The first partition plate 506 and the second partition plate 507 are adapted to the first connecting groove 516, and the two third partition plates 511 are adapted to the second connecting groove 517, so that when the first partition plate 506 and the second partition plate 507 move, they can move into the door frame 1 through the two first connecting grooves 516, and the two third partition plates 511 can move into the door frame 1 through the two second connecting grooves 517 respectively, thereby achieving the purpose of blocking the gap between the door frame 1 and the door panel 2 by the first partition plate 506, the second partition plate 507 and the two third partition plates 511.

[0035] Reference Figure 3-5 In this embodiment, a first accommodating groove 518 is provided on the first partition 506, and a second accommodating groove 519 is provided on the second partition 507. The first accommodating groove 518 is communicated with the second accommodating groove 519. The transverse gear 502, the vertical gear 503, the first transverse rack 504 and the second transverse rack 505 are all installed in the space formed by the first accommodating groove 518 and the second accommodating groove 519, thereby reducing the space required for the installation of the transverse gear 502, the vertical gear 503, the first transverse rack 504 and the second transverse rack 505, and enabling the first transverse rack 504 and the second transverse rack 505 to be connected to the first partition 506 and the second partition 507 respectively through the top wall of the first accommodating groove 518 and the side wall of the second accommodating groove 519 away from the door panel 2.

[0036] Reference Figure 3-4In this embodiment, movable grooves 520 are provided at the upper and lower ends of the first partition 506 and the second partition 507.

[0037] Reference Figure 5-9 In this embodiment, the cooling mechanism 3 includes an installation groove 301 opened on the door frame 1, an L-shaped water pipe 302 is slidably installed in the installation groove 301, a plurality of nozzles 303 and a plurality of connecting seats 304 are installed on the L-shaped water pipe 302, and the plurality of connecting seats 304 are all slidably installed on the wall surface of the installation groove 301, and a triangular bar 305 is installed on the third partition plate 511 located at the top of the door panel 2, and the triangular bar 305 is located directly below the connecting seat 304.

[0038] When the two third partitions 511 move toward the door frame 1, the triangular bar 305 is driven to move upward, thereby pushing the plurality of connecting seats 304 to move toward the outside of the door frame 1 until the plurality of nozzles 303 move to the outside of the door frame 1. Water is then sprayed through the nozzles 303, thereby achieving the effect of cooling the fire door. At the same time, it helps to achieve a fire extinguishing effect for smaller fires.

[0039] Reference Figure 8 In this embodiment, a plurality of first connection blocks 306 are installed on the wall surface of the installation groove 301, and a plurality of springs 307 are installed on the plurality of first connection blocks 306. The other ends of the plurality of springs 307 are connected to the corresponding connection seats 304, so that after the fire is extinguished, the triangular bar 305 moves downward, eliminating its thrust on the plurality of connection seats 304. At this time, the pulling force of the spring 307 can drive the connection seat 304 to reset, so that the L-shaped water pipe 302 and the nozzle 303 can return to the installation groove 301, thereby completing the retraction of the nozzle 303.

[0040] Reference Figure 7-9 In this embodiment, a slot 308 is provided on the door frame 1, and a push-pull plate 309 is hinged on the slot 308. A plurality of second connecting blocks 310 are installed on the wall of the mounting slot 301. The plurality of second connecting blocks 310 are elastically connected to the push-pull plate 309, so that when the nozzle 303 moves out of the door frame 1, it can contact the push-pull plate 309 and push the push-pull plate 309 to rotate, so that the nozzle 303 is exposed from the door frame 1. When the nozzle 303 moves into the door frame 1, the push-pull plate 309 can be automatically closed by elasticity, thereby preventing external dust from entering the door frame 1 and affecting its internal components.

[0041] Reference Figure 7In this embodiment, a flame retardant expansion sealing strip 6 is installed on the door frame 1. The flame retardant expansion sealing strip 6 is close to the second partition 507, so that the connection between the first partition 506, the second partition 507 and the two third partitions 511 and the door frame 1 can be sealed by the flame retardant expansion sealing strip 6, thereby preventing flames and smoke from entering the door frame 1 through the gaps at the connection and causing damage to the fire door.
