Description

抗干保珠中性笔
本实用新型涉及一种中性笔。
现有中性笔用量很大,其不足之处是笔芯易干结、笔尖易落珠。为防止干结,常采用笔芯与笔杆分开塑封包装,一旦拆掉塑封,短时间内就会干结,难以继续使用。
本实用新型的目的就是克服上述现有技术不足,提供一种抗干结、不易落珠的抗干保珠中性笔。
本实用新型包括有笔杆、笔项、笔芯、钢头、磁环、芯簧、微簧、活动珠和球珠。笔杆后部设有转轮、揿轮、揿动钮和顶帽及笔夹。用于安装钢头和芯簧的笔芯前段较细,芯簧设在笔芯前段插座外,磁环卡装在芯簧与笔项之间。钢头后端插入笔芯前端,笔芯内部在靠近前端处具有一个缩口,缩口处装有活动珠。钢头前端设有球珠,钢头内设有微簧。书写时,球珠压缩微簧,空气对流带出笔芯内的墨水,不书写时,微簧伸张顶住球珠,将空气阻断,笔芯内的墨水不易干结,活动珠可防止钢头内的墨水倒流回笔芯。球珠、钢头、微簧、笔项均采用导磁材料制成,磁环可对钢头及球珠产生吸引力,因此不易落珠,延长了球珠的书写寿命。
本实用新型中性笔不易干结,不易落珠,使用寿命长。给使用者带来了极大的方便。而且,笔芯容量可增大,增加了书写量,既经济又耐用。
下面结合附图作进一步叙述:
附图为本实用新型结构示意图。
图中:1、活动珠,2、球珠,3、钢头,4、微簧,5、芯簧,6、磁环,7、笔项,8、笔芯,9、笔杆。
钢头3可采用半针管型或子弹头型,如采用半针管型钢头,则相应的微簧4采用探针型。如采用子弹头型钢头,则相应的微簧4采用无探针型。
笔芯8的尺寸规格可与现有碳素笔笔芯或粗芯圆珠笔笔芯的规格相同,使产品的通用性更好。
