Description

Technical Field

[0001] The utility model relates to the technical field of sample preservation, in particular to a quick access device for a liquid nitrogen tank freezing box. Background Art

[0002] Liquid nitrogen cryostat is a container used to store biological samples at low temperatures. It is usually made of polymer materials or metals and has excellent thermal insulation properties, which can prevent the heat from the liquid nitrogen from entering, thus maintaining a low temperature environment.

[0003] Currently, the storage and retrieval operations of cryogenic tanks used to store cryogenic tubes in laboratories and sample libraries are mainly performed manually. During the operation, operators with relevant qualifications must wear low-temperature protective gloves, especially when operating liquid nitrogen tanks. The storage and retrieval locations must be manually searched, which is time-consuming. There are also risks of human error and rewarming of cryogenic tubes, which leads to a reduced sample revival rate and even sample scrapping, resulting in irreparable losses. Utility Model Content

[0009] As a further improvement of the above solution, the outer surface of the movable door screw is threadedly connected to the movable door body, and one side of the installation frame is fixedly connected to a lifting motor.

[0010] Through the above technical solution, the movable door body is driven by the lifting motor, and can be adaptively adjusted according to the freezing boxes of different sizes and heights, ensuring that the freezing boxes can be safely and securely stored in the appropriate position. The movable door body rotates along the outer surface thread of the movable door screw, and can achieve flexible up and down movement, which is convenient for storing and accessing freezing boxes at different levels, thereby improving operational flexibility.

[0011] As a further improvement of the above solution, the output end of the jacking motor is fixedly connected to a jacking transmission belt, and a jacking positioning plate is provided at the top end of the jacking transmission belt.

[0012] Through the above technical solution, the lifting motor drives the lifting positioning plate through the lifting transmission belt, which can achieve smooth and continuous vertical movement, ensuring the stability of the cryobox during the lifting process.

The design of the conveyor belt allows the cryo boxes to be arranged in an orderly manner on the transfer base, facilitating batch operations and improving sample management efficiency.

[0015] As a further improvement of the above solution, an auxiliary plate is fixedly connected to the surface of the transfer base plate, and a transfer motor is fixedly connected to the surface of the auxiliary plate.

[0016] Through the above technical solution, the addition of the auxiliary plate can enhance the installation stability of the transfer motor and ensure that the motor does not cause unnecessary displacement or vibration during operation.

[0017] As a further improvement of the above solution, the output end of the transfer motor is fixedly connected to a transfer transmission belt, the bottom end of the transfer transmission belt is fixedly connected to a transfer screw, and the outer surface of the transfer screw is provided with a movable slider.
