An imaging experiment teaching device for middle school physics learning

Abstract

The invention discloses an imaging experiment teaching device for middle school physics studying. The device comprises the components of a bearing base, an imaging device, adjusting screws, a bull gear, a movable seat, a light source device, a convex lens, a pinion and a first rocking bar. The top of the bearing seat is provided with an adjusting trough. One end of the adjusting trough is providedwith the imaging device at one end of the adjusting trough. The adjusting trough is internally provided with the adjusting screws. The adjusting screws comprise a first adjusting screw and a second adjusting screw. The first adjusting screw and the second adjusting screw are symmetrically arranged. The imaging experiment teaching device has advantages of reasonable and simple structure, and highconvenience in use. Rotation of gears and screws is used for performing adjustment, thereby effectively improving adjusting stability of the imaging experiment teaching device and reducing experimentoperation difficulty. The diameter of the bull gear is two times of that of the pinion so that adjustment precision is effectively improved. Rolling protection and dust eliminating are performed on animaging screen, thereby ensuring high imaging sharpness of the imaging screen, improving teaching effect of a physics imaging experiment, and realizing higher practicability.

Description

Technical field: [0001] The present invention relates to the technical field of physical experimental teaching equipment, and in particular, to a medium physics imaging experiment teaching device. Background technique: [0002] Experimental physics is relative to theoretical physics, theoretical physics is the subject discipline of the basic laws of naturally unknown material structure, interaction and material movement, and experimental physics mainly explores the material world and natural law from experiments. In secondary school physics teaching, it is mainly based on teaching theory knowledge, but while teaching theory knowledge, it will accompany the physical experiment explanation and operation, and the secondary school will let students take experiments with teachers to go to special physical laboratories, assist teachers or Help students conduct experiments, deepen the experimental teaching effect, physical imaging experiments are one of the important knowledge points of...

Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of imaging experiment teaching device for middle school physics learning in order to solve the above problems, which solves the problem that the existing imaging experiment teaching device adopts manual sliding adjustment when adjusting the distance between candles, screens and convex lenses. The control is difficult, which makes the adjustment of the distance between the candle, the screen and the convex lens take a long time, and the adjustment accuracy is poor, which affects the accuracy of the experiment and the effect of the physical imaging experiment teaching, and the problem of poor practicability
