Fireproof isolating door

Abstract

The invention discloses a fireproof isolating door. The fireproof isolating door comprises a door closer and a door body which is of a hollow structure, wherein a protective device and a fire insulation device are arranged in the door body; the protective device comprises a high-temperature electrifying mechanism and a pushing mechanism; the high-temperature electrifying mechanism comprises a fusewire, a fixed pulley, a connecting wire, a guide block, a metal block, a metal piece I, a metal piece II, a motor and a power supply; one side of the door body is provided with a groove which is matched with the fuse wire; the upper side in the groove is equipped with the fixed pulley; and the two ends of the fuse wire are fixedly connected to the two sections of the connecting wire separately. The protective device and the door closer can be matched in work, so that the fire isolating door can timely push away a heavy object which blocks the fireproof isolating door while a fire happens, prevents a condition that the fireproof isolating door does not achieve effect during the fire, reduces dense smoke harm in a safety channel while the fire happens, and reduces a temperature in the safety channel to 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...
