Technical Field

[0001] This utility model relates to the field of rehabilitation training device technology, specifically to a lower limb rehabilitation training device. Background Technology

[0002] Currently, some patients in hospitals have lost the ability to move their lower limbs. If they do not engage in regular exercise, their leg muscles will atrophy, causing weakness in their legs and making it impossible for them to walk normally, which seriously affects their subsequent life. Therefore, they usually need to use lower limb rehabilitation training devices for rehabilitation training.

[0003] Currently, existing lower limb rehabilitation training devices have relatively simple structures and limited functions. They cannot adjust the intensity of exercise according to the patient's needs, thus narrowing the overall applicability. Furthermore, the distance between the training device and the seat is often fixed, making it inconvenient for patients with different leg lengths to use. These limitations result in poor practicality.

[0004] Based on this, the present invention designs a lower limb rehabilitation training device to solve the above problems. Utility Model Content
