Claims

[Claim for Utility Model Registration] A pipe joint for connecting flexible pipes with a corrugated cross section, which includes a thread on the outer periphery of the end, a tapered surface that narrows toward the inner periphery of the end, and the inner part of the tapered surface. a main body having a tube end abutment surface and a cylindrical guide extending from the abutment surface toward the end in the axial direction; a gasket attached to the tube end abutment surface; and a female thread that is screwed into the male thread of the main body. a cap nut having a concave groove on the back side of the female thread, the rear inner wall of the concave groove having an inclined surface facing the tapered surface of the main body; and an inner diameter fitted in the concave groove of the cap nut. has an annular shape that is smaller than the outer diameter of the flexible pipe and whose outer diameter is larger than the root diameter of the female thread of the cap nut, which can be expanded and contracted, and whose cross-sectional diameter is thick enough to engage with the corrugated valley of the flexible pipe. by screwing a cap nut onto the main body and inserting the flexible pipe from the rear end of the cap nut, the retainer expands in diameter and the pipe end comes into contact with the abutment surface of the main body;
After that, by tightening the cap nut, the retainer is pressed by the inclined surface of the cap nut and moves forward, and the corrugated tip of the flexible tube is pushed into the gasket from the engaging part of the flexible tube within the tapered surface of the main body to the abutting surface of the tube end of the main body. A flexible pipe joint characterized by crimping through the joint.
