Abstract

The invention provides a quick connector for a gas conveying bellows and belongs to the technical field of connectors. The quick connector solves the problem that an existing quick connector easily causes gas leakage in use. The quick connector comprises a barrel-shaped connecting head. In installation, a sealing washer is sleeved at the end of the bellows. A locating ring, a safety buckle and a locking nut are further sequentially sleeved on the bellows on one side of the sealing washer. The locating ring can be axially fixedly connected with the bellows, one end of the locating ring abuts against one end of the sealing washer, the safety buckle is barrel-shaped and is sleeved at the other end of the locating ring, a clamping part is arranged on an outer side wall of the safety buckle, an annular groove is arranged on an inner wall of the connecting head, and the clamping part is embedded in the annular groove when the locking nut is connected with the connecting head. After the quick connector is installed, one end of the bellows is always kept in a sealed state, and the bellows is good in safety and sealing effect. In addition, a casing of the quick connector is insulated with a bellows body, and the quick connector is safe to use.

Description

technical field [0001] The invention belongs to the technical field of joints, and relates to a quick joint, in particular to a bellows quick joint for gas transmission. Background technique [0002] In the process of using gas, it is often necessary to disassemble and connect the gas pipeline. In order to realize the quickness and safety of the connection and disassembly of gas pipelines, some quick couplings for gas have been designed. [0003] For example, a quick connector for gas bellows proposed by the Chinese patent literature [Application No.: 200910306719.7; Authorization Announcement No.: CN101649937B], including a bellows, a locking nut and a joint with a connecting hole, the bellows is sleeved with a seal A washer and a clamping sleeve that can be snapped into the trough of the bellows, one end of the bellows is inserted through the above-mentioned clamping sleeve and the sealing washer in turn and protrudes into the connecting hole of the joint, and the outer e...
