Abstract

本实用新型公开了一种凹面压线螺栓,包括螺栓头和螺杆,在螺栓头的上表面上设有“一”字通槽,在螺杆上设有螺旋状的螺纹,在螺杆底部端面处设有一个圆形凹面。本实用新型得到的凹面压线螺栓,其技术效果是通过螺杆底部端面设置的圆形凹面而使得压线效果佳,压住的电线不易移动。

Description

凹面压线螺栓
技术领域
本实用新型涉及一种螺栓,特别是凹面压线螺栓。 
背景技术
目前,用于压线的螺栓各色各样,其螺杆底部端面的形状大致可分为尖形,平头形,圆形;但是尖形螺栓容易毁坏线路,平头形螺栓压线力度不够,圆形螺栓则容易打滑,而且当电线过多时,这些压线螺栓都很难起到压线的作用。 
实用新型内容
本实用新型的目的是为了解决上述现有技术的不足而提供一种压线效果佳的凹面压线螺栓。 
为了实现上述目的,本实用新型所设计的凹面压线螺栓,包括螺栓头和螺杆,在螺栓头的上表面上设有“一”字通槽,在螺杆上设有螺旋状的螺纹,在螺杆底部端面处设有一个圆形凹面,上述圆形凹面的凹面口沿与螺杆底面之间为弧面过渡。 
在具体使用过程中,由于电线表皮为橡胶材料,质地较软,当螺栓的凹面碰到电线表皮层时,可以嵌入表皮层中从而达到更高的压线效果,使得电线不易移动。 
本实用新型得到的凹面压线螺栓,其技术效果是通过螺杆底部端面设置的圆形凹面而使得压线效果佳,压住的电线不易移动。 
附图说明
图1是实施例1的凹面压线螺栓的结构示意图。 
图中:螺栓头1、螺杆2、通槽3、凹面4。 
具体实施方式
下面结合附图和实施例对本实用新型进一步说明。 
实施例1: 
如图1所示,本实施例提供的凹面压线螺栓,包括螺栓头1和螺杆2,在螺栓头1的上表面上设有“一”字通槽3,在螺杆2上设有螺旋状的螺纹,在螺杆2底部端面处设有一个圆形凹面4,上述圆形凹面4的凹面口沿与螺杆2底面之间为弧面过渡。在具体使用过程中,先将该螺栓放入螺孔中,然后用螺丝刀对准“一”字型通槽3旋转拧入即可,由于电线表皮为橡胶材料,质地较软,当螺栓的凹面碰到电线表皮层时,可以嵌入表皮层中从而达到更高的压线效果,使得电线不易移动。
