本申请提供一种锁具，图1所示为锁具100的一具体实施例，其包括锁壳10、设置于锁壳10中的锁芯组件30以及与锁芯组件30传动连接的反锁组件50。
本申请还提供一种锁合装置，图2-3所示为该锁合装置200的一具体实施例，包括第一物体210、第二物体220以及锁具100。其中，锁具100安装于第一物体210上，与第二物体220相作用使得两个物体210、220可以锁合在一起或者可以分开。具体地，锁具100具有开锁状态和锁定状态，在锁定状态下，如图3所示，安装有该锁具100的第一物体210与第二物体220锁合。如，将锁具100安装至门/窗时，可以将门/窗锁定至门框/窗框，形成私密的空间。又如，将锁具100安装至柜门时，可以将柜门锁定至柜体，形成安全的空间存放贵重物品、机密文件等。在未锁定状态下，如图2所示，安装有锁具100的第一物体210可以相对于第二物体220打开，如可以打开门窗透气，打开抽屉取放文件等。
请同时参阅图4-6，所述锁芯组件30作为锁具100的基本部分，可与一钥匙（图未示）配合实现锁具100的锁定和开锁。在本实施例中，锁芯组件30包括锁胆32、锁尺单元34以及锁定件36。具体地，锁胆32整体上为圆柱状结构，可转动地设置于锁壳10中。锁胆32的中央设置锁孔321，用于***与之相匹配的钥匙。在将钥匙***至锁孔321之后，用力旋转钥匙可以带动锁胆32旋转。锁尺单元34设置于锁胆32的轴向内侧端，在锁胆32的驱动下带动锁定件36转动至一锁定位置或一未锁定位置，进而驱动与之连接的锁体、锁舌等伸缩移动，实现锁具100的锁定和开锁。锁定件36可以是单独成型后连接至锁尺单元34，也可以与锁尺单元34是一体结构。图示实施例中，锁定件36为锁钩结构。根据锁定件36的锁钩结构的不同朝向，锁定件36在进行锁定操作时可以有不同的旋转方向。
请同时参阅图7，锁胆32和锁尺单元34之间设有第一离合机构40，第一离合机构40包括相互作用的第一驱动部42和第一离合部44。本实施例中，第一驱动部42设置于锁胆32面向锁尺单元34的侧端，第一离合部44设置于锁尺单元34面向锁胆32的侧端。第一驱动部42包括相对的第一驱动面C1和第二驱动面D1；第一离合部44形成弧形槽441，第一离合部44于弧形槽441的周向两侧分别形成第一离合面C2和第二离合面D2。优选地，第一驱动部42为驱动销，伸入至第一离合部44的弧形槽441中，其第一驱动面C1对应第一离合面C2、第二驱动面D1对应第二离合面D2。第一驱动部42可以相对于第一离合部44在弧形槽441中转动，使得其第一驱动面C1与第一离合面C2相抵接或者相分离、第二驱动面D1与第二离合面D2相抵接或者相分离。
第一驱动部42的第一驱动面C1与第一离合面C2相抵接时，第一离合机构40处于第一接合状态，锁胆32可以驱使锁尺单元34沿第一方向（如逆时针方向）转动；第二驱动面D1与第二离合面D2相抵接时，第一离合机构40处于第二接合状态，锁胆32可以驱使锁尺单元34沿第二方向（如顺时针方向）转动。第一驱动面C1与第一离合面C2分离、第二驱动面D1与第二离合面D2分离时，第一离合机构40处于分离状态，锁胆32转动时锁尺单元34保持不动，即锁胆32空转。优选地，第一离合面C2、第二离合面D2之间的间隔（即弧形槽441）所对应的圆心角大约为180度。本申请在锁胆32和锁尺单元34之间设置第一离合机构40，使得锁胆32和锁尺单元34具有分离和接合两种状态。只有在接合状态下，锁胆32能够驱使锁尺单元34转动，进行锁定或者开锁。
在一些实施例中，第一驱动部42可以是单独成型后组装至锁胆32上，也可以是与锁胆32一体成型；第一离合部44可以是单独成型后组装至锁尺单元34上，也可以是与锁尺单元34一体成型。
