Description

Magnetic anti-theft lock and key thereof

Technical field

The utility model relates to the improvement of lock, and particularly a kind of magnetic anti-theft lock and key thereof belong to door lock and annex thereof.

Background technology

Existing lock is mostly opened different locks with different keys, like this in some personal management's occasion, as a plurality of showcases in a plurality of switchboards of a plurality of file cabinets of archives (chamber), electric industry department or power supply box, exhibition hall or the like, each administrative staff must take care of and carry a big string key, to open and close each all locks respectively; The occasion that also has is that an identical key can be opened all locks, and for example each door lock on the railway carriage can be easy to open doors all on the train with the same key that is easy to prepare, and theftproof is poor.

Summary of the invention

The purpose of this utility model is a kind of uniqueness simple in structure to be provided, to be highly versatile theftproof is good again magnetic anti-theft lock and key thereof at above-mentioned deficiency.

The realization the technical solution of the utility model is:

This magnetic anti-theft lock and key thereof, lock body and key that the dead bolt of being stirred by lock tube, lock core, lock core constitutes are formed, and are characterized in:

Lock core in the described lock body is arranged in the lock tube, and the front end of lock core is provided with tapered end, is provided with sliding shoe in lock core, main permanent magnet is housed in sliding shoe, have deep-slotted chip breaker on sliding shoe, in the rear end of lock core secondary permanent magnet is housed, the end of lock core is connected with dead bolt; On lock core, have the pellet shot from a slingshot hole, on the lock tube of pellet shot from a slingshot hole correspondence, have the pellet shot from a slingshot pilot hole, in the pellet shot from a slingshot hole, pellet shot from a slingshot is housed;

Described being provided with on the key and the corresponding lock nut of tapered end shape is equipped with permanent magnet in lock nut.

Between the end of lock core and dead bolt, also can be provided with interlinked mechanism.

The height of pellet shot from a slingshot should be slightly larger than the wall thickness of lock core in the utility model, and pellet shot from a slingshot makes lock be in closed condition when being stuck in the pellet shot from a slingshot pilot hole; After key inserts the lock core tapered end, main permanent magnet in permanent magnet in the key and the sliding shoe interacts sliding shoe is moved, when the deep-slotted chip breaker of sliding shoe moves to the pellet shot from a slingshot below, pellet shot from a slingshot falls in the deep-slotted chip breaker in main permanent magnet magnetic force effect, leave the pellet shot from a slingshot pilot hole and make lock be in open mode, stir the dead bolt rotation thereby the turn key can drive the lock core rotation; Take off key when the key counter-rotating drives after dead bolt resets, main permanent magnet moves sliding shoe under the interaction of secondary permanent magnet round about, with the pellet shot from a slingshot pop into position, makes lock be in closed condition again by the deep-slotted chip breaker effect.

The utility model uniqueness simple in structure can be opened all locks of the magnetic identical set that is complementary with it with same key, but with not with lock body in other key of being complementary of magnetic just can't open these locks.Have simple in structure, cost is low, processing and fabricating is easy, easy to install, advantage such as reliability height, long service life, highly versatile, theftproof are good.Can be widely used in multiple occasions such as various vehicles, electric industry, postal service, archives, museum, have great promotional value.

The specific embodiment

The utility model is further described with the embodiment that provides below in conjunction with accompanying drawing.

With reference to accompanying drawing, what present embodiment provided is a magnetic tension theftproof lock and key thereof, is made up of lock cylinder 1 and key 30.Lock core 3 in the lock body is arranged in the lock tube 2, the front end of lock core is provided with triangle tapered end 18, is provided with sliding shoe 7 at the in-core of lock core, and main permanent magnet 4 is housed in the inside of sliding shoe, correspondence has 2 deep-slotted chip breakers 19 on sliding shoe, and secondary permanent magnet 5 is housed in the rear end of lock core.Correspondence has 2 pellet shot from a slingshot holes 20 on lock core, has 2 pellet shot from a slingshot pilot holes 21 on the lock tube of pellet shot from a slingshot hole correspondence, and hoodle 6 is housed respectively in the pellet shot from a slingshot hole.End at lock core is connected with outer bush 10 through stirring post 23, and guide pin bushing 11 in the inside of outer bush socket one, in the inside of interior guide pin bushing screw rod 17 are housed, and the inner of screw rod is connected with interior guide pin bushing through bearing pin 9, and the two ends of bearing pin are arranged in the chute 22 of outer bush.Between the inner of screw rod and secondary permanent magnet, stage clip 16 is housed, is fixedly connected with dead bolt 13 in the outer end of screw rod.

Key 30 is provided with and the corresponding recessed triangle lock nut of being made by permanent magnet 32 31 of tapered end shape, is added with sheath 34 outside lock nut.

The magnetic direction of the permanent magnet of present embodiment, main permanent magnet, secondary permanent magnet is arranged and is followed successively by S-N, N-S, S-N, also can be N-S, S-N, N-S.The slightly larger in diameter of hoodle is in the wall thickness of lock core, state as shown in Figure 1, and hoodle was stuck in pellet shot from a slingshot pilot hole inner end and blocked lock core this moment, and lock is in closed condition.After key inserts tapered end, main permanent magnet in permanent magnet in the key and the sliding shoe repels mutually moves to right sliding shoe, when the sliding shoe deep-slotted chip breaker moves to the hoodle below, hoodle falls into deep-slotted chip breaker rapidly under main permanent magnet magnetic attracts, make hoodle break away from pellet shot from a slingshot pilot hole inner end, lock is in open mode.At this moment the turn key rotates lock core in the counterclockwise direction, the post 23 of stirring of lock core was stirred the outer bush rotation when lock core rotated, bearing pin is moved along the downward right of the chute on the outer bush, with reference to Fig. 2, screw rod moves right and clockwise direction rotation simultaneously thereby drive, thereby dead bolt 13 is rotated along clockwise direction.When closing locking, with key to the clockwise direction turn, thereby lock core drives the outer bush counter motion and makes the dead bolt backward rotation, withdraw from key when being rotated in place, at this moment main permanent magnet and secondary permanent magnet repel mutually, sliding shoe is moved to the left the hoodle pop into position in the deep-slotted chip breaker, and lock is in closed condition again.

This magnetic anti-theft lock can be opened all identical locks of inner permanent magnetic body configuration with a key, makes the manager only be equipped with a key, just can easily open all locks that he managed rapidly.Simultaneously, if other people key does not match with the configuration of inner permanent magnetic body, just can't open lock.This key is not easy preparation, high safety.The utility model designer implements one group of magnetic tension theftproof lock by the foregoing description, through the inner trial effect ideal of electric industry department, is subjected to the trier and welcomes.
