Description

一种黑板
[技术领域]
本实用新型涉及教学用具，特别是一种黑板。
[背景技术]
现有的黑板上的粉笔用黑板擦来擦，主要缺点是将黑板擦来回擦几遍时，脱落的粉飞向空气，污染环境。
[发明内容]
为了解决上述不足，本实用新型提供一种结构简单、使用方便的黑板。
一种黑板由黑板、黑板擦、回收盒组成，所述的黑板上下两边边缘设有滑槽，黑板左侧设有挡板，黑板左端设有弹性拉板，拉板中间设有凹槽，拉板下端设有回收盒，黑板右侧设有活动挡板，黑板擦插入黑板上下两边边缘滑槽内。
本实用新型的有益效果是：本实用新型使用时将黑板擦通过活动挡板插入上下两边边缘滑槽内，顺着上下两边边缘滑槽进行左右推拉，然后将黑板擦停在拉板下面，抓住黑板擦的把手，将黑板擦向外拉，这时拉板也同时拉开，并用力弹回去，使粘在黑板擦的粉立即脱落在回收盒内；本实用新型左右来回几次就可以擦掉黑板上的内容，无污染，结构简单，使用方便等特点。
