Description

Technical Field

[0001] The utility model relates to the field of fireproof steel doors, in particular to high-strength shock-absorbing fireproof steel doors. Background Art

[0002] A fireproof steel door is a door specially designed for fire prevention. It is mainly made of steel materials, including door frames, door leaf frames and door leaf panels. In order to achieve the purpose of fire prevention, the inside of the door leaf is usually filled with fireproof and heat-insulating materials that are non-toxic and harmless to the human body, and is equipped with fireproof hardware accessories.

[0003] At present, when using fireproof steel doors, the door leaves are prone to collision with door frames and walls when opening or closing. Due to the lack of shock-absorbing structure, long-term collision of fireproof steel doors will cause the door leaves to deform and reduce the service life of the door leaves, thus affecting the fire protection effect. For this reason, we propose high-strength shock-absorbing fireproof steel doors to solve the above problems. Utility Model Content
