Below in conjunction with accompanying drawing, the one-time use process of the present invention is illustrated:

Firstly, the patient needs to lie flat on the waist rehabilitation training machine of the present invention, and the training program is set according to the actual injury situation of the patient's waist.

Option 1: Waist-lifting exercise training

The waist plate 4 that is hingedly connected to the waist plate mounting frame 20 can adaptively fit the patient's waist. At this time, the fourth drive motor 17 is controlled to rotate forward, which drives the lead screw 18 to rotate forward, and then drives the screw nut 19 to rotate along the thread. Lever 18 moves at a constant speed, and pushes up the waist plate installation frame 20 by dowel 23 during the moving process of screw nut 19, and then realizes the upward movement of waist plate 4, and moves up the waist by waist plate 4 to realize the action of straightening the waist. On the contrary, control the fourth driving motor 17 to reversely rotate, the waist plate 4 can be returned to the original position, and so reciprocating, the waist straightening action training can be realized. According to the needs of the patient, the patient can choose the straight or flexed state of the leg.

Program 2: Twisting waist movement training

First control the second drive motor 11 to rotate forward, drive the second worm wheel 12 to rotate forward through the second worm 13, drive the horizontal axis section of the L-shaped rotary shaft 10 to rotate forward through the second worm gear 12, and then drive the chest plate 3 to rotate The axial center line of the horizontal shaft section performs a swing action to realize the waist twisting action. On the contrary, by controlling the second drive motor 11 to rotate in reverse, the waist-twisting action can be realized in reverse, and the waist-twisting action training can be realized by reciprocating in this way.

Program 3: side bending exercise training

First control the third driving motor 15 to rotate forward, drive the driving bevel gear 16 to rotate forward, make the driving bevel gear 16 roll along the circumferential tooth surface of the driven bevel gear 14, force the third driving motor 15 to go around the driving bevel gear 16 The axial center line of the driving bevel gear 16 is rotated, and then the chest plate 3 is driven to rotate around the axial center line of the driving bevel gear 16, so as to realize the side bending action. On the contrary, control the third drive motor 15 to rotate in reverse, can realize reverse side bending action, and so reciprocating, can realize side bending action training.

Program 4: Abdominal crunch training

Firstly, the first driving motor 7 is controlled to rotate, the first worm wheel 9 is driven to rotate by the first worm 8, and the rotation of the first worm wheel 9 drives the head and shoulder board 2 to lift upwards to realize the abdomen crunching action. On the contrary, the first drive motor 7 is controlled to rotate in reverse to realize the upper body is put flat, and so reciprocating can realize the abdominal crunching action training.

Program 5: Leg raising exercise training

By controlling the extension and retraction of the first electric telescopic rod 25, the thigh board 5 can be lifted and lowered. During this process, the calf board 6 and the thigh board 5 remain relatively still, which can ensure that the patient's legs are always straightened. state, by lifting and lowering the thigh plate 5 alternately, the leg-lifting action training can be realized. Through leg raising training, you can help improve the strength of the waist, and ultimately improve the coordination of the waist and legs.

When carrying out plan 1, plan 2 and plan 3, according to the needs of the patient, the patient can choose to lie completely flat or properly lift the head and shoulders for rehabilitation training, or choose to keep the legs in a fully straightened state or in a bent state. Rehabilitation training for legs.

When the patient chooses the proper lifting state of the head and shoulders, it is only necessary to control the rotation of the first drive motor 7, and the rotation of the first worm wheel 9 is driven by the first worm 8, and the rotation of the first worm wheel 9 drives the head and shoulders board 2 to lift upwards. Until the patient feels that the head and shoulders are in the most comfortable position. On the contrary, as long as the head-shoulder board 2 is in the initial position, the patient's head-shoulder portion can be fully flattened to achieve a lying state.

When the patient selects the state of bent legs, the thigh plate 5 is first controlled to be lifted, and then the calf plate 6 is retracted by controlling the second electric telescopic rod 27 to put down, and then the bent legs state can be realized. On the contrary, when the thigh plate 5 and the calf plate 6 are in the initial position, the patient's legs can be completely laid flat to achieve straightening.

The solutions in the embodiments are not intended to limit the scope of patent protection of the present invention, and all equivalent implementations or changes that do not deviate from the present invention are included in the patent scope of this case.
