Description

A self-inflatable split backpack

technical field

The invention relates to the technical field of backpacks, in particular to a self-inflatable split backpack. the

Background technique

At present, backpacks have been widely used by people, and among them, students and mountaineering enthusiasts use the most widely. When people use a backpack, all the weight of the backpack and its contents is applied to the user's shoulders and the middle and lower parts of the back. As students and mountaineering enthusiasts increase the load, an overweight backpack will cause pain in the affected areas of the back and spine. Pain, fatigue. In order to reduce the burden brought by the backpack, in the prior art, a cushioning device is provided on the back of the backpack, and the cushioning device can be a foam material or an air bag. Once the device is made, it has a fixed shape, and the airbag has a fixed amount of air pressure, which cannot be adjusted with the weight of the backpack, and the cushioning effect is still not good. When we pack objects, we usually place heavier objects at the bottom of the backpack. In this way, the entire backpack will be light on the top and heavy on the bottom, that is, the center of gravity of the backpack is at the lower part of the backpack as a whole. Feeling that the entire pack is pressing down on the shoulders and back can be uncomfortable. the

Contents of the invention

The object of the present invention is to provide a self-inflatable split backpack aiming at the deficiencies of the prior art. the

To achieve the above object, the present invention is achieved through the following technical solutions:

A self-inflatable split backpack, including a bag body and a hollow shoulder strap, also includes a sealed back pad, the back pad is provided with a high elastic cotton block, and the back pad is provided with a valve for air in and out, so The shoulder strap is connected to the back pad, and the inner space of the shoulder strap communicates with the inner space of the back pad; the back pad and the back of the bag are connected through a connecting buckle. the

The connecting buckle includes a male buckle and a female buckle, the male buckle is provided with a buckle post, the female buckle is provided with a button hole matching the buckle post, and the buckle post of the male buckle is inserted into the buckle of the female buckle in the hole. the

The four corners of the back pad are respectively provided with connecting ears, the male buttons are arranged on the connecting ears, and the female buttons are arranged on the four corners of the back of the bag body. the

The four corners of the back pad are respectively provided with connecting ears, the female buttons are arranged on the connecting ears, and the male buttons are arranged on the four corners of the back of the bag body. the

The connecting buckle includes a connecting plate, a male buckle and a female buckle, the male buckle is provided with a buckle post, the female buckle is provided with a button hole matching the buckle post, and the buckle post of the male buckle is inserted into the female buckle in the buttonhole of the buckle. the

The connecting plate is arranged on the back pad, the male button is arranged on the connecting plate, and the female button is arranged on the back of the bag body. the

The connecting plate is arranged on the back pad, the female button is arranged on the connecting plate, and the male button is arranged on the back of the bag body. the

High-elastic cotton blocks are arranged inside the shoulder straps. the

The valve includes a valve body and a valve cover, and the valve cover is connected with the valve body. the

The shoulder belt includes an elastic section and a non-elastic section, the elastic section and the non-elastic section are respectively connected to the upper part and the lower part of the back pad, and the elastic section and the non-elastic section are connected through a connecting piece. the

Beneficial effects of the present invention: Since the back pad of the present invention is provided with a high-elastic cotton block, the gas in the back pad and shoulder straps can be discharged by squeezing the back pad. When inflation is required, the valve is opened to expand the high-elastic cotton block , the air pressure in the back pad is less than the outside air pressure, and the outside air enters the back pad through the valve, and because the shoulder strap and the back pad are connected, the inside of the shoulder strap will also be filled with gas; therefore, the back pad and the shoulder strap of the present invention It can be inflated automatically, no inflator is needed to inflate, and the air pressure in the back pad and shoulder strap can also be adjusted by itself, which is convenient to use and saves cost. the