请同时参阅图8，所述反锁组件50用于锁具100的无钥匙锁定，即在锁胆32不***钥匙的情况下实现锁具100的锁定。反锁组件50包括操作件52和复位件54，操作件52可以是旋钮等，复位件54可以是螺旋弹簧、扭簧等。
操作件52与锁尺单元34之间设有第二离合机构60，第二离合机构60包括相互作用的第二驱动部62和第二离合部64，其中第二驱动部62与反锁组件50连接、第二离合部64与锁尺单元34连接。通过第二离合机构60，使得反锁组件50和锁尺单元34具有分离和接合两种状态。在接合状态下，通过操作件52的转动可以驱使锁尺单元34、锁定件36转动进行锁定。如此，本申请的锁具100在使用时，既可以通过钥匙带动锁胆32和锁尺单元34、锁定件36转动实现锁定，也可以通过操作件52带动锁尺单元34、锁定件36转动实现锁定，既实现了无钥匙介入的锁定，增加了操作的便利性。
第二驱动部62为弧形块，其周向两侧分别形成第三驱动面A1、第四驱动面B1；第二离合部64同样为弧形块状，其周向两侧分别形成第三离合面A2、第四离合面B2。第二驱动部62和第二离合部64同轴设置且尺寸相当，也就是两者处于同一圆环上。第三驱动面A1和第三离合面A2彼此相对；第四驱动面B1和第四离合面B2彼此相对。操作件52在旋转时，可使得第三驱动面A1与第三离合面A2相抵接或者相分离，或者使得第四驱动面B1与第四离合面B2相抵接或者相分离。优选地，第二驱动部62、第二离合部64的周向长度所对应的圆心角均约为90度。
复位件54的一端连接在操作件52上、另一端连接在一固定件，如锁壳10上。操作件52在外力的作用下相对于锁壳10转动时，使得复位件54被压缩或者被拉伸；当作用于操作件52上的外力撤销时，复位件54恢复形变而推动操作件52反向转动复位。优选地，操作件52和锁壳10上分别设置一定位部59，两个定位部59与复位件54的两端相抵接或者相插接。操作件52相对于锁壳10旋转时，复位件54与操作件52相抵顶的一端随着锁壳10的转动而转动，进而产生变形，形成使操作件52反向复位的复位弹力。
锁胆32安装于操作件52中，两者优选地摩擦配合，使得锁胆32在不受外力作用时可以固定在操作件52中随之同步转动、在受到外力作用（如扭转钥匙）时可以相对于锁胆32转动。优选地，操作件52的内部中央设置有安装锁胆32的锁管56，操作件52的外端面在对应锁管56的位置设有穿孔529，使得锁胆32的锁孔321能够外露。可以在锁胆32和/或锁管56上设置可滑动的锁定销，使得锁定销的长短排列与钥匙的齿形相对应，通过***钥匙使得锁定销滑动解锁，令锁胆32可以相对于锁管56转动。
以下以逆时针方向转动锁定、顺时针方向转动开锁为例对本申请锁具100的运行过程进行说明：
在一实施例中，如图9所示，初始时，锁具100处于开锁状态，第一离合机构40处于接合状态，第二离合机构60处于接合状态。具体地，第一驱动部42的第一驱动面C1与第一离合部44的第一离合面C2抵接；第二驱动面D1远离第二离合面D2，两者之间的间隔所对应的圆心角大约为180度，也就是半个圆。第二驱动部62的第三驱动面A1与第二离合部64的第三离合面A2相抵接，第四驱动面B1与第四离合面B2分隔开且两者之间的间隔对应的圆心角大约为180度，也就是半个圆。
在未锁定状态下转动操作件52进行锁定时，如图9a所示，施加作用力将操作件52逆时针方向旋转一定角度（如90度），操作件52内的锁胆32随着操作件52同步转动。由于第二离合机构60的第三驱动面A1、第三离合面A2相抵接，操作件52的转动将推动锁尺单元34、锁定件36随之逆时针方向转动相应的角度，到达锁定位置。此时，锁定件36与第二物体220锁合，锁具100处于锁定状态。在此过程中，操作件52、锁胆32、锁尺单元34、锁定件36同步转动，第一离合机构40、第二离合机构60均保持在接合状态不变。但是，由于操作件52的转动，复位件54被压缩或拉伸而产生弹性变形。
