Description

Safe locking device

(1) technical field

The utility model relates to a kind of lock.

(2) background technology

Lock is important anti-theft device, all reaches antitheft purpose by lock in various doors, so the application of lock is very extensive.Difference lock according to application purpose has the different form of structure of installing and using on padlock, single tongue or two flapper lock, security door and the safety cabinet such as link lock.No matter be the lock of what form, its important component part is exactly a locking device.The locking device of lock all is made up of the pellet shot from a slingshot that cooperatively interacts between lock body, lock core and lock body and the lock core at present.

In order to guarantee safety, people are also constantly carrying out the improvement of lock.But concentrating on mostly, the improvement of being carried out gains in strength and at aspects such as the outer increase of lock protectors.The locking device fundamental form of all kinds lock is changed little together.Its basic functional principle is: have at least one group of pellet shot from a slingshot hole in lock body and the lock core, pellet shot from a slingshot is separately installed with pellet shot from a slingshot in the hole, in the pellet shot from a slingshot hole of lock body spring is installed also, behind the lock locking, lock body is corresponding with the pellet shot from a slingshot hole on the lock core, the end of the pellet shot from a slingshot on the lock body extend in the pellet shot from a slingshot hole on the lock core, has limited the rotation of lock core, reaches antitheft purpose.After the key that will lock was inserted in the keyhole on the lock core, key bit outwards pushed up the pellet shot from a slingshot in the lock core, promotes the pellet shot from a slingshot in the lock body simultaneously, make the contact surface of two pellets shot from a slingshot just in time be in the contact surface place of lock body and lock core, screw key just can drive the lock core rotation, reaches the purpose of unlatching.The safe antitheft performance of this form of structure is not very good, and thief happens occasionally by the case of illegally unblanking to steal.

According to one's analysis, the used means of illegally unblanking of offender are two kinds nothing more than.A kind of be by means of instrument to lock implement to pound, prize, destructive mode such as cutting.Another kind is all to be cylindrical hole according to the pellet shot from a slingshot hole, pellet shot from a slingshot all is cylindric, when pushing up the contact surface place of lock body and lock core, each contact surface to pellet shot from a slingshot has the characteristics of apparent in view sensation, earlier lock core is added a revolving force with instrument, one by one the contact surface of every pair of pellet shot from a slingshot is pushed up the contact surface place that just in time is in lock body and lock core with instruments such as steel wires again, owing in advance lock core is added with turning moment, so not only each contact surface to pellet shot from a slingshot push up lock body and lock core the contact surface place time have an apparent in view sensation, but also can limit moving of pellet shot from a slingshot, make it can not extend into again in the pellet shot from a slingshot hole of lock core, reach rotary locking cylinder at last, the purpose that lock is opened.Preceding a kind of method can produce the bigger sound, and then a kind of method but can be finished in silent, is commonly referred to " technical " and unblanks, and adopts the offender's of a kind of mode in back criminal activity and difficulty to be found.After a kind of method be the trick of illegally unblanking that some offenders use always, and the controlling organization structure of all locks be difficult to be taken precautions against now.

(3) utility model content

The safe locking device that provides a kind of security performance good, simple in structure, easy to install is provided the purpose of this utility model.

The purpose of this utility model is achieved in that it comprises cylinder dress overcoat, in overcoat, be provided with cylindrical chute body and cylinder-shaped marble body, have chute on the cylindrical chute body, slide block and sliding block spring are installed in the chute, have on the inwall of overcoat and the corresponding longitudinal fluting in slide block outer end and the annular groove that each longitudinal fluting is connected, have the pellet shot from a slingshot hole on the pellet shot from a slingshot body, pellet shot from a slingshot and marble spring are installed in the pellet shot from a slingshot hole, it also comprises key, the composition of key comprises key body, and push rod is installed on the key body.

The utility model can also comprise some architectural features like this:

1, have the stairstepping jogger hole on the described key body, have one section ladder platform on the push rod, push rod is installed in the jogger hole, is set with push rod spring on the back segment of push rod, and the rear portion of jogger hole is provided with adjusts the silk nail.

2, on the longitudinal fluting on the outer casing inner wall, have false annular groove.

3, the chute on the described chute body has 4-12, and chute equidistantly distributes along chute body bus, and the quantity of the longitudinal fluting on the outer casing inner wall is equal to or greater than the quantity of chute, but has the longitudinal fluting and the slide block outer end that equate with the quantity of chute corresponding.

4, described slide block is " L " shape.

Major advantage of the present utility model is embodied in:

1, can solve the problem that " technical " unblanks fully.Under locking states, because the length difference of the pellet shot from a slingshot of in the pellet shot from a slingshot body, installing, so the slide block in the slide body is in different height under the effect of sliding block spring, so pellet shot from a slingshot body, slide body all can not rotate in the longitudinal fluting on the outer casing inner wall because the outer end of slide block extend into.After in the pellet shot from a slingshot hole of key being inserted on the pellet shot from a slingshot body, push rod on the key promotes pellet shot from a slingshot and moves, slide block is slided in longitudinal fluting, the outer end of all slide blocks all is in and the corresponding position of annular groove, key just can drive the rotation of pellet shot from a slingshot body and slide body like this, reaches the purpose of unblanking.When the taking-up key and after locking again, slide block can return to original height again under the effect of sliding block spring.The utility model must just can be unblanked when all slide blocks all are in the position of annular groove, can solve the problem that " technical " unblanks comprehensively, has improved the security performance of lock.

2, assembling key voluntarily.Can be equipped with many pellets shot from a slingshot different in size when dispatching from the factory, assemble, adjust key voluntarily, have more safety according to the length of selected each pellet shot from a slingshot; When key loss, just can re-assembly key voluntarily as long as remember the password on the former push rod, exempt the trouble of preparation key.

3, on key body, have the stairstepping jogger hole, have one section ladder platform on the push rod, push rod is installed in the jogger hole, be set with push rod spring on the back segment of push rod, the rear portion of jogger hole is provided with under the condition of adjusting silk nail composition key, and key is not when using, and each push rod stretches out the equal in length of key body end, the shape of all keys is identical when dispatching from the factory, and the phenomenon that can prevent illegally to be disposed standby key after lockset dispatches from the factory takes place.After inserting key in the keyhole, push rod moves under the jacking of slide block earlier, is withdrawn in the jogger hole, promotes slide block slip after jackscrew contacts until push rod with adjusting again, each push rod equates with the length sum that slide block moves like this, can eliminate the feel that " technical " unblanks fully.

4, on the longitudinal fluting on the outer casing inner wall, have false annular groove, can give and illegally carry out " technical " person of unblanking, increase it and carry out the difficulty that " technical " unblanks with fascination.

The utlity model has advantages such as safe and reliable, simple in structure, easy to install in a word.Go for padlock, two flapper locks, safe-guard door lock, automobile, motorcycle, bicycle lock and safety cabinet lock etc.
