Abstract

一种单旋向螺母,由外往内依次由螺母外套4、 前后两个密封挡圈5和带斜槽的螺母体2组成,前后 密封挡圈5将滚动子1卡在螺母体2的斜槽内,该实 用新型的优点在于设计巧妙,操作方便,可靠性强,特 别适用于输变电线路的铁塔设施上。

Description

本实用新型涉及一种螺母,尤其是一种单旋向螺母。
近年来,我国许多地方连续发生设置于野外无人看管的重要设施被盗,特别是输变电线路的铁塔设施的被盗,其主要客观原因是,这些设施上的紧固螺栓均为国家标准的六角头,使用一般的通用工具如活搬手等均能轻而易举的将螺母松开拆下。
本实用新型的目的是提供一种用任何工具也不能松开拆下的单旋向螺母。
本实用新型的目的可以通过以下措施来实现:本实用新型所述的单旋向螺母,由外往内依次由螺母外套、前后两个密封挡圈和带斜槽的螺母体组成,前后密封挡圈将滚动子卡在螺母体的斜槽内。
本实用新型的优点在于:设计巧妙,操作方便,可靠性强。
下面结合附图详细介绍本实用新型的结构和工作原理。
图1为本实用新型的俯视图;
图2为本实用新型的左视图(剖视图);
图3为螺母体和滚动子的位置关系图。
本实用新型所述的单旋向螺母,由外往内依次由螺母外套4、前后两个密封挡圈5和带斜槽的螺母体2组成,前后密封挡圈5将滚动子1卡在螺母体2的斜槽内。
当顺时针旋转螺母外套4时,带动滚动子1转动,通过滚动子1的转动,将力矩传至螺母体2,使之与螺母外套4一起转动,直至将螺母拧紧。如果逆时针旋转螺母外套4,则由于不可逆结构的作用,螺母外套4只能空转,螺母体2则纹丝不动。
本实用新型单旋向螺母使用一般通用工具即可操作,不需要特殊专用工具。
