Abstract

本实用新型公开了一种带有黑板擦的黑板,属于教学用具,特别是可以减轻擦黑板时粉末四处飞扬的黑板。该带有黑板擦的黑板,包括:黑板、黑板擦,其特征是:在黑板上部和底部分别固定安装一排沟槽,黑板擦的长度与黑板的宽度相同,板擦两端通过两个轴承套在黑板上、下的沟槽内,黑板擦的擦拭部分与黑板表面紧紧接触,黑板擦的手持部分外侧安装有手持把手。本实用新型的有益效果是:由于黑板擦长度与黑板宽度一致,使擦拭部分从黑板一侧移动到另一侧时可覆盖擦拭整个黑板,大大提高了擦黑板的效率;另外由于擦拭过程中仅需将黑板擦从黑板一侧移动到另一侧,然后再反方向移动,较普通小型板擦移动次数少,这样可大大减轻粉末飞扬的现象。

Description

带有黑板擦的黑板
技术领域
本实用新型属于教学用具,特别是可以使清洁效率很高且减轻粉末四处飞扬的黑板擦。
背景技术
现在普遍使用的黑板擦体积小,黑板上写的东西较多时擦起来比较费力费时,而且这种黑板擦快速在黑板表面来回移动,容易导致教室内粉末飞扬,使学生呼吸不畅。
实用新型内容
为了克服黑板擦擦黑板效率低且容易产生粉末飞扬现象的不足,本实用新型提供一种带有黑板擦的黑板,该带有黑板擦的黑板可大大提高擦黑板的效率,且减少擦黑板过程中教室内的粉尘。
本实用新型解决其技术问题所采用的技术方案是:一种带有黑板擦的黑板,包括:黑板、黑板擦,其特征是:在黑板上部和底部分别固定安装一排沟槽,黑板擦的长度与黑板的宽度相同,板擦两端通过两个轴承套在黑板上、下的沟槽内,黑板擦的擦拭部分与黑板表面紧紧接触,黑板擦的手持部分外侧安装有手持把手。
本实用新型的有益效果是:由于黑板擦长度与黑板宽度一致,使擦拭部分从黑板一侧移动到另一侧时可覆盖擦拭整个黑板,大大提高了擦黑板的效率;另外由于擦拭过程中仅需将黑板擦从黑板一侧移动到另一侧,然后再反方向移动,较普通小型板擦移动次数少,这样可大大减轻粉末飞扬的现象。
附图说明
图1为本实用新型的结构示意图,
图中,1.黑板,2.沟槽,3.轴承,4.擦拭部分,5.手持部分,6.手持把手。
具体实施方式
本实用新型的具体实施方式是,如图所示:
实施例1,一种带有黑板擦的黑板,包括:黑板1、黑板擦,其特征是:在黑板上部和底部分别固定安装一排沟槽2,黑板擦的长度与黑板的宽度相同,板擦两端通过两个轴承3套在黑板上、下的沟槽内,黑板擦的擦拭部分4与黑板表面紧紧接触,黑板擦的手持部分5外侧安装有手持把手6。
