Description

易清理黑板
技术领域  本实用新型涉及一种教学用具。
背景技术  众所周知,黑板是教学过程中重要的用具之一,现有的黑板在擦拭时,教师和学生都是利用黑板擦进行擦拭,而现有的体积较小,在擦拭过程中费力,容易将双手弄脏,另外,在大扫除的时候,学生会将黑板利用湿抹布彻底擦拭一遍,而擦拭后需晾干,晾干的时间较长,如利用干抹布擦拭至干燥,非常费力。
发明内容  本实用新型的目的在于提供一种结构新颖、省力卫生、方便实用、操作简便、造价低廉、易于推广的易清理黑板。
本实用新型包括板面、边框、条形板、刷毛、弹簧以及拉绳,板面的外周边固接边框,边框外表面对称两侧面顶边处开设滑道,条形板通过滑道与两侧边框连接,条形板的内侧设有刷毛,条形板的顶端连接弹簧,弹簧的另一端与上侧边框相连,条形板的外侧面两端设有拉绳。
本实用新型是这样使用的:
使用者利用拉绳将条形板拉下,拉下的过程中条形板内侧的刷毛将板面清理一次,松开拉绳,由于弹簧的作用,条形板自动返回顶部,返回过程中再一次清理板面一次,上述动作反复使用,直至板面清理干净。
本实用新型与现有技术相比具有如下优点:结构新颖、省力卫生、方便实用、操作简便、造价低廉、易于推广。
附图说明图  1为本实用新型的立体示意简图。
具体实施方式  在图1所示的易清理黑板的立体示意简图中,板面1的外周边固接边框2,边框外表面对称两侧面顶边处开设滑道3,条形板4通过滑道与两侧边框连接,条形板的内侧设有刷毛5,条形板的顶端连接弹簧6,弹簧的另一端与上侧边框相连,条形板的外侧面两端设有拉绳7。
