Preferably: the abutting surfaces of the sealing structure and the limiting structure are conical surfaces, and the abutting surface taper of the sealing structure is larger than that of the limiting structure.
Preferably: and a sealing ring is arranged at the bottom of the abutting surface of the sealing structure.
Preferably: the inner wall of the male connector plug-in end is a wavy curved surface.
The quick connector can be connected through direct plug-in connection of the male connector and the female connector, when the quick connector is installed, the male connector is inserted into the female connector only by manually pulling the sleeve, the sleeve is loosened (the positioning steel balls are moved back and forth along the radial direction in the process of pulling the sleeve to be inserted into the female connector and then fall into the positioning groove, the sleeve is loosened, the sleeve is extruded to fix the positioning steel balls, and in the plug-in process, the valve cores of the male connector and the female connector are mutually propped against each other and then overcome the elasticity of the compression spring to realize pipeline communication), and the quick connector can be detached through reverse operation and is extremely convenient to operate. Besides, the utility model adds a special sealing structure (sealing gasket) besides the structural seal, so that the sealing performance of the connected pipeline is better. The limiting structure in the male connector and the female connector and the structural design of the inner wall of the plug-in end of the male connector can buffer the impact force of fluid in a pipeline when flowing through the quick connector, so that the release possibly caused by long-term use is prevented.
