Description
Technical Field
[0001] The utility model relates to a complex technical field, in particular to a fireproof door with a protection mechanism. Background Art
[0002] Fire doors refer to doors that can meet the requirements of fire resistance, integrity and thermal insulation within a certain period of time. They are fireproof partitions with certain fire resistance, such as those installed between fire compartments, evacuation stairwells, vertical shafts, etc. For example, the partition doors of equipment rooms (cylinder rooms, foam stations, etc.) with fixed fire extinguishing devices installed in high-rise civil buildings, ventilation and air conditioning rooms, etc. should use Class A fire doors; the doors on the partition walls of basement rooms where people often stay or there are many combustibles should use Class A fire doors; due to conditions, it is necessary to arrange oil and gas boilers, combustible oil-immersed power transformers, high-voltage capacitors and switches filled with combustible oil in high-rise buildings, and the doors on the partition walls of special rooms should all use Class A fire doors. There are also household doors that are designed with special requirements and must be fireproof, such as the household doors of fire monitoring and command centers, archives and information rooms, and valuables warehouses, which usually use Class A or Class B fire doors. The household doors of high-rise and high-end residential buildings often use fireproof and anti-theft doors. Fire doors are an important component of fire-fighting equipment and an important part of social fire prevention. Fire doors should be installed with fire door closers or door closing devices that allow normally open fire doors to automatically close the door leaves in the event of a fire (except for use in special areas, such as pipe well doors).
[0003] When using existing fire doors, since they need to open and close automatically, it takes a lot of force to open the door. At the same time, in the event of an accident, the door is prone to collide with people when it closes automatically. For this reason, we propose a fire door with a protective mechanism.
