Toward moving right, character wheel core is separated with character wheel, and when character wheel selection password is stirred, character wheel is rotated and character wheel core is not rotated, then
Rotary knob 7 simultaneously drives lock housing 4 to rotate, and closes coded lock, and now, lock housing projection is not abutted with character wheel mandrel, and character wheel mandrel exists
In the presence of 3rd spring 13, the 4th spring 14, character wheel mandrel and character wheel core return to initial position, character wheel core now and character wheel
It is engaged, character wheel can drive character wheel core to rotate together, and the projection on character wheel mandrel is separated with groove, such four passwords are just
It is set, after upsetting code word, when correct password is not found, character wheel core is engaged with character wheel, but the groove of character wheel core
With the projection on character wheel mandrel not on the same line, lock housing is all abutted against with character wheel mandrel, so that lock housing cannot with knob
Rotate.
When fixed central spindle 30 is located at 29 horizontal one end of shifting part, fixed central spindle is no to be abutted against with character wheel core, this when
As common key, who can be turned on or off coded lock to the password for setting according to common key, and can change public
Password, when shifting part is stirred, makes fixed central spindle move up along raised platform 31, fixed central spindle is abutted against with character wheel core,
Character wheel core cannot be moved, and after password is set, cannot just reset password, and the password for setting this when is as private code.
When coded lock is closed, operator forget Password, and lock cannot be opened under normal circumstances, use
Emergency key 35 can find the password of setting.Using correct emergency key, in insertion lock core component 5, rotation lock core assembly,
So as to drive dead bolt 21 to rotate, dead bolt passes lock housing and abuts against with movable plate 20, and movable plate moves right in the presence of dead bolt
Dynamic, so as to by plunger tip 24, the jack-up of top cover 26 in movable plate groove 25, now rotate character wheel, character wheel drives character wheel core, directly
To the groove of the embedded character wheel core of plunger tip, that is, the password of the character wheel is have found, remaining three character wheels are rotated successively, find setting
Password, then according to password unlocking.
When the password for setting is as private code, in unlocking condition, after having dialled disorderly password, operator can be using special
Original password is given for change with key 36, the method for operation inserts lock core component, makes plunger tip be embedded in character wheel with above-mentioned with private key 36
In groove on core, character wheel is set to rotate, the code word at this moment showing is the password of setting.
The lock core component 5 is prior art, and this is no longer going to repeat them.
A kind of coded lock that the present invention is obtained, can be common key and private code by the password setting of coded lock, expire
The demand of foot difference occasions, and can ensure that operator forget or by other user modification new passwords after, can be with
Give password for change and change, it is safe and reliable, it is easy to operate.
