AI Technical Summary

Technical Problem

After the existing fire door is closed, the smoke generated by combustion can flow through the gaps in the door, causing toxic smoke to enter the room, threatening the safety of indoor personnel.

Method used

A fireproof door with smoke barrier function was designed. By setting up a closed groove, a frame-shaped groove, an electric push rod, a frame and a sealing pad, the work of the electric push rod is used to push the sealing pad into the sealing groove, and combining the sealing frame, connecting groove and a folding sealing door, an effective smoke barrier is achieved.

Benefits of technology

Abstract

The fireproof door with the smoke blocking function comprises a door frame, a door body is hinged to the inner wall of the door frame through a set of hinges, a sealing groove is formed in the right side face of the door body, a frame-shaped groove is formed in the left side face of the door frame, and two sets of electric push rods are installed on the inner wall of the frame-shaped groove. The left ends of the two electric push rods are jointly and fixedly connected with an insertion frame, the left side face of the insertion frame is fixedly connected with a sealing pad, and the inner wall of the door frame is fixedly connected with a sealing frame. According to the device, the sealing groove, the frame-shaped groove, the electric push rod, the inserting frame and the sealing pad are matched, the inserting frame can push the sealing pad to enter the sealing groove through work of the electric push rod, the sealing pad can make contact with the inner wall of the sealing groove, and therefore the sealing effect is achieved; and after the folding air-tight door is unfolded, the sealing frame can be sealed, so that the smoke blocking effect is further improved, and the safety is effectively improved.
