TECHNICAL FIELD

[0001] The utility model relates to a cable protection pipe, especially a cable protection pipe with a cable pipe plug. BACKGROUND

[0002] In the electric power maintenance well, after the cable protection pipe is threaded, there is a gap between the inner wall of the cable protection pipe port and the outer wall of the cable, and water, dust and other sundries are easy to enter to affect the cable operation, the utility model discloses a kind of inflatable sealing bag cable pipe plugs, inflation is used, expansion, block the gap between the inner wall of the cable protection pipe port and the outer wall of the cable, easy to use, can be used for a long time. SUMMARY

[0003] The utility model discloses a kind of cable pipe plugs, after entering the gap between cable protection pipe port and the outer wall of the cable, inflation, make pipe plug expand radially outward, until the outer surface of pipe plug outer ring and the inner wall of pipe are in full contact, the inner surface of pipe plug inner ring and the outer wall of the cable are in full contact, so that the friction between pipe plug and the inner wall of pipe, between pipe plug and cable is generated, prevent falling off, reach waterproof, dustproof effect.

[0004] The utility model discloses the technical scheme that the utility model solves its technical problem is as follows: cable protection pipe with cable pipe plug, including inflatable bag 1, punch hole 2, protection cover 3, water-swelling sealing strip 4, cable protection pipe 5;

[0005] The inflatable bag 1 is cuboid, including narrow face longitudinal face 11, wide face longitudinal face 12, transverse face 13;There are six faces, two narrow face longitudinal faces 11, two wide face longitudinal faces 12 and two transverse faces 13, two narrow face longitudinal faces 11 are parallel, two wide face longitudinal faces 12 are parallel, two transverse faces 13 are parallel, the narrow face longitudinal face 11, the wide face longitudinal face 12, the transverse face 13 are perpendicular respectively;

[0006] The punch hole 2 includes base 21, punch hole 22;

[0007] The punch hole 2 is located in the middle of any one narrow face longitudinal face 11 of the inflatable bag 1 and is perpendicular to narrow face longitudinal face 11, the base 21 is embedded, the punch hole 22 is exposed, the protection cover 3 is screw threaded with the punch hole 2, the water-swelling sealing strip 4 is two, and is located in the middle of two wide face longitudinal faces 12 respectively;

[0008] The air bag 1 has an outward opening and is in an inflated state inside the cable protection tube 5. The two transverse surfaces 13 are connected to each other to form an annular cylinder. One of the water-swellable sealing strips 4 is in contact with the inner wall of the cable protection tube 5, and the other water-swellable sealing strip 4 is in contact with the outer wall of the cable. The air bag 1 is in a deflated and contracted state inside the cable protection tube 5. One of the water-swellable sealing strips 4 is not in contact with the inner wall of the cable protection tube 5, and the other water-swellable sealing strip 4 is not in contact with the outer wall of the cable.

[0009] The advantages of this utility model are as follows: The air bag 1 has an outward opening and expands inside the cable protection tube 5. One of the water-swellable sealing strips 4 contacts the inner wall of the cable protection tube 5, increasing the friction between the water-swellable sealing strip 4 and the cable protection tube 5. The other water-swellable sealing strip 4 contacts the outer wall of the cable, increasing the friction between the water-swellable sealing strip 4 and the cable. After the cable is threaded through, it seals the port of the cable protection tube, providing waterproofing and dustproofing. The air bag 1 deflates and contracts inside the cable protection tube 5. One of the water-swellable sealing strips 4 separates from the inner wall of the cable protection tube 5, and the other water-swellable sealing strip 4 separates from the outer wall of the cable, allowing it to be easily removed from the cable protection tube 5.
