Description

Technical Field

[0001] The utility model relates to the technical field of multi-tube vortex mixers, and more specifically, to a pressing device for a multi-tube vortex mixer. Background Art

[0002] The multi-tube vortex mixer can simultaneously mix the liquids in multiple test tubes of different specifications. In the fields of chemical, biological, and medical research, etc., during the experimental process, it is often necessary to mix the liquids in multiple test tubes of different specifications. The multi-tube vortex mixer uses the principle of vortex motion. The test tube rack is driven by a high-speed rotating motor, so that the liquid in the test tube generates a swirling flow; this flow can quickly and fully mix the liquid in the test tube. Whether it is a single-specification test tube or a combination of test tubes of different specifications, a uniform mixing effect can be achieved. After placing the test tube on the test tube rack, it is necessary to squeeze and limit the top of the test tube.

[0003] After retrieval, the utility model patent with the publication number of CN219399961U discloses a pressing device applicable to a multi-tube vortex mixer, which includes a long support column with threads on its outer surface, a threaded sleeve sleeved on the long support column, a handle located on the side of the threaded sleeve, a first threaded channel located in the vertical inner diameter of the threaded sleeve, a short support column with threads on its outer surface, and a pressing plate for pressing and fixing the top of the test tube; for the pressing device applicable to the multi-tube vortex mixer, after mixing is completed, only need to lift the pressing plate to the top of the long support column and separate it from the short support column, then the mixed test tube can be rotated around the long support column to be taken out and a new test tube can be put in, instead of completely removing the pressing plate after each mixing. The threaded sleeve has both the functions of horizontal locking and vertical movement, avoiding damage to the test tube caused by over-pressing the pressing plate downward due to the need to fix the threaded sleeve. During the mixing process, the wear of the pressing device will be concentrated on the wear-resistant sleeve, and the mixing operation can be continuously carried out by replacing the wear-resistant sleeve.

[0004] However, the above patent still has the following deficiencies: it is necessary to manually lift and lower the pressing plate for extrusion, and the usability is poor. At the same time, the mixed test tubes are directly exposed outside, which is not convenient for protecting the test tubes with swirling motion. For this reason, we propose a pressing device for a multi-tube vortex mixer. Content of the Utility Model
