Test tube cleaning device used for chemical experiments

Abstract

The invention discloses a test tube cleaning device used for chemical experiments. The test tube cleaning device comprises a box body. A cover plate is arranged at the upper end of the box body. Firstsliding grooves are formed in the two sides of the inner wall of the box body, and first sliding blocks are connected in the first sliding grooves in a sliding manner. A partition plate is connectedbetween the first sliding blocks. The two sides of the top end of the partition plate are connected with second electric cylinders. The upper ends of the second electric cylinders are fixedly connected to the cover plate. A motor is installed at the upper end of the partition plate. By means of the test tube cleaning device used for the chemical experiments, due to the arrangement of first electric cylinders, a fixing plate and the cover plate can be separated, then a cleaning groove is placed in the box body, a tray driven by the first sliding blocks is put into the cleaning groove in a sliding manner, then test tubes are put into test tube grooves in the tray, and therefore the test tubes can be better fixed; and due to the arrangement of the second electric cylinders, the first slidingblocks can drive the partition plate to slide in the box body, and therefore rotating rods and sponge bars at the lower portion of the partition plate can be inserted into the test tubes, and the testtube cleaning device is suitable for cleaning test tubes at different heights.

Description

technical field [0001] The invention relates to the technical field of chemistry, in particular to a test tube cleaning device for chemical experiments. Background technique [0002] Test tube, a commonly used instrument in chemical laboratories, is used as a reaction container for a small amount of reagents. It is used at room temperature or when heated (it should be preheated before heating, otherwise the test tube is easy to burst). kind. In the chemical experiment teaching course, it is necessary to often use limited test tubes to place different kinds of medicaments, and frequently use test tubes to place different medicaments, and if they cannot be cleaned in time during the process, the teaching experiment results will be affected. In addition, it is difficult for existing cleaning devices to clean test tubes of different lengths, making the cleaning incomplete. Contents of the invention [0003] The object of the present invention is to provide a test tube cleani...
