On the inner side of the outer lock core install a separate-and-reunion pattern concave grooves, this grooves can plug in the plug late, on the plug plate install transporting rod, the out side end of transporting rod stretch out from clock cover, on the transporting rod install spring.
Description
Affiliated technical field
The present invention relates to a kind of lock, relate to a kind of clutch type anti-theft lock specifically.
Background technology
The lockset that uses adopts lock core fixed conveyor bar to rotate the conventional art that drives dead bolt mostly now, and is simple in structure easy-to-use, but theftproof performance is relatively poor.Along with the raising of people's security precautions, the theftproof performance of lockset more and more is much accounted of, and its product is also being updated: on tapered end, and the employing cross lock that has, the dull and stereotyped lock of the employing that has, what also have sets up metal cap, anti-drilling sheet etc. in the tapered end outer end; Aspect lock core, its technical measures focus mostly on and are improving key, adopt multiple tooth key of many ribs and equipped mutually pellet shot from a slingshot aspect, in the hope of reducing the mutual opening rate of key.But this lock uses master key or other aids concerning the experience person that necessarily unblanks is arranged, and lock core rotates through dialling to press, by feel or sound, still can more easily open, fundamentally do not solve the problem of pressing pellet shot from a slingshot to unblank of dialling, therefore, the theftproof performance of these cylinder locks is relatively poor.
Summary of the invention
In order to improve existing cylinder lock theftproof performance, the invention provides a kind of clutch type anti-theft lock, this anti-theft lock structure is simple, and is with low cost, easy to install, and theftproof performance is strong, can be effectively anti-drilling, pick-proof, anti-collision, prevent technical opening.
The technical solution adopted in the present invention is:
A kind of clutch type anti-theft lock, comprise lock housing and be installed in the interior lock core of lock housing, its structural feature is: said lock core comprises internal cylinder, this internal cylinder outside suit outer lock core, the inner face of this outer lock core is provided with the clutch groove, and the clutch plate of can pegging graft in this clutch groove is installed drive link on this clutch plate, lock housing is stretched out in the outer end of this drive link, mounting spring on the drive link in lock housing.During use, the pressure of spring enters in the clutch groove clutch plate, this moment, drive link and lock core socket joint were connected as one with key turns, the control dead bolt is opened lock or locking, push inward with key afterwards, internal cylinder promotes the clutch plate and breaks away from the clutch groove, makes drive link and lock core be in disengaged position, thereby uncontrollable dead bolt.
Said outer lock core is provided with L type chute, and the sliding pin that can slide in L type chute is installed on the said internal cylinder.Internal cylinder both can be endwisely slipped in outer lock core, again can be at the outer lock core internal diameter to rotation.During use, by key turns the sliding pin of internal cylinder is entered in the axial groove of outer lock core L type chute, the pressure of spring enters in the clutch groove clutch plate, the back one is with key turns so drive link and outer lock core are pegged graft, so just lock can be opened or locking, push inward with key afterwards, the sliding pin of internal cylinder is entered in the radial slot of outer lock core L type chute, and internal cylinder promotes the clutch plate and breaks away from the clutch groove, can't drive drive link when internal cylinder is rotated and rotate, thereby can't open and close lockset.This moment, lock core can infinitely rotate, and reached anti-drilling, prevented that skill is opened, the purpose of anti-collision.
Said lock housing is provided with pin-and-hole, installing and locating bearing pin in this pin-and-hole, and said outer lock core is provided with locating slot, and alignment pin assigns in the locating slot.By the effect of alignment pin and locating slot, can prevent that lock core from moving axially, do not influence lock core simultaneously again and in lock housing, radially rotate.
Said clutch groove can be the cross slotted eye, and the clutch plate corresponding with the clutch groove can be the cross plate.
Be with fixedly dial on the said lock housing, the rotational password dish is installed on the lock core, the dials of three bands of the outer slip suit of said drive link shifting block, drive link can slide therein.
The invention has the beneficial effects as follows, in order to overcome existing lockset by master key and rigid processing pirate of the open, the present invention adopts the compound control structure of dual lock core, have only the key of this lockset just can make lock core interlock drive link, non-lockset key can only make the invalid rotation under disengaged position of lock core and drive link; The present invention can not find master key and dials pressure sensitivity feel unlatching fulcrum, can effectively prevent technology unlocking instruments such as master key, because lock core of the present invention has unlimited rotatory, so anti-drilling function admirable when lock core caves in through gravity impact, still is separated with drive link.The present invention is simple in structure, uses simple installation, and compliance is strong, can be effectively anti-drilling, pick-proof, anti-collision, prevent technical opening.
