Description

粉笔套
本实用新型属于教学用品,具体涉及一种粉笔套,适合与传统的粉笔配合使用。
目前,教师手持粉笔在黑板上写字,极易弄脏手指,同时也不卫生。
本实用新型的目的是,提供一种粉笔套,该套可避免粉笔弄脏教师的手指。
本实用新型是,在套筒一端内采用螺纹连接着一个设有防滑头的旋转杆,纵向设有开缝的另一端的外形为圆锥形,并采用螺纹连接着一个设有防滑纹的紧固圈。
下面结合附图,对本实用新型作进一步的描述。
图1是本实用新型的平面半剖视示意图。
如图1所示,本实用新型在套筒1一端内采用螺纹连接着一个设有防滑头6的旋转杆2。防滑头6的圆直径可以略大于旋转杆2的圆直径,也可与其直径相同,最好在防滑头6圆周表面设置防滑纹。纵向设有一条或三条开缝5的另一端的外形设成圆锥形4,并采用螺纹连接着一个设有防滑纹的紧固圈3。本套可选用略有弹性的无毒塑料制造。以上所述的开缝5,其长度占套筒1长度的二分之一或三分之一。
使用时,先将旋转杆2和紧固圈3旋下,把粉笔7装入套筒1并使粉笔小端7伸出一节,然后将紧固圈3套上旋紧,最后再把旋转杆2旋入套筒1顶住粉笔大端。当伸出的粉笔用完时,可旋松紧固圈3,通过转动旋转杆2即可将粉笔顶出。
本实用新型由于将粉笔装入套筒并由紧固圈和旋转杆控制粉笔的伸出长度,从而使该套可避免粉笔弄脏教师的手指。该套使用方便、卫生,结构简单,易于实施。
