[0027] Specifically: The outer box 1 has symmetrical lifting holes 4 on its side. Inside the lifting holes 4, there are corresponding fixed connections with soft pads 6 to avoid hand injuries and improve handling comfort.

[0028] Specifically: multiple limiting plates 7 are fixedly connected inside the outer casing 1, and multiple limiting slide plates 8 are fixedly connected to the side of the fixing plate 9.

[0029] Specifically: the limiting slide plate 8 is movably connected to the limiting plate 7, the lower end of the fixing plate 9 is fixedly connected to the reinforcing bracket 10, and multiple ventilation channels 19 are opened on the side of the limiting slide plate 8 to improve heat dissipation efficiency and enhance the refrigeration effect.

[0030] Specifically: the inner side of the outer box 1 is fixedly connected with multiple fixed sliding grooves 12, and the side of the inner box 11 is fixedly connected with multiple fixed sliding pieces 13, with the fixed sliding grooves 12 movably connected to the fixed sliding pieces 13.

[0031] Specifically: A fixing plate 2 is fixedly connected to the side of the outer box 1. The fixing plate 2 and the outer box 1 are provided with multiple fixing holes 16. A fixing ring 17 is movably connected in the fixing hole 16 to prevent the carton from collapsing.

[0032] Specifically: a first top cover 3 is fixedly connected to the upper end of the outer box 1, a second top cover 18 is fixedly connected to the upper end of the outer box 1, a first adhesive plate 20 is fixedly connected to the lower end of the first top cover 3, a second adhesive plate 21 is fixedly connected to the lower end of the second top cover 18, and the first adhesive plate 20 is movably connected to the second adhesive plate 21 to facilitate the storage and retrieval of goods.

[0033] Specifically: multiple heat insulation plates 14 are fixedly connected to the inside of the inner box 11, and multiple heat dissipation holes 15 are opened on the side of the inner box 11 to avoid local temperature abnormalities and ensure the quality of refrigerated items.

[0034] Working principle:

[0035] The symmetrically arranged lifting holes 4 on the side of the outer box 1 play a crucial role. The soft pads 6 fixed inside the lifting holes 4 are made of soft sponge material covered with wear-resistant leather, conforming to the human hand's gripping habits. When handlers lift the box, the soft pads 6 effectively distribute pressure, preventing direct contact between the hands and the hard edges of the lifting holes 4, reducing the risk of injury, improving handling comfort, ensuring smooth handling, and laying the foundation for subsequent use. During assembly, the fixing grooves 12 on the inside of the outer box 1 and the fixing tabs 13 on the side of the inner box 11 fit tightly together. The fixing grooves 12 are made of wear-resistant engineering plastic and are vertically arranged on the inside of the outer box 1; the fixing tabs 13 are made of aluminum alloy, providing good rigidity and toughness. When installing the inner box 11, the fixing tabs 13 precisely embed into the fixing grooves 12, smoothly sliding to the designated position, ensuring the relative position of the inner box 11 and the outer box 1 is stable, providing a stable structure for subsequent heat insulation and storage. Simultaneously, the fixing plate 9 inside the outer box 1 is connected to the limiting plate 7 via the limiting slide plate 8. The limiting plate 7 is made of waterproof wood and is fixed inside the outer box 1; the limiting slide plate 8 is made of polytetrafluoroethylene (PTFE) with excellent self-lubricating properties. Operators can flexibly adjust the position of the fixing plate 9 according to the size and shape of the refrigerated items to meet different storage needs. The triangular stainless steel reinforcing bracket 10 at the lower end of the fixing plate 9 enhances its load-bearing capacity and prevents deformation when heavy objects are placed on it. During use, the heat insulation plate 14 on the inner side of the inner box 11 and the heat dissipation holes 15 on the side work together to maintain a stable internal temperature. The heat insulation plate 14 is made of polyurethane foam, with tiny closed air bubbles forming a highly efficient heat insulation barrier to prevent external heat from entering. When the refrigeration equipment is running, the items inside the inner box 11 breathe or the equipment generates heat; the hot air rises and is discharged through the heat dissipation holes 15, while cold air from the outside enters from below, forming a heat exchange cycle to avoid localized temperature anomalies and ensure the quality of the refrigerated items. The ventilation ducts 19 on the side of the limiting slide plate 8 promote air circulation inside the outer box 1, assisting in heat dissipation and further improving the refrigeration effect. When the carton is closed, the first adhesive plate 20 at the lower end of the first top cover 3 and the second adhesive plate 21 at the lower end of the second top cover 18 are tightly bonded together. Both are made of biodegradable paper material and coated with environmentally friendly water-based adhesive. After bonding, they form a good seal, preventing external heat intrusion and internal cold air leakage, maintaining a low-temperature environment. When opening, the adhesive parts are gently peeled off, making the operation simple and without damaging the carton structure, facilitating the storage and retrieval of goods. The fixing plate 2 on the side of the outer carton 1 has fixing holes 16, which connect to the fixing ring 17 made of high-strength spring steel. When stacking cartons, the fixing ring 17 securely connects multiple cartons, preventing them from collapsing due to shaking or external force, ensuring safe storage and transportation. The rubber feet 5 at the lower end of the outer carton 1 are treated with a special formula to prevent slipping and shock absorption, increase friction with the ground, and prevent the cartons from sliding.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
