Problems solved by technology

At present, the existing inflatable bags have small inflation space, long inflation time, poor airtightness and easy air leakage, and the air-sealing film is easy to fold, resulting in air leakage
In addition, the accessories of the existing inflatable bag need to be welded by ultrasonic machine, the production efficiency is low, and the dust cover and the main body are excessively matched, and it is easy to fall off under the action of internal stress

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] attached figure 1 Shown is a schematic diagram of the explosion structure of the present invention, which includes: dust cover 1, locking screw 2, latch 3, spring 4, body 5, cylinder core pressing piece 6, sealing rubber pad 7 and cylinder core 8. The cylinder core 8 includes a cylinder core disk 81 and a cylinder core tube 82, and the cylinder core tube 82 is located in the middle of the cylinder core disk 81 and integrally formed therewith. The core pressing piece 6 includes a pressing piece 61 and a sleeve 62, and the sleeve 62 is located in the middle of the pressing piece 61 and integrally formed therewith. The sealing rubber pad 7 is disc-shaped and has a central hole 72 in the middle. The middle part of the body 5 is provided with a support frame.

[0033] The connection relationship between the above parts is: the column core tube 82 passes through th...

Abstract

The invention discloses an air valve for an inflatable bag. The air valve comprises a locking screw, a lock catch, a spring, a body, a cylinder core pressing sheet, a sealing gasket and a cylinder core, wherein the cylinder core comprises a cylinder core disk and a cylinder core tube; the cylinder core tube is positioned in the middle of the cylinder core disk and is integrally formed with the cylinder core disk; the cylinder core pressing sheet comprises a pressing sheet and a casing pipe; the casing pipe is positioned in the middle of the pressing sheet and is integrally formed with the pressing sheet; the sealing gasket is of a disk shape and a cylinder core hole is formed in the middle of the sealing gasket; the cylinder core tube penetrates through the cylinder core hole and then is inserted into the casing pipe; a supporting frame is arranged in the middle of the body; he casing pipe penetrates through the middle of the supporting frame, then is inserted into the spring, and is fixed by the lock catch; and the locking screw is inserted into the cylinder core tube for locking. According to the air valve disclosed by the invention, the air feeding speed of the air valve is improved, the airtightness of the air valve is enhanced, and a production process is simplified; and meanwhile, the problems that a sealing film is easily turned up and a dustproof cover easily falls off are also thoroughly solved.

Description

technical field [0001] The invention relates to the technical field of buffer air bags, in particular to an air valve for an inflatable bag. Background technique [0002] At present, during the transportation process, the container is an important transportation carrier for trade. However, the biggest cargo damage factor during the transportation process is mainly caused by the collision between the goods in the container. In order to avoid collisions between goods and reduce the shock amplitude of goods during transportation, the transportation personnel used the method of filling inflatable bags between the gaps of goods to slow down the shock amplitude. [0003] The structure of the inflatable bag mainly includes two parts: the bag body and the air valve. At present, the existing air bags have small inflation space, long inflation time, poor airtightness and easy air leakage, and the air-sealing film is easy to fold, resulting in air leakage. In addition, the accessorie...
