One end of the hinge is connected with the back clip (2), the other end of the hinge is connected with the hard elastic shoulder strap (3), a joint elastic element (such as a torsion spring 17) is additionally arranged on the hinge, and after the self-restoring device is stressed, the joint elastic element (such as the torsion spring 17) can play a certain restoring role. The joint elastic element includes but is not limited to a torsion spring, and other similar joint elastic elements can be used.
As shown in fig. 6, the lumbar support device (4) includes a waist belt (19), an adjustment belt (20), and two side bosses (21). The waistband (19) is of an annular structure, an adjusting belt (20) capable of adjusting the tightness in a telescopic mode is arranged on the waistband, the tightness of the whole waistband is achieved by adjusting the adjusting belt, and people of different body types can be helped to adapt to the carrying device. The fixing buckle (10) is arranged on the outer side of the waistband and used for fixing the buffer device. Fixed knot (10) can use two simultaneously and be arranged in fixed buffer (1) lower extreme whippletree (6), and this fixed knot is openable, when dressing from replying the frame device, opens fixed knot, then the people dresses, when finishing dressing, with fixed knot fixed buffer lower extreme whippletree. When the buffer device is not provided, the fixing buckle can directly fix the lower part of the hard elastic shoulder belt on the lumbar support device.
Two side bosses (21) for mounting lower limb equipment are arranged at two sides of the waistband.
The back clip is of a bionic human back curve structure, and can uniformly disperse the pressure component of the back load weight to the back to the whole back. The upper end of the back clip is connected with the hard elastic shoulder strap. When people wear the backpack device, the hard elastic shoulder straps are lifted upwards, and the shoulder straps rotate upwards around the hinges, so that the wearing action can be realized. The upper end of the back clip is connected with the hard elastic shoulder strap through a hinge.
