Description

A kind of key-type mechanical puzzle lock

Technical field:

The utility model relates to a kind of coded lock, particularly relates to a kind of key-type mechanical puzzle lock.

Background technology:

Along with the increase and the growth in the living standard of people's material wealth, people more and more pay attention to home safety, install various security doors and theftproof lock at home one after another.Traditional mechanical lock has been widely used in huge numbers of families, and through updating, its function is quite perfect, and new kind constantly occurs, but they change ten thousand times without leaving the original aim or stand, and still will open the lock with the key.Although it is perfect that traditional mechanical lock has become, it has a defective: but that is not having under the situation of key the people for unblanking yet, and its safety problem is not solved at all, and the owner of lock is losing key or leaving behind under the situation of key and just can't unblank.Mechanical code lock has appearred on the market for addressing these problems.Mechanical code lock in the market, the structure more complicated is used inconvenience, is difficult to be accepted by users, is difficult to promote.

Technology contents:

Technical problem to be solved in the utility model provides a kind of not opening the lock with the key and confidentiality height, simple in structure, cheap key-type mechanical puzzle lock.

The technical solution adopted in the utility model is: in lock body, be fixed with lower wall and on dish, between last dish and lower wall, rotating rotating disk is housed, rotating disk is provided with pull pin corresponding with locking bar, sells, rotating disk is packed on the turning cylinder that has the handle of unblanking; Should be assembled in the slideway that is located in dish, rotating disk, the lower wall by the password pole pair that descends pellet shot from a slingshot, middle pellet shot from a slingshot, last pellet shot from a slingshot to form, the length of middle pellet shot from a slingshot equals rotating disk length, and middle pellet shot from a slingshot material is a permanent magnet, and following pellet shot from a slingshot, last pellet shot from a slingshot material are one of iron, cobalt, nickel; Lower wall is provided with the decipherer of the adjustable position of answering with the password pole pair; Be provided with return spring between last pellet shot from a slingshot and the lock body, last pellet shot from a slingshot front end is provided with digital tooth; Be hinged with on the lock body corresponding with digital tooth be equipped with return spring pull out plate and by the sign indicating number key, " n " shape permanent tooth pin one end that is provided with return spring is corresponding with digital tooth, the other end is corresponding with the ring that resets on being enclosed within turning cylinder; Be provided with rotatable locking closure in the lock body rear end, rotatable lock covers and is provided with the dead man corresponding with locking bar.

Because the utility model has adopted technique scheme, several groups of staggered assemblings of password bar, in use, press corresponding password bar by the sign indicating number key, pull out plate and the acting in conjunction of permanent tooth pin, promote the password bar and travel forward, the numerical value of setting is several, just by several times, right when all pressing by the sign indicating number key of several groups of password bars, corresponding middle pellet shot from a slingshot all enters in the rotating disk, and rotating disk could rotate, pull pin and just can stir locking bar and unblank, along with the increase of password bar group quantity, its security performance is higher, and the user can change password voluntarily, and this apparatus structure is simple, and is cheap.

Description of drawings:

Fig. 1 is the utility model internal construction sectional view;

Fig. 2 is the utility model external structure schematic diagram.

The specific embodiment:

Referring to Fig. 1 and Fig. 2, in lock body 1, be fixed with lower wall 23 and on coil 6, rotating rotating disk 5 is housed between last dish 6 and lower wall 23, rotating disk 5 is provided with corresponding with locking bar 4 pulls pin 17, rotating disk 5 is packed on the turning cylinder 7 that has the handle 14 of unblanking; Be assembled in the slideway 22 that is located in dish 6, rotating disk 5, the lower wall 23 by password bar 21 correspondences of descending pellet shot from a slingshot 2, middle pellet shot from a slingshot 3, last pellet shot from a slingshot 20 to form, the length of middle pellet shot from a slingshot 3 equals rotating disk 5 length, middle pellet shot from a slingshot 3 materials are permanent magnet, and following pellet shot from a slingshot 2, last pellet shot from a slingshot 20 materials are iron; On lower wall 23, be provided with the decipherer 19 of the adjustable position corresponding, be provided with return spring 24 between last pellet shot from a slingshot 20 and the lock body 1, last pellet shot from a slingshot 20 front ends and digital tooth 13 is arranged with password bar 21; Be hinged with on the lock body 1 corresponding with digital tooth 13 be equipped with return spring 10 pull out plate 8 and by sign indicating number key 9, " n " shape permanent tooth pin 11 1 ends that are provided with return spring 12 are corresponding with digital tooth 13, the other end is corresponding with the ring 15 that resets on being enclosed within turning cylinder 7; Be provided with rotatable locking closure 18 in lock body 1 rear end, rotatable locking closure 18 is provided with the dead man 16 corresponding with locking bar 4.

Last dish 6, rotating disk 5, lower wall 23 materials can not be one of iron, cobalt, nickel.

Open rotatable locking closure 18, regulate the decipherer 19 on the lower wall 23, adjust the code number of corresponding password bar 21.In use, press corresponding password bar 21 by sign indicating number key 9, pulling out plate 8 plates point promotion digital tooth 13 advances, permanent tooth pin 11 pins digital tooth 13 simultaneously, whenever click by sign indicating number key 9, pulling out under plate 8 and 11 actings in conjunction of permanent tooth pin, pellet shot from a slingshot 3 is the following pellet shot from a slingshot 2 of iron with material in the permanent magnet, the password bar 21 that last pellet shot from a slingshot 20 the is formed digital tooth pitch that advances, the code number numerical value of setting is several, just by several times, have only several groups of password bars 21 by sign indicating number key 9 all by right, corresponding middle pellet shot from a slingshot 3 all enters in the rotating disk 5, the handle 14 of unblanking could rotate rotating disk 5, and pulling pin of rotating disk 5 17 just can be stirred locking bar 4, just can unblank.

When pushing the wrong when maybe needing to lock, stirring the ring 15 that resets, the ring 15 that resets promotes the digital tooth 13 that permanent tooth pins 11 unclamp password bar 21, and password bar 21 is return under return spring 24 effects, can lock or again button unblank.At the rotatable locking closure 18 of indoor rotation, the dead man 16 on the rotatable locking closure 18 is stirred locking bar 4 and can be unblanked.
