一种抽屉电操双工位联锁机构及其使用方法 技术领域
本发明涉及联锁机构领域，具体涉及一种抽屉电操双工位联锁机构及其使用方法。
背景技术
可抽出式抽屉在断路器配有电动操作机构时会遇到需要配合摇把摇进或摇出的情况，此时应先进行分闸，再安装摇把，摇进或摇出配电单元，若因操作人员错误操作，在没有分闸的情况下，直接摇进或摇出配电单元，可能会出现被电弧烧伤或者造成电源拉弧短路的情况。
现有的可抽出式抽屉断路器配的电动配电单元没有针对上述情况的保护措施，存在较大的安全隐患。

所述回复轴至少有一端与支撑体的配合处为非圆轴。
由于采用了上述技术方案，可避免因回复轴旋转导致卡槽与卡块难以对准。
进一步地，还包括支撑板，所述支撑板设于壳体内，所述支撑板上设有与第一限位段匹配的支撑滑道，所述第一限位段的两端分别设有可 限制于支撑滑道的第一限位部和第二限位部；所述支撑滑道套设于第一限位段，并设于第一限位部和第二限位部之间。
由于采用了上述技术方案，可对操作轴的移动距离进行限定，提高机构的稳定性。
进一步地，所述第二限位部为非圆轴。
由于采用了上述技术方案，可避免因操作轴旋转导致卡槽与卡块难以对准。
进一步地，所述回复轴的挡位部在弹性元件的作用下抵于支撑体内壁时，所述回复轴与目标按钮之间形成有移动间距，所述第一限位部和第二限位部之间的距离、支撑板与壳体的间距、以及支撑板与导向板的距离分别与移动间距匹配。
进一步地，所述操作段的长度大于移动间距。
进一步地，所述支撑滑道的长度与导向部的长度匹配，所述支撑滑道的位置与导向部相对应，所述支撑滑道的一端向外延伸有装配部，所述第二限位部靠近第二限位段，所述装配部的形状与第二限位部的形状匹配。
由于采用了上述技术方案，便于支撑板与操作轴装配。
进一步地，所述操作滑道的长度大于等于插入孔的直径与操作段的直径之和。
相应地，本发明还公开了一种的抽屉电操双工位联锁机构的使用方法，包括如下步骤：
解锁步骤：向壳体内按压操作轴，第一限位部抵于支撑板，第二限位部抵于导向板，回复轴在操作轴的作用下作用于目标按钮；
开启插入孔步骤：操作轴保持按入状态，移动段与第一工位定位部匹配，拨动操作轴，使移动段进入滑道并沿滑道移动至第二工位定位部，操作 挡片随操作轴移动，开启插入孔；
封闭插入孔步骤：向壳体内按压操作轴，使移动段与第二工位定位部匹配，拨动操作轴，使移动段进入滑道并沿滑道移动至第一工位定位部，操作挡片在操作轴的带动下重新封闭插入孔，卡块与卡槽匹配，弹簧作用于回复轴，将回复轴顶出，并带动操作轴回弹复位，使得第二限位段位于第一工位定位部。
进一步地，在开启插入孔步骤中，当插入孔开启后，向壳体外拉出操作轴，使第二限位段与第二工位定位部匹配，固定操作轴。
综上所述，由于采用了上述技术方案，本发明的有益效果是：
1、本发明可对插入孔进行遮挡，避免操作人员错误操作，提高安全性能。
2、本发明的操作轴可自动复位。
3、本发明可对操作轴的移动距离进行限定，提高机构的稳定性。

还包括回复机构6，所述回复机构6包括支撑体601、回复轴602和 弹性元件603，所述支撑体601设于壳体1内，所述回复轴602和弹性元件603设于支撑体601内，所述回复轴602的两端分别伸出支撑体601与支撑体601可活动连接，所述回复轴602上设有可限制于支撑体601内壁的挡位部，所述弹性元件603作用于挡位部并可使挡位部抵于支撑体601的内壁，所述回复轴602靠近挡位部的一端与第二限位段204匹配、另一端与目标按钮5匹配。优选的，弹性元件603为弹簧。
