構造。[Claims for Utility Model Registration] In a coupling structure in which a coupling tube part formed on one pipe or formed in a lug attached to this pipe is coupled to the other pipe using an adhesive, said coupling tube The inner circumferential surface of the pipe is formed into a tapered hole whose diameter expands in one direction, and the outer circumferential surface of the joint portion of the other pipe is formed into a corresponding tapered shape that can be inserted into and in contact with the tapered hole, and the inner peripheral surface of the joint cylinder portion A female thread is formed at the base end portion of the pipe, and after the other pipe is inserted into the joint cylinder from the enlarged diameter side of the joint cylinder, a female thread is formed at the base end of the pipe. A locking body having a male thread portion to be screwed onto the threaded portion is provided, and the locking body is provided at the threaded proximal end portion of the inner circumferential surface of the connecting cylinder itself or on the connecting cylinder. By screwing the two pipes together, the step portion that the joining side end surface of the other pipe comes into contact with is formed to protrude inward from the inner circumferential surface of the joining cylinder, so that the other pipe can be pulled out from the joining cylinder. A pipe joint structure characterized by having a mechanical joint structure configured to physically prevent pipes from coming off.
