fireproof door

Abstract

The invention discloses a fireproof isolation door, which comprises a door closer and a door body. The door body is a hollow structure. A protection device and a fire isolation device are arranged in the door body. The protection device includes a high-temperature electrification mechanism and a pushing mechanism. The mechanism includes fuse wire, fixed pulley, connecting wire, guide block, metal block, metal sheet 1, metal sheet 2, motor and power supply. One side of the door body is provided with a groove matching the fuse wire, and the upper side of the groove is Fixed pulleys are provided, and the two ends of the fuse are fixedly connected to the two sections of connecting wires respectively; the present invention can work together through the protection device and the door closer, so that the fire isolation door can be pushed open in time to block the fire isolation when a fire occurs. The weight of the door prevents the occurrence of the situation where the fire isolation door does not work in the event of a fire, reduces the danger of thick smoke in the safety passage when a fire occurs, and reduces the temperature in the safety passage to a certain extent.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a fire isolation door. Background technique [0002] The issue of fire safety has always been a matter of close concern to the society. However, because many people lack certain knowledge of fire safety, some people often block the fire isolation door of the safety passage with heavy objects to keep it open all the time. The corridor can be better ventilated, and this behavior will lead to the fact that when a fire breaks out, because the fire isolation door is not closed, dense smoke and high temperature will spread into the safe passage without being blocked, affecting the safety of people in the building when the fire breaks out. The evacuation process may cause casualties in severe cases; [0003] Therefore, we are badly in need of inventing a kind of fire isolation door that can automatically push open and block heavy objects to close the isolation door for fire pre...
