Problems solved by technology

The quick connector is composed of male connector and female connector. The male plug and the female socket contain a valve structure. The ordinary quick connector is complicated to operate when docking, and the connection is difficult. It is easy to disengage when accidentally touching the opening structure. In order to solve These problems design a new type of quick connector

Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] It should be noted that when a component is said to be "mounted on" another component, it may be directly on the other component or there may be an intervening component. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. When a component is said to be "fixed" to another component, it may be directly fixed to the other component or there may ...

Abstract

The invention provides a quick coupling. The quick coupling comprises a male coupling and a female coupling clamped with the male coupling. When the male coupling is inserted into a first containing cavity, a clamping assembly can be clamped between a positioning ledge and an opening ring to fix the male coupling, a push rod pushes a valve element to extrude a first elastic part to enable a firstpassageway to communicate with a sealing cavity, meanwhile, the push rod extrudes a second elastic part to enable a second passageway to communicate with the sealing cavity, the male coupling continues to be pushed into the female coupling, the clamping assembly can be clamped with the opening ring, at the moment, when the male coupling is pulled outwards, a clamping protrusion can push the opening ring to abut against the positioning ledge, and the male coupling can go over the opening ring and the positioning ledge. The quick coupling has the beneficial effects that the connection steps aresimple, and the operation is easy; and through the arrangement of second containing cavities, when the quick coupling is used for connection, the pressure of internal fluid can jack positioning pins,the higher the pressure of the fluid is, the better the positioning effect of the positioning pins is, and the connection stability of the male coupling and the female coupling is improved.

Description

technical field [0001] The invention relates to a quick disassembly connecting device, especially a novel quick joint. Background technique [0002] Quick connector is a kind of 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 petroleum, metallurgy, hydropower, engineering machinery, marine equipment and other fields. 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 is composed of male connector and female connector. The male plug and the female socket contain a valve structure. The ordinary quick connector is complicated to operate when docking, and the connection is difficult. It is easy to disengage when...
