Abstract

The utility model discloses a linked double-lock core lockset and a key. The linked double-lock core lockset is characterized in that a main lock core (8) and an auxiliary lock core (2) are mounted at two ends of a lock head; a row of tooth racks are arranged on one side where two movable tooth racks (7) are connected with a driven gear (6); and the rows of tooth racks are mounted in grooves on the upper and the lower sides of the driven gear (6). The locking and the unlocking of the main lock core (8) are realized in such a manner that the auxiliary lock core (2) drives a drive gear (5) to rotate, the drive gear (5) drives the driven gear (6) to rotate, and the driven gear (6) drives the movable tooth racks (7) meshed therewith to move, so as to clamp or unclamp the clamping position (9) of the main lock core. The key adopts the design of an inner key and an outer key, wherein the inner key (13) is concealed in the outer key (11) so as to be combined into a key. The inner key and the outer key can be combined or separated through a clamp spring (14) on a key handle; the main lock core can be unlocked only by unlocking the auxiliary lock core rightly; the auxiliary lock core can be unlocked only through the operation in the opposite direction completely according to the preset locking turning number; otherwise, the unlocking can not be realized; and the preset locking turning number also can be changed at any moment. The key adopts the unique design of the inner key and the outer key, the inner key is concealed in the outer key so as to be combined into the key in normal times; and the inner key and the outer key be combined or separated through the clamp spring on the key handle. The utility model enhances the difficulty of technical unlocking, and the time required for unlocking, and reduces the re-unlocking rate of the lockset, thereby achieving safer and more reliable operation.

Description

A kind of coordinated type twin-lock core lockset and key
Technical field
The utility model relates to a kind of lockset, promptly a kind of coordinated type twin-lock core lockset and key.
Background technology
In order to prevent that property from being stolen; people use various locksets to protect the safety of self property; but most lockset all just adopts the design of monolock core; easily by technology unlocking; safety is not high; people need more safe and reliable lockset to satisfy the demand; the lockset industry presses for towards the direction of anti-technology unlocking and develops simultaneously; and coordinated type twin-lock core lockset adopts twin-lock core interlock design; increase the difficulty of technology unlocking and required time greatly in conjunction with unique inside and outside spoon design and method for unlocking; reduce lockset reopening rate, more safe and reliable, more can satisfy people's demand.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of can effectively prevent technology unlocking, reduces the lockset and the key of reopening rate.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of coordinated type twin-lock core lockset and key, comprise main lock core, auxiliary lock core driving gear, driven gear, movable tooth bar in the tapered end, it is characterized in that auxiliary lock core does not have directly main lock core not to be locked or unlock, but rotate by driving driving gear, driving gear drives driven gear and rotates, the movable tooth bar that utilizes driven gear to drive again to be engaged with blocks or does not block the main lock core screens and realizes the locking of main lock core or unlock when moving, and the inside and outside spoon design of key.
The main lock core of described coordinated type twin-lock core lockset and key, auxiliary lock core, driving gear, driven gear, movable tooth bar all is installed in the same tapered end, auxiliary lock core passes through driving gear, driven gear, movable tooth bar is realized locking and the releasing to main lock core, the some circles of revolute pair lock core when locking, auxiliary lock core gear driven driving gear, the driven gear activity, two movable tooth bars are moved simultaneously round about, one is retracted in the groove, one is stretched in the main lock core screens, the locking main lock core, counter-rotation auxiliary lock core same number of turns during release, movable tooth bar resets, and returns released state.In rotate or few revolute pair lock core, two movable tooth bars any can be blocked the main lock core screens more, the locking main lock core, thus can not release.Key and outer key in described key is divided into, interior spoon ensconce be combined in the outer spoon one key combined, can realize combination or separate by the jump ring on the shank of the key.
The beneficial effects of the utility model are: the utility model adopts twin-lock core interlock design, can only open the release of major-minor lock core ability in order, open the method for auxiliary lock core can only be fully when locking the reverse operation of predefined path just can unblank, increase the difficulty and the time of technology unlocking, more safe and reliable, the reopening rate of unique inside and outside spoon design reduction lockset.The utility model is applicable to any mechanical lock, can be applicable to anti-theft lock for motorcycle, anti-theft lock for bicycle, and automobile anti-theft lock, various fields such as household lock, range of application is very extensive, and the utility model is simple in structure, and is with low cost, is fit to large-scale production and promotes.
Description of drawings
Below in conjunction with accompanying drawing and enforcement the utility model is further specified:
Fig. 1 is the utility model auxiliary lock core schematic diagram that unlocks.
Fig. 2 is that the utility model auxiliary lock core locks schematic diagram to main lock core.
Fig. 3 is the utility model key schematic diagram.
The specific embodiment
With reference to figure (1), (2), (3) auxiliary lock core (2) to main lock core (8) disarm state under, outer spoon (11) is inserted the some circles of auxiliary lock core hole (3) revolute pair lock core (2), auxiliary lock core gear (4) just drives driving gear (5), driven gear (6) rotates, in a retraction groove in two movable tooth bars (7), one is stretched into and blocks main lock core (8) in the main lock core screens (9) and just finish locking to main lock core (8), the state shown in figure (2); Same number of turns when equally outer spoon (11) being inserted auxiliary lock core hole (3) counter-rotation auxiliary lock core (2) and locking rotation during release, auxiliary lock core gear (4) just drives driving gear (5), driven gear (6), the movable tooth bar (7) that stretches in the main lock core screens (9) is resetted, releasing is to the locking of main lock core, state shown in figure (1), press the jump ring (14) on the shank of the key then, jump ring (14) breaks away from jump ring position (12), take out the interior spoon (13) of ensconcing in the outer spoon (11), be inserted in the main lock core hole (10) and just can rotate main lock core (8), open lockset.When if the number of turns that the number of turns of revolute pair lock core (2) is set when locking during release is inconsistent, in two movable tooth bars (7) any all can stretch in its corresponding main lock core screens (9) and block main lock core (8), make main lock core (8) not rotate, thereby can not open lockset.
