Claims

[Claims for Utility Model Registration] (1) A step part is provided at the rear of the fluid passage passing through the socket main cylinder, and the fluid passage whose rear part has a somewhat smaller diameter is connected to the fluid passage through the step part. A cylindrical valve body having a valve head facing the fluid passage and a through hole communicating the inner and outer circumferential parts in the peripheral wall on the rear side is fitted so as to be slidable in the axial direction, and the front opening of the valve body is slidably fitted. A seal ring is provided inside the plug to seal the end face of the plug, and a sliding tube having an axially penetrating fluid passage is fitted therein so as to be able to slide in the axial direction. The contact surface is provided with a locking portion that engages with each other after the valve head of the valve body enters the small diameter fluid passage, and a locking portion is provided between the valve body and the sliding cylinder so that the two are relative to each other. A compression coil spring is interposed to press the socket, and an operating cylinder is loosely fitted to the outer peripheral surface of the socket main cylinder, so that the valve element slides between the operating cylinder and the valve body in the axial direction. Pipe fittings connected like this. (2) A pipe joint of the type in which the connection mechanism between the socket and the plug has a sleeve fitted to the outer peripheral surface of the socket main cylinder, and the sleeve is operated when unlocking the plug, and the sleeve is operated when the plug is unlocked. The pipe joint according to claim (1), which is loosely fitted adjacent to the sleeve.
