Abstract

The invention discloses a multifunctional teaching blackboard and belongs to the technical field of teaching tools. The multifunctional teaching blackboard comprises a blackboard body, a lifting mechanism, an erasing mechanism, a line drawing mechanism and a control system. The blackboard body comprises a main body, an upper baffle and a lower baffle. The lifting mechanism is arranged on the blackboard body and comprises a transverse rod and a lifting drive device. The erasing device comprises a first sliding device, a blackboard eraser clamping device and a blackboard eraser. The line drawingmechanism comprises a chalk clamping device, chalk and a second sliding device. The control system is arranged on the blackboard body and connected with the lifting drive device, a first horizontal drive device and a second horizontal drive device. By means of the multifunctional teaching blackboard, the problems that as for a traditional blackboard, chalk handwriting needs to be manually erased,four-lined grids are drawn manually and consequently great inconvenience is brought to teaching are solved.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a multifunctional teaching blackboard. Background technique [0002] At present, although multimedia teaching has been widely used, many subjects still need to write a lot of blackboard writing, such as mathematics, physics, chemistry formula derivation process, etc. Therefore, the blackboard is still an indispensable teaching tool in the classroom. The traditional blackboard needs to manually erase the chalk writing on the board before rewriting; in this way, not only the erasing efficiency is low, but also the person who wipes the blackboard inhales a large amount of chalk dust, which affects physical and mental health. [0003] When teaching English, teachers usually need to draw four lines with equal intervals on the blackboard, which is called a four-line grid. Drawing a four-line grid is generally carried out by manually holding a ruler. Therefore, the drawn lines c...
