Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows composition related to the present invention.
Embodiment
The present embodiment provides a kind of plug applied to straight tube end, as shown in Figure 1, including：
End cover 1, has and extend into the interior sealing portion 11 in pipeline 9 and the outer seal portion outside pipeline 9 12, described
Sealing ring is provided between 9 inside of interior sealing portion 11 and pipeline, sealing is provided between 9 outer wall of the outer seal portion 12 and pipeline
Circle, the interior sealing portion 11 and may also set up sealing ring, outer seal portion between 9 end of the connecting portion of outer seal portion 12 and pipeline
12 outside diameter is slightly smaller than the internal diameter of pipeline, and the internal diameter of outer seal portion is slightly larger than the outside diameter of pipeline 9；
Silica gel sealing piece 3, is circle, is arranged on the one end in interior sealing portion 11, for stretching into pipeline, silica gel sealing piece 3
Diameter be slightly larger than pipe diameter, usual big 1-2mm；
Fixed sleeving 4, is set in outside pipeline 9, has the first screw thread, is preferably capable the two halves structure being mutually clamped, with
Facilitate the installation of fixed sleeving 4, the fixed sleeving 4 is provided with anti-slip rubber with pipeline 9, can be further after setting anti-slip rubber
Improve fastness；
Conduit coupling 2, is set in outside end cover 1, including end 21 and fixed tube portion 22, fixed tube portion 22 have
There is the second screw thread with the first thread fitting on fixed sleeving 4, end cover 1, pipeline are abutted against by end 21 after tightening
2 outer wall of connector preferably has an anti-skid chequer, or 21 shape of end of conduit coupling 2 is polygon, such as rectangle, stubborn to facilitate
