Abstract

本实用新型涉及到一种装有尼龙密封圈及棘齿 卡环的防锈止退螺母,使用该螺母可以防止螺母与螺 栓的锈蚀和松动,尤其适用于矿山、井下作业的机械 固定。

Description

本实用新型涉及一种防锈密封止退螺母,属于紧固或固定构件或机械零件用的器件。
目前所使用的螺母与螺栓在结合部位极易生锈,常常出现螺母与螺栓锈蚀在一起拆卸不下来的情况,只好将螺栓锯断,给工作人员的安装带来不便。专利号90223530.3,名称为″一种防锈密封螺母″的专利提供了一种装有防锈密封环的螺母,采用尼龙圆环镶在螺母凹槽内,即可密封防锈又可以起到紧固防震作用。但是仅靠尼龙内套的紧固摩擦还不能彻底解决螺母的松动问题。
本实用新型的目的是在防锈密封螺母的基础上通过嵌入刚性棘齿卡环的方法,使螺母具有止退功能。
本实用新型是在防锈密封螺母的端面设计一圆柱凸起,圆柱内有环形凹槽,凹槽内镶有尼龙圆环,在尼龙圆环与螺母的接触端面之间嵌有带棘齿的止退卡环。卡环可制成两个半圆环止退卡环的棘齿为2个或多个,止退卡环亦为两个半圆偏心环形钢片。
下面结合附图详细说明本实用新型的实施例:
图1为防锈密封止退螺母结构示意图。
图中,1.螺母圆柱凸起;
2.尼龙圆环;
3.螺母圆柱内侧环形凹槽;
4.止退卡环;
图2为棘齿止退卡环结构图。
图中5.止退棘齿。
图3为偏心圆止退卡环结构图。

Claims (3)

1、一种防锈密封止退螺母,在螺母的一个端面有圆柱凸起,圆柱内有环形凹槽,凹槽内镶有尼龙圆环,其特征在于在尼龙圆环与螺母接触的端面之间嵌有带棘齿的止退卡环。
2、根据权利要求1所述的防锈止退螺母,其特征在于止退卡环的棘齿为2个或多个。
3、根据权利要求1所述的防锈止退螺母,其特征在于止退卡环为两个半圆偏心环形钢片。
