Description

Ten keys mechanical coded lock able to programme

The purpose of this utility model is to each family, office, the door of enterprises and institutions, strongbox, etc. provide a kind of ten keyboard-codings that have, the high secret agreement amount mechanical code lock of replaceable unlatching password under opening.This lock also is provided with overpressure protection device and the anti-saw function of dead bolt.

The coded lock able to programme of existing machinery structure, password store to be by the storage of bent axle counting, and complex structure, precision, volume are big.As increasing the secret agreement amount, need overstriking lengthening bent axle, complicated structure makes the volume of lock increase with several times, and common house door and strongbox, cabinet can't be installed and used at all, so five number button can only be set.We declared 94,2 in 94 years, Z8781,9 patents are exactly this type of lockset, and the secret agreement amount is below ten thousand times.Gear, tooth bar that the utility model ten keys mechanical coded lock able to programme is made by steel sheet are formed establishment, stocking system, and be simple in structure, volume is little, and 0-9 the full element of number button arranged profit and made up, and the secret agreement amount is more than 1,000,000 times.Be used on various timbers, security door, strongbox, the safety cabinet safe and reliable, easy to use, decode extremely difficultly, overpressure protection device in the lock and the anti-saw of dead bolt function have prevented to open very much the raising defence capability effectively.

The purpose of this utility model is to realize like this.

The face of lock has 0-9 number button, and unlatching and programming password are used.Transmission mechanism and stocking mechanism are arranged in the lock box.Stocking mechanism is by the stamping forming gear of 2mm steel plate, and tooth bar is formed.Be locked under the opening, unload locking closure, throw off clutch plate, press first number button, this number drives the carry driving wheel by transmission mechanism and the carry driven pulley rotates a tooth position simultaneously.Because the interlock between gear, counter wheel and position-limited wheel also rotate a tooth position, counter wheel is noted and is passed to the storage tooth bar with the bond number of pressing and stores, there is a breach then to leave zero-bit on the position-limited wheel, in order to stop retreating of stiffener, for the second time press number button, in like manner, also with second password record, also promote previous carry driven pulley and position-limited wheel simultaneously and enter a tooth position again.Press two or more number button simultaneously, (also must be same during unlatching by method can) rotated, write down to corresponding gear train then simultaneously as carry, reaches storage tooth bar place at last and gather.The clutch plate that resets is loaded onto locking closure, and new password is enabled.During unlatching, press the number of number button, in proper order, method must be in full accord, otherwise the breach of position-limited wheel is out-of-line, stops stiffener to drive dead bolt and retreats.As opening by force, torsional moment surpasses 10Kg power, and the overpressure protection device zero load of being made up of spring and the steel ball lock that trackslips is not opened, and the interior mechanism of protection lock is not damaged simultaneously.

Figure one is a section of structure of the present utility model, and describing this reality in detail below in conjunction with figure one has novel concrete mode of occupation.

Open this coded lock, the key that at first will lock inserts lockhole up time meter direction and revolves (about 15 degree) zero clearing, has prevented that the people from once pressing number button.Press number button (16) according to the program of stored password, number button (16) presses down adjusting rod (15) and key card (17), make transmission carry card (12) half way around moving, the salient angle of transmission carry card (12) is stirred carry driving wheel (8) and carry driven pulley (9) (coaxial), makes it rotate a tooth position.Counter wheel (11) and spacing number (6) also rotate the respective teeth position, and drive (10) order storage tooth bar (14) withdraws from first storage number simultaneously.Left alone without help pressing, spring (13) resets transmission carry card (12).In like manner, successively by the key of checking numbers (16), it is zero that storage tooth bar (14) moves back, and the breach of position-limited wheel (6) is on same straight line.Be rotated counterclockwise key or hold, drive dead bolt (1), guide rail plate (3) and stiffener (4) breach, the lock unlatching by position-limited wheel (6) by driving shaft (20) in (21).Press wrongly midway, gently revolve the key zero clearing more clockwise, from the beginning according to number key is opened.As opening counterclockwise by force, torsional moment surpasses the stress that gives of stage clip (19), and cutting ferrule (22) compressing steel ball (18), stage clip contract in (19), key or handle (21) idle running, and dead bolt (1) can not retreat, and locks not open.

The method of changing lock unlatching password is as follows:

Under the lock opening, unload locking closure (2), pulling clutch plate (5), clutch plate (5) drives gear interlock between spacing swinging (6) disengagement and carry driven pulley (9) (clutch plate (5) coexists with position-limited wheel (6) on the axle (7)), press number button (16) successively by the program of oneself imagining, position-limited wheel this moment (6) is motionless, and programming finishes, the position of clutch plate (5) resets, position-limited wheel (6) and carry driven pulley (9) interlock are again loaded onto locking closure (2), zero clearing, the number of changing finishes, and enables new digit and opens.

Parts such as transmission of the present utility model, counting, storage are thin plate frame for movement, simplify the shaft type of Current Password lock, numerous and diverse structure of Cylinder, though the combination of 10 figure places stores, opens, volume is the same with common door lock, and is interchangeable.The secret agreement amount of the permutation and combination of 10 elements is 3628800 times, and its 0 formula is p _n=A ^h _n=n! The volume that has solved mechanical code lock is big, the difficult problem that the secret agreement amount is low.Greatly improved the anti-ability of unloading of common door lock.
