Description

木螺钉
本实用新型属于一种建筑用特殊钉，尤其涉及一种木螺钉。
目前建筑行业通常使用的木螺钉包括自攻螺钉、墙板钉和纤维板钉等类型。这些螺钉共同的一个特点是，螺杆部分设计成外表面具有螺旋槽的圆柱结合锥面螺旋槽的圆锥两段，在人工或使用电动工具拧入木质制件时，容易使木质制件的表面凿开，并随着螺旋槽的逐渐推进而进入木制件。这些现有的木螺钉在遇到硬度特别大的木制件时，需要费较大的力量拧入，但较大的力又容易使木质制件表面受损，而现在使用高密度板材的情况非常普遍，相应的对这种木螺钉的需求也越来越大，随之提出了如何减轻用力，避免损伤制件的问题。
本实用新型的目的是，解决上述需要靠增大拧紧力来钉入木质制件的问题，通过改进螺杆和尾锥外表面螺纹以及尾锥螺旋槽的结构，不仅降低拧入扭矩，而且降低了操作过程中对木质制件的损伤。采用本实用新型的螺钉，可以提高工效，达到事半功倍的效果。
本实用新型是这样实现的：包括头部、螺杆和尾锥三部分，螺杆外表面为切有螺旋槽的圆柱，尾锥为外表面形成螺旋槽的锥体，木螺钉的螺杆和尾锥上的螺纹为锯齿形状。
下面，参照附图，对于熟悉本技术领域的人员而言，从对本实用新型的详细描述中，本实用新型的上述和其他目的、特征和优点将显而易见。
图1给出本实用新型木螺钉一个较佳实施例的结构示意图；
图2给出图1所示实施例的A-A视图。
请参照图1所示，该木螺钉包括头部1、螺杆2和尾锥3三部分组成。螺杆1为外表面具有切螺旋槽的圆柱，尾锥3为外表面同样采用螺旋槽结构的圆锥。螺杆1的螺纹可以设计成规则或不规则的锯齿缺口，使切削过程更加省力，拧入时更加轻快，特别适用于电动工具操作。在尾锥3设有多条相互平行的扩孔刃4，扩孔刃4与尾锥3外表面上平行的螺纹相交叉，扩孔刃4与螺杆1的中心线成一定角度θ，扩孔刃4的形状包括锥形，锯齿形，在拧入过程中木质(尤其是硬质木)制件自行扩孔，使木体受到的挤压力大大减小。
以上诸实施例仅供说明本实用新型之用，而非对本实用新型的限制，有关技术领域的技术人员，在不脱离本实用新型的精神和范围的情况下，还可以作出各种变换或变化，因此所有等同的技术方案也应该属于本实用新型的范畴应由各权利要求限定。
