Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The present invention will now be described in detail with reference to the accompanying drawings.

The utility model provides a prevent fire door with initiative smoke protection effect, includes door frame 1 and articulates prevents fire door 2 on door frame 1, it has smoke protection plate 4 to prevent sliding connection in the recess 3 that 2 four sides of fire door were seted up, smoke protection plate 4 carries out the shutoff to the crack through the drive arrangement drive simultaneously, elastic connection's blocking piece 6 can carry out the shutoff to 1 four corners department of door frame in the cavity 5 that smoke protection plate 4 both ends were seted up.

As shown in fig. 1-5, under the condition of no danger, the fire door 2 is in a closed normal state, when a fire disaster generates dense smoke, a driving device inside the fire door 2 pushes the smoke-proof plate 4 to block the gap, after the smoke-proof plate 4 is pushed out of the groove 3, the blocking blocks 6 elastically connected with the two ends of the smoke-proof plate pop out of the cavity 5 under the action of elasticity, so as to block the four corners of the door frame 1 and prevent smoke from diffusing.
