Abstract

一种自攻分段螺牙连接螺钉,它包括螺钉头和螺杆,其特征在于螺杆是由螺杆前部和螺杆后部两部分组成,螺杆前部和螺杆后部采用不同的螺牙,螺杆前部设有钻头。本实用新型的自攻分段螺牙连接螺钉,由于在螺杆前部设有钻头,螺杆前部和螺杆后部采用不同的螺牙,可直接在构件上钻孔连接,尤其适合两种不同材质的构件的连接,具有结构简单使用方便的特点。

Description

自攻分段螺牙连接螺钉
技术领域
本实用新型涉及连接件,具体是一种适用于直接在不同材质构件上钻孔连接的自攻分段螺牙连接螺钉。
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分段螺牙连接螺钉。
本实用新型的目的是通过如下技术方案解决的:一种自攻分段螺牙连接螺钉,它包括螺钉头和螺杆,其特征在于螺杆是由螺杆前部和螺杆后部两部分组成,螺杆前部和螺杆后部采用不同的螺牙,螺杆前部设有钻头。
本实用新型的自攻分段螺牙连接螺钉,由于在螺杆前部设有钻头,螺杆前部和螺杆后部采用不同的螺牙,可直接在构件上钻孔连接,尤其适合两种不同材质的构件的连接,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分段螺牙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,一种自攻分段螺牙连接螺钉,它包括螺钉头1和螺杆,其特征在于螺杆是由螺杆前部2和螺杆后部3两部分组成,螺杆前部2和螺杆后部3采用不同的螺牙,螺杆前设有钻头4。
