Cleaning device suitable for interiors of test tubes of different sizes

Abstract

The invention relates to the technical field of test tube cleaning, in particular to a cleaning device suitable for interiors of test tubes of different sizes. The invention aims to provide the test tube interior cleaning device which can be used for quickly and thoroughly cleaning test tubes, is high in cleaning efficiency and good in effect and can meet the cleaning requirements of the test tubes with different inner diameters. According to the technical scheme, the cleaning device suitable for the interiors of the test tubes of different sizes comprises a support, a transmission motor, a sector gear, a tooth-missing bevel gear, a rotating shaft and the like; and the transmission motor is fixedly installed on one side face of the support, the sector gear is installed on an output shaft of the transmission motor, the tooth-missing bevel gear and the sector gear are coaxially arranged, and the rotating shaft is installed on the support through a bearing and penetrates through the support. According to the cleaning device, mechanical cleaning of the test tube is achieved, and the problems that due to the fact that the test tube is too long, cleaning is inconvenient and not thoroughwhen the test tube is manually cleaned through a hairbrush are solved; and the cleaning requirements of the interiors of test tubes with different thicknesses can be met, the application range is wide, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of test tube cleaning, in particular to an internal cleaning device suitable for test tubes of different sizes. Background technique [0002] Test tubes are commonly used instruments in chemical laboratories. They are used as reaction containers for small amounts of reagents and are used at room temperature or when heated. Test tubes are divided into ordinary test tubes, support test tubes, centrifuge test tubes and so on. The specifications of ordinary test tubes are represented by outer diameter (mm) × length (mm), such as 15 × 150, 18 × 180, 20 × 200, etc. [0003] After the chemical experiment is done, the test tube must be cleaned to prevent the residue in the test tube from affecting the next chemical experiment. Manually clean the test tube with a brush, because the caliber of the test tube is generally small, so for some long test tubes, it is not convenient to clean it manually, and it is difficul...
