Description

外置操作手柄 技术领域
本发明涉及低压电器领域，特别是涉及一种外置操作手柄。
背景技术
目前，外部操作手柄广泛用于对诸如断路器等开关电器进行手动操作，既可以直接安装在开关柜内的开关电器上，也可以通过联接轴安装在开关柜的柜门上。外部操作手柄一般通过一个联接轴，该轴一端可与开关电器固定联接，一端与手柄装置固定联接，以便实现操作旋转手柄装置对开关电器进行关断(off)位置和闭合(on)位置切换。另外，在某些场合(如检修)用户需要将旋转手柄锁定off位置，可通过挂锁将手柄装置锁定在off装置，以禁止对开关电器的操作。此外，在正常使用情况下，在外部操作旋转手柄处于on状态(即开关柜内的开关电器闭合状态)时，开关柜的柜门不允许打开，只有当手柄处于off状态时，柜门才能打开；而在紧急情况下，要求外部操作手柄在on状态时具有柜门紧急释放功能。这种通过联接轴使用的外部操作手柄的防尘防水性能的好坏直接影响着开关柜和开关电器的电气安全。

具体实施方式
以下结合附图1至36给出的实施例，进一步说明本发明的外置操作手柄的具体实施方式。本发明的外置操作手柄不限于以下实施例的描述。
如图1所示，本发明的外置操作手柄包括，联接装置1和手柄装置2，以及连接在联接装置1和手柄装置2之间的联接轴101，联接装置1与安装在开关柜内部的开关电器3连接(例如断路器或隔离器的手柄)，手柄装置2安装在开关柜的柜门4外侧供人工操作，正常情况下，不需要打开开关柜的柜门4，直接通过手柄装置2就可以对开关电器3进行操作，例如关断(OFF)位置和闭合(ON)位置切换。此外，为了保证开关柜内部的安全，在开关电器3处于闭合状态时，连接轴101与手柄装置2保持锁定，保证开关柜的柜门4无法打开，开关柜的柜门4只有在开关电器3处于关断位置时才允许被打开，但是在紧急情况下，即使开关电器3处于闭合状态，仍旧需要将开关柜的柜门4迅速地打开，以便于人员对开关柜的内部进行观测和操作。
如图24所示，所述手柄装置2包括底座110和罩壳120组成的壳体，在罩壳120的顶侧设有供人工旋拧操作的手柄件300，在底座110的底侧设有与开关柜的柜门4配合成筒状的螺纹套130，在壳体内设有联动件410与手柄件300固定连接的，联接轴101从底侧穿过螺纹套130伸入到联动件410中连接，手柄件300通过联动件410带动联接轴101绕联接轴101的轴线转动。
联动件410的底侧设有与联接轴101滑动配合的联动轴槽411，联接轴101与联动件410连接的一侧上设有联接键102，在联动轴槽411的槽壁上一体地设有与联接键102滑动配合的联动键槽412(图11)， 联接轴101可沿轴向滑入滑出联动件410；
如图5-6所示，在联动件410的下方设有可移动的锁定件420以及与锁定件420相连的解锁件430，锁定件420的中部设有与联动轴槽411对应的锁定轴孔421，在锁定轴孔421的孔壁上设有与联动键槽412对应的锁定键孔422，联接轴101从底侧的底座110穿过锁定件420伸到联动件410中，解锁件430能够带动锁定件420沿联接轴101的径向移动，使锁定键孔422与联动键槽412错位和重合；
如图5示出当锁定键孔422与联动键槽412错位时，锁定件420能够抵在联接键102的底侧，将联接轴101与联动件410锁定，如图6示出当锁定键孔422与联动键槽412重合时，锁定件420对联接轴101无约束作用，联接轴101可自由穿过锁定键孔422和联动键槽412，以实现迅速解锁联接轴101。
本发明的外置操作手柄，通过在联动件410的底侧设置与联接键101a配合的锁定件420，使锁定机构420通过的结构便实现了对联接轴101的锁定和解锁，不需要在联接轴101上加工制作其它结构，既减少了制作的成本，又保证了联接轴101的可靠性，一石二鸟，设计巧妙。
