Controllable type blackboard capable of automatically brushing

Abstract

The invention discloses a controllable type blackboard capable of automatically brushing. The controllable type blackboard capable of automatically brushing comprises a blackboard rack main body, wherein the side end of the blackboard rack main body is equipped with a mounting column, and is fixed with a wall body; the blackboard rack main body is spaced with the wall body; the bottom end of the blackboard rack main body is equipped with a fixed base which is of a Z-shaped structure; a mounting connecting block is mounted on the fixed base; a control supporting frame is mounted at the top endof the mounting connecting block, and the mounting connecting block is positioned at the back end of the blackboard rack main body; and two ends of the inner side of the control supporting frame are equipped with longitudinal slide rails. The novel backboard mounting structure adopted by the scheme of the invention adopts an adsorbing type structure to work, adopts a novel electromagnetic adsorbing structure to adsorb a blackboard eraser, adopts a power transmission assembly at the back end to adsorb and control the blackboard eraser to perform track motion, realizes automatic erasing effect,is provided with an independent wireless control assembly, can be remotely controlled, also can perform connecting operation control on mobile phone APP, and can automatically control the blackboard eraser to erase.

Description

technical field [0001] The invention relates to the field of teaching appliances, in particular to a controllable automatic brushing blackboard. Background technique [0002] As we all know, the fully automatic blackboard is powered by four motors, two of which are installed on a frame as large as the blackboard, and a beam is moved up and down through a reducer, and the other two motors make a row of soft blankets make a circle. exercise and wipe off the chalk writing on the blackboard. There is a row of long box slots that can cover soft blankets and dust, and the user only needs to press the button to make it start and stop. Each soft blanket can be close to the blackboard or not close to the blackboard. There is a long box slot outside a row of beams. Therefore, when we need to wipe the blackboard, there is no need to manually use the blackboard eraser, but the switch can be controlled to move it to the place we need to automatically erase the chalk writing, which bri...
