Description

板书笔套
技术领域
本实用新型涉及一种板书笔套,特别是防止粉笔板书时易折断、污染手的套,属文化用品。
背景技术
目前,人们在黑板等上面板书时常用粉笔,由于其质软一是易折断,二是污染手,有时用到一定长度,因手指捏不住而白白丢弃,既造成浪费,又不利于环境卫生。
发明内容
针对现有技术不足,本实用新型提供了一种既节约板书笔,又干净卫生不污染手的笔套。
本实用新型解决其技术问题的方案是:由螺纹把笔管和笔头连接在一起构成笔套外壳。把挡圈、弹簧依次套在压杆上,通过笔管装配于笔管上方开口位置。挡圈固定在笔管内适当位置,起到支撑定位作用。弹簧一端由挡圈支撑,另一端固定在压杆上。胶套固定在笔头的内壁上,用于夹紧粉笔。
本实用新型的有益效果是:在粉笔外面套上笔套,一是解决了手的污染问题,二是解决了在板书过程中粉笔易折断的问题,三是起到了加长粉笔的作用,做到了节约。
附图说明
附图为本实用新型的结构示意图。
具体实施方式
如图所示,螺纹2把笔管11和笔头12连接在一起构成笔壳1。挡圈3、弹簧4依次套在压杆5上,通过笔管11连同挡圈3、弹簧4一起将压杆5装配在笔管11上端开口位置,并间隙配合。挡圈3固定在笔管11内适当位置,起到支撑弹簧4、定位压杆5的作用,弹簧4的另一端固定于压杆5上。胶套6固定在笔头12内壁上,用于夹紧粉笔7。
需要加装粉笔7时,旋开螺纹2,粉笔7的一端插入笔头12内的胶套6后,旋紧螺纹2,粉笔7另一端即和压杆5相连。粉笔7用到一定程度,由压杆5将其推出笔壳1外。
