Abstract

一种带锁键的螺桩,它的构成由螺桩和锁键两组件构成,所述螺桩一端为间隙螺纹端,另一端为过盈螺纹端,所述过盈螺纹端上开设有键槽,键槽槽深为1.15mm‑1.25mm。本实用新型易于加工,生产效率高、便于批量生产、安装方便;键槽槽深为1.15mm‑1.25mm防松效果更好,由于太浅过盈螺纹端达不到防松的效果,太深影响过盈螺纹端的强度。

Description

一种带锁键的螺桩
技术领域
本实用新型涉及紧固件领域,尤其涉及一种带锁键的螺桩。
背景技术
发动机机匣在与结构连接时,往往先用过盈螺纹螺桩的过盈端与机体底座连接,再在螺桩上装上机身及其他部件。螺桩在发动机运转过程中由于振动往往会发生松脱。
实用新型内容
本实用新型的目的是为了克服现有技术中的不足,从而提供一种根据防松需求,在螺桩过盈端增加锁键装置,可预防螺桩松脱的带锁键螺桩。
一种带锁键的螺桩,它的构成由螺桩和锁键两组件构成,所述螺桩一端为间隙螺纹端,另一端为过盈螺纹端,所述过盈螺纹端上开设有键槽,键槽槽深为1.15mm-1.25mm。
采用上述技术方案的有益效果是:
本实用新型易于加工,生产效率高、便于批量生产、安装方便;键槽槽深为1.15mm-1.25mm防松效果更好,由于太浅过盈螺纹端达不到防松的效果,太深影响过盈螺纹端的强度。
附图说明
图1为本实用新型带锁键的螺桩结构示意图。
图2为图1中螺桩结构示意图。
图3为图2的右视图。
图4为图1中锁键结构示意图。
图5为图4的俯视图。
图6为图4的左视图。
图中:1-螺桩、2-锁键、3-间隙螺纹端、4-过盈螺纹端、5-键槽。
具体实施方式
下面结合附图对本实用新型作进一步详细说明:
一种带锁键的螺桩,如图1所示,它的构成由螺桩1和锁键2两组件构成,如图2、3所示,所述螺桩1一端为间隙螺纹端3,另一端为过盈螺纹端4,所述过盈螺纹端4上开设有键槽5,锁键2的压扁端镶嵌到螺桩2的键槽5里采用过盈配合。安装时将锁键2翻铆镶嵌到基体中,防止螺桩1自动松脱;键槽5槽深为1.15mm-1.25mm。
本实用新型通过在螺桩的过盈端开键槽,在键槽上装入锁键,过盈端拧入基体后,再将锁键翻铆嵌入机体中,防止螺桩在振动过程中松脱。
