Lock body commutation method and component and its lock body for lock body commutation

Technical field

The present invention relates to electronic lock, the more particularly to electric control lock in electronic lock, the lock body can not only commutate And can inside and outside handle（Also referred to as door handle）Do not link, so as to when performing door opening action, not have to overcome opposite door The resistance of handle gravity in itself and the linking spring on handle over there, so as to make door opening action lighter, good hand touch.

Background technology

For traditional mechanical lock, the function of inside and outside handle is basically identical so that the problem of needing commutation with regard to being not present； And electronic lock body is because the door opening function of its inside and outside handle is different, such as outer handle needs could when clutch is in conjunction state Open the door, otherwise counter can only put on lock and can not open the door, and interior handle all should can open the door and lock under any state, be this Commutation problem is there is in the door leaf that same lock body is opened to for difference.For having spring lock reverse flow technique, at present By various schemes, wherein than more typical technical scheme such as Application No. 201520897227.0, it is entitled " readily removable The patent of dress electronic lock operation drive component ", discloses outer barrel, and the cavity on outer barrel with both ends open, the outer barrel is provided with The slideway of one connection cavity；Actively it is connected to the pin of slideway；The spring being installed between pin and outer barrel, the spring are used for One elastic force that pin is pushed away to chamber is provided；First inner cylinder, first inner cylinder is installed in rotation in outer barrel, in first The shifting block radially protruded outward is provided with the lateral wall of cylinder, the both ends of the outer barrel, which offer, to be circumferentially extended along it and supply to dial The breach of block insertion, the outside of first inner cylinder are provided with the recess of supply and marketing nail insertion；Second inner cylinder, second inner tube installation In in outer barrel, and the axial arranging of the first inner cylinder, the second inner cylinder along outer barrel；Projection is provided with the outside of second inner cylinder, should The both ends of outer barrel are provided with for raised embedded groove.The program by it is various dial-out or rejection square tongue, latch bolt dial handles On the outer barrel of concentration, allow the first inner cylinder and the second inner cylinder can the inside and outside exchange on the outer barrel, but in the program can not allow Outer handle does not link.

Secondly, Application No. 201310143199.9, the patent of entitled " a kind of electronic anti-theft lock ", one kind is disclosed Close the door and locked with latch bolt, can use and outer handle while solve inclined tongue of lock, square tongue and slow-witted tongue, and only need to change seldom part and just can make Lock body is opened on a left side and the right side open between be interchangeable electronic lock body.It include housing, latch bolt device, square tongue device, slow-witted tongue device with And the Internal handle shifting block being connected with Internal handle, reverse portion provided with Internal handle latch bolt on Internal handle shifting block, Internal handle square tongue reverses Portion and Internal handle square tongue dial-out portion, it is characterized in that also including the outer handle driving link being connected with outer handle, it which is provided with outer handle Square tongue dial-out portion, shaft and the pin hole being arranged on shaft；Outer handle Passive part, it which is provided with outer handle latch bolt and reverse Portion, outer handle square tongue reverse portion, the slow-witted tongue of outer handle reverses portion, axle hole and its pin member can stretch into axis hole when being promoted Resilient pin device inside portion, back-moving spring is provided between outer handle Passive part and housing；Electrical retractor, stretched at it Contracting action part be provided with one be used for promote the resilient pin device pin member promotion face, outer handle driving link and Internal handle shifting block is separately mounted to the both sides of outer handle Passive part, and shaft is arranged in axle hole, and outer handle driving link can phase External handle Passive part rotates, and Internal handle shifting block can rotate relative to outer handle Passive part, the pivot center of Internal handle shifting block, rotating shaft The axis in portion, the axis of axle hole are conllinear.

