Dust-free teaching blackboard facilitating mark removing

Abstract

The invention discloses a dust-free teaching blackboard facilitating mark removing in the technical field of teaching tools. The dust-free teaching blackboard facilitating mark removing comprises a blackboard framework. The front side and the rear side of an inner cavity of the blackboard frame are both provided with cross-shaped separation plates in a welded manner. The inner cavity of the blackboard frame is divided by the cross-shaped separation plates into four uniform teaching regions. According to the dust-free teaching blackboard facilitating mark removing, due to the characteristic that movable blackboard bodies can slide in the inner cavity of the teaching regions, a teacher can select the different movable blackboard bodies to teach according to teaching content, and students conveniently record a note; by means of the partitioned teaching regions, teaching requirements of teachers with different statures can be met, and the teacher can advantageously propel a teaching progress; and by means of the dust-free mark removing region arranged at the lower right corner, the explained teaching content is wiped, the phenomenon that dust flies due to the non-concentrated wiping regions is reduced, and the effect on physical health of the teachers and the students is reduced.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a dust-free teaching blackboard which is convenient for printing. Background technique [0002] The blackboard does not specifically refer to the black board surface. In the traditional sense, it is a plane that can be repeatedly written with chalk. The board surface is hard and is mostly used for teaching. Blackboards are generally made of wood or frosted glass. Writing material to write on. Mostly black, dark green, white or beige. From the surface shape, there are flat panels and arc panels. From the structural composition, there are bracket movable panels, push-pull panels, lifting panels, and magnetic blackboards. In terms of uses, there are teaching blackboards, office whiteboards, advertising panels, and display panels.. The teaching blackboard also has electronic blackboard, multi-functional combination board, combination push-pull blackboard, interactive electro...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing teaching blackboards are designed in one piece, and the teaching area on the top is relatively high. For teaching teachers with low height, they can only use the lower area of ​​the teaching blackboard during the course explanation process, which affects the progress of the teaching teacher's course explanation. At the same time, the teaching teacher needs to constantly wipe off the teaching content that has been explained in the process of explaining. Due to the limitation of the height of the teacher, most of the teachers can only use the lower teaching area, so that the records of the learners are wiped off by the teaching teacher before they have time to take notes. The teaching content that has been explained affects the learning efficiency of the learners. At the same time, there is no centralized dust removal area. When the teaching teacher erases the teaching content, it often causes dust to fly, which not only affects the health of the teaching teacher, but also affects the health of the learners. Good health, based on this, the present invention designs a dust-free teaching blackboard that is easy to print, to solve the above problems