当然，锁定件420上也可以不设置锁定轴孔421，联动轴101也不需要从锁定件420中穿过，锁定件420也可以设置在联动轴101的一侧直接阻挡和避让联接键102，或者在联接轴101上加工槽体，通过锁定件420嵌入和离开槽体对联接轴101进行锁定和解锁，都属于本发明的保护范围。
图7为联动件410转动到关断(OFF)位置时的示意图，所述联接键102成半球形，在联接键102的底侧设有弧面形的推动面104，顶侧设有弧面形的导入面105，导入面105能够便于将联接键102卡入锁定件420中，推动面104能够沿其与联接轴101轴线的连线方向，即沿联接轴101的径向推动锁定件420远离联接轴101移动，而锁定件420四周的锁定套筒1212和导向板423b以及解锁件430的作用下，锁定件420只能沿解锁件430的移动方向相应地移动，即锁定件420与解锁件430的移动方向相同，解锁件430的移动方向与关断(OFF)位置对应设置，只有在连接轴101旋转至关断位置时，才能够带动所述的联接键102移动到解锁件430的移动方向上，使推动面104能够沿联接轴101的径向推动锁定件420克服解锁件430的作用沿解锁件430的方向移动，解除对联接轴101的锁定作用，以实现联接轴101能够在关断位置时离开联动件410，在不需要联接轴101离开联动件410时，锁定件420又可以起到对联接轴101限位的作用，使本发明的外置操作手柄在安装、使用和维护时，更加的方便，而且还具有结构简单、配合可靠、结构强度高、寿命长的特点。
参照图8、10，所述罩壳120的中部设有与联动件410配合的联动底孔1211，罩壳120的底侧在联动底孔1211的边缘设有环形的限位挡槽413b，在联动件410的底侧一体地设有与限位挡槽413b滑动配合的限位挡圈413a，防止联动件410从罩壳120顶侧脱离壳体。
进一步的，所述限位挡槽413b的槽壁上设有分别对应在ON和OFF位置的限位挡块413c，在限位挡圈413a的侧面设有沿径向凸起与限位挡块413c配合的限位凸台413d，通过限位挡块413c止挡限位凸台413d，限制联动件410的极限旋转位置，进而限制了手柄件300的极限旋转位置，限位凸台413d优选为设置在靠近联动键槽412的一侧(图11)。
更进一步，所述的两个限位挡块413c到联接轴101轴线连线的夹角大于90度，通过在两个限位挡块413c的夹角设置有余量，可以补偿外置操作手柄内部零件之间，以及外置操作手柄与开关电器3之间的安装间隙，提高可靠性，考虑到零件的装配误差、实际使用场所的需求及后期各零件的磨损，两个限位挡块413c到联接轴101轴线连线的夹角优选为110度。
参照图8、12，所述罩壳120的底侧在限位挡槽413b的外侧设有成筒状的锁定套筒1212，以及连通在罩壳120侧壁与锁定套筒1212之间的解锁套筒1213，所述的锁定件420设置在锁定套筒1212的内侧，所述的解锁件430设置在解锁套筒1313的内侧，解锁件430的一端伸入到锁定套筒1212中与锁定件420连接，另一端露出罩壳120与外部动力源配合，外部动力源可以是人工按压提供，也可以是远程控制的机械。
进一步的，所述锁定套筒1212的侧壁上对应在锁定件420的两侧，设有两个相对设置的导向板423b，导向板423b相向的一侧为矩形平面，相离的一侧为弧面，矩形平面的长度方向沿锁定件420的移动方向 设置，并且两个矩形平面之间的距离大于所述的限位挡槽413b的外径，在锁定件420的两侧分别设有与导向板423b滑动配合的导向臂423a，导向臂423a的厚度小于锁定件420的厚度并在锁定件420的顶侧形成导向槽423c，在导向臂423a的两端设有倒角，通过导向臂423a与导向板423b的配合为锁定件420的移动提供引导和限位的作用，在锁定件420止挡联接键102时还能够平衡锁定件420上受到的力矩，提高可靠性和安全性，其中有个导向臂423a优选为设置在靠近锁定键孔422的一侧。
