Detailed Implementation

[0014] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0015] Example: A high-compression-resistant cable fire-sealing device, such as... Figs. 1-3 As shown, it includes a top cover 1 and a bottom cover 2, which are fitted together. A cable through hole 253 is provided in the middle of the side facing each other of the top cover 1 and the bottom cover 2. Multiple sealing gaskets 4 are provided on the inner ring of the top cover 1 and the bottom cover 2 facing each other. A cable sleeve 3 is inserted into the inlet of the cable through hole 253.

[0016] The top cover 1 and the bottom cover 2 are oppositely arranged, and the top cover 1 and the bottom cover 2 are the same in structure, the bottom cover 2 comprises a sealing sleeve 21, a limiting ring 23 and a sealing plug-in seat 25, a plurality of first positioning holes 22 are formed on the front surface of the sealing sleeve 21, a plurality of second positioning holes 231 are formed on the outer ring of the front surface of the limiting ring 23, a plurality of first positioning pins 233 corresponding to the first positioning holes 22 are arranged on the back surface of the limiting ring 23, a second positioning pin 24 is inserted into each second positioning hole 231, the second positioning pin 24 extends to the outer surface of the sealing sleeve 21, the sealing plug-in seat 25 is inserted into the inner cavity of the limiting ring 23, a first inclined surface 232 is formed on the inner ring of the front surface of the limiting ring 23, a flared portion 254 corresponding to the first inclined surface 232 is arranged on the outer ring of the sealing plug-in seat 25, a threading hole 253 is formed in the sealing plug-in seat 25, a second inclined surface 251 is formed on the front surface of the sealing plug-in seat 25 corresponding to the threading hole 253, an insertion cavity 252 is formed on the inner ring of the second inclined surface 251 along the outer ring of the threading hole 253, and the cable sleeve 3 is inserted into the insertion cavity 252.
