Description
Technical field
The present invention relates to the lock core of a kind of preventing techniques unlatching and supporting key thereof.
Background technology
The technical unlocking of lock core, open also known as non-injury, namely under the prerequisite not making a mess of door lock and lock core, door lock or security door are opened, the lock core that existing preventing techniques is opened, also known as super B level lock core or C level lock core, super B level lock core key is mostly plate, spoon groove is one side or two-sidedly has two row's spills to add S shape, or milling groove structure in inside and outside pair of snake type, although its safety is reliable, but it is all comparatively complicated to there is structure, composite defect is difficult to after key loss, and the patent No. is disclose the lock core of a kind of preventing techniques unlatching and supporting two-segment key thereof in the patent of invention of 200810162946.2, structure is comparatively simple, also can realize the function that preventing techniques is opened with traditional tartar type key simultaneously, but there is the defect that two-segment key easily ruptures, still can not satisfy the demands of consumers.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of structure simple, safe and reliable and preventing techniques opens the lock core and supporting key thereof that effective preventing techniques opens.
For solving the problems of the technologies described above, the present invention is by the following technical solutions: the lock core that preventing techniques is opened and supporting key thereof, comprise plug body and key, described plug body comprises lock core shell, lock core overlaps and plug body described in lock cylinder is also provided with lock core sleeve between lock core cover with lock core shell, described lock core puts and is provided with upspring breach and interior inserted sheet of outer inserted sheet and upsprings breach, described outer inserted sheet breach of upspringing is positioned near keyhole insertion end, described interior inserted sheet breach of upspringing is positioned at away from keyhole insertion end, and interior inserted sheet is upspring, breach is larger than outer inserted sheet breach of upspringing, described lock cylinder comprises lock core body, outer inserted slot, interior inserted slot and inserted sheet, described outer inserted slot and outer inserted sheet breach of upspringing is corresponding, described interior inserted slot and interior inserted sheet breach of upspringing is corresponding, described lock core body is provided with key insertion hole and unlocking mechanism, lock core body is provided with guide-track groove near key insertion hole one end, described guide-track groove is provided with the key insertion hole block slided along guide-track groove, described key insertion hole block is provided with breach, projection and projection, the size of described breach is less than or equal to projection, described lock core sleeve is positioned near key insertion hole insertion end, lock core sleeve is provided with through hole near the side of key insertion hole insertion end, through hole outward flange is provided with guide groove between lock core sleeve outward flange, described guide groove has the outer peripheral solstics of close lock core sleeve and the close outer peripheral closest approach of through hole, described projection and guide groove match and merge along guide groove activity, the described inserted sheet be provided with on the key in two groups of outer inserted slots of the corresponding unlocking spring lock core of tartars difference and interior inserted slot, also be provided with side notch and port on the key, after key inserts plug body, the cooperation corresponding with the breach on key insertion hole block of described side notch, the cooperation corresponding with the projection on key insertion hole block of described port.
The beneficial effect of the lock core that preventing techniques provided by the invention is opened and supporting key thereof is: plug body is also provided with lock core sleeve between lock core cover and lock core shell, and be provided with through hole at lock core sleeve near the side of key insertion hole insertion end, through hole outward flange is provided with guide groove between lock core sleeve outward flange, described guide groove has the outer peripheral solstics of close lock core sleeve and the close outer peripheral closest approach of through hole, and key insertion hole block is set realizes key insertion hole block by the upper through hole of the key insertion hole on lock core body and lock core sleeve along guide groove activity and block, the instrument that preventing techniques is opened inserts, concrete implementation procedure is: when after plug body locking, the instrument of technical unlocking is adopted to insert key insertion hole, and rotational lock core main body, now inserted sheet be in lockup state can not directly completely rotational lock core main body and opened lock, due to the difference of inserted sheet individuality, at least have an inserted sheet and lock core overlap between be resisted against outer inserted sheet that lock core overlaps at first upspring breach side along with rotating, again by provoking this slice inserted sheet, move it opening, because this inserted sheet and outer inserted sheet breach side of upspringing leans, this inserted sheet can be made to remain on opening, and then go to provoke second and to upspring the inserted sheet that breach side leans with outer inserted sheet, second inserted sheet is made also to move to opening, all inserted sheets that breach of upspringing with outer inserted sheet the most at last matches all move to opening, thus crack all inserted sheets that outer inserted sheet upsprings on breach, and lock core body is rotated, and the interior inserted sheet of lock core cover breach of upspringing is larger than outer inserted sheet breach of upspringing, therefore the upspring inserted sheet of gap position of interior inserted sheet now can not be resisted against interior inserted sheet and to upspring the side of breach, cannot by provoking the inserted sheet that in lock core cover, inserted sheet is upspring in breach, reach and inserted sheet is resisted against interior inserted sheet and upsprings the side of breach, thus make the upspring inserted sheet of gap position of interior inserted sheet be held open state, finally open lock core body, and need rotation lock core body certain angle, make interior inserted sheet upspring the inserted sheet of gap position can be resisted against interior inserted sheet upspring the side of breach could technical unlocking lock core body, but at rotation lock core body and enable interior inserted sheet upspring the inserted sheet of gap position be resisted against interior inserted sheet upspring breach side process in, key insertion hole block moves along the guide groove of lock core sleeve from the solstics of guide groove to closest approach under the drive of lock core sleeve, the upper through hole of the key insertion hole on lock core body and lock core sleeve is blocked by key insertion hole block gradually, in this process, the projection of key insertion hole block and breach are in tandem, vertical and key direction of insertion forms whole and finally keeps off dead whole key insertion hole, make the instrument of technical unlocking cannot insert key insertion hole and remove technical unlocking lock core, finally reach the function that preventing techniques is opened, and when removing opening lock master with supporting key provided by the invention, tartar on the key opens inserted sheet, side notch on the key can for the breach of key insertion hole block when key insertion hole block blocks key insertion hole, do not affect the rotation of key, same port on the key is also in order to the projection of key insertion hole block can insert this port, thus do not affect key turns, therefore, it is simple that the lock core that preventing techniques provided by the invention is opened and supporting key thereof have structure, light, reliable and the feature of good damping effect.
The lock core opened preventing techniques provided by the invention below in conjunction with drawings and Examples and supporting key thereof are further described in detail.
