Abstract

The invention discloses a physical experiment teaching device, and the device comprises a base, a second baffle and a top plate; a servo motor is installed in the base, a second bevel gear is arrangedon the side of the first bevel gear, a sleeve plate is installed on a second rotating shaft, and the lower end of a limiting rod is located in a limiting groove. A sleeve rod is fixed to the lower end face of the top plate, a full gear is fixed to the outer wall of a fifth rotating shaft, an annular through hole is formed in the top of the top plate, and an electromagnet, a control switch and a battery are sequentially arranged at the top of the demonstration table from left to right. According to the teaching device, the height of the demonstration table can be adjusted according to the height of a teacher, it is guaranteed that the teacher comfortably performs a demonstration experiment, meanwhile, the demonstration table can be rotated to the side of a student, the student can conveniently observe the experiment phenomenon at a short distance, and therefore the student can better receive knowledge.

Description

technical field [0001] The invention relates to the technical field of physics experiments, in particular to a physics experiment teaching device. Background technique [0002] The physics experiment is to enable the theoretical knowledge in the textbook to be demonstrated through real objects, so that students can learn more intuitively, and at the same time can promote students' interest, and the conversion of magnetic force into buoyancy is an important experiment in physics. The existing magnetic force There are following problems in converting into buoyancy teaching demonstration device: [0003] 1. Most of the existing teaching demonstration devices converted from magnetic force into buoyancy cannot be adjusted in height, so that the height of the teaching demonstration device cannot be adjusted according to the height of the teacher, and the teacher cannot demonstrate the experiment at a comfortable height; [0004] 2. The existing teaching and demonstration device f...
