Description

The key of Multilayered pin tumbler lock and unlatching

Technical field

The present invention relates to cylinder lock set, is the key of a kind of Multilayered pin tumbler lock and unlatching.

Background technology

Cylinder lock is a kind of comparatively common lockset on the market, and it mainly consists of internal cylinder, outer lock core, pellet, spring, and when each internal cylinder pellet is pushed to the interior outer lock core surfaces of revolution, lock core is just unlocked, and principle is comparatively simple.Existing cylinder lock is divided into a letter lock and cross lock, cross lock is compared a letter lock has increased marble hole quantity, thereby has improved to a certain extent unlatching difficulty, but faces the upgrading of existing various technology unlockings, only increase marble hole quantity, the more difficult technical opening of avoiding.

In order to improve the safety of lockset, prior art is as the notice of authorization CN2789374Y of Chinese patent literature publication, June 21 2006 notice of authorization day, utility model name is called " Multilayer antitheft lock barrel ", its primary structure is to comprise lock core, lock ectosome, lock core comprises: internal layer lock core packs in the lock core of middle level, the inner core power transmission shaft of internal layer lock core holds moving axis with the core body of middle level lock core and contacts, middle level lock core packs in lock ectosome, the SMIS power transmission shaft of middle level lock core contacts with the locking kickoff mechanism in lock body and is connected, and SMIS sheath is connected with lock body.This patent documentation is mainly by changing the number of plies of lock core, required opening face when increasing lock core and opening, thus improve unlocking difficulty.But this technology still can adopt the mode of " card pellet " to open, and anti-theft effect is unsatisfactory.

The application for a patent for invention publication number CN1478977A that and for example Chinese patent literature is published, open day on March 3rd, 2004, name is called " a kind of used for spring lock Special-shaped marble ", the structure design of this patent is outside pellet to make a platform, wherein platform is Special-shaped marble head, diameter is less than other pellet, and remainder diameter is less than Special-shaped marble head.When running into technology unlocking, while having outside pellet, Special-shaped marble can not be extruded, when outside pellet is all extruded, lock tube endoporus and lock core choke the special-shaped spring column part of special-shaped list, because its diameter is less, make apertura lateralis and center, locking bolt hole move faulting of slab ends, stop special-shaped list head to enter apertura lateralis, therefore cylinder lock is difficult for by technology release.But above-mentioned pellet, when correct unlatching, also easily causes the situation of pellet screens, to use, brings inconvenience.

The notice of authorization CN23254701Y also publishing just like Chinese patent literature, June 23 1999 notice of authorization day, utility model name is called " theft-proof cylinder lock ", it is mainly between the lock housing of original cylinder lock and lock core, to increase one or more layers theft-proof layer, theft-proof layer is that the opening point marble head of pellet is designed to wedge shape or step with permanent being fixed in lock core or lock housing of pellet.Although this kind of pellet switch can play certain anti-technology unlocking, because it is in fact still two-layer cylinder lock, by existing " hitting spoon " unlocking technique, still can technical opening.

In sum, although existing cylinder lock has the structure that adopts Multilayer lock core, anti-technical opening effect is not good enough.

Summary of the invention

For overcoming above-mentioned deficiency, the object of the invention is to provide to this area the key of a kind of Multilayered pin tumbler lock and unlatching, make it solve existing cylinder lock and easily crack, anti-technical opening ability is comparatively limited to, the technical problem that the mode of unblanking is comparatively single.Its objective is and be achieved through the following technical solutions.

