Easily assembled quick coupling

Abstract

The invention discloses an easily assembled quick coupling which comprises a outer screw nut, a pivot and an outer sleeve, wherein the two ends of the pivot are a combining end and a positioning end; the combination end stretches into the outer sleeve, and an elastic element is arranged between the combining end and the outer sleeve; the outer sleeve can slide up and down along the pivot; an outer sleeve spring used for supporting the outer sleeve is arranged between the outer sleeve and the pivot; the positioning end is connected with the outer screw nut; a joint valve element is mounted in the cavity of the pivot in a sliding manner; a sealing element is arranged between the joint valve element and the pivot, and a valve element spring used for supporting the valve element is arranged between the valve element and the outer screw nut; a sloping pin hole is formed in the upper part of the pivot; a joint pin used for fixing a core insert which is matched with the easily assembled quick coupling is installed in the pin hole; one end of the joint pin is propped against the elastic element and the other end of the joint pin stretches out of the pin hole. The easily assembled quick coupling utilizes the pyramidal joint pin instead of steel balls used for fixing the core insert in the prior art and is convenient to assemble and high in production efficiency.

Description

technical field [0001] The invention relates to the technical field of quick connectors, in particular to an easy-to-assemble quick connector. Background technique [0002] Quick connectors generally refer to pneumatic quick connectors, which are used to connect two air pipes. One end is the joint end and the other end is the ferrule. When the ferrule is pulled out, the joint end must be sealed to prevent air source leakage. There is a spool, when the ferrule is inserted into the joint end, the ferrule pushes the valve core away, thereby conducting the air connection between the joint end and the ferrule; the quick joint is mainly reflected in the speed, that is, it can be quickly locked after being inserted. , and can be quickly unlocked when the ferrule needs to be pulled out. In the prior art, steel balls are mostly used to fit into the center, and when the ferrule is inserted, it is used to clamp and fix the ferrule. However, the steel ball has a spherical structure, wh...

Problems solved by technology

In the prior art, steel balls are mostly used to fit into the center, and when the ferrule is inserted, it is used to clamp and fix the ferrule. However, the steel ball has a spherical structure, which is very inconvenient to install, time-consuming and laborious, and the production efficiency is low. Therefore, it is urgently needed Improve
