Description

Puzzle spring lock core

The utility model relates to a kind of burglary insurance door lock, particularly safe, antitheft, the insurance password night lock heart of unblanking with password figure.

Existing dual fail-safe pin tumbler lock be utilization activity pellet shot from a slingshot core and fixedly pellet shot from a slingshot carrier interlocking principle and unblank and locking.When unblanking, the pellet shot from a slingshot core is by the control of the breach on the specific mechanical key sheet door lock residing position of being hit by a bullet, after key inserts lockhole, movable pellet shot from a slingshot core and fixedly the interlocking of pellet shot from a slingshot carrier be disengaged, key drive activity cylinder lock transmission bar in the heart rotates the control dead bolt flexibly and unblanks, this class door lock changes limited because of key sheet breach, be easy to illegally to join key and unblank, safety is not strong, simultaneously, people do not note often leaving behind easily and losing key slightly, cause many troubles, existing password night lock adopts lever principle, and feel reaction and slight sound are arranged when unblanking, be easy to cover yet and unblank, safety is not strong.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple in structure, easy to manufacture, with low cost, safe antitheft that has improved, the password night lock heart of unblanking with password figure without key are provided.

Solution of the present utility model is: the password night lock heart is by movable pellet shot from a slingshot carrier, the turn-knob of unblanking, cipher chips, opening cage ring, Active Unlocking circle, passive lock opening ring, unlock chip, fixedly pellet shot from a slingshot carrier, pellet shot from a slingshot group, marble pressuring spring, opening shaft stage clip, fixing card, cover plate etc. constitute.

The password night lock heart of the present utility model is to replace the key sheet with one group of cipher chips, each cipher chips is controlled one group of pellet shot from a slingshot, the cipher chips circumference has many breach, but have only a breach after pellet shot from a slingshot falls into breach, could remove the pellet shot from a slingshot group to the movable pellet shot from a slingshot carrier and the fixing interlocking of pellet shot from a slingshot carrier, have only after this group cipher chips has all been removed the interlocking of two pellet shot from a slingshot carriers of pellet shot from a slingshot group, movable pellet shot from a slingshot carrier could drive the unlock chip rotation and unblank.The breach numeral of unblanking on this group cipher chips is the unlocking cipher of this core, this shows, breach number on cipher chips number and the cipher chips circumference is many more, pellet shot from a slingshot group number is just many more, the probability of unblanking is opposite just more little, safety performance is also just strong more, this core pin design sheet number is 4, the cipher chips circumferential notch is 12, calculates by this assembled arrangement, the probability of unblanking is 20,000/, if unblank once is one minute, opened continuously in one day 24 hours exactly, also need the 14 talentes probability of once unblanking, as seen the safety performance of this core is strong especially.

That the utility model compared with prior art has is simple in structure, easy to manufacture, with low cost, applied widely, without characteristics such as key, easy to use, password unlocking, security insurances.

What the password night lock heart of describing in Fig. 1 to Fig. 7 had that a centre by metal material round steel processing is drilled with the movable pellet shot from a slingshot carrier 1 in necking down round vase type hole and round steel processing is drilled with the onesize eccentric orfice of movable pellet shot from a slingshot carrier 1 round vase type hole outside diameter and the fixing fixedly pellet shot from a slingshot carrier 13 in pellet shot from a slingshot hole, the front of movable pellet shot from a slingshot carrier 1 is provided with an O line, be carved with the cipher chips breach along the O wire loop and count number 0-11, be drilled with four movable pellet shot from a slingshot holes on the pipe wall, afterbody has draw-in groove 2, in the round vasiform orifice of movable pellet shot from a slingshot carrier 1, the turn-knob 3 of unblanking is housed, one group of four cipher chips 5, opening cage ring 8, Active Unlocking circle 9, passive lock opening ring 11, unlock chip 12, the cylindrical turn-knob 3 of unblanking of round steel processing is suspended in the outer end of core and can be used as the handle that opens the door, be provided with an O line on its cylinder equally, be carved with the spacing distance scale of cipher chips 5 along the O straight line, an end afterbody that is contained in the core is provided with turn-knob card 4, tail end face is provided with "-" shape lug card, cipher chips 5 is processed into annular breach circle by steel sheet, the interior circle of each cipher chips 5 is provided with lug 6, excircle is provided with 12 movable pellet shot from a slingshot annular breach 7, but after having only a breach to fall into movable pellet shot from a slingshot, could remove the interlocking of pellet shot from a slingshot group, the center of Active Unlocking circle 9 is provided with cross bath 10, the excircle of passive lock opening ring 11 is provided with convex clip, unlock chip 12 is contained in the center of passive lock opening ring 11, movable pellet shot from a slingshot carrier 1 is enclosed within the eccentric orfice of fixing pellet shot from a slingshot carrier, turn-knob 3 rotates to lockset position of coupler with the annular breach 7 on the cipher chips 5 by unblanking, movable pellet shot from a slingshot carrier 1 is alignd with fixing two O lines of pellet shot from a slingshot carrier 13, load onto pellet shot from a slingshot group 14, marble pressuring spring 15, with tin or the stifled good equating pellet shot from a slingshot hole of aluminium, refill upper shed axial compression reed 16, fixing card 17, at last cover plate 18 is embedded in the circular groove of fixing pellet shot from a slingshot carrier 13, constitute a complete password night lock heart.

The password night lock heart of the present utility model both can with the existing general supporting use of pin tumbler lock, can use separately again, if supporting use, as long as original pin tumbler lock core is changed this password night lock heart, if use separately, then need the master of this password night lock, passive lock opening ring, dead bolt of the supporting design of unlock chip and keeper can be made the coded lock that single-direction and dual-direction such as strongbox, secret chamber, warehouse, drawer, door lock are unblanked.

When unblanking, at first (suppose that the cipher chips spacing distance is 2 by the spacing distance of cipher chips 5, unlocking cipher is 8693) turn-knob 3 of will unblanking advances 2 lattice by the spacing distance scale of O line in core, clockwise rotating the turn-knob 3 of unblanking by unlocking cipher first number 8 again makes the O line of turn-knob align with 8, and the turn-knob 3 of will unblanking advances 2 lattice, clockwise rotating the O line that makes on the turn-knob 3 by unlocking cipher second number 6 again aligns with 6, the rest may be inferred, unlocking cipher 9 and 3 pairs are good, turn-knob 3 propellings 2 lattice will unblank then again to Active Unlocking circle 9, "-" shape card of turn-knob 3 tail ends is inserted in arbitrary groove of " ten " font groove 10, unblank this moment turn-knob 3 just can drive activity pellet shot from a slingshot carrier 1 and unlock chip 12 rotate and unblank, during locking, the rotation turn-knob 3 of unblanking, movable pellet shot from a slingshot carrier 1 is alignd with fixing two O lines of pellet shot from a slingshot carrier 13, withdraw from the turn-knob 3 of unblanking, and dial random cipher chips password and get final product.

It should be noted that advancing and withdrawing from the process of the turn-knob 3 of unblanking, stop, after should the inhour rotation avoiding, push ahead again or withdraw from as lug 6 in the circle in the cipher chips 5, can't be clockwise.
