Air pressure shock-absorbing device of packsack

Abstract

The invention relates to the technical field of backpacks and travelling bags, in particular to an air pressure suspension device of a backpack. The invention includes two sliding bars which are provided with an upper support plate and a lower support plate. At least one air bag type pneumatic pump is arranged between the upper support plate and the lower support plate. The two ends of the air bag type pneumatic pump are respectively connected with the upper and the lower support plates. The invention can be mounted on the back part of the bag. When people climb mountain or walk with heavy burden, the upper and the lower support plates move reversely because of the gravity action of the backpack. The air in the air bag type pneumatic pump is pressed, which causes back pressure, and consequently, realizes suspension effect. People climbing mountain or walking do not feel the pressure of the different gravity of the backpack. Moreover, the invention can be mounted on the backpacks of different designs and can be changed by the user conveniently. Individual requirements of the users can be satisfied.

Description

Technical field: [0001] The invention relates to the technical field of knapsacks and travel bags, in particular to an air pressure shock absorber for a knapsack. Background technique: [0002] Due to the widespread use of backpacks and schoolbags, most people only care about the appearance of the products and often ignore the importance of the actual function and protection of the backpack structure. I believe that ordinary students or tourists have the same experience. When arranging daily activities such as school work or luggage before travel, they often only consider the needs of the items they need to carry, so they keep putting their schoolbags away. And the backpack is filled, but it ignores its own physical fitness and whether the body can cope with these overloaded equipment.

I believe that ordinary students or tourists have the same experience. When arranging daily activities such as school work or luggage before travel, they often only consider the needs of the items they need to carry, so they keep putting their schoolbags away. And the backpack is filled, but it ignores its own physical fitness and whether the body can cope with these overloaded equipment. When the body is under heavy pressure for a long time, it may cause strain on various parts of the body, including hands and wrists, shoulders, neck and back. , more likely to cause permanent damage if not improved

In terms of the structure and function of general traditional school bags and backpacks, there is no related design to provide people with a safer, more comfortable and more efficient product

[0003] In order to reduce the damage caused by the weight of the backpack, someone invented a buffer device on the back, such as installing an air cushion on the back of the backpack, but the buffer device is fixed on the backpack. When the backpack is broken, the buffer device is also scrapped. cause waste of resources
