Problems solved by technology

[0002] Today, with the rapid development of the plastics industry, "replacing steel with plastics" has been realized in more and more industries. Most of the existing plastic pipe joint connection methods use direct processing of threads on two sections of plastic pipes to achieve meshing connection. Corrosion resistance is poor, and it is easier to oxidize than metal. The current method of connecting two plastic pipes is unstable in structure, easily disturbed by external factors, and has a relatively short service life, which cannot meet the needs of the industry.

Abstract

The invention discloses a plastic tube connector connecting structure which is long in service life. The plastic tube connector connecting structure comprises a left plastic tube section and a right plastic tube section, a left metallic sheath concentric with the left plastic tube section is arranged on the outer side of one end of the left plastic tube section, external threads are arranged on the outer side of the left metallic sheath, a right metallic sheath concentric with the right plastic tube section is arranged on the inner side of one end of the right plastic tube section, internal threads meshed with the external threads are arranged on the inner side of the right metallic sheath, the left plastic tube section and the left metallic sheath are of an integrated structure through injection molding, and the right plastic tube section and the right metallic sheath are of an integrated structure through injection molding. The plastic tube connector connecting structure has the advantages that the metallic sheathes are arranged in plastic tube connectors, the plastic tube connectors and the metallic sheathes form a whole through injection molding, the two plastic tube sections are connected in the mode that the threads are machined on the metallic sheathes, the structure is stable, external interference factors are small, and the service life of the plastic tube connectors is greatly prolonged.

Description

technical field [0001] The invention relates to a plastic pipe, in particular to a connection structure of a plastic pipe joint. Background technique [0002] Today, with the rapid development of the plastics industry, "replacing steel with plastics" has been realized in more and more industries. Most of the existing plastic pipe joint connection methods use direct processing of threads on two sections of plastic pipes to achieve meshing connection. Corrosion resistance is poor, and it is easier to oxidize than metal. The current method of connecting two plastic pipes is unstable in structure, easily disturbed by external factors, and has a relatively short service life, which cannot meet the needs of the industry. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a plastic pipe joint structure with long service life. [0004] In order to solve the above technical problems, the technical solution adopted by the pr...