The technology contents of Application No. 201310143199.9 are analyzed, its described Internal handle shifting block is provided with Internal handle latch bolt Portion is reversed, the needs used must be overturn in order to meet to commutate, the Internal handle latch bolt must just be reversed to portion etc. and dial handle sheet Body is arranged to symmetry, and the Internal handle latch bolt portion of reversing must be allowed to follow the Internal handle shifting block to exchange movement, so All the time there is one on the Internal handle shifting block and unnecessary dial handle and space-consuming（Such as the patent accompanying drawing 2 or shown in Fig. 9 with Another the symmetrically arranged wiper arm of part 74）, also increase the difficulty that commutation is changed；If the latch bolt portion of reversing is positioned at design Axis on, then the terminal end shape that the latch bolt reverses portion must be straight（Portion as shown in the patent accompanying drawing 2 or Fig. 9 Part 71）Otherwise left-right reversed use is unable to, but straight terminal end shape is unfavorable for withdrawing latch bolt, conventional use of shape is most It is the arciform of slight curvature well；Secondly it also is provided with outer handle latch bolt on the outer handle Passive part in the patent and reverses portion 91, It is this described outer handle because the outer handle Passive part is arranged between the Internal handle shifting block and the outer handle driving link Passive part is normally at the median plane position of lock body（The median plane refers to the median plane between lock body two side）Near zone, And the control body of rod of latch bolt tail end also is located at lock body median plane position, causing outer handle latch bolt to reverse portion 91 needs turning to avoid （Part 91 as shown in the patent accompanying drawing 2 is the shape of deflection）The tail end body of rod of its latch bolt 2 can just snap into latch bolt by So as to the big space occupied mostly in lock body on moving part 21, moreover the outer handle latch bolt reverses portion 91 and is arranged on the outer grip On hand Passive part, the space for being considered as prime locations around the outer handle Passive part can be also taken.

Due to the very more such as clutches of part, various instigation parts, driving member, square tongue, latch bolt and its control in electronic lock body Part processed etc. is very limited for the space that this can be utilized, and the space near lock body median plane position is commonly called as gold Section, the position of any one part relevant with clutch reversing, the change of shape, is likely to directly result in other biographies in lock body Move the significantly adjustment of structure and change and form the product of a new construction；It is passive including the outer handle how to simplify for this The structure of part including part, the Internal handle shifting block is so as to be not only convenient for changing commutation, and and can does not have to take excessively Space, it is to need constantly to design improved emphasis.

The content of the invention

In view of the shortcomings of the prior art, the present invention proposes a kind of new lock body commutation method and its structure.

First, the present invention proposes a kind of Novel lock body commutation method, sets middle clutch block, can be connected the outer of outer handle Handle contiguous block and the interior handle contiguous block that can be connected interior handle, the outer handle contiguous block and interior handle contiguous block are split The axial both ends of the middle clutch block simultaneously can be respectively relative to the middle clutch block rotation, be set on the middle clutch block The on-of pin that can be moved is equipped with, the combination recess that can receive the on-of pin is provided with the outer handle contiguous block, when When the on-of pin is inserted into the combination recess, it can join between the middle clutch block and the outer handle contiguous block It is dynamic, otherwise it can only relatively rotate；It is characterized in that：

The interior handle contiguous block is configured to exchange in first used handle contiguous block in handle contiguous block or second； Allow the middle clutch block, handle contiguous block is combined as the first module in outer handle contiguous block and first, allow the middle clutch Handle contiguous block is combined as the second module in block, outer handle contiguous block and second；

The latch bolt for being not provided with stirring latch bolt in lock body on first module, the second module dials handle, first module, second It is separately provided for stirring group handle that tongue instigation was instigateeed and stayed to square tongue on module；

It is provided with the middle clutch block and dials handle and for stirring slow-witted tongue instigation for stirring the first centre of square tongue instigation Handle is dialled among second, is additionally provided with the outer handle contiguous block and dials handle for stirring the outer handle of square tongue instigation, it is described outer to hold Hand dials handle in itself along its axisymmetrical；

It is provided with described first on handle contiguous block and dials handle for stirring the first square tongue of square tongue instigation, stirs what slow-witted tongue was instigateeed First slow-witted tongue dials handle and the first inner shaft for being attached on the middle clutch block, and first square tongue, which dials handle, to be included Handle is dialled after handle and first is dialled before first；The second square tongue for stirring square tongue instigation is provided with described second on handle contiguous block Dial handle, stir the second slow-witted tongue group handle and the second inner shaft for being attached on the middle clutch block that slow-witted tongue is instigateeed, Second square tongue is dialled and dials handle after group handle and second before handle includes second；Described first inner shaft is inner with described second The relatively front and rear closing of shaft together when, first square tongue dials handle and second square tongue and dials handle correspondence, described the One slow-witted tongue dials handle and the second slow-witted tongue dials handle also correspondence；When being configured to first module, handle connects in described first Group handle, which corresponds to, before the first of block dials handle among the first of the middle clutch block, in described first after the first of handle contiguous block Dial the outer handle that handle corresponds on the outer handle contiguous block and dial handle, the slow-witted tongue of the first of handle contiguous block dials handle pair in described first Handle is dialled among described in Ying Yu among the second of clutch block；When being configured to second module, handle contiguous block in described second Second before dial handle and correspond to handle is dialled among the first of the middle clutch block, dialled after the second of handle contiguous block in described second The outer handle that handle corresponds on the outer handle contiguous block dials handle, and it is corresponding to dial handle for the slow-witted tongue of the second of handle contiguous block in described second Handle is dialled among the second of the middle clutch block；

