Description

一种防松螺栓
所属技术领域
本实用新型涉及一种用于紧固连接的螺栓。
背景技术
目前通常使用的标准螺栓,使用一段时间后或在运输中受到震动,螺母常出现松动现象。
发明内容
为了克服现有标准螺栓易松动的不足,本实用新型提供一种防松螺栓。
本实用新型解决其技术问题所采用的技术方案是:一种防松螺栓,包括螺杆,螺杆由正向螺纹段及反向螺纹段构成,反向螺纹段的直径小于正向螺纹段直径。
本实用新型的有益效果是结构简单,成本低,防松效果好。
附图说明
图1是实施例的剖面构造图
图中:1.螺杆;2.正向螺纹段;3.反向螺纹段。
具体实施方式
如图1所示,一种防松螺栓,包括螺杆1,螺杆1由正向螺纹段2及反向螺纹段3构成,反向螺纹段3的直径小于正向螺纹段2直径。由于设置了反向螺纹段3,在拧上标准螺母后再拧上一反向螺母,防松效果好。
