AI Technical Summary

Technical Problem

The existing light propagation experimental device is unstable during the paper jamming process, the experimental effect is not good, and the experimental process cannot free both hands, making it difficult to observe the experimental phenomenon.

Method used

A magnetic multi-functional light transmission teaching aid was designed, including a base plate, a card slot, a card plate with holes, a card plate, a straight rod and a light source. The card slot and the base plate are matched by magnetic suction, and the card plate with holes can be moved, and the base plate is on With scales, transparent cover and tower incense are used to verify the light propagation path.

Benefits of technology

The stability and portability of the experimental device are realized, allowing the experimenter to liberate his hands, verify the light propagation through straight rods and smoke, significantly improving the experimental effect, and the transparent cover can be used as a storage box.

Abstract

The utility model discloses a magnetic type multifunctional light propagation teaching aid, which relates to the technical field of scientific teaching experiment devices and comprises a bottom plate, a clamping groove, a perforated clamping plate, a clamping plate, a straight rod and a light source. The clamping groove is formed in the bottom plate and can move left and right on the bottom plate. The perforated clamping plate and the clamping plate are arranged in the clamping groove and can move back and forth in the clamping groove; the number of the clamping plates with the holes is at least three. The positions of the small holes of the clamping plates with the holes are the same, and the diameters of the small holes are the same and are larger than the diameter of the straight rod. And the clamping plate is arranged at the rear end of the bottom plate. The magnetic type multifunctional light propagation teaching aid can liberate two hands of an experimenter, and is convenient for overall observation of an experiment in the experiment; students can have visual feelings, and the experiment effect is obvious; the stability is good, the operation is convenient, and the storage and the carrying are convenient.
