Abstract

本发明采用控制弹子作同向直线(离心/向心)运动的结构方式，锁体.锁芯上加工有径向相对应不同孔径(大小)的两排弹子孔，其轴向位置相等，钻孔深度贯穿锁芯匙槽。锁头中装配不同尺寸的两排弹子，大直径弹子控制原理同传统锁头；向心(由锁体进入锁芯)运动控制锁芯，离心(退出锁芯)运动解锁。小直径弹子相反；离心(由锁芯进入锁体)运动控制锁芯，向心(退出锁体)运动解锁。

Description

一种防技开的弹子锁头
技术领域
本发明属于机械式锁具，涉及一种控制弹子作同向直线(离心/向心)运动的防盗锁头。所属领域为安全防范领域。
背景技术
现流行各种技术开启锁具的手段，如：单钩、撞击、电动冲击等，其无一例外有一个共同点，须先扣紧锁芯产生预开压力，然后实施对弹子位置强制移动达到开锁目的。通过分析单钩技开过程：这一过程将锁芯弹子孔相对锁壳弹子孔产生一定偏差，形成肩台，逐个移动各控制弹子退出锁芯弹子孔，在弹簧压力下，弹子落位在锁芯外元上(肩台)进而旋转打开锁具。
传统弹子锁头控制弹子相对锁芯均作退出(离心)运动完成解锁。
技开锁头中预先扣紧是开锁中的核心动作，有了这一动作，才有了锁具被打开的结果，反之，则无技开的可能。
发明内容
为了达到在技术层面排斥预先扣紧动作，本发明采用控制弹子作同向直线(离心/向心)运动的结构方式，具体技术方案是：锁体.锁芯上加工有径向相对应不同孔径(大小)的两排弹子孔，其轴向位置相等，钻孔深度贯穿锁芯匙槽。锁头中装配不同尺寸的两排弹子，大直径弹子在弹簧作用(张力)下穿过匙槽，落位于匙槽边(小弹子孔边，形成稳定的基准。)顶住小直径弹子，小直径弹子的弹簧在大直径弹子的压力下保有一定的弹力(张力)。大直径弹子控制原理同传统锁头；向心(由锁体进入锁芯)运动控制锁芯，离心(退出锁芯)运动解锁。小直径弹子相反；离心(由锁芯进入锁体)运动控制锁芯，向心(退出锁体)运动解锁。
本发明采用上述锁定结构方式中的弹子(向心)运动解锁条件，可有效制约非配套钥匙开锁的各种方式，提高锁具防开防盗性能。
附图说明
图1是本发明的主视图；
图2是图1的截面剖视图；
图3是图1的AA剖视图；
图4是图3插入钥匙解锁示意图。
具体实施方式：
锁头由锁体1锁芯2组成，锁芯上加工有匙槽9，锁头内装有大直径弹子3和4，小直径弹子5和6，在弹簧7的作用下，弹子4顶住弹子5，弹簧8保有一定张力。弹子3和5是控制锁芯弹子，在钥匙10插入匙槽9开锁状态下，钥匙10挤压弹子4压迫弹子3退出锁芯，弹簧8通过弹子6将弹子5顶退出锁体。
