Description

密码防盗门锁
目前使用的门锁,都是锁门后拔出钥匙的传统方法,钥匙孔暴露在外面,容易被窃贼用万能钥匙开锁入门盗窃。先进的电子数码锁需用电源且售价昂贵,难以普及使用。
本实用新型的目的是设计一种能防止用万能钥匙开锁的安全门锁。
本实用新型的目的是这样实现的:门框上安装密码锁头,锁头前后两面都有几个相同的小窗口,露出部分带数字的密码圆轮,圆轮与锁心开启机构相连,锁头一个侧面有与钥匙形状相应的钥匙孔。在门板上安装钥匙盒,盒前后两面各有一个锁把,锁把控制侧面的钥匙的出入。圆轮上的数字可组成几百万个密码,不知道密码欲开锁的机率是几百万分之一,保密性强。锁门时转动锁把,将钥匙插入钥匙孔里,再拨乱密码圆轮,门就锁上了,因钥匙是藏在钥匙孔里就杜绝了用万能钥匙开锁的可能性。当拨动密码圆轮与原予设的密码相同时,钥匙既可拔出,门就打开了。
由于采用上述方案,革新了传统锁的结构和开启方式,提高了锁的保密性和安全性。制造工艺简单易行。
下面结合附图和实施例对本实用新型进一步说明:
如图是密码防盗门锁实施例结构示意图:1、门框  2、密码  3、密码圆轮  4、钥匙孔  5、钥匙  6、门把  7、门钥匙盒
