An inside internal thread section is formed inside of the inner side of the body. An outside internal threaded section is formed inside of the outer side of the body. A diaphragm (30) protects the inside of the outer side of the body.

Description

{PIPELINE ADAPTER FOR CABLE PIPELINE}

The present invention relates to a pipeline adapter that is fixed to the manhole wall when the manhole is configured and the pipeline body is coupled after completion of the manhole, and more particularly, to a pipeline adapter having a separate partition wall formed at an outer bulge to protect the inside of the manhole. will be.

When buried underground cables for ordinary power lines, manholes are required for relaying power lines and underground pipes such as corrugated pipes through which power cables pass in a protected state are connected between manholes and manholes. The underground pipe is connected to the pipe adapter which is fixed to the manhole wall through the pipe body. Therefore, several duct adapters are embedded in the manhole wall before the manhole is constructed.

In general, these pipeline adapters, which are fixed to the manhole wall, are usually in the form of cylinders, and have an inner inner spiral where the inner adapter for protecting the inside of the conduit and adapter is secured inside the inner tube. In order to prevent foreign substances such as cement mortar from flowing into the pipeline adapter when the manhole is constructed, the outer inner spiral portion is formed in which the outer plug is spirally coupled. In order to connect the duct body to the duct adapter, the outer plug is separated and the outer end of the duct body can be helically coupled to the outer inner spiral where the outer plug is helically coupled.

Therefore, the conventional pipe adapter is supplied to the site in the state where the inner stopper and the outer stopper are respectively coupled to the inside and the outside of the manhole wall before being embedded in the manhole wall, and the outer stopper is separated do. These outer stoppers are discarded after they are completely useless.

Thus, the outer cap of the duct adapter becomes a substantially unnecessary part after the duct adapter is embedded in the manhole. However, at the time of manufacturing the duct adapter, an outer stopper must be supplied separately from the duct adapter to be supplied to the duct adapter, which increases the production cost of the duct adapter.

If the means for simply closing the outside of the duct adapter is provided only until the duct adapter is fixedly mounted on the manhole, the manufacturing cost of the duct adapter can be reduced.

In the present invention, the invention was made in view of such a conventional situation, and the outer side of the duct adapter is closed in the form of a diaphragm formed integrally with the duct adapter during molding, and when the duct body is connected to the duct adapter, the diaphragm is simply removed. It is an object of the present invention to provide a pipeline adapter that can be separated, so that the manufacture of the pipeline adapter can be performed more simply than in the conventional case, and the manufacturing cost can be reduced.

To this end, in the present invention, the present invention relates to a pipeline adapter which is fixed to the manhole wall when the manhole is constructed and to which the pipeline body is coupled after completion of the manhole, and flanges are formed on the inside and the outside of the manhole wall, respectively. It consists of a cylindrical body that can be secured and embedded, and an inner inner spiral and an outer inner spiral are formed in the inner inner and outer inner portions of the cylindrical body of the duct adapter, so that the inner plug is spirally coupled to the inner inner spiral and the outer inner spiral The part provides a duct adapter that allows the duct body having an outer spiral to be helically coupled. According to the present invention, a diaphragm for protecting the outer inner portion of the cylindrical body at the position of the outer sphere corresponding to the outer flange on the outer side of the cylindrical body is integrally formed therein during the molding of the cylindrical body, and the flange and At the boundary portion of the diaphragm is characterized in that the circular cutting request is reduced in thickness to facilitate separation of the separation.

Referring to the present invention in more detail based on the accompanying drawings as follows.

Figure 7 is a cross-sectional view showing that the corrugated pipe body is coupled to the pipeline adapter of the present invention and the corrugated pipe which is the underground pipe as a joint pipe to the pipe body again.

The pipeline adapter of the present invention is composed of a cylindrical body 10, which is usually a cylindrical body, as in the case of a conventional pipeline adapter, and flanges 12 and 14 are formed on the inner and outer sides, respectively, and are embedded in the manhole wall 16. It is supposed to be.

The inner inner spiral portion 18 and the outer inner spiral portion 20 are formed in the inner inner portion and the outer inner portion of the cylindrical body 10 of the conduit adapter. As will be described later in detail, the inner plug 24 having the outer spiral 22 is spirally coupled to the inner inner spiral portion 18, and the conduit body having the outer spiral 26 to the outer inner spiral portion 20 ( 28) (refer to FIG. 6) is capable of being screwed together.

According to the present invention, a diaphragm 30 for protecting the outer inside of the cylindrical body 10 at the position of the outer bend corresponding to the outer flange 14 on the outer side of the cylindrical body 10 is provided with a cylindrical body 10. It is molded integrally with this during manufacturing. In addition, a circular cutting request 32 having a reduced thickness is formed at a boundary portion with the flange 14 on the outer surface side of the diaphragm 30 so as to easily cut and separate the diaphragm 30.

Such an inductor adapter of the present invention is closed to the outside of the cylindrical body 10 (outside toward the outside of the manhole) when the operation to secure the cylindrical body 10 to the manhole wall 16 closed by the diaphragm 30. The inner side of the cylindrical body 10 is closed because the inner stopper 24 is closed by the outer helix 22 of the cylindrical body 10 spirally coupled to the inner inner spiral 18 of the cylindrical body 10. Foreign objects such as pieces of cement mortar are prevented from entering. When the pipe fitting is fixed to the manhole wall 16 and the pipe fitting body 28 is connected to the pipe fitting for connecting the cable, the inner plug 24 is separated from the cylindrical body 10 and the cylindrical body 10 is fixed. The diaphragm 30 formed integrally with the portion of the outer flange 14 is cut off using a weak cutting request 32 (FIG. 5). And coupled to the outer end spiral 26 of the conduit body 28 to the exposed outer inner spiral portion 20. Then connect the corrugated pipe 34 to the rear end of the conduit body 28 and fixed to the joint pipe (36).

As described above, the duct adapter of the present invention is formed by cutting the diaphragm integrally on the outer side of the duct adapter to the outside of the manhole, and is closed. The production of is to be performed more simply than the conventional case and to reduce the production cost.
