The working principle of the invention is as follows:

the error, the material and the matching relation of each part of the invention all meet the GB12955-2008 fireproof door standard; in addition

The fit clearance between the door plate 13 and the upper frame of the door frame 11 is not more than 3mm;

the gap between the door plates 13 is not more than 3mm;

the movable gap between the door plate 13 and the lower frame of the door frame 11 is not more than 9mm;

the joint surface gap between the door plate 13 and the door frame 11, the joint surface between the door plate 13 and the door frame 11 with a hinge, a lock and an upper frame are not more than 3mm;

the plane height difference between the door frame and the door plate 13 on the opening surface of the door frame 11 is not more than 1mm.

The general state of the invention is normally closed; when the door panel 13 is changed from the open state to the closed state:

the door closer 14 gives power to close the two door plates 13, so that the two door plates 13 are forced to approach the door frame 11 at a certain speed (the rotation speed of the two door plates 13 is approximate and the closing speed and the closing sequence are not needed to be considered);

the door closer 14 belongs to the mature prior art, and can realize one-way opening of the fireproof door;

when the trapezoid block 17 approaches the door frame 11, the door plate 13 continues to rotate until the trapezoid block 17 is completely covered by the door frame 11; in the process, the inclined surface of the trapezoid block 17 is extruded, so that the push rod 20 and the limiting plate 26 move together, the limiting plate 26 slides along the side wall of the installation space 21, the sliding block 24 is driven to slide along the side wall of the limiting plate 26 under the action of the transmission rod 25, and the reset spring 23 is compressed;

the fixed block 33 of the sliding block 24 moves along with the sliding block, the sliding plate 15 is driven to move together by the connecting buckle 27, the sliding plate 15 slides along the shielding plate 19, and then the sliding plate 15 approaches the shielding plate 19 on the other door plate 13 and continues to slide until the sliding plate 15 covers a gap between the two shielding plates 19;

the two sliding plates 15 are close to each other from left to right, and the gaps between the two door plates 13 are covered from front to back, so that the heat insulation sealing performance and other fireproof performances of the invention are ensured, and compared with the traditional joint cover plate, the sealing effect is better.

In particular, in the above embodiment, the connecting buckle 27 and the control block 30 respectively penetrate through two sides of the shielding plate 19, when the two sliding plates 15 are overlapped, both sliding plates 15 contact and cover the control block 30 on the other door plate 13, the inclined surface of the control block 30 is pressed, the moving block 34 moves together with the control block 30, the moving block 34 slides respectively with the fixed block 33 and the fixed shaft 22, and the control spring 29 connected with the moving block 34 is pressed; the magnet 31 approaches the fixed block 33 but is not fully contacted, the distance makes the attractive force between the magnet 31 and the fixed block 33 strong, so that the fixed block 33 tends to approach the moving block 34, and the connecting buckle 27 and the sliding plate 15 also tend to approach the shielding plate 19, namely, in the closed state of the invention, the two sliding plates 15 can overlap each other to cover the gap between the door plates 13, and also tend to approach each other, so that the sealing effect of the door plates 13 is better.

It should be noted that, under the limiting action of the transmission rod 25 and the limiting plate 26, the outer ring of the bearing 28 only rotates relative to the fixed shaft 22 and does not move axially; when the slide block 24 is slid as a whole, the fixed block 33 and the movable block 34 slide synchronously in the sliding direction, but when the slide plate 15 approaches the control block 30, the movable block 34 slides relative to the fixed block 33, and the sliding directions of the both are perpendicular, so that the sliding directions of the slide block 24 as a whole do not collide with each other, and the sliding direction of the movable block 34 relative to the fixed block 33 slides back and forth with reference to fig. 6.

When the invention is opened from the closed state by a person, the principle is the same as the above process; when the slide plate 15 is separated from the control block 30 and the trapezoid block 17 is separated from the door frame 11, the slide plate 15 is immediately reset by the control spring 29 and the return spring 23, and the state of pressing each other and the state of closing the door gap are released.
