Earthquake-proof pipe connection coupling for easying joint and fix

摘要

PURPOSE: An earthquake-proof pipe connection coupling for easily combining is provided to easily fix the combined state of the coupling by press-inserting a shape binding piece and a portion among the outside periphery of an enlargement tip on a socket using a wedge. CONSTITUTION: A washer(2) and a packing ring(1) are fitted to the tip-end of a pipe(20). A pipe fastening cap(30) fitted to the rear side of the pipe. A semicircular shape protruded wheel(21) of a joint portion(20a) on the pipe moves to the left and right directions in a gap between the washer and a supporting ring(32). The joint portion is inserted into the inside periphery of each extended front end portion(10a) of a socket(10). One side of a ring-shaped plate(31) of the pipe fastening cap is combined to a front end flange(11) of the extended front end portion. A wedge(40) press-inserts a portion in between a shape binding piece(33) of the ring-shaped plate and the outside periphery of the extended front end portion.
