Abstract

一种胀头螺钉,由胀头、螺杆及尾槽组成,其特征是在螺钉头上有数个槽,可以缩紧和胀开;在螺钉头端头上有一定的锥度,使其能方便地进入安装孔并在通过安装孔后胀开;在螺杆的端头有供使用工具把持的尾槽,所述的尾槽为四方形、六方形、十字形沉槽,或多边形凸起,以便用扳手或十字螺丝刀把持;同时螺杆上旋紧螺母,实现方便的单边紧固操作。

Description

胀头螺钉
技术领域
本实用新型涉及机械领域,是一种新型的机械紧固装置。 
背景技术
原有的螺钉与螺母紧固时螺钉与螺母需要在两端分别把持或旋紧,操作不方便;使用胀头螺钉可以实现方便的单边紧固操作,是一种新型的紧固装置。 
实用新型内容
本实用新型提供了一种新型的螺钉紧固方式,可实现单边紧固操作。 
本实用新型采用的技术方案:一种胀头螺钉,由胀头、螺杆及尾槽组成,其特征是在螺钉头上有数个槽,可以缩紧和胀开;在螺钉头端头上有一定的锥度,使其能方便地进入安装孔并在通过安装孔后胀开;在螺杆的端头有供使用工具把持的尾槽。所述的尾槽为四方形、六方形、十字形沉槽,或多边形凸起,以便用扳手或十字螺丝刀把持;同时螺杆上旋紧螺母,实现方便的单边紧固操作。还可以将该螺钉的螺杆部分做成光轴,作为能单边插入的销轴使用。 
本实用新型可以实现单边紧固操作。 
附图说明
图1是带尾槽的胀头螺钉结构图; 
图2是带四方形凸起的胀头螺钉结构图; 
图3是旋紧螺母的胀头螺钉安装状态图。 
具体实施方式
参见图1-2,一种胀头螺钉,由胀头1、螺杆2及尾槽3组成,在螺钉头上有数个槽,可以在螺钉进入安装孔时缩紧,通过安装孔后自动胀开,挡在安装孔出口端面上;在螺钉头端头上有一定的锥度,可以方便螺钉进入安装孔;在螺杆2 的端头有尾槽3,所述的尾槽为四方形、六方形、十字形沉槽,或多边形凸起,以便用扳手或十字螺丝刀把持;同时旋紧螺母,实现方便的单边紧固操作。如图3所示,为使胀头螺钉方便地进入安装孔,可以将螺母旋到螺杆2的端头,再敲入安装孔。 
还可以将该螺钉的螺杆2做成光轴,作为能单边插入的销轴使用。
