Anti-knock-down iron stand for high school physics experiment teaching

Abstract

The invention discloses an anti-knock-down iron stand for high school physics experiment teaching. The anti-knock-down iron stand comprises a bottom plate, wherein a vertical rod is arranged at one end of the surface of the bottom plate, a sliding sleeve is arranged on the vertical rod, a first supporting rod and a second supporting rod are respectively arranged on the two sides of the sliding sleeve, an iron ring is arranged at the top end of the first supporting rod, fixing rods are arranged on the two sides of the iron ring, a protection frame is arranged on the fixing rod, a protection plate is arranged on the surface of the bottom plate, sliding grooves are formed in the two sides of the inner wall of the protection plate, sliding strips are arranged at the two ends of a drawing plate, and are embedded in the sliding grooves, a placing plate is arranged at the upper end of the drawing plate, a supporting leg is arranged at the bottom end of the drawing plate, an opening for makingthe supporting leg move is formed in the bottom plate, an adjusting button for adjusting a plug pin is arranged on one side outside the opening, and a base is arranged at the bottom end of the bottomplate. According to the invention, with the anti-knock-down iron stand, an alcohol lamp can be placed conveniently, and is placed stably and is not likely to be touched, and a to-be-heated heating instrument can be replaced rapidly, so the use is convenient.

Description

technical field [0001] The invention relates to the technical field of physics teaching, in particular to an anti-knock iron platform for high school physics experiment teaching. Background technique [0002] High school physics teachers often use iron stands when they are teaching. Iron stands are generally used for experimental operations such as filtration, heating, and titration. They are one of the most widely used instruments in physics and chemistry experiments. The existing iron stands have a single structure. There is no effective fixed protection for the placement of alcohol lamps, and it is prone to tipping over. In addition, when heating different heating instruments on a general iron stand, it is necessary to disassemble the instrument first, and then adjust the clamps of different instruments to move up and down, left and right for heating. It is very troublesome to use. Contents of the invention [0003] The purpose of the present invention is to provide an...
