Test-tube support with shaking function for chemical experiment

Abstract

The invention discloses a test-tube support with a shaking function for a chemical experiment. The test-tube support comprises a mounting seat, wherein a lifting device is fixedly arranged on the right side of the mounting seat; the lifting device comprises a mounting post; a first groove is formed in the upper side of the mounting post; a screw is arranged in the first groove; the lower end of the screw is rotationally connected with the inner bottom of the first groove; a driven bevel gear is fixedly arranged on the screw; the right side of the driven bevel gear is meshed with a driving bevel gear; the driving bevel gear is connected with a rotating rod; the rotating rod penetrates through the mounting post; the outer end of the rotating rod is connected with a handle; a barrel is arranged above the screw; a threaded hole is formed in the lower side of the barrel; the upper part of the screw is in threaded connection with the threaded hole; a sleeve is arranged on the left side of the mounting seat; a guide post is arranged in the sleeve; the top end of the barrel and the top end of a guide post are fixedly connected with a mounting plate together. The test-tube support disclosed by the invention has the advantages of being reasonable in structural design, convenient to lift, excellent in test tube protection effect, excellent in shaking effect and the like, thereby having a certain popularization and application value.

Description

technical field [0001] The invention relates to the technical field of chemical experiments, in particular to a test tube support for chemical experiments with an oscillation function. Background technique [0002] Chemistry is a kind of natural science, which studies the composition, properties, structure and changes of substances at the molecular and atomic levels; it is the science of creating new substances. The world is composed of matter, and chemistry is one of the main methods and means used by human beings to understand and transform the material world. It is a subject with a long history and full of vitality, and its achievements are an important symbol of social civilization. There are two forms of chemical change and physical change in chemistry. [0003] The word "chemistry", if only interpreted literally, is "the science of change". Chemistry, like physics, is a basic science of natural science. Chemistry is a natural science based on experiments. The perio...

Problems solved by technology

In the prior art, the test tube holder is used for storing the test tubes, so the functionality of the test tube holder also needs to be improved; in addition, in the prior art, there are some experiments that need to shake the test tube to improve the reaction effect, If multiple groups of comparative experiments are carried out at the same time, it is impossible to shake multiple groups of test tubes at the same time
