Description

无尘黑板擦
技术领域:
本实用新型是涉及黑板擦结构的改进。
背景技术:
现有黑板擦擦黑板时会使粉笔尘四溅,影响教室内卫生,危害同学们的身体健康;而且,当黑板擦使用过一段时间后,用这种黑板擦不能达到将黑板擦干净的效果。
实用新型内容:
本实用新型就是针对上述问题,提供一种使用黑板擦时,黑板上粉笔灰不向外扩散,使黑板擦可持久使用的无尘黑板擦。
为实现上述目的,本实用新型采用如下技术方案,本实用新型包括壳体,其结构要点壳体顶端的转动轴外设置有滚动毛毡,与毛毡相接触的毛刷设置在壳体内的调整螺栓上;壳体侧方设置有胶塞。
本实用新型的有益效果:
使用本实用新型的无尘黑板擦擦黑板时,毛毡滚动、粉笔灰会随着毛毡转动到黑板擦壳体内部,并被壳体内部的毛刷刷到壳体内,粉笔灰达到一定数量时,可以打开胶塞倒掉;使黑板上的笔灰不向外扩散,保护了师生健康,并使黑板擦可持久使用。
附图说明:
图1是本实用新型的结构示意图。
具体实施方式:
本实用新型包括壳体2,壳体2顶端的转动轴6外设置有滚动毛毡7,与毛毡7相接触的毛刷5设置在壳体2内的调整螺栓3上;壳体2侧方设置有胶塞1。
为保持毛毡7平稳运动,设置有三个转动轴6。
调整螺栓3可设置两个。
调整螺栓3外毛刷5的底部设置有复位弹簧4;使毛刷5始终同毛毡7相接触,保证清洁效果。
