Fireproof door capable of relieving fire

Abstract

The invention discloses a fireproof door capable of relieving fire. The fireproof door comprises a door frame and a fireproof door body. A connecting bin penetrates through one side of the top end ofthe door frame. A connecting pipe is welded to the top of the connecting bin. Rotating shafts are symmetrically embedded in the bottom of an inner cavity of the connecting bin. Sealing plates are welded to the other sides of the rotating shafts, a clamping groove is embedded in one side of the top end of each sealing plate, a clamping bolt is welded to the other side of the top end of each sealingplate, a fireproof door body is rotationally connected to the inner side of the door frame, hinges are welded to the outer side of the fireproof door body, and the hinges are welded to the door frame. The fireproof door has the advantages that the sealing plates, the clamping grooves, the clamping bolts and a smoke exhaust plate part are arranged, so that when a fire disaster occurs, generated dense smoke can be discharged in time, by means of clamping connection of the clamping grooves and the clamping bolts, the sealing plates can only be turned over towards the outer side, meanwhile, through cooperation with the smoke exhaust plate part, external fresh air is effectively prevented from entering a fire scene while smoke discharging is conducted, and therefore it is guaranteed that the internal fire behavior can be relieved.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a fire door. Background technique [0002] In life, fires are often caused by some improper operations. In buildings with high floors, a fire door will be set up in the escape passage. The fire door can effectively protect the personnel inside the escape passage. As people live With the continuous improvement of quality, the awareness of fire escape also needs to be continuously strengthened. For fire doors, in the event of a fire, they can effectively isolate flames and fire smoke, which is particularly important. [0003] However, the existing fire doors can only prevent the fire from spreading, and cannot effectively alleviate the fire, and when the fire door is opened, oxygen will be injected, causing the fire to approach the fire door, and the fire door will also damaged. Contents of the invention [0004] The purpose of the present invention is to provid...
