Abstract
Official abstract text for this publication.
A pipe joint made of synthetic resin includes: a joint body including a male screw portion on an outer circumferential portion; and a union nut including a female screw portion formed on an inner circumferential portion such that the female screw portion is tightened onto the male screw portion of the joint body. An outer circumferential surface of the joint body has a projection portion that is integrated therewith and projects radially outward. An inner circumferential surface of the union nut has a convex or concave engagement portion that is integrated therewith and engages with the projection portion when the union nut is tightened up to an appropriate position.
First claim
Opening claim text (preview).
The invention claimed is: 1. A pipe joint made of synthetic resin, comprising: a joint body made of synthetic resin, wherein the joint body comprises a male screw portion on an outer circumferential portion and is mounted to a leading end portion of a tube made of synthetic resin; and a union nut made of synthetic resin, wherein the union nut comprises a female screw portion formed on an inner circumferential portion and that tightens onto the male screw portion of the joint body, wherein one surface of an outer circumferential surface of the joint body and an inner circumferential surface of the union nut has a projection portion integrated with the one surface such that the projection portion projects in a radial direction, the other surface of the outer circumferential surface of the joint body and the inner circumferential surface of the union nut has a convex or concave engagement portion integrated with the other surface such that the engagement portion engages with the projection portion when the union nut is tightened up to an appropriate position, wherein a contact surface is formed on the outer circumferential portion of the joint body, and wherein, in a state in which the joint body and union nut are fully engaged, the contact surface simultaneously contacts an end surface of the union nut when a surface of the projection portion that faces the contact surface engages with a surface of the engagement portion that faces the surface of the projection portion. 2. The pipe joint made of synthetic resin according to claim 1 , wherein the male screw portion and the female screw portion have multiple thread screws. 3. The pipe joint made of synthetic resin according to claim 1 , wherein the engagement portion is moved over the projection portion to engage with the projection portion.
