Description
Technical field
The utility model relates to field of lockset technology, refers in particular to the magic engineering AMB lock core that a kind of security protection rank is high.
Background technology
AB key lock, it has A, two kinds of keys of B.It is that key is beaten " hole ", a kind of lockset being comprised of structures such as pellets (depth in hole is different, is the same from the shallow different reason of depth of threat of flat key).Also have and be " click lock " and " computer lock is " step lock " and " Brix lock " in addition.The effect of A, B key is: when people load onto after this lock, owner can give A key house decoration personnel, passes in and out house door and unblanks, so also claim A key for " finishing key " for them.After finishing, it is indoor that owner does not need finishing personnel to enter, and owner injects lockhole rotational lock core one with B key and turns after (circle), and A key has just lost the function of unblanking, so B key is also " house-owner's key ".The advantage of AB key lock is the needs that can meet people's decorating house, remove from when finishing is acted hurriedly in a messy situation, the key loss of opening the door, or there is the people who harbores evil intentions to take advantage of the busy machine of finishing to copy the key etc. that opens the door, may avoid the unsafe factor after finishing, owner being produced, also can avoid, after finishing, for safety, changing trouble and cost that lock strap is come, so welcomed by the people.
Current its key of AB key lock is, by tartar, A, B key are set, conventionally A, B key differential be 3～4 values differential (as A key tooth flower: 543251, B key tooth flower: 143251 or 243251); On arranging, pellet adopts the steel ball of respective stages difference or the level difference that short upper pellet is filled up A key, after B key turns 360 degree, be used for filling up the steel ball of level difference of A key or other position or the key back that pellet moves to lock gall, so A key and cannot opening.
Because above-mentioned technical condition are mentioned in arranging, fixing while allowing the variation of level difference of key tooth flower, along with product is sold in enormous quantities, some locksmiths or relevant technician are studied it, and clone very soon B key (normally increasing a pad (1.5mm 2.0mm) on the dark tooth of A key value just can open AB key lock), cause the anti-theft feature of existing AB key lock greatly to reduce.
