Abstract

A burglarproof lock comprising a clutch mechanism comprises a lock-core stator (30), a lock-core rotor (20), especially a clutch pushing unit (80) and a clutch accepting unit (90). When the key is plugged into a keyhole (11) on the lock-core rotor (20) and reaches the designated position, the clutch pushing unit (80) pushes the clutch accepting unit (90) to accept the driving of the lock-core rotor (20) and rotate along with the clutch pushing unit (80), and thus the clutch accepting unit (90) brings about a lock pin (93) on the clutch accepting unit (90) rotating. The existing illegal unlocking technique can not rotate the rotor of the lock core, or the clutch mechanism can not be closed even if the illegal unlocking technique can rotate rotor, so that the existing illegal unlocking technique can not open such kind of lock and safety is guaranteed.

Description

A kind of theftproof lock that clutch is arranged

Technical field

The utility model relates to the lock that tumbler could be located after filling in key, the lock that particularly starts with the key edge or could locate with the tumbler after filling in key that start on other surfaces of key.

Background technology

The door lock of prior art generally is that the dead bolt of lock core assembly inside directly is connected with the mechanism that drives locking bolt, on door, make a call to the total pore-forming of a lock core during installation, the lock core assembly passes from the hole, there are two attachment bolts in door, the lock core assembly to be fixed on the door, the dead bolt of lock core assembly inserts the dead bolt hole of lock body then, when inserting the key of this lock in the lock core assembly, rotor rotation drives dead bolt and rotates, and stretches out or withdraws thereby drive on the lock body locking bolt.The shortcoming of this prior art lock is, as long as rotor rotation must drive dead bolt and rotate, in case the lawless person unblanks rotor rotation by illegal technological means, safety can not get ensureing.

For example the disclosed name of patent No. CN94225450.3 is called the technical scheme of " multifunction anti-theft lock ", what say is that " its structure is that the outside is a lock tube; the centre is a lock body; the inside is the lock core assembly; the left and right sides and top side at the lock core assembly are equipped with reducing pellet shot from a slingshot group respectively; the centre has the round key hole; front end is taper, reducing pellet shot from a slingshot group is staggered the arrangement around the lock core assembly, key is cylindrical, front end is taper, and is corresponding with keyhole, and the key left and right sides and top have and the corresponding breach of reducing pellet shot from a slingshot group ".Though it is simple in structure that this scheme has, to produce easily, three pellets shot from a slingshot are taken precautions against the good advantage of performance, and it does not solve his human unlocking technique rotary rotor, the problem that the safety of lock can't be protected.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art part, the inner band of a kind of lock core assembly clutch is proposed, and the pellet shot from a slingshot of this lock is adopted locking edge strip and locking cylinder with Margin shape pellet shot from a slingshot pearl, bar shaped, existing so illegal unlocking technique not only can't make lock core rotor rotate, even if can rotary rotor, can not make the clutch closure, thus can not open lock, thus guaranteed the safety of locking.

The utility model is realized by adopting following technical scheme:

Manufacture and design a kind of theftproof lock that clutch is arranged, comprise lock core stator, lock core rotor, especially also comprise that clutch pushing unit and clutch accept the unit, described clutch pushing unit is after key inserts from the keyhole of lock core rotor and puts in place, push clutch and accept the unit, make clutch accept the unit in company with the clutch pushing unit together can hard to bear lock core rotor driving and rotate, rotate thereby drive the dead bolt that clutch accepts on the unit.

Described clutch pushing unit comprises at least one catch bar, and the termination of each catch bar is provided with at least one promotion pearl; Described clutch pushing unit also comprises middle projection, and the convexity capital is on the clutch spring; Described clutch pushing unit also comprises clutch block, with the clutch block corresponding position, clutch is accepted the unit clutch slot, does not insert the state of lock core rotor at key, the clutch spring ejects the position of leaving clutch slot to clutch block with the clutch pushing unit, and the termination of described catch bar will promote pearl and eject; At the state that key inserts lock core rotor and puts in place, the key compressing promotes pearl, and the termination that promotes pearl compressing catch bar makes the clutch pushing unit accept the unit to clutch to close up, thereby makes clutch block fall into clutch slot.

Described key compressing promotes pearl, is that the extruding of key side promotes pearl.

Or described key compressing promotion pearl, be that following on the key extruding promotes pearl.

Described following on the key compressing promotes pearl, is that following on the key extruding earlier drives pellet shot from a slingshot, promotes pearl by driving the pellet shot from a slingshot extruding again.

The utility model also has following scheme implementation:

Design a kind of theftproof lock that clutch is arranged, comprise lock core stator, lock core rotor, especially the pellet shot from a slingshot in the lock core rotor is that the centre of bar shaped has the protruding Margin shape pellet shot from a slingshot pearl that goes out of dome-shaped; the protrusion position of the Margin shape pellet shot from a slingshot pearl of stating, correspondence is provided with the locking edge strip, at the opposite side of locking edge strip, correspondence is provided with the locking cylinder, and described locking cylinder is in the half slot in the lock core stator and locks between the edge strip

Two terminations of Suo Shu Margin shape pellet shot from a slingshot pearl, a spoon hole corresponding to key, another contacts with marble spring.

Described have more than one spoon ditch on the key, and described spoon hole is provided with in the spoon ditch.

The keyhole that is complementary with key is arranged on the described lock core rotor, be provided with in the inner end of keyhole and promote pearl.

The front end of described key has protuberance, and this protuberance protrudes forward along the center of key, promotes pearl in order to back down.

Compared with prior art, the pellet shot from a slingshot of the utility model lock is adopted with the locking edge strip of Margin shape pellet shot from a slingshot pearl, bar shaped and locking cylinder, existing so illegal unlocking technique not only can't make lock core rotor rotate, even if can rotary rotor, because the utility model has clutch, its illegal unlocking technique can not make the clutch closure, thus can not open lock, thus guaranteed the safety of locking.
