Description
Technical field
The utility model relates to a kind of lockset, specifically is a kind of immutable lock for safe deposit box.
Background technology
Traditional lockset often all is with opening different locks with different keys, like this, in case this key is lost, this lock just may be found people's cover of key and be opened, and occasion such as the lock for safe deposit box of placing some valuables often need be taken care of jointly by different people, like this, traditional lockset obviously can not satisfy the demand of common keeping.
The utility model content
The technical problems to be solved in the utility model is that a kind of safe and reliable immutable lock for safe deposit box is provided.
Technical solution of the present utility model is, a kind of immutable lock for safe deposit box with following structure is provided, it comprises locking closure, lock, lock core, dead bolt, multi-disc tooth sheet and key, the base plate inboard of described lock is provided with an axle, described multi-disc tooth sheet superposes successively and is linked on the axle through the axis hole gap, the free end of the spring leaf of every tooth sheet is against on the lock, described locking closure and lock are fixed, described locking closure is provided with the sleeve of epirelief, described lock core is positioned at sleeve, described lock core is provided with keyhole, described dead bolt is installed in the dead bolt hole of lock bottom, described lock core bottom is provided with the device that can stir dead bolt and then dead bolt be advanced or go out, described key comprises master key and divides key, described multi-disc tooth sheet comprises that a slice cardinal teeth sheet and multi-disc divide the tooth sheet, the axis hole of described cardinal teeth sheet is a mounting hole, described cardinal teeth sheet is provided with open slot by an end of dead bolt, and the master key height corresponding with the cardinal teeth sheet behind the keyhole of insertion lock core is provided with the tooth that can stir the cardinal teeth sheet; The axis hole of every branch tooth sheet is circular hole, every branch tooth sheet leans on an end of dead bolt to be equipped with open slot, insert the tooth that is equipped with the branch tooth sheet that can stir this height on branch key behind the keyhole of the lock core height corresponding with every branch tooth sheet, the inner of described dead bolt is provided with the interior projection of open slot that can stretch into cardinal teeth sheet and branch tooth sheet.
After adopting above structure, the immutable lock for safe deposit box of the utility model compared with prior art has the following advantages:
People insert master key the keyhole of lock core earlier, rotate master key, drive dead bolt and in lock, move and stir simultaneously the cardinal teeth sheet, because the axis hole of cardinal teeth sheet is a waist shape, so the cardinal teeth sheet can be to the direction motion away from dead bolt when swaying, backward rotation master key again, cardinal teeth sheet backward rotation and move under the spring leaf effect to the dead bolt direction, make the open slot inward flange of cardinal teeth sheet and the projection edge of dead bolt be close to, promptly this moment the cardinal teeth sheet open slot over against the projection of dead bolt, but the open slot of this time-division tooth sheet is not over against the projection of dead bolt;
Extract master key out, the keyhole and the rotation that will divide key to insert lock core then, make every branch tooth sheet all sway, and then the open slot that makes every branch tooth sheet also is right against the projection of dead bolt, at this moment, cardinal teeth sheet and all open slots of dividing the tooth sheet are all over against the projection of dead bolt, and then make the projection of dead bolt insert the cardinal teeth sheet and divide in all open slots of tooth sheet, be that dead bolt is stirred by a minute key and entered lock, this lock is opened fully;
Reverse rotation divides key, and cardinal teeth sheet and branch tooth sheet reset under spring action, and dead bolt protrudes from lock, the locking again of this lock.
By above dynamic process as can be known, this lock needs to use master key to re-use the branch key earlier and lock could be opened, promptly to possess two keys and just can open lockset, like this, even wherein losing of a key occur, the people who picks up key also can't overlap unlocking tool, and two the people be in charge of a slice key separately, key is gathered just and can be unblanked, satisfied the demand of common keeping, so safer, more reliable.
As improvement, the tooth sheet was six in described minute, and described cardinal teeth sheet is superimposed upon the 3rd branch tooth sheet top, like this, can more increase safety and crypticity so that the profile of tooth complexity of key strengthens the difficulty of prying open lockset.
