Description

Technical Field

[0001] The utility model relates to the technical field of chemical teaching, in particular to a test bench for chemical teaching. Background Art

[0002] Chemistry teaching refers to the process of imparting chemical knowledge to students and cultivating their chemical literacy and experimental skills through various teaching methods and means. Its content includes basic chemical knowledge, chemical experiments, chemical calculations and chemical applications, while the methods include classroom lectures, experimental teaching, case teaching and discussion teaching. In the process of experimental teaching, corresponding test benches are often used to facilitate the carrying of experimental teaching aids, experimental equipment, chemicals and other items.

[0003] The utility model with the existing authorization announcement number CN213699969U discloses a chemical test bench with high safety. Through the cooperation of the support table, support legs, threaded rods, adjustment handles, workbenches, lifting rods and telescopic rods, the utility model can freely adjust the height to adapt to the experimenter during use, can fully meet the needs of students of various heights, and is convenient for teaching. Through the cooperation of the support table, support legs, threaded rods, adjustment handles, workbenches, lifting rods and placement table, the reaction mechanism can be kept as far away from the placement table as possible during the reaction to avoid being touched in the laboratory, thereby reducing safety hazards.

[0004] Although the height of the test bench can be adjusted by adopting the above technical scheme, and the distance between the reaction mechanism and the placement table when the reaction occurs can improve safety, the above technical scheme means that experimental tools and chemicals can only be temporarily placed on the table, and there is also a risk of tipping over and falling when stored on the table. There is a lack of a safe storage structure for conveniently storing experimental tools and chemicals, resulting in the safety of the placement and storage of experimental tools and chemicals being relatively general.

[0005] Therefore, those skilled in the art provide a test bench for chemical teaching to solve the problems raised in the above background technology. Utility Model Content

By providing the hollow plate 5, the holes itself can support the reaction vessel during the experiment while moving the debris generated by the reaction to the dirt storage box 4 below, which is convenient for the sorting and collection of experimental residues.

[0025] Two multi-stage electric telescopic rods 204 are fixedly connected to the inner bottom wall of the platform body 1, and the telescopic end of each multi-stage electric telescopic rod 204 is fixedly connected to the bottom surface of the lifting box 203.
