Abstract

一种双边柱栓内铣牙钥匙弧形叶片弹子锁装置，该装置包括锁头体3，外锁芯2，衬套8，内锁芯1，弧形叶片弹子4，叶片弹子弹簧5，边柱栓6，边柱栓弹簧7，内铣牙钥匙等，其特征是所述叶片弹子弹簧5是两侧有梳齿状悬臂的片状弹簧，内锁芯1径向有一组圆心角对顶的扇形弹簧槽9，弧形叶片弹子4内侧有与片状弹簧悬臂末端配合的卡口43，有与钥匙内铣牙配合的凸台41；该装置弹子密度高，装配方便，可有效防止塑料薄膜之类工具非正常开锁。

Description

双边柱栓内铣牙钥匙弧形叶片弹子锁
本发明涉及一种钥匙内铣牙、使用片状弹子弹簧的弧形叶片弹子锁装置。 
现有内压边柱栓式弧形叶片弹子锁，大多是螺旋弹簧、外铣牙钥匙，当柔而有弹性的薄膜之类塞入锁眼时会减弱螺旋弹簧的弹力，在叶片弹子回弹时，v形缺口碰到边柱栓就会搁止，易使v形缺口排成一列而非正常打开。为了克服上述问题，本发明的技术方案是：采用整体式片状弹子弹簧，采用内铣牙钥匙，使只有向外张力的薄膜无法非正常打开锁具。 
本发明所述的双边柱栓内铣牙钥匙弧形叶片弹子锁装置：包括锁头体，外圆有弧形叶片弹子沟槽的内锁芯，两侧有与边柱栓式锁键配合滑槽的圆筒形外锁芯和衬套，两个边柱栓及边柱栓弹簧，有弧形或v形缺口的弧形叶片弹子组，片状弹子弹簧，钥匙等。所述内锁芯径向有一组圆心角对顶的扇形弹簧槽；所述片状弹子弹簧左右两侧有梳齿状的悬臂，臂的间距、数量与叶片弹子组对应；所述弧形叶片弹子内侧有与片状弹簧悬臂末端配合的卡口，锁眼端有与钥匙内铣牙配合的凸台；所述钥匙有两列内铣牙。 
本发明所述的双边柱栓内铣牙钥匙弧形叶片弹子锁装置，弹子密度高，装配方便，可有效防止塑料薄膜之类工具非正常开锁。下面结合应用实施例及附图作进一步说明。 
附图1是本发明所述双边柱栓内铣牙钥匙弧形叶片弹子锁装置 闭合状态的结构示意图。 
左右梳齿状的片弹子弹簧5装于内锁芯1的径向对顶扇形弹簧槽9内，弹簧5两侧悬臂末端分别嵌入叶片弹子的卡口43之内；叶片弹子4有v形缺口42，有与钥匙内铣牙配合的凸台41；钥匙拔出时，叶片弹子4受弹簧5作用向上移动，边柱栓6脱出v形缺口42，外侧进入锁头体3的键槽内，外锁芯2不能转动，锁具闭合，如附图1所示。原配钥匙插进锁眼10时，在内铣牙作用下弹子4向下移动，所有v形缺口42排成一列，边柱栓6在弹簧7作用下进入v形缺口与外锁芯2表面齐平，内、外锁芯可同时转动，锁具开启。非原配钥匙插入锁眼，叶片弹子的v形缺口不能排成一列，边柱栓6不进入v形缺口，外锁芯2不转，内锁芯1空转，锁具不能开启。锁芯衬套8可防止内锁芯空转时边柱栓6滑入锁眼。即使有薄膜之类塞入锁眼，也只能将弹子向两侧挣开，不能使v形缺口排成一列而非正常开锁。
