Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of inflatable bags, and particularly relates to an inflatable bag air valve. BACKGROUND

[0002] At present, the biggest factor of goods damage in the transportation process is the collision between the goods in the front or rear direction, which causes the packaging to be damaged and further causes the goods to be damaged. In order to solve this problem, wood supports or foamed plastics and the like are usually used to fill the gaps between the goods. However, these materials cannot satisfy people in terms of cost and protection effect, and are subject to many limitations. With the increasing environmental protection requirements, wood / foamed plastic and other filling materials are being abandoned. Therefore, people use inflatable bags instead. The inflatable bags can effectively prevent the movement of goods in truck, container or railway transportation, fully fill the gaps between the goods, support the mass generated by the shaking of the goods, absorb the vibration, and protect the goods from damage in transportation, which is better than any other supporting and filling protection effect and more environmentally friendly than the traditional filling method using foamed plastics and the like.

[0003] With the continuous use of inflatable bags, the material of the inflatable bags has been well solved. In order to solve the inflation and sealing effect of the inflatable bags, a one-way check valve is installed. The one-way check valve not only facilitates inflation and deflation, but also is tightly sealed after the valve cover is closed. However, the one-way check valve installed on the inflatable bag can only be inflated and cannot be deflated, which leads to low reusability of the inflatable bag. SUMMARY

[0004] The utility model aims at providing an inflatable bag air valve to solve the problems in the above background.
