the placement plate 23, and the restraint degree of the upper arm of the user is reduced, that is, the relaxation of the upper arm is realized, and the smoothness of 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 restraint force of the device on the arm. The elbow and arm stretching process can continue. Based on the above, the hydraulic cylinder 21 and the restraint air bag 16 are arranged in the embodiment of the application. During use, the restraint air bag 16 fixes the upper arm of the user at the top end of the placement plate 23. When the training has been performed for a period of time, the arm of the user needs to be unblocked for blood circulation. At this 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 upper arm of the user at the top end of the placement plate 23, and the restraint degree of the upper arm of the user is reduced, that is, the relaxation of the upper arm is realized, and the smoothness of blood circulation is improved. The problem that the user needs to unblock the arm every period of time to restore the blood circulation of the arm, resulting in reduced training efficiency and inconvenient use is solved. The effect that the arm is continuously and automatically restrained and relaxed during the training process is achieved, the training efficiency is improved, and the use is convenient.

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 which is engaged with the toothed plate 24, a connecting belt 27 is fixedly connected between the wheel surface of the winding wheel 26 and the air extraction block 4, a first receiving roller 29 is rotatably arranged at the slot of the air extraction groove 3, and a second receiving roller 28 is rotatably arranged at the end of the first gap 2; When the restraint air bag 16 is lowered to restrain the upper arm of the user, the receiving frame 22 drives the toothed plate 24 to move synchronously, the toothed plate 24 is relatively engaged with the toothed ring 25 to drive the toothed ring 25 to rotate, the winding wheel 26 is driven to rotate by the toothed ring 25, and the connecting belt 27 connected with the wheel surface of the winding wheel 26 is wound and rolled, when the winding wheel 26 rolls the connecting belt 27, the connecting belt 27 pulls the air extraction block 4 in the air extraction groove 3 to move, 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 placement plate 23 at the top 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 end of the air extraction hole 31, as the placement plate 23 drives the air extraction hole 31 to move downward, when the top end 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 upper arm of the user, in the movement process of the placement plate 23, the air extraction hole 31 is continuously blocked, the inside of the air extraction groove 3 is sealed, the air content in the sealed space of the air extraction groove 3 is unchanged, therefore, the air extraction groove 3 generates negative pressure, therefore, when the opening of the suction cup 32 is blocked by the upper arm of the user, the suction cup 32 generates adsorption to the upper arm of the user, and then, when the movement of the placement plate 23 is completed, the suction cup 32 adsorbs and fixes the upper arm of the user, it should be noted that the suction cup 32 is fixed at the top end of the connecting cylinder 33, the bottom end of the connecting cylinder 33 is fixedly connected with a support 34, the support 34 is connected with the inner wall of the air extraction groove 3 through a buffer spring 35, when the suction cup 32 is driven to move, the buffer spring 35 is compressed, therefore, the suction cup 32 does not interfere with the fixation of the upper arm of the user; When the placing plate 23 stops moving, the suction cup 32 adsorbs and fixes the user's arm, so that the user's arm is not easy to fall when being placed downward, the connection between the device and the user's arm is strengthened after the user's arm is bound and pressed, 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 user's arm is unblocked, the placing plate 23 needs to be reset, in the resetting process of the placing plate 23, the receiving frame 22 drives the bottom end of the tooth plate 24 to move synchronously, the tooth plate 24 is in meshing transmission with the tooth ring 25, the tooth ring 25 drives the winding wheel 26 to rotate to release the winding connection belt 27, when the connection belt 27 is released, the air extraction block 4 at the other end of the connection belt 27 is reset under the action of the supporting spring 40, the internal sealed space of the air extraction groove 3 is reduced, the internal negative pressure is reduced, the adsorption force of the suction cup 32 on the user's arm is gradually reduced, and finally the suction cup 32 is separated from the user's arm when the placing plate 23 is completely reset, so that the user is not uncomfortable due to the continuous adsorption of the suction cup 32 on the user's arm; in addition, when the winding wheel 26 winds and releases the connection belt 27, the connection belt 27 is always received by the first receiving roller 29 and the second receiving roller 28, so that sliding friction is avoided between the connection belt 27 and the slot of the air extraction groove 3, the winding and releasing process of the winding wheel 26 is kept smooth, and the connection belt 27 is protected.

