Referring to fig. 3, the thickness of the first sealing ring 9 in the direction from the male joint 1 to the female joint 2 gradually increases, and in the process that the ejector block 10 moves from the male joint 1 to the female joint 2, the sectional area of the inner ring of the first sealing ring 9 also gradually decreases, so that if the hydraulic pressure in the liquid pipeline quick coupling increases, the liquid flowing speed is faster, the first sealing ring 9 is pushed by the ejector block 10 to be abutted against the inner wall of the female joint 2 more tightly, and the purpose of further improving the sealing performance of the joint of the male joint 1 and the female joint 2 is achieved.

Referring to fig. 3, the end of the ejector block 10 far away from the female joint 2 is towards the center from the periphery of the end of the ejector block 10, and is sunken from the male joint 1 to the female joint 2, in the moving process of the ejector block 10, the sunken of the ejector block 10 can enable more liquid to flow to the middle of the end of the ejector block 10 far away from the female joint 2, and the amount of the liquid flowing to the female joint 2 from the space between the ejector block 10 and the first second sealing gasket 22 is reduced, so that the ejector block 10 can bear larger force, the moving distance of the ejector block 10 can be farther, at the moment, the butt of the first sealing ring 9 on the inner wall of the female joint 2 can be tighter, and the purpose of enabling the liquid pipeline quick joint to have better sealing performance is achieved.

Referring to fig. 3, a sealing groove is formed in the inner wall of the female connector 2 along the circumferential direction, a second sealing ring 23 is fixedly connected to the inner wall of the female connector 2, the second sealing ring 23 is annular, the second sealing ring 23 is fixedly connected with the female connector 2 through the sealing groove, and one side, far away from the female connector 2, of the second sealing ring 23 abuts against the outer wall of the male connector 1. In the installation process, the second sealing ring 23 is located between the male connector 1 and the female connector 2, and the second sealing ring 23 can reduce the possibility that liquid flows out from the gap between the male connector 1 and the female connector 2, so that the aim of improving the sealing performance of the quick connector of the liquid pipeline is fulfilled.

The implementation principle of the quick joint of the liquid pipeline in the embodiment of the application is as follows: in the process of installing the liquid pipeline quick connector at the adjacent end parts of the two liquid pipelines, firstly, a first end pipe 11 and a second end pipe 21 are respectively installed at the adjacent end parts of the two liquid pipelines, then, the male connector 1 is inserted into the female connector 2, simultaneously, the gear ring 82 is rotated to enable the screw rod 5 to be in threaded connection with the sleeve 6, and after the screw rod 5 is completely connected with the sleeve 6, the male connector 1 and the female connector 2 can be relatively fixed; sleeve 6 and screw rod 5 distribute along 2 hookup location circumference of female joint, and sleeve 6 and screw rod 5 are parallel with liquid pipeline quick-operation joint length direction to can reduce the possibility that produces relative slope between female joint 2 and the male joint 1, liquid pipeline quick-operation joint is sealed the atress along circumference comparatively even this moment, consequently can reduce the possibility that the weeping condition takes place for male joint 1 and the junction of female joint 2, reached the purpose that promotes the leakproofness of liquid pipeline quick-operation joint.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
