Abstract

本发明是让弹子独立的磁性空转锁头，壳体内有前锁芯和后锁芯，前锁芯上有边柱，边柱上有磁铁，前锁芯上有弹子，弹子上有磁体，边柱上的磁铁与弹子上的磁铁相互排斥，边柱上有另一个磁铁，钥匙上有磁性金属，边柱上的磁体与钥匙上的磁性金属相互吸引，边柱上有弹簧，弹簧使边柱轴向后移动，使弹子不会和边柱接触，弹子的一端有弹簧，弹子上的弹簧使弹子可以伸缩，前锁芯的侧面有凹槽，卡片由壳体伸入凹槽内，轴向固定前锁芯，前锁芯可自由旋转，后锁芯的一端有与边柱配合的凹槽。

Description

让弹子独立的磁性空转锁头
技术领域
本发明属于机械锁具，提供让弹子独立的磁性空转锁头。
背景技术
现有机械锁头中的弹子与对应机构在外力的作用下或者始终有持续的接触，因此可以直接试探弹子的正确对应位或者间接得到对应机构的自动响应，所以大部分不能防止试探拨动弹子找到对应位，及基本上不能防止快速拨动弹子，概率性使弹子对位等技术开启。
发明内容
本发明利用磁性原理使对应机构与弹子在外力的作用下没有直接的接触，不能直接试探弹子的正确对应位或者间接得到对应机构的自动响应，从而有效防止以上技术开启，并在无匙开启时空转。
本发明技术方案：壳体内有前锁芯和后锁芯，前锁芯上有边柱，边柱上有第一磁铁，前锁芯上有弹子，弹子上有磁体，边柱上的第一磁铁与弹子上的磁体相互排斥，边柱上还有第二磁铁，钥匙上有磁性金属，边柱上的第二磁铁与钥匙上的磁性金属相互吸引，边柱上有弹簧，弹簧使边柱轴向后移动，使弹子不会和边柱接触，弹子的一端有弹簧，弹子上的弹簧使弹子可以伸缩，前锁芯的侧面有凹槽，卡片由壳体伸入凹槽内，轴向固定前锁芯，前锁芯可自由旋转，后锁芯的一端有与边柱配合的凹槽。
在没有插入正确的钥匙时，边柱上的第二磁铁与钥匙上的磁性金属相互吸引，边柱轴向前移动，边柱上的第一磁铁与弹子上的磁体相互排斥，边柱上的弹簧因此压缩，使得边柱不会和弹子相接触，前锁芯空转。插入正确钥匙时，弹子上的缺口与边柱上的第一磁铁对齐，钥匙上的磁性金属与边柱上的磁铁相互吸引，边柱轴向前移动，边柱上的第一磁铁不会被弹子上的磁体所排斥，边柱的一端进入后锁芯凹糟内，顺时针方向和逆时针方向扭动前锁芯，边柱带动后锁芯一起转动进而开锁。拨出钥匙后，钥匙上的磁性金属和边柱上的第二磁铁相互吸引，边柱复位，弹子被弹簧推动复位，后锁芯被后背锁弹簧推动复位。
附图说明
下面结合附图和实施例进一步说明本发明技术方案：
图1是前锁芯主视局部剖视图；
图2是后锁芯主视图；
图3是闭锁时的全锁俯视内部结构图；
图4是开锁时的全锁俯视内部结构图；
图5是边柱图；
图6是弹子图；
图7是钥匙图；
图8是边柱立体图；
图9是弹子立体图。
具体实施方式
图1至9所示的实施例中，壳体1内有前锁芯2和后锁芯3，前锁芯2上有边柱5，边柱5上有第一磁铁7，前锁芯2上有弹子4，弹子4上有磁体8，边柱5上的第一磁铁7与弹子4上的磁体8相互排斥，边柱5上还有第二磁铁9，钥匙0上有磁性金属10，边柱5上的第二磁铁9与钥匙0上的磁性金属10相互吸引，边柱5上有弹簧6，弹簧6使边柱5轴向后移动，使弹子4不会和边柱5接触，弹子4的一端有弹簧11，弹子4上的弹簧11使弹子4可以伸缩，前锁芯2的侧面有凹槽，卡片12由壳体伸入凹槽内，轴向固定前锁芯2，前锁芯2可自由旋转，后锁芯3的一端有与边柱5配合的凹槽。
离合原理：在没有插入正确的钥匙时，边柱5上的第二磁铁9与钥匙0上的磁性金属10相互吸引，边柱5轴向前移动，边柱5上的第一磁铁7与弹子4上的磁体8相互排斥，边柱5上的弹簧6因此压缩，使得边柱5不会和弹子4相接触，前锁芯2空转。插入正确钥匙时，弹子4上的缺口与边柱5上的第一磁铁7对齐，钥匙0上的磁性金属10与边柱5上的磁铁9相互吸引，边柱5轴向前移动，边柱5上的第一磁铁7不会被弹子4上的磁体8所排斥，边柱5的一端进入后锁芯3凹糟内，顺时针方向和逆时针方向扭动前锁芯2，边柱5带动后锁芯3一起转动进而开锁。拨出钥匙后，钥匙0上的磁性金属10和边柱5上的第二磁铁9相互吸引，边柱5复位，弹子4被弹簧11推动复位，后锁芯3被后背锁弹簧推动复位。
附言：在开锁完毕拔出钥匙时，钥匙的每一个齿面都较长，在弹子卡死时，钥匙可以轴向稍许移动，否则不能拔出钥匙。钥匙缺口附近没有磁性，磁铁离钥匙缺口有一定距离。以门锁为例，门外插入钥匙的即为锁头，门内可以直接扭动的即是说明书中所指的后背锁。
