Description

Chain lock

Technical field

The invention belongs to lock technology field, be specifically related to chain lock.

Background technology

Modern is busy with the cause of hurrying back and forth outside, time of having a rest of being in is very short, because science and technology is flourishing now, local and overseas have greatly lockmaking to unblank expert, develop various lockset and unlocking tool, some illegal businessman utilize these high-tech unlocking tools to sell to unblank workman and some do not know the people of its object, earn a large amount of ill-gotten gains, so just there is others' lawless person of object such as to disturb public order unfavorable to some and manufactured convenience, to such an extent as to allow in other people and society and cause a large amount of loss, various countries' locking industry in view of this type of reason manufactures one after another various high-tech theftproof lock to supply market, but how long have more than is needed just have the various unlocking tools for this type of lockset to create, make people hard to guard against, need the chain lock that a kind of anti-theft feature is stronger.

Modern lock main body is divided into mechanical lock and electronic lock two class, and the structure main body of mechanical chain lock is divided into key, lock core, lock body to form.The internal construction of lock core has pellet length or the steel card breach depth, magnet rod anode and cathode cooperation etc., come to coordinate with key to cause pellet parallel divisional in lock core, thus turn key and open lock, these locksets are all utilize outstanding pellet length to coordinate with the concavo-convex depth of key except magnetic core lock, also have the quantity of pellet also very crucial with arrangement, it is better that more with number of the arrangement of pellet maintain secrecy more.Unlocking technique has following several: (1) is carried out front and back hook brush pellet with the hook that various special steel disc is made with various flute profile and prizes sub cooperation with one, reaches pellet parallel divisional in lock core and unblanks.(2) utilize the upper and lower fast ram lock core marble of special instrument, or the instrument object producing similar key knocks and allows rapid movement before and after special key, utilizes and reaches when Tooth or concave point clash into pellet object of unblanking.(3) instrument similar to key is manufactured, spread with the softer object such as tin sheet above, then rotate about, certain dislocation is had when utilizing lock core marble separately to intersect, to such an extent as to lock core marble puts in place no longer flexible, and gravure is extruded on tin sheet, reach the same with the key profile of tooth depth, thus reach object of unblanking.

In a word except unblanking by force, no matter any instrument is all utilize lock core marble be separated up and down and manufacture, and the design prevents these leaks exactly and allows those except me, and how no matter others be difficult to carry out is unblanked.

On market, major mechanical lock is all turn on lock core just to equal to open whole lock, so present various security door is all that a consideration lockset is firm with coordinating of security door, thus overstriking bolt, and add steel plate to prove that security door anti-theft feature is good, but that can only work to ordinary people, and inoperative for the people being skillful in unblanking.Given this present invention utilizes pellet to coordinate with lock core, and pellet coordinates with key, and lock body coordinates with password, ensure that property safety and the social security of owner.

Summary of the invention

The present invention is intended to the defect overcoming prior art, and lock core structure utilizes salient point to manufacture concave point combination salient point and salient point, adopts several pellet to cooperatively interact.Provide a kind of rational in infrastructure, chain lock that safety is high.

In order to solve the problems of the technologies described above, the invention provides following technical scheme:

Chain lock, comprise key, lock core, lock body, described lock body side is fixedly installed lock panel, lock panel has town tongue apertures and three keeper post holes, lock body front is provided with the lock core in lock core hole, in lock body, combination disk is installed, combination disk unlock chip, door handle cam set, town tongue, lock latch and lock cam, combination disk is in transmission connection by gear train and lock core, combination disk also by linking springs with lock latch and be connected, lock indentation, there on the downside of latch to be provided with and to lock cam, combination disk unlock chip is fixedly installed in lock body top, be provided with inserting column on the downside of combination disk unlock chip and insert combination disk, tongue one end, town is connected with the door handle cam set of rotation, door handle cam set is connected with the keeper post of three integral types, key front end is inserted in the key hole of lock core, tongue of unblanking is inserted with in key, positioning cross frame is connected with between in the middle part of lock core, positioning cross frame outer setting has gear, all jump ring is installed between positioning cross frame and two-phase lock core, bottom lock core, side is provided with lock core marble and spring.

Further, combination disk is provided with fixing hole and a locking plate groove.

Further, gear train is made up of two intermeshing travelling gears.

Further, key is convex, and key back-end central has tongue hole of unblanking vertically, and key forward plane is provided with key pellet and concave point tooth, and key pellet is the copper sheet being welded with steel column, with spring in the middle of steel column.

Further, tongue of unblanking is T font.

Further, lock core marble is more than one I shape pellet.

Compared with prior art, the present invention has following beneficial effect:

Chain lock is rational in infrastructure, the key position that namely lock body locks a door, and adopts coded lock to coordinate with bolt to prevent violence from unblanking, enhances theftproof performance.
