Abstract

本实用新型是一种磁力防盗锁,主要特点是在至 少一条弹子滑道内取消弹性弹子设置磁性弹子,并在 钥匙牙齿的相应位置设置磁块牙齿,磁性弹子的数 量、位置、磁性强弱及滑动方向多变,与现有的弹子锁 相比,钥匙难以仿配,即使用齿形完全相符的钥匙也 难以盗开,具有防盗开性能显著提高,使用方便等优 点。

Description

本实用新型属于建筑技术领域,是一种磁力防盗锁。
现有的弹子锁,其锁芯中弹子为普通金属材料制成,钥匙开启锁芯全靠钥匙牙齿直接推动弹子及弹簧实现,在长期的使用中,容易发生仿配齿形相符的钥匙盗开弹子锁的弊端。
本实用新型的目的是设计一种使用齿形相符的钥匙也难于盗开的防盗锁。
本实用新型所采取的技术方案是对现有弹子锁的弹子和钥匙加以改进,即将至少一副弹性弹子改为磁性弹子,并将钥匙牙齿的相应位置设镶磁块牙齿,磁极相反。
本实用新型的这种磁力防盗锁具有防盗开性能提高的优点,即使用齿形完全相同的钥匙也难以盗开,钥匙难以仿配。
结合附图及实例进一步说明本实用新型的具体结构特征。
图1表示磁力防盗锁的锁芯及钥匙的一种实施例结构示意图;
图2表示磁力防盗锁锁芯及钥匙的又一种实施例结构示意图。
参见附图1,2,本实用新型磁力防盗锁包括锁体4、锁芯5、弹性弹子1、磁性弹子2、钥匙6、磁块牙齿7。在任意一条以上的弹子滑道内,设置永磁性弹子2,取消弹性弹子并在锁体4的滑道内设置铆钉3,铆钉3可为软磁铆钉(未充磁如图1),也可为铜铝等不能磁化材料的铆钉(如图2),在相应于磁性弹子2的钥匙6上的牙齿设置为磁块牙齿7,磁块牙齿7的磁极与磁性弹子2的磁极相反。磁性弹子的数量、位置及磁性强弱运动方向可多变。
钥匙6插入锁芯5中后,图1所示的磁性弹子2被磁块牙齿7的N极吸引作用,从与锁体4内的软磁铆钉3相吸状态(锁闭状态)落入锁芯5的通道内,图2所示的磁性弹子2从锁芯5的通道内(锁闭状态)被磁块牙齿7的S极排斥作用,升入锁体4的通道内,其它弹子被钥匙牙齿排入锁体4的通道内,此时,锁芯5和锁体4分开,转动钥匙锁芯,实现开启。