When arranging the lock body in the first enabling direction, using the first module, the outer handle contiguous block of lock body is configured in institute State the axial left end of middle clutch block, right-hand member of the handle contiguous block configuration in the middle clutch block in described first；

When exchanging the direction of lock body and arranging the lock body in second enabling direction, using the second module, without switch the centre from The direction of block is closed, but the outer handle contiguous block is transposed to the right-hand member of the middle clutch block, by handle in described second Contiguous block configures the left end in the middle clutch block.

Wherein, first module, the latch bolt for being not provided with stirring latch bolt in lock body on the second module dial handle, main meaning It is that will dial handle with the latch bolt for stirring latch bolt function in lock body to be not arranged in first module, on the second module, but individually Configuration is not precluded from having interaction relation between them in lock body.

Wherein, the interior handle contiguous block is configured to exchange in first used handle in handle contiguous block and second Contiguous block, it is handle contiguous block in handle contiguous block or second in first to define the interior handle contiguous block, but described first In interior handle contiguous block and second handle contiguous block be will not two parts used at the same time but the scheme of a preparation and a use, work as lock When handle contiguous block in described first is assembled with body, handle contiguous block is as just commutation spare part to dealer in described second Or user provides, vice versa.

Wherein, during by the described first inner shaft together with the relatively front and rear closing of the described second inner shaft, institute State the first square tongue group handle and second square tongue group handle correspondence, the first slow-witted tongue group handle and the second slow-witted tongue group handle are also front and rear Correspond to, first " the first inner shaft is together with the relatively front and rear closing of the described second inner shaft " feature, not It is to say to need that there is relative closing between the first inner shaft described in lock body use and the second inner shaft Annexation, but first square tongue is dialled between handle and second square tongue group handle, the first slow-witted tongue dials handle in order to compare The use of relative position between handle, structural relation and the comparison method used temporarily, this method and product is dialled the second slow-witted tongue Mode is unrelated, and this feature main definitions first square tongue dials handle and second square tongue is dialled between handle, the first slow-witted tongue Dial handle and the second slow-witted tongue dials the condition with corresponding relation between handle；Secondly, " first square tongue dials handle and second square tongue Dial handle correspondence, the first slow-witted tongue dials handle and the second slow-witted tongue group handle also correspondence " feature, main definitions described first Between square tongue group handle and second square tongue group handle, between the first slow-witted tongue group handle and the second slow-witted tongue group handle, respectively described Handle contiguous block in first, the placement position in described second on handle contiguous block, angle etc. are basically identical, when will described in In first in handle contiguous block or described second handle contiguous block be arranged on the middle clutch block be configured to the first module or During the second module, first square tongue dials handle or second square tongue dials handle, the first slow-witted tongue dials handle or the second slow-witted tongue dials handle Connection can be formed with the various instigation parts in essentially identical posture, position and lock body, both not have to picture so The structure that its described interior handle shifting block and its group handle are arranged to have symmetry in itself by 201310143199.9 prior arts, Although be primarily not allow in described first can have between handle contiguous block in handle contiguous block or described second symmetry but It is not necessary to having symmetry, can be set in itself so as to which first square tongue dials group handle on handle or second square tongue group handle It is set to shape, shape or head shape with hook of deflection of various bendings etc..Configuring first module or the second module When, it is foregoing it is described dial handle with corresponding relation, be also primarily referred to as they function, shape or and instigateeing between part Relative position relation etc. is essentially identical.Because the various groups of outside passing powers of handle are mainly the power of direction of rotation, handle sheet is dialled When body is arranged to the shape of various bendings, the shape of deflection or head shape with hook, can greatly improve power transmission and With reference to stability and reliability.

