Description
Technical field
The utility model relates to mechanical lock technical field, is specifically related to a kind of novel anti-theft side column lock.
Background technology
Lock is the article that cannot leave in people's daily life, and the mankind use lock to preserve important article since ancient times always, make the property of oneself can not be stolen by others.The antitheft position of core of lock is exactly lock core, and the performance quality of lock core directly has influence on whole lockset theftproof performance.Current lock core of a great variety, theftproof performance is uneven, and manufacturer was for this phenomenon in recent years, have developed a lot of money lock core of good performance.
The representational structure of most is side column lock core, especially blade side column lock core.Side column lock core is divided into again interior pressure and external-compression type side column lock core.To be normal opening structure feature be its side column of inner pressed side column lock core when unblanking that side column automatically retracts in lock core under the effect of interior pressing spring unlocks.Its side column of external pressure side column lock core is normally closed structure, is to be compressed in lock core by side column by rotational lock core to unlock when unblanking.Inner pressed lock core feature is rotational lock core, and side column directly locks, and does not open lock core with omnipotent dislocation unlocking method.Its shortcoming is blade is that V-shaped coordinates with side column, and mutual opening rate is high, and easy quilt cover is opened and pushed aside.External-compression type side column lock core feature is rotational lock core, in outer side column, blade kills by pressure, blade cannot be struck, can not be opened by technical unlocking and the tool that goes into operation soon, but this structure can not prevent strong twistlock core from unblanking, press in outer side column when strong twistlock core and destroyed by blade, side column is forced to be compressed in lock core and is opened by lock.Its advantage of external-compression type side column lock is when unblanking with omnipotent dislocation unlocking method, twisting lock core blade be dial motionless, so cannot be pushed aside.But because of its structure be steel ball and side column for firmly to link, it is push back lock core by steel ball that side column is retracted, and during strong twistlock core, steel ball is by pressure direct-drive on side column, and side column is by blade compressive strain, thus lock core is easily wrestled out by force.
When the advantage of inner pressed side column blade lock is with omnipotent dislocation unlocking method unlatching, lock core locks by twisting lock core side column, and stir blade without feel, blade and side column are in full clutch state, cannot open by lock.Shortcoming is that groove is V-structure because blade side is unblanked, and when leaf spring reseting elasticity is less than side column spring pressure, need not twist lock core, stir blade side column and be easily automatically pushed in lock core, thus pushed aside.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model be to provide a kind of structure simple, increase technical unlocking difficulty, effectively prevent lock core by illegal technical unlocking, the novel anti-theft side column lock that tartar amount is many.
For achieving the above object, the utility model provides following technical scheme: a kind of novel anti-theft side column lock, comprise lock housing, key and columned lock core, the described lock housing macropore being lock housing and being provided with shape and lock core and matching, described lock core is provided with by lock housing macropore front end the keyhole that shape and key shape match, side column locking groove is provided with in described lock housing macropore, the blade lock groove communicated with it is provided with between lock housing macropore with an ancient piece of jade, round, flat and with a hole in its centre outside lock housing side, described side column locking groove rear and front end is provided with the reed side opening communicated with lock housing outer wall, described lock core sidewall is provided with vane hole, the first groove and the second groove is provided with in vane hole, vane hole communicates with keyhole, in vane hole, the first groove side is provided with outer leafs spring eye, outer leafs spring is provided with in outer leafs spring eye, described key positive and negative is all provided with key tooth flower, key tooth flower comprises left outside tartar, right outside tartar, left inside tartar and right inside tartar, the left outside blade and right outside blade that match with key tooth flower is provided with in described vane hole, described left outside blade and right outside blade include outer leafs body, spring reset boss and the outer leafs keyhole be arranged in the middle part of outer leafs body, and at least one end of outer leafs body is provided with outer leafs positive stop lug boss, outer leafs positive stop lug boss embeds with the motion of blade or exits blade lock groove, outer leafs body is positioned at outer leafs keyhole side and is provided with outer tartar boss, outer leafs body deviates from spring reset boss end and is provided with outer leafs and unblanks notch and the anti-dial lock groove of outer leafs, described outer leafs unblank notch and the anti-dial lock groove position of outer leafs all with the mating shapes of key tooth flower, the left inside blade mated with key tooth flower and right inside blade is provided with in second groove of described vane hole, described left inside blade and right inside blade include intra vane body and are arranged on the intra vane keyhole in the middle part of intra vane body, tartar boss in described intra vane keyhole side is wholely set and matches with key tooth flower, intra vane body is provided with intra vane near interior tartar boss end and unblanks notch and the anti-dial lock groove of intra vane, described intra vane unblank notch and the anti-dial lock groove position of intra vane all with the mating shapes of key tooth flower.
By adopting technique scheme, two groups of outer leafs and two groups of intra vanes of coupling corresponding with key tooth flower are distributed with in lock core, wherein outer leafs has spring, intra vane is without spring, have the outer leafs positive stop lug boss when locking of the outer leafs positive stop lug boss in two of spring groups of outer leafs to push lock housing blade lock groove to lock, key positive and negative respectively has four tartar password grooves, tartar amount is many, tartar can be solved thoroughly and open problem mutually, increase technical unlocking difficulty, effectively prevent lock core by illegal technical unlocking.
The utility model is set to further: the sidewall of described lock core is provided with side column groove, side column groove communicates with vane hole, side column that can be reciprocating is provided with in side column groove, side column the inner is provided with braking square column, braking square column the inner is provided with the anti-allocating slot of side column, the side column locking groove side of side column in lock housing is provided with side column lock deckle, and two ends, side column left and right are provided with spring return function boss, are provided with side column spring between spring return function boss and side column trench bottom; Be provided with shell fragment between described side column and side column locking groove, described shell fragment two ends are provided with V-type spring pin, and described shell fragment mid portion is provided with stationary plane, and V-type spring pin is connected with side column lock deckle, and the stationary plane of described shell fragment is connected with side column locking groove bottom.By this setting, when blade locking illegal solution is removed by side column locking, side column automatic spring normally closed locking when locking, be that the passive V-type spring pin by shell fragment compresses retraction when unblanking, and driven member spring pin lost efficacy when illegal unlatching, side column cannot be retracted unblock, and side column is provided with the anti-allocating slot of side column simultaneously, and preventing techniques is opened.
