摘　　要：针对目前电气化铁路接触网系统用防松螺母普遍采用的主副螺母结构型式不能满足小空间使用要求的情况,依据螺纹防松原理,设计一种适用于小空间使用的单螺母防松结构,该结构具有良好的防松效果。With regard to the situation that the main and auxiliary nut structures adopted currently on the OCS of electrified railway are not able to meet the requirements of small space,a single nut anti-loosening structure adaptable to small space is designed according to the thread anti-loosening principle.This structure has a better anti-loosening effect.
