Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of backpacks, and in particular to a load-reducing backpack. BACKGROUND

[0002] A backpack is an essential carrying tool for students, office workers and travelers. Existing backpacks are divided into single-shoulder backpacks and double-shoulder backpacks, which mainly press the weight of the articles on the shoulders of the human body. The longer the human body bears the backpack, the more painful the shoulders are.

[0003] In order to solve the problem of excessive force on the shoulders of the human body, a load-reducing backpack has appeared on the market. The load-reducing backpack is provided with an elastic and telescopic belt and a limiting body at the connecting part of the shoulder strap and the backpack body. The shoulder strap is connected to the backpack body through the elastic and telescopic belt. One end of the limiting body is fixed to the shoulder strap, and the other end is connected to the backpack body. The length of the limiting body is greater than the original length of the elastic and telescopic belt. In use, the elastic and telescopic belt is used to increase the elasticity of the shoulder strap, so that the shoulder strap has a contraction property. The limiting body is arranged to limit the length of the shoulder strap, so as to avoid excessive elongation of the elastic and telescopic belt. Although the above-mentioned backpack can reduce the load, in actual application, the load-reducing effect of the above-mentioned backpack is not ideal. CONTENT OF THE INVENTION
