Intelligent blackboard for teaching

Abstract

The invention discloses an intelligent blackboard for teaching. The intelligent blackboard for teaching comprises a base, wherein a double-shaft electromotor is arranged in the middle of the top end of the base; rotary shafts are coaxially connected to the left end and the right end of the double-shaft electromotor; lifting devices are arranged at opposite ends of the two rotary shafts; a frame isfixedly connected to the upper parts of face-to-face sides of the two lifting devices; a dedusting device is arranged on one side of the bottom end of the frame; an electronic screen is arranged in the middle in the frame; the upper end and the lower end of the electronic screen are fixedly connected with the frame through symmetrically arranged vertical rods; and blackboards arranged in the frame are arranged on the left side and the right side of the electronic screen; the two lifting devices comprise second bevel gears; and the two second bevel gears sleeve at one ends of the rotary shaftsintegrated with the second bevel gears. The intelligent blackboard for teaching provided by the invention is convenient to use; and the electronic board and the common blackboards are combined, so that the teaching quality is improved, the height can be freely adjusted to suitable for teachers in different heights, and no dust is fallen to affect the health of the teachers when the blackboards are wiped.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to an intelligent blackboard for teaching. Background technique [0002] At present, in the teaching activities of many primary and secondary schools and some colleges and universities, teachers still mainly rely on the traditional blackboard and chalk to explain or demonstrate the teaching content when giving lectures. Although this teaching method is flexible in use, it is low in use and maintenance costs. , but at the same time, there are rigid information transmission methods, high labor intensity for teachers, and a large amount of dust pollution, which leads to relatively low teaching quality. The smart tablet completely avoids the disadvantages of dust pollution, high labor intensity of teachers and single information transmission mode that are easy to appear in the traditional blackboard teaching. It is a relatively advanced teaching aid at present, but the cost o...

Problems solved by technology

[0005] The purpose of the present invention is to provide an intelligent blackboard for teaching, which is easy to use, combines the electronic board with the ordinary blackboard to improve the teaching quality, can adjust the height freely, makes it suitable for teachers of different heights, and will not drop when wiping the blackboard The advantage of dust affecting the health of teachers solves the problem that the blackboard is inconvenient to slide and cannot be adjusted in height, making it unsuitable for teachers of different heights. When wiping the blackboard, it is easy to cause a lot of dust, which affects the health of teachers and pollutes the environment.
