Detailed Description
The invention is illustrated below with reference to specific examples. It will be understood by those skilled in the art that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention in any way.
A through-wall sealing disc for cables or pipelines is shown in figure 1 and comprises a blind disc through pipe 1, an internal tooth flange 2, a cable airtight joint 3 and an airtight blind plug 4, wherein the blind disc through pipe 1 is embedded in an opening of a wall plate;
the blind disc penetrating pipe 1 comprises a cylindrical pipe body 6 and a blind disc surface 7 which are integrally formed, the blind disc surface 7 is positioned at one end of the cylindrical pipe body 6, an external thread 8 is arranged on the pipe surface at the outer side of the other end of the cylindrical pipe body 6, an airtight gasket 5 is arranged on the inner side surface of the blind disc surface 7, and the airtight gasket 5 is nested on the outer wall of the cylindrical pipe body 6; three inner tooth openings 9 are formed in the blind disc surface 7, and the three inner tooth openings 9 are uniformly distributed by taking the central shaft of the blind disc surface 7 as the center;
the inner-tooth flange 2 is in a circular ring sheet shape, inner-tooth threads 10 matched with outer-tooth threads 9 of the blind plate through pipe 1 are arranged on the inner ring of the inner-tooth flange, so that the inner-tooth flange 2 is in threaded sleeve joint with the outer pipe surface of one end of the blind plate through pipe 1, a plurality of openings 11 for installation and filling are uniformly formed in the disc surface of the inner-tooth flange 2, and the inner-tooth flange 2 is screwed through a tool, so that the wall penetrating closed disc is fixed on a wall plate;
