Abstract

一种磁性黑板揩，一块由揩擦物制成的黑板揩，其黑板揩内安装磁铁，磁性黑板揩与钢制黑板相配合。本黑板楷始终与钢制黑板相贴，一是揩黑板时使用方便，随时可用，污染少；二是揩黑板不需压紧力，仅需拖动力，有利于采用机械或电动机构带动黑板揩，实现自动或半自动揩黑板，文明、卫生、方便、省力。

Description

磁性黑板揩    
                       技术领域
本实用新型涉及黑板楷，用于钢制黑板配套，属于文教用品。
                       背景技术
黑板是文教的常用工具之一，近年来又发展了绿板(绿色)、白板(白色)等书写板，制板材料从木板发展为钢板，写字的笔除了传统的粉笔以外，也开发了各种无尘水笔等。钢制黑板比较光滑，但擦黑板仍比较麻烦，而且不卫生，擦完黑板后，黑板揩需要地方放置，又会污染放置的地方。
                      发明内容
本实用新型为了克服已有技术的缺陷，提供一种磁性黑板揩，所述磁性黑板揩的技术方案是：一块由揩擦物制成的黑板揩，其特征在于黑板揩内安装磁铁，磁性黑板揩与钢制黑板(包括绿板和白板等)相配合。由于在黑板揩中嵌了磁铁，成为磁性黑板揩，磁性黑板揩始终贴在钢制黑板上，有如下优点：一是揩黑板时使用方便，随时可用，污染少；二是揩黑板不需压紧力，仅需拖动力，有利于采用机械或电动机构带动黑板揩，实现自动或半自动揩黑板，文明、卫生、方便、省力。
                      附图说明
图1是本实用新型磁性黑板揩构造示意图。
                     具体实施方式
本实用新型公开了一种磁性黑板揩，一块由揩擦物1制成的黑板揩，其黑板揩内安装磁铁2，磁性黑板揩与钢制黑板相配合。所述的揩擦物是麻、草、棉、海绵等材料所制成，将有关材料制成绒布、布、毛巾等。并可在磁性黑板揩上连接电动吸尘器，更加卫生。

Claims (2)
