Description

The key of coaxial twin-core theftproof lock and unlatching

Technical field

The utility model relates to theftproof lock and opens the key of theftproof lock.

Background technology

Mechanical lock is a kind of life appliance commonly used.The kind of mechanical lock is very extensive, but the quality of theftproof performance is important quality index of mechanical lock.The mechanical lock of traditional structure cooperates with the interior pellet shot from a slingshot of lock core through key, and lock core and lock tube can be relatively rotated, and drives the tongue switching trip by lock core again and realizes unblanking and locking.But the lockset anti-theft feature of said structure is poor, as long as apply certain button square to lock core, depresses pellet shot from a slingshot with special instrument again, can realize unblanking.Be to solve the problem of mechanical lock anti-theft feature difference, people have done a large amount of research, and Chinese patent number is that the patent documentation of CN2005201132358 discloses a kind of coaxial multicore theftproof lock; It is that lock core is divided into multistage; Make improperly when unblanking to apply the button square,, the button square can not inwardly be transmitted because the multistage lock core does not link to each other to lock core; Simultaneously on the multistage lock core, be provided with self-locking mechanism, thereby realize the purpose of antitheft.Publication number is the disclosed L shaped keyhole pellet shot from a slingshot machinery lock of the Chinese patent document of CN1080351A; It is to utilize lockhole inner space little cooperation tip pellet shot from a slingshot not stay move place for the lock core inner chamber; Making master key or special instrument be difficult to get into lock core can't work, thereby reaches the purpose of antitheft.Above-mentioned various lock anti-theft feature still remains further to be proposed high.

The utility model content

The purpose of the utility model just provides the good theftproof lock of a kind of theftproof performance and opens the key of this theftproof lock.

The technical scheme that the utility model theftproof lock adopts is: coaxial twin-core theftproof lock; It comprises lock tube and lock core, and lock tube is provided with through hole, and lock core is positioned at the through hole of lock tube; It is characterized in that described lock core is divided into two sections; Be respectively preceding lock core, with preceding lock pin coaxial rear lock core arranged side by side, the central authorities of preceding lock core and rear lock core are provided with the lockhole that supplies the key turnover, are respectively equipped with the some groups of pellets shot from a slingshot that cooperate unlatching with key on described lock tube and preceding lock core and the rear lock core; The coaxial cylinder that is provided with in rear portion of lock core before described, the center of cylinder is a lockhole, offers horizontal concrete chute on the cylinder, vertically is connected with minor axis on the cylinder; The corresponding end of described rear lock core and preceding lock core is provided with and the adaptive hole of preceding lock core cylinder, and the wall of rear lock core hole is provided with groove, and the rear lock core through-hole wall of groove one side is provided with one group of thick pellet shot from a slingshot; The cylinder of preceding lock core is positioned at the hole of rear lock core, and makes minor axis be positioned at groove, and thick pellet shot from a slingshot is squeezed in the chute; When lock core rotated before making, chute pushed thick pellet shot from a slingshot and rises, and opens thick pellet shot from a slingshot; Minor axis arrives the end drive rear lock core rotation of groove simultaneously, realizes unblanking.

For increasing theftproof performance, the diameter of said thick pellet shot from a slingshot is greater than the diameter of preceding lock core and rear lock core pellet shot from a slingshot.

A kind of key of opening above-mentioned coaxial twin-core theftproof lock, it comprises spoon plate and handle, and the rear end of spoon plate is provided with rotating shaft, and handle is provided with the through hole adaptive with rotating shaft, and rotating shaft is positioned at through hole connects spoon plate and handle activity; The front end of said handle is parallel with the spoon plate be fixed with preceding lock core lockhole adaptive stretch out plate, on the described spoon plate corresponding before lock core rising makes lock core make hole in relative rotation with lock tube with rear lock core pellet shot from a slingshot position extruding pellet shot from a slingshot; Be provided with between spoon plate and the handle and decide device, make spoon plate plate face hole center line and handle plane be located along the same line.

Adopt technique scheme, make spoon plate get into a lockhole when unblanking, the lockhole of lock core before the stretching out plate and also get into of handle; Pellet shot from a slingshot on preceding lock core and the rear lock core will be opened successively, and turning handle stretches out the moving preceding lock core of strip and rotates; Chute pushes thick pellet shot from a slingshot; Thick pellet shot from a slingshot is opened, and driven the rear lock core rotation, thereby reach the unlatching of whole lock core.Extract key, turning handle when making that through positioner spoon plate plate face hole center line and handle plane are located along the same line, can be extracted key.

Above-mentioned positioner can be provided with like this; It is included in several installing holes that are connected with the through hole of horizontal direction that the handle vertical direction is provided with; Be provided with the spring of compression leg and extruding compression leg in the installing hole; The installing hole correspondence position that is positioned in the rotating shaft of through hole is provided with pothole, makes that spoon plate plate face hole center line and handle plane were located along the same line when compression leg squeezed in the pothole.

Above-mentioned positioner also can be provided with like this, and it comprises pulling block, and described handle is provided with square hole; The through hole of handle passes square hole; The roller end of spoon plate rear end is provided with and rotating shaft bar shaped direction one square groove of making peace, and described pulling block middle part be and the big or small adaptive cylinder of square hole that one end of cylinder is provided with circular shaft; The other end is provided with the square sheet of two symmetric arrangement; The through hole that the circular shaft of pulling block and square sheet are positioned at handle makes pulling block to rotate at square hole, and the size of square sheet and square groove size is consistent, and spoon plate plate face hole center line and handle plane are located along the same line when making two side's sheets entering square groove.

The beneficial effect of the utility model is: the process complicacy because the utility model is unblanked, and the function of existing standard machinery cylinder lock set also increases thick pellet shot from a slingshot simultaneously; Therefore the unlatching of whole lock core is that spoon plate insertion rear lock core rotates to same direction behind the key simultaneously by before the key spoon of moving preceding lock core of strip; Could accomplish unlatching, so anti-theft feature strengthens greatly, the lock core of the utility model be divided into disjunct before lock core and rear lock core; Therefore during skilled unlocking; Add torque for preceding lock core, when current lock core turns an angle and open stealthy thick pellet shot from a slingshot, lock core has blocked the lockhole of rear lock core before making; Can't make the pellet shot from a slingshot playback of rear lock core, therefore take precautions against skilled unlocking effectively.The Key structure of the utility model is complicated, is difficult to duplicate, and has also strengthened anti-theft feature greatly.
