Description

一种不倒翁笔
技术领域
本实用新型设计一种不倒翁笔,属于学习用品技术领域。
背景技术
生活中,我们常常会不小心将笔掉落到地上,笔尖遭到损坏。尤其是新笔,自然心痛不已,然而目前还没有一款书写笔可以做到掉到地面上,保证不损坏笔尖。
发明内容
本实用新型公开了一种不倒翁笔,可以克服现有的书写用笔,一旦掉到地面上,容易损坏笔尖的弊端。本实用新型设计的笔,采用不倒翁式原理,利用笔管内的滚珠,实现了笔的重心的灵活转换,掉到地面时笔尖朝上,这样既可以有效地保护笔尖不受损坏,又能够使人们在写字时更稳,更便捷。
一种不倒翁笔,包括笔尖、笔芯和笔杆,其特征在于:笔杆尾部直径大于笔杆直径呈圆肚状,在笔杆尾部设置封闭区间,在所述的封闭区间内添加重物。
所述的重物为滚珠或铁块。
本实用新型利用重心原理可有效防护笔尖落地受损,同时方便使用。
附图说明
图1为本实用新型结构示意图。
1、笔尖,2、笔杆,3、笔杆尾部,4、封闭区间,5、重物。
具体实施方式
以下结合附图和实施例对本实用新型加以详细说明。
一种不倒翁笔,如图1所示,包括笔尖1、笔杆2,笔杆尾部3的直径大于笔杆2的直径呈圆肚状,在笔杆尾部3设置封闭区间4,在所述的封闭区间4内添加重物5。本实施例所述的重物为滚珠,也可以添加质量较重的钢块、铁块等。
当不倒翁笔掉到地面时,由于滚珠的重力,使得不倒翁笔的重心在笔杆末端,此时笔尖朝上,由此保证笔尖不受损伤。
