The invention is characterized in that a guide slot is installed on both sides of the blackboard, and an electric eraser is embedded in the guiding groove, and a side line slot is installed on the left and right sides of the blackboard. The electric wiping board mainly comprises a long rigid plate, and the inner side of the long hard plate is provided with a soft cotton eraser, each of which is connected with a guide wheel. There is a fixed pulley at the four corners of the guide slot. The side line slot is equipped with a winding wheel, a commutator and an electric motor. The guide wheel is connected with a pull line and a reverse drawing line. The CIS line and the reverse drawing line are connected to the winding wheel through a fixed pulley. The motor connects with a wire plug. When working, press the switch, the motor is electrified, drive the winding wheel to turn or reverse. When the winding wheel turns, the reverse line is long and the CIS line is twisted on the winding wheel, thus pulling the electric eraser to move to the right, and when the winding wheel is reversed, then the handwriting on the blackboard can be quickly wiped.

擦黑板神器
本专利技术涉及一种教学用品,尤其是一种便于擦黑板的擦黑板神器。
技术介绍
现行中小学教学所用的黑板,几乎都是另外配一个小小的黑板擦,擦黑板费时费力,很难擦干净,并且有些学生把黑板擦到处乱放,弄得粉笔灰到处都是,很不卫生,因此亟需一种便于擦黑板的擦黑板神器。
技术实现思路
本专利技术的目的在于提供一种擦黑板神器,可以快捷地擦干净黑板。本专利技术通过以下技术方案实现:本专利技术擦黑板神器,主要由导向槽、黑板、电动板擦、顺拉线、侧线槽、绕线轮、换向器、电动机、开关、逆拉线、定滑轮、电线插头构成,其特征是:在黑板的上下两边各安装一个导向槽,导向槽内嵌有一根电动板擦,在黑板的左右两边各安装一个侧线槽。电动擦板主要包括一根长条硬板,长条硬板内侧设有软棉擦,两头各连接一个导向轮。导向轮的主体是一个圆形的导向筒,导向筒内设有一根弹簧,导向筒口边安装一个上行轮,压在弹簧上面,导向筒的下方设有一个下行轮。导向槽的横截面是“”形的,由上挡板、上槽壁、槽内腔、后槽壁、下挡板和下槽壁构成,将导向轮嵌入导向槽的内腔中,上行轮紧贴导向槽的上槽壁,下行轮紧贴下槽壁,弹簧的弹力使电动板擦的软棉擦紧贴黑板。导向槽与侧线槽构成一个矩形,四角槽内各设有一个定滑轮,一边的侧线槽内装有绕线轮、换向器、电动机和开关,导向轮上连接有顺拉线和逆拉线,顺拉线和逆拉线穿过定滑轮连接在绕线轮上,电动机连接有电线插头。工作时,按下开关,电动机通电,带动绕线轮顺转或逆转,绕线轮顺转时,逆拉线放长,顺拉线缠绕在绕线轮上,从而拉动电动板擦向右移动,绕线轮逆转时,则反之,电动擦板向左移动。电动擦板移到侧线槽边时, ...
