[0018] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0019] like Figure 1-3As shown, in the embodiment, a carton with good heat preservation effect is provided, including an outer box 1, a heat preservation liner 2, a support frame 3, a connecting rod 4 and a box cover 5. A slide groove 11 is vertically arranged inside the outer box 1, and the support frame 3 is arranged at the four corners inside the outer box 1, and the support frame 3 is slidably connected with the slide groove 11. Two adjacent support frames 3 are connected by connecting rods 4. A heat preservation liner 2 is also arranged between two adjacent support frames 3. The two ends of the heat preservation liner 2 are respectively plugged with the card slots 31 on the side of one of the support frames 3. A box cover 5 is arranged on the top of the outer box 1, and an ice storage cavity 51 is arranged on the box cover 5. The top of the support frame 3 extends into the ice storage cavity 51. A vent hole 32 is arranged in the support frame 3, and a waterproof breathable membrane 33 is arranged in the vent hole 32. The ice storage cavity 51 is connected with the outer box 1 through the vent hole 32. In this embodiment, the outer box 1 is a rectangular box body, and the box cover 5 arranged on the top can close the outer box 1 to form a sealing structure. Since cartons are usually stacked, the support frame 3 can provide vertical support force to prevent the cartons below from being crushed, and the connecting rod 4 can provide lateral support for the support frame 3 to prevent the support frame 3 from tipping over and causing support failure. The support frame 3 can be pulled out from the slide slot 11, and the thermal insulation liner 2 can also be separated from the card slot 31, so that they can be disassembled and replaced separately when the outer box 1 or the thermal insulation liner 2 is damaged, without scrapping the entire carton, thereby achieving the purpose of cost saving. The ice storage chamber 51 is filled with ice cubes, and the cold air in the ice storage chamber 51 can enter the outer box 1 through the vent hole 32, so as to cool down the goods and improve the insulation effect. When the ice cubes are completely melted, it is only necessary to add ice cubes into the ice storage chamber 51 again without opening the box cover 5, which is easy to operate. The waterproof and breathable membrane 33 can prevent water vapor from entering the outer box 1, causing the goods to be soaked, and the height of the top surface of the supporting frame 3 should be higher than the bottom surface height of the ice storage chamber 51 to prevent the melted water from blocking the vent hole 32.

[0020] Specifically, the outer box 1 includes a reinforcing layer 12, a metal mesh 13 and an outer protective layer 14 arranged in sequence from the inside to the outside, and the slide 11 is located on the reinforcing layer 12. In this embodiment, the reinforcing layer 12 is made of glass fiber material, which can increase the bearing strength of the outer box 1. The provided metal mesh 13 can prevent the outer box 1 from being punctured. The outer protective layer 14 is made of kraft paper material, which can not only play a waterproof role to prevent the carton from softening, but also play an anti-scratch effect to keep the surface of the carton beautiful.

[0021] Specifically, the thermal insulation liner 2 includes a waterproof layer 21, a buffer layer 22 and a thermal insulation layer 23 arranged in sequence from the inside to the outside. In this embodiment, the waterproof layer 21 can prevent the thermal insulation layer 23 from being soaked. The buffer layer 22 can cushion the goods inside when the carton is bumpy to reduce the impact of vibration. The thermal insulation layer 23 can isolate the influence of the external environment temperature to play a role of heat preservation.

[0022] Specifically, a support pad 6 is provided at the bottom of the outer box 1. In this embodiment, the support pad 6 can suspend the outer box 1 in the air, and can prevent the bottom of the carton from being stained with water on the ground.

[0023] Specifically, anti-skid patterns are provided on the support pad 6. In this embodiment, the anti-skid patterns can increase the friction with the ground to prevent the carton from accidentally sliding.

[0024] Specifically, handles 7 are provided on both sides of the outer box 1. In this embodiment, the provided handles 7 facilitate users to lift and carry the carton.

[0025] Working principle:

[0026] When in use, the arrangement of the supporting frame 3 and the connecting rod 4 can make the carton more stable during use, effectively prevent the carton from being squeezed and deformed when stacked, thereby protecting the items inside the carton, and because the outer box 1, the thermal insulation liner 2 and the supporting frame 3 are detachably connected, they can be disassembled and replaced separately when the outer box 1 or the thermal insulation liner 2 is damaged, without scrapping the entire carton, thereby achieving the purpose of cost saving; the arrangement of the thermal insulation liner 2 can isolate the influence of the external ambient temperature to play a role in heat preservation, and the ice storage cavity 51 can be filled with ice cubes to cool the inside of the outer box 1, and it is convenient to replace the ice cubes after they melt.
