Description

Technical Field

[0001] The utility model relates to the technical field of inflatable packaging bags, in particular to an air leakage-proof inflatable packaging bag. Background Art

[0002] Inflatable packaging is mostly used in bags and luggage. When used as a cushioning package, it is often placed in a carton to prevent the product in the box from directly colliding with other items, and to play a protective and cushioning role. The new packaging system using air cushioning can wrap the product closely and effectively protect the packaged product, not just filling and supporting it. Compared with traditional fillers, it will not cause damage to the items during transportation due to the large gaps in the packaging box, and it can avoid damage even if it is squeezed by external forces. The following problems exist in the existing technology:

[0003] In summary, during use, the existing leak-proof inflatable packaging bags are easily squeezed by external forces, causing the surface of the inflatable packaging bags to be damaged and leaking easily. Secondly, the existing inflatable packaging bags are usually disposable and cannot be reused, thereby reducing their usability. Utility Model Content

[0010] By adopting the above technical solution, the cooperation between the sealing floppy disk and the limiting plate in the solution has the effect of opening and closing the inside of the connecting port.

[0011] A further improvement of the technical solution of the utility model is that a sealing airbag is fixedly connected to the back of the sealing mechanism, the outer diameter of the sealing airbag is larger than the inner diameter of the connecting port, the outer part of the sealing airbag overlaps with the inner part of the connecting port, a clamping pad is arranged on the outer part of the sealing airbag, a limiting protrusion is arranged on the inner wall of the connecting port, and the surface of the limiting protrusion overlaps with the surface of the clamping pad.

[0012] By adopting the above technical solution, the cooperation between the limiting protrusion and the clamping pad in the solution has the effect of limiting the sealing airbag and the connecting port when they are connected.

[0013] A further improvement of the technical solution of the utility model is that the structures of the upper sealed bag airbag and the lower sealed bag airbag are the same, the upper sealed bag airbag includes a protective cover and an airbag sleeve, the inner curvature of the airbag sleeve is consistent with the outer curvature of the inflatable packaging bag, and the inside of the airbag sleeve overlaps the outside of the inflatable packaging bag.

[0016] By adopting the above technical solution, the cooperation between the anti-skid pad and the inflatable packaging bag in the solution can improve the friction on the surface of the inflatable packaging bag and avoid sliding.

[0017] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

The upper and lower ends of the inflatable packaging bag are connected and covered by the upper and lower sealing bag airbags, so as to protect the upper and lower ends of the inflatable packaging bag, and the anti-skid pad increases the friction with the surface of the inflatable packaging bag to prevent the upper and lower sealing bag airbags from being easily separated.