通过操作件52将锁具100锁定之后，松开操作件52，如图9b所示，复位件54恢复形变而推动操作件52反向（即顺时针方向）转动复位，使得第三驱动面A1与第三离合面A2分离，第二离合机构60切换至分离状态。此时，第三驱动面A1、第三离合面A2之间的间隔对应的圆心角大约为90度。在操作件52自动复位的过程中，锁胆32随着操作件52反向转动复位，锁尺单元34、锁定件36保持不动，锁尺单元34和锁胆32形成相对转动，第一驱动面C1与第一离合面C2分开，此时两者的间隔对应的圆心角大于90度，第一离合机构40切换至分离状态。
锁具100需要开锁时，如图9c层所示，将钥匙***至锁胆32的锁孔321中，首先通过钥匙带动锁胆32沿第二方向（即顺时针方向）旋转第一角度（如90度），使得第一驱动部42的第二驱动面D1与第一离合部44的第二离合面D2相抵接，第一离合机构40切换至接合状态；之后，如图9d所示，将钥匙继续沿第二方向旋转第二角度（如90度），使得锁胆32驱使锁尺单元34、锁定件36随之同步转动，到达未锁定位置。在此过程中，操作件52保持不动，锁尺单元34、锁定件36相对操作件52旋转约90度，第三驱动面A1回到与第三离合面A2相抵接的位置，第二离合机构60回到接合状态。
锁具100在开锁之后，可以将钥匙拔出。在拔出钥匙之前，将钥匙按第一方向，即逆时针方向旋转一定角度，该角度为第一角度和第二角度的和，本实施例中为180度。锁胆32随着钥匙转动而使得第一驱动部42远离第二离合面D2，回到第一驱动面C1与第一离合面C2相抵接的状态，第一离合机构40回到接合状态。在此过程中，操作件52、锁尺单元34、锁定件36保持不动，第三驱动面A1保持与第三离合面A2相抵接的状态，也就是第二离合机构60保持在接合状态，锁具100整体上回到图9所示的初始状态。
应当理解地，锁具100在未锁定状态下，也可以使用钥匙锁定。此时，将钥匙***锁胆32的锁孔321中并逆时针方向旋转，使得第一驱动部42的第一驱动面C1推动第一离合部44的第一离合面C2转动，进而带动锁尺单元34、锁定件36逆时针方向转动到达锁定位置。在此过程中，操作件52保持不动、锁尺单元34相对于操作件52转动，第三驱动面A1与第三离合面A2分离，第二离合机构60切换至分离状态。锁具100在用钥匙锁定之后，可在直接拔出钥匙，第一离合机构40保持在接合状态。
对本申请锁具100来说，还可以略微调整其初始状态而实现顺时针方向转动锁定、逆时针方向转动开锁，具体地：
在未锁定状态下，如图9e所示，第一离合机构40处于接合状态，但调整为第一驱动部42的第二驱动面D1与第一离合部44的第二离合面D2抵接；第二离合机构60处于接合状态，但调整为第二驱动部62的第四驱动面B1与第二离合部64的第四离合面B2相抵接。之后的锁定、开锁过程与之前类似，如图9f所示，通过第二离合机构60的第四驱动面B1、第四离合面B2的抵接实现无钥匙锁定，钥匙开锁时第一离合机构40的接合状态切换为第一驱动面C1、第一离合面C2相抵接，在此不做赘述。
本实施例中，锁尺单元34包括锁尺主体341和第一传动件343。第一传动件343整体呈圆柱状，两端分别形成第一连接孔345和第二连接孔347，其中第一连接孔345用于连接锁尺主体341、第二连接孔347用于连接锁定件36。具体地，第一传动件343设有第二连接孔347的一端伸出至锁壳10之外，锁定件36通过螺钉、铆钉等可拆卸地连接至第二连接孔347。锁尺主体341的一端插接于第一连接孔345中，两者可以是间隙配合、也可以是紧配合固定等。在一些实施例中，锁尺主体341与第一传动件343也可以是一体结构。
