As shown in fig. 1-6, a fire door for a building includes a door panel 101 and a door frame 405, wherein a door closer is installed on the door panel 101, so that the door panel 101 can be automatically closed, or the door panel 101 can be directly pushed by manpower to be closed. The base 201 is installed at the upper end and/or the lower end of the door panel 101, and according to the use scene, the base 201 may be installed only at the upper end of the door panel 101, the base 201 may be installed only at the lower end of the door panel 101, and the base 201 may be installed at both the upper end and the lower end of the door panel 101. The base 201 is provided with a middle through groove 205 at one end which is far away from the door plate 101, a pressing rod 207 is slidably arranged in the middle through groove 205, and the pressing rod 207 is as long as the door plate 101. A first spring 206 is connected between the compression bar 207 and the bottom of the middle through groove 205, and a first rubber sealing strip 210 is arranged at one end of the compression bar 207 away from the first spring 206. When the door plate 101 is closed, the compression bar 207 extends out of the middle through groove 205, and the first rubber sealing strip 210 is attached to the door plate 101 under the action of the elastic force of the first spring 206, so that the effect of blocking smoke dust is exerted.
A lock mechanism is provided in the base 201, and a drive mechanism is provided in the door frame 405. When the door panel 101 is opened, the driving mechanism is used for driving the pressing rod 207 to retract into the middle through groove 205, the first spring 206 is in a compressed state at the moment, and the locking mechanism is used for fixing the pressing rod 207 at the moment; when the door panel 101 is closed, the locking mechanism releases the lever 207 at this time, and the lever 207 extends out of the through slot 205 under the action of the first spring 206. By retracting the compression bar 207 into the through groove 205 when the door panel 101 is opened, the compression bar 207 is extended again when the door panel 101 is closed, so that the first rubber sealing strip 210 mounted on the compression bar 207 exerts a sealing effect, and the sealing effect is prevented from being reduced due to the fact that the sealing strip is extruded and worn when the door panel 101 is in the opened state.
Specifically, the cross section of the door frame 405 is L-shaped, and the inner side surface of the door frame 405 in the vertical position is provided with a bump 407. The base 201 is provided with a transverse sliding groove 301 corresponding to the convex block 407 on the side close to the vertical inner side surface of the door frame 405.

The rotating shaft 306 is fixedly connected with a rotating rod 305 and a buckling rod 303. The plunger 207 has a catch 211 on a side thereof adjacent the mounting cavity 307.
When the door panel 101 is closed by a door closer or by manpower, the protrusion 407 pushes the slider 302, the sliding slider 302 pushes the rotating rod 305 to rotate by the push rod 304, so as to drive the rotating shaft 306 to rotate, at this time, the rotating fastening rod 303 leaves the clamping groove 211, the pressing rod 207 extends out of the middle through groove 205 under the action of the elastic force of the first spring 206, and the first rubber sealing strip 210 presses against the door frame 405. At this time, the torsion spring is deformed, but the torsion spring is deformed due to a force or a human force applied by the door closer is sufficiently large, and is always in a deformed state in a closed state due to the door panel 101 being locked.
When the door panel 101 is opened, the driving mechanism is used for driving the pressing rod 207 to retract into the middle through groove 205, at the moment, the protruding block 407 leaves the transverse sliding groove 301, the sliding block 302 is not pushed by the protruding block 407, the torsion spring is recovered from a deformed state, under the action of the torsion spring, the rotating rod 305 pushes the sliding block 302 to return, the rotating clamping rod 303 stretches into the clamping groove 211, although the first spring 206 is in a compressed state, the elastic force exerted by the first spring 206 is insufficient to deform the torsion spring, so that the rotating shaft 306 cannot rotate, the pressing rod 207 is fixed in the middle through groove 205 under the blocking action of the clamping rod 303, and the first rubber sealing strip 210 mounted on the pressing rod 207 cannot stretch out of the middle through groove 205, so that the first rubber sealing strip 210 playing a sealing role is prevented from being stepped and scratched in the door opening state.

When the door panel 101 is in the closed state, the upper portion of the abutment 401 protrudes into the accommodation groove 212. When the door panel 101 is opened, the third inclined surface 213 contacts with the first inclined surface 402, and since the elastic force applied by the second spring 404 is greater than the elastic force applied by the first spring 206, the pressing rod 207 is pushed to retract into the middle through groove 205 and is fixed under the action of the locking mechanism, when the door panel 101 is opened continuously, the abutment 401 is pressed by the door panel 101 to retract into the vertical sliding groove 406, and when the door panel 101 is completely separated from the door frame 405, the abutment 401 is popped up again. When the door is closed, the fourth inclined surface 214 contacts the second inclined surface 403, and the second spring 404 can be pressed due to the force or manpower applied by the door closer, the abutment 401 can retract into the vertical sliding groove 406, and after the door panel 101 is completely closed, the abutment 401 can pop up under the action of the second spring 404, so that the upper portion of the abutment extends into the accommodating groove 212.
