ABSTRACT:
A water pipe connecting structure composed of a hexagonal locking nut, a coupling pipe, a connecting pipe, a metal fastening sleeve and a conic watertight washer. The locking nut has an inner flange at one end. The coupling pipe is divided by an expansion neck portion into an upper head portion and a lower binding portion formed with several slideproof check rings. The coupling pipe is fitted into the locking nut with the expansion neck abutting against the inner flange of the locking nut and with the binding portion extending through the inner flange to insert into the fastening sleeve fitted with one end of the connecting pipe. The fastening sleeve receiving the binding portion is rolled and pressed so as to bind therewith. An outer flange is formed at a top end of the head portion of the coupling pipe. The outer flange has an inclined outer periphery for engaging with the washer and preventing the same from dropping out. The conic washer has a plane flange and is positioned around the head portion of the coupling pipe. The inclined periphery of the outer flange of the head portion is flush with a conic surface of the washer, and the conic surface of the washer is adapted to watertightly abut against an arch reverse angle of an open end of a water incoming pipe screwed in the locking nut. Alternatively, the plane flange of the washer can watertightly abut against a plane open end of a water incoming pipe screwed in the locking nut.
