When stirring combination dials gear, therefore the internal gear be engaged with can start to rotate, due to the difference of gear ratio, the different internal gear of radius needs to rotate the number of turns different separately just can be made on the right of the indentation, there of the U-shaped clamp on it (be coupled by wind spring and internal gear are concentric, can rotate together, adjust can pin the motionless internal gear that makes during password rotate) unanimously turns to, at this moment sliding fast projection can enter its indentation, there, slide block discharges left, and unclamp the baffle plate to lock core, lock is opened.
Described housing be provided with three for rotate fixed password driving plate gear positioning cylinder, three for rotate fixed annulus positioning cylinder, two for rotate the positioning cylinder of fixing unidirectional buckle and two for reset side opening, one for rotating the positioning cylinder of fixed lock core.
Wind spring for storage power is connected with internal gear, and internal gear is blocked by unidirectional buckle, and therefore in the process of unblanking, for making internal gear arrive assigned address, combination dials gear needs the number of turns of rotating to be determined by gear ratio.As long as user's rotational password driving plate gear, has driven internal gear rotation, wind spring will start storage power.Because when user prepares to unblank, combination dials gear is that to rotate a fixing turn in the raw or be unascertainable.Inside and outside such as certain gear, gear ratio is 3:1.In order to be that internal gear reaches certain position, combination dials gear needs rotation three to enclose.When user prepares to unblank, he can not determine whether to have rotated a fixing turn.If rotated, then wind spring stores energy, and user only needs to click control lever and unidirectional buckle is unclamped, and wind spring starts to release energy, and interior combination dials gear is returned to initial state, i.e. the state of combination dials pinion rotation 0 circle.
Technique effect
Compared with prior art, the present invention utilizes mechanical mechanism cleverly.The process of unblanking make use of two-stage gear-linked, introduces a set of interior password by different gear ratios, utilizes the number of turns one of combination dials gear and rotation to react on the rotation of internal gear, greatly strengthen its safety.Structure of the present invention is simple, easy to manufacture, small volume, can be applicable to luggage case, the fields such as door lock.The interior password of the multi-stage gear introducing of the innovation that the present invention proposes drastically increases the quantity (adding the effect concept of the number of turns) of codon, improves the security performance of lockset.
