Description

防盗双锁胆锁芯
技术领域
本发明涉及锁芯新品种。
背景技术
众所周知，已有锁具开启机构-锁芯，包括锁胆、锁胆座、弹珠和弹珠弹簧；它为单锁胆锁芯，在锁紧状态时，锁胆是不能转动的，故它存在防盗性差的弊端：一是用非原配钥匙和工具插进锁胆钥匙孔偷开锁，弹珠容易被拨弄到开启状态而把锁开启；二是用电钻钻锁胆，破坏弹珠，也可把锁开启。
发明内容
本发明的目的在于提供一种能克服上述弊端的防盗双锁胆锁芯。
本锁芯包括锁胆座、外锁胆、内锁胆、弹珠弹簧、平珠、上弹珠、下弹珠、复位弹簧和拨轮；外锁胆为套管形，它装在锁胆座和内锁胆之间，平珠为扁圆形体，上、下面为球面，平珠安装在上弹珠与弹珠弹簧之间，内锁胆尾部略小，外套装有复位弹簧，复位弹簧外端压在外锁胆内凸缘上，锁芯在锁紧状态时，拨轮拨板处在锁舌拨板槽之外。
工作原理：本锁芯在锁紧状态时，内胆尾部拨轮拨板在锁舌拨板槽之外，而外锁胆和锁胆座接触面放的是平珠，故外锁胆可转动；
当用非原配钥匙和工具插进内锁胆钥匙孔偷开锁时，转动内锁胆却带动外锁胆一起转动，无法拨弄所有弹珠到开启状态，锁无法开启；
当用电钻钻内锁胆，企图破坏弹珠时，内锁胆与外锁胆与钻头一起转动，无法钻进去；
当用原配钥匙插进内锁胆钥匙孔时，弹珠处于开启状态，再把钥匙与内锁胆一起往里推进，压缩复位弹簧，转轮拨板便插进锁舌拨板槽里，转动钥匙，锁舌退出锁孔，锁便开启。
本发明特点是：本锁芯在锁紧状态下，内锁胆与外锁胆可一起转动，窃贼用非原配钥匙或工具无法开启，用电钻无法破坏，防盗性能好。
附图说明
附图为本锁芯纵剖示意图。
具体实施方式
参照附图，本锁芯包括锁胆座1、外锁胆2、内锁胆3、弹珠弹簧4、平珠5、上弹珠6、下弹珠7、复位弹簧8和拨轮9；外锁胆2为套管形，它装在锁胆座1和内锁胆3之间，平珠5为扁圆形体，上、下面为球面，平珠5安装在上弹珠6与弹珠弹簧4之间，内锁胆3尾部略小，外套装有复位弹簧8，复位弹簧8外端压在外锁胆2内凸缘21上，锁芯在锁紧状态时，拨轮9拨板91处在锁舌拨板槽之外。