参照图12、14所示，所述解锁件430的一端设有露出罩壳120供人员操作的解锁头431，解锁头431的端面上设有与工具(如螺丝刀)配合的刀槽4311，另一端设有与锁定件420连接的锁定头432a，在锁定件420上设有与锁定头432a配合的锁定槽432b。所述锁定头432a的截面成T形，其包括锁定板432d以及连接在锁定板432d与解锁件430之间的锁定杆432e，锁定板432d卡入到锁定槽432b中，在锁定槽432b的槽壁的顶侧设有与锁定杆432e配合的避让孔432c，锁定杆432e卡入到避让孔432c中，不仅能够缩减本发明的外置操作手柄的整体结构，而且能够增大解锁件430与锁定件420之间的接触面积，提高配合的可靠性。
进一步的，在解锁件430上设有与罩壳120连接的锁定弹簧433(图2)，锁定弹簧433能够驱动解锁件430带动锁定件420向锁定联接轴101的方向移动，解锁件430上设有与所述锁定弹簧433一端配合的弹簧挡圈434，在解锁套筒1213的内壁上设有与锁定弹簧433另一端配合的弹簧环台435(图8)，弹簧挡圈434与解锁件430的解锁头431间隔设置形成解锁密封槽436，在解锁密封槽436中设有与解锁套筒1213内壁相配合的解锁密封圈437(图2)，通过解锁密封圈437与解锁套筒1213配合能够提高壳体的防水性和防尘性；通过按压解锁头431能够克服锁定弹簧433的作用使锁定件420解锁联接轴101，按压力消失后锁定弹簧433带动解锁件430和锁定件420复位，不仅结构简单、成本低，而且动作可靠，解锁速度快。当然，锁定弹簧433也可以设置在锁定件420上与锁定件420相连，也属于本发明的保护范围。
如图14-15示出解锁件430的一种实施方式，所述解锁件430成圆柱形，其包括设置在左端的解锁头431，以及设置在右端的锁定头432a，锁定头432a包括锁定板432d以及连接在锁定板432d与解锁件430之间的锁定杆432e，在解锁头431的右侧间隔设有弹簧挡圈434，弹簧挡圈434的左侧与解锁头431形成环形的解锁密封槽436，在解锁密封槽436中设有与罩壳120的解锁套筒1213配合的解锁密封圈437，弹簧挡圈434的右侧设有锁定弹簧433，锁定弹簧433套装解锁件430上将左端抵在弹簧挡圈434的右侧，右端抵在解锁套筒1213内壁上的弹簧环台435上。
图12示出的是锁定件420的顶侧视角，图13示出的是锁定件420的底侧视角，锁定件420成扁圆柱形，在锁定件420的上、下两端设有两个相对设置的导向臂423a，导向臂423a的厚度小于锁定件420的厚度并在锁定件420的顶侧形成导向槽423c，在锁定件420的中部设有与联接轴101相配合的锁定轴孔421，在锁定轴孔421的底侧孔壁上设有与联接轴101上联接键102配合的锁定键孔422，在锁定件420的左侧设有与解锁件430连接的锁定槽432b，锁定槽432b成弧形，在锁定槽432b的左侧槽壁上设有与解锁件430配合的避让孔432c。

作为一种具体实施方式：
