Description

安全锁芯
本实用新型涉及一种锁具中用的锁芯。
一般的锁芯采用铜合金制造,直接置于锁具中。因此,一般的锁芯防撬、防敲打的性能较差,容易被破坏。而且锁芯的钥匙孔必须露出,没有防护,很容易被冲击钻等工具破坏而不能使用,安全性能不够理想。
本实用新型目的是针对现有技术的不足,设计一种防撬、防敲打性能较好,安全性较高的锁芯。
本实用新型的锁芯本体外罩有防护罩,防护罩的里端开口,外端面设有通孔,安全片置于锁芯本体的外端面和防护罩的外端内壁之间滑动配合,在安全片上设有和锁芯本体上的钥匙孔相应的通槽。
本实用新型采用了防护罩及安全片,防敲打、防冲击能力明显提高,安全片置于防护罩内滑动配合,丝毫不影响钥匙开锁。并且本实用新型结构简单,制造容易。
下面结合附图和实施例进一步阐明本实用新型。
图1是实施例的主视图;
图2是图1的俯视图。
如图示,锁芯本体1外罩有防护罩2,防护罩2的里端开口,外端面设有通孔4。安全片3置于锁芯本体1外端面和防护罩2的外端内壁之间滑动配合,在安全片3上设有通槽5和锁芯本体1上的钥匙孔对应。本实施例防护罩2及安全片3采用表面渗碳的白钢,硬度很高,防撬、防敲击的性能非常好,可以提高整个锁具的安全性。安全片3可以滑动,这样用钥匙开锁时不会受到影响,而且不使用时将安全片3转过一定角度,还可以遮挡钥匙孔防尘。
