Abstract
The invention relates to a magnetic combination pin tumbler lock and a magnetic coding key, which comprises a lock body, a plug and a key; A pin tumbler hole on the plug runs radially from the external surface until the vicinity of a keyhole but is not communicated with the keyhole, the lock body is provided with a pin tumbler hole which is corresponding to and communicated with the pin tumbler hole on the plug, a fixed nonferrous magnetic plug is arranged at the end face of the pin tumbler hole of the lock body and the end face is near to the outer diameter, a permanent magnetic pin tumbler is arranged in the pin tumbler hole. The key and the pin tumbler of the invention are contactless with each other; furthermore, the position of the pin tumbler is concealed and is hard to be detected; additionally, the pin tumbler holes are designed to be distributed with equal or unequal spacing or in a spiral way along the axial direction of the plug, which can produce complex key codes that are difficult to be repeated; the magnetic polarity of a permanent magnetic bar embedded in the key is arranged in an inconsistent way, so the invention has strong resistance to the key duplication. The invention is simple in structure, low in manufacturing cost, easy in maintenance and convenient and reliable in use; when the key hole is inserted by the foreign matter, the foreign matter is easy to be removed, so the invention has strong damage resistance.
Description
Technical field
The present invention relates to a kind of magnetic cylinder lock, relate in particular to a kind of magnetism hybrid spring lock and magnetism coding key.
Background technology
The magnetic cylinder lock of magnetic bullet is housed at present, traditional master key is had good strick precaution ability, but generally use ferromagnetic key to insert in the keyhole, the permanent magnetism pellet shot from a slingshot is adsorbed onto makes lock core and lock body unlocking function on the key.Its defective is that pellet shot from a slingshot hole and keyhole run through, thereby easy position of from keyhole, seeing or finding out the pellet shot from a slingshot hole, and the permanent magnetism pellet shot from a slingshot of putting is regardless of polar orientation, can use and have ferromagnetic metal bar pirate of the open, and the easy blocked foreign matter of keyhole and being damaged, or cause to open under the permanent magnetism pellet shot from a slingshot can't being inhaled because of the magnetic conductivity of key is bad and do not lock.
Summary of the invention
For overcoming the defective of present magnetic cylinder lock, the invention provides a kind of cylinder lock that prevents pirate of the open or destruction.
The present invention is achieved in that a kind of magnetism hybrid spring lock and magnetism coding key, comprises lock body, lock core and key, described lock core be provided with the pellet shot from a slingshot hole and with the corresponding keyhole of key, lock body be provided with lock core on the pellet shot from a slingshot hole of the corresponding perforation in pellet shot from a slingshot hole; Described pellet shot from a slingshot hole is provided with more than 2 or 2 along the lock core axial distribution, and the pellet shot from a slingshot hole is radially worn to nearly keyhole by external surface along lock core and ended and do not connect with keyhole; The end face in outer footpath is provided with fixing non-ferromagnetic stopper on the pellet shot from a slingshot hole of lock body, is equipped with the permanent magnetism pellet shot from a slingshot in the pellet shot from a slingshot hole, and includes first scheme or alternative plan, or the combination of first scheme and alternative plan; Described first scheme: below the permanent magnetism pellet shot from a slingshot, be equipped with spring, and the permanent magnetism pellet shot from a slingshot is between the bonding surface of lock core and lock body form locking states, when key inserts keyhole when putting state in place, it corresponds to place, pellet shot from a slingshot hole site and is embedded with Permanentmagnet bar, and the magnetic polarity of Permanentmagnet bar is opposite with the polarity of the corresponding end of permanent magnetism pellet shot from a slingshot, and the permanent magnetism pellet shot from a slingshot is sucked in the pellet shot from a slingshot hole of lock core form released state; Alternative plan: above the permanent magnetism pellet shot from a slingshot, be equipped with non-ferromagnetic pellet shot from a slingshot and spring successively, and non-ferromagnetic pellet shot from a slingshot is between the bonding surface of lock core and lock body form locking states, when key inserts keyhole when putting state in place, it corresponds to place, pellet shot from a slingshot hole site and is embedded with Permanentmagnet bar, and the magnetic polarity of Permanentmagnet bar is identical with the polarity of the corresponding end of permanent magnetism pellet shot from a slingshot, and can repel each other with the permanent magnetism pellet shot from a slingshot and non-ferromagnetic pellet shot from a slingshot is headed in the pellet shot from a slingshot hole of lock body and form released state.
The magnetic polarity of described embedded Permanentmagnet bar is on the key arranged has at least 1 polarity with other Permanentmagnet bar opposite.
Described pellet shot from a slingshot hole is equally spaced to being equidistantly or not along lock core shaft, or along lock core shaft to being equidistant or unequal distant screw distributes.
As a further improvement on the present invention, described lock core is provided with the keyhole of tubular, and the portion's relative set that rises of described key becomes cylindricality; Described keyhole is cylindrical shape or square tube shape or terraced tubular or inequilateral triangle tubular.
The hole wall of keyhole is provided with a protruding grain, and the portion of rising of key is provided with and the corresponding spill guide groove of protruding grain.
Further improve as of the present invention, the hole wall of keyhole is provided with a spill guide groove, and the portion of rising of key is provided with and corresponding fin of spill guide groove or protruding grain.
Realize the present invention, because the pellet shot from a slingshot hole do not connect with keyhole, keyhole is arranged to the tubular that is smooth, make key become contactless state with pellet shot from a slingshot, and the position of pellet shot from a slingshot obtains hidden and difficult being found out; Again because the pellet shot from a slingshot hole be arranged to along lock core shaft to being equidistantly or not being equally spaced or becoming spiral distribution, can generate the key code of complicated difficult repetition, and the magnetic polarity of embedded Permanentmagnet bar becomes inconsistent arrangement on the key, thereby has the stronger imitative bitting ability that prevents.Of the present invention simple for structure, cost of production is lower, and maintenance easily, and is easy to use and reliable; When being easier to get rid of by filling foreign matter time ratio in the keyhole, anti-destructive is strong.
