Description

免脱笔帽
技术领域
本实用新型涉及办公用品领域,具体为一种免脱笔帽。
背景技术
现有的笔帽在使用笔的时候都需要脱去,在经过多次脱去盖上后就有可能出现松脱,随即就有可能在不经意时将笔帽遗失以至笔尖不能得到有效保护。
发明内容
本实用新型的目的在于克服现有笔帽的缺陷,提供一种不用脱下即可使用的笔帽。
为了达到上述目的,本实用新型是这样实现的:一种免脱笔帽,其特征是:它包括套管、伸缩罩、滑块;套管上对称设有两个大小相同的滑槽,滑块分别设于两个滑槽内,两者过盈配合;伸缩罩呈圆锥形并设于套管内,其底部与滑块连结为一体;伸缩罩的顶部设有切口。
为了方便伸缩罩与笔尖之间的配合,伸缩罩由软质材料制成。
本实用新型采用上述设计,在不脱下套管的情况下可通过伸缩罩露出笔尖或是罩住笔尖,如此即可避免因笔帽松脱而引起的笔尖失去保护。
附图说明
图1为本实用新型收缩状态剖视图。
图2为本实用新型伸出状态剖视图。
图3为本实用新型使用状态(伸出)示意图。
图4为本实用新型使用状态(收缩)示意图。
具体实施方式
