3. the revolving dial formula coded lock of a spring compression type, granted patent number is CN102535974A, CN202324863U, CN201915711U, it utilizes central axis to run through multiple drive disc mechanism of setting, and compress driver plate with spring mechanism and frictional force is provided, centered by its releasing process, the axially-movable of axle switches corresponding recessed of driver plate and takes turns breach, makes central axis realize the process of locking and unblock.The axis of this lock is run the cam mechanism very easily caused above and under spring action dislocation inclination is occurred, and makes cam notch to align and to cause unlocking unsuccessfully.

4. a keyed hidden cipher lock, granted patent number is CN202266105U, with multiple revolving dial formula coded lock, granted patent number is CN201825003U, CN201056917Y, CN202152570U, these coded locks are all that simple dependence numerical ciphers just can unlock, and just can directly unlock, under these are locked in and know obvious numerical ciphers situation if password suffers to reveal, mode of occupation not for password limits, and its security performance finding is general.

In sum, in current existing encryption lock, there is cost high, during use, external environment condition requires defect that is harsh and heavy dependence, in some coded lock, in unlocking structure, existing defects very easily causes unlocking unsuccessfully simultaneously, moreover not to the requirement of expressing in use when numerical ciphers unlocks in mode of operation in existing encryption lock, this causes the security performance of coded lock and has a strong impact on.

Summary of the invention

Based on when above-mentioned, the invention provides the mechanical lock that a kind of structure is simple, with low cost and can prevent password from revealing, solve Current Password lock with high costs, the problems such as structure unauthorized unblock behavior that is unreliable and that carry out after cannot preventing password from revealing.

Design scheme of the present invention is: a kind of anti-mechanical code lock of divulging a secret, be provided with in lock body and carve type dead bolt and tack dead bolt, and control lock shaft unblock by shaft locking sleeve and combination disk, lock shaft end is provided with moving runner, can drive moving runner that password is set at password body by rotating lock shaft, password body is provided with code-bar bayonet lock and dead bolt bayonet lock, tongue linked plate code-bar bayonet lock with control under the cooperation of dead bolt bayonet lock to carve type dead bolt and tack dead bolt, it is protruding with lock collar in linkage door that moving runner is provided with moving runner.Password body is made up of rectangular patch code-bar, and its length is 2 ~ 5 times of moving runner external diameter girth.

A kind of anti-mechanical code lock of divulging a secret that the present invention proposes, structure is reliable, use key that in use both can be simple carries out locking and unblock, also can operate by means of only numerical ciphers, after key to coordinate with numerical ciphers and encrypts, even if under obtaining key and password situation, do not understand that the mode of unblanking still cannot unlock.Correct mode of unblanking, can be understood as a kind of private mark of broad sense, this door lock plain code is revealed and key is stolen when also can play antitheft effect, this is for the safety of coded lock, is a kind of to improve significantly.In addition, realization of the present invention directly can convert in existing common mechanical lock, and this is for installing the user of standard machinery lock, further provides once economy reliable safety guarantee again.
