Preferably, the turnover body is a door leaf of a fireproof door, and the fixing frame is a door frame of the fireproof door.

Preferably, the turnover body is a window sash of the fireproof window, and the fixing frame is a window frame of the fireproof window.

Preferably, the section of the fireproof expansion sealing element 7 is long.

Preferably, the sealing strip 11 is arcuate in cross-section.

Further, the arc of the arc is tangent to the arc chamfer on the fixed frame.

Preferably, the fireproof expansion sealing element 7 and the turnover body have a gap, and the gap can be sealed after the fireproof expansion sealing element 7 expands.

The beneficial effects of the utility model reside in that:

1) the sealing strip and the fireproof expansion sealing element are respectively arranged on two sides which are far away from each other, and are clamped with the door plate when the door frame is closed, so that the separation function is achieved.

2) Under the state of firing, the sealing strip is at first on fire to guarantee firework towards the ignition face, can not influence fire prevention inflation sealing member, can not flee the fire to the back of the body fire face yet, the good reliability.

3) Under high temperature state, the fire prevention inflation sealing member inflation plugs up the gap of door frame and door leaf, prevents that fireworks from scurrying to the back of the body fire face, has played the function of fire prevention.

4) In order to ensure the sealing effect, the door frame and the door leaf are tightly attached when being closed, and the part contacted with the sealing strip is specially designed into an arc, so that the door frame and the door leaf are completely contacted with the sealing strip without influencing the tight attachment of the door frame and the door leaf. The sealing and fireproof performance is taken into consideration.
