摘要： PROBLEM TO BE SOLVED: To provide a pipe joint high in connecting reliability and easy in the confirmation of connection to a pipe. SOLUTION: The joint is for inserting a pipe in a joint body for connection in which a space between the inner peripheral face of the joint body and the outer peripheral face of the pipe is sealed by an O-ring, and includes a push-in ring disposed at the inner peripheral part of the joint body and pressed and inserted by a tip of the pipe, an O-ring disposed at a rear part of the push-in ring, a pressing ring abutting on a rear part of the O-ring and urged in the push-in direction of the O-ring, and a lock member positioned at the outer peripheral side of the pipe. When the push-in ring is pressed and advanced by the insertion of the pipe, the O-ring is accordingly pressed by the pressing ring and advanced. In a state that the pipe is not connected yet, a clearance for water leakage is formed between the inner peripheral face of the joint body and the O-ring. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a pipe joint capable of improving pipe connecting work efficiency and facilitating confirmation of normal connection by optimizing screwing depth of a cap nut in the pipe joint to which the end of a connection pipe is inserted to be fastened with the cap nut for achieving connection.
SOLUTION: The pipe joint includes a joint body having a connection pipe insertion recess part between an inner cylinder part and an outer cylinder part formed concentrically on the outside of the inner cylinder part, and the cap nut. When the end of the connection pipe is inserted between the inner cylinder part and the outer cylinder part via an insertion port arranged in the cap nut for the connection pipe and the cap nut is screwed to the outer cylinder part to be fastened around it, the connection pipe is connected by the pipe joint. The pipe joint also includes a positioning lock means positioning an initial screwing position of the cap nut, and a positioning lock releasing means allowing the cap nut to turn when the end of the connection pipe is inserted to the bottom of the connection pipe insertion recess part.
