合成樹脂管用継手

Japanese Patent JP7115016

B2

To provide a joint for a synthetic resin pipe that facilitates the mounting and removal of the synthetic resin pipe.SOLUTION: The joint for a synthetic resin pipe includes a cylindrical body part, a flange part formed at an end of the body part, an operating member mounted on the flange part, and an annular gripping member disposed between the flange part and the operating member, the gripping member being configured to grip a synthetic resin pipe that has been inserted from the side of the operating member. The operating member is in a cylindrical shape with the bottom and configured to house the gripping member and accept the synthetic resin pipe. The gripping member consists of multiple separate gripping members that are separate from each other in the circumferential direction. Each separate gripping member has multiple engaging teeth along the internal circumference. Projections are formed on one side of the opposite surfaces of the multiple separate gripping members on the inner bottom surface or the inner walls of the operating member to engage with circular grooves formed on the other side, which forms a cam mechanism. The cam mechanism changes the rotational operation of the operating member to the radial movement of the multiple separate gripping members and switches the state between a gripping state in which the multiple engaging teeth grip the synthetic resin pipe and a non-gripping state.SELECTED DRAWING: Figure 2
