Fig. 1 is a structural schematic diagram of a weight loss training device for gait rehabilitation.

Detailed ways

The present invention is illustrated below in conjunction with accompanying drawing.

With reference to Fig. 1, gait rehabilitation weight loss trainer of the present invention comprises support frame, spring support system, armrest mechanism and base:

The support frame includes a U-shaped support 1, an axle seat 3 positioned at the two ends of the U-shaped support 1 opening and a bottom edge corner, a guide shaft 4, a post seat 20 and a support rod 21, and the axle seat 3 is fixed on the U-shaped support 1. One end of the guide shaft 4 is inserted into the hole of the shaft seat 3 and fastened with a screw, and the other end is fixedly connected with the post seat 20, and the support rod 21 upper end is inserted in the hole of the post seat 20 and fastened with a screw. Wherein the parts in the U-shaped bracket 1 and the support rod 21 are all industrial standard parts, and profiles are used as the main body of the U-shaped bracket 1 to take advantage of its firmness and light weight.

The spring support system includes a fixing piece 5, a back plate 6, a beam 7, a connecting bracket 8, two weight-reducing beams 10, two support beams 14, a first linear bearing 9, a spring 11, a spring sleeve 12, a second linear The bearing 13 and the tension sleeve sleeve 15, the tension sleeve sleeve 15 and the guide shaft 4 are fixed through the tension sleeve, and the two weight-reducing beams 10 are respectively set on the two sides of the U-shaped bracket 1 through the first linear bearing 9. On the guide shaft 4, the crossbeam 7 is fixed between two weight-reducing beams 10 through the connecting bracket 8, the fixing part 5 is fixed in the middle of the crossbeam 7, the back plate 6 is fixedly connected with the fixing part 5, and the end of each weight-reducing beam 10 partly press one end of the spring 11, and the other end of the spring 11 goes deep into the round hole of the spring sleeve 12, and after the installation holes of the spring sleeve 12 and the second linear bearing 13 are aligned, they are fixed to the support under the weight reducing beam 10 by screws. On the beam 14, the support beam 14 is pressed on the tensioner sleeve 15. The weight loss training belt and the lower extremity exoskeleton are fixed on the backboard. After the person wears the weight loss training belt and the lower limb exoskeleton, they walk on the ground. The spring support system moves up and down along the guide shaft 4 as the center of gravity of the person moves in the vertical direction Sliding, linear bearings ensure low friction and low noise sliding. When the weight reduction ratio needs to be adjusted, the screw of the tensioner sleeve is loosened, and after the spring support system is adjusted to a specified position, the screw is tightened to realize fixing on the guide shaft 4 .

Handrail mechanism comprises adjusting screw 16, telescopic shaft 17, armrest frame 18 and handrail 19, and the side of telescopic shaft 17 and support beam 14 adopts profile connection, is fixed by adjusting screw 16, and position is adjustable, and armrest frame 18 is fixed with telescopic shaft 17.