Wherein, the outer handle dials handle in itself along its axisymmetrical, refers mainly to what is stretched out on the outer handle contiguous block Outer handle dials handle in itself along the extension axisymmetrical of its group of handle, so as to allow the outer handle contiguous block can be in the first module or the It is general in two modules, it can be used in the both ends of middle clutch block difference reversing of position.

According to such scheme, be compared with the prior art its it is beneficial have technical effect that, allow first square tongue dial handle with Second square tongue dials handle, the first slow-witted tongue is dialled handle and is correspondingly arranged with the second slow-witted tongue group handle, from regardless of whether using described first Handle contiguous block in interior handle contiguous block or described second, can allow first square tongue dial handle and second square tongue dial handle, Described first slow-witted tongue dials handle and the second slow-witted tongue dials handle and has essentially identical placement position, angle etc., but does not require to dial handle in itself It is symmetrical shape；Secondly, allow in described first handle contiguous block can be exchanged mutually in handle contiguous block or described second, from And only need more to replace a part when changing the direction of lock body；In addition, first square tongue dials handle and described second Square tongue dials handle, the first slow-witted tongue is dialled handle and is correspondingly arranged with the second slow-witted tongue group handle, so as in the middle clutch block, described It can not have to set group handle for reversing latch bolt on handle contiguous block in handle contiguous block or described second in first, simplify described Middle clutch block, in described first in handle contiguous block or described second handle contiguous block structure.The above method is not only with non- Often simple method, structure preferably solve the problems, such as commutation and realize the function that inside and outside handle does not link simultaneously.

Further technical scheme is also possible that can rotationally be riveted to the interior handle by the outer handle contiguous block On contiguous block, wherein：

The outer handle contiguous block of lock body is configured into the axial left end in the middle clutch block, handle connects in described first Block configures the right-hand member in the middle clutch block, and the outer handle contiguous block can rotationally be riveted to handle in described first and connect Connect on block, so as to allow the outer handle contiguous block, handle contiguous block is configured to one in the middle clutch block and described first The first overall module；

The outer handle contiguous block of lock body is configured into the axial right-hand member in the middle clutch block, handle connects in described second Block configures the left end in the middle clutch block, and the outer handle contiguous block can rotationally be riveted to handle in described second and connect Connect on block, so as to allow the outer handle contiguous block, handle contiguous block is configured to one in the middle clutch block and described second The second overall module.

Further technical scheme is also possible that to be configured to exchange outside first used by the outer handle contiguous block Handle contiguous block or the second outer handle contiguous block, it is additionally provided with the first outer handle contiguous block for stirring square tongue instigation First outer handle dials handle, is additionally provided with the second outer handle contiguous block and is dialled for stirring the second outer handle of square tongue instigation Handle, specular is arranged between the first outer handle contiguous block and the second outer handle contiguous block, but is held outside described first Hand dials handle or the second outer handle dials handle in itself and asymmetry；Allow the middle clutch block, the first outer handle contiguous block and Handle contiguous block is combined as the first module in one, allow the middle clutch block, handle connects in the second outer handle contiguous block and second Connect block and be combined as the second module.

Because the described first outer handle group handle or the second outer handle group handle are asymmetric in itself, outside actually described first Handle dials handle or the second outer handle dials handle and has the asymmetrical shape such as deflection, bending in one direction in itself, so as to Allow the described first outer handle to dial handle or the second outer handle is dialled handle and is incorporated in itself in the lock body of different driving structure and for example stretches Go out in the different square tongue lock body of length.In in general lock body structure, square tongue, which is stretched out, typically uses one-level（Disposably）Stretching side Case is shorter so as to extension elongation, in the two level stretching of stretching fond of gossip or three-level stretching scheme is realized, for driving square tongue to choose It is also rotary motion that the dynamic outer handle of switch, which dials handle, between the handle part of two rotary motions（Different from two circles Part between）Bigger change occurs between different rotary angle positions its faying face, needs to set not for this Faying face with angle realizes multistage transfer to.

Even so, handle is dialled in lock body with identical in order to allow the described first outer handle to dial handle or the second outer handle Direction and driving direction, namely all there is identical direction and driving direction in the both sides of the middle clutch block, described Specular is arranged as between one outer handle contiguous block and the second outer handle contiguous block, so can be square in lock body commutation Just the first module or the second module are used, the first module or the second module of this structure not only go for two level, three In the lock body of level driving, it can be applicable in the lock body of one-level driving.

