Abstract

A fluid fast connector comprises an outer shell, an inner shell, a connecting sleeve and a movable sleeve, wherein the inner shell and the connecting sleeve are fixed in the outer shell, the movable sleeve is arranged between the head part of the inner shell and the tail part of the connecting sleeve in a sliding manner, the middle part of the connecting sleeve is concavely provided with a connecting ring, an air cavity is formed between the connecting ring and the outer side of the head part of the movable sleeve, the head part of the outer shell is provided with an air inlet, the outer wall of the inner shell is provided with an air inlet passage for communicating the air inlet with the air cavity, a valve cavity is arranged in the connecting sleeve, a valve core is arranged in the valve cavity, the tail part of the valve core is concavely provided with a supporting ring, a fluid passage is formed on the supporting ring, the side wall of the tail part of the inner shell is provided with a plurality of ball clamping holes for allowing balls to be clamped, the tail part of the inner shell is provided with a sliding sleeve in a sliding manner, and a pressure ring is arranged at a position, corresponding to the ball clamping holes, on the inner wall of the sliding sleeve. The fluid fast connector has the beneficial effects that the supporting ring is arranged at the tail part of the valve core for preventing the valve core from deflecting, the sealing performance is good, seepage is avoided, and the product performance is improved; during connection, butting is convenient, disconnection is labor-saving, and the use is extremely convenient.

Description

technical field [0001] The invention relates to a quick fluid connector. Background technique [0002] Fluid quick connector is a connection device that can be quickly connected or disconnected to realize quick disassembly and assembly of pipelines. It has the characteristics of fast, convenient, safe and reliable connection to system pipelines. Widely used in equipment and other fields. The head end of the existing fluid quick connector is generally connected with the fluid pipe of the fluid storage device, a connection fixing device is arranged at the tail end, and a valve core capable of realizing on-off is arranged inside. When in use, insert the external connector connected to the system pipe of the fluid system to be filled into the tail end of the fluid quick connector, and then fix the external connector through the connection fixing device, and at the same time, the external connector will push the valve core to move to open the fluid Quick connector, the fluid fl...
