Referring to fig. 1-3, a three-way quick-connect coupling 100 according to a preferred embodiment of the present invention, wherein the three-way quick-connect coupling 100 can be used to mate three target pipes 801, 802 and 803.
Specifically, in the present invention, the three-way quick-plug connector 100 includes a connector body 10 and at least two sealing rings 20, two of which one of the sealing rings 20 is disposed coaxially with the axial direction of the connector body 10, and at least one of the sealing rings 20 is disposed coaxially with the axial direction of the connector body 10.
With this arrangement, the three-way quick-connect coupling 100 can be stably attached to the target pipe 802.
More specifically, in the present invention, the joint body 10 has a first inserting portion 101, a second inserting portion 102 and a third inserting portion 103, wherein the first inserting portion 101 is axially pressed into the object pipe 801. Annular protrusions with saw-toothed sections and acute-angled tips are formed at a plurality of positions on the outer periphery of the first insertion part 101 in the axial direction, so that the first insertion part 101 can be in interference fit with the target pipe 801 to be stably connected.
The second inserting portion 102 is provided with at least two annular seal grooves 11 at intervals, wherein at least one of the annular seal grooves 11 is axially coaxial with the joint body 10, and at least another one of the annular seal grooves 11 is axially non-coaxial with the joint body 10. At least two sealing rings 20 are disposed in the annular sealing groove 11, so that the second socket part 102 can be stably connected to the target pipe 802.
As can be understood by those skilled in the art, since the one sealing ring 20 is disposed coaxially with the axial direction of the joint body 10, and at least one sealing ring 20 is disposed coaxially with the axial direction of the joint body 10, after the second socket part 102 is butted against the target pipe 802, the sealing rings 20 disposed in the two annular seal grooves 11 can apply forces in different directions to the inner wall of the target pipe 802, and thus the target pipe 802 can be prevented from sliding relative to the second socket part 102.
