Description

一种新型的黑板
技术领域
本实用新型涉及一种黑板,具体说是一种粉末槽可自由伸缩的黑板。
背景技术
黑板是教学的必设施,普通黑板下方的粉末收集凹槽固定不变不能调节,粉笔末不便于打扫,并且凹槽面积比较小,粉笔末容易落到地上,影响教室卫生。
发明内容
本实用新型的目的便是提供一种粉末槽可自由伸缩的黑板。
为了实现上述目的,本实用新型的粉末挡板插在黑板底部的长条形开口内,在所述粉末挡板上方一侧的长条形开口内安装粉末擦,支撑杆安装在所述粉末挡板下方的黑板上,所述支撑杆外端上方设置挡块,滚轴的两端放置在支撑杆上对粉末挡板进行支撑。
通过以上设置,本实用新型的粉末槽可自由伸缩,可根据使用情况调节粉末槽,粉末擦便于清理粉末,使用清洁更方便快捷。
附图说明
现结合附图对本实用新型做进一步说明。
图1为本实用新型的结构示意图。
图中:1、粉末挡板,2、黑板,3、长条形开口,4、粉末擦,5、支撑杆,6、挡块,7、滚轴。
具体实施方式
如图1所示,本实用新型的粉末挡板1插在黑板2底部的长条形开口3内,在所述粉末挡板1上方一侧的长条形开口3内安装粉末擦4,粉末擦4可在粉末挡板1上滑动便于清理,支撑杆5安装在所述粉末挡板1下方的黑板1上,所述支撑杆5外端上方设置挡块6,滚轴7的两端放置在支撑杆5上对粉末挡板1进行支撑。通过以上设置,粉末挡板1可在长条形开口3内滑动伸缩,滚轴7方便粉末挡板1滑动。
