Multifunctional teaching device

Abstract

The invention relates to the technical field of teaching aids, in particular to a multifunctional teaching device. The multifunctional teaching device comprises a bottom frame, a motor, a hydraulic cylinder and a display board. The hydraulic cylinder drives a hydraulic rod to move up and down telescopically, the bottom end of the hydraulic rod is fixed, the hydraulic rod reversely drives the hydraulic cylinder, the hydraulic cylinder moves up and down, the hydraulic cylinder drives a connecting plate, the connecting plate drives a sliding block to slide up and down on a sliding rod, the sliding block slides on the sliding rod to drive a force arm, the force arm drives a mounting rod to drive the display plate to move up and down, and the display plate moves up and down to bring convenienceto writing work of teachers. According to the multifunctional teaching device, the problems that a teacher needs to stand on tiptoe when writing on a blackboard and needs to squat when writing at thebottommost end are solved, so that the working efficiency is improved, meanwhile, the use flexibility of the multifunctional teaching device is improved by adjusting the vertical height of the display plate, and the height can be adjusted so as to achieve a better display effect.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a multifunctional teaching device. Background technique [0002] During the teaching process, teachers need to display relevant knowledge points and problems so that students can watch and learn to think. At present, teaching devices are usually used to help teachers implement the display. [0003] However, the existing teaching device has a big problem in the use process. When the existing teaching device is carrying out the writing board, the surface of the device is not smooth enough, and it is easy to produce reflections, which is not conducive to students' viewing. The device cannot be rotated, which is not conducive to the communication and interaction between teachers and students, which reduces the teaching effect, and cannot be displayed to students from a wider viewing angle. The existing teaching device cannot be adjusted up and down, and the use is not flexible...
