Description
Technical Field
[0001] The utility model relates to the technical field of experimental equipment, and more specifically to a test tube support and a rotary shaking table with the same. Background Art
[0002] In the process of preparing chemical or biological drugs, the rotary shaker is a common experimental equipment. It can mix samples and reagents evenly, ensuring that the samples and reagents are fully mixed, and preventing cell tissues from being damaged during the mixing process; in actual use, different specifications of test tubes or centrifuge tubes can be shaken according to needs, with a capacity ranging from 1.5ml to 50ml, and strips and membranes can be mixed and shaken, and can also be used in a suitable low-temperature box or constant temperature incubator.
[0003] However, the clamping devices on the shaker in the prior art are of uniform specifications and cannot meet the requirements of shaking samples of different specifications at the same time. In order to meet the requirements of shaking samples of different capacities, most of them need to be equipped with different shaker plates according to needs, and different shakers need to be replaced many times, which reduces work efficiency. At the same time, the clamping devices in the prior art are mostly open designs, that is, the test tube or centrifuge tube is placed through the open end of the clamping device and fixed with its elastic clamping. However, this design method has the risk of the test tube or centrifuge tube not being firmly fixed, and the sample is prone to falling or leaking, causing losses.
[0004] Therefore, how to provide a bracket and a rotary shaker with a simple structure that can stabilize the test tube and simultaneously meet the needs of shaking samples of multiple specifications is an urgent problem to be solved by technical personnel in this field. Utility Model Content

[0009] An elastic clamp is fixed to the bottom end of the sleeve. The elastic clamp is a U-shaped structure, one end of which is fixed to the inner side wall of the bottom end of the sleeve, and the other end is a free end extending to the outside of the sleeve and toward the direction of the ring.
[0010] Through the above technical scheme, the utility model provides a test tube holder, which can be clamped on the outside of the test tube when the test tube is placed in, through the relative arrangement of the first arc-shaped clamp and the second arc-shaped clamp, thereby effectively preventing the test tube from falling off; at the same time, the first arc-shaped clamp is an elastic clamp, and there is a gap between the first arc-shaped clamp and the second arc-shaped clamp, so that the first arc-shaped clamp can be deformed and clamped according to test tubes of different specifications, thereby meeting the clamping requirements of test tubes of different specifications.
