具体实施方式
下面结合附图及具体实施例就本发明的技术方案做进一步的说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明实施例提出一种用于断路器的互锁装置。如图1至图5所示，图1为本发明互锁装置一实施例的结构示意图，图2为图1中互锁装置的爆炸示意图，图3为本发明实施例互锁装置与断路器的连接示意图，图4 为本发明实施例断路器装置的第一状态示意图，图5为本发明实施例断路器装置的第二状态示意图，其中，断路器的数量为两个，断路器包括第一断路器100和第二断路器200，所述第一断路器100上设有第一开关把手110，所述第二断路器200上设有第二开关把手210。在本发明实施例中，该互锁装置包括，固定板300，夹持于所述第一断路器100和第二断路器200之间，设有用于与所述第一断路器100和/或第二断路器200卡合固定的卡合结构；滑动板400，设于所述固定板300上，可相对于所述固定板300往复滑动，且设有锁定部410；所述滑动板400滑动至第一预设位置时，所述锁定部410限制所述第一开关把手110转动，且所述锁定部410避开所述第二开关把手210，以使所述第二开关把手210可以转动；所述滑动板400滑动至第二预设位置时，所述锁定部410限制所述第二开关把手210转动，且所述锁定部410避开所述第一开关把手110，以使所述第一开关把手110可以转动。
在本实施例中，用户可以通过扳动第一开关把手110，而使得第一断路器100开启或关闭。同理，用户也可以通过扳动第二开关把手210，而使得第二断路器200开启或关闭。如图4所示，第一断路器100处于关闭状态，第二断路器200处于开启状态。如图5所示，第一断路器100处于开启状态，第二断路器200处于关闭状态。
在一具体实施例中，固定板300的形状可以与断路器的侧面适配，即固定板300的形状与断路器的用于与固定板300贴合的侧壁适配，从而可以使得第一断路器100和第二断路器200能够更加牢固地夹持住固定板300，提高互锁装置安装的牢固性和可靠性。
固定板300可以通过卡合结构同时与第一断路器100和第二断路器200卡合固定连接，牢固性更高。为了降低互锁装置的结构的复杂度，固定板300还可以只与其中一个断路器固定连接。本实施例及以下各个实施例，以 固定板300只与第一断路器100卡合固定连接为例进行说明。卡合结构可以为卡扣。通过设置固定板300，并通过固定板300直接卡合固定于断路器上，从而不需要额外设置专门用于将互锁装置固定于断路器上的结构件(如支架)，有效地减小了互锁装置的安装空间，并减小了断路器装置的体积。
固定板300的厚度可以根据实际需要进行设置，可以设置为薄片形式。从而能够进一步减小互锁装置的安装空间。
在一具体实施例中，所述卡合结构包括用于卡持所述断路器的两个相对的侧面的卡夹510，以及用于卡持所述断路器的底部的限位支脚520。可选的，如图1所示，卡夹510大体呈S型设置，具有一定的弹性，从而不仅便于安装，且可以更加牢固的夹持住断路器。可选的，卡夹510设于固定板300的上方，且两个卡夹510相对设置。限位支脚520的宽度可以略大些，从而可以更加牢固地起到支撑作用。可选的，限位支脚520也可以具有一定的弹性，从而不仅便于安装，且可以更加牢固的夹持住断路器。可选的，卡合结构顶部也可以设置一个限位支脚520，从而可以更加牢固地将互锁装置固定于断路器上。
通过卡合结构将固定板300卡合固定于断路器上，不仅安装简单方便快速，且结构简单，容易实现。
应当说明的是，在其他实施例中，固定板300还可以通过螺钉固定于第一断路器100和/或第二断路器200的壳体上。
在一具体实施例中，所述滑动板400上还向上凸设有手持部420。在另一具体实施例中该手持部420为由滑动板400的端部向上翻折形成的翻边。通过设置手持部420，使得用户可以通过握持该手持部420而控制滑动板400的滑动，更加便于用户拨动滑动板400。
