摘要： A fluid pipe coupling comprises a plug and a socket, at least one of which includes a cylindrical body member having an end portion adapted to engage the other and a caulking end portion, and an adapter member having a connector end portion adapted to be connected with a pipe member and a caulking end portion. One of the caulking end portions has a cylindrical caulking portion, while the other has a cylindrical caulking receiving portion adapted to engage the caulking portion. The caulking receiving portion has a plurality of annular grooves and annular projections therebetween on the peripheral surface thereof. The caulking portion and the caulking receiving portion engage each other with a seal member interposed therebetween. These two portions are caulked so that the cylindrical body member and the adapter member are coupled integrally with each other.

摘要： A pipe coupling comprises a socket and a plug having front end portions engagable with each other. This socket comprises a plurality of lock balls movable to lock positions where the lock balls partially project into an axial bore of the socket body, and a sleeve for holding the lock balls at the lock position. The socket body has a plurality of engage holes elongated in the axial direction. The sleeve is rotatable on the socket body and has a press portion for pressing the lock balls toward the lock positions, a press release recessed portion circumferentially is adjacent to the press portion for retracting the lock balls from the lock positions, and a large diameter portion. The pipe coupling further comprises sleeve-rotation-restricting convex and recessed portions which restrict the rotation of the sleeve relative to the socket body, to an angle range between a press position where the press portions oppose the lock balls and a release position where the press release recessed portions opposed to the lock balls, a collar movable in the large diameter portion, and a spring for urging the sleeve toward the press position and the collar toward the front end.

摘要： A pipe connector comprises a plug having a groove on the outer periphery of the distal end portion thereof, a socket having an axial hole to receive the distal end portion of the plug and a radial hole, a sealing member attached to the socket and sealing the plug and the socket, a lever pivotally mounted on the socket adjacent the radial hole and having a cam engagable with the groove through the radial hole, the lever being movable to a connected position, a half-connected position and a separated position. The cam is engaged with the groove and the sealing member is pressed, while the lever remains in the connected position, the cam is partly engaged with the groove and the sealing member is free from pressure, while the lever remains in the half-connected position, and the cam is disengaged from the groove, allowing the plug and the socket to move relative to each other, while the lever remains in the separated position. The pipe connector further comprises a locking mechanism for preventing the lever from moving with respect to the socket when the lever is in the connected and half-connected position.
