In the rehabilitation training process, the lifting pull rope 5 controlled by the motor 2 is connected with the elastic sheath 4 and the walking car 1 in cooperation with the tension belt 7, when the lifting pull rope 5 adjusts the position and tension of the elastic sheath 4, the tension belt 7 cooperates, thereby the lower limbs of the patient are trained in a targeted manner, the different muscle groups of the lower limbs are focused on, such as the quadriceps femoris on the front side of the thigh, the biceps femoris on the rear side, etc., and the precision of rehabilitation training is improved.

[0020] As shown in Figure 3As shown, one side of the table plate 19 is rotatably connected with the rotating plate 8, and the movable cavity 3 is closed through the rotating plate 8; the front end of the rotating plate 8 is provided with the clamping strip 9, and the walking vehicle 1 is provided with the clamping groove 10 in which the clamping strip 9 is embedded. The device controls the lifting rope 5 of the elastic sheath 4 by means of the motor 2, and the lower limbs of the patient are subjected to targeted training; by adjusting the position and tension of the elastic sheath 4, different muscle groups of the lower limbs can be focused on, such as the quadriceps femoris on the front side of the thigh and the biceps femoris on the back side, so that the rehabilitation training is more accurate, and the recovery speed of muscle strength is improved. The device can simulate the movement state of the lower limb muscles during normal walking through the cooperation of the elastic sheath 4, the lifting rope 5, the motor 2 and other components, so as to improve the effectiveness of the rehabilitation training. The bottom of the walking vehicle 1 is provided with the brake wheel 14, the brake wheel 14 adopts a 2-inch light full-steel wheel, the installation hole diameter is 6.5mm, and the four-wheel bearing capacity is 150kg; when the patient loses balance, the brake wheel 14 can brake the vehicle in time to avoid accidents. The four corners of the walking vehicle 1 are provided with the adjusting rod 15 containing a plurality of adjusting holes, the adjusting rod 15 is provided with the lifting rod 16 penetrating therein; the rod body of the lifting rod 16 is provided with the spring button 17, and the adjusting rod 15 and the lifting rod 16 are connected with the adjusting holes through the spring button 17, so that the walking vehicle 1 can realize the lifting of the height, and be suitable for the height of different patients.

[0021] Specifically, the two ends of the elastic sleeve 4 are connected by the magic fixing belt 18, which facilitates adjustment according to the thickness of the lower limbs of the patient, can better adapt to the physical characteristics of different patients, and improves the comfort of the patient during use. In the utility model, the design of the fitting mode of the elastic sleeve 4 and the lower limbs fully considers the use experience and rehabilitation needs of the patient. The elastic sleeve 4 is made of high-elasticity, skin-friendly and soft silicone material, which has good flexibility and elastic recovery, can closely fit the curve of the lower limbs, and can avoid excessive compression of the skin, thereby ensuring the comfort of the patient during the rehabilitation training process. The two ends of the elastic sleeve 4 are connected by the magic fixing belt 18, which provides convenience for the adjustment of the fitting degree. The magic fixing belt 18 can be flexibly adjusted according to the thickness of the lower limbs of the patient, so that the elastic sleeve 4 can be stably fixed on the lower limbs and will not be too tight to affect blood circulation. In specific operation, the patient or medical staff can easily tear or paste the magic fixing belt 18 according to the actual situation, so as to realize precise adjustment of the fitting degree of the elastic sleeve 4. In addition, the elastic sleeve 4 is further provided with a soft cotton lining inside, which further improves the comfort when contacting the lower limbs. The cotton lining has good sweat absorption and ventilation performance, can effectively absorb the sweat generated by the lower limbs during the training process, keep the skin dry, and reduce the discomfort and skin problems caused by the accumulation of sweat. In terms of wearing method, the patient first rotates the rotating plate 8 to open, and then opens the elastic sleeve 4 through the magic fixing belt 18. At this time, the patient puts the lower limbs (thighs) into the elastic sleeve 4, adjusts the position, and then fixes the elastic sleeve 4 on the lower limbs through the magic fixing belt 18. This wearing method is simple to operate, and can make the elastic sleeve 4 closely fit the lower limbs, so that the elastic sleeve 4 can effectively cooperate with the lifting pull rope 5 and the tensioning belt 7 to train the lower limbs in a targeted manner, thereby improving the effect of rehabilitation training.

[0022] Preferably, a scale mark can be provided on the lifting pull rope 5, which can also be distinguished by color or number, and is specifically used to adjust the support of the device for the patient, for example, to 30cm position today for rehabilitation activity training, and to 29cm tomorrow, so as to appropriately enhance the intensity of the patient's rehabilitation training. The magic fixing belt 18 can also be provided with a scale mark, which can more intuitively judge the tightness of the fixing.

[0023] Preferably, the upper end surface of the table plate 19 is provided with a backrest 11, which can be used by the patient to rest during the training interval. The upper end surface of the table plate 19 is provided with handrails 12 on both sides of the movable cavity 3, which facilitates the patient to hold and balance. The upper end surface of the table plate 19 is provided with a plurality of placing grooves 13, which can place the personal items of the patient, such as a water cup, a towel, etc., to provide convenience for the patient.

[0024] Working process

[0025] When the patient stands against the wall, the rotating plate 8 is rotated to be opened, so that the device can be moved to the patient's side, then the elastic sleeve 4 is pulled down and the patient's lower limbs (thighs) are fixed in the elastic sleeve 4 by the magic fixing belt 18, and part of the body weight of the patient is supported by the elastic sleeve 4 through the lifting pull rope 5, so that the patient can train more labor-saving and safely in the early rehabilitation training, and the tensioning belt 7 connected with the elastic sleeve 4 is matched to appropriately enhance the strength of the lower limb rehabilitation training, and better meet the rehabilitation needs.

[0026] With the progress of the rehabilitation training, the functions of the lower limbs of the patient are gradually recovered, and a part of the lifting pull rope 5 can be appropriately released by the motor 2, so that the elastic sleeve 4 is lowered, that is, the support of the elastic sleeve 4 to the lower limbs of the patient is reduced, the muscles of the lower limbs are further exercised, and the rehabilitation of the patient is more helpful, so as to achieve the best rehabilitation training effect.

[0027] In summary, the device can be used for targeted training of the lower limbs, and the effect and comfort of the rehabilitation training are improved.
