Claims

[Scope of Claim for Utility Model Registration] 1. In a pipe joint part in which a pipe socket is inserted into the pipe socket via a backing, a flange and a press ring are fitted into the pipe socket in order from the pipe socket side, and the flange and pipe socket are connected to each other. The pipe opening is connected with a connecting tool, and the wedge pieces arranged at approximately equal intervals in the circumferential direction are connected with an elastic member to form a pieced ring having an inner diameter slightly larger than the outer diameter of the pipe insertion opening.
The pieced ring is disposed on a part of the taper formed on the inner peripheral surface of the press ring, and the flange and the press ring are tightened with a tightening tool,
The two arcuate slopes formed on the wedge piece of the ring in the direction perpendicular to the tube axis are brought into sliding contact with a tapered part of the press ring, the rear end surface of the wedge piece is brought into contact with the flange, and the bottom surface of the wedge piece is brought into contact with the pipe. A pipe detachment prevention device in a pipe joint portion, characterized in that the device is brought into contact with the outer periphery of the insertion port. 2 One of the sliding surfaces formed by the tapered part of the press ring and the inclined surface of the wedge piece is made into a convex arc shape in the direction of the tube axis, and one of the contact surfaces formed between the flange and the rear end surface of the wedge piece is made into a convex arc shape in the direction of the tube axis. A pipe detachment prevention device in a pipe joint according to claim 1, wherein the pipe has a convex arc shape.
