Low-voltage distribution box inlet and outlet wire fireproof blocking device

Abstract

The invention relates to a low-voltage distribution box inlet and outlet wire fireproof blocking device. The low-voltage distribution box inlet and outlet wire fireproof blocking device includes a fixing base, fixing screws, serrated filling foam, a top half arc cover, a lower half arc cover and arc cover connecting screws, wherein the fixing base is annular, the several fixing screws are arrangedon the edge, the center position of the fixing base is fixedly connected with the lower half arc cover, the lower half arc cover and the upper half arc cover are connected by a hinge, the arc cover connecting screws are respectively located at corresponding positions of the upper half arc cover and the lower half arc cover, and the serrated filling foam is disposed inside the upper half arc coverand the lower half arc cover respectively. The device is advantaged in that tight blocking, long-lasting durability, high temperature resistance, rat-proof and insect-proof property, beautiful property, no-easy deformation and easy mounting are achieved, and standard parts blocked at inlet and outlet portions of the low-voltage distribution box can be widely utilized.

Description

technical field [0001] The invention relates to the field of power distribution prevention and protection, in particular to a fire-proof sealing device for incoming and outgoing lines of a low-voltage distribution box. Background technique [0002] The blockage at the inlet and outlet of the traditional low-voltage distribution box is generally blocked by fire-proof plugging cement or fire-proof plugging cement with the aid of partitions. There are the following problems in construction and subsequent operation: (1) Without partitions to assist The fire-proof plugging cement is used for sealing: the plugging cement in this sealing method is easily affected by high temperature factors such as sunlight and has fluidity, and the sealing cement is often deformed and lost after a summer, resulting in cavity sealing failure and thus Lose the functions of fire prevention, moisture resistance, and small animals; (2) Blocking with fire-proof plugging cement assisted by partitions: Th...
