Abstract

The utility model discloses a technical unlocking preventing lock. One of lock cylinder full-stroke marble holes with the unified length in an existing spring lock cylinder is changed into a lock cylinder half-stroke marble hole, a lower marble in the hole is a short lower marble, the front lower marble adjacent to the short lower marble is a long lower marble, and an upper marble corresponding to the lock cylinder half-stroke marble hole is an upper marble with the slightly small diameter. Due to the fact that the gap of the upper marble with the slightly small diameter is obviously larger than the gaps of other upper marbles, a master key must be located at the upper marble with the slightly small diameter when being used for conducting unlocking, then other lower marbles are clamped since the vertical distance between the short lower marble and the bottom of the front long lower marble adjacent to the short lower marble is larger than the size of a protrusion of a hook of the master key, the master key cannot eject the short lower marble, and then the technical unlocking preventing lock cannot be unlocked. When the short lower marble located in the lock cylinder half-stroke marble hole falls to the lowest position, there is a certain distance between the bottom face of the short lower marble and the highest position where a vibration lock remover vibrating piece is located when vibrating, a vibration lock remover has on effect on the short lower marble, and then the lock cannot be unlocked.

Description

Anti-technology unlocking cylinder lock

Technical field

The utility model relates to a kind of cylinder lock, and especially one can prevent that experienced robber from utilizing master key or utilizing vibration lockaid gun to unblank, and is the splendid anti-technology unlocking cylinder lock of antitheft energy.

Background technology

At present, in known cylinder lock, upper pellet in lock body in every row marble hole is identical, but because foozle causes pellet and lock spring interporal lacuna to have trace different, experienced robber's method for unlocking is: first will pull out hook and insert lock core neutral place to a torque of lock core generation, then touch lower pellet with master key top, first a pair of upper and lower pellet of gap minimum is pushed up to lock core and lock body intersection, now, lock core turns over an angle pulling out trace under hook torque, then one by one in pairs upper and lower pellet is pushed up to lock core and lock body intersection from childhood and greatly by pellet gap, now lock core is being dialled under hook torque, trace increase turns over an angle one by one again.Until last pushes up lock core and lock body intersection to upper and lower pellet, now lock core is pulling out under hook torque and can significantly rotate, and lock has also just been opened, therefore be absolutely unsafe.

Meanwhile, in known cylinder lock, when each lower pellet is fallen extreme lower position, its bottom surface all can arrive computerized version keyhole inner bottom surface or S type keyhole internal projection part in lock core.The method of utilizing vibration lockaid gun to unblank is: the each tartar groove of vibration lockaid gun vibrating reed is all set by the longest lower pellet, the vibration lockaid gun vibrating reed that inserts lock core can produce micro breadth oscillation top and touch lower pellet, one by one in pairs upper and lower pellet is shaken to lock core and lock body intersection from childhood and greatly by pellet gap, now lock core is under the torque of vibration lockaid gun vibrating reed, and trace increase turns over an angle one by one.Until last shakes to lock core and lock body intersection to upper and lower pellet, now lock core can significantly rotate under vibrator vibrating reed torque unblanking, and lock has also just been opened, therefore be absolutely unsafe.

Summary of the invention

The deficiency that can open with master key or vibration lockaid gun in order to overcome existing cylinder lock.The utility model provides a kind of anti-technology unlocking cylinder lock, and it can thoroughly stop with master key or the unlatching of vibration lockaid gun, thereby greatly improves safety.

The technical scheme that the utility model technical solution problem adopts is: make one of them of the omnidistance marble hole of lock core of unified length in lock core in existing cylinder lock into lock core half way marble hole, lower pellet in lock core half way marble hole is selected pellet under short type, under this short type, before pellet, an adjacent lower pellet is selected pellet under elongated, meanwhile, the upper pellet on one of them corresponding lock core half way marble hole of pellet in the standard of unified diameter in existing lock marble hole is selected to the smaller upper pellet of diameter.

Be positioned under the short type of lock core half way marble hole when pellet is fallen extreme lower position, its bottom surface during still apart from the vibration of vibration lockaid gun vibrating reed highest order be equipped with a segment distance, so cannot be in contact with it when the vibration of vibration lockaid gun vibrating reed, just cannot drive its up-down vibration, so pellet rests on original position all the time under this short type, the smaller upper pellet of lock marble hole interior diameter matching therewith still blocks lock core under spring force effect, and this lock cannot be opened with vibration lockaid gun.

Simultaneously, the gap of the smaller upper pellet of diameter and lock marble hole is obviously greater than the gap of pellet and lock marble hole in other each standard, must be right in last in the time that master key is unblanked, when other each lower pellet has all been pushed up to lock core and lock body intersection by master key, now lock core turns over an angle pulling out trace under hook torque, cause other each lower pellet all to be removed (comprising pellet under elongated) by card, because the upper and lower gap in bottom that is positioned at bullet under pellet under the short type in lock core half way hole and an adjacent elongated is above greater than the size of master key hook projection, master key now cannot push pellet under this short type, because finally under this short type, pellet still rests on original position, the smaller upper pellet of lock marble hole interior diameter matching therewith still blocks lock core under spring force effect, this lock cannot be opened with master key.

The beneficial effects of the utility model are: this lock after thoroughly having stopped to utilize master key or vibration lockaid gun to open, theftproof performance is good, and simple and reliable for structure.

Smaller upper pellet 7. springs of pellet 6. diameter in pellet 5. standards under the short type of pellet 4. under the omnidistance marble hole 2b. of 1. lock body 2. lock core 2a. lock cores lock core half way marble hole 3. elongateds in figure

In the embodiment shown in fig. 1, make one of them of the omnidistance marble hole 2a of the lock core of lock core 2 interior unified length in existing cylinder lock into lock core half way marble hole 2b, lower pellet in lock core half way marble hole 2b is selected pellet 4 under short type, under this short type, before pellet 4, an adjacent lower pellet is selected pellet 3 under elongated, meanwhile, the upper pellet of one of them corresponding lock core half way marble hole 2b of pellet 5 in the standard of unified diameter in existing lock marble hole is selected to the smaller upper pellet 6 of diameter.

Be positioned under the short type of lock core half way marble hole 2b when pellet 4 is fallen extreme lower position, when its bottom surface still vibrates apart from vibration lockaid gun vibrating reed, highest order is equipped with a segment distance, so cannot be in contact with it when the vibration of vibration lockaid gun vibrating reed, just cannot drive its up-down vibration, therefore under this short type, pellet 4 rests on original position all the time, the smaller upper pellet 6 of lock marble hole interior diameter matching therewith still blocks lock core 2 under spring 7 elastic force effects, and this lock cannot be opened with vibration lockaid gun.
