Abstract

The invention discloses an electronic cradle used in a physical experiment and relates to the technical field of manufacturing of teaching aids. The electronic cradle comprises a cradle body, wherein a core body is mounted in the cradle body; a chamber for accommodating a battery is formed in the core body; a spring is arranged at the bottom of the chamber; a lamp holder communicated with the chamber through a guide body block is arranged at the top of the core body; a cradle lamp extending out of the cradle body is mounted on the lamp holder; the core body is connected with a base through a screw rod arranged at the bottom. Compared with the prior art, the electronic cradle disclosed by the invention can solve the problem that an existing light source used in the physical experiment is a cradle, is poor in stability and pollutes indoor air.

Description

technical field [0001] The invention relates to the technical field of teaching appliance manufacturing, in particular to an electronic candle used in convex lens imaging experiments and plane mirror experiments. Background technique [0002] Convex lens imaging experiments and plane mirror experiments are important physical experiments in middle school textbooks. At present, in teaching, for clear imaging, the light source used in physical experiments such as convex lens imaging experiments and plane mirror experiments is candles. Using candles as light sources has the following shortcomings: 1. In the experiment, the curtains of the classroom should be closed. The gas and black smoke produced by the burning of candles will pollute the indoor air; The height of the image of the flame is inconvenient to measure, and the position of the clearest image is not easy to determine; 3, the paraffin wax dripped on the desktop and the ground is difficult to clean up. Contents of th...
