Problems solved by technology

Because it is snapped after rotation, the operation of the entire buckle is inconvenient, and the small area of ​​the buckle makes the connection of the entire buckle part unstable. After long-term use, it will cause side deformation and slipping.
The pipe part and the pipe body fastening part of the existing pipe joint are in an active connection state, so that the airtightness of the pipe parts is very poor when they cooperate with each other, and it is not easy to align when the pipe parts are mated

Abstract

The invention relates to a pipeline connecting structure, and belongs to the technical field of pipeline connecting. The pipeline connecting structure comprises a pipe body connecting part and a pipe body buckling part, wherein the pipe body connecting part is used for connecting two pipelines, and the pipe body buckling part is used for sealing and connecting the pipe body connecting part; the matched surfaces of the pipe body buckling part comprise an inclined pipe end combining surface, a first limiting surface and a second limiting surface, and the first limiting surface and the second limiting surface are turned and connected at the edge of the pipe end combining surface, are parallel with the axis of the pipe body connecting part, and are arranged at the two opposite sides of the pipe end combining surface; a convex part is arranged at the first limiting surface, a concave part is arranged at a second limiting surface, a connecting line of matching tracks of the convex part and the concave part is parallel with the pipe end combining surface, and the matching tracks are vertical to the axis of a pipe body part. By adopting the technical scheme, the pipeline connecting structure has the advantages that the assembly is convenient, the fixing structure is firm, and the sealing property is good.

Description

technical field [0001] The invention belongs to the technical field of pipeline connection, in particular to a pipeline connection structure. Background technique [0002] At present, the pipe joints are engaged and rotated for clamping. This existing structure is only for clamping on the outer surface, and the contact area of ​​the clamping is relatively small. Because it is clamped after rotation, the operation of the entire buckle is inconvenient, and the small area of ​​the buckle makes the connection of the entire buckle part unstable. After long-term use, it will cause side deformation and slipping. The pipe part and the pipe body fastening part of the existing pipe joint are in a state of flexible connection, so that the airtightness of the pipe parts is very poor when they are mated with each other, and it is not easy to align when the pipe parts are mated. Contents of the invention [0003] The object of the present invention is to provide a pipeline connection s...
