Description

带有防插功能的插芯门锁
技术领域
本实用新型涉及锁具,具体涉及一种带有防插功能的插芯门锁。
背景技术
在已有的同类产品中,很多锁体设有的防插结构,但存在有结构比较复杂,体积偏大,性能不够稳定和生产成本高的缺陷。
发明内容
本实用新型的目的是为可服上述不足,提供一种结构简单防插效果好的插芯门锁。
本实用新型的目的是用下述的技术方案实现的,带有防插功能的插芯门锁,包括防插舌、斜舌、传动片、防插保险、锁壳、拨动杆、连动销、防插舌弹簧、防插保险扭簧和定位销,其特征在于:在锁壳内斜舌的一侧,设有呈枪状的防插保险,防插保险的柄部一端与定位销呈可摆动的状态连接,防插保险扭簧套在定位销上,一端与锁壳的侧壁相作用,另一端与防插舌保险的柄部相作用,防插舌的两端分别与锁壳和定位销呈直线滑动装配,在定位销的一端设有槽,槽内装置有弹簧,在槽体的前端的外侧加工有销孔,销孔内装配有连接销,防插舌与传动片用连接销呈活动连接。
所述的传动片是呈T形,内侧的端部与防插保险的杆部的外侧呈线性接触。
本实用新型的工作原理是:开门状态时,防插舌弹簧将斜舌顶出,且通过连动销使传动片摆动而拨动防插保险是其离开斜舌伸缩的轨迹线,达到斜舌可以自由伸缩防插保险。闭门状态时,门框将防插舌压入,且通过连接销使传动片拖离防插保险,则防插保险扭簧将防插保险拨动到斜舌伸缩的轨迹线,达到斜舌不可以伸缩;正常开启时由拨动杆拨动连动板,连接板拨动防插保险使其离开斜舌伸缩的轨迹线,达到斜舌可以收缩到锁体内。
本实用新型的优点是:结构简单,防插效果好。
