技术领域
本实用新型涉及一种教学用具,具体地说是一种多功能防尘黑板擦。
背景技术
目前,学校的学生每当在教室上课,所用现有普通黑板擦擦黑板时,无论老师还是同学都要用手捂着鼻子、嘴巴,因为所擦下的粉笔尘是漫天飞,吸多了对身体不好,另外经常有个子矮的同学值日时,擦黑板对较高的地方却擦不到,又蹦又跳也难以擦干净,所以很有必要生产一种既使用方便又防尘的多功能黑板擦。
发明内容
本实用新型的目的是:针对现有普通黑板擦的缺陷,提供一种多功能防尘黑板擦。
本实用新型是这样实现的:一种多功能防尘黑板擦,由伸缩把柄,手柄,擦体,防尘罩,转轴组成,其特征是:在手柄的上方通过转轴连接伸缩把柄,下方连接绒布擦体,在手柄与擦体交接处的周边上连接一个喇叭形防尘罩。
本实用新型的有益效果是:结构简单,成本低廉,使用方便,使用时只用手抓住手柄,擦黑板时,黑板擦四周的粉笔尘会被喇叭形防尘罩罩住,起到防尘作用,在黑板较高的地方可以拉开伸缩把柄,就可像涮墙一样擦黑板。
附图说明
图1为本实用新型结构示意图。
附图中:1、伸缩把柄,2、手柄,3、擦体,4、防尘罩,5、转轴。
具体实施方式
如图1所示,本实用新型由伸缩把柄,手柄,擦体,防尘罩,转轴组成,在手柄2的上方通过转轴5连接伸缩把柄1,下方连接绒布擦体3,在手柄2与擦体3交接处的周边上连接一个喇叭形防尘罩4。
使用时,只需用手握住手柄2或拉出伸缩把柄1,就可方便地近距离或较远距离的擦黑板,防尘、防灰、干净卫生。
