[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] Reference Figures 1-6As shown, this utility model provides a special cold-chain storage box for pre-prepared food, including a box body 1, a base 2 disposed at the bottom of the box body 1, and a top cover 3 rotatably disposed at the top of the box body 1. The top cover 3 is tightly fitted with the top of the box body 1 to form a closed space, ensuring the stability of the internal environment. The box body 1 serves as the main container for cold-chain transportation of pre-prepared food, used to contain and preserve the pre-prepared food, ensuring that it remains at a low temperature during transportation. The inner side wall of the box body 1 is also provided with an insulation structure 15 for heat preservation. The insulation structure 15 utilizes the properties of the insulation material to reduce heat transfer, thereby maintaining a constant internal temperature. A sliding groove 11 is provided on the inner wall of the box body 1, and a divider 16 is also provided inside the box body 1 for dividing the internal space of the box body 1. The divider 16 can slide in the sliding groove 11. The chute 11 provides a sliding track for the divider 16, allowing the divider 16 to flexibly adjust its position inside the refrigerator. The divider 16 consists of two intersecting plates, with four dividing plates 161 symmetrically arranged at the center of the divider 16. Several through slots 1611 are evenly distributed on the dividing plates 161. The divider 16 divides the internal space of the refrigerator body 1 into multiple small areas, which is convenient for storing pre-prepared dishes in categories. The through slots 1611 allow air circulation while maintaining the separation between different pre-prepared dishes.

[0027] The divider 16 consists of two intersecting plates, and the divider 16 divides the main body 1 of the refrigeration box into upper and lower bases 2 through the dividing plate 161. Each layer has several small cavities, which makes the internal space of the refrigeration box 1 reasonably divided and the space utilization rate is high. Different pre-prepared dishes can be placed separately, while avoiding the pre-prepared dishes from being stacked in the refrigeration box 1. It also makes it convenient for staff to classify and put them away later.

[0028] Several through slots 1611 are provided on the dividing plate 161 to facilitate the conduction of cold air in the lower space of the preservation box body 1 to the upper space of the preservation box body 1, so as to avoid the temperature of the upper space being too high and causing the pre-cooked food to spoil.

[0029] The insulation structure 15 includes an insulating foam pad 151 adhered to the inner wall of the food storage container body 1 for heat preservation. A buffer plate 152 is also adhered to the inner side of the insulating foam pad 151. The insulation structure 15 provides effective heat preservation, reducing heat exchange between the inside of the food storage container and the outside environment, thereby maintaining a constant internal temperature. The insulating foam pad 151 is typically made of materials with low thermal conductivity, such as polyurethane foam or polystyrene foam. These materials contain a large number of tiny air bubbles, which can block the heat transfer path, thus achieving the heat preservation effect.

[0030] The top cover 3 can rotate and cover the top of the refrigerator body 1. When the top cover 3 is closed, it fits tightly against the top of the refrigerator body 1, forming a closed space. A hook 31 is bolted to the front of the top cover 3, and latches 12 are symmetrically bolted to the front of the refrigerator body 1. The latches 12 cooperate with the hook 31 to lock the top cover 3. When the top cover 3 is closed, the hook 31 will hang at the corresponding position on the front of the refrigerator body 1. At this time, the user can lock the hook 31 by operating the latches 12, thus ensuring that the top cover 3 will not be accidentally opened.

[0031] The refrigerator body 1 has a drain outlet 18 located near the bottom on the back for drainage. When moisture is generated inside the refrigerator (such as condensation due to temperature differences), this moisture flows along the internal structure of the refrigerator to the drain outlet 18 and is discharged outside the refrigerator through the drain outlet 18. A plug 181 is screwed onto the drain outlet 18. When drainage is needed, the user can rotate or remove the plug 181 to allow the drain outlet 18 to flow smoothly; when drainage is not needed, the user can rotate the plug 181 back to its original position or reinstall it to seal the drain outlet 18.

[0032] Handles 13 are bolted to both sides of the exterior of the food storage box body 1. A sleeve 14 is also fixed to the exterior of the food storage box body 1 near one of the handles 13. A sliding rod 141 is slidably arranged in the sleeve 14, and a handle 142 is fixed to the top of the sliding rod 141.

[0033] The inside of the food storage box 1 is fixed with a dividing strip 17, which divides the food storage box 1 into four cavities. Ice packs 4 are placed in the four cavities divided by the dividing strip 17.

[0034] Ice packs 4 are typically filled with freezing gel or refrigerant and are designed to be reusable. They are placed in the cavities divided by the divider 17, and when the temperature inside the refrigerator is high, the ice packs 4 release cold air to lower the temperature.

[0035] Mounting holes 19 are provided at the four corners of the bottom of the food storage box body 1. Several limiting grooves are provided on the mounting holes 19. Magnetic suction parts 191 are also installed in the mounting holes 19. The top of the base 2 is also equipped with plugs 22 that cooperate with the mounting holes 19. Protrusions that cooperate with the limiting grooves are provided around the plugs 22. Universal wheels 21 for moving the food storage box body 1 are symmetrically provided at the bottom of the plugs 22.

[0036] When in use, the base 2 can be installed at the bottom of the refrigerator body 1, and the handle 142 can be pulled out from the slide bar 141 to facilitate the movement of the refrigerator body 1. When not in use, the base 2 can be removed, which makes it easy to stack multiple refrigerator bodies 1 for subsequent transportation.

[0037] Working principle: In use, the dividing strip 17 is installed in the body 1 of the refrigerator, dividing the space inside the body 1. Then, the ice pack 4 is placed in the body 1. Subsequently, the divider 16 is placed in the body 1. The divider 16 consists of two intersecting plates, and the dividing plate 161 on the divider 16 divides the body 1 into upper and lower bases 2. Each layer has several small cavities, making the internal space of the body 1 reasonably divided and maximizing space utilization. Different pre-prepared dishes can be placed separately, while avoiding the stacking of pre-prepared dishes in the body 1. It also facilitates subsequent sorting and retrieval by staff. The dividing plate 161 has several through slots 1611, which facilitate the conduction of cold air from the lower space of the body 1 to the upper space of the body 1, preventing... The excessively high temperature in the upper space causes the pre-cooked food to spoil. The top cover 3 seals the main body 1 of the refrigerator. The handles 13 at both ends of the main body 1 facilitate handling by staff. A detachable base 2 is used, which is magnetically connected to the main body 1. When in use, the base 2 can be installed at the bottom of the main body 1, and the handle 142 can be pulled out from the slide bar 141 to facilitate the movement of the main body 1. When not in use, the base 2 can be removed, which allows multiple main bodies 1 to be stacked for easy transportation. The insulation foam pad 151 and the buffer plate 152 keep the main body 1 warm, preventing the internal temperature of the refrigerator from rising too quickly and causing the pre-cooked food to spoil. The drain 18 drains the condensate from the main body 1.
