Description

technical field [0001] The invention relates to the mechanical field, in particular to a fire door. Background technique [0002] According to the fire protection regulations, the passages of large shopping malls, hotels, hospitals, and entertainment places are required to install fire doors. Because wooden fire doors are more suitable for secondary decoration, customers often use wooden double-leaf fire doors on the passageway, and the current fire doors are to add fireproof filling layers on the surface materials of fire doors or inside to resist fire sources, which is also important The fire-resistant time of the fire door is not long, and the self-cooling and fire alarm functions of the fire door cannot be realized, which cannot well control the spread of the fire. Therefore, in order to solve the above problems, a new technical solution is provided. Contents of the invention [0003] The object of the present invention is to provide a fire door in order to overcome ...