本发明的外置操作手柄装置，包括由罩壳120、手柄件300、限制件310、底座110、螺纹套130、联动件410、锁定件420、解锁件430、T形的罩壳密封圈124、锁定弹簧433、限制弹簧312、联动密封圈417、解锁密封圈437、限制导向轴316a等组成，外置操作手柄装置可带动开关电器3在闭合(ON)和关断(OFF)两个位置进行切换，以便实现对开关电器3的操作。联动件410穿过罩壳120的联动底孔1211通过组合螺钉415与手柄件300固定连接，通过操作手柄件300可带动联动件410一起绕罩壳120的中心轴做旋转运动，即手柄罩320的罩壁321外侧的曲面绕罩壳120的罩槽321b外侧的曲面做相对旋转运动，联动件410的顶侧设有联动凸台414，联动凸台414上装有联动密封圈417，当通过组合螺钉415拧紧手柄件300和联动件410形成连接时，联动密封圈417产生压缩变形增强连接部位的密封效果。
联动件410底侧限位挡圈413a上的限位凸台413d与罩壳120的限位挡槽413b内的限位挡块413c相互配合，当限位凸台413d的侧面与右侧的限位挡块413c(图8)的侧面相接触时，外部操作手柄处于off状态；当限位凸台413d的侧面与左侧的限位挡块413c(图8)的侧面相接触时，外部操作手柄处于on状态，即通过罩壳120上左右两侧的限位挡块413c限制联动件410的旋转极限位置，进而限制了手柄件300在off和on状态的旋转极限位置，罩壳120的左侧限位挡块413c右侧侧面与右侧的限位挡块413c的左侧侧面之间(图8)的角度设计有余量，该夹角大于90°，可以补偿外部手柄和开关电器3之间的安装间隙。罩壳120与手柄件300底侧的手柄罩320配合出设有罩壳排水槽325a，手柄件300底侧的手柄罩320设有与罩壳排水槽325a对应的手柄排水槽325b，可以增加外部操作手柄的排水，增加整个手柄装置的防水效果。
限制件310设有上弹簧轴312a用来固定限制弹簧312，限制弹簧312另一端通过手柄件300的下弹簧轴312b进行固定，限制件310可在手柄件300中沿竖直方向上下移动，限制件310上设有限制杆311，当限制杆311底端的圆柱端面运动到罩壳120的限制孔311c中与限制孔311的底面相接触时，可以通过一把或多把止挡件(如挂锁)穿过手柄件300上的腰圆形的止挡孔310c将外部操作手柄锁止在off位置。当限制件310竖直向上运动，限制件310的顶侧与手柄件300的限制槽310b的顶侧齐平时，限制件310两侧的限位臂314b被手柄件300上的限位臂314b限位，同时外部操作手柄锁止功能失效，手柄件300可以绕罩壳120的中心旋转到on位置；为了防止手柄件300沿竖直方向上运动时可能发生一侧倾斜，又通过限制导向轴316a端部的圆柱面141与限制件310上的滑动臂315相切，对限制件310在竖直方向进行导向和限位。限制导向轴316a的四周设有固定筋316f，固定筋316f与手柄件300上的限制导向通孔316bb过盈配合，在限制导向通孔316bb的外侧设有限制导向盲孔316b，限制导向盲孔316b与限制导向轴316a的限制导向头316d相接触，用于对限制导向轴316a限位。
解锁件430外圆柱面穿过罩壳120的锁定套筒1212与锁定件420相连接，锁定弹簧433为一压缩弹簧，安装在解锁件430的弹簧挡圈434的右侧，一端由弹簧挡圈434的右侧限位，另一端由罩壳120的解锁套筒1213内壁上的弹簧环台435上限位，解锁件430的锁定杆432e与锁定件420的避让孔432c相接触，锁定板432d与锁定槽432b相接触，锁定件420的导向臂423a，安放在罩壳120的导向板423b上可沿水平方面运动一定位移(如附图14所示)。解锁件430的弹簧挡圈434在远离锁定弹簧433的一侧安装有解锁密封圈437，增强此处连接的密封效果。
