[0009] The fixing sleeve is fitted onto the hole, with the external thread section located outside the wall of the distribution cabinet and the annular edge located inside the wall of the distribution cabinet.

[0010] One end of the threaded sleeve is provided with a third through hole, and the inner wall surface of the threaded sleeve is provided with an internal thread, which mates with the external thread section.

[0011] There are two card blocks, each of which is semi-circular in shape.

[0012] The two ends of the card block have connecting edges, and a fourth through hole is provided on the connecting edges; multiple elastic blocks are connected to the arc-shaped inner wall surface of the card block, and the elastic blocks can absorb external vibrations; the ends of the elastic blocks are connected to arc-shaped abutting surfaces, and fireproof putty is applied to the arc-shaped abutting surfaces; the two ends of the card block are respectively provided with semi-circular locking slots, which cooperate with the connecting rod.

[0013] Specifically, the first through hole, the second through hole, and the third through hole are all provided with rounded chamfers.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model uses a sealing unit to seal the holes in the power distribution cabinet, preventing the fireproof putty from falling off, achieving a stable sealing effect, and ensuring the normal operation of the power distribution cabinet. Attached Figure Description
