Abstract
Description
Technical Field
[0001] This utility model belongs to the field of laboratory equipment and relates to a foldable centrifuge tube. Background Technology
[0002] Centrifuge tubes are widely used in laboratories for sample storage and centrifugation, but traditional centrifuge tubes are mostly fixed in shape and large in size, which makes transportation, storage and cleaning inconvenient. As laboratory equipment develops towards high throughput and portability, how to achieve the folding function of the tube body while ensuring the stability and sealing of centrifugation operation has become an urgent technical problem to be solved. Summary of the Invention
[0003] The advantage of this utility model is that it can provide a foldable centrifuge tube, which, by adopting a multi-segment hinge structure, a special locking mechanism and a double sealing design, can be unfolded into a straight cylinder when in use and folded into a small volume when not in use, thereby facilitating transportation, storage and cleaning.
[0004] To achieve the above objectives, this utility model relates to a foldable centrifuge tube, comprising three parts: a top cover 1, a middle folding body 2, and a base 3.
[0005] The top cover and base are designed with anti-slip and impact-resistant structures. The top cover and base are equipped with sealing gaskets: top cover sealing gasket 11 and base sealing gasket 31. The middle folding body is a plastic telescopic tube with three flexible and bendable connecting parts: upper flexible and bendable connecting part 21, middle flexible and bendable connecting part 22, and lower flexible and bendable connecting part 23. When unfolded, it forms a continuous straight cylindrical tube, and when folded, the overall volume is significantly reduced.
[0006] Beneficial effects: This utility model relates to a foldable centrifuge tube, which can significantly reduce its volume when not in use without affecting centrifugation separation effect and sealing performance, facilitating storage, transportation and cleaning. The multi-segment hinge structure and locking mechanism adopted ensure stability and safety during use, making it suitable for high-requirement laboratory environments in fields such as biology and chemistry, and has significant technological advancements and practical application value.

[0013] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0014] Example 1
[0015] This utility model centrifuge tube consists of a top cover 1, a middle folding body 2, and a base 3. When unfolded, the middle folding body 2 forms a continuous straight cylindrical centrifuge tube with a smooth inner cavity, which facilitates uniform sample distribution. When folded, the middle folding body 2 folds in a predetermined direction, significantly reducing the overall volume and facilitating storage and transportation. Both the top cover 1 and the base 3 are designed with anti-slip and impact-resistant structures, and are equipped with internal sealing gaskets to further enhance overall sealing and safety.
[0016] The above embodiments are for illustrative purposes only and are not intended to limit the scope of the present utility model patent. It should be noted that various changes and modifications can be made by those skilled in the art without departing from the concept of the present utility model, and these all fall within the protection scope of the present utility model. Therefore, all equivalent changes and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
