Abstract

The utility model relates to a magnetic lockset. At least two pin tumbler holes formed by blind holes on an inner lock core and accommodation holes on an outer lock core through butting are arranged on a lock core; and the pore diameter of each accommodation hole is smaller than that of the corresponding blind hole; a return spring, a T-shaped pillar sliding in the pin tumbler hole and a magnetic pillar only capable of sliding in the blind hole is sequentially arranged from the small cross section end to the big cross section end of each pin tumbler hole; and a magnet block corresponding to the magnetic pillar in each pin tumbler hole is arranged on a key. When the key is placed in a right unlocking position, each magnet block corresponds to the magnetic pillar in position respectively, and the magnet poles on the opposite surfaces of the magnet block and the magnetic pillar are the same, so that the repulsive force between the magnet block and the magnetic pillar is big enough to completely push the T-shaped pillar butted with the magnet block and the magnetic pillar into the accommodation hole; and when lockout is carried out, all the magnetic pillars are flipped to the bottoms of the blind holes through the return springs, so that the T-shaped pillars form braking at the interfaces of the inner and the outer lock cores. The magnetic lockset has low mutual opening rate, the internal information and the structure of the lock core are not easily detected, so that the sneaking unlocking can be effectively avoided, the use is safe and reliable, and the popularization and the application of the magnetic lockset are facilitated.

Description

Magnetic lock

Technical field

The utility model relates to a kind of lockset, is specifically related to a kind of magnetic lock.

Background technology

In the existing mechanical lock core, single face pellet shot from a slingshot branch narrow range the earliest, and have foozle, be easy to be pushed aside by the people.The cross lock that occurs subsequently then because the keyhole shape of key decision is stressed easily, is easy to the person of being unlocked and opens with the violence of high strength instrument.The method for unlocking of cylinder lock has iron wire hook, chewing gum, cloth, comb, hits the method for unlocking more than ten kinds such as spoon and special-purpose lockaid gun, and this type of is locked very easily by pirate of the open.Along with modern social development, people are more and more higher to the requirement of confidentiality and privacy, and the tapered end of various raising confidentiality arises at the historic moment, and permanent magnetism mechanical type coding lock is wherein a kind of.Permanent magnetism mechanical type coding lock general using permanent magnet same polarity is repelled mutually, the design of heteropolarity phase attraction principle, permanent magnet in the magnetic key in certain sequence, position, polarity arrange, when the magnetic key insertion has the mechanical lock of permanent magnet, as long as the key magnet is corresponding fully with lock magnet positions and polarity, then make permanent magnet displacement in the lock by repulsion, thereby relieving locking bolt, lock is opened, be this type of as Chinese patent literature CN201121443Y, CN201246019Y, the disclosed magnetic lock of CN102003111A.But there is a deadly defect in existing this class magnetic lock, and the quantity of first magnetic bullet, second magnetic bullet and the 3rd magnetic bullet in the magnetic lock is more than two groups, distribution rule, and key is a bare metal rod.The principle that the robber is easy to utilize the magnetic dot homopolarity that is imbedded in key inside to repel is mutually pushed up pellet shot from a slingshot and is limited the position, thereby makes the lock core rotation remove obstacle.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of lock core internal information and structure magnetic lock that be difficult for being detected, that mutual opening rate is extremely low.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of magnetic lock, comprise key, lock core and install and fix the overcoat of this lock core, described lock core comprises outer lock core and the internal cylinder of being made by non-magnet_conductible material, be installed in the described outer lock core to described internal cylinder coupling, and the two is rotatably assorted, described internal cylinder is provided with the keyhole that is complementary with described key, on described lock core, be provided with two pellet shot from a slingshot holes at least, it connects and forms by being arranged on the blind hole on the internal cylinder and being arranged on accommodation hole on the described outer lock core, and each accommodation hole aperture is less than its corresponding blind hole aperture, be disposed with back-moving spring from little cross section end to the big cross section end in described pellet shot from a slingshot hole, can be in this pellet shot from a slingshot hole slide displacement T type post and only can be in blind hole the magnetic posts (diameter that is described magnetic posts is greater than the accommodation hole aperture that constitutes its pellet shot from a slingshot hole, place) of slide displacement, described be respectively arranged with on the key with described each pellet shot from a slingshot hole in the corresponding magnetic patch of magnetic posts, when it correctly places lockset position of coupler, each magnetic patch is the position at corresponding described magnetic posts place respectively, the magnetic pole of the two opposite face is identical, and the T type post that repulsive force between the two is enough to dock with it is pushed in the corresponding accommodation hole fully; During locking, each magnetic posts is reset the spring bullet to the blind hole bottom, and described T type post is in the braking of formation at the interface of internal cylinder and outer lock core.

On described lock core, at least also be provided with an antitheft brake hole, it connects and forms by being arranged on the blind hole on the internal cylinder and being arranged on accommodation hole on the described outer lock core, and each accommodation hole aperture is less than its corresponding blind hole aperture, be disposed with back-moving spring from little cross section end to the big cross section end of described antitheft brake hole, the plunger that in accommodation hole, slides, the ┯ type post and the magnetic bullet of slide displacement in the certain limit in the pellet shot from a slingshot hole, and the butt diameter of described ┯ type post is greater than the accommodation hole aperture of its pellet shot from a slingshot hole, place one end, when described key correctly places lockset position of coupler, the thin end of described ┯ type post just submerges in the blind hole, as not using correct key or method, then easily touch the internal outer lock core of ┯ type post and form braking, prevent by pirate of the open.

Described keyhole is cylindrical, or triangular prism shaped, or is four prism type, or is pentagonal prism shape.

Described each pellet shot from a slingshot hole along lock core shaft to or/and radially be interspersed.

Have at least the magnetic pole distribution arrangement of a magnetic posts opposite in the described magnetic posts with other direction.

Described magnetic posts is made by Nd-Fe-Bo permanent magnet material.

The utlity model has actively useful effect:

The utility model mutual opening rate is low, and lock core internal information and structure are difficult for being detected, and can effectively prevent pirate of the open, and safe and reliable ability promotes applying of magnetic lock.
