Description

Technical Field

[0001] The utility model relates to the technical field of PE corrugated pipes, in particular to a PE corrugated pipe which is convenient to connect. Background Art

[0002] PE corrugated pipe, that is, a plastic protective sleeve extruded from polyethylene, is also called a corrugated pipe because of its annular corrugations inside and outside. It protects cables from damage. It has the characteristics of good wear resistance and corrosion resistance. Because PE material is more resistant to corrosion, wear and aging, and is green and environmentally friendly, PE corrugated pipes are also often used as rainwater and sewage branch pipes. Existing PE corrugated pipes are generally installed using third-party tools or threaded connections. After connection, the threaded connection method is prone to loosening and falling off, and has poor stability. Using third-party tools for connection will cause many protrusions at the connection point, which is easy to scratch the staff during use, so it is necessary to improve the existing device to meet actual needs.
