Description

Prevent the lock core of technical unlocking and supporting key thereof

Technical field

The utility model relates to a kind of lock core of technical unlocking and supporting key thereof of preventing.

Background technology

The technical unlocking of lock core, claim again nonviolent unlatching, under the prerequisite of not making a mess of door lock and lock core, door lock or security door are opened, the existing lock core that prevents technical unlocking, claim again 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 exist structure, after key loss, be difficult to composite defect, and a kind of lock core of technical unlocking and supporting two-segment key thereof of preventing disclosed in the patent of invention that the patent No. is 200810162946.2, structure is comparatively simple, also can realize the function that prevents technical unlocking with traditional tartar type key simultaneously, but exist the easily defect of fracture of two-segment key, still can not satisfy the demands of consumers.

Utility model content

Technical problem to be solved in the utility model is: provide a kind of simple in structure, safe and reliable and prevent the lock core that prevents technical unlocking that technical unlocking is effective and supporting key thereof.

For solving the problems of the technologies described above, the utility model is by the following technical solutions: prevent the lock core of technical unlocking and supporting key thereof, comprise plug body and key, described plug body comprises lock core shell, described in lock core cover and lock cylinder, plug body is also provided with lock core sleeve between lock core cover and lock core shell, described lock core puts and is provided with outer inserted sheet breach and the interior inserted sheet breach of upspringing of upspringing, the described outer inserted sheet breach of upspringing is positioned near keyhole insertion end, the described interior inserted sheet breach of upspringing is positioned at away from keyhole insertion end, and the interior inserted sheet breach of upspringing is larger than the 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 the outer inserted sheet breach of upspringing is corresponding, described interior inserted slot and the 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 sliding 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 a 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 being 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 on the key side breach and port, key inserts after plug body, described side breach and the corresponding cooperation of breach on key insertion hole block, described port and the corresponding cooperation of projection on key insertion hole block.

The beneficial effect of the lock core of what the utility model provided prevent technical unlocking 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 a 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, realize key insertion hole block along guide groove activity the upper through hole of the key insertion hole on lock core body and lock core sleeve is blocked and key insertion hole block is set, prevent that the instrument that technical unlocking is used from inserting, concrete implementation procedure is: when after plug body locking, adopt the instrument that technical unlocking is used to insert key insertion hole, and rotational lock core main body, now inserted sheet in lockup state can not be directly rotational lock core main body and opened lock completely, due to the difference of inserted sheet individuality, at least have between an inserted sheet and lock core cover along with rotating the outer inserted sheet that is resisted against the at first lock core cover breach side of upspringing, again by provoking this slice inserted sheet, move it opening, because this inserted sheet and the outer inserted sheet breach side of upspringing leans, can make this inserted sheet remain on opening, and then go to provoke second with the outer inserted sheet inserted sheet that breach side leans of upspringing, make second inserted sheet also move to opening, all move to opening with the outer inserted sheet all inserted sheets that breach matches of upspringing the most at last, thereby crack all inserted sheets that outer inserted sheet is upspring on breach, and lock core body can be rotated, and the interior inserted sheet of the lock core cover breach of upspringing is larger than the outer inserted sheet breach of upspringing, therefore the upspring inserted sheet of gap position of interior inserted sheet now can not be resisted against the upspring side of breach of interior inserted sheet, the inserted sheet that cannot upspring in breach by provoking the interior inserted sheet of lock core cover, reach inserted sheet is resisted against to the upspring side of breach of interior inserted sheet, thereby 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 make the upspring inserted sheet of gap position of interior inserted sheet can be resisted against interior inserted sheet and upspring in the process of side of breach, key insertion hole block guide groove along lock core sleeve under the drive of lock core sleeve moves to closest approach from the solstics of guide groove, key insertion hole block is blocked the upper through hole of the key insertion hole on lock core body and lock core sleeve gradually, in this process, the projection of key insertion hole block and breach are in tandem, in vertical and key direction of insertion, form whole the dead whole key insertion hole of final gear, make instrument that technical unlocking is used cannot insert key insertion hole and remove technical unlocking lock core, finally reach the function that prevents technical unlocking, and the supporting key providing with the utility model is while removing opening lock master, tartar is on the key opened inserted sheet, side breach on the key can be for the breach of key insertion hole block in the time that key insertion hole block blocks key insertion hole, do not affect the rotation of key, same port is on the key also can insert this port for the projection of key insertion hole block, thereby do not affect key turns, therefore, what the utility model provided prevents that the lock core of technical unlocking and supporting key thereof have simple in structure, light, the feature of reliable and good damping effect.

The lock core that prevents technical unlocking the utility model being provided below in conjunction with drawings and Examples and supporting key thereof are further described in detail.
