AI Technical Summary
Technical Problem
When existing cable pipe sealing devices seal cables of different sizes, they cannot effectively achieve the sealing effect, and there are gaps and gaps, which affect the sealing performance.
Method used
The combined structure of rubber airbag, first rubber ring and second rubber ring is adopted, and the internal threaded connection between the screw and the nut is adjusted to adjust the spacing between the rubber ring and inflatable the rubber airbag, making it closely fit with the inner wall of the cable and the pipe to achieve a fixed sealing effect.
Benefits of technology
Effectively prevent external substances from entering the pipeline, ensure the safety and sealing performance of the cables, and are suitable for cables of different sizes.

Abstract
The utility model relates to the technical field of pipeline sealing, and discloses a building cable pipeline sealing device which comprises a rubber air bag, a first rubber ring and a second rubber ring, the rubber air bag is located between the first rubber ring and the second rubber ring, and the opposite sides of the first rubber ring and the second rubber ring are fixedly connected with annular connecting plates. According to the cable pipeline sealing device, the screw is in threaded connection with the interior of the nut, when the screw rotates and moves, the first rubber ring is driven to move at the same time, the distance between the two rubber rings can be adjusted, the rubber air bag is inflated, the rubber air bag can be enlarged, and due to the fact that the front side and the rear side of the rubber air bag are limited, the sealing effect is good. When the front side and the rear side of the rubber air bag are in lap joint with the opposite sides of the two rubber rings, the rubber air bag can be enlarged towards the left side and the right side, then the side surface of the cable can be fastened and attached to the inner wall of the pipeline, the fixed sealing effect is achieved, and external substances are prevented from entering the pipeline.
