Rotary type rapid opening sealing structure

Abstract

The invention discloses a rotary type rapid opening sealing structure which comprises a barrel body, a connection pipe, a sealing ring and an end cover. The connection pipe is a cylindrical hollow short pipe, the connection pipe and the barrel body are glued through two-component glue, the outer periphery of the end, away from the barrel body, of the connection pipe is provided with two sets of locking bosses, each set of locking bosses comprise two locking bosses, every two locking bosses are symmetrically distributed about the largest hole diameter of the connection pipe, and one set of locking bosses transversely extend to form a limiting block. The sealing ring is made from silicone rubber, the end cover comprises a cover face and a matching face, one end of the matching face is provided with two sets of locking buckle blocks, the four locking buckle blocks and the four locking bosses are in matched connection, the outer periphery of the end cover is provided with a rubber protection ring, the outer periphery of the end cover is provided with a bolt hole, and a start lever is rotationally connected with the interior of the bolt hole. Each set of locking bosses further comprisea spiral guide face and a plane positioning face which are of an integrated structure, and the tangent line included angle between the spiral guide face and the circumferential face of the front end of the connection pipe is 30 degrees.

Description

Technical field [0001] The invention relates to a bullet and arrow protective packaging technology, in particular to a rotary quick-opening sealing structure. Background technique [0002] The protective packaging system of projectiles and arrows requires very reliable sealing to ensure its use effect. Traditional protective packaging of projectiles and arrows mostly use the traditional lock type sealing structure, but in the traditional lock type sealing structure, the lock is dependent on the processing accuracy and installation Accuracy guarantees the compression of the sealing ring. There are many human factors, and the locks are easily fatigued after repeated use, which cannot effectively guarantee the sealing performance of the bullet and rocket protective packaging system. In the traditional lock type sealing structure, the operation takes up a large space and is not suitable Sealing operation requirements for cylindrical projectile protective packaging structure without s...
