Abstract

A water pipe joint includes a main body, a control sleeve, and an elastic element. The main body is provided with a plurality of expansion holes and receiving slots. The elastic element is disposed in a receiving gap of the main body. The control sleeve is provided with a plurality of retaining blocks and resilient pieces. The control sleeve is joined with the main body such that the retaining blocks of the control sleeve are slidably received in the receiving slots of the main body, and such that the retaining blocks of the control sleeve are acted on by the elastic element and the resilient piece to extend out of the expansion holes of the main body, so as to be detachably engaged with a water discharging connector.

Claims

1. A water pipe joint comprising:

a main body having an outer cylindrical body and an inner cylindrical body, said outer cylindrical body and said inner cylindrical body defining a gap therebetween, said outer cylindrical body having a plurality of slide slots formed in a periphery thereof, said inner cylindrical body having a plurality of expansion holes formed through a wall thereof, said inner cylindrical body having a plurality of receiving slots corresponding respectively in location to said plurality of slide slots of said outer cylindrical body, said main body having a plurality of guide bevels positioned at junctures of said plurality of receiving slots of said inner cylindrical body and respective expansion holes of said plurality of expansion holes of said inner cylindrical body;

a control sleeve having a connection ring and a plurality of projections, each of said plurality of projections having a pair of track slots slidably cooperative with respective slide slots of said plurality of slide slots on said outer cylindrical body, each of said plurality of projections having an expansion slot formed in an inner surface thereof and a resilient piece extending from said expansion slot, said resilient piece having a retaining block formed at a free end thereof; and

an elastic element received in said gap of said main body said that one end of said elastic element exerts a resilient force against said control sleeve and an opposite end of said elastic element exerts a resilient force against said main body, said control sleeve being joined to said main body such that said pair of track slots of each of said plurality of projections are joined with a plurality of projections are joined with a plurality of position confining edges of said outer cylindrical body, the retaining blocks of said control sleeve being displaced in respective receiving slots of said plurality of receiving slots of said inner cylindrical body, the retaining blocks retained entirely interior of the expansion holes and being cooperative with said elastic element and the resilient pieces of said control sleeve so as to jut out of respective expansion holes of said plurality of expansion holes of said main body so as to retain a water discharging connector therein, the retaining blocks of said control sleeve being retractable into respective receiving slots of said inner cylindrical body so as to enable disengagement from said water discharging connector.
