Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connecting devices, in particular to a rotary quick-insert pipe joint. Background Art

[0002] A rotary quick-release connector is a sealed rotary connector capable of 360° rotation of the conveying medium. Its main function is to input liquid from a stationary pipe into a rotating or reciprocating device and then discharge it from these devices. This type of connector has a compact design and usually adopts a flange connection, which can be effectively integrated into customer equipment.

[0003] Reference announcement number CN219866794U is an L-shaped rotatable quick-twist air pipe connector, which includes an air pipe connector body, a threaded cap, and a threaded body. One end of the air pipe connector body is connected to the threaded body by riveting, and the other end of the air pipe connector body is fixedly connected to a pipe insertion port. The outer diameter of the pipe insertion port is provided with a thread, and the threaded cap is screwed to the outside of the pipe insertion port by a thread. A sealing groove is provided at the connection between the air pipe connector body and the threaded body, and a joint sealing ring is provided in the sealing groove. In this L-shaped rotatable quick-twist air pipe connector, the air pipe connector body and the threaded body are connected by a riveting structure, which makes the connection more stable and reliable.
