Abstract

一种密封螺母，包括螺母本体，在螺母本体内壁中间沿着螺纹轨迹设有至少一圈螺旋状的凹槽，凹槽内粘有橡胶条。采用本实用新型密封螺母，密封效果好，从而减少锈蚀，减轻检修工作量，有效保护螺母和螺杆的工作寿命。

Description

密封螺母
技术领域
本实用新型属于机械领域，尤其涉及一种电力系统用密封螺母。
背景技术
目前的螺母不具有密封的功能，只起到固定作用，经过长时间风吹日晒，进水螺母和螺杆之间会生锈，在检修过程中不易松动，增加工作量，甚至会破坏螺母或者螺杆，造成不必要的损失。
实用新型内容
本实用新型所要解决的技术问题是提供一种防止锈蚀和密封良好的螺母。
为了解决上述技术问题采用以下技术方案：一种密封螺母，包括螺母本体，在螺母本体内壁中间沿着螺纹轨迹设有至少一圈螺旋状的凹槽，凹槽内粘有橡胶条。
所述的凹槽为螺旋状的两圈。
橡胶条的厚度不超过凹槽的深度。
采用本实用新型密封螺母，密封效果好，从而减少锈蚀，减轻检修工作量，有效保护螺母和螺杆的工作寿命。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
如图1所示，一种密封螺母，包括螺母本体1，在螺母本体1内壁中间沿着螺纹轨迹设有两圈螺旋状的凹槽2，凹槽2内粘有橡胶条3。橡胶条3的厚度和凹槽2的深度相配合。

Claims (3)

1.一种密封螺母，包括螺母本体，其特征是：在螺母本体内壁中间沿着螺纹轨迹设有至少一圈螺旋状的凹槽，凹槽内粘有橡胶条。
2.根据权利要求1所述的密封螺母，其特征是：所述的凹槽为螺旋状的两圈。
3.根据权利要求1所述的密封螺母，其特征是：橡胶条的厚度不超过凹槽的深度。
