Multiple through holes are provided with, the upper surface setting annular groove corresponding with the lateral wall of rubber parts of the second described pressing plate is described
The lower end of lateral wall be caught in inside annular groove；The inwall of annular groove raises up and is located at rubber parts on second pressing plate
Inner space between madial wall, lateral wall, the inwall of the second pressing plate are obliquely installed, the raised upper end of the second pressing plate it is interior
Footpath is more than the internal diameter of the second pressing plate lower end；Described the first pressing plate, the second pressing plate are formed by two semicircular configurations, and
It is fixedly connected between one pressing plate, the second pressing plate, rubber parts by screw rod with nut.
Above-mentioned technical proposal, utilize the design of the rubber parts between the first pressing plate and the second pressing plate, in compression process, rubber
The lateral wall of glue part is extruded, and because pressure is in the lower surface of roof and lateral wall, then lateral wall generally can be outside
It is convex, while the protruding out between the lateral wall of rubber parts and madial wall on the second pressing plate in compression process, and due to second
The inwall of pressing plate is tilted, then the projection of the second pressing plate and inwall are inwardly extruded the madial wall of rubber parts, realize the interior of rubber parts
The internal diameter of side wall reduces, and the support of the second pressing plate can be realized and huge pressure is produced between the madial wall of rubber parts and cable
Power so that the sealing between rubber parts and cable is more thorough, and stability is more preferable.In summary, in use, rubber parts
Sealing property between pipeline, cable is effectively guaranteed.
Described rubber parts can be made up of other flexible materials.
Be provided with interior concane gap on the inside of the lateral wall of the opening of rubber parts wherein one end, the lateral wall of the other end it is interior
One is extended with before lateral and coordinates fixed projection with interior concane gap.The design of the structure, in use directly by rubber
Part and the first pressing plate, the second pressing plate open rear enclosure on cable, are being put into pipeline, are realizing the envelope to existing cable pipeline
It is stifled, and the design of interior concane gap and projection, it can ensure that the sealing property of rubber parts opening.
First pressing plate, the junction of two semicircular configurations of the second pressing plate are located therein two through holes, and junction
Structure be：Overlapping in junction in two semicircular configurations, described through hole is arranged in overlapping region.The structure makes structure
It is simpler, the rotation of the first pressing plate, the second pressing plate each several part is carried out as rotating shaft using original screw rod.
The appearance of the lateral wall of rubber parts is provided with some annular convex tendons.The design of convex tendon, in the feelings of uniform pressure
Under condition, the contact area between convex tendon and pipeline is small, then its pressure is big, lift-off seal performance.
A kind of cable duct plugging device obtained by the utility model, the compression by the first pressing plate, the second pressing plate are real
The lateral wall extruding of existing rubber parts is outwardly, while the inclined design of the inwall using the second pressing plate, can be by rubber parts
Side wall is inwardly compressed, and realizes and larger pressure is produced between the madial wall of rubber parts and cable, realize better tightness.
