Abstract

The utility model discloses a magnetic lock. The magnetic lock comprises a lock cylinder, a lock sleeve, first marbles and magnetic marbles, wherein the lock cylinder, the lock sleeve and the first marbles are all made of non-magnetic materials, and the magnetic marbles are permanent magnets. A groove is formed in the portion outside each marble hole of the lock cylinder along the axis of the marble hole, and a hole strip is embedded in each groove. Each marble hole of the lock cylinder is provided with one first marble, and each hole strip and each marble hole of the lock sleeve are respectively provided with one magnetic marble. The contacting face of the hole strips of the lock cylinder and the lock sleeve is located between the upper surfaces of the magnetic marbles and the lower surfaces of the magnetic marbles. A magnet is arranged on a key at the position corresponding to the marble holes, and the magnetic poles of the lower faces of the magnetic marbles in the marble holes are the same as the magnetic pole of the opposite face of the corresponding magnetic on the key. The magnetic lock has strong anti-theft ability.

Description

Magnetic lock

Technical field

The utility model relates to lock technology field, relates in particular to magnetic lock.

Background technology

Because common mechanical lock theftproof is relatively poor, and theftproof is locked preferably, its structure is often too complicated, and magnetic lock is shown up prominently gradually because of novel structure.Yet general magnetic lock is too simple, and theftproof is also relatively poor.

Summary of the invention

In order to solve the existing above-mentioned deficiency that is latched in, the purpose of this invention is to provide a kind of theftproof and lock preferably.

The utility model magnetic lock comprises lock core, lock tube, and first pellet shot from a slingshot is all made of non-magnet material, and magnetic bullet is a permanent magnet; Lock core is loaded in the lock tube and can rotates, and lock core has a keyhole, and lock core one side has a plurality of pellets shot from a slingshot hole, and lock tube is to there being the pellet shot from a slingshot hole.The outside at the lock core marble hole place, have a groove along its axis, and in groove, inlay a root hole bar, this hole bar is made of non-magnet material, its width also has the pellet shot from a slingshot hole of same quantity greater than the pellet shot from a slingshot bore dia of lock core on the bar of hole, its diameter is less than the pellet shot from a slingshot bore dia of lock core, the pellet shot from a slingshot bore dia of lock tube is identical with the pellet shot from a slingshot bore dia of hole bar, the corresponding pellet shot from a slingshot hole coaxial line of lock core, lock tube and hole bar; The height of first pellet shot from a slingshot is less than the distance between the soffit of bottom surface to the hole bar of lock core marble hole, its diameter is greater than the pellet shot from a slingshot bore dia of hole bar, in each pellet shot from a slingshot hole of lock core one first pellet shot from a slingshot is housed, adorn a magnetic bullet in the pellet shot from a slingshot hole of each hole bar and lock tube, spring piezomagnetism pellet shot from a slingshot also contacts with first pellet shot from a slingshot, make the bottom surface of first pellet shot from a slingshot to the pellet shot from a slingshot hole of lock core, pellet shot from a slingshot all can move in corresponding pellet shot from a slingshot hole, and the hole bar on the lock core and the cross surface mutually of lock tube are between the upper surface and soffit of magnetic bullet; With corresponding position, pellet shot from a slingshot hole magnetic patch is arranged on the key, the magnetic below the magnetic bullet in pellet shot from a slingshot hole is identical with the opposite face magnetic of corresponding magnetic patch on the key.

As improvement of the present utility model, magnetic lock has at least in the pellet shot from a slingshot hole of a hole bar and lock tube two second pellets shot from a slingshot is housed, and has at least in the pellet shot from a slingshot hole of a hole bar and lock tube a magnetic bullet is housed.

When the key of the utility model magnetic lock inserted lock core, the key top promotes first pellet shot from a slingshot ultimate range that moves up can only make its upper surface contact with the soffit of hole bar at the most.

Because the utility model magnetic lock has adopted non magnetic pellet shot from a slingshot to combine with magnetic bullet, in the key insertion nonmagnetic first pellet shot from a slingshot is moved, thereby magnetic bullet is also moved, but this moment the hole bar on the lock core with the cross surface mutually of lock tube still between the upper surface and soffit of magnetic bullet, lock core can not rotate relative to lock tube.Only corresponding to place, pellet shot from a slingshot hole magnetic patch is set at key, according to the identical and mutual repulsion of the magnetic of magnetic patch top and magnetic bullet bottom, make on the magnetic bullet and move, at this moment the hole bar on the lock core and the cross surface mutually of lock tube are at the soffit of magnetic bullet and the gap location between the non magnetic pellet shot from a slingshot upper surface, no longer relatively rotate between jam lock core and the lock tube, just can unblank.And the magnetic pole of the magnetic bullet in each round is equipped with variation.This should mechanical movement again magnetic action pellet shot from a slingshot is moved, increased anti-theft capability, and simple in structure.Improved procedure particularly of the present utility model has the pellet shot from a slingshot of a pure mechanical lock at least, except finishing above work, also must add the unlatching of a mechanical billiard when unblanking, and has further increased anti-theft capability.Thereby the utlity model has stronger anti-theft capability.
