Description

Anti-theft puzzle lock

Technical field

The utility model relates to a kind of lock, especially a kind of anti-theft puzzle lock.

Background technology

The at present commercially available lock that generally uses with people all is to be made of lock body, lock core and interior pellet shot from a slingshot, spring thereof.Only insert lock core with a key and rotate, making the lock core rear end stir dead bolt in flakes can unblank.This lock construction is simple, and marble row numbers is few, and keyhole exposes in addition, and the very easily stolen tool that goes into operation is opened.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of with password, with many key operated anti-theft puzzle lock.The purpose of this utility model, realize by following technical proposals: lock core is provided with three layers of core retainer plate, and lock core and three layers of core retainer plate are socketed in the lock body, and lock body, core retainer plate, lock core radial equipartition ten row's pellet shot from a slingshot through holes are provided with pellet shot from a slingshot and spring in the hole.The tail end of lock core and three layers of core retainer plate all is provided with external tooth, internal tooth with corresponding combination disk meshes respectively, combination disk all is provided with onesize breach, matches with breach on the lock body, and lock body and lock core are provided with the keyhole of spline, combination disk standing screw body is through in the center of circle of keyhole, form annular dentation keyhole, key is made the sleeve dentation, matches with keyhole, key be equal to or less than that combination disk quantity adapts number, ten numbers of mint-mark on the lock body end face " 0～9 ".

Because the utility model is provided with four combination disk, when the breach of four block encryption dishes all when breach on the lock body aligns, be opening, twist door handle this moment, drive dead bolt and take in the breach, thereby reach the purpose of opening the door.When if as long as the breach of a block encryption dish and the dislocation of lock body breach are arranged, all be locking-in state and turn round motionless door handle.Establish four different marks on the lock core end face, the respective markers of four each contrasts of key oneself is inserted lock core from different directions; Also can only establish a mark on the lock core end face, four keys all insert lock core to mark like this.Teeth groove on the lock body should be convenient to observe the mark on the lock core end face greater than the teeth groove on the lock core, with the direction of determining that key inserts, and guarantees that key can insert or extract at an arbitrary position.Combination disk, core retainer plate (or lock core), key three are one to one, and the user can set any key for any password, promptly 0～9 in any one numeral.The method that is provided with is, key is inserted lock core, turn to the numerical ciphers position that you need, and then the breach on the breach of the combination disk alignment lock body, the internal tooth of combination disk is engaged in the external tooth of this core retainer plate (or lock core), fixing.The order that four key ciphers are set is that the first key of core retainer plate and lock body outside disconnecting finishes to the 4th key that disconnects lock core and inner core cover in turn.

Because the utility model adopts lock core to add three layers of core retainer plate, four layers of password, ten row's pellets shot from a slingshot, sleeve key, the lock body tooth is covered the lock core toothing, so, when unblanking, four keys to be arranged not only, and will remember the password that four keys are set, and, could open according to lock core in turn from outer core retainer plate.The method of opening is: at first insert lock core with the respective markers on the first key alignment lock core end face, at this moment, lock core and three layers of core retainer plate are linked to be integral body by pellet shot from a slingshot, and disconnect with lock body, key is to the password position that sets, lock core and three layers of core retainer plate rotate with key, make the breach on the combination disk breach alignment lock body on the outer core retainer plate, take out key; Insert lock core with second key alignment respective markers again, this moment, pellet shot from a slingshot fused lock body and outer core retainer plate, middle core retainer plate, inner core cover, lock core fuse, outer core retainer plate and middle core retainer plate disconnect, the password position that key sets to this key, make intermediate core put the combination disk breach alignment lock body breach of engagement, take out key; Equally, the 3rd key inserts, and core retainer plate, outer core retainer plate and lock body are linked to be integral body in the middle of making, and inner core cover turns to the password position that sets with lock core, and the combination disk breach alignment lock body breach on the inner core cover takes out key; At last, alignment mark inserts the 4th key, and at this moment, three layers of core retainer plate and lock body are linked to be integral body, and disconnects with lock core, and key is to set password position, drive lock core and on combination disk breach alignment lock body breach, take out key, finish and unblank.At this moment, the breach of four block encryption dishes all aligns with breach on the lock body, is in opening, turns door handle, drives dead bolt and retreats in the combination disk breach, can realize opening the door.

If the user need simplify the process of unblanking, then can set the state that only can open for a key, in the present embodiment, also can set for must be with two or three multiple schemes that key is opened.Method is: be at lock under the state of complete opening, can pin and open with any key, other three keys need not get final product; Be at lock under the state of complete opening, also can pin and open with any two keys, two keys in addition need not get final product; The rest may be inferred by analogy, promptly as long as with the pairing combination disk breach alignment of no key lock body breach, be in opening and get final product.

From above-mentioned situation as can be known, the purpose of this utility model can realize.Compared with prior art, have multiple anti-theft feature: the one, have cryptographic function, light has key, does not have password, is difficult to open; The 2nd, many keys function, many keys, indispensable; The 3rd, the order of unblanking function, key is complete, also knows password, does not also drive lock if know opening sequence; The 4th, many row's pellet shot from a slingshot functions, the pirate of the open instrument is difficult to the depth of tens of explorations even a hundreds of pellet shot from a slingshot; The 5th, multilayer core retainer plate function even the pirate of the open technology is very brilliant, disconnects certain one deck pellet shot from a slingshot, also can't disconnect layer by layer, does not know the direction of breach alignment still more, and this turns to and where stops; The 6th, ring profile of tooth keyhole, the pirate of the open instrument is difficult to enter; The 7th, the lock body tooth is covered the lock core tooth, the pirate of the open instrument of insertion can't be rotated, thereby play antitheft effect.The utility model is specially adapted to important door locks such as the safety cabinet, national treasury, arm store of many people management.
