Abstract

本实用新型公开了一种防盗螺母属于紧固或固定构件或机器零件用的器件,特别是防止螺栓,螺母,或销损伤的措施。一种防盗螺母,其特征是:由螺母和垫圈组成,所述的螺母底面有放射状均匀排列的棘齿,所述的垫圈的上表面有与螺母底面的棘齿形状相同方向相反的棘齿,垫圈上有至少3个固定孔。本实用新型的有益效果是使用本防盗螺母时,首先用落定将垫圈固定在固定设施的螺杆周围,再装上螺母拧紧,在需要拧紧螺母时螺母和垫圈的棘齿处于倾斜面相交可以拧紧,当不法分子企图盗窃螺母时需要反向拧动螺母,此时螺母与垫圈的棘齿的垂直面相对,无法拧动从而可以防止被盗窃。本实用新型结构简单、使用方便、防盗效果好。

Description

防盗螺母
技术领域
本实用新型属于紧固或固定构件或机器零件用的器件,特别是防止螺栓,螺母,或销损伤的措施。
背景技术
有些固定设施采用螺母与底座固定,这些螺母经常被人盗窃造成公共财产的损失,甚至造成危险的隐患,现在也有些防止螺母被盗窃的设施,都存在结构较复杂。
实用新型内容
本实用新型的目的是提供一种防盗螺母,该防盗螺母结构简单,防盗效果好。
本实用新型解决其技术问题所采用的技术方案是:一种防盗螺母,其特征是:由螺母和垫圈组成,所述的螺母底面有放射状均匀排列的棘齿,所述的垫圈的上表面有与螺母底面的棘齿形状相同方向相反的棘齿,垫圈上有至少3个固定孔。
本实用新型的有益效果是使用本防盗螺母时,首先用落定将垫圈固定在固定设施的螺杆周围,再装上螺母拧紧,在需要拧紧螺母时螺母和垫圈的棘齿处于倾斜面相交可以拧紧,当不法分子企图盗窃螺母时需要反向拧动螺母,此时螺母与垫圈的棘齿的垂直面相对,无法拧动从而可以防止被盗窃。本实用新型结构简单、使用方便、防盗效果好。
附图说明
附图1为图2中螺母的仰视图,
图2为为本实用新型的结构示意图,
图3为图2中垫圈的俯视图。
图中,1.螺母,2.螺母棘齿,3.垫圈棘齿,4.垫圈,5.固定孔。
具体实施方式
本实用新型的具体实施方式是,如图所示:
实施例1,一种防盗螺母,其特征是:由螺母1和垫圈4组成,所述的螺母底面有放射状均匀排列的螺母棘齿2,所述的垫圈的上表面有与螺母底面的棘齿形状相同方向相反的垫圈棘齿3,垫圈上有至少3个固定孔5。
