Problems solved by technology

[0002] In chemical laboratories, there are many kinds of containers that need to be cleaned, such as test tubes, measuring cylinders, etc. At present, most of them use straight rod type test tube brushes or test tube cleaning machines; and test tube cleaning machines are large in size, high in cost, and complicated to operate; straight rod type During operation, it is difficult to clean the remaining chemicals inside the test tube. The current test tube brush can only correspond to a single test tube, which causes inconvenience during use. Moreover, the current test tube brush can only be discarded after the bristles are damaged. , causing damage to the environment

Abstract

The invention belongs to the technical field of cleaning experimental instruments, in particular to a test tube brush for high school chemistry experiment. The test tube brush is characterized in thata rotating lever passes through the handheld lever and a telescopic sleeve rod in turn, and the lower end of the rotating rod is connected with the inner side of the hemispherical structure brush head by a first rolling bearing. A plurality of gears are arranged on the rotating rod. One side of the gear is connected with a first worm, the other side of the gear is connected with a second worm, the first worm is parallel to the second worm, one end of the first worm is connected with a positive screw sleeve, the other end of the first worm is connected with a reverse screw sleeve, the positivescrew sleeve is threaded with a positive screw rod, and the reverse screw sleeve is threaded with a reverse screw rod. The invention has the characteristics of simple structure, low cost and convenient use, and can be applied to washing test tubes of various types, and the washing is more uniform and thorough, and does not damage the wall of the test tubes.
