Convenient quick connector

Abstract

The invention discloses a convenient quick connector, and aims to provide a convenient quick connector which is convenient to install, low in cost, simple in structure and high in connection strength. According to the technical scheme, the convenient quick connector is characterized in that the convenient quick connector comprises a primary connector and a secondary connector, the primary connector comprises a shell, a through hole, a pipe connector and a pressing switch, and one side of the shell is detachably connected with the secondary connector; the through hole penetrates through the two sides of the shell in the axial direction; the pipe joint is arranged on the side, away from the secondary connector, of the shell; and the pressing switch is installed in the shell and used for limiting the secondary connector, the pressing switch is used for limiting the secondary connector, compared with the mode that a shell pushes a steel ball, force application is easier, even if the palm is wet and slippery, the quick connector can be disconnected conveniently, and therefore connection and disconnection of the quick connector are more convenient and faster, the other end adopts the pipe connector, the pipe connector is directly connected with a hose, the number of parts of the quick connector is effectively reduced, the use convenience and the practical effect are improved, and the convenient quick connector is suitable for the technical field of connectors.

Description

technical field [0001] The invention belongs to the technical field of connection joints, in particular to a convenient quick joint. Background technique [0002] A quick connector is a connector that can be connected or disconnected without tools, so it is widely used in various fields, usually including female connectors and sub-connectors, the female connector is connected to the hose, and the sub-connector is connected to various connectors Threaded connection, through the cooperation between the female connector and the sub-connector, the quick connection or disconnection of the pipeline is realized. [0003] For example, the Chinese patent application number (CN2009201122655) discloses a quick connector, including a connecting pipe and a cylindrical body, a check valve is arranged in the body, and a sliding core is connected to one end of the body, and several through holes are arranged on the sliding core, and the through holes There are steel balls inside, the outer...

Problems solved by technology

[0003] For example, the Chinese patent application number (CN2009201122655) discloses a quick connector, including a connecting pipe and a cylindrical body, a check valve is arranged in the body, and a sliding core is connected to one end of the body, and there are several through holes on the sliding core. There are steel balls inside, the outer sleeve of the sliding core is provided with a jacket that can move axially along the sliding core, a spring is provided between the jacket and the body, the inner wall of the jacket has an annular groove, the outer wall of the connecting pipe has an annular groove, and the annular groove is close to the interface The side has a lifting surface that can lift the steel ball, and when the connecting pipe is inserted into the sliding core, the one-way valve core is pressed against the connecting pipe under the action of the valve core spring, and the spring is pressed against the outer casing so that the steel balls are respectively against the ring. On the raised surface of the groove and the annular groove, the application slides the jacket so that the steel ball is stuck in the annular groove of the connecting pipe, so as to achieve a fixed connection. However, if the structure is too high, it is easy to be washed away, causing leakage, and it is difficult to assemble. Large, high labor cost, and when in use, it is not easy to apply force to the shell to disconnect the quick connector when the palm is wet and slippery
