Description

Key and lock with adjusted marble number

The utility model relates to a kind of lock of being made up of adjustable pellet shot from a slingshot number key, adjustable coded ball lock core and tapered end.It has both been maintained secrecy, and is user-friendly to again, for security personnel's start or stop of the mobile big hotel door of user and all kinds of case, cabinet, table, car, ship, gate, provides good practical function especially.

Existing cylinder lock is to insert lock core by the key bit that is shaped on the length injustice, cooperates the length pellet shot from a slingshot in the lock core, and the circumferential surface that forms lock core is smooth, lock core can be rotated in tapered end to the left and right and finishes the unlatching security personnel effect that is locked in all kinds of doors.Because pellet shot from a slingshot and key bit in the existing cylinder of spring lock can not change arbitrarily, thereby have just formed a kind of key of profile of tooth, can only fix the defective of opening a lock.

The purpose of this utility model is the lock that a kind of adjustable pellet shot from a slingshot number formula key, adjustable pellet shot from a slingshot number formula lock core will be provided.It has not only possessed the advantage of existing cylinder lock, and its security personnel's effect is brought up to and needed the just chance (referring to 15 7 spring types) that repeats of number once 6435 times.And users only need one the adjustable pellet shot from a slingshot number formula key of same specification, as long as know the pellet shot from a slingshot number numbering in the lock core, just can open the lock of all same specifications.Because the pellet shot from a slingshot number that the user can change arbitrarily in two, three minutes in the lock core is numbered, as long as so the user remember, to hang over pellet shot from a slingshot number in the lock core on the limit just can after door is closed, the pellet shot from a slingshot number of layout on the key be dialled unrest.Thereby solved key and be afraid of to lose, be afraid of worry imitated by other people, that must carry.In addition, system key producer is because of only needing the key of a kind of specification of system, so just can save a part of production process.Simultaneously, also, just need not rotate and lock can be opened, so can key made of plastic and pellet shot from a slingshot on the key because the utility model key when unblanking, only needs key is inserted lock core.So just saved a large amount of non-ferrous metals for country.

The utility model is realized as follows: key is with rectangular laminar plastics or metal horizontal space groove (as E shape space groove wherein).In groove, pack into 3～30 unified specifications, conical, can stir and be arranged in the E shape groove key pins (using 7 pellets shot from a slingshot here) of forming each sets of numbers.Pellet shot from a slingshot in the key stirred in each groove encode, inserted-shape is in the key mouth in the rectangular bluff body lock core then, allow wherein 7 short pellets shot from a slingshot of 6～60 T shape pellets shot from a slingshot (using 15 here) that key pins jack-up packs in lock core T shape shell hole, and can make in the shell hole remaining 8 grain length pellets shot from a slingshot under the situation that does not have key pins jack-up, pellet shot from a slingshot major part disc also can equally with short pellet shot from a slingshot major part disc be arranged in parallel within the contact surface of lock core and tapered end, make 6～60 (using 15 here) T shape pellets shot from a slingshot of packing in the tapered end T shape shell hole (wherein 7 short pellets shot from a slingshot and 8 grain length pellets shot from a slingshot, they are to be enclosed in brokenly in 15 tapered end shell holes, and suppressed in the tapered end shell hole by spring) not because be and lock core marble, the same center of circle of key pins, when lock core moves forward and backward in tapered end, and by lock core shell hole or tapered end bundle that shell hole blocks.Do not prick phenomenon because lock core has card, thereby when key inserts lock core, lock core integral body will withdraw from tapered end (because the pull bar that the pull bar head is linked into an integrated entity in the velamen lock body that lock core is installed is later tightly ejected by spring) automatically to a kind of length.When pull bar ejects lock core, also dead bolt is drawn in lock body, thereby finished the unlatching effect that is locked in all kinds of doors.

It is simple that the utility model changes lock medium size code operations.As long as the limited screw of tapered end outside is screwed out, set the pellet shot from a slingshot in the key correctly back by original known number in the lock core and insert lock core, lock core is all pulled out, again 7 in the lock core short pellets shot from a slingshot and 8 grain length pellets shot from a slingshot are changed arbitrarily, remember the number of 7 short new layouts of pellet shot from a slingshot in the lock core, again key is extracted lock core, and 7 pellets shot from a slingshot are on the key pressed the number of layout in the lock core, set correctly on the key number position identical in each groove for every.After setting correctly, key is inserted lock core, and all be pushed in the tapered end, screw on limited screw, so just finished the requirement that changes number in the lock together with lock core.
