Problems solved by technology

[0003] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: the use of stuffing boxes will lead to the use of stuffing boxes of different specifications for cables with different outer diameter specifications, and it is difficult to achieve standardized construction; If the gap between them is blocked, the construction volume of the fireproof mud plugging work will be relatively large, and the hardening time of the fireproof mud will be longer.

Abstract

The invention discloses a cable sealing device, and belongs to the field of cable installation. The cable sealing device comprises: an expandable inner ring mechanism, an expandable outer ring mechanism and a connecting ring which are concentric; the outer circumferential wall of the expandable inner ring mechanism is in seal connection with the inner circumferential wall of the connecting ring, the inner circumferential wall of the expandable outer ring mechanism is in seal connection with the outer circumferential wall of the connecting ring, the expandable inner ring mechanism is hooped ona cable, and the expandable outer ring mechanism is used for abutting against the inner circumferential wall of a cable penetrating hole. The cable sealing device provided by the embodiment of the invention can adapt to gap sealing between cables with different sizes and cable through holes with different sizes, and is simple and convenient to construct.

Description

technical field [0001] The invention relates to the field of cable installation, in particular to a cable sealing device. Background technique [0002] At present, in the construction of cables passing through walls, it is usually necessary to use stuffing boxes or fireproof mud to seal the gap between the cables and the perforations, so as to realize the gap protection after the cables pass through the walls. [0003] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: the use of stuffing boxes will lead to the use of stuffing boxes of different specifications for cables with different outer diameter specifications, and it is difficult to achieve standardized construction; If the gap between them is blocked, the construction volume of the fireproof mud plugging work is relatively large, and the hardening time of the fireproof mud is longer. Contents of the invention [0004] The embodimen...