A Multilayered pin tumbler lock, this cylinder lock comprises internal cylinder, outer lock core, internal cylinder, outer lock core are provided with marble hole, filling pellet in marble hole, internal cylinder is provided with keyhole, in outer lock core marble hole, is provided with spring; Internal cylinder is provided with at least two-layer, the internal cylinder of innermost layer of take is first floor internal cylinder, set gradually from inside to outside all the other internal cylinder, the in line number of marble hole that each internal cylinder except first floor internal cylinder is provided with is the integral multiple of first floor internal cylinder, this integral multiple numerical value is identical with each internal cylinder place number of plies numerical value, and it is that marble hole with first floor internal cylinder is arranged as unit that the marble hole of each internal cylinder except first floor internal cylinder is arranged, and the corner difference in each internal cylinder between two adjacent cells is: the in line number of 360 °/outermost layer internal cylinder marble hole; The marble hole of outer lock core is corresponding with outermost internal cylinder marble hole.Adopt said structure, multilayer internal cylinder is successively unlatching when carrying out open operation, and front one deck internal cylinder turns over above-mentioned corner value after opening, turn over 360 ° except after the angle of the in line number of outermost layer internal cylinder marble hole, to drive later layer internal cylinder to rotate in the lump, realize the unlatching of lower one deck internal cylinder.For example, after first floor internal cylinder is opened, turn over certain angle, first floor internal cylinder and the release of second layer internal cylinder, next drive second layer internal cylinder to rotate in the lump by first floor internal cylinder, rotate after above-mentioned equal angular, the 3rd layer of internal cylinder release, then drives the 3rd layer of internal cylinder to rotate in the lump by first floor internal cylinder, second layer internal cylinder, analogizes in proper order, finally realize the release of outermost layer internal cylinder, by outermost layer internal cylinder and outer lock core, relatively rotate the unlatching that realizes lockset.The lock core of this kind of structure, can not adopt general key to open, because pellet need to or shrink for several times by jack-up in the mutual opening process between each internal cylinder, and normal key is when open again, can only carry out jack-up one time, obviously cannot meet the demands.Same, when pellet resets, its pellet also needs repeatedly to push up back or recovery operation, and general key also cannot repeatedly push up back or recovery operation.This is also the difference of this Multilayered pin tumbler lock and existing cylinder lock maximum, opens this kind of Multilayered pin tumbler lock, must need the key that has can repeatedly change pellet position.And according to existing technology unlocking, because of multilayer internal cylinder of the present invention, not only marble amount is many, and need to carry out repeatedly upspringing or shrinkage operation of pellet, enable to open first floor internal cylinder, but from second layer internal cylinder, due to pellet jack-up or contraction are had to further requirement, therefore difficulty is larger; If adopt revotating card list by force, between two adjacent internal cylinder, easily dally, no matter rotation is several times, still cannot open.

In the inner and/or outer lock core of described internal cylinder, be provided with cover plate mechanism for auto, cover plate mechanism for auto consists of cover plate, little spring, in the inner and/or outer lock core of described internal cylinder, be provided with the cover plate chute intersecting vertically with an in line marble hole, cover plate and little spring offset and are placed in cover plate chute, described cover plate is provided with position-limited marble hole, position-limited marble hole be one end to the gradually little hole of the other end, the pellet of the corresponding in line marble hole of described cover plate chute during to opening face, is had extruding between pellet and described position-limited marble hole by jack-up.In existing skill unlocking technique, a kind of mode often adopting is: to the whole jack-up of all pellets, to extreme higher position, recycling pellet falls after rise and pellet is stuck in to opening face.Adopt the object of cover plate, prevent that pellet from being upspring too high, when pellet is upspring to opening face, pellet and cover plate offset, under little spring effect, cover plate, pellet play pendulum, and namely so-called pellet cannot " be stood firm " at opening face, therefore pellet is stuck in the probability of opening face, greatly reduce, can effectively prevent technology unlocking.

In conjunction with above-mentioned, take that to adopt two-layer internal cylinder and adopt three layers of internal cylinder be example as preferred two schemes.Internal cylinder is two-layer scheme: described internal cylinder is provided with two-layer, first floor internal cylinder is provided with the in line marble hole of four rows that is cross distribution, second layer internal cylinder is provided with the in line marble hole of eight rows, and described outer lock core is provided with the eight row in line marble hole corresponding with second layer internal cylinder; It is an arrangement units that four of the first floor of take is arranged in line marble hole, the arrangement of described second layer internal cylinder consists of two described arrangement units, and the corner difference of these two arrangement units is: the in line number of 360 °/second layer internal cylinder marble hole, corner difference is 45 °.In this scheme, when key operated first floor internal cylinder, be the pellet of the in line marble hole of four rows of first floor internal cylinder, and second layer internal cylinder four pellets of arranging in line marble hole corresponding with first floor internal cylinder are open position by jack-up, now rotate first floor internal cylinder; When turning over angle and be 45 °, the in line marble hole of four rows of first floor internal cylinder is arranged in line marble hole with other four of second layer internal cylinder and is alignd, and now needs pellet to carry out secondary while having upspring to second layer internal cylinder open position, can open second layer internal cylinder.After its difficult point one is that first floor internal cylinder is opened, it can rotate relatively with second layer internal cylinder, cannot adopt the mode of revotating card list by force to rotate internal cylinder, and internal cylinder rotational angle is had to strict restriction; Secondly, second layer internal cylinder need to again crack pellet when opening, and increases unlocking difficulty.

