Test tube cleaning device with function on simultaneously cleaning inner side wall and outer side wall

Abstract

A test tube cleaning device with the function of simultaneously cleaning the inner and outer walls, comprising a lower support plate, a height adjustment device is fixedly connected to both sides of the support plate, an upper support plate is fixedly connected to the top of the height adjustment device, and an upper support plate is provided in the middle of the upper support plate A through hole, an annular rubber gasket is fixedly connected to the side wall of the through hole, a test tube is arranged in the annular rubber gasket, the opening of the test tube is arranged downward, a cleaning column is arranged inside the test tube, and a first bristle is arranged on the outer wall of the cleaning column, and The cleaning column extends downward through the lower support plate, and the lower part of the cleaning column is connected with a driving device, and a cavity is arranged inside the cleaning column. The beneficial effect of the present invention is that the first motor drives the first rotating shaft to rotate, the first rotating shaft drives the driving bevel gear to rotate, and the driving bevel gear drives the driven bevel gear to rotate, so that the driven bevel gear drives the threaded rod to rotate. The adjusting rod moves upwards, thereby realizing the raising of the height of the upper support plate.

Description

technical field [0001] The invention relates to the technical field of test tube cleaning, in particular to a test tube cleaning device with the function of simultaneously cleaning the inner and outer side walls. Background technique [0002] At present, chemistry is an experiment-based discipline, and the formation and development of chemistry are inseparable from experiments. After studying in junior high school, students have a basic understanding of the subject of chemistry. But for high school chemistry learning, some students are still at a loss. When students study, they not only need to master the content in the textbook, but also need to use chemical experiments to form chemical concepts, understand and consolidate chemical knowledge, so chemical experiments are particularly important. [0003] In the process of chemical experiments, test tubes are the most common experimental equipment, and they are used in a large amount. The test tubes used for experiments are ...

Problems solved by technology

[0003] In the process of chemical experiments, test tubes are the most common experimental equipment, and they are used in a large amount. The test tubes used in experiments are cleaned manually, and the cleaning is now basically done with a hair rinse, which is rotated in the test tube. Or it can be done by rinsing back and forth. It is not very convenient to clean, and it is easy to cause the test tube to break when cleaning, which will hurt students or teachers, and the large amount of use will lead to a long cleaning time; Contaminants may remain
