[0018] Please see Figures 1-4 This utility model provides the following technical solution: a heat-resistant aluminum foil lunch box, including an outer heat-insulating box 1 and an inner aluminum foil storage box 2. The outer heat-insulating box 1 is fixedly connected to the inner cavity of the inner aluminum foil storage box 2, and a hollow heat-insulating chamber 11 and an installation chamber 12 are formed between the outer heat-insulating box 1 and the inner aluminum foil storage box 2. The installation chamber 12 is located above the hollow heat-insulating chamber 11. Reset springs 31 are embedded on both sides of the upper end of the outer heat-insulating box 1, and an outer limiting plate 3 is fixedly connected to the bottom of the reset springs 31. A connecting plate 32 is fixedly connected inside the installation chamber 12, and an inner limiting plate 33 is fixedly connected to the bottom of the connecting plate 32. A transfer plate 4 is inserted inside the installation chamber 12, and a limiting groove 41 is opened inside the transfer plate 4. The position of the limiting groove 41 corresponds to the position of the inner limiting plate 33. A sealing cover 5 is provided on the top of the outer heat-insulating box 1, and installation limiting plates 51 are inserted on both sides of the sealing cover 5. One end of the installation limiting plate 51 extends into the interior of the installation chamber 12.
[0019] In this implementation scheme: the outer heat-insulating box 1 and the inner aluminum foil storage box 2 form the overall frame of the entire lunch box. The hollow heat-insulating chamber 11 located between the outer heat-insulating box 1 and the inner aluminum foil storage box 2 serves as heat insulation. The installation chamber 12 provides installation space using the outer limit plate 3 and the inner limit plate 33. The return spring 31 is used to adjust the position of the outer limit plate 3, and the connecting plate 32 is used to provide a connecting carrier for the inner limit plate 33. At this time, the outer limit plate 3 is formed by the cooperation of the return spring 31, the connecting plate 32, and the inner limit plate 33. Below, a limiting component is formed to limit the movement of the transfer plate 4 after installation. When it is necessary to remove the lunch box from the heating environment, the transfer plate 4 can be inserted into the installation chamber 12, and the entire lunch box can be removed from the heating environment by the transfer plate 4. During the process of removing the entire lunch box outward by the transfer plate 4, when the transfer plate 4 moves upward inside the installation chamber 12, the limiting groove 41 can be fitted onto the outside of the inner limiting plate 33. At this time, the inner limiting plate 33 can limit the movement of the transfer plate 4 in the installation chamber. The internal limiting mechanism of plate 12 helps stabilize the lunchbox when it is moved outward by the transfer plate 4. The sealing cover 5 on the top of the outer insulation box 1 seals the entire lunchbox. The mounting limiting plate 51 inside the sealing cover 5 provides a connecting carrier between the outer insulation box 1 and the sealing cover 5. When the entire lunchbox is in use, it can provide insulation between the inner and outer compartments of the entire lunchbox under the action of the hollow insulation chamber 11. With the cooperation of the transfer plate 4, the outer limiting plate 3, and the inner limiting plate 33, a gripping area is provided for the user when taking the entire lunchbox out of the high-temperature heating environment or moving the lunchbox in a high-temperature state. The transfer plate 4 is detachably connected to the entire lunchbox, which allows the transfer plate 4 to be separated from the high-temperature environment during the heating process, so that the transfer plate 4 is at room temperature when moving the entire lunchbox, preventing the user from being burned when moving the lunchbox.
[0020] Both sides of the outer heat insulation box 1 are provided with embedding grooves 312, and the reset spring 31 is installed inside the embedding groove 312; wherein the embedding groove 312 is used to provide space for the reset spring 31 and the outer limiting plate 3 to be installed.
[0021] Magnetic plates 34 are fixedly connected to the inside of the embedding groove 312 and the inner wall of the mounting chamber 12. Magnetic plates for adsorption are fixedly connected to both sides of the sealing cover 5 to cooperate with the magnetic plates 34. The magnetic plates 34 are used to limit and fix the sealing cover 5 to the embedding groove 312 and the inside of the mounting chamber 12, preventing the sealing cover 5 from falling off from the top of the outer heat insulation box 1.
[0022] An anti-slip pad 311 is fixedly connected to the bottom of the outer limiting plate 3; the anti-slip pad 311 is used to increase the friction between the plate and the transfer plate 4.
[0023] An outer heat insulation sleeve 21 is fixedly connected to the outside of the inner aluminum foil storage box 2; the outer heat insulation sleeve 21 serves to insulate heat.
[0024] A rubber sealing ring 53 is fixedly connected to the bottom of the sealing cover 5; the rubber sealing ring 53 serves to seal.
[0025] The outer end of the sealing cover 5 is fixedly connected to a limiting seat 52; the limiting seat 52 plays a limiting role.
[0026] The working principle and usage process of this utility model are as follows: During the use of the lunch box, when it is necessary to transfer the lunch box from a high-temperature environment to an external environment, the transfer plate 4 can be inserted into the installation chamber 12, and the entire lunch box can be taken out of the heated environment by the transfer plate 4. When the entire lunch box is taken out of the external environment by the transfer plate 4, as the transfer plate 4 moves upward inside the installation chamber 12, the limiting groove 41 can be fitted onto the outside of the inner limiting plate 33. At this time, the inner limiting plate 33 can limit the transfer plate 4 inside the installation chamber 12, and then the user can complete the transfer of the lunch box by the transfer plate 4. When it is necessary to seal the tableware, the sealing cover 5 is placed on the top of the outer heat insulation box 1, and the installation limiting plate 51 is inserted into the installation chamber 12. At this time, the installation limiting plate 51 can be limited inside the installation chamber 12 by the magnetic suction plate 34.
