Abstract

本实用新型公开了一种重复利用的笔芯,包括油管和书写头,所述油管内充有油墨,其特征是,所述油管内油墨的顶部设有边缘光滑的橡胶塞,所述橡胶塞的顶部设有可伸缩的推拉杆,通过推拉杆推动橡胶塞前行或后退。本实用新型的笔芯可以重复利用,从而节约了资源。

Description

重复利用的笔芯
技术领域
本实用新型涉及一种学习用品,尤其是一种笔芯。
背景技术
现有的中性笔芯的油墨采用密封油进行封闭,当笔芯内的油墨使用完毕后,笔芯不能重新再利用,只能扔掉,十分浪费。
实用新型内容
本实用新型的目的是克服现有技术中的不足,提供一种重复利用的笔芯,该笔芯可以重复利用,从而节约了资源。
本实用新型解决其技术问题所采用的技术方案是:一种重复利用的笔芯,包括油管和书写头,所述油管内充有油墨,其特征是,所述油管内油墨的顶部设有边缘光滑的橡胶塞,所述橡胶塞的顶部设有可伸缩的推拉杆,通过推拉杆推动橡胶塞前行或后退。
当油管内油墨较多时,将推拉杆缩至最短,当笔芯内的油墨因使用而逐渐减少时,油墨上方的橡胶塞在负压下向前移动(必要时使用推拉杆向前推动),当油管内油墨较少时,通过推拉杆将橡胶塞拉出,向油管内注入油墨后再重新将橡胶塞放入油管内。为了便于推拉杆更容易的推拉橡胶塞,油管可以适当的设计为短粗型的。
本实用新型具有以下突出的有益效果:本实用新型的笔芯可以重复利用,从而节约了资源。
附图说明
附图1是本实用新型的结构示意图;
附图标记说明:1油管,2书写头,3橡胶塞,4推拉杆。
具体实施方式
如图1所示,一种重复利用的笔芯,包括油管1和书写头2,所述油管1内充有油墨,所述油管1内油墨的顶部设有边缘光滑的橡胶塞3,所述橡胶塞3的顶部设有可伸缩的推拉杆4;通过推拉杆4推动橡胶塞3前行或后退。
当油管内油墨较多时,将推拉杆缩至最短,当笔芯内的油墨因使用而逐渐减少时,油墨上方的橡胶塞在负压下向前移动(必要时使用推拉杆向前推动),当油管内油墨较少时,通过推拉杆将橡胶塞拉出,向油管内注入油墨后再重新将橡胶塞放入油管内。