Further technical scheme is also possible that the upper and lower latch bolt for also including reversing latch bolt dials handle；

The first module is used when arranging the lock body in the first enabling direction, the upper latch bolt is dialled handle configuration and connected in the outer handle On block but the upper latch bolt is dialled and not linked between handle and the outer handle contiguous block, the middle clutch block, and described oblique Tongue dials handle configuration in described first on handle contiguous block, and the lower latch bolt dial in handle and described first handle contiguous block with And formed between the middle clutch block and radially linked respectively, now,

When the on-of pin be not inserted into the combination recess allow the middle clutch block and the outer handle contiguous block it Between do not formed when radially linking, when rotating outer handle and driving the outer handle contiguous block rotation, the outer handle contiguous block phase Handle and the middle clutch block idle running are dialled for the upper latch bolt, can not only latch bolt be withdrawn nor square tongue but energy can be withdrawn Square tongue is transferred to lock；

Shape between the middle clutch block and the outer handle contiguous block is allowed when the on-of pin is inserted into the combination recess When radially linking, the middle clutch block also concomitant rotation when rotating outer handle and driving the outer handle contiguous block rotation, But in described first handle contiguous block and the interior handle that is connected will not concomitant rotation, the outer handle contiguous block of linkage and The middle clutch block, which can not only withdraw square tongue, which unlocks, can also transfer to square tongue to lock, and the middle clutch block rotated is also The lower latch bolt can be driven to dial handle to rotate on handle contiguous block in described first and then withdrawn by means of the lower latch bolt group handle Latch bolt；

Handle in rotation and when driving in described first the handle contiguous block to rotate, handle contiguous block is relative to described in described first Middle clutch block idle running, but can not withdrawn only by means of first square tongue group handle during handle contiguous block in rotation described first Square tongue unlocks, transfers to square tongue to lock and dial handle withdrawal latch bolt also by way of the lower latch bolt；

The second module is used during the lock body for exchanging direction second of enabling direction of arrangement of lock body, the upper latch bolt is dialled handle configuration and existed In described second on handle contiguous block and with described second in handle contiguous block formed radially linkage but with the middle clutch block Between do not link, and the lower latch bolt dials handle configuration on the outer handle contiguous block, the lower latch bolt dial handle with it is described outer Not linkage but the formation radially linkage between the middle clutch block between handle contiguous block, now,

When the on-of pin be not inserted into the combination recess allow the middle clutch block and the outer handle contiguous block it Between do not formed when radially linking, when rotating outer handle and driving the outer handle contiguous block rotation, the outer handle contiguous block phase Handle and the middle clutch block idle running are dialled for the lower latch bolt, can not only latch bolt be withdrawn nor square tongue but energy can be withdrawn Square tongue is transferred to lock；

Shape between the middle clutch block and the outer handle contiguous block is allowed when the on-of pin is inserted into the combination recess When radially linking, the middle clutch block also concomitant rotation when rotating outer handle and driving the outer handle contiguous block rotation, But in described second handle contiguous block and the interior handle that is connected will not concomitant rotation, the outer handle contiguous block of linkage and The middle clutch block, which can not only withdraw square tongue, which unlocks, can also transfer to square tongue to lock, and the middle clutch block rotated is also The lower latch bolt can be driven to dial handle to rotate and then withdraw latch bolt by the lower latch bolt group handle；

Handle in rotation and when driving in described second the handle contiguous block to rotate, handle contiguous block is relative to described in described second Middle clutch block idle running, but can not only dial handle by means of second square tongue during handle contiguous block in rotation described second and withdraw Square tongue unlocks, transfers to square tongue to lock and dial handle withdrawal latch bolt also by way of the upper latch bolt.

According to above-mentioned technical proposal, arrange that upper and lower latch bolt dials handle, and allow the upper and lower latch bolt to dial handle in different configurations In play a part of withdraw latch bolt, allow withdraw latch bolt functional independence connect in handle in the outer handle contiguous block, described first Connect handle contiguous block in block or described second, and by the upper and lower latch bolt dial handle split in the first module or the second module two End, it can not only so allow the upper and lower latch bolt to dial handle and be directly protruding into from the position close to lock housing body to latch bolt End-Management bar Both sides up and down and avoid the Golden area distinction near lock body median plane, and the outer handle contiguous block, institute can be greatly simplified State in first the structure of handle contiguous block in itself in handle contiguous block or described second.