锁定部410的具体结构可以根据实际需要进行设置，只要能够起到限制其中一个开关把手，并可以避开另一开关把手即可。可选的，锁定部410 为由所述滑动板400的侧边沿垂直于所述滑动板400滑动方向延伸的舌片。可选的，该舌片的端部向上延伸形成弧状，从而能够更好的与开关把手的握持部抵接，以限制该开关把手转动。
在锁定部410可以限制第一开关把手110转动、且还可以避开第二开关把手210时，此时滑动板400的位置均可以称之为第一预设位置；同理，在锁定部410可以限制第二开关把手210转动，且还可以避开第一开关把手110时，此时滑动板400的位置均可以称之为第二预设位置。
如图4所示，此时滑动板400位于第一预设位置，锁定部410限制第一开关把手110转动，第一开关把手110此时的位置使得第一断路器100处于关闭状态，可选的，锁定部410位于第一开关把手110的旋转部上方，并与第一开关把手110的握持部抵接，从而防止第一开关把手110转动。同时，锁定部410避开了第二开关把手210，第二开关把手210可以在用户的扳动下转动，此时，第二开关把手210向上扳动使得第二断路器200处于开启状态。可选的，所述滑动板400滑动至所述第一预设位置、且所述第二断路器200处于开启状态时，所述第二开关把手210位于所述锁定部410的朝向所述第二断路器200的一侧，且所述第二开关把手210阻碍所述滑动板400向所述第二预设位置移动，即，此时在滑动板400若向第二预设位置的方向滑动，则第二开关把手210将会与锁定部410抵接，从而防止了滑动板400滑动至第二预设位置，从而使得锁定部410始终能够避开第二开关把手210。
当需要切换断路器时，用户可以先扳动第二开关把手210，使第二断路器200处于关闭状态，然后再拨动滑动板400，使得滑动板400向第二预设位置的方向滑动。如图5所示，此时滑动板400位于第二预设位置，锁定部410限制第二开关把手210转动，第二开关把手210此时的位置使得第二断路器200处于关闭状态，可选的，锁定部410位于第二开关把手210 的旋转部上方，并与第二开关把手210的握持部抵接，从而防止第二开关把手210转动。同时，锁定部410避开了第一开关把手110，第一开关把手110可以在用户的扳动下转动，此时，用户可以向上扳动第一开关把手110使得第一断路器100处于开启状态。可选的，所述滑动板400滑动至所述第二预设位置、且所述第一断路器100处于开启状态时，所述第一开关把手110位于所述锁定部410的朝向所述第一断路器100的一侧，且所述第一开关把手110阻碍所述滑动板400向所述第一预设位置移动，即，此时在滑动板400若向第一预设位置的方向滑动，则第一开关把手110将会与锁定部410抵接，从而防止了滑动板400滑动至第一预设位置，从而使得锁定部410始终能够避开第一开关把手110。
可选的，滑动板400还可以在第一预设位置固定，从而防止滑动板400在外力作用下晃动而误滑动至第二预设位置。可选的，滑动板400还可以在第二预设位置固定，从而防止滑动板400在外力作用下晃动而误滑动至第一预设位置。可选的，滑动板400在第一预设位置和第二预设位置的固定方式可以为卡合固定，即滑动板400在滑动至第一预设位置或第二预设位置时，可以与固定板300卡合固定，不仅结构简单，且比较牢固。
本发明实施例提供的用于断路器的互锁装置，通过设置夹持于第一断路器100和第二断路器200之间的固定板300，且固定板300上设有用于与断路器卡合固定的卡合结构，使得固定板300可以直接卡合固定于断路器上，并在固定板300上设置可相对固定板300往复滑动的滑动板400，滑动板400上设有锁定部410，滑动板400滑动至第一预设位置时，锁定部410限制第一开关把手110转动，且锁定部410避开第二开关把手210，以使第二开关把手210可以转动；滑动板400滑动至第二预设位置时，锁定部410限制第二开关把手210转动，且锁定部410避开第一开关把手110，以使第一开关把手110可以转动。从而本发明实施例提供的互锁装置直接通过固 定板300卡合固定于断路器上即可，不需要额外设置专门用于将互锁装置固定于断路器上的结构件(如支架)，有效地减小了互锁装置的安装空间，并减小了断路器装置的体积。