锁尺主体341的另一端形成所述第一离合部44，第一离合部44与锁胆32的端面相抵接。第二离合部64设置于第一传动件343朝向锁胆32一侧的端面上，由第一传动件343沿轴向一体向外延伸。在其它实施例中，第二离合部64也可以是单独成型后组装至第一传动件343上。
如图10和图10a所示的另一实施例中，锁尺单元34包括锁尺主体341和与锁尺主体341插接相连的第一传动件343，第一离合部44设置于锁尺主体341上，第二离合部64设置于第一传动件343上。不同的是，锁尺主体341的一端穿过第一传动件343以及锁壳10后向外伸出，通过传动机构等与锁舌、锁体等连接。
本实施例中，操作件52包括旋钮521和第二传动件523。旋钮521为一端开口、一端封闭的筒状结构，锁管56、锁胆32设置于旋钮521的内部中央，旋钮521的封闭端在对应锁胆32的锁孔321位置设置所述穿孔529。旋钮521的封闭端朝向其开口端延伸设置多个连接柱525，第二传动件523对应设置多个固定孔527，螺钉等固定件穿过固定孔527后与连接柱525螺合固定，将第二传动件523连接至旋钮521。在一些实施例中，第二传动件523与旋钮521也可以是一体成型。
本实施例中，锁管56单独成型后组装至旋钮521中，具体地装配至连接柱525所围成的空间内。优选地，锁管56朝向其中相邻的两个连接柱525之间突出有卡接部58，使得锁管56和旋钮521在周向上限位，两者装配后能够同步转动。在一些实施例中，锁管56与旋钮521也可以是一体成型。
如图5所示，锁壳10包括安装座12和由安装座12的中央沿背离操作件52的方向向外延伸的套筒14。旋钮521套接于安装座12上、第二传动件523设置于安装座12中、复位件54套设于第二传动件523上，定位部59分别设置于第二传动件523和安装座12上。本实施例中，如图4和图6所示，安装座12朝向旋钮521的一端的内壁面设有台阶121，对第二传动件523在轴向上限位，使得第二传动件523不能脱离锁壳10，进而使得整个操作件52不能脱离锁壳10。较佳的，安装座12与第二传动件523之间设有轴承16，减小两者相对转动时的摩擦。较佳的，安装座12的台阶121与第二传动件523之间设有耐磨的垫片18，进一步降低磨损。
第一传动件343设置于套筒14且其两端均伸出套筒14之外中，锁尺单元34穿过第二传动件523与第一传动件343连接。第二传动件523环绕第一传动件343的相应端部，并且沿径向向内突出形成所述第二驱动部62，与第二离合部64相配合。在一些实施例中，第二驱动部62也可以由第二传动件523沿轴向向外延伸；第二离合部64也可以由第一传动件343沿径向向外延伸；或者第二驱动部62、第二离合部64皆沿轴向延伸或皆沿径向延伸，只要两者位于同一圆环上即可通过相对转动实现抵接和分开，使得第二离合机构60在分离和接合两种状态之间切换。
优选地，套筒14的外周面形成有螺纹19，可以通过螺合的方式将锁具100安装至门、窗等第一物体210上。
本申请的锁具100通过第一离合机构40、第二离合机构60的设置，可以实现钥匙锁定和无钥匙锁定，在使用上更加方便。而且，通过第二离合机构60的状态调整，可以设置为逆时针方向转动锁定或者顺时针方向转动锁定，这使得无论待锁定的第一物体210是向左旋转打开或向右旋转打开，本申请的锁具100都可以无需更换部件即可安装于其上并正常工作。相应地，锁定件36也可以具有两种状态，如图所示锁定件36为钩状结构，其钩子的方向可以向左或者向右，这可以通过翻转锁定件36来实现，以分别适配左开和右开的两种使用状态。整体上结构简单、操作方便、通用性好。