[0024] A plurality of flow-through gaps 5 are arranged at the top end of the placing plate 23 between the air extraction holes 31, a jet hole 52 in communication with the air extraction groove 3 is arranged at the top end of the flow-through gap 5, a plugging block 53 is inserted into the jet hole 52, a baffle 54 is fixedly connected to the top end of the plugging block 53, and a plurality of through holes are arranged in the surface of the baffle 54. An air hole 41 is arranged in the side surface of the air extraction block 4, a guide rod 44 is inserted into the air hole 41, and a fixed frame is fixedly connected to the inside of the air hole 41; the guide rod 44 penetrates through the fixed frame, one end of the air hole 41 and the slot of the air extraction groove 3 is slidably connected with a plugging block 45, the plugging block 45 is fixedly connected with the end of the guide rod 44, the end of the guide rod 44 away from the plugging block 45 is located outside the air hole 41, a push plate 43 is sleeved with the part of the guide rod 44 outside the air hole 41, and a pair of limiting springs 42 are fixedly connected between the push plate 43 and the fixed frame; a fixed sheet 46 is fixedly connected to the side of the air extraction block 4 facing the slot of the air extraction groove 3, a connecting spring 47 is fixedly connected to the end of the fixed sheet 46 away from the air extraction block 4, a vibration sheet 48 is fixedly connected to the bottom end of the connecting spring 47, a pair of recesses 30 are arranged in the inner bottom wall of the air extraction groove 3 between the air extraction block 4 and the slot of the air extraction groove 3, a blocking block 301 is inserted into the recess 30, and a reset spring is fixedly connected between the bottom end of the blocking block 301 and the inner wall of the recess 30. When the air extraction block 4 is reset, the air extraction block 4 drives the fixed sheet 46 to move synchronously, the fixed sheet 46 drives the vibration sheet 48 at the bottom end of the end connecting spring 47 to move synchronously, the vibration sheet 48 is blocked by the block 301 during the movement, when the block 301 blocks the vibration sheet 48, the vibration sheet 48 is first deflected, the connecting spring 47 at the top end of the vibration sheet 48 is bent, when the connecting spring 47 is bent to a certain degree, the vibration sheet 48 will pass the block 301, and then hit the end of the guide rod 44, which is the energy storage and release process of the vibration sheet 48. After the guide rod 44 is hit, the guide rod 44 drives the push plate 43 and the blocking block 45 to move synchronously, specifically, the guide rod 44 drives the push plate 43 to move towards the air extraction block 4, and the blocking block 45 is separated from the air hole 41 during the movement, so that the internal sealed space of the air extraction groove 3 is no longer sealed. When the push plate 43 moves towards the air extraction block 4, the push plate 43 pushes the air outside into the internal sealed space of the air extraction groove 3 through the air hole 41, so that the air content in the internal sealed space of the air extraction groove 3 increases instantaneously, and the gas pressure is higher than the atmospheric pressure. Under the action of the gas pressure, the blocking block 53 in the air injection hole 52 is lifted and moves upwards to open the air injection hole 52, and at the same time, the blocking block 53 drives the baffle 54 at the top end to move synchronously. The air in the internal sealed space of the air extraction groove 3 is injected out of the air injection hole 52, and then acts on the surface of the baffle 54, flows into the internal flow gap 5 through the baffle 54, and then is injected out of the flow gap 5 at both ends. The airflow in the internal flow gap 5 acts on the user's arm to dry the user's arm, and at the same time, carries away the heat accumulated between the user's arm and the placement plate 23, improving the comfort of the user's arm.

[0025] The side of the block 301 facing the air extraction block 4 is arc-shaped, the vibration sheet 48 can extrude the arc-shaped surface of the block 301 during the movement, so that the block 301 moves downwards; when the air extraction block 4 moves to the slot position of the air extraction groove 3, the air extraction block 4 drives the fixed sheet 46 to move synchronously, the fixed sheet 46 drives the vibration sheet 48 at the bottom end of the end connecting spring 47 to move synchronously, the vibration sheet 48 is blocked by the block 301 during the movement, when the arc-shaped surface of the block 301 is extruded by the vibration sheet 48, the block 301 is subjected to downward extrusion force, and under the action of the extrusion force, the block 301 extrudes the reset spring downwards. When the top end of the block 301 is lower than the vibration sheet 48, the vibration sheet 48 passes the block 301, and the vibration sheet 48 moves with smaller transverse blocking force, so that the vibration amplitude of the vibration sheet 48 is smaller when the vibration sheet 48 passes the block 301.

It should be noted that when the blocking block 53 is reset, the blocking block 53 is made of magnetic material, and the inner wall of the air injection hole 52 is provided with a magnetic sheet, so that the blocking block 53 can be magnetically attracted when it is reset, avoiding the situation that the bottom end of the blocking block 53 is blocked by the top end of the air injection hole 52 and cannot be reset.
