Abstract

本实用新型涉及一种紧固螺栓,特别是一种单旋向螺栓,主要解决了现有技术使用的螺栓无法在紧固后防止螺母反转,达到防松或人为拆卸破坏。主要技术特征是在螺杆沿轴线方向,设有深度不同的长槽,在长槽内设有防螺母反转的圆柱体,本实用新型具有结构简单、性能可靠等优点,可广泛用于一次性紧固联接使用,也可省去圆柱体后按一般螺栓使用。

Description

一种单旋向螺栓
本实用新型涉及一种紧固螺栓,特别是一种单旋向螺栓。
现有技术使用的螺栓,特别是在有防止螺母反转要求的螺栓,都是在螺母上增加机构,如防松垫片或是在螺母内螺纹与螺母体之间,增加防反转装置,现有技术普遍存有许多技术上的缺点,如结构复杂、成本高,或者是防反转效果差。
本实用新型的目的是设计一种结构简单、性能可靠,在不改变螺栓其它结构的同时,达到防螺母反转目的的新型螺栓。
本实用新型的目的是这样实现的,在螺杆沿轴线方向,设有深度不同的长槽,长槽沿螺纹锁紧方向变深,在长槽内,设有可在长槽内滚动以防螺母反转的园柱体。
以下结合附图对本实用新型进行描述。
附图1为本实用新型结构示意图。
附图2为附图1的剖示图。
参看附图,在螺杆1上沿轴线方向开有相对螺杆1外径深度不同的长槽2,长槽2沿螺纹锁紧方向变深,在长槽2内,设有防螺母4反转的园柱体3,园柱体3可在长槽2内滚动。本实用新型在使用时,螺母4在螺杆1上锁紧时,园柱体3在螺母4的作用下,滚动到长槽2的底部,不影响螺纹使用,当螺母4反转时,园柱体3在长槽2底部,向上滚动,卡住螺母4的内螺纹,使螺母不能反向转动,达到防反转的目的,长槽2在螺杆1的位置,可根据螺栓的使用长度确定。
本实用新型具有结构简单、性能可靠、成本低等特点,可广泛用于一次性紧固联接使用,能有效防止螺栓自然松动和防止人为拆卸破坏等。
