Fireproof theftproof steel wooden door opened in one direction

Abstract

The invention discloses a single-open fireproof and anti-theft steel wooden door, which comprises a door leaf, a hinge, a peephole, and a combination lock. A temperature sensor is installed in a galvanized composite anti-theft steel plate on the inner side of the door leaf. The filler is made of fire-proof and heat-insulating materials. The hinges and combination locks are made of all metal. The combination lock is an anti-pry combination lock. The semiconductor refrigerator and fire extinguisher are electrically connected to the control device, data processing device and the temperature sensor. Double-layer The plank wraps the galvanized composite anti-theft steel plate. The beneficial effects achieved by the present invention are: the filler in the door leaf is made of fire-proof and heat-insulating materials, which is healthy and economical. When a fire occurs, the semiconductor refrigerator installed around the combination lock will reduce the temperature, and the steel plate next to it will not expand due to heat. To ensure the normal use of the combination lock, the temperature sensor in the door leaf senses the temperature change, and when a certain temperature is reached, the fire extinguisher will be activated to extinguish the fire, avoiding the long-term burning of the fire.

Description

technical field [0001] The invention relates to a fireproof door, in particular to a single-open fireproof and anti-theft steel and wood door. Background technique [0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of people. Fire doors are generally divided into steel fire doors and wooden fire doors. Steel fire doors are moderate in price, but they are heavy in weight, laborious to open, monotonous in style, and not beautiful enough. Therefore, they are mostly used in industrial buildings and ordinary civil buildings, o...

Problems solved by technology

[0003] However, if there is a fire, the steel plate will expand due to heat, and the set combination lock will not be able to open normally, which may lock people in the room. In addition, if you want to minimize the loss of things in the room, you may stay in the room to fight the fire. There will be danger to life, and no matter what kind of fire door, its fire protection time is limited. If it is not found in time, the fire may burn to other places
