Abstract

本实用新型公开了其自攻能力强,能够用于攻覆有铁皮的硬木且不易造成硬木攻裂。一种防攻破防松木地板钉,包括头部,固定在头部上的钉杆,在钉杆上设有截面呈三角形的螺纹,在所述钉杆的尾端上具有钉尾,钉尾呈锥体状,在钉尾上设有切削刀片,切削刀片呈片状,并且切削切片的宽度由内向外逐渐减小。

Description

防攻破防松木地板钉
技术领域
本实用新型属于自攻螺钉的技术领域。
背景技术
公告号为202690651U、公告日为2013年01月23日的中国实用新型专利公开了一种自钻自攻螺钉,由螺钉杆和螺钉头组成,螺钉杆包括上下两部分,上部为自攻丝、下部为钻头,在螺钉头的外表面附着有防锈层。这种结构的自钻自攻螺钉在攻硬木时易造成木头破裂,不适于攻硬木。再者,这种结构的自钻自攻螺钉在攻表面覆有铁皮的硬木,需预先钻孔,这就使得工序复杂。
发明内容
本实用新型的目的是提供一种防攻破防松木地板钉,其自攻能力强,能够用于攻覆有铁皮的硬木且不易造成硬木攻裂。
本实用新型的目的是这样实现的:一种防攻破防松木地板钉,包括头部,固定在头部上的钉杆,在钉杆上设有截面呈三角形的螺纹,在所述钉杆的尾端上具有钉尾,钉尾呈锥体状,在钉尾上设有切削刀片,切削刀片呈片状,并且切削切片的宽度由内向外逐渐减小。
在上述方案的基础上并作为上述方案的优选方案:所述螺纹与所述钉尾之间具有间距,在钉杆的侧面上位于螺纹与钉尾之间的位置设有多条呈螺旋状的凸棱。
在上述方案的基础上并作为上述方案的优选方案:所述螺纹由第一螺纹段和第二螺纹段组成,并且第一螺纹段与第二螺纹段之间具有间距。
本实用新型相比现有技术突出且有益的技术效果是:
本实用新型的防攻破防松木地板钉采用这种结构的切削刀片,其钻孔能力更强,可以攻覆有铁皮的硬木,使用时,其先攻过一层薄铁皮,然头攻破硬木,无需提前打预钻孔。
附图说明
图1是本实用新型的示意图。
具体实施方式
下面结合附图以具体实施例对本实用新型作进一步描述,参见图1;
本实施例给出了一种防攻破防松木地板钉,包括头部1,固定在头部上的钉杆2,在钉杆2上设有截面呈三角形的螺纹3,在所述钉杆的尾端上具有钉尾4,钉尾4呈锥体状,在钉尾上设有切削刀片5,如图中所示,切削刀片位于钉尾的中轴线上。切削刀片呈片状,并且切削切片的宽度由内向外逐渐减小。采用这种结构的切削刀片,其钻孔能力更强,可以攻覆有铁皮的硬木,使用时,其先攻过一层薄铁皮,然头攻破硬木,无需提前打预钻孔。
在本实施例中,所述螺纹3与所述钉尾4之间具有间距,在钉杆的侧面上位于螺纹与钉尾之间的位置设有多条呈螺旋状的凸棱7。采用这种结构,在两条凸棱之间形成排屑槽6,在防攻破防松木地板钉攻入硬木过程中所产生的木屑能够迅速地被排出,能够更加有效地保证硬木完好性。
在本实施例中,所述螺纹3由第一螺纹段31和第二螺纹段32组成,并且第一螺纹段31与第二螺纹段32之间具有间距。
上述实施例仅为本实用新型的较佳实施例,并非依此限制本实用新型的保护范围,故:凡依本实用新型的结构、形状、原理所做的等效变 化,均应涵盖于本实用新型的保护范围之内。
