Patent ID: 7484696

Claim:
A pipe fixing system comprising: a body ( 10 ) provided with a stepped part ( 11 ) formed on the lower portion of the inside thereof for stopping the movement of the end of a pipe ( 1 ) and with a tapered inner peripheral surface ( 12 ) having a diameter gradually narrowed toward the outer side thereof from the inner side thereof; a plurality of jaws ( 20 ) adapted to be guided to the tapered inner peripheral surface ( 12 ) of the body ( 10 ) in such a manner as to be moved toward an inlet ( 13 ) of the body ( 10 ) and fastened in a central direction with respect to the pipe ( 1 ) to serve as wedges in such a manner that the plurality of jaws ( 20 ) are interposed between the tapered inner peripheral surface ( 12 ) of the body ( 10 ) and the outer peripheral surface of the pipe ( 1 ): and a jaw-coupling cylindrical plate spring member ( 30 ) mounted at the inside of the body ( 10 ) in such a manner as to be supported at the lower end thereof by the inner bottom surface of the body ( 10 ), the jaw-coupling cylindrical plate spring member ( 30 ) provided with a plurality of cut lines ( 32 ) formed vertically from the portion separated by a given distance from the lower end thereof to the middle portion thereof in such a manner as to be equally spaced at relatively narrow intervals in a circumferential direction thereof, with a plurality of elastic piece parts ( 33 ) each formed of a plate-like shape and each disposed between the adjacent cut lines ( 32 ) in such a manner as to be bent outwardly to provide an elastic force toward the upper portion thereof, and with a plurality of coupling holes ( 34 ) formed along the peripheral surface thereof on the upper side of the plurality of elastic piece parts ( 33 ) for inserting the plurality of jaws ( 20 ) thereinto such that the plurality of jaws ( 20 ) are kept at a horizontal level.
