Description

开口式自锁螺母
技术领域
本实用新型涉及一种开口式自锁螺母。
背景技术
    螺母用于装备连接,在复杂的工作环境中,六角开口式自锁螺母仍可能由于锁紧力矩消失,失去锁紧作用,使连接的装备从机体上脱落,从而造成装备的功能丧失,产生安全事故。 因此提高开口式自锁螺母的锁紧力和可靠性成为急需解决的问题。
实用新型内容
本实用新型目的是提供了一种锁紧限位效果好,外形美观、加工使用方便的开口式自锁螺母。
本实用新型解决技术问题提供如下方案:
一种开口式自锁螺母,包括螺母本体,其特征在于:所述螺母本体的内壁上设有螺纹,所述螺母的上端口部设有锥形端,所述锥形端的一端口部设有多道开口,所述相邻开口之间设有挡片,所述挡片具有弹性。
所述螺母的外壁为圆弧形。
本实用新型在螺母本体的内壁上设有螺纹,且在螺母的上端面设有锥形端,且在锥形端的端口部设有多道开口,且相邻开口之间设有弹性挡片,实现收缩紧固作用,使得螺母的锁紧效果更好。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
参见附图,一种开口式自锁螺母,包括螺母本体1,所述螺母本体1的内壁上设有螺纹2,所述螺母1的上端口部设有锥形端3,所述锥形端3的一端口部设有多道开口4,所述相邻开口4之间设有挡片5,所述挡片5具有弹性。
所述螺母1的外壁为圆弧形6。
