Abstract

“凹凸结构中性笔笔管及笔管头”型涉及一种中性笔笔管及笔管头,属于文具领域;笔杆采用竹制笔杆4,笔杆4端部为凸字型端部;笔管头通过模具,用塑料刻制而成;采用凹凸结构,笔管头尾部刻制成一个圆柱型凹槽1,在笔芯插入到笔管4后,将笔杆4的凸字型端部5直接插入笔管头的圆柱型凹槽1内即可进行书写;使用竹制中性笔笔杆及笔管头和凹凸结构后,可以降低塑料制中性笔笔杆及笔管头的使用量,从而减少塑料对环境的污染,而且制作工艺简单,成本低,使用方便。

Description

凹凸结构中性笔笔管及笔管头
技术领域
本实用新型涉及一种中性笔笔管及笔管头,属于文具领域。
背景技术
现在使用的中性笔笔管及笔管头,材料是以塑料制品为主,大量的使用意味着大量的浪费,回收成本较高,对环境的影响也将继续;笔管及笔管头基本通过螺纹连接固定,这种连接方式工艺比较复杂,所以我们亟待对现有中性笔进行改进。
发明内容
本实用新型的目的是提供一种可以降低制作成本,同时能够配合竹制中性笔笔管多次使用的套式笔管头。
本实用新型解决其技术问题所采用的技术方案是:一种凹凸结构中性笔笔管及笔管头,包括笔管和笔管头,其特征是笔管及笔管头之间采用凹凸结构,笔管的端部为凸字型端部,笔管头尾部为一个圆柱型凹槽,凸字型端部可以直接插入圆柱型凹槽。
本实用新型的有益效果是使用竹制中性笔笔杆及笔管头和凹凸结构后,可以降低塑料制中性笔笔杆及笔管头的使用量,从而减少塑料对环境的污染,而且制作工艺简单,成本低,使用方便。
附图说明
图1为本实用新型实施的凹凸结构中性笔笔管及笔管头的示意图。
图2为笔管头的示意图。
图中1圆柱型凹槽,2笔芯入口,3笔管头内的固定齿,4笔杆,5凸字型端部。
具体实施方式
笔杆采用竹制笔杆4,笔杆4端部为凸字型端部;笔管头通过模具,用塑料刻制而成;采用凹凸结构,笔管头尾部刻制成一个圆柱型凹槽1,在笔芯插入到笔管4后,将笔杆4的凸字型端部5直接插入笔管头的圆柱型凹槽1内即可进行书写,省去了螺纹式连接制造螺纹的麻烦,降低了工艺复杂度,同时采用竹制材料,更环保;笔管头内的固定齿3通过模具刻制,笔管头内的固定齿3用来保持笔芯在笔头内的稳定性。
