継手。[Scope of Claim for Utility Model Registration] (1) A telescopic joint provided at the connecting end of a valve such as a water stopcock or a pipe joint, in which an annular protruding band with a slightly larger outer diameter is provided at one end of a pipe-shaped connecting pipe. , an annular gasket groove is formed in this annular protrusion band, an annular gasket is attached to this gasket groove, and
This one end is inserted into the cylindrical inner surface of the connecting end in a sealed manner, and a cap nut is screwed onto the external thread formed on the outer circumferential surface of the connecting end. Attach the ring, bring the split ring and cap nut into contact, and screw the cap nut into the connection end to reduce the diameter of the split ring so that the inner peripheral surface of the split ring contacts the outer peripheral surface of the connecting pipe. A telescopic joint characterized by: (2) The inner diameter of the split ring in its free state is equal to or slightly larger than the outer diameter of the annular protrusion band of the connecting pipe, and the inner diameter when the split ring is reduced until it makes contact is approximately equal to the outer diameter of the connecting pipe. The expandable joint according to claim 1.
