[0032] like Figure 1 and Figure 2As shown, support plates 1 are rotatably connected to both sides of the seat plate 2. The hinge axes of the two support plates 1 and the seat plate 2 are located on the lower bottom surface of the seat plate 2, and the support plates 1 and the seat plate 2 are connected by bolts 5.

[0033] As Figure 1 , Figure 2 and Figure 4 shown, a support assembly is provided at the bottom end of the seat plate 2. The support assembly includes a base 4 provided at the bottom end of the seat plate 2. A countersunk hole 26 is provided at the top end of the seat plate 2, and a bolt 10 is screwed in the countersunk hole 26. The bolt 10 is screwed to the base 4.

[0034] As Figure 1 , Figure 2 and Figure 5 shown, multiple connecting rods 28 are provided at the bottom end of the base 4. A support plate 8 is hinged to each connecting rod 28. An end groove 9 is provided on the support plate 8, and a support arm 7 is rotatably connected in the end groove 9. The support arm 7 is connected to the fixing assembly.

When the moving ring 3 resets, it will drive the sliding rod 13 to be received into the top of the receiving slot 27. At this time, the counterweight 19 can be received into the bottom space of the receiving slot 27, thereby helping the user to carry the device.

[0040] Specific usage method and function of this embodiment:

[0041] In the present invention, the training component provided can cooperate with the adjustment component to adjust the position of the counterweight 19 passed through the vertical rod 23 on the movable frame 18, so that the device can be adjusted according to the real-time training state of the patient during the training process. On the one hand, it reduces the strain caused by improper counterweight setting during the patient's training process, and on the other hand, it can also improve the training effect of the device on the patient. Before using the training component, first support the seat plate 2 through the support component and the fixing component, and then fold up the support plates 1 rotatably clamped on both sides of the seat plate 2 upwards. After the support plates 1 and the seat plate 2 are on the same horizontal plane, rotate the bolt 5 to fix the position of the support plate 1. Then rotate the rotating block 11 rotatably clamped at one end of the seat plate 2, so that the movable frame 18 hinged through the connecting block 6 in the rotating block 11 faces downwards. Then move the blocking frame 21 blocked at the top of the vertical rod 23 in the adjustment component, and then pass a certain number of counterweights 19 through the vertical rod 23. After the passing is completed, reset the blocking frame 21. During the movement of the blocking frame 21, it will drive the clamp 25 connected to its bottom end through the telescopic rod 22 to move, so that the clamp 25 is clamped outside the counterweight 19. After that, inflate the air cushion 24 so that the air cushion 24 and the clamp 25 jointly clamp the counterweight 19. After the setting of the counterweight 19 is completed, place the patient's calf inside the inner sides of the two arc-shaped plates 14, and then move the positioning rod 16 connected to the free ends of the straps 17, so that one side of the positioning rod 16 is connected to the fixing rod 15 connected between the two arc-shaped plates 14. At this time, the straps 17 will cooperate with the arc-shaped plates 14 to fix the patient's leg.

[0042] After the patient's leg is fixed, the patient can start training. During the patient's training process, the sensor group provided between the movable frame 18 and the connecting block 6 will monitor the movement state of the patient's leg. At the same time, the device will give a reminder to the patient according to the monitoring results of the sensor group or drive the telescopic rod 22 to extend and retract to adjust the position of the counterweight 19, thereby changing the patient's training intensity.

[0043] The above are only embodiments of the present invention, and common general technical solutions and / or characteristics in the solutions are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope claimed in this application shall be subject to the content of its claims, and the specific implementation manners and the like recorded in the specification can be used to interpret the content of the claims.
