[0034] The present invention will now describe the externally mounted, heat-insulating, nickel-saving stainless steel air-raid shelter door.

[0035] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4The externally mounted, heat-insulated, nickel-saving stainless steel air-raid shelter door includes a door frame 1, an air-raid shelter door body 2, a heat-insulating bracket 3, a heat-dissipating bracket 4, a drive mechanism 5, and a heat-insulating layer 6. The door frame 1 is fixed to the wall; the air-raid shelter door body 2 is openable and closable on the door frame 1; the heat-insulating bracket 3 has an internal heat-insulating cavity; the heat-dissipating bracket 4 is located in the external space of the enclosed space of the air-raid shelter door body 2, and has a heat exchange cavity. The heat exchange cavity and the heat insulation cavity are connected by a connecting pipe 603, and both contain a heat exchange medium 301; the drive mechanism 5 is located on the connecting pipe 603 and is used to drive the heat exchange medium 301 to circulate between the heat exchange cavity and the heat insulation cavity; the heat insulation layer 6 is located on the heat-insulating bracket 3 and is located on the outside of the heat insulation cavity.

[0036] The beneficial effects of the externally mounted heat-insulating nickel-saving stainless steel air-raid shelter door provided in this embodiment are as follows: Compared with the prior art, the externally mounted heat-insulating nickel-saving stainless steel air-raid shelter door provided in this embodiment, through the combination of heat-insulating bracket 3, heat dissipation bracket 4 and drive mechanism 5, can absorb the heat on the outside of the air-raid shelter door body 2 and dissipate it through the heat dissipation bracket 4, thereby improving the heat insulation effect of the air-raid shelter door body 2. Furthermore, by setting the heat insulation layer 6, the heat insulation effect of the heat-insulating bracket 3 can be further improved, thereby improving the heat insulation effect of the air-raid shelter door.

[0037] In this embodiment, the heat-insulating bracket 3 is rectangular in shape. A fixing component is provided between the heat-insulating bracket 3 and the air-raid shelter door body 2. When the fixing component is locked, the heat-insulating bracket 3 is fixed to the air-raid shelter door body 2. The sum of the thickness of the heat-insulating bracket 3 and the thickness of the air-raid shelter door body 2 is equal to the thickness of the door frame 1. The length of the heat-insulating bracket 3 is the same as the length of the air-raid shelter door body 2, and the width of the heat-insulating bracket 3 is the same as the width of the air-raid shelter door body 2. As configured above, on the one hand, the heat-insulating bracket 3 can completely cover the air-raid shelter door body 2, which is convenient for heat insulation of the air-raid shelter door body 2. On the other hand, it can also prevent the heat-insulating bracket 3 from interfering with the door frame 1, making the opening and closing of the air-raid shelter door body 2 smoother.

[0038] Specifically, the fixing component includes multiple first fixing holes, multiple second fixing holes, and multiple fixing screws 302. The first fixing holes, second fixing holes, and fixing screws 302 correspond one-to-one. The first fixing holes are located on the body 2 of the air-raid shelter door and are through holes. The second fixing holes are located on the heat-insulating bracket 3. When the fixing component is locked, the fixing screws 302 are screwed into the corresponding first and second fixing holes. The arrangement of the first fixing holes, second fixing holes, and fixing screws 302 facilitates the installation and disassembly of the heat-insulating bracket 3, and facilitates its use and maintenance.

[0039] As a preferred technical solution, the heat insulation layer 6 includes a vacuum layer 601 and a heat insulation material layer 602 arranged side by side from the inside out. A heat exchange chamber, a vacuum chamber, and a filling chamber are arranged side by side on the heat insulation bracket 3. The vacuum chamber is evacuated to form the vacuum layer 601, and the filling chamber is filled with heat insulation material to form the heat insulation material layer 602. The arrangement of the vacuum layer 601 and the heat insulation material layer 602 can easily improve the heat insulation effect of the heat insulation layer 6, and the structure of the vacuum layer 601 and the heat insulation material layer 602 is simple and easy to use.

[0040] In this embodiment, the connecting pipe 603 is L-shaped and includes a vertically arranged fixed pipe 604 and a horizontally arranged telescopic pipe 605 located at the bottom end of the fixed pipe 604. The top end of the telescopic pipe 605 is connected to the heat exchange chamber. The telescopic pipe 605 is designed to extend when the air defense door body 2 is opened and shorten when the air defense door body 2 is closed, preventing the connecting pipe 603 from interfering with the flipping of the air defense door body 2.

[0041] like Figure 1 and Figure 2 As shown, the heat dissipation bracket 4 is box-shaped, and multiple heat dissipation plates 401 are evenly arranged on the top of the heat dissipation bracket 4. The heat dissipation plates 401 are arranged at an angle. The arrangement of heat dissipation plates 401 can increase the heat dissipation area of ​​the heat dissipation bracket 4, thereby improving the heat dissipation effect of the heat dissipation bracket 4 and improving the heat insulation effect of the heat insulation bracket 3.

[0042] In this embodiment, the heat dissipation bracket 4 is provided with a clearance hole; the inner and outer sides of the air-raid shelter door body 2 are provided with handwheels 201 for opening and closing the air-raid shelter door body 2, and a connecting rod 202 is provided between the handwheels 201. The connecting rod 202 is inserted into the clearance hole, and the handwheels 201 are detachably mounted on the connecting rod 202. The detachable arrangement of the clearance hole and the handwheels 201 facilitates the installation of the heat insulation bracket 3 and prevents interference between the heat insulation bracket 3 and the connecting rod 202.

[0043] like Figure 3 and Figure 4 As shown, a detection mechanism 7 is provided inside the vacuum chamber. The detection mechanism 7 is connected to the drive mechanism 5. The detection mechanism 7 is used to detect the temperature of the side wall of the vacuum chamber and to turn the drive mechanism 5 on or off. The setting of the detection mechanism 7 makes it easy to start or stop the drive mechanism 5 at a preset temperature, which can reduce energy consumption while ensuring the heat insulation effect of the heat insulation bracket 3.

[0044] Specifically, the detection mechanism 7 includes a detection cylinder 701, inside which a slider 702 is slidably mounted. An expansion medium 703 is located on one side of the slider 702, and a push-button switch 704 is located on the other side. The push-button switch 704 is electrically connected to the drive mechanism 5. The expansion medium 703 can expand when heated, pushing the slider 702 to slide until the push-button switch 704 is pressed. In actual use, once the temperature of the sidewall of the vacuum chamber rises, the expansion medium 703 absorbs heat and expands, pushing the slider 702 to slide until the slider 702 presses the push-button switch 704, at which point the drive mechanism 5 is activated. When the temperature of the sidewall of the vacuum chamber decreases, the expansion medium 703 releases heat and contracts, pulling the slider 702 to slide until the slider 702 releases the pressure on the push-button switch 704, at which point the drive mechanism 5 is deactivated.

[0045] Finally, the door frame 1 and the body of the air-raid shelter door 2 are made of nickel-saving stainless steel, which can reduce the thickness and weight of the air-raid shelter door without reducing its protective capabilities, making it easier to use.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