进一步地，图6为本发明实施例互锁装置的局部结构示意图，如图6所示，所述固定板300上设有支撑部600，所述支撑部600上凸设有导向件610，所述滑动板400上开设有与所述导向件610适配的滑槽430，所述滑动板400通过所述滑槽430与所述导向件610的配合相对于所述固定板300往复滑动。
在一具体实施例中，支撑部600垂直于固定板300设置。可选的，支撑部600设于固定板300的顶端。可选的，支撑部600还可以与上述限位支脚520相对设置，从而在两个卡夹510、底部的限位支脚520和顶部的支撑部600的夹持作用下，能够更加牢固的将互锁装置固定于断路器上。
导向件610的具体结构可以根据实际需要进行设置。例如，可以为导块、导条、导柱等。可选的，滑槽430呈长方形状设置。
在一具体实施例中，为了进一步提高互锁装置的牢固性，所述互锁装置还包括与所述支撑部600固定连接的盖板700，所述盖板700设于所述支撑部600上方，所述滑动板400在所述盖板700与所述支撑部600之间滑动，从而有效地防止了滑动板400从支撑部600上脱落。
盖板700可以与支撑部600一体成型，并形成一中空的滑动空间，使得滑动板400可以在该空间内滑动。
在一具体实施例中，盖板700还可以固定于导向件610上。例如，盖板700可以固定于导向件610的顶端。盖板700可以卡合固定于导向件610的顶端。
在一具体实施例中，如图6所示，导向件610包括螺柱611，盖板700通过螺钉固定于所述螺柱611上，不仅更加方便的将盖板700固定于导向 件610上，而且更加牢固，便于生产。可选的，所述导向件610还包括凸出板612，所述凸出板612顶端设有卡块，所述盖板700对应所述卡块的位置开设有与所述卡块适配的卡槽。可选的，凸出板612的形状为“凸”字形。
在本实施例中，导向件610的数量为两个，一个为螺柱611，一个为凸出板612，从而仅需要一个螺钉即可将盖板700固定，并且通过凸出板612的卡块与盖板700上的卡槽的配合可以防止盖板700发生旋转，不仅节约螺钉，而且安装更加方便，结构简单，节约成本。
本发明实施例还提出一种断路器装置，该断路器装置包括第一断路器100、第二断路器200和互锁装置，所述第一断路器100上设有第一开关把手110，所述第二断路器200上设有第二开关把手210，该互锁装置的具体结构可参照上述实施例，由于本断路器装置采用了上述互锁装置所有实施例的全部技术方案，因此同样具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
图7为本发明实施例断路器装置一实施例的局部结构示意图，在一具体实施例中，如图7所示，断路器装置还包括用于安装第一断路器100和第二断路器200的导轨800。
在装配时，先将互锁装置固定于第一断路器100上，固定方式可以参照上述实施例。然后再将第一断路器100安装于导轨800上，最后将第二断路器200安装于导轨800上，并使得第一断路器100与第二断路器200夹持固定所述固定板300。
进一步的，所述滑动板400滑动至所述第一预设位置、且所述第二断路器200处于开启状态时，所述第二开关把手210位于所述锁定部410的朝向所述第二断路器200的一侧，且所述第二开关把手210阻碍所述滑动板400向所述第二预设位置移动；所述滑动板400滑动至所述第二预设位 置、且所述第一断路器100处于开启状态时，所述第一开关把手110位于所述锁定部410的朝向所述第一断路器100的一侧，且所述第一开关把手110阻碍所述滑动板400向所述第一预设位置移动。
应当说明的是，本发明的各个实施例的技术方案可以相互结合，但是必须是以本领域的技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本发明要求的保护范围之内。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
