[0001] The present application relates to the technical field of fire doors, and in particular to an elevator fire door. Background Art

[0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with a certain degree of fire resistance installed in fire compartments, evacuation stairwells, vertical shafts, etc. It is specifically used to isolate fire sources in residential buildings and plays a huge role in fire fighting. Once a fire occurs, people can get a chance to escape through a fire door.

[0003] An existing patent (publication number: CN216737108U) discloses an elevator fire door. The elevator fire door comprises: a door body; a smoke treatment structure, the smoke treatment structure being disposed on the door body and comprising a housing, a water tank, a smoke collection box, a suction pump, a cooling pipe, a smoke guide pipe, a filter screen, a filter layer, a heat dissipation fan, a smoke exhaust pipe, and a smoke sensor. The utility model provides an elevator fire door that, by providing a smoke treatment structure, is primarily used to treat smoke in the event of an elevator fire. The suction force generated by the suction pump continuously absorbs the smoke, which then passes through the filter screen, filter layer, cooling pipe, water tank, and other mechanisms to effectively filter and cool the smoke. This significantly reduces the risk of smoke to passengers in the elevator car, provides excellent protection for people in the event of a fire, and significantly increases the safety performance of the fire door.

[0004] During use, the above-mentioned documents can process the smoke in the bridge compartment through the cooperation of the filter, filter layer and suction pump, but the overall protection is weak and the ability to isolate heat is poor, which affects the fire prevention effect. Utility Model Content

[0005] In response to the deficiencies in the prior art, the present application provides an elevator fire door with advantages such as improved practicality, and solves the problems raised in the background technology.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: an elevator fire door, comprising two door bodies, both of which are equipped with insulation frames on the front side, both of which are provided with cavities inside, both of which are provided with multiple storage slots inside, and both of which are provided with multiple connecting holes on the inner walls of the multiple storage slots, which are connected to the cavities adjacent to them, and both of which are equipped with heat-conducting parts inside, which are fixedly connected to the insulation frames adjacent to them, and a fireproof sealing strip is provided between the two insulation frames.

[0007] Through the above solution, the flame retardant and the heat conductor can transfer the external temperature to the storage tank, so that the flame retardant in the storage tank is vaporized and filled into the cavity, thereby achieving higher fire protection performance.

[0008] Furthermore, the upper ends of the plurality of storage tanks are threadedly connected with sealing covers.

[0009] Through the above solution, installing the sealing cover can add new flame retardant into the storage tank, which is convenient for recycling.

[0010] Furthermore, rock wool insulation boards are installed inside the two door bodies, and the two rock wool insulation boards are symmetrical.

[0011] Through the above scheme, the rock wool insulation board has the characteristics of high temperature, high strength and high flame retardancy, and at the same time has the advantages of low density, good thermal insulation effect, flame retardancy, sound absorption and corrosion resistance.

[0012] Furthermore, the two door bodies are both made of aluminum alloy.

[0013] Through the above scheme, the installation of the aluminum alloy door body can completely block the heat transfer between indoor and outdoor temperatures, achieving a good thermal insulation effect.

[0014] Furthermore, the two heat insulation frames are both made of high temperature resistant steel.

[0015] Through the above solution, high temperature resistant steel can have excellent high temperature resistance, as well as anti-oxidation and anti-corrosion properties.

[0016] Furthermore, the plurality of heat-conducting components are all made of heat-conducting aluminum.

[0017] Through the above solution, the provision of the heat conducting member can facilitate the transfer of external heat to the storage tank, so that the heat on the heat conducting member is transferred to the flame retardant, causing the flame retardant to vaporize.

[0018] Furthermore, the fireproof sealing strip is made of TPV material.

[0019] Through the above scheme, it has good weather resistance and high and low temperature resistance, expands when encountering fire, and can effectively seal and reduce noise and smoke.

[0020] Furthermore, the plurality of storage tanks are distributed at equal distances.

[0021] Through the above solution, the flame retardant can be stored in the storage tank, and the storage tank can be closed by the cooperation of the sealing cover. At the same time, the flame retardant can be filled into the storage tank by opening the sealing cover.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0023] This elevator fire door can transfer the external temperature to the storage tank with the cooperation of the heat conductor by placing aluminum hydroxide flame retardant in the storage tank. Since the flame retardant is placed in the heat conductor, when the heat conductor is overheated, the flame retardant will decompose at high temperature to generate water and release heat. The water vapor generated by the decomposition plays an important role in flame retardancy, thereby achieving the purpose of isolating heat and having fire prevention capabilities, thereby improving overall practicality.

The aluminum alloy door body 1 can completely block the heat transfer between indoor and outdoor temperatures, achieve good thermal insulation and heat insulation, fire prevention effects, and can withstand high temperatures from the outside, thereby reducing the outside temperature from being transferred to the bridge compartment. The two insulation frames 2 are both made of high-temperature resistant steel. High-temperature resistant steel can have excellent high temperature resistance, and at the same time have anti-oxidation and anti-corrosion properties, thereby improving the overall practicality.

[0033] See also Figure 1 、 Figure 2 and Figure 4, multiple heat conducting members 6 are all made of heat conducting aluminum. The provision of heat conducting members 6 can facilitate the transfer of external heat to the storage tank 4, so that the heat on the heat conducting member 6 is transferred to the flame retardant, causing the flame retardant to vaporize. The fireproof sealing strip 7 is made of TPV material, which has good weather resistance and high and low temperature resistance.

The water vapor generated by the decomposition plays an important role in flame retardancy. The water vapor can enter the cavity 3 through multiple connecting holes 5, so that the cavity 3 can be filled with more water vapor. By filling the wall 3 with water vapor, the insulation frame 2 can have a higher high temperature resistance, thereby achieving the purpose of isolating heat and having fire prevention capabilities, thereby improving the overall practicality, and by installing the fireproof sealing strip 7, it can cooperate with the two door bodies 1 to make it have good weather resistance and high and low resistance.
