[0011] Preferably, a protective pad is fixedly connected to the upper surface of the positioning frame corresponding to the position of the sliding frame, and the protective pad is a rubber pad.

[0012] The effect achieved by the above components is that the damage caused by the collision between the sliding frame and the positioning frame is reduced through the protective pad, and the service life is prolonged.

[0017] Preferably, a plurality of partition plates are fixedly connected to the inner wall of the storage box, and the plurality of partition plates are evenly distributed in the storage box.

[0018] The effect achieved by the above components is that the plurality of counterweight plates are limited by the partition plates, which can prevent the counterweight plates from tipping over and is convenient for the patient to organize and store the counterweight plates.

[0019] In summary, the beneficial effects of the present utility model are as follows:

[0020] In the present utility model, when using the rehabilitation device to train a patient with a knee ligament injury, the patient sits on the chair frame and the chair board, and the leg to be trained of the patient is fixed on the leg binding frame through a binding strap. The patient repeats the action of lifting the lower leg for training. The leg binding frame drives the counterweight frame to rotate through a rotating shaft. By increasing or decreasing the counterweight discs, the resistance received by the patient when lifting the leg is changed. However, the following problems will occur in this operation: there is a lack of a structure for restricting the lifting amplitude. Each time the patient lifts the lower leg, the patient cannot intuitively feel the lifting amplitude and cannot select different lifting amplitudes for training according to their own situation at different training stages. By setting an adjustment structure, the position of the sliding frame is adjusted along the adjustment disc, and the distance between the sliding frame and the positioning frame is changed, thereby restricting the rotation angle of the leg binding frame, which is convenient for the patient to control the lifting amplitude of the knee joint during training according to their own needs, and adopting a progressive training method for the lifting amplitude to improve the training effect.

[0021] During the training process, it is inconvenient to take and store the counterweight discs, and the training resistance cannot be directly changed, resulting in low training efficiency. By setting an auxiliary structure, the counterweight discs are stored in a storage box, which is convenient for the patient to access the counterweight discs, and it is convenient for the patient to increase or decrease the counterweight discs during the training process to change the training resistance.
