Abstract

一种笔芯,包括用于填充墨水或者油墨的管体以及设置在管体前端的笔尖,其中,管体的形状呈螺旋状。本实用新型笔芯的优点在于:由于螺旋状管体内的空间要远大于直形状管体内的空间,因此,本实用新型笔芯上的螺旋状管体可以多填充一些墨水或者油墨,从而可以大大延长笔芯的使用时间。

Description

笔芯
技术领域:
本实用新型涉及一种书写工具的附属品,具体讲是一种用于圆珠笔中的笔芯。
背景技术:
用于圆珠笔中的笔芯通常包括一段较长的直形管体,管体的前端设有金属笔尖,直形管体内带有墨水或者油墨,这种笔芯通常都是一次性使用的,换句话说,当直形管体内的墨水或者油墨用完后,这个笔芯就要被新的笔芯替换了,所以说,笔芯使用时间的长短取决于直形管体内墨水或者油墨的容量大小。
实用新型内容:
本实用新型要解决的技术问题是,提供一种可以多填充一些墨水或者油墨,从而大大延长使用时间的笔芯。
本实用新型的技术解决方案是,提供一种具有以下结构的笔芯:包括用于填充墨水或者油墨的管体以及设置在管体前端的笔尖,其中,管体的形状呈螺旋状。
采用以上结构后,与现有技术相比,本实用新型笔芯具有以下优点:显而易见,螺旋状管体内的空间要远大于直形状管体内的空间,换句话说,螺旋状管体可以多填充一些墨水或者油墨,从而可以大大延长笔芯的使用时间。
附图说明:
图1是本实用新型笔芯的立体结构示意图;
具体实施方式:
下面结合附图和具体实施方式对本实用新型笔芯作进一步详细说明:
如图1所示,本实用新型笔芯包括用于填充墨水或者油墨的管体1以及设置在管体1前端的笔尖2,管体1的形状呈螺旋状。
