Abstract

The invention discloses an anti-theft lock core and a key matched with the anti-theft lock core, wherein a key jack channel (8) on a rotating lock core (2) is in the shape of an I-shaped spiral cavity, an inclined plane (9) type marble hole (3) correspondingly communicated with a lock core sleeve is arranged below the top end in the cavity and is arranged in the same direction as the spiral cavity, a section of key guide groove sheet (12) is arranged on the side wall above the marble hole (3), when a spiral key is inserted into the key channel (8) during rotation, a key guide groove above the inclined plane at the top end of the key is matched with the guide groove sheet (12), a plurality of circular grooves with different depths on the narrow plane of the key inclined plane are opposite to the circular convex top ends of marbles filled into the marble hole (3), at the moment, the lock core sleeve and the rotating lock core (2) are in a non-clamping state. The lock core adopting the structure can effectively prevent technical opening of various special tools, has the advantages of reasonable structure, simple manufacture and low cost, and can be widely applied to various locks.

Description

A kind of anti-theft lock

Technical field

The present invention relates to a kind of anti-theft lock in mechanical lock field.By lock core sleeve, one can corresponding rotation in lock core sleeve lock core, rotational lock core is provided with the pellet shot from a slingshot hole with the corresponding perforation of lock core sleeve, pellet shot from a slingshot group and one is housed in the pellet shot from a slingshot hole forms with the corresponding key of key hole passage on the rotational lock core.

Background technology

In the present technology of lockset, its pick-proof, protective equipment anti-drilling, protecting against shock are very perfect.The problem but this is nothing concerning those grasp the people that very high-tech is unblanked, they open lock with various special unlocking tools with for many years the experience of unblanking and perceptibility free from worldly cares.No matter which kind of complex structure, the lock that how high precision is, as long as the place that instrument can touch, as long as instrument is not lost can both opening lock of sensing ability, this only time and skilled process problem certainly.

According to the Chinese patent literature that retrieves, publication number is 1710229, the day for announcing is on December 21st, 2005, notification number is 0000000, a kind of lock core is disclosed, its key is the chain link soft, tooth-sheet bent-curved core lock group, it comprises curve lock core and the chain link soft key that matches with it, constitute the curve-like key lock road of advancing, the lock duct device is a three layer construction, be respectively the lock core guide channel plate from the bottom to top, key prerotation vane and pellet shot from a slingshot support anti-rotor, and chain link soft key is by a plurality of narrower books, and thick sheet chain link piece via pins is worn pin and linked, chain link piece one side direction is protruded outward, opposite side is inwardly recessed, all offers pin hole on it, and chain link piece both sides offer the groove that matches with guide channel plate, the keyhole at the cross section of key loop bar and pilfer band middle part all is Pear-Shaped, is provided with anti-drop device between the two.Effectively prevent to twist off or break because of careless manipulation the phenomenon of key, the lock core of this structure has effectively limited the use energy degree of vertical type instrument.But the making of this lock core complexity very, key is again the chain link soft, and manufacturing materials has very high requirement, adds the soft key of chain link formula when the insertion key is advanced the lock road, because lock is crooked in the road, promptly uses also as easy as rolling off a log being fractureed of key of good material.

Summary of the invention

The technical problem to be solved in the present invention provide a kind of theftproof performance more reliable, make a kind of anti-theft lock simple and easy, easy operating.

In order to solve above-mentioned technical problem, the invention provides a kind of a kind of anti-theft lock of this following structure.

This anti-theft lock is by lock core sleeve, one can corresponding rotation in lock core sleeve lock core, on rotational lock core with the pellet shot from a slingshot hole of the corresponding perforation of lock core sleeve, pellet shot from a slingshot is equipped with pellet shot from a slingshot in the hole, the key of key hole passage corresponding configuration is formed on marble spring and one and the rotational lock core, the key hole passage of described rotational lock core is the spiral cavity shape of I font, described pellet shot from a slingshot hole is several, be located at the below, inboard top of the spiral cavity key hole of I font passage, be ramp type, forward arrange with spiraled cavity, on sidewall above the pellet shot from a slingshot hole, be provided with the key guide channel plate of one section convex.

I font spiraled cavity is suitable on described key and the rotational lock core revolves the long body of shape for I font Luo.The inclined-plane that is provided with for the pellet shot from a slingshot hole in the key hole passage on inclined-plane and the rotational lock core below the key top matches, and is provided with several deep mixed circular grooves on the narrow plane on inclined-plane, key top.Also can adopt zigzag convex tooth as required.Above the key inclined-plane, be provided with one section with rotational lock core in the key guide channel plate on the sidewall matches above the pellet shot from a slingshot hole key guiding ditch.

Anti-theft lock of the present invention is compared with the lock core of prior art has following characteristics: owing to be spirality in the key hole passage, prevented the use energy degree of various special unlocking tools effectively, the pellet shot from a slingshot hole is again oblique standard, therefore theftproof performance is more reliable, and it is simple in structure, making is simple and easy, cost of production is low and easy to operate.
