Description

不可拆卸式防盗螺母
技术领域
本实用新型涉及一种不可拆卸的防盗螺母，适用于永久固定实施的紧固件防盗，属于机械领域。
技术背景
目前，公知的防盗螺母形式很多，防盗效果较好的往往加工工艺复杂或组合件较多，以致成本较大或安装复杂；因此，对于桥梁、铁塔、公路护栏、铁路道轨等永久固定实施，人们迫切希望有一种安装方便、成本低的防盗螺母。
发明内容
为了实现安装方便、成本低的目的，本实用新型提供了一种不可拆卸的防盗螺母，
为了实现上述目的，本实用新型的技术方案是螺母本体1的内圈设有内螺纹2和凹槽4，凹槽4内置滚珠5，螺母本体1外部设置成圆台形或球台形，螺母本体1外缘设置有若干个边缘齿3。
本实用新型的有益效果是：该防盗螺母不仅加工工艺简单，现场安装方便，而且防松、防盗效果明显。
附图说明
图1是本实用新型的主视图。
图2是本实用新型的左视图。
图3是本实用新型与普通螺栓配套使用状态示意图。
附图中，1螺母本体、2螺母内螺纹、3边缘齿、4凹槽、5滚珠、6螺栓、7普通螺母。
具体实施方式
参照附图3，本实用新型使用时在普通螺母7的外侧加装此防盗螺母，其螺母本体1外部的球台形或圆台形斜面和锲形槽4内设置的钢质滚珠5(事先粘在槽内)起防盗作用，斜面上边缘齿3配专用扳手起紧固作用。该防盗螺母紧固后，偷盗者根本无法卸下，从而达到放松防盗效果。
