Description

一种新型黑板擦
技术领域
本实用新型属于一种教学办公用品,特别涉及一种新型黑板擦。
背景技术
目前,虽然电气化教学已经比较普遍,但传统的板书教学的作用并不能被其取代,因此黑板和黑板擦在教学中又成为必不可少的工具,黑板擦一般多由底座和毛刷组成,而普通黑板擦的底座和毛刷一般为固定连接,当毛刷损坏时黑板擦也随之报废,造成很大浪费。
实用新型内容
本实用新型的技术任务是针对以上现有技术不足而提供了一种新型黑板擦。
本实用新型解决其技术问题所采用的技术方案是:一种新型黑板擦,包括板擦底座和擦子,所述板擦底座底部开有倒梯形卡槽,所述擦子由粘板和毛刷固定连接在一起组成,所述粘板上固定设有倒梯形卡块。
进一步,所述擦子通过将擦子上的倒梯形卡块插入板擦底座上的倒梯形卡槽内来实现连接,当擦子磨损严重时可以拆换。
该实用新型设计合理,使用方便。
附图说明
附图1为本实用新型结构示意图。
具体实施方式
参照说明书附图对本实用新型作以下详细说明:
如图1所示,一种新型黑板擦,包括板擦底座1和擦子2,所述板擦底座1底部开有倒梯形卡槽,所述擦子2由粘板和毛刷3固定连接在一起组成,所述粘板上固定设有倒梯形卡块4。
进一步,所述擦子2通过将擦子上的倒梯形卡块4插入板擦底座1上的倒梯形卡槽内来实现连接,当擦子2磨损严重时可以拆换。
