Description

大口径自动芯铅笔
[技术领域] 本发明属于自动铅笔技术领域， 具体涉及一种大口径自动芯铅笔。 [背景技术] 传统木制铅笔为一次性消耗使用， 国标总长 176mm， 手握铅笔部分为 88mm， 加上削尖露头部分为 15匪， 能使用部分仅为 73至 80匪， 可利用价值不足 50%。 其余的部分则造成了不必要的浪费。 因此自动铅笔如今被广泛的应用。 但是， 如今使用的自动铅笔生产成本高， 零件过多、 空间不足、 无法变换 笔芯口径。 针对上述的缺陷， 国内申请 CN931015502 、 CN201872449U 、 CN201833701U都公开了一种笔杆内置螺纹、 旋转笔芯来实现笔芯伸縮的自动铅 笔。 但是其从构造上来看， 这些自动铅笔都无法很好使用粗铅芯和进行笔芯更 换， 更不用说用于双头铅笔及双头铅笔笔芯的更换了。 传统自动铅笔结构过于 复杂， 成本过高， 在狭小空间主体无法使用木质结构铅笔和采纳的大口径标准 芯， 而塑制自动笔采用细铅芯又容易折断， 因此替代面有限。 无法从根源上解 决传统木质铅笔一次性使用从而对森林资源造成的破坏和浪费。
[发明内容] 本发明目的在于： 针对上述存在的问题， 提供一种能使用粗笔芯且换芯容 易， 结构简单合理的大口径自动芯铅笔结构。
为实现上述目的设计一种大口径自动芯铅笔， 包括笔芯 1、空芯杆 4和尾装 饰 7， 笔芯 1设置于空芯杆 4内部， 空芯杆 4尾部一端连接尾装饰 7， 其特征在 于所述的空芯杆 4内壁上设有内丝牙， 笔芯尾部一端连接外丝牙短塑管 6， 笔芯 顶部一端伸出旋转头 2， 外丝牙短塑管 6与空芯杆 4内壁上的内丝牙相配合，旋 转头 2通过连接装置 3连接空芯杆 4， 所述的笔芯 1形状为非圆柱形。
本发明还包括另一种大口径自动芯铅笔， 包括笔芯、 空芯杆和尾装饰， 笔 芯设置于空芯杆内部， 空芯杆尾部一端连接尾装饰， 其特征在于所述的空芯杆 内壁上设有内丝牙， 旋转头通过连接装置连接空芯杆， 所述的笔芯外侧设有与 空芯杆内壁上内丝牙相配合的外丝牙， 笔芯顶部一端伸出旋转头， 笔芯形状为 非圆柱形。
上述的笔芯形状为三角形或四方形或椭圆形或其他带有棱角的形状， 所述 的笔芯可以替换为树脂笔芯或中性笔芯或石墨笔芯或彩色芯或蜡笔或粉笔或固 体胶或橡皮芯或眉笔芯或口红芯。
上述的空芯杆内壁上设有内丝牙长塑管。
上述的外丝牙短塑管内置三个不同口径的笔芯插口。
本发明还包括一种大口径双头自动芯铅笔， 包括第一笔芯 la、 第二笔芯 lb 和空芯杆 4， 第一笔芯 la和第二笔芯 lb设置于空芯杆 4内部， 其特征在于所述 的空芯杆 4内壁上设有内丝牙， 空芯杆 4左部一端通过第一连接装置 3a连接第 一旋转头 2a， 空芯杆 4右部一端通过第二连接装置 3b连接第二旋转头 2b， 第 一笔芯 la左部一端伸出第一转动旋转头 2a， 第一笔芯 la右部一端连接第一外 丝牙短塑管 6a， 第一外丝牙短塑管 6a与空芯杆 4内壁上的内丝牙相配合， 第二 笔芯 lb右部一端伸出第二转动旋转头 2b， 第二笔芯 lb左部一端连接第二外丝 牙短塑管 6b， 第二外丝牙短塑管 6b与空芯杆 4内壁上的内丝牙相配合， 所述的 第一笔芯 la和第二笔芯 lb形状为非圆柱形。

上述的第一笔芯和第二笔芯形状为三角形或四方形或椭圆形或其他带有棱 角的形状， 所述的第一笔芯或第二笔芯均可以替换为树脂笔芯或中性笔芯或石 墨笔芯或彩色芯或蜡笔或粉笔或固体胶或橡皮芯或眉笔芯或口红芯。
上述的空芯杆内壁上设有内丝牙长塑管。
上述的第一外丝牙短塑管和第二外丝牙短塑管内各设有三个不同口径的笔 芯插口。
本发明主体仍可采用消费者习惯使用的木制结构 (手感好)，但在窄小空间却 增加了少量精细零部件， 通过巧妙的相互配合， 因而极大的提升了铅笔的书写 使用功能， 既不消耗木制笔杆， 且又能将整支笔芯几乎书写到消耗殆尽 为止。 并且， 本发明可变换多种笔芯包括树脂笔芯、 石墨笔芯以及彩色芯、 蜡笔、 粉笔等， 亦可在较大范围内轻松变换笔芯口径,在实践的真正意义上克服 了传统自动铅笔在窄小空间普遍使用超细树脂笔芯的历史。
