Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piping structure for an electric power distribution line,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a piping structure for preventing water leakage by an electric distribution line of a multi-storey house in an apartment building or the like, and more particularly to a piping structure for preventing leakage of water, To an electric distribution line of a multi-family house which blocks the leakage of electric power from the electric wire.

Generally, a cable should be installed in a home or a building to supply electric power to various electric devices such as a lighting device and a heating device, and a cable pipe is installed to prevent the electric wire from being damaged, and then inserted into the pipe .

Especially in places with high humidity such as restrooms or kitchens, cable piping should be installed to prevent the wires from being exposed to water or moisture.

Such cable piping is buried in the bottom of the toilet or kitchen and exposed to the upper side of the floor. Cable piping exposed above the floor is not made of a completely sealed one product, And a plurality of pipes are connected to each other.

Water or moisture is introduced through such a joint pipe, and the water or moisture thus introduced flows into the inside of the cable pipe buried flat on the floor surface, thereby causing a phenomenon of stagnation there.

Such stagnant water or moisture may react with electric wires to cause a short circuit.

In order to solve the above-mentioned problems, for example, the registered patent No. 10-0846618 has been well known.

The prior art includes a leak-barrier box in which a cable pipe is installed, and a sealing means for sealing the open upper end of the cable pipe.

The gasket fixing cap is provided on the lower surface of the lower cable tube, A fixing band provided on an upper surface of the gasket fixing cap and having a through hole through which the upright fastening bolt passes, and a pressure nut which is helically engaged with the upright fastening bolt .

In the conventional electric piping system for blocking water leakage, a waterproof box is hermetically fixed to an upper cable pipe and a lower cable pipe, and a drain hole is formed therein. Even if water or moisture is introduced through the upper cable pipe, There is an advantage.

However, since there is no separate opening / closing part in the leakage blocking box, if there is an error in the leakage blocking box, it is troublesome to repair the upper / lower cable pipe and the leakage blocking box, and the gasket surrounding the outer circumference of the cable There is a problem that it is difficult to keep the fixing force continuously when an impact is applied to the gasket or the fixed cap.

In addition, since the cable protection pipe is inserted into the through hole of the leak-barrier box and is then finished with welding or silicone to fix the cable protection pipe to the leak-barrier box, the cost and time required for the finishing process are increased.

In order to attain the above object, the present invention is characterized in that a semi-circular shape is formed, a first coupling pipe is formed at an inner center thereof, and both ends of the first coupling pipe are formed with a slope angle The first inclined portion is formed at the end of the first inclined portion, the first inclined portion is formed at the end of the first inclined portion, the first drain hole for draining the water introduced into the inside is formed at the bottom surface, A first housing having a flange protruded outward; A semicircular first sealing packing having an outer peripheral surface inclined to be inserted into the first inclined portion so as to be closely contacted and having a first wire insertion hole into which an electric wire is inserted; A first pressing plate which is formed in a semicircular shape to be inserted into the first coupling tube and has fitting grooves at both side end portions thereof and is elastically supported by a first spring toward both sides; A second coupling pipe is formed at an inner center of the second coupling pipe and a second inclined portion is formed at both ends of the second coupling pipe so as to maintain an inclination angle that gradually decreases toward the outside, The second inclined portion is formed with a second female screw portion. The bottom surface of the second inclined portion is provided with a second drain hole for draining moisture introduced therein. A second flange having a second coupling hole is protruded to the outside A formed second housing; A semicircular second sealing packing having a second wire insertion hole formed at an inner center thereof so as to be inserted into the second inclined portion so as to be in close contact with the wire, A second pressing plate which is formed in a semicircular shape to be inserted into the second coupling pipe, has fitting protrusions at both side end portions thereof, and is elastically supported by a second spring toward both sides; And a cable protection tube formed at an end portion of the male screw portion threadably engaged with the first and second internal thread portions.

As described above, according to the present invention, water and moisture are prevented from permeating into the inside of a cable pipe and discharged to the outside, thereby protecting the cable and improving the joint strength and airtightness of components installed to protect the cable, There is a unique effect that can be done.

In addition, since the packing having the inclination angle at both ends of the housing is elastically provided by the spring, even if the time passes, the bonding force of the packing is maintained by the elastic force of the spring. Therefore, the unique effect .
