Abstract

A water outlet structure has a housing with an outlet and an opening. An inner pipe body is assembled into the housing via an assembly portion and connected to the outlet. An assembly ring flange is extended from the rear end of the inner pipe body, A locating ring inserted rotarily onto the rear end of the inner pipe body has a circumferential wall and a penetrating portion, so that said water pipe could pass through the penetrating portion, allowing its outlet end to be inserted into the inner pipe body. A leakproofing member is set between the water pipe and the locating ring or inner pipe body. A turn-lock locator is set correspondingly to the circumferential wall of the locating ring and the assembly ring flange of the inner pipe body, such that the locating ring and the inner pipe body can be rotarily locked and positioned.

Dependent claims

An improved water outlet structure, wherein said water outlet is used for mating onto the outlet end of an existing water pipe, said water outlet comprising:

a housing, formed into a cylindrical shape, and having an outlet at front end of the housing and an opening at rear end of the housing;
an inner pipe body, assembled into the housing via an assembly portion and connected to the outlet;
the inner pipe body having a front end and a rear end;
of which an assembly ring flange is extended from the rear end of the inner pipe body;
a locating ring, inserted rotarily onto the rear end of the inner pipe body, and having a circumferential wall and a penetrating portion, so that said water pipe could pass through the penetrating portion, allowing its outlet end to be inserted into the inner pipe body;
at least a leakproofing member, set between the water pipe and the locating ring or inner pipe body, so that liquid from the water pipe cannot leak;
a turn-lock locator, set correspondingly to the circumferential wall of the locating ring and the assembly ring flange of the inner pipe body, such that the locating ring and the inner pipe body can be rotarily locked and positioned;
said turn-lock locator comprising:
at least two sliding chutes, set at opposite sides on the assembly ring flange of the inner pipe body;
and
a locking portion, protruded directly onto the circumferential wall of the locating ring, and set correspondingly to the sliding chute on the assembly ring flange;
said locking portion consists of a protruding flange, an abutting flange extended to the end of the protruding flange and a locating flange extended to the end of the abutting flange with the same rotation direction as the locating ring;
after the locating ring is rotated, its abutting flange can be abutted onto one end of the sliding chute, while the inner side of the locating flange is tightly coupled with the front side of the assembly ring flange, so that the locating ring and inner pipe body are rotarily locked;
and
a water pipe locator, set correspondingly to the locating ring and the inner pipe body, so that the insertion state of the water pipe could be stably located.
