Description

Technical Field

[0001] The utility model relates to the technical field of freezing devices, in particular to a biological sample freezing device. Background Art

[0002] Biological sample freezing boxes are an indispensable and important tool in biological sample storage. They are specially designed to safely and effectively preserve biological samples in a low-temperature environment. The freezing boxes can maintain the samples in a stable low-temperature state for a long time, reducing the impact of temperature fluctuations on the samples, thereby maintaining the activity and stability of the samples.

[0003] When using a cryopreservation box to preserve biological samples, the biological samples are not placed directly in the cavity of the cryopreservation box. Instead, the biological samples are placed in special cryopreservation tubes, and then the tubes are placed in the cavity. However, different types of cryopreservation tubes have different lengths, while the height inside the cryopreservation box cavity is fixed. This leads to the problem that the cryopreservation box may not fit when the type of test tube changes. If the test tube is too long, the lid cannot be closed, and if it is too short, it is not convenient to take out the test tube, thereby reducing the practicality of the cryopreservation box. Utility Model Content

[0018] The effect achieved by the above components is: by arranging a pin and inserting the pin into the inner wall of the circular hole block, the protective plate and the box body can be auxiliary fixed.

[0019] Preferably, one end of the latch is fixedly connected to a clamping block, the clamping block is made of rubber, and the vertical cross-section of the clamping block is an isosceles trapezoid.

[0020] The effect achieved by the above components is: by setting a card block, the card block is inserted into the inner wall of the circular hole block. One end of the card block is smaller, which is convenient for insertion. At the same time, the other end of the card block is larger, which can limit the position between the circular hole block and the pin, thereby preventing the pin from detaching from the inner wall of the circular hole block.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are:

[0022] In the present invention, a plurality of inserts and a bottom plate are provided. Under the action of the threaded rod, the threaded rod drives the inserts connected to the bottom plate to slide on the inner wall of the cavity during the extension and contraction process, thereby facilitating the adjustment of the length of the cavity according to the length of the frozen test tube, so that the freezing box can be adapted to a variety of test tubes, thereby improving the practicality of the freezing box.
