Description

Elasticity subtracts burden knapsack based on sheet rubber

Technical Field

The utility model relates to the technical field of backpacks and traveling bags, in particular to an elastic load-reducing backpack based on rubber sheets.

Background

The height of the shoulders of the human body relative to the ground or sea level is in a dynamic change process in the moving process of the human body, the first reason is that when the human body walks, two legs are in the striding and folding alternating process, the height of the shoulders relative to the ground is periodically changed due to the change of angles of lower limbs, the first reason is that when the human body walks on the bottom surface with the changed height, the height of the shoulders can also be changed along with the height of the bottom surface, and the shoulders move up and down in a vertical mode in the walking process by combining the walking characteristic of the human body.

The backpack is a daily product, and when people carry the backpack, the shoulder straps are the main parts for generating stress; when a human body is in a static state, the pressure of the shoulder straps on the shoulders is close to the gravity of the backpack, and the shoulders of the human body are easy to strain; in the process of walking of a human body, due to the fact that the shoulders move in a vertical mode and are generally not provided with elasticity, the shoulder straps generate very high instantaneous pressure on the shoulders, and after the backpack with heavy objects is carried on the backpack for a long time, the problem of shoulder strain is further aggravated;

some backpacks exist in the prior art to relieve the shoulder pressure, for example, a cushion pad is made on the shoulder strap, or the shoulder strap is connected with the backpack through an elastic cushion belt, for example, in the dynamic load-reducing backpack with application number 201920511550.8, the pressure-reducing plate is movably connected with the back plate, and the elastic cushion belt is connected between the lower side of the back plate and the pressure-reducing plate, and provides a cushion between the shoulder strap and the accommodating main body, so that the maximum pressure generated by the shoulder strap on the shoulder of the human body is reduced, and the strain of the shoulder is reduced; however, the deformation ability of the elastic buffer belt in the prior art is not enough, which also results in the deterioration of the burden-relieving effect, and therefore, in order to improve the burden-relieving effect, a novel elastic burden-relieving backpack based on rubber sheets is urgently needed to be provided.
