Description

Technical Field

[0001] The utility model relates to the technical field of storage boxes, in particular to a freezing storage box with an antibacterial coating. Background Art

[0002] A freezing storage box refers to a specific device that can maintain items at extremely low temperatures and is usually used to store temperature-sensitive biological samples, drugs, chemicals, etc. Its precise temperature control, good heat preservation effect, durability and other characteristics make it an ideal choice for storing temperature-sensitive items.

[0003] For an existing freezing storage box, such as a freezing storage box with low-temperature regulation disclosed in the utility model patent with the application number 202222737890.7, its main structure includes that the side wall of the box body is rotatably connected with a box cover through a rotating shaft, a refrigerator is fixedly installed on the inner side wall of the box body, an alarm is embedded and installed in the inner cavity of the box cover, a temperature transmitter is fixedly installed on the inner side wall of the box body, the inner side wall of the box body is fixedly installed with a first clamping plate through a support column in a uniformly symmetric manner, movable plates are arranged in the inner cavity of the box body in a uniformly symmetric manner, and a plurality of second clamping plates are fixedly installed on the side wall of the movable plate through connecting blocks in a uniformly manner; during use, samples are sequentially placed between each first clamping plate and the second clamping plate, and then the threaded rod is rotated, so that the threaded rod drives the top block to fit and rotate on the surface of the adjacent movable plate. As the threaded rod rotates, the movable plate is pushed to move through the rotating top block, so that the movable plate drives another movable plate to move through a plurality of connecting rods, so that each movable plate drives the second clamping plate to move through the connecting block on the surface at the same time, so that a plurality of second clamping plates move towards the corresponding first clamping plates at the same time, so that the containers for storing samples are fixed between the first clamping plate and the second clamping plate, and thus the containers for holding a plurality of samples are sequentially fixed inside the box body.

[0004] However, when most of the existing storage boxes are opened, the samples are all exposed outside, which not only easily causes the samples to be contaminated by the outside, but also causes the cold air in the storage box to escape, increasing the energy consumption of the device. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides a freezing storage box with an antibacterial coating, which not only reduces the loss of cold air when the box is opened, saves energy consumption, but also reduces the air flow exchange between the outside and the inside of the box when the box is opened, ensuring the cleanliness inside the box.
