Then, by rotating the second rotating plate 103, the second rotating plate 103 is made parallel to one side of the upper end of the sealing cover 14. Then, by rotating the positioning bolt 104, the second rotating plate 103 and the sealing cover 14 are fixed on the waterproof outer shell 1 under the action of the positioning bolt 104, making it convenient to pick up and carry the refrigerated package body during use.

[0031] According to Figure 1 , Figure 6 , Figure 7 and Figure 8As shown in the figure, bases 2 are symmetrically arranged on both sides of the bottom of the waterproof housing 1. A first storage bag 25 is provided in the middle of the front of the waterproof housing 1. At the same time, a temperature detector 26 is provided in the middle of the rear side of the waterproof housing 1. Through the temperature detector 26, it is convenient to detect the temperature in real time to prevent the food stored inside from spoiling due to excessive temperature, improving the practicality of use. On the rear side of the waterproof housing 1, second storage bags 27 are symmetrically arranged with respect to the temperature detector 26. The first storage bag 25 includes a heat-insulating and heat-preserving outer cover 2501, a tin sheet 2502, a thin cotton layer 2503, and an aluminum foil layer 2504.

Both ends of the support rods 803 penetrate through a plurality of reinforcing cross bars 802 and extend to the outside of the foam board 801. Both ends of the support rods 803 are inserted and connected to the outer sides of the upper ends of the corresponding reinforcing bottom plates 3 and the outer sides of the lower ends of the fixed top frames 9. At the same time, the outer side of the fixed top frame 9 is attached to the upper end inside the waterproof housing 1. The fixed top frame 9 is a loop structure, and the inner side between the fixed top frames 9 is attached to the outer side of the upper end of the thermal insulation and anti-pollution layer 10. At the same time, the inner side of the upper end of the thermal insulation and anti-pollution layer 10 is attached to the outer side of the heat insulation cotton layer 15. The outside of the cold storage agent frame 12 is sleeved with a film layer, and the inside of the cold storage agent frame 12 is filled with a cold storage agent. At the same time, the cold storage agent is a polymer cold storage agent or a water-based cold storage agent, further improving the internal refrigeration effect when the refrigerated package body is in use.

[0034] According to Figure 1 , Figure 3 and Figure 5 As shown, adjusting and separating components are respectively arranged on both sides inside the thermal insulation and anti-pollution layer 10 for separating and arranging the placed foods, improving the internal refrigeration effect of the refrigerated package body. The adjusting and separating components include slide rails 20, slide seats 21, engaging frames 22, and explosion-proof liquid storage bags 23. Two slide rails 20 are symmetrically arranged. At the same time, a plurality of slide seats 21 are slidably connected to the two slide rails 20. An engaging frame 22 is arranged on the outer side of the slide seat 21. The engaging frames 22 are connected by an explosion-proof liquid storage bag 23. By moving the slide seat 21, it is convenient to adjust the position where the explosion-proof liquid storage bag 23 is placed according to the height of the placed foods, separating and arranging the foods placed inside the same cavity. At the same time, the explosion-proof liquid storage bag 23 is filled with a cold storage agent, and the cold storage agent is composed of a mixture of water and ethanol, so that it maintains heat release for a period of time during use, remains in a snow-melting state when releasing heat, releases heat slowly but has a long maintenance time. A liquid adding and sealing plug 2301 is arranged in the middle of one side of the upper end of the explosion-proof liquid storage bag 23. The outside of the explosion-proof liquid storage bag 23 is sleeved with an absorbent cotton sleeve 24. Through the absorbent cotton sleeve 24, it is convenient to absorb the water stains generated during the use of the explosion-proof liquid storage bag 23, prevent its diffusion and pollution of the internal environment, and at the same time, it also has moisture retention, can ensure temperature stability, extend the heat preservation time, and thus extend the food preservation time.
