[0023] Specifically, in order to prevent local heat conduction caused by the characteristics of the structure or material, the spring sheet 8 and the clamp head 9 on the vacuum insulation layer main body 4 are pressed into the clamp plate 7 through the mutual cooperation of the clamp plate 7, the spring sheet 8, the clamp head 9 and the fixed block 10. Under the action of the spring sheet 8, the clamp head 9 can be bent toward the inside of the clamp plate 7. When the clamp head 9 reaches the bottom of the clamp plate 7, the clamp head 9 can be clamped to the clamp plate 7, and then the cold bridge main body 2 can be fixed to the connection between the vacuum insulation layer main body 4 and the vacuum insulation layer main body 4. Under the action of the cold bridge main body 2, the cold bridge phenomenon around the vacuum insulation layer main body 4 can be reduced, thereby enhancing the overall thermal insulation effect and improving the thermal insulation performance.

[0024] Reference Figure 1-Figure 3 The sealing assembly 6 includes a sealing layer 1 601, a sealing layer 2 602 is provided on the top of the sealing layer 1 601, a sealing layer 3 603 is provided on the top of the sealing layer 2 602, and a sealing layer 4 604 is provided on the top of the sealing layer 3 603. The sealing layer 1 601 is prepared by polyurethane foam as a raw material, the sealing layer 2 602 is prepared by aerogel as a raw material, the sealing layer 3 603 is prepared by polystyrene foam as a raw material, and the sealing layer 4 604 is prepared by aluminum foil as a raw material. The middle part of the top of the bottom lining plate 1 is fixedly connected to the cold bridge body 2, and the cold bridge body 2 is fixedly connected to the adjacent end of the fixed block 10;

[0025] Specifically, through the mutual cooperation of sealing layer one 601, sealing layer two 602, sealing layer three 603, and sealing layer four 604, sealing layer one 601 has low thermal conductivity and high strength, sealing layer two 602 is one of the lightest solid materials known to date, with extremely low thermal conductivity and nano-scale pore structure, making it difficult for gas molecules to penetrate, and has very good sealing and thermal insulation properties, sealing layer three 603 has a light weight and good thermal insulation properties, and its closed-cell structure also provides a certain degree of sealing, sealing layer four 604 can prevent moisture from entering, while maintaining a certain degree of air permeability, and at the same time improve the overall sealing of the thermal insulation material, and the mutual cooperation between them can increase the sealing of the vacuum insulation structure, thereby preventing air, moisture or other gases from entering the vacuum insulation layer, thereby maintaining a vacuum state, and thus ensuring the long-term stability of its thermal insulation performance.

[0026] Working principle: Through the mutual cooperation of the card plate 7, the spring sheet 8, the card head 9 and the fixing block 10, the cold bridge body 2 and the vacuum insulation layer body 4 are fixed, and the spring sheet 8 and the card head 9 on the vacuum insulation layer body 4 are pressed into the card plate 7. Under the action of the spring sheet 8, the card head 9 can be bent toward the inside of the card plate 7. When the card head 9 reaches the bottom of the card plate 7, the card head 9 can be engaged with the card plate 7, and then the cold bridge body 2 can be fixed to the connection between the vacuum insulation layer body 4 and the vacuum insulation layer body 4. Under the action of the cold bridge main body 2, the cold bridge phenomenon around the vacuum insulation layer main body 4 can be reduced. Then, sponge 1 3 and sponge 2 5 are installed on the vacuum insulation layer main body 4, and then the bottom lining plate 1 and sponge 1 3 are assembled. Then, the sealing component 6 is installed on sponge 2 5. In this way, the insulation structure not only reduces the cold bridge phenomenon around it, but also prevents air, moisture or other gases from entering the interior of the vacuum insulation layer, thereby maintaining a vacuum state, which not only enhances the overall thermal insulation effect, but also ensures the long-term stability of its thermal insulation performance.
