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

4. a key formula is hidden coded 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 all are simple just energy releases of dependence numerical ciphers, if password suffers to reveal just directly release, these are locked in knows under the tangible numerical ciphers situation, the mode of occupation at password does not limit, and its security performance finding is general.

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

Summary of the invention

Under above-mentioned situation, the invention provides a kind of simple in structurely, with low cost and can prevent the mechanical lock that password is revealed, it is with high costs to solve the Current Password lock, and 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 invention is: a kind of anti-mechanical code lock of divulging a secret, in lock body, be provided with and carve type dead bolt and tack dead bolt, and by shaft locking sleeve and the release of combination disk control lock shaft, 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 at the password body, dead bolt interlock 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 the 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 present invention proposes, reliable in structure, use key that both can be simple locks and release in use, also can only operate by numerical ciphers, key cooperates encryption with numerical ciphers after, even obtained under key and the 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 under 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 invention can directly convert in existing common mechanical lock, and this provides the economical and reliable safety guarantee again one time for the user that the standard machinery lock is installed.
