Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a test tube support device. Background Technology

[0002] Test tubes are one of the most commonly used experimental instruments in biological and chemical experiments. In actual use, test tube racks and other support devices are needed to stably support the test tubes so that they can be placed stably on the table for use or preparation.

[0003] A search revealed that Chinese Patent CN202321554572.5 discloses a test tube support device with a protective support mechanism. The protective support part of the protective support mechanism can limit the top of the test tube when the test tube rack assembly moves, preventing the test tube from falling and being damaged due to detachment from the test tube rack assembly during movement. In use, the protective support part can support the test tube rack assembly, improving the stability of the test tube rack assembly placed on the table. Furthermore, when the protective support part supports the test tube rack assembly, the height of the test tube rack assembly can be adjusted, thus facilitating operation by staff and making it convenient to use.

[0004] The above-mentioned technical solution has the following defects. Although such a test tube support device can limit the test tube through the top protective component to prevent the test tube from falling off the support device and causing damage during actual use, it is inconvenient to pick up the test tube during actual use. In order to facilitate the use of test tubes and to stably position test tubes of various models, a test tube support device is proposed. The device is designed with a circular structure and a suction cup at the bottom, which can be stably placed on the table. It is equipped with a rotatable test tube holder to make it easy to pick up and put down the test tubes. The test tube holder is equipped with a positioning silicone clamp and a positioning silicone cylinder to stably clamp and position the test tubes and prevent them from falling off and being damaged.

[0005] In view of this, this work improves and solves the above problems. Through dedicated research and application of theoretical principles, a technical solution with a reasonable design that can effectively improve the above defects has finally been proposed.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.
