Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model;

Please refer to Figures 1 to 4. In the present utility model, an insulated carton includes a box body 1 and evenly distributed flaps 2. The flaps 2 are connected to the top of the box body 1, and the left and right sides of the box body 1 are bonded. There is an installation box 3. A magnetic plate 4 is fixedly connected to the inner wall of the installation box 3. A heat-insulating film 5 is provided at the bottom of the box 1. The heat-insulating film 5 is attached to the box 1 and penetrates through both sides of the heat-insulating film 5. And extends to the inside of the two installation boxes 3. Both sides of the heat insulation film 5 are fixedly connected with metal strips 6. The metal strips 6 are located inside the installation boxes 3 and are magnetically connected to the magnetic plate 4;

The box 1 includes an external protective layer 101, the installation box 3 is bonded to the external protective layer 101, the inner wall of the external protective layer 101 is fixedly connected with an insulation core board 102, and the inner wall of the insulation core board 102 is fixedly connected with a sponge filling layer 103. The aluminum foil layer 104 is fixedly connected to the inner wall of the sponge filling layer 103, and the tissue layer 105 is fixedly connected to the inner wall of the aluminum foil layer 104.
