Abstract
The invention provides a lockset structure with sign-changing gaskets, which comprises a shell, a rotating shaft and at least one sign-changing gasket; wherein an accommodating space is formed in the shell, and one end of the shell is equipped with a key hole; the rotating shaft is sleeved in the accommodating space of the shell and is equipped with a groove seat, the groove seat is equipped with a plurality of slots, bolts are installed in the slots; the sign-changing gaskets are stacked around the bolts of the groove seat of the rotating shaft, and a through hole is installed in each sign-changing gasket, and the inner wall of the through hole of each sign-changing gasket is equipped with a plurality of grooves and a counterpoint convex part; and a convex part lock code change system is formed by means of the stack arrangement of the counterpoint convex parts of the sign-changing gaskets and high-low potential difference multiplication combination generated by the counterpoint convex parts because of the stack arrangement, and is coexisted harmoniously in an original bolt lock code change system, so that in the lockset disclosed by the invention, the change of a lock code can be increased, further, the safety can be increased, and the use function change of the lockset can be increased.
Description
Technical field
The present invention relates to a kind of lock structure, espespecially one can be melted mutually at original code-locked change system and deposit an other code-locked change system, lockset can be made to increase the change of code-locked, and then a kind of lock structure with reversion pad that the using function increasing safety and increase lockset changes.
Background technology
As, general " lock structure ", refers to shown in Fig. 1, and it includes housing 82 and axis of rotation 83, and this axis of rotation 83 is located in housing 82, and this axis of rotation 83 is provided with groove seat 831 and several slotted eye 832, includes latch 833 in its slotted eye 832; It relies on spring 842 to make latch 843 one end of lower floor be resisted against in the slotted eye 832 of axis of rotation 83, therefore makes axis of rotation 83 not rotate and reaches effect of locking; Again when inserting right key 81, the latch 833 on latch groove 811 contact upper strata, and make the latch 833 on upper strata and its contact surface of latch 843 of lower floor flush in the contact surface of lower groove seat 84 and groove seat 831, now, this key 81 of turn can rotate by driven rotary axle 83, thus reaches the effect of unblanking.
Should " lock structure " though its can reach unblank, effect of locking, but because should the quantity of " lock structure " its latch 833 fix, therefore the change of code-locked is limited, cannot rapid expansion increase, and safety is inadequate, and then causes use limited;
And for example, BP GB2385631A " Variable Tubular Lock ", refers to shown in Fig. 2, it includes housing 82a and axis of rotation 83, this axis of rotation 83 is located in housing 82a, and this axis of rotation 83 is provided with groove seat 831 and several slotted eye 832, includes latch 833 in its slotted eye 832; It is characterized in that this housing 82a is provided with projection 821, can prevent lockaid gun from unblanking by means of this projection 821, to increase safety, in addition, its locking and the operating principle of unblanking identical with above-mentioned prior art, do not add explanation at this.
Though this BP GB2385631A its can increase safety, but because should the quantity of " lock structure " its latch 833 also fix, therefore the change of code-locked is limited, cannot rapid expansion increase.
For another example, general " lock structure " buied on the market, refers to shown in Fig. 3, it also includes housing 92 and axis of rotation 93, this axis of rotation 93 is located in housing 92, and this axis of rotation 93 is provided with groove seat 931 and several slotted eye 932, includes latch 934 in its slotted eye 932; It relies on spring 933 to make latch 934 be resisted against the groove 921 of housing 92, therefore makes axis of rotation 93 not rotate, and reaches effect of locking; Again when inserting right key 91, latch groove 911 contact latch 934 and allow latch 934 depart from groove 921, now, this key 91 of turn can rotate by driven rotary axle 93, thus reaches the effect of unblanking.
Should " lock structure " though it can reach unblanks, locking effect, quantity only because being somebody's turn to do " lock structure " its latch 934 is also fixed, therefore the change of code-locked is limited, cannot rapid expansion increase, and safety is inadequate, and then cause use limited, three kinds " lock structures " as above, all rely on key 81, the latch groove 811 that 91 its degree of depth are not identical, the latch 833 that 911 corresponding length are not identical, 934, form latch code-locked change system, but its latch 833, the quantity of 934 is fixed, therefore the change of code-locked is limited, cannot rapid expansion increase, and safety is not enough, and then cause use limited.
Therefore, inventor is in view of above-mentioned disappearance, and innovative development thought by collection, concentrates on studies for many years, finally develops a kind of lock structure with reversion pad.
Summary of the invention
Main purpose of the present invention provides a kind of lock structure with reversion pad, and the code-locked that solution existing structure slightly exists changes limited problem.
For achieving the above object, the technical solution used in the present invention is:
There is a lock structure for reversion pad, it is characterized in that, comprise:
