Description

一种密码锁的密码找回装置 技术领域
本实用新型涉及密码锁技术领域,特别涉及密码锁的密码找回装置。
背景技术
现有的密码锁，有时候密码会忘记,试错找密码操作复杂、锁一时无法打开,只能找专业开锁来解决,不仅耽误时间,还要付出费用,还不安全,如何能够不借助专业开锁人员能实现密码找回,这是我们当前急需解决的技术问题。
实用新型内容
本实用新型的目的是：提供一种密码锁的密码找回装置，以解决现有技术中存在的上述技术问题。
根据上述目的，本实用新型的基本技术方案为：一种密码锁的密码找回装置，包括锁体，所述的锁体外面设有弹性轮和内轮组合体，并通过大弹簧安装在锁壳和锁盖之间，所述的锁体上连接有锁把，所述的锁把内设有锁芯，其特征在于：所述的锁体内设有活动的调节杆，所述的调节杆与锁盖之间设有小弹簧，所述的调节杆上设有凸点，所述的内轮上设有让位卡槽和限位，在备用钥匙的转动下带动锁芯转动，锁芯与带动内轮转动的拨动盘上的凸块错位啮合，锁体在大弹簧的作用下相对移动，所述的调节杆在小弹簧的作用下向内移动，转动拨动盘带动内轮旋转，此时套在内轮外面的弹性轮不转动，所述的调节杆上的凸点与内轮内的限位卡住，所述的内轮外面密码轮上显示的密码就是找回的密码。
进一步的，所述的弹性轮内设有让位卡槽，所述的锁体上通过凸块与弹性轮和内轮组合体的让位卡槽相滑动啮合。
进一步的，所述的内轮外面设有凸块，所述的弹性轮上设有卡槽，所述的内轮通过凸块与弹性轮上的卡槽相套合。
进一步的，所述的锁芯与锁把之间设有锁销并通过锁销带动相互旋转。
与现有技术相比，本实用新型的优点及有益效果：
1.本实用新型产品可找回密码，解决了密码轮容易忘记密码、乱码等问题；
2.本实用新型产品操作简单，只需要插入备用钥匙转动锁芯，转动密码轮直至转不动为止，就可找回正确密码，无其他任何要求；
3.本实用新型产品结构简洁，成本低，并没有增加过多的零件，以及加工工艺复杂的零件，整体组装简单，在原有的基础上，并无过多成本的增加。
