Description
Affiliated technical field
The utility model relates to a kind of lock core, relates to a kind of technical unlocking that prevents specifically, and can prevent the nothing point Anti-drilling lockwork unblank with boring.
Background technology
The use of lock and extensive be unable to do without lock in daily life, lock is a kind of protection tool, in order to protection property and life security.According to the different purposes of lock, the mechanical strength of lock and firm performance have very big difference, but with regard to the purpose of lock, any lock all needs stronger anti-open function.Present lockset, mostly be that lock core and tapered end are formed, during use, lock core is stuck and can not rotates, so do not have key operatedly just can't open lock, but these locks, because lock core is fixed, origin of force is obviously outstanding, so the thief can use brill to wait instrument, utilize this lock that the characteristic of origin of force is arranged, open lockset very easily; And this some snap that is locked in is to after good, promptly can cause control to tilt, make each snap origin of force feel more obvious, the chance that can cause technical unlocking for unlocking tool persons such as using master key is so the performance of anti-technical unlocking of these locks and anti-drilling unlatching is relative relatively poor.In order to prevent to unblank with boring, some is locked on the material and improves to some extent on the market, but this also makes the cost of lock increase, and can not reach the anti-drilling effect of technology, does not tackle the problem at its root.
Summary of the invention
In order to overcome the shortcoming of anti-technical unlocking of existing lockset and anti-drilling unlatching poor-performing, the purpose of this utility model is to provide a kind of nothing point Anti-drilling lockwork, and this lock core structure is simple, with low cost, use easy and simple to handlely, the safe antitheft performance is strong, anti-technical unlocking and anti-drilling effective.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of nothing point Anti-drilling lockwork, comprise lock core and lock core cover, said lock core comprises internal cylinder and outer lock core, in the said lock core cover outer lock core is installed, internal cylinder is installed in this outer lock core, said internal cylinder is provided with keyhole, on the said outer lock core dead bolt is installed, its structural feature is: said lock core is provided with a plurality of pellets shot from a slingshot hole, pellet shot from a slingshot and marble spring are installed in the pellet shot from a slingshot hole, all have the pellet shot from a slingshot chute on each pellet shot from a slingshot, said internal cylinder is axially installed slide plate, and the position of corresponding each pellet shot from a slingshot has the pellet shot from a slingshot slide opening on this slide plate, has skateboards slot on the said slide plate, one end of slide plate is installed skateboard spring, have the elastic rod hole at lock core and lock core cover with the skateboards slot corresponding position, elastic rod and elastic rod spring are installed in this elastic rod hole, said elastic rod comprises the internal cylinder elastic rod, outer lock core elastic rod and lock core cover elastic rod, the height of internal cylinder elastic rod is: when the internal cylinder elastic rod did not enter in the skateboards slot, the top of internal cylinder elastic rod and internal cylinder cylindrical were flat; The height of outer lock core elastic rod is: outer lock core wall thickness and skateboards slot groove depth and.During use, the key bit and the pellet shot from a slingshot of this lockset are complementary, so, when not opening with this lock key, when the internal cylinder elastic rod does not enter in the skateboards slot, the top of internal cylinder elastic rod and internal cylinder cylindrical are flat, internal cylinder can be rotated relative to outer lock core like this, so on internal cylinder, there is not origin of force, thereby prevent from bore to open and with other aid technical unlockings, and this moment since the height of outer lock core elastic rod be outer lock core wall thickness and skateboards slot groove depth with, so the outer lock core elastic rod is fixed outer lock core and lock core cover can not relatively rotate.When with this lockset key unlocking, because the tooth and the pellet shot from a slingshot of key are complementary, so, after inserting key, pellet shot from a slingshot chute on the pellet shot from a slingshot is in same position, thereby makes slide plate move certain position, at this moment, the corresponding elastic rod of the skateboards slot of slide plate position, the internal cylinder elastic rod is entered in the skateboards slot, and the outer lock core elastic rod also moves inward, and by the outer lock core elastic rod internal cylinder and outer lock core is fixed and can not be relatively rotated, and this moment, the top of outer lock core elastic rod and outer lock core cylindrical are flat, so outer lock core and lock core cover can relatively rotate, at this moment can drive outer lock core with the key turns internal cylinder and rotate, dead bolt on the outer lock core also rotates, and can open lockset.
Said skateboards slot is upper and lower two, and elastic rod and elastic rod spring are all installed in the upper and lower elastic rod hole that has of the position corresponding with skateboards slot in this elastic rod hole.
Said lock core puts and is provided with dowel hole, installing and locating pin and retainer spring in this dowel hole.
Said outer lock core is provided with through hole, mounting spring in this through hole, and bearing pin is installed at the two ends of this spring respectively.
At the anti-drilling backplate of said lock core outer end installation by anti-drilling material.
The beneficial effects of the utility model are, structure of the present utility model adopts internal cylinder, outer lock core and lock core cover, lockset is when lock-out state, fixing can not the rotation between outer lock core and the lock core cover, and can rotate mutually between internal cylinder and the outer lock core, so just making does not have origin of force when originally being locked in lock-out state, because of internal cylinder can be rotated with respect to outer lock core, so can't unblank, and can't unblank, reach the purpose that effectively prevents technical unlocking fully with other unlocking tools with brill.The utility model is simple in structure, and is with low cost, and it is convenient to open, easy operating, and the safe antitheft performance is strong.
