Technical field

The utility model relates to lock core and key thereof, relates in particular to a kind of Magnetic lock cylinder and key thereof.

Background technology

Present its structure of Magnetic lock cylinder used in the prior art is the magnetic marble radial distribution, utilizes the magnetic force of key to make it move radially the open and close of controlling dead bolt.The shortcoming of this structure is easily by pirate of the open, use other implements to make it produce vibrations or mode such as the feel of unblanking by searching is unblanked, simple in structure because of it, also exist a key to open the possibility of many locks, therefore, its safety of existing Magnetic lock cylinder, reliability all need further improvement.

Summary of the invention

The purpose of this utility model provides a kind of safety, good reliability, is difficult for by the novel Magnetic lock cylinder and the key thereof of pirate of the open.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of Magnetic lock cylinder, comprise lock body 1, dead bolt 2, the dead bolt driving mechanism, described dead bolt 2 can be by stretching out vertically in the dead bolt driving mechanisms control self-locking body 1, the described structure of the dead bolt driving mechanism in the closed cylindrical shape lock body 1 that places is: be with spring 3 on the dead bolt 2, the dead bolt 2 afterbodys disk 4 that has been fixedly connected, be fixed with and the backstay 5 that extend back parallel more than 2 on the disk 4 with dead bolt 2 axis, the dead bolt end is stretched out and inserted interior from disk 4 is in the sleeve pipe 7 of keyhole 6, being with diameter outside the sleeve pipe 7 does not wait, a plurality of annulus 8 of making by nonmagnetic substance, there is one to hold the arc notch 9 that backstay 5 passes through respectively on the circumferential edge of described annulus 8, the circular ring-shaped permanent-magnet body 10 that two radial symmetric distribute is installed on the described annulus 8.

As to further improvement of the utility model, described backstay 5 length equalizations, the ladder collar 11 that the end is fixedly connected with backstay 5, inner surface matches with annulus 8 is arranged between backstay 5 and a plurality of annulus 8, axially outstanding projection 12 is arranged on the inner headed face of the described ladder collar 11, the axial tooth 16 of afterbody for axially stretching out, having on each annulus 8 can be with the axial notch 13 of projection 12 or axial tooth 16 embeddings.

As to further improvement of the utility model, described backstay 5 passes the hole on the positioning disk 14 that is fixedly connected between disk 4 and the annulus 8 and with lock body 1.

As to further improvement of the utility model, the quantity of described backstay 8 is three, and the quantity of described annulus 8 equates with backstay 5.

As to further improvement of the utility model, there is banking pin 15 described keyhole 6 entrance.

Described key is made by nonmagnetic substance, when inserting the keyhole state corresponding to each annulus 8 place have radially install, with circular ring-shaped permanent-magnet body 10 opposite polarity key permanent magnets 17.

As to further improvement of the utility model, be provided with the key bit 18 of indication position of rotation after the insertion end of described key.

The utility model is to use like this:

Unblank: key is inserted in the keyhole, ejection dead bolt firmly, make guide peg leave annulus, and screw key, magnetic force on the key rotates annulus, and breach and backstay (or axial notch of projection and annulus) on the annulus are aligned, extract key this moment out, each root backstay simultaneously by the breach of each annulus, drives dead bolt and moves backward under the effect of spring, reaches the purpose of unblanking.

Locking: key is inserted in the keyhole, and the ejection dead bolt of exerting oneself, make guide peg withdraw from the breach (or projection withdraws from the axial notch of annulus) of annulus, each annulus rotates under the mutual magneticaction of key and annulus and is distribution at random, withdraw from key, dead bolt is in locking states.

Key bit and spacer pin are set can be opened and locking more easily.

The beneficial effects of the utility model are: because each magnetic all can be in any setting on the circumference of 360 degree, 10 degree are a different position if whenever be separated by, then the various combination group number of key bit and three magnets is: (360/10) (360/10) (360/10)=46646, reach the ministry standard requirement, increase behind the key bit on the key combination and can reach (360/10) (360/10) (360/10) (360/10)=1679616, effect is better.Can avoid a key to drive many locks; Key can rotate by 360 degree in lock core, does not have perceptible feel, does not also have the sound that helps unblanking that can hear, and theft can't find method for unlocking by seeking feel, sound or other vibration modes, so the purpose of this utility model can realize.
