Description

一种擦拭黑板的工具,它是可以带在手指上的小型黑板擦。
通常使用的黑板擦都是将毡制板擦垫固定在板擦盖上。由于它尺寸较大,约在70mm×150mm左右,使用时,拿住板擦,必须放下粉笔或书本;不用时,放在讲桌上或黑板下边缘的接粉槽中,讲课过程中,常常需要寻找板擦,影响板书速度,分散学生注意力,也很不方便。
本实用新型的目的是设计一种可以带在教师手指上的小型黑板擦。
本实用新型的目的是这样实现的:板擦体的结构与现有技术相同,即用毡片制成毡垫,以胶带将毡垫缠紧,成为板擦垫,固定在擦盖上。本实用新型的特点是它的板擦垫小巧,尺寸不大于50mm,可以是方形、圆形、椭圆形等,而且在擦盖上固定有可以套在手指上的带子,最好是松紧带。
讲课时,将板擦上的带子套在右手中指、无名指和小指上,板擦垫一面朝外,不影响讲课、持教具、翻课本等。板书过程中出现笔误时,可随时用本擦抹去,不必放下粉笔,不必现找板擦,十分方便。
本实用新型的实施例结合以下附图说明:
图1是本实用新型正视图。
图2是图1的俯视图。
结合附图:本实用新型包括擦盖1、由毡片2和胶带3制成的擦垫,用钉4固定在擦盖1上的松紧带5。擦垫和擦盖的尺寸选择等于或稍小于50mm×50mm,松紧带的长度应能套住三个手指为宜。擦盖1可以木制或塑料制;擦垫可以用毡片或其它柔软吸尘材料。
