Description
Technical field
The utility model relates to mechanical code lock, relates in particular to the mechanical code lock of inputting simultaneously password by key.
Background technology
In order to improve the security performance of mechanical lock, Cipher mechanism is set in mechanical lock, only have the correct rear lock of Password Input to be opened by machinery.
Existing mechanical code lock has the following disadvantages:
First is not enough to be to open the mode of password for to input by turn by button or roller.Convenience during the slow and input password of the speed of input password is poor; The button that the input password is used and roller are on lock panel, and the core components such as cipher wheel appear on the panel corresponding, and code component is easily destroyed, poor stability; Need to remember password, very inconvenient when coded lock use amount crowd large and poor memory uses.
Number be 2011103846155 in Chinese patent application, date of publication be February 29 in 2012 day, be called in the patent documentation of " a kind of cryptographic key and lock " and disclose a kind of mechanical lock.This lock just is combined in cylinder lock and coded lock in the opening device, belong to paralleling model.Fail to solve Password Input and the problems referred to above that arrange, and should be cylinder lock on the stricti jurise, do not have the safety of coded lock.
Second deficiency is: input password and unblank to finish by two mechanisms by key or handle does not integrate.
The 3rd deficiency is: existence can be by the deficiency of technical opening.Existingly know that the technological means (hereinafter referred to as the means of decoding) of password has three kinds: the first is for knowing by the inner Cipher mechanism of ray scanning lock; The second is known for spying on the slit between the lock housing by the peep hole of using from the observation password; The third is by carrying out unlocking action, (principle of mechanical cipher is by password groove and the code pins that complements one another is set between cipher wheel and lock pin to make password unit be in the comparison state, password groove and the code pins one in the two is mobile together in company with lock pin, when the password groove aligns with code pins then lock pin can move into place, this moment the dead bolt mechanism that just can be unlocked open, when if the password groove staggers with code pins, then lock pin can not move into place, dead bolt can not be unlocked at this moment.The comparison state refers to lock and is in the course of action of opening and cipher wheel has hindered the state in further when operation of lock pin), then make by Password Input mechanism and drive the driving wheel rotation that cipher wheel is rotated, driving wheel drives cipher wheel, and to turn to correct password position be that the password groove is when aliging with code pins, then can hear the motion and sound of alignment or the minor variations of perception lock pin position, thereby learn password.Below the third means of decoding are called mechanical comparison method.The first means of decoding can be by arranging layer cracking of preventing that ray from passing in lock; Second means of decoding can be carried out the mode that view mode maybe is designed to lock not need to observe password to password and crack by being changed; And for mechanical comparison method, still lack at present effective and do not affect the crack method of the normal use of lock.
Be 2008100700431 in China Patent No., open day be December 17 in 2008 day, be called in the patent documentation of " with the rotary mechanical puzzle lock of measuring-proof apparatus " and disclose a kind of mechanical code lock.This lock mainly comprises axis of rotation (being equivalent to driving wheel), with the active cipher wheel that is connected together by fixture block between the axis of rotation, be successively set on some driven cipher wheel on the cipher wheel initiatively, the password groove inserted block and the V shape that link together with lock pin carve plate, all cipher wheel are provided with slot.The method that this mechanical code lock cracks mechanical comparison method is: in the process of the radially close initiatively cipher wheel of password groove inserted block, before password groove inserted block abuts to the active cipher wheel, it is that fixture block is not stuck on the active cipher wheel with the active cipher wheel with throwing off between the rotating shaft that V shape is carved plate, so that rotating shaft can not drive initiatively cipher wheel rotation, thereby crack mechanical comparison method.Although this lock provides a kind of form of structure that mechanical comparison method is obtained password that cracks, but this form of structure has the following disadvantages: no matter be normal comparison (comparison when password is correct) and improper comparison (comparison during password bad), all can throw off between the same rotating shaft of cipher wheel (driving wheel), can to cause the drive mechanism between rotating shaft and the cipher wheel be that fixture block produces heel and toe wear in disengagement frequently, causing driving error is that driving wheel (rotating shaft) and the cipher wheel angle of rotating is asynchronous, correct and the phenomenon that lock can't be opened of input password value occurs; If rotating shaft when the comparison state then can change password (due to the not synchronous rotation of cipher wheel), it is then unknown for what specifically to change as for password, also namely can produce the password loss phenomenon, the normal use that impact is locked
The 4th deficiency is: password groove and code pins are the alignment actions of radially comparing along cipher wheel when carrying out the password comparison, being in staggered positions in password groove and code pins namely inputs when carrying out unlocking action under the state of password bad, cipher wheel is subjected to all extruding force radially to cause the shaft bending of cipher wheel to be out of shape, and causes the cipher wheel can not normal rotation even application life stuck, the impact lock.
