Spine protection schoolbag for rectification by gas flow bulging based on fluid engineering mechanics

Abstract

The invention discloses a spine protection schoolbag for rectification by gas flow bulging based on fluid engineering mechanics. The structure of the schoolbag includes: accommodating bag, shield, gasstraightener, back strap, the protective plate is positioned on the upper end face of the accommodating bag body and is movably connected with the accommodating bag body, the gas straightening deviceis arranged on the left end face of the accommodating bag body and is integrally structured with the accommodating bag body, so as to pressurize the gas in the interior through deformation of the airpressure chamber, the lower bump is moved by the output of the pipe, such that the orifice plate is deformed, thereby lifting the spine to give it support, and the upper arcuate plate is cushioned byair so as to reduce the force on the shoulder, so as to effectively protect the shoulders and prevent the incoming water flow from being damaged by dampness inside the equipment due to the incoming water flow, and can be used for making the gas inside the equipment more sufficient. The invention relates to a method for preventing the incoming water flow from being damaged by the inclined plate.

Description

technical field [0001] The invention relates to the field of spine-protecting schoolbags, in particular to a spine-protecting schoolbag corrected by gas flow swelling based on fluid engineering mechanics. Background technique [0002] Spine-protecting schoolbags are usually filled with sponge body to form a certain regular shape to disperse the pressure points from the shoulders to the back, so as to achieve the human body's instinctive bending over due to excessive gravity, and long-term hunchback and other symptoms. Such an approach can easily lead to: [0003] When carrying out back loading work, due to the relative concentration of the force points, the internal sponge body is squeezed and deformed under long-term use, thereby reducing the strain capacity, and re-enabling the gravity to be carried on the shoulders. At the same time, under long-term use The internal sponge body is prone to decay and stinks when it is damp, and the device cannot achieve the previous funct...

[0003] When carrying out back loading work, due to the relative concentration of the force points, the internal sponge body is squeezed and deformed under long-term use, thereby reducing the strain capacity, and re-enabling the gravity to be carried on the shoulders. At the same time, under long-term use The internal sponge body is prone to decay and stinks when it is damp, and the device cannot achieve the previous function of protecting the spine, so there is an urgent need for a schoolbag with a new method of protecting the spine
