Description

自来水笔的防干笔尖笔帽
技术领域:
本实用新型属于书写工具领域,具体是指自来水笔的防干笔尖笔帽。
背景技术:
自来水笔是主要的书写工具,因其便携、书写流利等优点广受欢迎,但是这种笔在停用一段时间再用时常常发生因笔尖水分蒸发而干笔尖不下水的现象,造成许多不便,究其原因主要是这种笔在笔帽套到笔杆上后笔尖周边存有较大的空隙,这种空隙里的空气会不停地掠夺笔尖上不多的水分,使笔尖逐渐变干,同时笔帽和笔杆的套合也会因密闭不够而使笔帽内外的空气互流加速带走更多的水分最终导致笔尖干掉不再下水,这种现象需要消除。
发明内容:
本实用新型目的便是提供一种笔帽的新的技术方案,它可以有效地解决上述问题。
本技术方案内容如下:它包含笔帽,所述笔帽内在顶端固接有向下的呈圆筒状且圆筒上半截筒壁上含多个气孔的胶质笔尖套。
本技术方案的有益效果是笔尖套可以在笔帽套合到笔杆上后严密的包裹住笔尖,有效地阻止了笔尖水分向周边空隙的空气蒸发,使再次书写时笔尖不会出现不下水的现象了。
附图说明:
图1为本设计举例的笔尖套。
图2为本设计举例的笔尖套安装就位后的笔帽。
图3为本设计举例的笔尖套的功效视图。各图中,1为气孔,2为笔尖套,3为笔帽,4为笔尖,5为笔杆。
具体实施方式:
选择一种较耐老化的软质胶料模具成形如图1状成笔尖套2,最好选用硅胶,形状为近似有底的筒状,弹性恢复力应较高,在上1/2部分的筒壁上加工出多个气孔1,通过粘合剂或紧配合的形式将笔尖套2固定于笔帽3的内里顶端,如图2所示,笔尖套的直径应略小于笔帽内径,高度应在笔帽内里高的约2/3左右,使用时当笔帽3套合到笔杆5上后,笔尖4会套进笔尖套2的中空筒内,笔尖套的下端面及部分靠下的筒壁会在套入笔尖的顶触下内收到筒内中空的空间里,且对笔尖部分因自身的材质特性自然的形成紧缩包裹效果,筒内的空气会在受压力作用下通过气孔1排出而不会影响笔尖的顶入,整个笔尖部分则会处于被极小的空间包裹密封住的状态,不会再有空气的内外流动而带走水分,可有效的防止笔尖变干,达到时时处于流利书写的待写状态。笔尖套2的形式也可以有其它选择,比如向下敞口形等,由于笔尖的具体形状有大笔尖、小笔尖,还有针管状笔尖,其它形式的笔尖套适应笔尖的不同形状的能力都欠理想,而本举例的有底筒形笔尖套则对各种自来水笔尖皆有较理想的密封防干效果。
