Description

Technical Field

[0001] This utility model belongs to the technical field of air-cooled freezers and relates to the structure of an air-cooled low-temperature freezer. Background Technology

[0002] Air-cooled low-temperature freezers are high-efficiency low-temperature refrigeration and freezing equipment designed for deep freezing. They are typically used for rapid cooling of food and beverages to preserve nutrients and maintain freshness. Currently, most air-cooled low-temperature freezers use a cooling unit at the top of the cabinet to generate cold air, which is then blown into the interior by a fan for rapid freezing. However, when the freezer is full, food can clog the air vents, preventing cold air from flowing from the top to the bottom. This uneven distribution of cold air negatively impacts preservation. Furthermore, traditional freezers have fixed partitions for categorized freezing, but in practice, the quantity and size of items vary, and the fixed partitions prevent flexible adjustment of storage space, reducing the freezer's versatility. While existing freezers are equipped with casters for easy movement, they are not ideal for securing the freezer in place.

[0003] When using the above technology, the following technical problems were found in the existing technology: When the freezer is full, the cold air vent is blocked, which prevents the cold air from being delivered from the top to the bottom of the cabinet, resulting in uneven distribution of cold air inside the freezer. It is impossible to flexibly adjust the storage space according to the storage situation, which reduces the applicability of the freezer's internal space. Existing freezers are all equipped with casters at the bottom, which are convenient for moving, but not convenient for fixing the freezer. Utility Model Content

[0004] The technical problem this invention aims to solve is that when the freezer is fully loaded, the cold air vents are blocked, resulting in uneven distribution of cold air inside the freezer. This makes it impossible to flexibly adjust the storage space according to the storage conditions, reducing the applicability of the freezer's internal space. Furthermore, the casters make it difficult to secure the freezer.

[0035] During operation, the freezer body 1 can be easily moved using the casters 12. Once the position of the freezer body 1 is determined, the support block 15 and anti-slip pad 16 are moved by rotating the threaded sleeve 14. When the support block 15 and the anti-slip pad 16 come into contact with the ground, they can support the freezer. The rubber anti-slip pad 16 can prevent the freezer from sliding due to the casters 12. Then, the movable plate 9 slides along the slide groove 801. After determining the position of the movable plate 9, it is fixed by the cooperation of the hand screw 10 and the protrusion 901. Then, the spacing of the shelf 11 is adjusted, and then the shelf 11 slides into the support plate 902. The shelf 11 is limited by the cooperation of the limiting plate 1103 and the limiting hole, preventing the shelf 11 from being stopped. The sliding mechanism adapts to the storage of items of different sizes, improving the usability of the freezer's internal space.
