Experiment trolley for classroom teaching of analytical chemistry

Abstract

The invention discloses an experiment trolley for classroom teaching of analytical chemistry. The experiment trolley comprises a bottom plate, wherein the bottom plate is of a hollow cuboidal structure, an opening is formed in the bottom end of the bottom plate, two electric telescopic columns which are arranged symmetrically are connected to the middle position of the top end of the bottom plate,top ends of the electric telescopic columns are connected with guiding rods, second springs sleeve the guiding rods, two fixing blocks which are arranged symmetrically are arranged at the two sides of the top end of the bottom plate, the electric telescopic columns are arranged between the two fixing blocks, a cross rod is connected to each of the sides, close to each other, of the two fixing blocks, a first spring sleeves each cross rod, one end of each first spring is connected with the corresponding fixing block, and a traveling block is connected with one end, far away from the corresponding fixing block, of each first spring. According to the experiment trolley for classroom teaching of analytical chemistry, the experiment trolley for classroom teaching of analytical chemistry and chemical apparatuses on the experiment trolley can be effectively subjected to multi-directional buffering protection, and the chemical apparatuses on the experiment trolley are prevented from being damaged; and meanwhile, the operating altitude of the experiment trolley can be adjusted, and the structure is novel, so that the experiment trolley is suitable for being popularized.

Description

technical field [0001] The invention relates to the technical field of experimental teaching equipment, in particular to an analytical chemistry classroom teaching experimental vehicle. Background technique [0002] Analytical chemistry is a science concerned with the analysis methods and theories of chemical information such as the composition, content, structure and form of substances, and is an important branch of chemistry. It is to identify which components are contained in the substance, and what components the substance is composed of, to determine the relative content of various components, and to study the molecular structure or crystal of the substance. The entry introduces the development history, analytical methods, application fields, error elimination, etc. of analytical chemistry. [0003] When teachers teach analytical chemistry experiments to students, they will use teaching experiment vehicles. Various chemical experiment instruments made of glass products...

Problems solved by technology

[0003] When teachers teach analytical chemistry experiments to students, they will use teaching experiment vehicles. Various chemical experiment instruments made of glass products will be placed on the experiment vehicles. However, when ordinary chemical experiment vehicles are used, they may not Be careful to collide with the experimental cart, or when pushing the chemical experimental cart, the glass instrument on the experimental cart may be broken due to the bumping of the experimental cart. Therefore, in order to solve such problems, we propose an analytical chemistry classroom teaching experimental cart
