Intelligent blackboard with interchangeable positions of main screen and auxiliary screen

Abstract

The invention relates to the technical field of teaching aids, and discloses an intelligent blackboard with a main screen and an auxiliary screen interchangeable in position, the intelligent blackboard comprises a cross-shaped bottom plate located above the ground, universal wheels are fixedly installed on the lower surface of the cross-shaped bottom plate, a stable stand column is fixedly installed on the upper surface of the cross-shaped bottom plate, and an adjusting fixing device is arranged at the top of the stable stand column; a writing panel is fixedly installed on the inner side of the adjusting and fixing device, and a display screen is fixedly installed on the left side of the back face of the writing panel. According to the intelligent blackboard with the positions of the main screen and the auxiliary screen interchangeable, an electric push rod drives a push support and a push rod to drive a friction arc-shaped frame to be in friction with an annular pipe for fixing operation, a better friction limiting effect on a writing panel is achieved, the writing panel can be better fixed at any angle, and learning display operation can be better conducted; and teaching display operation can be better carried out, and better use is facilitated.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a smart blackboard with interchangeable main and secondary screens. Background technique [0002] The smart blackboard usually includes a spliced ​​electronic tablet and a writing board. The electronic tablet can be touch-operated to present teaching content in the form of pictures, videos, etc., and the writing board can be used for teachers to write blackboard writing and present teaching content in the form of blackboard writing. The electronic tablet and The combination of writing board can realize the combination of traditional teaching and electronic teaching, improve the teaching effect, help to carry out teaching operation more efficiently and quickly, and have more diversified teaching methods. [0003] For example, a smart blackboard with Chinese patent application number 201821437453.0 is basically described as follows: the smart blackboard is displayed through ...

Problems solved by technology

[0003] For example, a smart blackboard with Chinese patent application number 201821437453.0 is basically described as follows: the smart blackboard is displayed through the blackboard body, which is convenient for students to observe, helps students to learn better, and effectively improves students' learning ability. The enthusiasm for learning is conducive to better use and further improves the convenience in the use process; the existing smart blackboard generally uses a single-sided blackboard for writing and display, and it is difficult to better educate students. Display operation is not conducive to better teaching of wisdom to students, reduces the learning efficiency of students, and is not conducive to better use
