Problems solved by technology

[0002] After the building is completed, a large number of doors need to be installed. These doors can be used for shelter, and can also be used to maintain the temperature inside the house, preventing the outside wind from blowing into the house. In the traditional door manufacturing process, wooden doors are used. The outer surface of these wooden doors is not strong enough to resist the impact of the outer surface well, and cannot guarantee the safety of people and property inside the door, so the strength of the steel wooden door is better

Description

technical field [0001] The invention relates to a door frame, in particular to a door frame of a safety fire door. Background technique [0002] After the building is completed, a large number of doors need to be installed. These doors can be used for shelter, and can also be used to maintain the temperature inside the house, avoiding the outside wind from blowing into the house. In the traditional door manufacturing process, wooden doors are used. Doors, the outer surface of these wooden doors is not strong enough to resist the impact of the outer surface well, and cannot guarantee the safety of people and property inside the door, so the strength of the steel wooden door is better. Contents of the invention [0003] The object of the present invention is to provide a door frame of a safety fire door with reasonable structure and good ventilation effect. [0004] The technical solution of the present invention is: a door frame of a safety fire door, provided with an uppe...
