Description

Technical Field

[0001] The utility model relates to the technical field of pipe joints, in particular to a rotatable pipe joint structure. Background Art

[0002] A rotary joint, also known as a swivel joint or a rotary joint, is a closed rotary connector that can rotate 360° to convey a medium. It is usually used to convey a variety of media such as gas, liquid and oil. The rotary pipe joint has a compact design and is composed of two parts, an inner part and an outer part. The inner part is called an inner bearing and the outer part is called an outer bearing. The inner bearing and the outer bearing are connected to each other through a certain bearing structure to achieve the rotation function of the rotary joint. The rotary joint can be roughly divided into hydraulic rotary joints, high-pressure rotary joints, multi-channel rotary joints, high-speed rotary joints and high-temperature rotary joints. In general, the rotary joint is an important pipeline connection component. Through a special structure and design, the rotation and rotation functions of the pipeline system are realized, which provides convenience for production in various industrial fields.

[0003] For example, Chinese patent CN218032000U discloses a rotatable quick-disassembly pipe joint device, comprising a connecting component, a pipe joint, and a sealing ring and a clamping ring arranged at the connection between the connecting component and the pipe joint. The front end of the pipe joint is provided with an introduction end, a sealing ring assembly groove, and an axial limit boss B in sequence, a matching hole is provided at the axis of the connecting component, and an axial limit boss A is provided on the outer wall of the rear end of the connecting component; the introduction end and the sealing ring assembly groove at the front end of the pipe joint are inserted into the matching hole at the rear end of the connecting component, and the axial limit boss B is fitted with the axial limit boss A; the clamping ring is clamped on the outside of the axial limit boss B and the axial limit boss A, the sealing ring is installed in the sealing ring assembly groove, and fits with the inside of the matching hole.
