Quick connector

Abstract

The invention relates to a connecting device capable of being disassembled and assembled quickly, in particular to a quick connector. The quick connector comprises a male connector and a female connector, wherein the male connector comprises a plug, a plug connector body is arranged on the inner wall of the rear portion of the plug in a sleeving manner, a plug valve seat is arranged in the middleof the inner wall of the plug, a plug valve element is arranged on the front portion of the inner wall of the plug, and a retaining groove is formed in the outer wall of the plug; and the female connector comprises a shell and an outer sleeve, the outer sleeve is arranged on the outer wall of the front portion of the shell in a sleeving manner and connected with a steel ball, the steel ball is arranged in a through hole of the shell, an outer sleeve spring is arranged between the shell and the outer sleeve, a shell connector body is arranged on the inner wall of the rear portion of the shell,a shell valve seat is clamped at the joint of the shell and the shell connector body, a shell valve pad is arranged behind the shell valve seat, the shell valve seat makes contact with a shell valve element nut, the shell valve element nut is sleeved with a shell valve element rod, and the front portion of the shell valve element rod makes contact with the shell valve element. The quick connectorhas the beneficial effects that the structure is novel, the design is ingenious and simple, the shell valve element rod is fixed through the shell valve element nut in a threaded mode, and the largerthe pressure of a Y-shaped ring of a shell valve sleeve is, the better the sealing effect is.

Description

technical field

[0001] The invention relates to a quick disassembly connecting device, especially a quick connector. Background technique

[0002] Quick connectors include hydraulic quick connectors and various fluid quick connectors. It is a connection device that quickly connects or disconnects pipelines and realizes quick disassembly. Because the quick connector has a two-way check function and the pipeline is disconnected without leakage, it is widely used in the fields of petroleum, metallurgy, hydropower, construction machinery, ships, and electromechanical equipment. The connection structure of the quick connector is the most important part of the quick connector. Its connection method and structure directly determine the convenience, reliability and product quality of the quick connector. The quick connector consists of two parts, a female connector and a male connector. The existing high pressure is insufficient in sealing, and may affect the use effect and safety ...
