Abstract

本实用新型公开了一种防松螺母。旨在提供一种结构简单、防松效果好的防松螺母。它包括有六角形的螺母,其特征是在螺母的一个端面制有大于或等于六角形外切的圆形垫,在圆形垫的端面制有沟槽。该实用新型由于在螺母使用时的接触端面制有沟槽,增加了接触表面的摩擦力,提高了防松的效果,对于放松要求低的结构可直接使用该防松螺母,对于放松要求高的结构可再加弹簧垫圈,其防松效果会更好。

Description

防松螺母
技术领域
本实用新型涉及一种紧固件,更具体地说涉及一种防松螺母。
背景技术
现有的螺母大多需要在螺母和平垫圈或零件之间安装弹性(弹簧)垫圈来防止振动而使螺母松动,这样的结构复杂,对于在振动大的机械设备上使用有时还是发生螺母松动的现象。
发明内容
本实用新型的目的是提供一种结构简单、防松效果好的防松螺母。
为了达到上述要求,所采用的技术方案是:它包括有六角形的螺母,其特征是在螺母的一个端面制有大于或等于六角形外切的圆形垫,在圆形垫的端面制有沟槽。
所述的沟槽为顺时针旋向。
根据上述方案制造的防松螺母,由于在螺母使用时的接触端面制有沟槽,增加了接触表面的摩擦力,提高了防松的效果,对于放松要求低的结构可直接使用该防松螺母,对于放松要求高的结构可再加弹簧垫圈,其防松效果会更好。
附图说明
图1是防松螺母的主视图;
图2是图1的左视图;
图3是图1的右视图。
其中:1、螺母;2、圆形垫;3、沟槽。
具体实施方式
下面结合附图和具体实施例对本实用新型作进一步的描述。
图1、图2、图3是防松螺母的结构示意图。从图中看出,它包括有六角形的螺母1,在螺母1的一个端面制有大于或等于六角形外切的圆形垫2,在圆形垫2的端面制有沟槽3,所述的沟槽3为顺时针旋向。

Claims (2)

1.防松螺母,它包括有六角形的螺母,其特征是在螺母的一个端面制有大于或等于六角形外切的圆形垫,在圆形垫的端面制有沟槽。
2.根据权利要求1所述的防松螺母,其特征是所述的沟槽为顺时针旋向。
