It can be customized to match different market demands by changing the size of the pipe connector interface and pipeline connection as needed.

[0005] The technical solution provided by this utility model is as follows: an anti-detachment connector, comprising a connector body, wherein the through hole cross-section of the connector body is circular, and the inner diameter of the through hole of the connector body is the same or variable diameter. One end of the connector body connected to the valve body is provided with a double-layer cylinder, and an annular groove for placing a first sealing ring and a sealing gasket is formed between the inner and outer cylinders. At one end of the connector body near the double-layer cylinder, a plurality of claws are provided along the circumference of the connector body for corresponding to the grooves of the valve body. The plurality of claws and the outer surface of the connector body between the double-layer cylinder form a groove for placing a second sealing ring. The other end of the connector body is used for connection to a system pipeline.

[0006] Furthermore, a connector is provided at one end of the connector body that connects to the system pipeline. The connector is in the shape of a truncated cone, and a bayonet is formed between the connector and the connector body.

[0007] Furthermore, four claws are evenly arranged along the two vertical directions of the cross-section of the connector body, and one end of the claw protrudes outward to correspond to the groove of the valve body. The valve body is provided with a boss that holds the claw.

[0008] Furthermore, each claw has a convenient contact part on its side, which the user can press against with their fingers to easily rotate the connector body during assembly.

[0009] This utility model features an ingenious structural design, high strength, and anti-detachment function, effectively fixing it to the valve body and forming a seal. The connector and valve body are detachable and installable, making it convenient and flexible to use. Different pipe connector interfaces and pipeline connection sizes can be changed as needed, making it widely applicable and highly practical. Attached Figure Description
