Abstract
The utility model discloses a metal protective door reinforcing assembly, which relates to the technical field of fire-resistant doors and comprises a building wall surface and a control box body, an alloy door frame is connected to the outer side of the building wall surface, a door body is hinged to the outer side of the alloy door frame, vertical reinforcing mechanisms are arranged on the upper side and the lower side of the interior of the door body, and the control box body is hinged to the control box body. The vertical reinforcing mechanisms lock the upper side and the lower side of the door body, the anti-impact capacity of the door body is improved, the transverse reinforcing mechanisms are arranged on the left side and the right side of the door body, the transverse reinforcing mechanisms transversely support the hinged position of the door body and the alloy door frame, external personnel are prevented from pushing the door body inwards, and the sealing strength of the door body is improved. In the using process, one face of the door body is limited and positioned through the externally-arranged control box body, assembling and positioning of the door body and the control box body are facilitated, and the maintenance and replacement cost of a machining assembly on one side of the door body is reduced.
