Description

technical field [0001] The invention relates to the protective packaging technology for bullets and arrows, in particular to a rotary single-side opening and adjustable sealing structure. Background technique [0002] The bulletproof packaging system needs very reliable sealing to ensure its use effect. The traditional bulletproof packaging mostly uses the traditional lock-type sealing structure, but in the traditional lock-type sealing structure, the lock depends on the processing accuracy and installation. The accuracy guarantees the compression of the sealing ring, and there are many human factors, and the lock is prone to fatigue after repeated use, which cannot effectively guarantee the airtightness of the bullet protection packaging system. At the same time, the traditional sealing structure requires a long time to open the fixed lock on four sides or two sides. It affects the efficiency and in the traditional sealing structure, the opening takes up a lot of space, so ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a rotary unilateral opening adjustable sealing structure to solve the sealing effect caused by the inconsistent compression of each position of the sealing ring during multiple uses in the traditional sealing structure of the protective package of bullets and arrows. Reduced, it takes a long time to open, and it takes up a lot of space when it is opened
