Abstract

本实用新型一种2个拨头的B级锁芯,2个锁心分别从两端装入锁心壳的孔中,锁心上有挡圈槽,分别将2个轴向挡圈卡入锁心上的挡圈槽内,锁心可以在锁心壳内旋转而不能轴向移动,拨块支承在2个锁心端部外圆上,拨块中间有槽,用钥匙伸入钥匙孔至附图6的槽中,钥匙转动,带动锁心在锁心壳内旋转并带动拨块同时旋转,带动相关机构动作,实现开锁动能。

Description

一种2个拨头的B级锁芯
技术领域
本实用新型专利涉及监狱安防领域,尤其涉及到监狱中监室安防门用锁。
背景技术
监狱安防门原来一般采用的B级锁芯只有一个拨头,限制了B级锁芯用途的拓展。
发明内容
本发明的目的是提供一种新的锁芯,这种新的锁芯具有2个拨头,使锁的用途更广泛。
本实用新型一种2个拨头的B级锁芯由钥匙、锁心壳、锁心、2个挡圈和拨块所组成,其特征在于,2个锁心装在锁心壳内,用轴用挡圈限制锁心轴向移动,拨头有2个拨块,支承在锁心的外圆上,钥匙插入钥匙孔带动锁心旋转时,拨头同时旋转,拨头上的2个拨块同时绕锁心旋转,带动相关机构动作,实现锁舌开启或关闭。
附图说明
图1是原锁芯的主视图
图2是原锁芯的侧视图
图3是原锁芯的A-A剖视图
图1和图2中,1-1是锁心壳,1-2是锁心,锁心上有挡圈槽,锁心可以在锁心壳内旋转,1-3是钥匙孔,1-4是拨头,1-5是轴向挡圈,2个锁心分别从两端塞入锁心壳孔中后,将轴向挡圈卡入锁心上的挡圈槽内,锁心在锁心壳内只能转动不能轴向移动;拨头支承在锁心端部的外圆上,用钥匙伸入钥匙孔至附图3的槽中,钥匙转动,带动锁心在锁心壳内旋转并带动拨块同时旋转,带动相关机构动作,实现开锁动能。
图4是本实用新型的主视图
图5是本实用新型的侧视图
图6是本实用新型的A-A剖视图
本实用新型的基本结构与原结构基本相同,仅将原来拨块上的1个拨头改为2个拨头。图4和图5中,1-1是锁心壳,1-2是锁心,锁心上有挡圈槽,1-3是钥匙孔,2-4是拨头,拨头中间有槽,1-5是轴向挡圈。
具体实施方式
2个锁心分别从两端装入锁心壳的孔中,锁心上有挡圈槽,分别将2个轴向挡圈卡入锁心上的挡圈槽内,锁心可以在锁心壳内旋转而不能轴向移动,拨块支承在2个锁心端部外圆上,拨块中间有槽,用钥匙伸入钥匙孔至附图6的槽中,钥匙转动,带动锁心在锁心壳内旋转并带动拨块同时旋转,带动相关机构动作,实现开锁动能。
本实用新型一种2个拨头的B级锁芯由钥匙、锁心壳、锁心、2个挡圈和拨块所组成,其特征在于,2个锁心装在锁心壳内,用轴用挡圈限制锁心轴向移动,拨头有2个拨块,支承在锁心的外圆上,钥匙插入钥匙孔带动锁心旋转时,拨头同时旋转,拨头上的2个拨块同时绕锁心旋转,带动相关机构动作,实现锁舌开启或关闭。
