The invention discloses a writing and counting dual-purpose pen, which is characterized in that a counter is arranged in the pen rod, and the counter has a counting button, a reset button and a digital display screen. The pen core used is a pen core with wings, and a cylindrical slider with a hole in the middle is also provided. The slider is inserted from the back of the pen core through a hole in the middle, and is stuck in the pen core. A circular groove is arranged on the upper part of the wing, and a curved leaf spring is arranged at the corresponding part of the pen rod relative to the slider, which is shaped like \s\. One end of the leaf spring is attached to the inner wall of the pen rod, and one end has a protrusion. A longitudinal groove is arranged at the position of the pen rod relative to the leaf spring, and a sliding button is exposed outside the pen rod through the sliding groove. By pushing the sliding button position, the end of the leaf spring can be protruded into or out of the ring groove of the slide block, thereby controlling the switch between the two functions of the writing and counting pen; the leaf spring, protrusion, longitudinal groove and sliding button are located in the front of the pen rod, that is, near the normal position of the pen holder, so as to use conveniently and improve efficiency.
【技术实现步骤摘要】
一种书写计数两用笔
本专利技术属于文具用品笔的
,涉及一种书写计数两用笔。
技术介绍
目前,笔作为一种书写工具,已经广泛的渗透到人们的生活中。普通的笔,无论是铅笔、圆珠笔或者钢笔,都只具有书写功能,功能比较单一。随着科学技术的发展,有专利技术人将计数器应用到笔上,专利技术了计数笔,实现了笔的计数功能,但却失去了原有笔的正常书写功能,更不要说进行计数功能和书写功能间的切换。随着研究的深入,又有人重新设计,专利技术了书写计数两用笔,实现了笔的书写与计数的双种功能,并且二者可以根据需要自由切换,给使用带来了很多便利,如公开号CN205768204U所述的一种书写计数两用笔就是其中之一。公开号CN205768204U所述的技术特征是:一种书写计数两用笔由笔帽、笔头、笔杆组成,笔杆内设有计数器,计数器计数按钮、复位按钮和数字显示屏,笔杆上相应部位开有数字显示屏窗口,用以显示数字显示屏计数变化;笔芯帽为圆柱体,一端与笔芯相连,另一端与计数按钮通过凸起、凹陷相互嵌套在一起;笔芯帽有环状凹沟,在笔杆内部相应部位设有曲状片簧,形状似“s”,片簧一端附着在笔杆内壁,一端具有突起;在笔杆相对片簧位置开有纵向凹槽,纵向凹槽上有滑动按钮露出在笔杆外,通过调拨滑动按钮位置,可以将片簧末端突起嵌入或退出笔芯帽环状凹沟,从而控制书写计数两用笔两种功能的切换。经过分析,我们认为公开号CN205768204U的书写计数切换开关即片簧、突起、纵向凹槽、滑动按钮、笔芯帽及其环状凹沟等位置位于笔杆后端,距离正常握笔的位置距离较远,在实施书写计数功能切换时不是非常便利,操作的动作略嫌繁琐,所以 ...
【技术保护点】
1.一种书写计数两用笔,由笔帽、笔头、笔杆组成,其特征是笔杆内设有计数器,计数器有计数按钮、复位按钮和数字显示屏,笔杆上相应部位开有数字显示屏窗口,用以显示数字显示屏计数变化;笔芯为弹跳式圆珠笔所使用的带翼部笔芯,同时另设有一个中间有孔的圆柱体滑块,滑块通过其中间的孔从笔芯后部套入,卡在笔芯翼部上方,滑块上另有一环状凹沟;在相对于滑块的笔杆内部相应部位设有曲状片簧,形状似“s”,片簧一端附着在笔杆内壁,一端具有突起,在笔杆相对片簧位置开有纵向凹槽,纵向凹槽上有滑动按钮露出在笔杆外,通过调拨滑动按钮位置,可以将片簧末端突起嵌入或退出滑块环状凹沟,从而控制书写计数两用笔两种功能的切换;片簧、突起、纵向凹槽、滑动按钮位于笔杆前部,即正常握笔位置附近;笔芯有笔芯帽,笔芯帽结构与普通圆珠笔相同,一端与笔芯相连,另一端与计数器计数按钮位置相对。
