Problems solved by technology

The shut-off valve device of the quick joint can ensure the sealing effect of the entire quick joint. During the locking process, when the moving joint pushes the valve core to move inward, the top-mounted spring acts between an annular step on the inner wall of the sliding sleeve and the main body. Next, the tapered surface at the annular concave shoul...

Embodiment Construction

[0018] The embodiment of quick connector of the present invention: as figure 1 , figure 2 As shown, the quick joint is composed of a fixed joint and a moving joint. The fixed joint includes a body 1 and a sleeve 5 threaded on one end of the body 1. The end surface of the body 1 away from the sleeve 5 is provided with a hole communicating with the inner hole of the sleeve. The inner hole of the body, the inner hole of the body is a stepped hole connecting the large hole section and the inner hole of the sleeve. The inner hole of the sleeve and the inner hole of the body form a channel through the fixed joint. The channel is composed of an insertion channel and an air outlet channel. The insertion channel is close to A cut-off valve device is installed at the air outlet position of the air outlet channel; a through hole is opened on one end face of the moving joint 6, which is the air intake channel of the moving joint, and one end of the moving joint 6 is inserted into the air...

Abstract

The invention discloses a quick connector. The quick connector comprises a fixed joint and a movable joint which is matched with the fixed joint in an insertion connection manner; a shutoff valve device is arranged in an insertion connection passage; the sidewall of the movable joint is provided with a step; the sidewall of the fixed joint is provided with a mounting hole which extends along the radial direction, and the tail end of the mounting hole sinks into the internal wall of the insertion connection passage; a button which slides along the extending direction of the mounting hole in a limiting manner is assembled in the mounting hole; a first elastic member which applies an acting force opposite to the bottom face of the mounting hole to the button is arranged between the button and the fixed joint; and the button is provided with a button passage which is used for passing through the insertion end of the movable joint, and a stopping block which is matched with the step of the movable joint in a stopping manner is arranged on the internal wall of the button passage. Due to the structure, the quick connector has the advantages that the quick connector can be automatically locked by directly inserting the movable joint into the fixed joint during locking and can be automatically unlocked by only pressing down the button during unlocking, the phenomenon of skidding can not occur, the operation is convenient, the locking and unlocking of the quick connector can be easily realized, and meanwhile, the sealing effect of the whole quick connector can also be guaranteed.

Description

technical field [0001] The invention relates to a connection device for quick connection and disassembly of gas pipelines, in particular to a quick connector. Background technique [0002] Quick connector is a device widely used in the connection between pipelines. It has the performance of quick buckle and quick disassembly, and has an inseparable relationship with some gas-related industries. There are two types of quick connectors currently on the market. The first type is characterized by simple structure, convenient operation, automatic buckle and spring release, but the airtight effect is not ideal, especially when the pressure is higher, the sealing effect is worse. , and the action is not accurate; the second type is characterized by complex structure, slow assembly, but good air tightness, accurate action, and automatic buckle and spring release. [0003] Chinese patent CN201330906Y discloses a quick connector, which is composed of a fixed joint and a movable joint...
