Multifunctional chemical experiment support heating device

Abstract

The invention discloses a multifunctional chemical experiment support heating device which comprises a support bottom rack, a vertical rod and fixing parts, wherein the cross section of the support bottom rack is of a frame-shaped structure; openings are formed in two ends of the support bottom rack; holding barrels which extend into the support bottom rack are mounted on two side walls of the middle part of the support bottom rack; the holding barrels are arranged in a manner of tilting downwards to the inner side of the support bottom rack; the holding barrels are provided with sleeve structures arranged inside the openings of the holding barrels on the side walls of the middle part of the support bottom rack; heating openings are formed in the front end and the rear end of the top wall of the support bottom rack; a plurality of support baffle racks are uniformly distributed on the inner sides of the heating openings; heating alcohol lamps are arranged on the bottom plate, right under the heating openings, of the support bottom rack; a plurality of flask fixing devices are arranged at the middle part of the top wall of the support bottom rack; the vertical rod is fixed in the center of the top wall of the support bottom rack; the vertical rod is a spiral shaft column. The multifunctional chemical experiment support heating device is simple in structure, test tubes can be safely stored, the flask holding stability is relatively good, and flasks can be prevented from being toppled over.

Description

technical field [0001] The invention relates to the technical field of chemical experiment teaching, in particular to a multifunctional chemical experiment supporting heating device. Background technique [0002] During chemical experiments, several different types of experimental support devices are required for experimental operations such as heating, filtration, and titration. The existing experimental support devices mainly used in chemical laboratories are composed of iron plates and iron rods, which cannot be disassembled, are heavy and easy to rust, have a large storage space, and are inconvenient to use and move; Placement of laboratory instrument racks, commonly used laboratory instrument racks usually can only store one kind of experimental instrument, and the function is relatively single; various types of equipment need to be prepared when doing experiments, and the operation is troublesome; during the experiment, when the liquid in the beaker is heated, The bea...

The existing experimental support devices mainly used in chemical laboratories are composed of iron plates and iron rods, which cannot be disassembled, are heavy and easy to rust, have a large storage space, and are inconvenient to use and move; Placement of laboratory instrument racks, commonly used laboratory instrument racks usually can only store one kind of experimental instrument, and the function is relatively single; various types of equipment need to be prepared when doing experiments, and the operation is troublesome; during the experiment, when the liquid in the beaker is heated, The beaker is unreliable, and it is easy to tip over. If the liquid medicine is spilled on the test bench, it will pollute the test bench. If it is spilled on the skin, it is likely to burn the skin, which has a certain risk of operation.
