Abstract

螺旋形圆珠笔芯,涉及文具用品,为了延长圆珠笔芯的使用寿命,把圆珠笔芯储存油墨用的塑料管螺旋形弯曲,笔芯内可以灌注更多的油墨量,延长了笔芯适用时间,减少浪费,本实用新型的技术方案,同样可以在一次性水笔芯上实施。

Description

螺旋形圆珠笔芯
技术领域
本实用新型涉及文具用品,尤其是一种螺旋形圆珠笔芯。
背景技术
目前,书写用的圆珠笔芯,原来在设计时,笔芯内的油墨消耗与笔头的使用寿命同步,当笔芯内的油墨用完时,笔头内滚珠逐步磨损导致笔头不能再用,整支笔芯也随之废弃,但随着材料科学的发展,圆珠笔笔头的使用寿命大大提高,当笔芯内油墨耗尽时,笔头还可以继续使用,遗弃整支笔芯成了一种浪费。
发明内容
为了延长笔芯的使用寿命,减少浪费,本实用新型提供了螺旋形圆珠笔芯。
本实用新型的技术方案:螺旋形圆珠笔芯,把圆珠笔芯储存油墨用的塑料管螺旋形弯曲,其外形如同弹簧。这样整个笔芯的长度随之增加,可以在笔芯内灌注更多的油墨。同理,本实用新型的技术方案也适用于一次性水笔芯,也即上面所述的圆珠笔芯储存油墨用的塑料管还包括一次性水笔芯储存墨水用的塑料管。
有益效果:由于圆珠笔芯储存油墨用的塑料管螺旋形弯曲,笔芯内可以储存更多的油墨,延长了笔芯的使用寿命,减少了浪费。
附图说明
下面结合附图对本实用新型作进一步说明。
图1是本实用新型的一种外形图。
在图中:1.笔头,2.螺旋形塑料管。
具体实施方式
在图1中,把圆珠笔芯储存油墨用的塑料管螺旋形弯曲,外形弹簧状,成为螺旋形塑料管(2),螺旋形塑料管(2)的一端与圆珠笔芯的笔头(1)插入连接。
本实用新型的实施方式,也可以在一次性水笔芯上实施,也即储存水笔芯墨水用的塑料管螺旋形弯曲后,可以增加水笔芯的墨水储量,延长其使用寿命。

Claims (2)

1.螺旋形圆珠笔芯,其特征是:圆珠笔芯储存油墨用的塑料管螺旋形弯曲,呈弹簧形状。
2.根据权利要求1所述的螺旋形圆珠笔芯,其特征是:所述的圆珠笔芯储存油墨用的塑料管还包括一次性水笔芯储存墨水用的塑料管。
