本实用新型为了弥补现有技术的缺陷,提供了一种省力且能防止粉笔灰飘散的防尘黑板。
本实用新型是通过如下技术方案实现的:
一种防尘黑板,包括黑板面,其特征是:黑板面上下两端设置导轨,导轨内安装滑轮,毛刷的两端分别与滑轮拆分连接,毛刷的两侧安装防尘条,毛刷紧贴黑板面,黑板面下端的导轨外设有粉尘槽。
本实用新型的有益效果是:该防尘黑板结构简单,使用方便,能防止粉尘飘散,清洁卫生。
(四)附图说明
下面结合附图对本实用新型作进一步的说明。
附图1为本实用新型防尘黑板的结构示意图。
图中,1黑板面,2导轨,3滑轮,4毛刷,5防尘条,6粉尘槽。
(五)具体实施方式
附图为本实用新型的一种具体实施例。
如图1所示,该防尘黑板,包括黑板面1,黑板面1上下两端设置导轨2,导轨2内安装滑轮3,毛刷4的两端分别与滑轮3拆分连接,毛刷4的两侧安装防尘条5,毛刷4紧贴黑板面1,黑板面1下端的导轨外设有粉尘槽6。
