Abstract

本实用新型公开了一种四角自挤螺栓,包括螺栓头和螺杆,所述螺杆设有外螺纹,所述螺杆的横截面为四角呈弧形的四边形。该螺栓结构简单,装配效率高。

Description

四角自挤螺栓
技术领域
本实用新型涉及一种四角自挤螺栓。
背景技术
螺栓为日常生活中不可或缺的工业必需品,在工业上也负有重要的任务,普通螺栓需要在装配部件钻出底孔后在在底孔内制出内螺纹,再与装配部件紧固,工序繁多,时间和人力成本较大。
实用新型内容
鉴于背景技术存在的不足,本实用新型所要解决的技术问题是提供一种结构简单、成本较低且装配效率高的自挤螺栓。
本实用新型是采取如下技术方案来完成的:四角自挤螺栓,包括螺栓头和螺杆,所述螺杆设有外螺纹,所述螺杆的横截面为四角呈弧形的四边形。
本实用新型中,该四角自挤螺栓结构简单,在使用时可直接在装配零部件上自挤压出与螺杆相匹配的内螺纹,并与之紧固连接装配零部件。并且,螺栓横截面为四角呈弧形的四边形的结构使得自挤连接时受力均匀,大大提高了生产装配效率。
附图说明
本实用新型有如下附图:
图1为实用新型提供的四角自挤螺栓的结构平面示意图。
图2为图1中的四角自挤螺栓的A-A剖视示意图。
具体实施方式
附图表示了本实用新型的技术方案及其实施例,下面再结合附图进一步描述其实施例的各有关细节及其工作原理。
参照图1、图2所示,本实用新型提供的四角自挤螺栓,包括螺栓头1和螺杆2,所述螺杆2设有外螺纹3,所述螺杆2的横截面4为四角呈弧形的四边形。所述四边形的大径为D,所述四角弧形5的长度为1.6×D。
该四角自挤螺栓在使用时可直接在装配零部件上自挤压出与螺杆相匹配的内螺纹,并与之紧固连接装配零部件,其横截面4为四角呈弧形的四边形使得自挤连接时受力均匀,大大提高了生产装配效率。
