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 a plurality of driver plate mechanism of setting, and compress driver plate and frictional force is provided with spring mechanism, centered by its releasing process, the recessed breach of taking turns corresponding to driver plate switched in the axially-movable of axle, makes central axis realize the process of locking and release.The axial operation of this lock very easily causes top cam mechanism under acting force of the spring and dislocation occurs tilts, and makes cam notch to align and cause the release failure.

4. key formula hidden cipher lock, granted patent number is CN202266105U, with a plurality of revolving dial formula coded locks, granted patent number is CN201825003U, CN201056917Y, CN202152570U, these coded locks are all simple just energy releases of dependence numerical ciphers, if just password suffers to reveal directly release, these are locked in knows in obvious numerical ciphers situation, the mode of occupation for password does not limit, and its security performance finding is general.

In sum, in at present existing encryption lock, exist cost high, during use, external environment condition requires the harsh and serious defective that relies on, exist simultaneously defective very easily to cause the release failure in some coded lock in unlocking structure, moreover, the not requirement on mode of operation when expressing the numerical ciphers release in use in existing encryption lock, this security performance to coded lock causes and has a strong impact on.

Summary of the invention

In above-mentioned situation, it is a kind of simple in structure, with low cost and can prevent the mechanical lock that password is revealed that the utility model provides, solve the Current Password lock with high costs, structure is unreliable and can't prevent the problems such as unauthorized release behavior of carrying out after password is revealed.

Design scheme of the present utility model 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 the lock shaft release by shaft locking sleeve and combination disk, the lock shaft end is provided with moving runner, can drive moving runner by the rotation lock shaft and at the password body, password is set, be provided with code-bar bayonet lock and dead bolt bayonet lock on the password body, the tongue linked plate is controlled under the cooperation of code-bar bayonet lock and dead bolt bayonet lock and is carved type dead bolt and tack dead bolt, and moving runner is provided with the moving runner projection with lock collar in linkage door.The password body is made of rectangle sheet 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 utility model proposes, reliable in structure, use key that in use both can be simple locks and release, also can only operate by numerical ciphers, coordinate encryption with numerical ciphers at key after, even obtained in key and password situation, do not understand that the mode of unblanking still can't carry out release.The correct mode of unblanking can be understood as a kind of private mark of broad sense, and this is for also playing antitheft effect in the situation that the door lock plain code is revealed and key is stolen, and this is a kind of significant raising for the safety of coded lock.In addition, realization of the present utility model can directly convert in existing common mechanical lock, and this provides once not only economical but also safety guarantee reliably for the user that the standard machinery lock is installed.