Internal cylinder is the scheme of three layers: described internal cylinder is provided with three layers, first floor internal cylinder is provided with the in line marble hole of four rows that is cross distribution, second layer internal cylinder is provided with the in line marble hole of eight rows, the 3rd layer of internal cylinder is provided with the in line marble hole of 12 row, and described outer lock core is provided with and the 3rd layer of in line marble hole of 12 row that internal cylinder is corresponding; It is an arrangement units that four of the first floor of take is arranged in line marble hole, the arrangement of described second layer internal cylinder consists of two described arrangement units, and the corner difference of these two arrangement units is: 360 °/the 3rd layer in line number of internal cylinder marble hole, and corner difference is 30 °; The arrangement of described the 3rd layer of internal cylinder consists of three described arrangement units, and in these three arrangement units, the corner difference of two adjacent arrangement units is: 360 °/the 3rd layer in line number of internal cylinder marble hole, corner difference is 30 °.Its principle and internal cylinder are that two-layer scheme is identical, increase the difficulty that its skill of the number of plies of internal cylinder unblanks and also increase accordingly.

Similar with above-mentioned cover plate mechanism for auto, also has a kind of baffle mechanism, its structure is that described first floor internal cylinder is provided with baffle mechanism, baffle mechanism is by baffle plate, little spring forms, in first floor internal cylinder, be provided with the baffle chute intersecting vertically with in line marble hole, baffle plate and little spring offset and are placed in baffle chute, described baffle plate is provided with guiding marble hole, when the keyhole of described first floor internal cylinder does not insert key, the pellet of described first floor internal cylinder marble hole is barred from first floor internal cylinder marble hole and is not exposed by described baffle plate, when the keyhole of described first floor internal cylinder inserts key, described first floor internal cylinder marble hole aligns with described guiding marble hole, pellet is exposed to described baffle plate.This baffle mechanism is with respect to the difference of cover plate mechanism for auto, and it is arranged at first floor internal cylinder, and main purpose is when keyhole inserts key, all pellets of first floor internal cylinder not to be intercepted in the marble hole of first floor internal cylinder and do not exposed; When inserting key, by key, baffle plate is backed down, thereby pellet is exposed to baffle plate, can carry out unlock operation.Such structure, mainly to have increased the complexity that skill is unblanked, carrying out skill while unblanking, need to first baffle plate be backed down and keep, slightly loosening, will have influence on the state of all pellets, if such Si road baffle mechanism is set in cross lock core, operation easier is very big so, therefore theftproof performance is good.

Described outer lock core is provided with to report to the police and inspires device, it is by two wires are installed at least one marble hole of described outer lock core that this warning inspires device, mutually insulated under the end of a thread original state of these two wires, and the end of a thread position is set to higher than outer lock core pellet opening face.This kind report to the police to inspire device, is mainly by when cylinder lock is unblanked, and must need each pellet of lock core to push up to opening face and can open.Therefore a kind of whether structure of overhead opening face of lock core marble that judges is set, two wires with the end of a thread described in, when pellet jack-up surpasses opening face, the end of a thread of pellet top and two wires offsets, because pellet is originally as conducting metal, therefore two wire line conductings, the warning circuit conducting that these two wires connect, realizes and reporting to the police.This structure is mainly that key is identified, once inserting error key reports to the police, can effectively play antitheft object.This is reported to the police and inspires device except adopting said structure, also can adopt following structure: reporting to the police and inspiring device is by a wire is installed at least one marble hole of described outer lock core, under the end of a thread original state of this wire, insulate with outer lock core, and the end of a thread position is set to higher than outer lock core pellet opening face; Outer lock core connects another wire.The operating principle of this structure and effect are identical with the former, are mainly that the mode of connection of wire is different.

Aforementioned content has been told about a kind of Multilayered pin tumbler lock, and this kind of Multilayered pin tumbler lock need to be by a kind of key that can repeatedly change pellet position, this key comprises key piece, handle, key piece is provided with bullet groove, its structural feature is to be provided with in described handle the governor motion that can change described key piece jack-up pellet height, governor motion comprises a stair-stepping adjusting rod, and adjusting rod connection pushes away handle, pushes away handle slip and is placed in the chute of described handle outer wall; Described handle one end is flexibly connected with described key piece, and the pole face of described adjusting rod and described key piece offset.Because key piece is for being movably placed in handle end, utilize the ladder section of adjusting rod and the relation that key piece bottom alternately offsets, when key piece and adjusting rod offset position while being transferred to another ladder section by a ladder section, ladder section has the effect of promotion to key piece, realizing the height of key piece in keyhole regulates, finally pellet is carried out repeatedly to jack-up or shrinkage operation, complete and unblank or locking process.
