具有柔性收纳罩的卷笔刀 技术领域
本发明涉及一种卷笔刀,特别涉及一种具有柔性收纳罩的卷笔刀。
背景技术
卷笔刀通常被用于削木制的铅笔及眉笔等。通常铅笔在卷笔刀的刀片旁旋转会被削下一些笔削,这些笔削会直接落到桌面或地面等弄脏环境。继而,有一种在卷笔刀外设置一层透明的罩,削下来的笔削就保留在了罩内。当笔削积累到一定量时可以将罩卸下来而将笔削倒入垃圾桶内。目前市面上的卷笔刀罩都是坚硬的塑料材质制备的,其触碰起来手感坚硬,如果将这种带有坚硬的罩的卷笔刀收纳起来,对收藏空间的形状的要求是要有足够的与罩形状相适应的空间收纳。因此,目前市面上的这种坚硬罩的卷笔刀存在触碰手感坚硬且需要对收纳空间有形状要求的技术问题。
发明内容
为了克服现有技术的不足,本发明公开了一种触碰手感柔软且便于被收纳的具有柔性收纳罩的卷笔刀。

一种具有柔性收纳罩的卷笔刀,包括卷笔刀主体部,主体部包括底座和收容在底座内的用于削铅笔的刀座,刀座上设有插入铅笔的插入孔,底座上设有基部,基部的顶部开设有至少一个与刀座的插入孔相对应的孔,卷笔刀还包括一可与底座的基部相结合或从底座的基部上拆卸的用于收纳笔削的柔性收纳部。
进一步的,柔性收纳部包括一固设部和一结合在固设部上的柔性收纳罩,该固设部可与底座的基部相结合或拆卸。
进一步的,柔性收纳罩的罩口设置有一层热熔性材料,其通过热熔技术而将该柔性收纳罩与固设部固定在一起。
进一步的,柔性收纳罩通过缝纫的方式将柔性收纳罩与固设部固定在一起。
进一步的,固设部包括第一固设部和第二固设部,第一固设部的内径略 微大于第二固设部的内径,柔性收纳罩的罩口包在第二固设部的外面,第一固设部将柔性收纳罩的罩口卡箍固定在第二固设部外部而实现将固设部与柔性收纳罩固定。
进一步的,底座的基部上设有内螺纹,固设部的外圆周设置有与底座的基部的内螺纹可以相互螺接的外螺纹,底座和固设部通过螺纹连接将底座与柔性收纳部结合或拆卸。
进一步的,底座的基部上与收纳部上分别设有卡扣结构而将底座与收纳部固定。
进一步的,底座的基部的内侧设有凸肋部,而收纳部上对应位置设有凹槽,通过凸肋部和凹槽的配合而将底座与收纳部固定。
进一步的,底座的基部的内侧设有多个凸肋,而收纳部上对应位置设有多个凹槽,通过多个凸肋和多个凹槽的配合而将底座与收纳部固定。
进一步的,基部圆周的下边缘设有至少一个可弯折的折片,折片上开设有孔,在固设部上对应的位置设置有凸起,当基部组装到固设部上时,弯折该折片而将凸起卡扣在折片的孔内,从而实现将主体部与收纳部的固定,当需要拆下时,将折片拉离凸起而使得折片脱离凸起而实现主体部与收纳部分开。
进一步的,底座还包括与基部相对应的防尘盖,防尘盖与基部通过一可折叠的部分将两者连接在一起,并且在使用时防尘盖可以从基部上打开,在使用完毕时也可以盖在并卡扣固定在基部上。
进一步的,防尘盖上的对应基部的孔的位置设置有尺寸和形状与孔相对应的凸起,在防尘盖盖在基部上时,该凸起凸伸并卡扣入顶部的孔内而将防尘盖固定地盖在基部上。

具体实施方式
下面结合附图对本发明作进一步描述:
请参阅图1,为一种具有柔性收纳罩的卷笔刀的第一实施例,其包括卷笔刀主体2和柔性收纳部3。
请参阅图2和图3,为一种具有柔性收纳罩的卷笔刀的第二实施例,其与实施例一相同的是包括卷笔刀主体部2和柔性收纳部3。
卷笔刀主体部2包括底座22和刀座26。与第一实施例不同的是,底座22除了包括基部23外,还包括与基座23相对应的防尘盖24。防尘盖24与基部23通过一可折叠的部分将两者连接在一起,并且在使用时防尘盖24可以从基部23上打开,在使用完毕时也可以盖在并卡扣固定在基部23上。
