Description

Technical Field

[0001] The present application relates to the technical field of lower limb exercise, and in particular to a lower limb exercise stretcher. Background Art

[0002] When patients are bedridden due to illness or lower limb injuries, since their legs have not been moved for a long time, their bodies will become weaker and not conducive to physical recovery. Therefore, rehabilitation training for the patients' lower limbs is required.

[0003] The patent document with publication number CN219071128U in the prior art provides a lower limb exercise stretcher. The device is equipped with a motor, a rotating shaft, a main pulley, a transmission belt, a secondary pulley, a rotating shaft, a turntable, a plug column, a movable frame, a guide plate, a guide groove, a connecting plate, a pedal and a belt, which can perform simple rehabilitation training on the patient's legs so that the patient's legs can gradually recover strength. The connecting plate and the movable frame are connected in a sliding manner, which can adapt to different patients. When the patient's legs move up and down, in order to keep the distance between the patient's waist and the connecting plate unchanged, the connecting plate moves on the movable frame, causing the patient's legs to be stretched and pulled, thereby increasing the practicality and scope of application of the device.

[0004] Although the above-mentioned prior art solution can gradually restore the strength of the patient's legs through simple rehabilitation training of the patient's legs, it still has the following defects: the device can drive the patient's legs to move at a certain angle, the range of movement is small, and the use effect is relatively simple.

[0005] In view of this, we propose a lower limb exercise stretching device. Utility Model Content
