Pressure reduction backpack

Abstract

The invention discloses a pressure reduction backpack. The backpack comprises a backpack body, a pressure reduction plate, a pressure reduction component, two shoulder straps and a supporting plate; the supporting plate is arranged on the back of the backpack body, and the pressure reduction plate is arranged on the side, close to the back, on the back of the backpack body; the pressure reductioncomponent comprises a spring mechanism and a hollow shell, the shell is arranged on the back of the backpack body, and the spring mechanism is detachably arranged on the shell; the spring mechanism comprises a compression spring and a telescopic rod, and the compression spring is arranged and limited on the telescopic rod in a sleeving mode; the second end of the telescopic rod and the compressionspring are limited into the shell, and the first end of the telescopic rod is located outside the shell and can up and down stretch and contract relative to the first end of the shell; the first endof the telescopic rod is detachably connected with the lower end of the pressure reduction plate, the upper end of the pressure reduction plate is connected with the upper ends of the shoulder straps,and the lower ends of the shoulder straps are connected with the lower end of the back surface of the backpack body. The pressure reduction backpack can meet different loading use requirements by replacing the compression spring in the pressure reduction component.

Description

technical field [0001] The invention relates to the technical field of backpacks, in particular to a decompression backpack. Background technique [0002] Backpack is a kind of daily necessities. When people carry a backpack on their shoulders, the shoulder strap is the main part of the backpack. Over time, it will easily cause fatigue on the shoulders of people, and then affect the health of the user.