柜门紧急释放装置如附图14所示，图5为外置操作手柄装置处于on状态时的结构示意图，图6为需要柜门4紧急打开时的外置操作手柄装置内部结构示意图。解锁件430的端面上设有与工具配合的刀槽 4311，便于人工在开关电器3处于on状态并且需要紧急打开柜门4时，可采用工具(如螺丝刀)按压解锁件430，解锁件430的锁定板432d的右侧端面与锁定件420的锁定槽432b的右侧侧壁(图12)相接触，推动锁定件420从图5运动到图6中的位置，即锁定件420的锁定键孔422和联动件410的联动键槽412重合，可使联接轴101101的成圆弧凸起210状的联接键102(图14)脱离联动件410的联动键槽412和锁定件420的锁定键孔422，进而柜门4打开，解锁件430撤销压力时，由锁定弹簧433产生的复位力将解锁件430和锁定件420返回到图5的位置。
底座110的罩壳螺纹孔117c与罩壳120的四个罩壳螺纹凸台117d通过螺钉固定连接。底座110的装配槽116与罩壳120的装配凸台116b相互配合，具有防错安装功能。底座110设有与螺纹套130相配合的底座套筒111，底座套筒111的外侧设有外螺纹，与螺纹套130内侧的内螺纹配合，螺纹套130的一端设有套筒挡圈131，套筒挡圈131成弧面形，套筒挡圈131对联接轴101导入外置操作手柄装置内部具有导向作用，套筒挡圈131的一侧上设有把持臂132，把持臂132在旋合螺纹套130时增加手持旋转螺纹套130安装的可靠性与便捷性。底座110的安装通孔114对应联接轴101在外置操作手柄装置off状态导入手柄装置内部，释放通孔115对应联接轴101在外置操作手柄装置on状态的情况下需要紧急打开柜门4时，从手柄装置内部导出。
T形的罩壳密封圈124与罩壳120的罩壳密封槽123配合安装，罩壳密封槽123的截面成U字形，在外置操作手柄装置与柜门4安装时，T形的罩壳密封圈124受到柜门4面板与罩壳120的挤压变形，增强柜门4与罩壳120连接的密封效果。
本发明的外置操作手柄装置，具有以下优点：
a、手柄件300、限制件310和手柄罩壳320的结构简单、零件少、成本低；
b、联动件410对应在off和on位置均设计有余量，可以补偿本发明的外部操作手柄和开关电器3之间的安装间隙；
c、采用迷宫密封结构、T形的罩壳密封圈124和圆形的解锁密封圈437和联动密封圈417使本发明的外部操作达到高防尘防水效果；
d、罩壳120上设有罩壳排水槽325a，可以有效提高防水效果。
进一步的，联接装置1包括联接轴101、连接件140、支架板151及螺纹套130。连接件140一侧设有仿形的连接槽144，连接槽144与联接轴101连接，另一侧设有手柄槽143，手柄槽143与开关电器3的手柄连接，并分别手柄锁紧孔145和连接锁紧孔146中的螺钉螺纹紧固连接，使开关电器3和联接轴101相对连接件140沿轴向无相对运动。联接轴101的设有联接键102的另一端沿外部操作手柄的螺纹套130导入壳体内部进行连接。通过调节支架板151上的调整螺钉155对联接轴101在竖直方向的下垂位移进行补偿，与螺纹套130一起整体提高联接装置1的导向作用，便于联接轴101顺利导入螺纹套130的内部联接。支架板151设有第一卡扣1551a和第二卡扣1552a，第一卡扣1551a和第二卡扣1552a分别与开关电器3上的第一卡槽1551b和第二卡槽1552b(进行卡扣连接。
在具有本专利的联接装置的开关电器3中，开关电器3可以安装在配电柜或控制柜内，手柄装置2可以安装在柜门4上，人通过操作手柄装置2将力传递给联接装置1，进而带动开关电器3进行电路连接/断开操作。本发明的外置操作手柄还具有以下特点：
a、结构简单、零件少、成本低；
b、联接装置1的校准臂152具有垂直方向上的微调节作用，使联接轴101与螺纹套130对中，方便实用；
c、螺纹套130对联接轴101具有导向对中功能。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
