Description

A universal pipe plug

technical field

The invention relates to the technical field of auxiliary parts of electric power communication pipelines, in particular to a universal pipe plug device for different line pipes for preventing foreign objects from entering the inside of the line pipe.

Background technique

In the process of laying pre-buried or transporting power line pipes, in order to prevent dust or other debris from entering the wire sheathing pipes, tapes or discarded newspapers are usually used to seal the pipe openings. Such practices are not easy to operate, are not environmentally friendly, and cannot achieve In order to completely seal the nozzle, the phenomenon that the cement slurry penetrates into the line pipe often occurs, which eventually leads to the problem of blockage of the line pipe. In addition, the existing wire sheathing tubes are classified into four categories according to their mechanical properties: light, medium, heavy and super-heavy. Different types of wire tubes have different wall thicknesses and different inner diameters of the wire tubes. , If each type of line pipe is equipped with a corresponding pipe plug, it is easy to cause inconvenient management and waste of molds.

SUMMARY OF THE INVENTION

The present invention provides a universal pipe plug in order to overcome at least one of the above-mentioned defects in the prior art. The aim is to solve the above technical problems at least to a certain extent.

It is not easy to fall out, so the universal pipe plug proposed by the present invention can be used in the inner holes of a variety of line pipes, thereby reducing the cost of mold opening of the line pipe plugs with different inner diameters.

Preferably, the outer diameter of the cover plate is the same as the outer diameter of the line pipe, and the plug body is just plugged into the pipe to seamlessly connect with the end of the line pipe to block the end of the line pipe and prevent debris from entering the pipe.

Preferably, the handle of the pipe plug is a solid body. As a specific embodiment, the handle is in the shape of a solid body arch, which can be divided into two parts. The upper part and the lower part have the same thickness in the direction perpendicular to the central axis of the cover surface; the diameter side of the semicircular pie-shaped edge of the upper part is connected to the upper end of the lower part of the cuboid, and the bottom end of the handle is fixed on the upper part of the cuboid. The center of the upper cover surface of the cover plate is convenient for the insertion and removal of the pipe plug and the line pipe.

Compared with the prior art, the beneficial effects of the technical solution of the present invention are as follows: the present invention has a simple structure, can be installed and disassembled repeatedly, has good toughness, is not easy to break, effectively prevents foreign objects such as cement slurry and dust from entering the wire sheath, and can adapt to A variety of diameters of different line pipes can reduce the cost of mold opening for line pipes and pipe plugs with different inner diameters.

Detailed ways

The accompanying drawings are for illustrative purposes only, and should not be construed as limitations on this patent;

In order to better illustrate this embodiment, some parts of the drawings are omitted, enlarged or reduced, which do not represent the size of the actual product;

It will be understood by those skilled in the art that some well-known structures and their descriptions may be omitted from the drawings.

The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

Referring to Fig. 1, the present invention proposes a universal pipe plug, including a cover plate 2, a plug body 1 and a handle 3. All components of the pipe plug are integrally injection-molded with PE or PP material. As shown in Figures 1 and 2, the handle 3 is in the shape of a solid arch, and the bottom end is fixed at the center of the upper cover surface of the cover plate 2 to facilitate the insertion and removal of the pipe plug and the line pipe, and the lower cover surface of the cover plate 2 is connected to the plug On the upper end of the body 1, the plug body 1, which is connected to the cover plate 2 and extends axially along the lower cover surface of the cover plate 2, is divided into multiple parts by a plurality of spaced air gaps 12, and the bottom surface of the lower end of the plug body 1 is completely open and unsealed. , the lower cover surface of the cover plate 2 , the air space 12 and the inner side surface of the plug body 1 are surrounded to form a cylindrical hollow structure.

1 and 3, the plug body 1 is divided into 4 parts by the air spacer 12, the 4 parts are evenly spaced apart, and each part is provided with a protrusion 11 on the outer surface. Correspondingly, the protrusion There are 4 parts, and the lengths of the 4 parts extending axially along the lower cover surface of the cover plate 2 are the same. As shown in FIG. 4 , when the tube plug is installed, after the plug body 1 is inserted into the lumen of the wire tube 13, it shrinks toward the central axis of the lumen due to the existence of the air space 12, and the smaller the diameter of the lumen, the greater the shrinkage. That is, it can adapt to the shrinkage of the aperture of different wire pipes 13 .
