Abstract

The invention discloses a test tube placement rack for a chemical laboratory, which includes a base, a fixed shell is fixedly connected to both sides of the top of the base, and a positioning plate is fixedly connected to the outer side of the fixed shell, and the positioning plate is far away from the fixed shell One side of the fixed housing is provided with a card slot, and the inner cavity of the fixed shell is provided with a limit block, and the top of the limit block is fixedly connected with a lifting rod, and the top of the lifting rod penetrates to the outside of the fixed shell. The present invention is provided with a base, a fixed shell, a positioning plate, a card slot, a block, a pull rod, a lifting rod, a housing, a second fixed plate, a through hole, a first fixed plate, a limiting block, a limiting plate, a sliding rod and The combined use of the spring solves the problem that the height of the existing test tube rack cannot be adjusted. The test tube rack used in the chemical laboratory has the advantage of being able to adjust the height according to the height of the test tube, which is convenient for the user and improves the current situation. The practicability of the test tube rack is worth promoting.

Description

technical field [0001] The invention relates to the technical field of chemical experiment teaching aids, in particular to a test tube placement rack for chemical laboratories. Background technique [0002] Chemistry is a kind of natural science. It studies the composition, properties, structure and change laws of substances at the molecular and atomic levels, and creates new substances. The world is composed of substances, and chemistry is the main method for human beings to understand and transform the material world. One of the methods and means, it is a subject with a long history and full of vitality. Its achievements are an important symbol of social civilization. There are two forms of chemical change and physical change in chemistry. [0003] Chemical experiment tools also include test tubes. When storing test tubes, test tube racks are required. The existing test tube racks are fixed and cannot adjust the height of the test tube racks. Due to the different heights o...
