Description

一种黑板擦
技术领域
本实用新型涉及一种教学用具,具体来讲是一种黑板擦。
背景技术
在给学生上课时,为便于理解和记忆,对于重点内容,老师会不时地用粉笔在黑板上进行书写,擦黑板时为了防止粉尘飞扬,大多采用湿布或黑板擦加水的方式进行擦除,但由于黑板擦体积小,经常需要长时间反复不停地擦拭,才能保证黑板的继续使用,所以会耽误时间并给值日生或老师带来很大不便。
实用新型内容
本实用新型的目的在于提供一种黑板擦,该黑板擦擦拭黑板效率高,省时省力。
本实用新型解决其技术问题所采取的技术方案是:一种黑板擦,包括黑板擦本体,所述的黑板擦本体一端与一支架相连接,所述的支架插入一滑槽内,所述的滑槽设在一滑轨上。
本实用新型的有益效果是:握住板擦沿滑轨的方向自黑板一侧向中间移动,便可一次性将整面黑板擦完,不但擦黑板时省时省力,而且可以减小传统方法擦黑板造成的粉尘飞扬对人体的危害和对环境的影响,短时间恢复黑板的正常使用。
附图说明
图1为本实用新型的结构示意图。
图中:1滑轨,2支架,3黑板擦本体。
具体实施方式
如图1所示。一种黑板擦,包括黑板擦本体3,所述的黑板擦本体3一端与一支架2相连接,所述的支架2插入一滑槽内,所述的滑槽设在一滑轨1上。滑轨1固定在黑板上方,黑板擦本体3长度与黑板高度相一致。
使用前,将黑板擦本体3推动至不影响在黑板上正常书写的位置,即黑板的左侧或右侧,当需要擦黑板时,握住黑板擦本体3,沿滑轨1的方向自黑板一侧向中间移动,由于黑板擦本体3刷毛与黑板直接接触,便可一次性将整面黑板擦完。
