Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a circular spiral closure robot storage device. Background Technology

[0002] In the biomedical field, biological samples need to be stored in a low-temperature environment for long-term preservation, and low-temperature storage refrigerators are commonly used for storage and management.

[0003] However, when biological samples need to be moved in or out of the refrigerator, opening the refrigerator causes the low-temperature environment inside the refrigerator to undergo hot and cold gas convection with the normal temperature environment outside, which raises the temperature inside the refrigerator. This poses a safety hazard to the biological samples stored inside the refrigerator and also requires more energy to cool them down again.

[0004] Therefore, there is an urgent need in the existing technology for a circular spiral closed robotic storage device to solve the problems of safety hazards and energy loss caused by hot and cold gas convection during sample storage. Utility Model Content

[0029] As preferred, the lifting guide rail is arranged in the rotating cylinder in parallel with the lifting lead screw and is in sliding connection with the lifting slider.

[0063] In the biomedical field, biological samples need to be stored in a low-temperature environment for long-term preservation, and low-temperature storage refrigerators are commonly used for storage and management.

[0064] However, when biological samples need to be moved in or out of the refrigerator, opening the refrigerator causes the low-temperature environment inside the refrigerator to undergo hot and cold gas convection with the normal temperature environment outside, which raises the temperature inside the refrigerator. This poses a safety hazard to the biological samples stored inside the refrigerator and also requires more energy to cool them down again.

[0065] Therefore, there is an urgent need in the existing technology for a circular spiral closed robotic storage device to solve the problems of safety hazards and energy loss caused by hot and cold gas convection during sample storage.

Through the rotation and alignment of the rotating cylinder 2, the internal and external environments of the frame door 11 are isolated during the sample transfer process, reducing the convection and conduction of hot and cold gas environments and saving energy. At the same time, when the transfer door 24 aligns with the frame door 11, the cold air inside the frame door 11 enters the rotating cylinder 2, keeping the rotating cylinder 2 in a low-temperature field and ensuring that the sample is protected from low temperature during the rotation and transport process.
