PIPE CONNECTING DEVICE CAPABLE OF BEING RAPIDLY FIXED THROUGH MINIMUM PROCESSES BY OMITTING TAPPING AND TAPPING PROCESSES

摘要

PURPOSE: A pipe connecting device is provided to enhance air-tightness and fixing force in coupling a pipe connecting device to a target by forming a double expanding member.;CONSTITUTION: A pipe connecting device comprises a connecting member(10), a coupling member(50), a pressurizing member(30), and expanding members(20,40). The connecting member comprises a first through hole and a tightening unit. The tightening unit is formed on one side of the outer circumferential surface of the connecting member. Female threads are formed on the inner circumferential surface of one end of the first through hole and a pipe is connected to the other end of the first through hole. The coupling member comprises a second through hole and male threads. The second through hole is formed on the coupling member and is connected to the first through hole.;COPYRIGHT KIPO 2012
