Description
Technical field
The utility model relates to a kind of lock core, particularly a kind of accurate anti-theft security lock core.
Background technology
Most lock core can not be prevented technical opening in the market, does not have anti-theft function.Especially in recent years unlocking technique development; general lock core was opened in several seconds; even much the lock core by the authentication of the B of Ministry of Public Security level is also very easily to be unlocked; usually under, need only the hoodle that touches in lockhole by instrument and just lockset can be opened, safety is very low; for head it off; the utility model designs this structure, the needs of satisfying the market, protection client's safety of life and property.
Summary of the invention
In order to solve the problem of prior art, the utility model provides a kind of accurate anti-theft security lock core, and it can realize Bidirectional locking, avoids simple tool under prior art just can open the deficiency of lockset.
The technical scheme that the utility model adopts 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 in 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 inboard 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 the 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 are arranged in the sliding eye of lock housing top, the described twin body pellet described steel ball of interlock and level plug rake locking mechanism.
Level plug rake locking mechanism comprises the plug rake that is interspersed in lock gall, the described plug rake outside is resisted against the plug of the inwall of lock housing and harrows in groove, the inboard of described plug rake coordinates inlay card with the groove that described twin body pellet one side is opened, 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, steel ball of each twin body pellet coupling.
A kind of accurate safety anti-theft lock core of the present utility model, comprise lock housing, a plug rake groove is arranged in lock housing courage hole, lock gall that can rotating 360 degrees after the correct key in the lock housing of packing into inserts, 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, the plug rake is arranged, and two plug rake springs.
The utility model 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 with 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 a kind of form that realizes controlling twin body hoodle, also can adopt other modes to control twin body pellet.Perhaps directly remove similar steel ball structure, by twin body pellet and the one-sided tooth of key, control and open closure.
The beneficial effect that the technical scheme that the utility model provides 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 the rake locking.This structure can effectively prevent technical opening, in the time of in instigateeing hoodle or foreign matter insertion lock gall, while encountering steel ball, steel ball ejects twin body pellet, makes on twin body pellet to move to pin lock housing or the flat pearl of insufficient height, 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, the 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 the key tooth flower height, and twin body pellet also can realize separately opening 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 the management pearl, realizes management function, reaches high-accuracy anti-theft lock and can do the management function of key.
Compared with prior art, the utlity model has following advantage:
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, the required precision precision, be difficult on market copy, and guarantees user's safety.
3, twin body pellet steel ball one side is by flat pearl or the locking of I-shaped pearl, and side, substantially can't technical opening by the locking of plug rake.
4, twin body pellet adopts hot investment casting or the processing of other precision machine tools, and the colleague is difficult to imitate, and theftproof performance is good.
