The invention provides a multifunctional blackboard. The multifunctional blackboard comprises a blackboard body and a writing surface, wherein the blackboard body is embedded into a frame, and the writing surface, embedded into the frame, of the blackboard body is a mesh; a rear cover plate is arranged on the rear portion of the blackboard body; a left steering electric motor and a right steering electric motor are arranged on the two lower corners of the inner side of the rear cover plate; belt wheels are arranged on the electric motors; each of the two corners of the inner side of the rear cover plate is provided with a belt wheel; a transmission belt is wound on the four belt wheels in a crossing mode; a blackboard wiper with the width same as that of the writing surface is vertically and tightly attached to the writing surface of the blackboard body; the two ends of the blackboard wiper are fixed to the transmission belt of the rear cover plate of the blackboard body; and control buttons are arranged on the two sides of a lower frame body of the frame. Supporting rods are arranged between an upper frame body and the lower frame body of the blackboard body and are triangular prisms; the mesh-shaped surface of the writing surface of the blackboard body is a black metal thin-mesh surface; and a drawer type chalk tray collection box is arranged at the bottom of the blackboard body. The multifunctional blackboard can effectively solve the problems that the writing surface is unsmooth in writing and reflects light, the efficiency of manually wiping the blackboard body is low, and dust tray cannot be contained in a concentrated mode, and consequently pollution is caused.
Description
technical field [0001] The invention relates to a teaching tool, in particular to a multifunctional blackboard. Background technique [0002] Blackboard is a tool commonly used in teaching and office work, but there are many shortcomings in the process of use. Usually the writing surface of the blackboard we use for teaching has problems of reflection and not smooth writing. Manually wiping the blackboard is not only inefficient, but also often cannot wipe the height of the blackboard due to short stature, and the chalk dust scattered around when wiping the blackboard will cause dust pollution and bring great harm to human health. Contents of the invention [0003] The invention provides a multifunctional blackboard, which can effectively solve the pollution problems caused by unsmooth writing on the writing surface, light reflection, low efficiency of manually wiping the blackboard, and inability to collect chalk dust in a centralized manner. [0004] The technical sche...
