Showing stand for physics teaching

Abstract

The invention relates to the field of physics teaching and in particular relates to a showing stand for physics teaching. The showing stand comprises a display, loudspeakers, fixed rods, rotating rods, a first rotating shaft, a second rotating shaft, vertical rods, inner connecting rods, an illuminating lamp and fixing clamps, wherein the display is embedded in a wall; totally two loudspeakers are respectively embedded in two sides of the display; the two fixed rods are respectively arranged at the upper and lower positions on the left side of the display; the rotating rods and the fixed rods are rotationally connected with one another through the second rotating shaft; one rotating rod is arranged below the other rotating rod; middle positions of the two rotating rods are connected through the first rotating shaft; the two ends of the rotating rods are connected through the vertical rods; the inner connecting rods are arranged in parallel in the vertical rods; and the fixing clamps are respectively arranged below the inner connecting rods and below the top rotating rod. The showing stand disclosed by the invention is easy to mount and detach and can be telescopically folded on the wall surface due to an adjusting function, the occupied space is saved, and the operation is convenient. The illuminating lamp can be used for teaching illumination in a dimly lighted space, and the showing stand has excellent practicality.

Description

technical field [0001] The invention relates to the field of physics teaching, in particular to a display stand for physics teaching. Background technique [0002] Long before the Stone Age, people tried to understand the world: why objects fall to the ground, why different substances have different properties, and so on. The nature of the universe is also a mystery. For example, what laws do stars such as the earth, the sun, and the moon follow to move, and what forces determine these laws. Various theories have been proposed to try to explain the world, but most of them are wrong. These early theories look more like philosophical theories today, unlike today's theories that usually need to be proven by systematic experiments. Some of the theories proposed by Ptolemy and Aristotle are contrary to the facts we observe every day. Of course, there are exceptions. For example, many descriptions given by some philosophers and astronomers in India in terms of atomic theory and...