参考图11，在锁具的一个可选的实施例中，锁具100还可以包括一锁体80，锁体80例如可以由锁定件36驱动。此时，锁定件36可以是杆状结构，其一端与旋转的第二传动件523固定连接，另一端连接于所述锁体80的驱动连接部82。锁具100设置于一第一物体210，驱动所述锁体80的锁尺单元84移动以进行锁定。在本实施例中，所述锁尺单元84为呆舌，或称方舌等，即该锁尺单元84不包括用于斜舌结构的斜面，在将带有呆舌的锁具锁定或解锁时，必须操作锁具的控制部件控制呆舌的伸出或缩回。而与之相比，在使用斜舌结构的情况下，一般仅需使一物体沿与斜舌伸出方向垂直地触碰并顶挤斜舌斜面，即可推动斜舌缩回。因此，相对于斜舌结构，呆舌结构的安全性更高。
参考图12，在锁具的一个可选的实施例中，锁具100包括锁壳10、设置于锁壳10中的锁芯组件30、与锁芯组件30传动连接的反锁组件50以及锁体80，反锁组件50包括第一操作件52和第二旋钮88，第一操作件52、锁芯组件30设置于第一物体110的一侧，第一物体110的另一侧通过固定座86设置第二旋钮88。锁定件36为与锁体80连接的驱动杆，该驱动杆穿过锁体80上的驱动连接部82并与驱动连接部82传动连接。在本实施例中，该驱动杆361具有一个呈梯形的横截面，驱动连接部82形成为与该梯形横截面大致对应的梯形孔，使得锁定件36的转动能够通过与该驱动连接部82的形状配合地连接传递给锁体80。
在本实施例中，锁体80上的驱动连接部82具有另外一种设置状态，在该设置状态下，驱动连接部82旋转180°设置，此时只需将锁定件36以及第一传动件343同样旋转180°进行安装即可。其中对于所述第一传动件343的旋转，还可以提供一个额外的调节杆用于辅助安装，该调节杆具有与所述第一传动件343的传动件接收口形状配合的调节端部和较细的杆部，其能够使调节端部穿过锁体80上的驱动连接部82并转动，此时较细的杆部不会与驱动连接部82发生传动连接。由此，该调节杆能够旋转第一传动件343，从而将其调整至所需的设置状态。
与以上所述的实施例类似，具有额外的设置状态的锁具能够安装于向左打开或向右打开的第一物体上，而不需要更换锁具零件。可以理解地，为了清楚区分两种设置状态，所述第一传动件343、驱动连接部82以及所述锁定件36上均可设置用于区分两种安装状态的标识，从而防止误装。
在安装时，首先将锁壳10、第一传动件343、锁尺单元31、复位件54、第二传动件523、锁胆32、第一操作件52等依次进行组合，并安装于待锁的第一物体210的一侧。将锁体80嵌入地设置于待锁的第一物体210内部，其中所述锁体80的锁尺单元84能够相对于所述第一物体210伸出或缩回。之后，将所述锁定件36***并通过所述锁体80的驱动连接部82，使得所述锁定件36穿过所述锁体80并与第一传动件343传动连接。在这一步，如果需要调整第一传动件343的设置状态，则可使用上述调节杆对第一传动件343进行调节。在将锁定件36***到位后，即可将固定座86以及第二旋钮88依次安装于所述第一物体210的另一侧。其中，所述第二旋钮88包括用于接收所述锁定件36的接收部，所述接收部与所述锁定件36形成传动配合，从而使得所述第二旋钮88能够控制所述锁具的锁定和解锁。本实施例中，所述锁体80的锁尺单元为呆舌。
需要说明的是，以上实施例仅表达了本申请的优选实施方式，其描述较为具体和详细，但并不能因此而理解为对本申请的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，如对各个实施例中的不同特征进行组合等，这些都应属于本申请的保护范围。
