Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1-4, the present invention provides a technical solution: an anti-drop plastic pipe plug comprises a pipeline 1 and a pipe plug main body 4, wherein an inner thread is arranged on the inner wall of an outlet of the pipeline 1, the inner thread arranged on the inner wall of the pipeline 1 is screwed with an outer thread 2 distributed on one side of the pipe plug main body 4, a side edge 5 is fixedly connected at the middle position of the pipe plug main body 4, the side edge 5 is of an annular structure with a rectangular cross section, the inner ring of the side edge 5 is attached to the outer end side wall of the pipe plug main body 4, a convex ring 6 is fixedly connected to one end, close to the end provided with the outer thread 2, of the side edge 5, the convex ring 6 is of an annular structure with a rectangular cross section, the convex ring 6 is clamped with a groove arranged on a rubber gasket 3, the rubber gasket 3 is of an annular structure with a concave cross section, one side end face, deviating from the groove, of the rubber gasket 3 is attached to the outlet end of the pipeline 1, the rubber gasket 3 is designed to be of an annular structure with, this design realizes the fixed to 3 positions of rubber gasket for plug main part 4 can not take place deformation at rotatory in-process rubber gasket 3, and it is poor to have sealed effect, the problem of leaking easily to have solved traditional plug main part 4 after fixed.

Spacing groove 7 has been seted up to pipeline 1's exit end, spacing groove 7 is the annular groove structure of rectangle for the cross-section, rubber gasket 3 is the annular structure that the cross-section was h shape, rubber gasket 3's protrusion end and spacing groove 7 looks joint, rubber gasket 3 deviates from one side and 6 looks joints of bulge loop of pipeline 1, with rubber gasket 3 design for the cross-section is the annular structure that the h appears, and rubber gasket 3's protrusion end and 7 looks joints of spacing groove, wherein rubber gasket 3 removes to one side that is close to pipeline 1 in plug main part 4, and then plug main part 4 forces the inside of laminating spacing groove 7 that rubber gasket 3 is inseparabler, make and inlay at the inside pipeline 1 sealing effect of wall body better.

Plug main part 4 deviates from the one end of pipeline 1 and is regular hexagon's prismatic structure for the cross-section, and the prismatic structure that the cross-section is regular hexagon is connected with the spanner looks joint, and this design is convenient for rotate plug main part 4 through the spanner.

The width of the groove on the rubber gasket 3 is the same as that of the convex ring 6, the design is convenient for the rubber gasket 3 and the convex ring 6 to be fixed together closely, and further the stability of fixation between the rubber gasket 3 and the convex ring 6 is greatly improved.

Example 1: with recess on the rubber gasket 3 and the bulge loop 6 looks joint of 5 positions of edge of distribution in the side, then through rotating plug main part 4, and then the external screw thread 2 that distributes at 4 opposite sides of plug main part closes with the internal thread that distributes in 1 inside pipeline soon mutually, at this in-process, plug main part 4 removes to one side that is close to pipeline 1, and then extrudees rubber gasket 3, and rubber gasket 3 seals pipeline 1 at the extruded in-process, it is poor to have sealed effect after fixing to have solved traditional plug main part 4, the problem of leaking easily.

Example 2: with the bulge of 3 one sides of rubber gasket with set up spacing groove 7 looks joint on pipeline 1, then through handle rotating plug main part 4, and then the external screw thread 2 that distributes at 4 opposite sides of plug main part closes with the internal thread that distributes in 1 inside of pipeline soon mutually, wherein 3 convex parts of rubber gasket are in the same place with the inseparable joint of spacing groove 7, plug main part 4 forces the inside of laminating spacing groove 7 that rubber gasket 3 is inseparabler, make and inlay at the inside pipeline 1 sealed effect of wall body better.
