Chemical standard experiment table for students

Abstract

The invention discloses a chemical standard experiment table for students. The experiment table comprises a framework (1), a table top (2), a side plate (3), an instruction case (4), a water feeding and discharging part (5) and a power supply unit (6), wherein the main body framework (1) of the experiment table is of a plastic steel structure, and the table top (2), the side plate (3) and the panel of the instruction case (4) are made of an imported solid-core physicochemical plate material and thermally fixed on the main body framework (1) via the king of hot glues imported from Germany by using a thermoforming machine, thereby forming the integral experiment table. The water feeding and discharging part (5) employs a high-quality test water tank, a copper chrome-plated triple water nozzle and a ceramic chip water valve. The power supply unit (6) is provided with a short circuit overload protection device which enables AC-DC voltage to be controlled in a range of 2 to 24 V and a maximum current to be 2A. The experiment table provided by the invention has the advantages of a firm and reliable integral body, a beautiful shape, acid and alkali resistance, high temperature resistance, water resistance, fire resistance, no leakage and obstruction at the water feeding and discharging part, integral insulation and no electric leakage and can be used as modern teaching equipment for chemical laboratories in middle schools.

Description

technical field [0001] The invention relates to modern teaching equipment of a chemical laboratory, in particular to a chemical standard student experiment table. Background technique [0002] At present, most of the test benches for students in school chemistry laboratories are wooden or steel-structured desk-shaped tables. After the experiment, the instruments must be put back into the instrument cabinet elsewhere, and the washing of the experimental utensils must also be carried out in the ordinary sink, which is very inconvenient. Contents of the invention [0003] The object of the present invention is to: provide a kind of chemical standard type student experiment bench, adopt new material, utilize new technology, the various functions such as the placement experiment of experiment operation instrument and washing etc. are integrated in experiment bench, customer service prior art defect, The experimental table is resistant to acid and alkali, high temperature, non-a...

Problems solved by technology

[0002] At present, most of the student experiment benches in school chemistry laboratories are desk-like desks with wooden or steel structures. After the experiment, the instruments have to be put back in the instrument cabinet elsewhere, and the washing of the experimental utensils also needs to be carried out in the ordinary sink, which is very inconvenient.
