Elevator switch box with fireproof function

Abstract

The invention relates to the technical field of elevator switch boxes, and discloses an elevator switch box with a fireproof function. The elevator switch box comprises an outer shell and an inner shell, wherein the interior of the outer shell is fixedly connected with a heat insulation flame retardant layer. According to the elevator switch box with the fireproof function, the outer shell and the inner shell are arranged, the outer shell and the inner shell are made of ceramic silicone rubber materials, the ceramic silicone rubber has the excellent characteristics of fire prevention, flame retardance, low smoke, non-toxicity and the like, residues after combustion are hard, the ceramic shells are not molten and do not drip in a fire disaster environment, and therefore flame retardance of the elevator switch box is better realized, and use is safer. The elevator switch box is provided with a heat-insulation flame-retardant layer and a fireproof coating, the heat-insulation flame-retardant layer has the advantages of being high in strength, resistant to oxidation, low in heat conductivity, small in heat capacity and the like, the fireproof coating protects the elevator switch box against direct contact with air, ignition of the elevator switch box is delayed, the combustion speed is reduced, and therefore the elevator switch box can be better subjected to heat insulation and flame retardance.

Description

technical field [0001] The invention relates to the technical field of elevator switch boxes, in particular to an elevator switch box with a fireproof function. Background technique [0002] An elevator refers to a permanent transportation device that serves several specific floors in a building, and its car runs on at least two rigid rails perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. The elevator switch box allows the user to use The work panel that controls the elevator to move up and down. [0003] In the existing technology, the common elevator switch box does not have the function of fire and flame retardant when it is in use, so the elevator switch box is very vulnerable to damage in the event of a fire. Since the elevator switch box is mostly installed inside the wall, the long After time use, the water in the wall will enter the inside of the elevator switch box, which will cause the inside of the elevator sw...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an elevator switch box with a fireproof function, which has the advantages of good fireproof and flame retardant effect, good waterproof and moistureproof effect, and solves the problem that the elevator switch box does not have the function of fireproof and flame retardant. The elevator switch box is very vulnerable to damage in the event of a fire. Most elevator switch boxes are installed inside the wall. After a long period of use, the water in the wall will enter the inside of the elevator switch box, resulting in damage to the inside of the elevator switch box due to moisture. question
