Abstract

一种自攻连接螺钉,它是同种材料制成的整体结构,包括螺钉头和螺杆,其特征在于螺杆前端设有钻头。本实用新型的自攻连接螺钉,由于在螺杆前端设有钻头,可直接在构件上钻孔连接,具有结构简单,使用方便的特点。

Description

自攻连接螺钉
技术领域
本实用新型涉及连接件,具体是一种适用于在连接构件上直接钻孔连接的自攻连接螺钉。
背景技术
普通的螺栓连接是先在两个构件上打孔,然后将螺栓穿入孔中,在螺栓穿出的端头用螺母连接。由于结构上的原因,上述普通的螺栓在连接大型构件时很不方便。
发明内容
本实用新型的目的是针对普通螺栓在使用上的缺陷,提出一种直接在构件上钻孔连接的自攻连接螺钉。
本实用新型的目的是通过如下技术方案解决的:一种自攻连接螺钉,它是同种材料制成的整体结构,包括螺钉头和螺杆,其特征在于螺杆前端设有钻头。
本实用新型的自攻连接螺钉,由于在螺杆前端设有钻头,可直接在构件上钻孔连接,具有结构简单使用方便的特点。
附图说明
图1为本实用新型的自攻连接螺钉的结构示意图。
具体实施方式
下面结合附图通过实施例对本实用新型作进一步说明:
如图1所示,一种自攻连接螺钉,它是同种材料制成的整体结构,包括螺钉头1和螺杆2,其特征在于螺杆2前端设有钻头3。
