Description

磁码防盗弹子锁
本实用新型涉及一种锁具,特别是一种磁码防盗弹子锁。
目前的锁具,特别是门锁,一般都采用弹子锁,结构简单、可靠性安全性较差,无防盗功能。而现行的防盗锁有四角弹子锁,仅管四角装有弹子,但容易错位,同时也不能防开,同样防盗功能不强。
本实用新型的目的在于设计一种不易错位,防开,且具有较强防盗作用的磁码防盗弹子锁。
本实用新型的目的是这样实现的,一种磁码防盗弹子锁,包括有外壳、锁芯、弹子、弹簧、固定卡及拨动锁舌的连接杆,其特点是在不同一横截面上锁芯与外壳上设有四组磁芯,每组磁芯的相同磁极一一相对组合。
由于每组磁芯同极相对设置,利用同极相斥的磁性原理,使磁芯与锁壳牢牢卡死,锁芯不会轻易转动,只有当该锁钥匙插入,因在钥匙的相应位置同样设有与锁芯相应位置的磁芯磁极相对的磁芯,利用它们的同极相斥原理,将锁芯上的磁芯沿外壳的同轴孔推移,从而使锁芯可沿外壳内孔转动,配合弹子的移动,通过连接杆带动锁舌,从而打开该锁,只要不是使用该锁钥匙,无论任何工具都无法开启该锁,从而达到防盗目的。
按本实用新型提供的磁码防盗弹子锁,结构简单、不易错位、防开、具有极强的防盗作用。
本实用新型的附图为磁码防盗弹子锁的结构示意图。

下面参照附图说明本实用新型的实施方案,磁码防盗弹子锁如附图所示,包括有外壳1、锁芯2、弹子3、弹簧4、固定卡6及拨动锁舌的连接杆7,其特点是在不同一横截面上锁芯2与外壳1上设有四组磁芯5,每组磁芯的相同磁极一一相对组合。本例中每对磁芯为N-N极相对组合。
