Detailed Description

As shown in fig. 1, the present embodiment discloses a PE fresh air corrugated pipe, which includes a corrugated pipe 1, a PE joint 2 fixedly installed at an end of the corrugated pipe 1 and used for being hermetically connected with a mating joint 4, and a threaded sleeve 3 installed at an outer peripheral side of the PE joint 2 in a threaded manner; a plurality of limiting ribs 2a are fixed on the inner wall of the PE connector 2 along the axial direction, wherein an inserting pipe 5 inserted and installed with the PE connector 2 is installed in the matching connector 4, and an inserting reserved groove 5a matched with the limiting ribs 2a in an inserting manner is formed in the inserting pipe 5; the corrugated pipe 1 is made of PE material, the corrugated pipe 1 and the PE joint 2 are integrally manufactured through a die, threads connected with the threaded sleeve 3 in a threaded mode are arranged on the outer peripheral sides of the PE joint 2 and the matching joint 4, and the PE joint 2 and the matching joint 4 are connected in a sealing mode through the threads.

As shown in fig. 2, the limiting ribs 2a are symmetrically installed inside the PE joint 2, and in a specific implementation, a plurality of limiting ribs may be designed to perform limiting and fixing, wherein the limiting ribs 2a may be fixed by plastic welding thermal fixing manner or integrally formed by a mold, and the thickness of the limiting ribs 2a along the radial direction of the PE joint 2 is 0.5 to 1 cm.

As shown in fig. 3 and 4, an inserting pipe 5 is fixedly installed in the mating connector 4, and the inserting pipe 5 protrudes out of the mating connector 4, so as to be conveniently connected with the PE connector 2 in an inserting manner, wherein an inserting preformed groove 5a on the inserting pipe 5 and a limiting rib 2a in the PE connector 2 are used for limiting and fixing, so that the situation that the mating connector 4 and the PE connector 2 are easily dislocated when the threaded sleeve 3 is used for connecting the mating connector 4 and the PE connector 2 is avoided, and the installation efficiency is affected.

As shown in fig. 5, the PE joints 2 are installed at two ends of the corrugated pipe 1, in a specific implementation, the PE joint 2 is installed at one end of the corrugated pipe 1, and the fitting joint 4 is installed at the other end thereof; thereby serving different lengths.

As shown in fig. 6, the length of the insertion groove 5a on the insertion tube 5 is equal to half of the axial length of the insertion tube 5, so that the insertion tube 5 can stably connect to the limiting rib 2a when torsional stress occurs.
