To maintain the following description of the embodiments of the present disclosure clear and concise, a detailed description of known functions and known components have been omitted from the present disclosure.

As shown in fig. 1 to fig. 2, the lower limb rehabilitation training device provided by the embodiment of the present invention comprises:

the frame body 1 comprises a vertical stand 11 and a seat frame 12 connected with the bottom end of the stand 11, wherein two opposite ends of the stand 11 are respectively provided with a second pulley 124 and a third pulley 125, the seat frame 12 is provided with a horizontal slide rail 121 perpendicular to the stand 11, and one end of the seat frame 12 far away from the stand 11 is provided with a first pulley 123;

the actuating frame 3 comprises a second supporting arm 37 and an actuating frame body 31, one end of the second supporting arm 37 is hinged to one end of the seat frame 12, the first pulley 123 is arranged on the end, the other free end of the second supporting arm 37 is in inserted fit with the actuating frame body 31, and the actuating frame body 31 can slide along the extending direction of the second supporting arm 37; one side of the actuating frame body 31 is provided with a pedal 32, the other side opposite to the pedal 32 is provided with a slide block 5, and the slide block 5 is in sliding fit with the slide rail 121;

the counterweight 2 is movably hung on the vertical frame 11;

and one end of the traction rope 4 is connected to the actuating frame body 31, and the other end of the traction rope 4 sequentially passes through the first pulley 123, the second pulley 124 and the third pulley 125 and is connected with the counterweight 2.

In practical use, the patient can adopt a lying posture, and rehabilitation training is carried out by placing one limb on the action frame 3 and pedaling the pedal 32 by bending the knee. When the patient bends the knee, the counterweight 2 pulls the action frame 3 to slide along the second supporting arm 37 through the traction rope, and when the patient straightens the lower limb, the patient needs to overcome the gravity of the counterweight 2 to do work. Therefore, according to the guidance of the medical staff, the rehabilitation training with proper load can be realized by adjusting the weight of the counterweight.

Specifically, the frame body 31 may be integrally formed, and the sliding block 5 may be directly disposed on the frame body 31, but since the length and the flexibility of the lower limbs are different for different patients, in some embodiments, as shown in fig. 1, a first supporting arm 35 may be disposed on the frame body 31, and the sliding block 5 is disposed on the first supporting arm 35. Meanwhile, based on the same consideration, the actuating frame body 31 may further be provided with a hinge arm 36, one end of the hinge arm 36 is in a plug-in fit with the second support arm 37, and the other end of the hinge arm 36 is hinged with the actuating frame body 31. In this configuration, when the patient steps on the operating frame body 31, the operating frame body 31 can be rotated by the hinge arm 36 at a predetermined angle in addition to the unidirectional operation. As a further improvement, the actuation frame body 31 further includes a connecting rod 34, one end of the connecting rod 34 is hinged to the actuation frame body 31, and the other end is hinged to the hinge arm 36. The link 34 is used to limit the hinge arm from twisting within a certain range, and a limit member 361 for limiting the link 34 may be further provided on the hinge arm 36, as shown in fig. 1.

In the present invention, the second supporting arm 37 provides a sliding support for the actuating frame body 31, and in order to improve the stability of the sliding process, preferably, as shown in fig. 1, the second supporting arm 37 has two free ends (not labeled in the figure) forming a plug part, and the hinge arm 36 is correspondingly provided with two free ends and respectively forms a plug fit with the free ends of the second supporting arm 37. Meanwhile, since the operation frame body 31 is a main component for supporting the lower limbs of the patient, in order to ensure the comfort of the support, as shown in fig. 1, the operation frame body 31 is provided with a flexible support member 33. The flexible support 33 may illustratively be constructed of fabric.

The counterweight 2 is used as a proper load for the patient, and when the patient steps on the pedals 32, the traction rope 4 can pull the counterweight 2 to move up and down, so in order to prevent the counterweight 2 from swinging back and forth, preferably, a guide rod 111 is vertically arranged on the stand 11, and the counterweight 2 is arranged on the guide rod 111 in a penetrating way and can slide up and down along the guide rod 111 under the traction of the traction rope 4. Thus, when the counterweight 2 moves up and down, no shaking is caused, and in order to avoid collision of the counterweight 2 during downward movement, a buffer spring (not marked in the figure) can be further arranged between the counterweight 2 and the bottom of the stand 11.

In addition, in order to facilitate the adjustment of the counterweight, it is preferable that the counterweight 2 includes a traction cover 21 connected to the traction rope and a plurality of counter weights 23.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the protection scope of the present invention is defined by the claims. Various modifications and equivalents of the invention can be made by those skilled in the art within the spirit and scope of the invention, and such modifications and equivalents should also be considered as falling within the scope of the invention.
