这是一个密码锁保险箱，为了更好的展示密码锁的工作原理对锁盘部分进行了放大设计。当然他作为一个保险箱的功能是完好的，并且可以自己对密码进行调整。

This is a combination lock safe box, in order to better show the working principle of the combination lock on the lock disc part of the enlarged design.Of course, It's still a safe box and can adjust the password itself.

整体都可以打印，没有额外五金零件，只需要一根耗材连接门和箱体

The whole can be printed, no additional parts, only need a filament to connect the door and the box

1.加强密码盘轴,解决容易断的问题

2.增加了一个紧凑密码的配置

如何修改密码/How to Change Password:

1.先将数字盘指向0，然后逆时针旋转3圈，将密码盘重置到初始位。

Start by pointing the number disk to 0, and then turn counterclockwise 3 times to reset the password disk to the initial position.

2.继续逆时针旋转，直到第一个锁盘缺口对齐立杆，这时数字盘的数字就是第一个密码（图片中是4）

Continue rotating counterclockwise until the first lock disc notch aligns the vertical rod, the number on the dial is the first password (4 in the picture).

3.反向顺时针旋转，直到第二个锁盘缺口对齐立杆，这时数字盘的数字就是第二个密码（图片中为4.3），因为进行反向旋转所以第二个密码记作反 向4.3。

Reverse clockwise rotation until the second lock disc notch aligns the vertical rod,the number of the digital disk is the second password (4.3 in the picture).because of the reverse rotation, the second password is referred to as reverse 4.3.

4.再次反向逆时针旋转，直到最后一个锁盘锁盘缺口对齐立杆，这时数字盘的数字就是第三个密码（图片中为7.8）

Reverse and counterclockwise rotation again until the last lock disc notch the vertical rod, then the number of the number disc is the third password (7.8 in the picture).

5.修改密码只需要改变锁盘上黑色立柱的位置，之后在重复1-4步读出密码。

To change the password, you only need to change the position of the black column on the lock disc, and then repeat steps 1-4 to read the password.

最后，希望这个模型能帮助你了解密码锁的工作原理，还能获得自己组装了一台密码锁的成就感！

Finally, I hope this model can help you understand the working principle of the password lock, but also get the sense of accomplishment of assembling a password lock yourself!
