Description

清洁粉笔套
技术领域
本实用新型属于教学用品技术领域,涉及一种清洁粉笔套。
背景技术
粉笔在书写过程中会污染手指,甚至对皮肤造成损害,粉笔头过于短小时还不便于手持,造成浪费,为此,人们设计了粉笔套。现有技术粉笔套有多种,结构不同,成本不同,使用效果也不相同,但一般存在结构较复杂或使用不便利的问题。
发明内容
本实用新型的目的是提供一种结构简单、使用方便的清洁粉笔套。
本实用新型是这样实现的:一种清洁粉笔套,包括套体,该套体具有弹性,其前半部开设缝隙槽,缝隙槽的外部设置弹性皮套。
作为本实用新型的进一步改进,该缝隙槽为三条,均匀分布在套体的圆周方向。
本实用新型由套体和皮套两部分构成,套体前部开设缝隙槽便于扩大内径涨缩的范围,通过皮套的收缩力可使套体前部内径局部变小,使用时,在套体内放置粉笔,由皮套裹紧套体前部从而固定粉笔,具有结构简单和使用方便的有益效果。
附图说明
图1为本实用新型的结构示意图。
图2为图1的A-A剖面图。
图中,1、套体,2、缝隙槽,3、皮套。
具体实施方式
以下结合附图对本实用新型的具体实施方式进一步说明。如图所示,套体1的前半部开设缝隙槽2,缝隙槽2的外部包裹弹性皮套3,缝隙槽2为三条,均匀分布在套体1的圆周方向。套体1采用具有一定弹性的材料制作,其内径略大于粉笔大头的外径,使用时,可由套体1后部装入粉笔,推到套体1前端露出适当尺寸,在皮套3的弹性包裹作用下,套体1前部的缝隙槽2会缩小,内径变小,从而固定住粉笔,当粉笔随着使用缩短时,可由套体1后部施加外力,推动粉笔向外移动,继续使用。

Claims (2)

1.一种清洁粉笔套,包括套体(1),其特征在于:该套体(1)具有弹性,其前半部开设缝隙槽(2),缝隙槽(2)的外部设置弹性皮套(3)。
2.根据权利要求1所述的清洁粉笔套,其特征在于:该缝隙槽(2)为三条,均匀分布在套体(1)的圆周方向。
