[0034] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a fireproof door capable of suppressing fire, comprising a door frame 1: a first insulation door panel 2 is movably connected to one side of the door frame 1, a lever mechanism 3 is arranged on one side of the first insulation door panel 2, and a suppression mechanism 4 is arranged on the top of the lever mechanism 3;

[0035] like Figure 3 and Figure 4 As shown, the lever mechanism 3 includes a turntable 301, a slide bar 302, a pin 303, a rotating wheel 304, a first block 305, a second block 306 and an annular block 307. The turntable 301 is movably connected to one side of the first heat-insulating door panel 2, one side of the turntable 301 is movably connected to the slide bar 302, the top of the turntable 301 is movably connected to the pin 303, one side of the turntable 301 is fixedly connected to the rotating wheel 304, one side of the rotating wheel 304 is movably connected to the first block 305, the bottom of the rotating wheel 304 is movably connected to the second block 306, and the second block 306 is movably connected to one side of the annular block 307.

[0036] The lever mechanism 3 also includes a spring 308, a baffle 309, a second thermal insulation door panel 310 and a hinge 311. The spring 308 is fixedly connected to one side of the second block 306. One side of the spring 308 is fixedly connected to the baffle 309. The baffle 309 is fixedly installed on one side of the second thermal insulation door panel 310. One side of the second thermal insulation door panel 310 is provided with a hinge 311.

[0037] The second clamping block 306 is symmetrically arranged longitudinally on one side of the annular clamping block 307 with the rotating wheel 304 as the center, and the first clamping block 305 is transversely arranged on one side of the annular clamping block 307 with the rotating wheel 304 as the center.

[0038] The annular clamping block 307 is fixedly mounted on one side of the second heat insulation door panel 310, the rotating wheel 304 is movably mounted on one side of the second heat insulation door panel 310, a groove is provided inside the first clamping block 305, and a spring 308 is fixedly connected to one side of the groove, and a baffle 309 is movably connected to the other side of the groove.

[0039] What needs to be further explained is that: when it is necessary to close the first heat-insulating door panel 2, the latch pin 303 is pulled upward until it is disengaged from the slide rod 302, and then the slide rod 302 is pulled out to one side to increase the length of the force arm, and then the turntable 301 is driven to rotate clockwise by pulling the slide rod 302. At this time, the turntable 301 drives the rotating wheel 304 to rotate, while the first block 305 and the second block 306 are pushed out of the annular block 307 to one side, until the second block 306 and the annular block 307 are connected between the door frame 1 and the wall, thereby completing the fixation of the first heat-insulating door panel 2.

[0040] like Figure 5 and Figure 6 As shown, the suppression mechanism 4 includes a liquid storage bin 401, a first clamping hole 402, a second clamping hole 403, a first positioning tube 404, a fire-blocking block 405, a second positioning tube 406, a material storage bin 407, a liquid inlet hole 408, a sealing plate 409, an expansion block 410, a heat conducting plate 411, a neutralization bin 412 and a nozzle 413. The liquid storage bin 401 is fixedly connected to the top of the second clamping block 306, the top of the liquid storage bin 401 is provided with a first clamping hole 402, one side of the liquid storage bin 401 is provided with a second clamping hole 403, and the top of the first clamping hole 402 is connected to the first positioning tube 404. A fire-blocking block 405 is provided inside the first positioning tube 404, a second positioning tube 406 is fixedly connected to one side of the second clamping hole 403, a storage bin 407 is movably connected inside the second positioning tube 406, a liquid inlet hole 408 is provided on the top of the storage bin 407, a sealing plate 409 is fixedly connected to one side of the storage bin 407, an expansion block 410 is fixedly connected to the other side of the storage bin 407, a heat conducting plate 411 is movably connected to one side of the expansion block 410, a neutralization bin 412 is connected to the top of the first positioning tube 404, and a nozzle 413 is provided on one side of the neutralization bin 412.

[0041] The shell of the fire-block 405 is a plastic film, and the melting point of the plastic film is 200 degrees Celsius. The interior of the fire-block 405 is filled with a water-based flame retardant, and the interior of the liquid storage tank 401 is filled with a flame retardant foaming agent.

[0042] The interior of the storage bin 407 is filled with a foaming agent initiator, and the expansion block 410 is made of a thermal expansion memory metal, and the expansion temperature of the thermal expansion memory metal is one hundred degrees Celsius.

[0043] It needs to be further explained that: when a fire occurs, the heat conduction plate 411 transfers the temperature to the expansion block 410. After the expansion block 410 expands when heated, it stretches toward the storage bin 407 and pushes the storage bin 407 out of the second positioning tube 406. At this time, the foaming agent in the storage bin 407 contacts the flame retardant foaming agent filled in the liquid storage bin 401, a chemical reaction occurs and the foaming agent expands and foams violently. It enters the neutralization bin 412 through the first positioning tube 404 and carries the fire block 405 with it, and then is sprayed on one side of the first insulation door panel 2 through the nozzle 413. The plastic film on the surface of the fire block 405 decomposes and melts when heated, and the water-based flame retardant in the fire block 405 is exposed to the air and accelerates the reaction under the action of high temperature, volatilizing the flame-retardant gas to suppress the fire.

[0044] The technical solution provided by the utility model is that when a fire-proof door capable of suppressing fire is used, first, when the first heat-insulating door panel 2 needs to be closed, the latch pin 303 is pulled upward until it is disengaged from the slide bar 302, and the slide bar 302 is partially pulled out to one side to increase the length of the force arm, and then the turntable 301 is driven to rotate clockwise by pulling the slide bar 302. At this time, the turntable 301 drives the rotating wheel 304 to rotate, and the first clamping block 305 and the second clamping block 306 are pushed out of the annular clamping block 307 to one side, until the second clamping block 306 and the annular clamping block 307 are clamped between the door frame 1 and the wall, thereby completing the fixing of the first heat-insulating door panel 2;

[0045] When the first heat-insulating door panel 2 needs to be opened, the slide bar 302 is rotated in the opposite direction to drive the turntable 301 and the rotating wheel 304 to reset, and the first clamping block 305 and the second clamping block 306 are reset under the elastic force of the spring 308 and are no longer clamped between the door frame 1 and the wall.

[0046] Finally, when a fire occurs, the heat conduction plate 411 transfers the temperature to the expansion block 410. After the expansion block 410 expands when heated, it stretches toward the storage bin 407 and pushes the storage bin 407 out of the second positioning tube 406. At this time, the foaming agent in the storage bin 407 contacts the flame retardant foaming agent filled in the liquid storage bin 401, a chemical reaction occurs and the foaming agent expands and foams violently. It enters the neutralization bin 412 through the first positioning tube 404, while carrying the fire block 405, and then is sprayed on one side of the first insulation door panel 2 through the nozzle 413. The plastic film on the surface of the fire block 405 decomposes and melts when heated, and the water-based flame retardant in the fire block 405 is exposed to the air and accelerates the reaction under the action of high temperature, volatilizing the flame-retardant gas to suppress the fire.

[0047] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0048] A person skilled in the art will appreciate that all or part of the steps in the above-mentioned embodiment method can be completed by instructing related hardware through a program, and the program can be stored in a computer-readable storage medium, such as ROM / RAM, a disk, an optical disk, etc.

[0049] The above is only a preferred embodiment of the present invention.

These improvements and modifications should also be regarded as the protection scope of the present invention.
