[0042] Specifically, the working process or working principle of the lower limb exercise device for the elderly is as follows: in the specific lower limb exercise for the elderly, usually the elderly exercise their lower limbs by walking. Although this exercise method can exercise the lower limbs, the lower limbs need to bear the weight of the whole body, and the effect of exercising the lower limb muscles is not ideal. In addition, since the elderly exercise for a long time, they need to rest after a period of exercise. When resting, they can only find a stool to rest, which is not comfortable enough and inconvenient for the elderly to exercise. Therefore, a lower limb exercise device specifically for the elderly is needed. When the elderly need to exercise, they can first remove the limit ring 4 from the counterweight rod 39 according to their own ability. After the removal is completed, the elderly can control the number of counterweight rings 41. When completed, The limiting ring 4 is installed back on the surface of the counterweight rod 39. After completion, the elderly can sit on the top of the chair 11. After sitting down, the elderly can pass their two legs through the bottom of the two groups of support rollers 15 respectively. After completion, the two feet are placed on the bottom of the limiting rollers 17 respectively. After completion, the elderly can use the limiting belt 16 to limit the feet, which can improve the stability of the legs. After completion, the elderly can move the lower limbs upward. When moving, the limiting rod 18 can be retracted and extended synchronously, which can reduce the intensity of the exercise when the elderly are exercising, so that the elderly can exercise their lower limbs. The chair is suitable for the elderly and convenient for the elderly to exercise. When the elderly need to rest, the elderly can first sit on the top of the chair 11, and then the elderly can start The electric push rod 21 drives the chair back 23 to rotate. When the demand is met, the elderly can turn off the electric push rod 21. After completion, the elderly can start the massager 38 to massage the back of the body. During the massage, the elderly can heat the cushion 25 as needed to improve the comfort of the elderly. When the elderly rest on the chair 11, the elderly can also extend it by controlling the adjustment frame 33 as needed. The adjustment frame 33 can adjust the position of the display screen 32. After the adjustment is completed, the elderly can watch it. Through the above settings, the comfort of the elderly can be improved when the elderly are resting, and it is convenient for the elderly to use. When the elderly need to adjust the lower limb exercise device according to their height The elderly can start the electric telescopic rod 44 to drive the cushion 25 to slide inside the chair 11. When the adjusted position meets the needs of the elderly, the elderly can close the electric telescopic rod 44 to adjust the position of the cushion 25. When the elderly need to adjust the position of the limit roller 17, the elderly can take out the threaded rod 47 from the inside of the threaded hole 46. After taking out, the elderly can insert the adjustment rod 19 into the inside of the slot 45.
