Description

Idle AB lock cylinder

Technical field

The present invention relates to a kind of idle AB lock cylinder, belong to field of lockset.

Background technology

Lock is the article that can't leave in people's daily life, human preserves important article with locking since ancient times always, makes the property of oneself can be not stolen by others.Along with the development of science and technology, emerge in an endless stream such as the advanced persons' such as coded lock, electronic lock, Fingerprint Lock lock, but complicated structure and fancy price make these locks can only be applied in some important departments lock the most frequently used or the standard machinery structure in people's daily life.The lock of existing machinery structure comprises lock body and lock core, and described lock core is the cylindrical of interior sky, has key; Described lock body sheath is connected on the lock core outside, and under the lock opening, lock core can rotate with respect to lock body; Be provided with several pellets in the lock body, when key did not insert key, pellet withstood lock core under the effect of spring, and lock core can't be rotated; When correct key inserted keyhole, tartar on the key headed into described pellet in the lock body, and lock core can be rotated with respect to lock body.The lock of this structure, have following problem: 1, Key structure is simple, is easy to copy; 2, billiards structure is simple, makes lock be easy to technical opening, and theftproof is poor.

So in technological progress, people design blade lock, the multiple lockset such as racing lock, blade lock has adopted blade construction, and it is simple to have solved billiards structure, makes lock be easy to technical opening, the problem that theftproof is poor.

Racing lock is the structure that has adopted the lock core idle running, avoids enough in the large unlocking tool, reversing by force lock core at working strength, will lock inner structure and destroy, and the lockset violence is opened.

AB is locked in very sufficient development in the prior art, refer to that lockset has two covers or the above different keys of two covers, so that in the processes such as finishing, the engineering staff holds a key, after finishing is finished after having used house-owner's key, the key inner structure changes, the key that the engineering staff holds no longer can use, and avoids like this house-owner for the problem of safety replacing lockset, and safety is good, it is convenient to use, and obtains at present to use widely.

The blade type AB lock that does not also have idle running in the prior art.

Summary of the invention

Do not inserting key or key when incorrect, the lock core inner structure is in the lock state, vertically driver blade closely cooperates with driver blade up and down, transmission is prominent to be embedded in the bayonet socket, and the front and back lock core brace is withstood, and locks the pellet that resets and is in the direction of pressing to lock body, like this, the front end of front and back lock core brace and the tail end of front lock core are on same line of demarcation, and front lock core separates with rear lock core, reach the purpose of idle running.

When key is in correct status, teeth cooperate correct, and the locking plate groove of locking plate is in correct position, and driver blade is to bottom offset up and down, bottom falls into the locking plate groove on the locking plate, the prominent edge of transmission skids off on the inclined-plane at driver blade bayonet socket edge up and down, under the effect of elastic force, locks the pellet that resets and upsprings, the front and back lock core brace is promoted displacement, its front and back lock core is connected, drive rear lock core, stressed unblanking.

Compared with prior art, the invention has the beneficial effects as follows:

The blade lock that does not also have idle running in the prior art, and the blade lock of prior art also is difficult to the performance of the used for changeable keys of realization AB lock.

The present invention adopts the structure of the idle running of locking plate device, under the external force turning effort, can rotate freely with external force, as, when non-normal use human electric drill bored movable lock core, lock core rotated with the application of force of electric drill, can not bored by electric drill bad, safer.

Transmission device of the present invention adopts two transmissions prominent, when transmission device is struck, displacement is given birth in first transmission burst, but this displacement is so that second prominent combination with bayonet socket of transmission is more tight, unblank can be not successful so that stir, increased safety, but, uprush when adding as 3 when transmission, because the principle of lever, transmission device is unstable on the contrary, uprush when transmission and to add as 4 or 4 when above, the effect of playing and transmission be prominent that to be 2 be sample, structure complicated not only, and owing to will cooperate with transmission is prominent, need up and down to arrange a plurality of bayonet sockets on the driver blade, like this, reduced the up and down intensity of driver blade, the safety of locking has been caused adverse effect on the contrary.

The AB lock of prior art is generally the structure of pellet, as everyone knows, cylinder lock has certain defective at the phase-locked ratio of safety and locking plate, the present invention adopts locking plate to be provided with the structure of two or more grooves, realizes AB lock or many functions that key changes, and the locking plate body is the structure of semicircle or semicircular, two twin-lock chip architectures that locking plate is relative, two locking plates cooperations are moved when stirred by external force, can be simultaneously not stressed, increased greatly safety.

The present invention is scientific and reasonable for structure, and safety is good, is fit to extensive use.
