Claims

[Claims for Utility Model Registration] (1) A main step for attaching the packing is provided near the end of the body, a groove is provided near the tip for fixing the tapered part of the outer ring, and A joint body with a sub-step part for suspending the convex part of the chuck between the step part and the concave groove, a ring-shaped packing fixed on the main step part of the joint body, and an inner wall of the push-ring in the sub-step part. A synthetic resin with elasticity and restoring force, which has a slightly protruding edge part and a slit structure with a collet mechanism, is plated with metal, and the tip is placed in the chuck fixed on the sub-step part and in the groove of the joint body. is a tapered part formed in a chevron shape, a stepped part for locking the push ring is formed on the inner wall, the outer tip of the outer ring whose proximal end has an L-shaped cross section is fitted, and the outer ring is attached to the tip of the main body. an outer ring on which a proximal end portion having an L-shaped cross section is placed; and a stepped portion on the inner peripheral side of the outer ring, which has a tapered portion at the tip corresponding to the tapered portion of the chuck and is engaged with the stepped portion of the outer ring. A pipe joint characterized by comprising a push ring provided on the outer surface and having an L-shaped cross section and an insertion cap. (2) The pipe joint according to claim 1, wherein the distance between the outer diameter part of the chuck and the tapered part of the outer ring is maintained at about the same level as the protruding edge of the chuck. (3) Scope of the utility model registration claim No. 1, which is characterized in that it is a metal-plated chuck with a slit structure in which the base of a cylinder made of synthetic resin protrudes outward and the tip protrudes downwardly inward to form a tapered part. Pipe fitting described in Section 1. (4) The pipe joint according to claim 1, which is a utility model registration, characterized in that it is a metal-plated chuck with a slit structure in which the inside of a flat plate of synthetic resin hangs down inside and is plated with metal.
