Abstract

本发明涉及一种锁具锁头的启闭装置,其锁头体内控制锁具启闭的装置,将边柱栓式结构与传统的弹子式结构有机结合,所用钥匙为三向三列、非对称设计;与现有的单一结构锁头启闭装置相比,更难被技术性开锁,可用于安全性要求较高的各类锁具。

Description

一种锁头启闭装置
本发明涉及一种锁具锁头的启闭装置。
现有的机械式锁头启闭装置有弹子式结构、叶片式结构或者边柱栓式结构等,但是同一锁头大都只采用一种结构形式,容易被某种手段技术性开锁。
本发明的目的在于提供一种能进一步提高锁具防技术性开锁性能的锁头启闭装置。
本发明所述的锁具锁头启闭装置包括:钥匙、外表面有弧形沟槽的圆柱形内锁芯,两侧有锁键滑槽的圆筒形外锁芯,两个柱栓式锁键及锁键弹簧,两组对称布置于内锁芯弧形沟槽内的弧形滑片及滑片弹簧,内侧有两道轴向键槽的锁头体等,其特征是:所述钥匙有三向三列齿爪、横断面呈ω形;所述内锁芯、外锁芯中有一列与钥匙插槽相通的径向弹子孔,孔内装有锁芯弹子;所述锁头体与锁芯弹子孔对应位置也有一列径向弹子孔,孔内装有锁头弹子及弹子弹簧;所述内锁芯与外锁芯结合面处的钥匙插槽横断面呈ω形;所述锁键弹簧为弓形片状弹簧,并装于锁头体的轴向键槽之内;所述外锁芯与内锁芯以销钉连接、联动,其后端延伸至本启闭装置外部,以带动锁具系统动作。
本发明提供的锁具锁头的启闭装置,将边柱栓式结构与传统的弹子式结构有机结合,所用钥匙为三向三列、非对称设计,与现有的单一结构锁头启闭装置相比,更难被技术性开锁,可用于安全性要求较高的各类锁具。
附图说明:
附图1是本发明锁头启闭装置实施例的闭合状态结构示意图;
附图2是本发明锁头启闭装置实施例的开启状态结构示意图;
下面结合附图1、附图2对实施例作进一步说明:实施例中,所述的锁头启闭装置包括:钥匙20,圆柱形内锁芯3、圆筒形外锁芯2、柱栓式锁键4、片状锁键弹簧5、弧形滑片6、滑片弹簧7,锁头体1、锁芯弹子8、锁头弹子9等。所述钥匙20横断面呈w形,三个方向各有一列齿爪;所述圆柱形内锁芯3外表面的弧形沟槽15内有弧形滑片6及滑片弹簧7,所述内锁芯3和外锁芯2内有一列与钥匙插槽11相通的径向弹子孔,孔内有锁芯弹子8;所述锁头体1的两道轴向键槽12中间有一列装有锁头弹子9和弹子弹簧10的径向弹子孔。当钥匙拔出后,滑片6在弹簧7作用下向下移动,锁键4外侧一部分被滑片6外缘顶入锁头体1的键槽12内,同时弹子9的一部分也被弹子弹簧10向下顶入锁芯上的弹子孔内,致使内、外锁芯不能转动,锁具处于闭合状态,如图1所示。当原配钥匙20插入ω形钥匙插槽11时,弧形滑片6向上移动,当左右两侧两组滑片6外缘上的弧形缺口14都分别对齐成一直线时,两锁键4在锁键弹簧5的作用下,其弧形内侧面进入滑片弧形缺口14,使锁键4的外侧面与外锁芯2的外圆柱面齐平,锁芯可转动,锁具处于开启状态,如图2所示。

Claims (4)

1.一种锁头启闭装置,该装置包括:钥匙20、外表面有与轴线垂直的弧形沟槽15的圆柱形内锁芯3、两侧有锁键滑槽的圆筒形外锁芯2、两个柱栓式锁键4、锁键弹簧5、两组对称布置于内锁芯弧形沟槽15内的弧形滑片6和滑片弹簧7、内侧有两道轴向键槽12的锁头体1等,其特征是:所述钥匙20有三向三列齿爪、横断面呈ω形;所述内锁芯3与外锁芯2中有一列与钥匙插槽11相通的径向弹子孔,孔内装有锁芯弹子8;所述锁头体1与锁芯弹子孔对应位置也有一列径向弹子孔,孔内装有锁头弹子9及弹子弹簧10。
2.根据权利要求1所述的锁头启闭装置,其特征是所述锁键弹簧5为弓形片状弹簧,且装于锁头体1的轴向键槽12之内。
