The specific embodiment

Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, first embodiment shown in Figure 5; The lock bridge 3 that comprises lock body 2 and cooperate snap close with lock body; Lock body 2 is provided with the dead bolt 5 that moves along lock body chute 21, be located at lock body back seat 1 and can move along back seat dead bolt return overcoat 6, overcoat return spring 4 and several the digital circles 10 of dialling between lock body back seat 1 and lock body front stall 11; Several digital group of circle 10 is enclosed within on the lock body 2 successively and can rotates along lock body 2; The digital number of dialling circle is looked specific requirement and is decided, and present embodiment is set 6, is six figure place passwords; Said dead bolt 5 is provided with and the digital suitable bumping square 51 of circle 10 quantity of dialling; Each digital inner ring of dialling circle 10 is provided with square grooves 101 that cooperate with bumping square 51 activities; Dead bolt 5 rear ends and dead bolt return overcoat 6 snappings are through moving or return behind dead bolt return overcoat 6 and the overcoat return spring 4 operation dead bolts; Said lock body 2 is provided with and the digital corresponding spring ball assembly of being made up of spring 8 and ball 9 in circle 10 positions of dialling; Said number is dialled circle 10 inner ring and is provided with the deep-slotted chip breaker 102 that cooperates with ball 9, encloses 10 relative lock bodies 2 and moves radially and have and better stir effect to limit digital dialling; The surface of said lock body front stall 11 is provided with labelled notation 12, is beneficial to the digital numeral of dialling on the circle 10 and checks the number; By making things convenient for light to be used than details in a play not acted out on stage, but told through dialogues, the digital surface that said number is dialled circle 10 preferably scribbles fluorescence coating.In the present embodiment; Said adjacent number is dialled to be provided with between the circle 10 and is dialled delineation bit slice 71, and said spacer 71 is provided with the endoporus 14 that matches with dead bolt bumping square 51 and lock body profile, and spacer 71 is fixed on the lock body 2 through the pin-and-hole 13 on pin and the spacer 71; When lock body is in pinning shape body; Spacer 71 places dead bolt bumping square 51 positions, and the digital circle 10 of dialling places position between the two adjacent bumping squares, and adjacent number is dialled circle 10 by dialling delineation bit slice 71 location.Also be provided with on the said lock body back seat 1 and be used to limit the digital banking stop 73 that encloses along lock body moves axially and overcoat 6 transition of limited lock gyrus lingulais position are moved of dialling; One group of digital group of circle is spacing by banking stop 73 and lock body front stall 11, and the shape of banking stop 73 and structure are similar to dials delineation bit slice 71.

Like Fig. 1, Fig. 2, Fig. 3, Fig. 6, second embodiment shown in Figure 7; This embodiment and the difference of first embodiment are that the locate mode that adjacent number dials between the circle is different; Be that said number is dialled circle 10 1 sides with location integrated with it inner ring 72; When lock body was in pinning shape body, said location inner ring 72 placed tongue bumping square 51 positions, and adjacent number is dialled circle 10 by location inner ring 72 location.The number of this structure and first embodiment is dialled circle 10 and is dialled delineation bit slice 71 (its effect is equivalent to the location inner ring 72 of present embodiment) branch body structure relatively, and structure is more simple, and cost is lower.

When unblanking, press the password of factory setting, the digital circle 10 of dialling of rotation is checked the number one by one; At this moment; Each digital square groove 101 in-line of dialling on the circle is arranged and is alignd with bumping square 51 on the dead bolt, toward pusher dead bolt return overcoat 6, makes dead bolt behind square groove 101 and lock body chute 21, move to desired location then; The snap close that lock bridge one end breaks away from lock body ejects, and realizes unblanking.Otherwise, when lock bridge is buckled lock body, stir the digital circle mess code of dialling, this moment, the digital square groove of dialling on the circle 101 was out-of-line, stoped dead bolt to move, and realized locking.