所述回复轴602与第二限位段204匹配的一端设于第一工位定位部402处，所述回复轴602与滑道401匹配的一侧设有卡槽604，所述第二限位段204向回复轴602所在的方向延伸有卡块205，所述第二限位段204位于第一工位定位部402时，所述卡块205与卡槽604相互配合。具体地说，在操作轴2位于第一工位定位部402时，回复机构6可将操作轴2顶出，使得第二限位段204与第一工位定位部402配合，由于第二限位段204无法通过滑道401，故实现操作轴2的自锁；若想解除操作轴2的自锁，则需向壳体1内按压操作轴2，操作轴2作用于回复轴602，使得弹性元件603收缩，直至回复轴602作用于目标按钮5，此时移动段203与第一工位定位部402配合，解除自锁，可拨动操作轴2使移动段203进入滑道401，并沿滑道401移动。
所述回复轴602至少有一端与支撑体601的配合处为非圆轴。具体地说，可避免因回复轴602旋转导致卡槽604与卡块205难以对准。在本实施例中，回复轴602靠近目标按钮5的一端为方轴。
还包括支撑板7，所述支撑板7设于壳体1内，所述支撑板7上设有与第一限位段202匹配的支撑滑道8，所述第一限位段202的两端分别设有可限制于支撑滑道8的第一限位部9和第二限位部10；所述支撑滑道8套设于第一限位段202，并设于第一限位部9和第二限位部10之间。具体地说，可对操作轴2的移动距离进行限定，提高机构的稳定性。
所述第二限位部10为非圆轴。具体地说，可避免因操作轴2旋转导致卡槽604与卡块205难以对准。在本实施例中，所述第二限位部10为方轴。
所述回复轴602的挡位部在弹性元件603的作用下抵于支撑体601内壁时，所述回复轴602与目标按钮5之间形成有移动间距，所述第一限位部9和第二限位部10之间的距离、支撑板7与壳体1的间距、以及支撑板7与导向板4的距离分别与移动间距匹配。
所述操作段201的长度大于移动间距。
所述支撑滑道8的长度与导向部的长度匹配，所述支撑滑道8的位置与导向部相对应，所述支撑滑道8的一端向外延伸有装配部，所述第二限位部10靠近第二限位段204，所述装配部的形状与第二限位部10的形状匹配。具体地说，便于支撑板7与操作轴2装配。
所述操作滑道101的长度大于等于插入孔102的直径与操作段201的直径之和。
在本实施例中，壳体1为可抽出式配电单元，目标按钮5为分闸按钮，插入孔102可供摇把插入，通过转动摇把使配电单元摇进或摇出。在没有分闸的情况下，操作轴2位于第一工位，此时第二限位段204位于第一工位定位部402，卡块205与卡槽604配合，第一限位部9抵于操作挡片3，第二限位部10抵于支撑板7，操作挡片3封闭插入孔102，摇把无法自插入孔102插入。向配电单元内按压操作轴2，第一限位部9抵于支撑板7，第二限位部10抵于导向板4，回复轴602在操作轴2的作用下作用于分闸按钮，完成分闸。此时移动段203与第一工位定位部402匹配，拨动操作轴2，使移动段203进入滑道401并沿滑道401移动至第二工位定位部403，操作挡片3随操作轴2移动，开启插入孔102，向配电单元外拉出操作轴2，使第二限位段204与第二工位定位部403匹配， 固定操作轴2，此时可将摇把自插入孔102处插入。需要重新封闭插入孔102时，向配电单元内按压操作轴2，使移动段203与第二工位定位部403匹配，拨动操作轴2，使移动段203进入滑道401并沿滑道401移动至第一工位定位部402，操作挡片3在操作轴2的带动下重新封闭插入孔102，此时卡块205与卡槽604重新匹配，弹簧作用于回复轴602，将回复轴602顶出，并带动操作轴2回弹复位，此时第二限位段204位于第一工位定位部402。