The utility model content
First purpose of the present utility model aim to provide a kind of user do not need memory cipher, the key-type wheel machine coded lock of password by the disposable input of cipher key, the parts of inputting by turn inconvenience, cipher wheel to solve password are positioned on the surface poor stability that is caused, the problem that needs memory cipher.
Second purpose of the present utility model is intended to improve a kind ofly unblanks and inputs the key-type wheel machine coded lock that password is finished by same key, separately carries out the not compact problem of operation inconvenience and mechanism that caused to solve existing mechanical code lock input password and key unlocking.
The 3rd purpose of the present utility model aims to provide a kind of key-type wheel machine coded lock that can prevent that mechanical comparison method from unblanking and can not produce the password loss phenomenon, lacks effective and do not affect the problem of crack method of the normal use of lock to solve for mechanical comparison method.
The 4th purpose of the present utility model aims to provide a kind of key-type wheel machine coded lock that cipher wheel rotating shaft distortion phenomenon was compared and caused to password that can not produce, can not normal rotation even problem stuck, that affect the application life of lock to solve the cipher wheel that can cause the cipher wheel shaft bending when the existing password of existing mechanical code lock is compared and cause.
Above technical problem solves by following technical proposal: a kind of key-type wheel machine coded lock, comprise unlocking mechanism and lock body, lock body is provided with at least two password units, password unit comprises cipher wheel, the driven wheel that the driving cipher wheel is used and the lock pin that moves together in company with unlocking mechanism, be provided with the code pins and the password groove that complement one another between described lock pin and the cipher wheel, it is characterized in that, also comprise cipher key, described lock body is provided with the cipher key hole, described password unit also comprises the tooth bar that drives driven wheel, and described cipher key is provided with the drive block that is used for driving correspondingly the tooth bar of password unit that quantity equates with password unit quantity.In the use procedure, when cipher key inserts the cipher key hole, the tooth bar that drive block on the cipher key drives all password units correspondingly is translation one segment distance all, the rack drives driving wheel rotates a set angle, driving wheel drives cipher wheel and rotates synchronously, the distance that moves by controlling each toothed rack, make the cipher wheel of the password unit at its place turn to code pins and password groove from the position that code pins staggers with the password groove and be in aligned position (being the correct position of said password on the ordinary meaning), namely realized the Password Input of corresponding password unit.Whether change the conventional password value that passes through to remember password and watch input to controlling the input of password, but also be the angle that code pins staggers with the password groove according to the password value that each password unit sets, when setting key and driving all tooth bars and move, the angle that each tooth bar rotates cipher wheel is consistent with this angle that staggers, and each password (password unit is set a password) all is unlocked so that key can make each password unit all open also when inserting keyhole.Make the unlatching of lock behind the cipher key insertion cipher key hole by unlocking mechanism, can the band pendulum lock pin move together in the process that unlocking mechanism is unblanked, if password bad, then not alignment of code pins and password groove, cipher wheel can hinder lock pin and moved this moment, so that unlocking mechanism can not opened lock.When cipher key is extracted, the counter-rotating of rack drives driven wheel, driven wheel drive the cipher wheel counter-rotating, the counter-rotating of cipher wheel so that code pins stagger with the password groove, be that password is upset again, the wheel of beating of password moves, existing coded lock need to manually go from new rotational password wheel, and this design upsets the action of password and automatically finishes when extracting cipher key.When changing the password (being the angle that staggers of password groove and cipher wheel) of corresponding password unit, as long as the displacement that makes cipher key drive corresponding tooth bar changes to this angle unanimously.When tooth bar was fixed on the cipher key, in the process when then extracting cipher key, tooth bar moved outward, the counter-rotating of rack drives cipher wheel; When tooth bar is arranged in the lock body, then will design resetting-mechanism, in the process that cipher key is extracted, move on to original state outward so that tooth bar is also being followed key, the simplest form of structure of resetting-mechanism is for using spring reset.And the amount of being positioned at of tooth bar is continuous, with respect to existing with numeral show for (centrifugal pump), be equivalent to comma-less code, can't try attitude and go out password by inputting different password values, safety is better.Different in position on the key by setting drive block, so that although the distance that cipher key inserts in the cipher key hole is a fixed range, and drive block drives the distance difference that tooth bar moves, and realize that the displacement of tooth bar is with the angle that staggers consistent (namely can make tooth bar just can make cipher wheel turn to the password groove with the position of code pins alignment) of corresponding code pins and password groove, if when going to drive tooth bar by other object, can not make code pins with the alignment of password groove (not knowing namely how many corresponding passwords is) owing to knowing to move how many distances yet, therefore can't input correct password.
