Abstract

无尘磁性黑板,涉及一种无尘黑板。黑板2内安有磁珠1,磁珠1表面为白色,书写笔4内有磁铁3。本实用新型在黑板2内安有磁珠1,磁珠1表面为白色,书写笔4内有磁铁3。当书写者用书写笔4在有磁珠1的黑板2上书写时,磁珠在书写笔4内的磁性吸力下伸出黑板,由凸出的磁珠即可看出书写的内容。书写完后,向下压磁珠,磁珠即缩回到黑板内。采用本实用新型不会有粉笔灰飞扬,污染环境,损害师生健康的问题。

Description

无尘磁性黑板
技术领域
本实用新型涉及一种无尘黑板。
背景技术
现在教学多数还是使用黑板和粉笔,用粉笔板书后必须擦掉,而擦掉的粉笔灰到处飞扬,会严重影响师生的身体健康。
发明内容
本实用新型的目的是针对上述现状,旨在提供一种没有粉笔灰扬尘的无尘磁性黑板。
本实用新型目的的实现方式为,无尘磁性黑板,黑板2内安有磁珠1,磁珠1表面为白色,书写笔4内有磁铁3。
本实用新型在黑板2内安有磁珠1,磁珠1表面为白色,书写笔4内有磁铁3。当书写者用书写笔4在有磁珠1的黑板2上书写时,磁珠在书写笔4内的磁性吸力下伸出黑板,由凸出的磁珠即可看出书写的内容。书写完后,向下压磁珠,磁珠即缩回到黑板内。采用本实用新型不会有粉笔灰飞扬,污染环境,损害师生健康的问题。
附图说明
图1是本实用新型的黑板结构示意图
图2是本实用新型黑板的书写笔结构示意图
具体实施方式
参照图1,本实用新型的黑板2内安有磁珠1,参照图2,书写笔4内有磁铁3。当书写者用书写笔4在有磁珠1的黑板2上书写时,磁珠在书写笔4内的磁性吸力下伸出黑板,由凸出的磁珠即可看出书写的内容。书写完后,向下压磁珠,磁珠即缩回到黑板内。采用本实用新型不会有粉笔灰飞扬,污染环境,损害师生健康的问题。
