Abstract
The utility model relates to an adjustable cipher cylinder lock, which is composed of a lock casing and a lock core. Digital keys are arranged on the lock casing, the lower parts of the digital keys correspond to a lock core cylinder (a straight gear cylinder) and a soleplate cylinder, and the straight gear cylinder is divided into a long straight gear cylinder and a short straight gear cylinder or is also provided with a middle straight gear cylinder. The digital keys corresponding to the short straight gear cylinder are cipher keys, and the number and the position of the cipher keys can be set or changed according to users' need. The utility model has the characteristics of simple structure and convenient operation, does not use the key when the lock is unlocked, and is an ideal necessary in modern life.
Description
The utility model relates to a kind of cylinder lock, especially relates to a kind of adjustable cipher cylinder lock that need not be key operated.
At present, the common spring lock is to be made of lock housing, lock core, pellet shot from a slingshot and spring, and it is to utilize the height of shaped as key bit to make when a row pellet shot from a slingshot different in size just in time is in the plug face position in the lock core, and screw key drives lock core and rotates and lock is opened.Not right as shaped as key bit, the lock core marble of different length just can't be in the plug face position, and lock just can't be opened.This marble lock key need be carried, and is very inconvenient; In case and key loss, will bring unsafe hidden danger.For safety, often need the tapered end more renew again, thereby cause unnecessary waste.
It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and unblanks without key, and can arbitrarily change the adjustable cipher cylinder lock of password as required.
The utility model is to be made of lock housing and lock core two parts, be provided with the set of number button at the lock housing upper surface, lock housing cavity inner bottom surface is provided with base plate, is distributed with on the base plate and the corresponding base plate pellet shot from a slingshot of digital keys quantity location of equal, is provided with step-by-step pin or spring in the lock housing side.Lock core is positioned at the base plate top of lock housing cavity, by position adjustable board, location-plate and pressing plate constitute cylinder plate, cylinder plate is provided with vertical blocking marble, each corresponding digital keys in vertical blocking marble top, the corresponding base plate pellet shot from a slingshot in below, vertical blocking marble are divided into long vertical blocking marble and short vertical blocking marble, and the digital keys of short vertical blocking marble correspondence is a password key.Be provided with in the middle of the cylinder plate and carry a bar and steel ball, steel ball is positioned at the end of carrying a bar, and it is external that the other end of carrying a bar extends to lock shell cavity, forms and carry a button, can be for pushing.
The utlity model has simple in structure, make easily, easy to use, theftproof is strong, unblanks without key, and can change the advantage of password as required at any time.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the lock-shell structure schematic diagram
Fig. 3 is the lock core structure schematic diagram
In order to make the utility model structure clear more complete, the utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, the utility model is to be made of lock housing and lock core two large divisions, is provided with digital keys 12 at the upper surface of lock housing 11, is provided with below digital keys 12 by key spring 14 and button screw rod 13.On base plate 18, have the pellet shot from a slingshot hole, be provided with base plate spring 20 and base plate bullet in the hole, base plate 18 is fixed on the bottom surface of lock housing 11 cavitys with solid word bolt 16 in 19.Be provided with one piece of step-by-step pin 15 (also can adopt spring) in the side of lock housing 11.
The course of work of the utility model coded lock is as follows: when shutting, push and carry a button 1, promotion is carried a bar 2 and is moved inward, under the effect of putting forward a bar 2 end chamfer, with steel ball 10 jack-up, steel ball 10 is again with position adjustable board 8 jack-up, make the vertical blocking marble (6.9) on the lock core all be promoted to sustained height, a button 1 is carried in relieving, carrying a bar 2, steel ball 10 and position adjustable board 8 resets, but, make vertical blocking marble 6,9 under the situation of no external force effect, can remain on sustained height owing to adopt the wear-resisting acrylonitrile-butadiene rubber of oil resistant to make location-plate 5.This duration vertical blocking marble below is just in time concordant with lower platen 7-2, and the base plate pellet shot from a slingshot 19 of short vertical blocking marble 9 belows stretches in the cylinder plate under the effect of base plate spring 20, and lock core just ejects dead bolt.Make lock be in locking-in state.The pairing digital keys 12 in short straight shelves pellet shot from a slingshot 9 tops is password key 12-1, and the quantity of password key 12-1 and position can be provided with or change as required.When unblanking, push password key 12-1, button screw rod 13 promotes short vertical blocking marble 9, the base plate pellet shot from a slingshot 19 that stretches into lock core is pushed back in the base plate, because of oil resistant rubber location-plate 5 plays positioning action, make short vertical blocking marble 9 be pressed in base plate pellet shot from a slingshot 19 in the base plate tightly, make the interior base plate pellet shot from a slingshot of vertical blocking marble and base plate in the lock core not have mutual dislocation, push step-by-step pin 15 then, it is external that lock core is ejected lock shell cavity slightly, dead bolt is rebounded, and lock has just been opened.
When unblanking, if do not know password, non-password key 12-2 is depressed, the button screw rod 13 of then non-password key 12-2 belows has promoted corresponding with it long vertical blocking marble 6, and long vertical blocking marble 9 is stretched in the base plate on the contrary, stings tightlyer on the contrary between lock core and lock housing.
, be provided with the length vertical blocking marble in addition, also can establish in one piece vertical blocking marble as the location password except that above-mentioned according to one, the numeral of the pairing button of this pellet shot from a slingshot, necessarily as last figure place of password, should change the step-by-step pin 15 of lock housing side into spring this moment.When lock was closed condition, its function was consistent with short vertical blocking marble.When unblanking, press other short vertical blocking marble after, lock still can not be opened, and in pressing straight pellet shot from a slingshot half just to and the concordant place of lower platen 7-2, step-by-step pin 15 place's springs are upspring, lock leaves.If press middle vertical blocking marble earlier, its function is similar with long straight retaining, directly stretches in the bottom plate hole, makes lock core still can't unblank with the base plate interlock, in like manner can push again and carry a key, make vertical blocking marble carry the position again after, be pressed into correct number and unblank.