在本实施例中基部23为一设有容纳空间的环形体。该基部23包括一顶部231和具有一定厚度的一环形侧壁232从顶部231一侧向下延伸。顶部231上开设有至少一个孔2312,孔2312的大小刚好可以将要削的铅笔插入。本实施例中基部23设有两个孔2312。顶部231的一边缘处设有一个适应手指打开防尘盖的一个缺口2314。
防尘盖24上的对应孔2312的位置设置有尺寸和形状与孔2312相对应的凸起2412,在防尘盖24盖在基部23上时该凸起2412凸伸并卡扣入顶部231 的孔2312内而将防尘盖24固定地盖在基部23上。在本实施例中,侧壁232内圆周上设有内螺纹。
在本实施例中,刀座26为常规的两孔削铅笔的刀座,其固设在基部23的收纳空间内,其上设有的容纳铅笔的插入孔与基部23上的孔2312相对准。
柔性收纳部3包括一固设部31和结合在固设部31上的柔性收纳罩33。在本实施例中,固设部31为环状结构,固设部31的外圆周设置有与底座22的基部23的侧壁232的内螺纹可以相互螺接的外螺纹。
柔性收纳罩33的材质为柔性的织物材质,其用于收纳卷笔刀削下来的铅笔削,在本实施例中,柔性收纳罩的罩口设置有一层热熔性材料,其通过热熔技术而将该柔性收纳罩33与固设部31固定在一起。
当使用者需要削铅笔时,先将防尘盖24打开,根据铅笔的外圆周尺寸选择合适的刀座进行削铅笔,削下来的笔削就落入了柔性收纳罩33中。当笔削的量积攒到一定量时,将收纳部3从主体部2上旋转下来,将笔削倾倒出去后再将收纳部3旋转固定回主体部2上。另外,在放置该具有柔性收纳罩的卷笔刀时,由于柔性收纳罩可以随着收纳空间的不同而柔性地适应各种收纳空间的形状,因此非常便于被收纳。
请参阅图4和图5,在第三实施例中,也可以先将固设部31’套在柔性收纳罩33’的罩口,再将罩口翻下来而先将固设部31’包覆起来,再通过缝纫线312’将罩口缝纫起来而使得固设部31’与柔性收纳罩33’结合在一起。在这种实施例中,固设部31’与基部23’是通过过盈配合的方式将二者结合固定。
另外,请参阅图6,在第四实施例中,固设部还可以设置成两体的结构,分别为第一固设部314和第二固设部315,第一固设部的内径略微大于第二固设部的内径,装配时,将柔性收纳罩的罩口包在第二固设部315的外面,再用第一固设部314将柔性收纳罩的罩口卡箍固定在第二固设部外部而实现将固设部与柔性收纳罩固定。最后在采用过盈配合的方式将固设部与基部结合固定。
再请参阅图7,在第五实施例中,基部23”侧壁的下边缘内部设有一条环形的凸肋部232”,固设部31”的对应位置上开设有一条环形凹槽312”。当主体部2”需要与收纳部3”结合时是通过基部23”上的凸肋部232”卡嵌入固设 部31”的环形凹槽312”内而实现的。
再请参阅图8,第六实施例中凸肋部232”可以是间隔的几段凸肋232”’,而环形凹槽312”可以是凹槽312”。
还请参阅图9,第七实施例中基部23圆周的下边缘设有至少一个可弯折的折片231,折片231上开设有孔232,在固设部31上对应的位置设置有凸起314,当基部组装到固设部31上时,弯折该折片231而将凸起314卡扣在折片231的孔232内,从而实现将主体部与收纳部的固定,当需要拆下时,将折片拉离凸起而使得折片脱离凸起而实现主体部与收纳部分开。在本实施例中,折片和凸起的数量均为2个。
本发明的技术范围不仅仅局限于上述说明中的内容,本领域技术人员可以在不脱离本发明技术思想的前提下,对上述实施例进行多种变形和修改,而这些变形和修改均应当属于本发明的范围内。
