Abstract

一种防前翻的锁,其特点是在底座与安装面之间有弹力装置,该弹力装置的弹力是推动锁体向外转动,开锁后,锁体在弹力作用下向外转动,锁体受弹簧弹力只往背离罩盖的方向翻转,让出罩盖下落的空间,避免打对锁。其优点是锁具开锁后向外翻转,不被罩盖砸到,简单实用。

Description

防前翻的锁
技术领域
本实用新型的涉及一种使用在工程车辆上,特别适用于挖掘机发动机罩防前翻的锁。 
背景技术
目前国内生产和使用的工程机械上使用的锁特别是挖掘机发动机罩锁具无此防前翻的功能,在打开发动机罩锁具时,锁具可前后翻转,若向前翻,会被盖下来的发动机罩砸到,导致损伤。 
实用新型内容
本实用新型的目的就是提供一种使锁具不被罩盖砸到导致损坏的防前翻的锁。 
本实用新型的解决方案是这样的:其锁体的底座与支撑面用销轴铰接,在底座与安装面之间有弹力装置,该弹力装置的弹力是推动锁体向外转动,开锁后,锁体在弹力作用下向外转动,锁体受弹簧弹力只往背离发动机罩的方向翻转,让出发动机罩下落的空间,避免打对锁。 
本实用新型的优点是锁具开锁后向外翻转,不被罩盖砸到,简单实用。 
附图说明
附图1是本实用新型的结构示意图。 
附图2是本实用新型在锁紧状态时的结构示意图。 
附图3是本实用新型在锁打开状态时的运动示意图。 
附图4是本实用新型所用的弹簧4示意图。 
具体实施方式
本实施例是应用于挖掘机发动机罩,包括有锁体1、底座2、销轴3、弹簧4。 
其锁体1的底座2与支撑面用销轴3铰接,在底座2与安装面之间有弹力装置,该弹力装置的弹力是推动锁体1向外转动。 
本实施例中,所述的弹力装置是在销轴3上套接有如附图4所示的弹簧4,弹簧4的一端与支撑面连接,另一端与底座2连接。 
开锁时,如附图3所示方向拉动开锁后,弹簧4将锁体弹离只往背离发动机罩的方向翻转,让出发动机罩下落的空间,避免打对锁。 

Claims (2)
