Description
Technical field
The present invention relates to a kind of lock core, particularly a kind of accurate anti-theft security lock core.
Background technology
Most lock core can not anti-technical opening in the market, does not have anti-theft function.Especially unlocking technique development in recent years; general lock core is opened for several seconds; even much also very easily to be unlocked by the lock core of the B of Ministry of Public Security level certification; conventionally, under, as long as the hoodle touching in lockhole by instrument just can be opened lockset, safety is very low; for head it off; the present invention designs this structure, meets the needs in market, protection client's safety of life and property.
Summary of the invention
In order to solve the problem of prior art, the invention provides a kind of accurate anti-theft security lock core, it can realize Bidirectional locking, avoids simple tool under prior art just can open the deficiency of lockset.
The technical solution adopted in the present invention is as follows:
A kind of accurate anti-theft security lock core, comprise lock housing, in described lock housing, be provided with lock gall, in keyhole in lock gall, be provided with twin body pellet, described twin body pellet top interlock has vertically mechanism, and described twin body pellet one side has groove, and described groove coordinates inlay card with the level plug rake locking mechanism being interspersed in lock gall, described twin body pellet lower end is tapered, and it can be used in conjunction with the boss portion of key.
Twin body pellet inner side is provided with steel ball, the described twin body pellet of described steel ball top interlock.
Vertically mechanism comprises the envelope pearl of being fixed in lock housing, described envelope pearl below connects flat pearl by pearl spring, the upper end of the described twin body pellet of lower end interlock of described flat pearl, described flat pearl, pearl spring and Feng Zhujun is arranged in the sliding eye of lock housing top, the steel ball that described twin body pellet interlock is described and level plug rake locking mechanism.
Level plug rake locking mechanism comprises the plug rake being interspersed in lock gall, described plug rake outside is resisted against in the plug rake groove of inwall of lock housing, the groove that open with described twin body pellet one side the inner side of described plug rake coordinates inlay card, and described plug rake two ends are provided with and make the automatically reset plug rake of plug rake spring.
Twin body pellet is at least 2, a steel ball of each twin body pellet coupling.
The accurate safety anti-theft lock core of one of the present invention, comprise lock housing, in lock housing courage hole, have a plug rake groove, lock gall that can rotating 360 degrees after packing correct key in lock housing into and inserting, above lock gall, be provided with one group of twin body pellet and take hole in, twin body pellet can freely move up and down in marble hole.Lock gall one side is provided with plug rake groove, in plug rake groove, has plug rake, and two plug rake springs.
The present invention adopts the opening and closing of the plug rake co-controlling lock core of one group of twin body pellet and one group of steel ball and side, also can be only by the unlatching closure of the plug rake control lock core of one group of twin body pellet and side
Twin body pellet can play controls flat pearl and side plug rake Bidirectional locking open function.
One group of steel ball mainly plays to be controlled twin body pellet and then controls and open closed effect, and steel ball also can play the effect that prevents that lock core from being destroyed by drilling in addition.
Steel ball is only to realize a kind of form of controlling twin body hoodle, also can adopt the twin body pellet of other mode controls.Or directly remove similar steel ball structure, open closed by twin body pellet and the one-sided tooth control of key.
The beneficial effect that technical scheme provided by the invention is brought is:
1, can realize Bidirectional locking, when incorrect key or foreign matter are opened, flat pearl or I-shaped pearl locking lock gall, another side is filled in rake locking.This structure can effectively prevent technical opening, in the time instigateeing in hoodle or foreign matter insertion lock gall, while encountering steel ball, steel ball ejects twin body pellet, makes to move and pin lock housing or the flat pearl of insufficient height on twin body pellet, and flat pearl or I-shaped pearl are pinned lock gall, and due to twin body pellet square groove malposition, stop the retraction of plug rake, plug rake pins lock housing, and lock core presents closure state.
2, accurate twin body pellet and steel ball coordinate realization to open closure function with key tooth flower height, and twin body pellet also can be realized separately unlatching closure function, and steel ball can also be realized the function that anti-violence is opened.
3, twin body pellet steel ball one side can add management pearl, realizes management function, reaches high-accuracy anti-theft lock and can do management function of key.
Compared with prior art, the present invention has the following advantages:
1, adopt one group of twin body pellet and one group of steel ball to combine, key secret key amount is large, and mutual opening rate is low.
2, key processing technology complexity, required precision precision, is difficult on market copy, and ensures user's safety.
3, twin body pellet steel ball one side is locked by flat pearl or I-shaped pearl, and side, substantially cannot technical opening by filling in rake locking.
4, twin body pellet adopts hot investment casting or the processing of other precision machine tools, and colleague is difficult to imitate, and theftproof performance is good.
