Abstract

一种带有笔帽的笔,在笔帽的内部设有若干膛线,在笔杆头部和尾部与笔帽内膛线相对应的位置设有凹陷或凸起,通过笔帽内的膛线和笔杆上的凹陷或凸起实现笔和笔帽的稳固结合,轻轻旋转不多的角度,就可以实现笔的打开或闭合。本实用新型结构简单,结合牢固,使用方便的特点。

Description

技术领域
本实用新型涉及一种笔。 
背景技术
现有的带笔帽的笔使用时将笔帽取下后直接将笔帽扔在一旁或者由笔帽与笔杆尾部卡接配合来实现笔帽与笔杆之间的固定配合,直接扔在一旁则容易丢失笔帽,而通过卡接配合将笔帽固定在笔杆上的形式也存在缺陷,由于每次使用笔都需要将笔帽从笔头部分取下卡接到笔杆尾部,经常使用就容易使得笔帽与笔杆之间的卡接配合磨损失效,并且这种卡接配合本身还存在配合不牢固的缺陷。 
另一种如专利号为200920192661.3的专利公开的笔为了达到笔帽牢固地固定在笔杆尾部或者笔头上的目的,在笔帽上设有内螺纹,笔杆靠近笔头的位置和笔杆笔尾的位置设有与笔帽上的内螺纹相配合的外螺纹,通过笔帽上的内螺纹和笔杆上的外螺纹配合使笔帽牢固的固定在笔头或笔尾上。但是每次打开笔的时候,都不可避免地旋转笔帽很多圈,很不方便。 
发明内容
本实用新型所要解决的技术问题是笔和笔帽之间牢固结合和笔使用不方便的问题 。 
为了解决上述技术问题,本实用新型提供一种结构简单、结合牢固、使用方便的笔,其具有笔杆和笔帽,其中笔帽内设有若干膛线,在笔杆靠近笔头与笔帽内膛线阳线相对应的位置上设有一定程度的凹陷,其凹陷深度等于或略大于笔帽内膛线上阳线凸起的高度;笔帽内膛线阴线相对应的位置上设有一定程度的凸起,其凸起的高度等于或略大于笔帽内膛线上阴线凹陷的深度;使得笔帽盖在笔杆头部上时,笔帽内部的膛线能够完美地沿着笔杆头部上相对应的凹陷与凸起旋转覆盖笔头和笔杆头部,并稳固的固定在笔杆上。 
在笔杆尾部设有与笔杆头部完全一致的凹陷与凸起,使得笔帽能够旋转固定在笔杆尾部上。 
优选的是,笔帽内部设有一层金属材料,膛线设置在金属材料上。 
优选的是,笔杆尾部末端设有一个过渡凸块,用于避免凹陷过渡磨损。 
如此,笔帽通过笔帽内的膛线与笔杆上的凹陷与凸起实现了笔帽与笔杆稳固地结合,而且只需旋转不多的角度就可以实现笔的打开和闭合,同时结构简单,使用方便;而且笔杆上的凹陷与凸起也起到了很好的装饰作用,使笔更加地美观。 
附图说明
图1为本实用新型的一优选实施例的笔帽的结构示意图。 
图2为本实用新型的一优选实施例的笔杆的结构示意图。 
图中:1、笔杆;2、笔帽;3、笔帽内的膛线;4、笔杆上的凹陷与凸起。 
具体实施方式
如图所示,1为笔杆,2为笔帽,在笔帽2的内部设有4条膛线,在笔杆1上与笔帽2内膛线3相对应的位置上设有相应的凹陷或凸起4。 
打开笔时,旋转笔帽2,只需要旋转半圈就可以把笔帽2从笔杆1头部上旋下;然后把笔帽2放置在笔杆尾部旋转半圈即可把笔帽2牢固地固定在笔杆1尾部。 
关闭笔时,旋转笔帽2 ,只需要旋转半圈就可以把笔帽2从笔杆1尾部上旋下;然后把笔帽2放置在笔杆头部旋转半圈即可把笔帽2牢固地固定在笔杆1头部。 
这样,打开和关闭笔都很方便,并且可靠。
