Description
Technical field
The present invention relates to a kind of dark spoon lock core of hiding.
Background technology
Lockset is the antitheft main tool of people, one of main means of robber's crime, be exactly to set about from lockset, or with prize, pound, turn round, dial, means such as brill damage lockset, or lockset is opened with master key preparation key technological means, the former at be lock body, the latter at be lock core, the technical crime that therefore will prevent the robber effectively just must be the absolute reliable of lock core defending performance, that is to say except that corresponding key not have any technical means it is opened.
But, no matter at present be that the automotive lock rolling screen door lock produced with a letter lock core or cross lock core, safe-guard door lock, safety cabinet lock, coded lock or the like can both and be repaiied the locksmith individually by the current craftsman that unblanks (is the personnel of industry to unblank specially), opening easily with technical approach, all is to utilize to hit the pearl realization.This technical ability of unblanking produces, and also can bring the factor that causes harm, because in a single day this technology is held utilization by bad person's support, its consequence is hardly imaginable, and the deficiency of existing lock core technology also comes out thus on the other hand.Lockset (lock core) is not having under the situation of corresponding key, and it just can not be absolute reliable only just opening its shelter-forest robber effect with technology.
Produce this unblank reason of phenomenon of spoon of not having, it is the factor of divulging a secret that exists on the present lock core structure principle, as them changeless pellet shot from a slingshot hole site and spread pattern, the same model lock core, identical hole count, the pitch-row that equates and the size of their key holes, size of key or the like can both be given preparation key and skilled unlocking, and certain rules and digit basis are provided.
The lock core of state-of-the-art technology, take key eyelet position and lock core marble position alignment, the open theory of big small perforations of key and lock core marble displacement size correspondence, prevent robber's skilled unlocking crime, certain good effect is arranged, but weak point is, the equidistant pellet shot from a slingshot of the straight line of permanent position (being the pellet shot from a slingshot hole) arrangement mode and corresponding on the key the equidistant eyelet of straight line of permanent position, the factor of divulging a secret on existing is intuitively copied out the key with its identical eyelet easily; The hole location variation of its standard (contains aperture greatly
The variation of eye position) certain rules, certainty and limitation are arranged.Thereby just exist and can be supportted the factor of holding and utilizing by the people, also just exist the possibility that can be unlocked.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of simple in structure, safe and reliable hiding dark spoon lock core.The present invention is achieved through the following technical solutions:
