如图6-7所示，本申请的改进点在于，在外壳1的操作端11还转动连接有盖板4，所述盖板4设有操作部42和第二驱动部43，盖板4在回收位置和打开位置之间转动，盖板4转动到回收位置时，操作部42靠近操作端11端面，盖 板4转动到打开位置时，第二驱动部43驱动锁定机构解锁，操作部42远离操作端11端面用于拉拔断路器，由盖板4形成断路器的拉拔解锁结构。通过操作部42能够将插入式断路器从机柜中拉拔出来，可以直接使用操作部42施力，也可以在操作部42上装配拆卸工具，以便施加更大的拉拔力。所述盖板4和锁定机构形成断路器的拉拔锁定结构，所述拉拔锁定结构以及应用该拉拔锁定结构的插入式断路器，设有能收起的盖板4，在拆卸断路器时，打开盖板4，盖板4的第二驱动部43同时解锁锁定机构，且盖板4打开后的操作部42可以施加拉拔力或与拆卸工具配合以拉拔断路器，相比现在通过按钮件拉拔，具备结构简单、稳定性强且方便拉拔的优点。
优选的，盖板4转动到回收位置时，盖板4平行于外壳1的操作端11端面，盖板4转动到打开位置时，盖板4与操作端11端面形成夹角，优选盖板4与操作端11端面之间的夹角为90°，即盖板4垂直于操作端11端面。
优选的，如图2、6-11所示，在外壳1的操作端11端面开设有容纳槽14，所述容纳槽14位于手柄机构2一侧，图中位于手柄机构2上侧；盖板4转动到回收位置时，盖合容纳槽14。在盖板4的两端分别设置转动部41和操作部42，盖板4还设有可以延伸至外壳1内部的第二驱动部43，由转动部41与外壳1转动连接，第二驱动部43可以凸起设置在转动部41远离操作部42的一侧。优选的，转动部41和操作部42凸起设置在盖板4面向外壳1的操作端11端面的同一侧，盖板4的另一侧为平面区45，在盖板4盖合容纳槽14时，转动部41和操作部42被容纳于容纳槽14内，由平面区45与外壳1的外部保持平整，即平面区45与操作端11端面保持平整，此时盖板4与外壳1形成一体式结构，所述盖板4同时起到盖板4遮挡的作用和拉拔件的作用，相比通过按钮件拉拔，具备结构简单、美观、和方便拉拔的优点。
所述操作部42为凸出设置于盖板4一侧的凸台，操作部42设置有用于施加拉拔力的操作面421，所述操作面421与盖板4面向外壳1一侧相交，位于操作部42靠近转动部41的一侧，盖板4转动到打开位置时，与外壳1的操作端11端面相对，用于施加拉拔力或者与拆卸工具配合以实现拉拔。其中，操作部421的凸台可以是弧形凸台或环形凸台或平面凸台或其它结构，由弧形凸台的凹面、环形凸台的中心孔孔壁或平面凸台的侧壁作为操作面421，优选操作面421为弧形面，便于手指或者拆卸工具施加。另外，在操作部42的表面设置有多个防滑凸棱，优选的，在操作部42远离转动部41的一侧侧壁作为推动面422，所述推动面422设有多个防滑凸棱，通过操作推动面422利于打开盖板4。
优选，转动部41与紧邻手柄机构2的外壳1转动连接，其中第二驱动部43可以设置在转动部41远离操作部42的一侧，第二驱动部43可以是凸台或杆状结构，在容纳槽14一端开设有与外壳1内部连通的开口，转动部41连接在该开口处，使第二驱动部43可以延伸至外壳1的内部与锁定机构配合，优选的，开口设置在靠近手柄机构2的一侧，在盖板4盖合于容纳槽14时，操作部42位于容纳槽14远离手柄机构2的一端，转动部41位于手柄机构2与操作部42之间。当然，也可以将转动部41设置在远离手柄机构2的一侧，在盖板4盖合于容纳槽14时，操作部42位于转动部41和手柄机构2之间，这样操作相对不是很方便。
特别的，在盖板4靠近手柄机构2的一端设有限位部46，在手柄机构2转动至合闸位置时，手柄机构2与限位部46配合使盖板4无法从回收位置转动到打开位置，防止在合闸状态下打开盖板4，进行拉拔操作以提高用电安全。本实施例中限位部46由平面区45靠近手柄机构2一端的区域形成。优选的，盖板4转动到打开位置时，盖板4对手柄机构2限位使手柄机构2无法从分闸位置转动至合闸位置，防止在拉拔时合闸以提高用电安全。
进一步的，在操作部42设置联动孔47，在联动孔47内装配联动轴6，当操作端11端面设置多个盖板4，如断路器为多极断路器，每个断路器极设置有一个盖板4时，由联动轴6将相邻两个盖板4联动连接，从而有利于同时拉拔多极断路器。断路器为多极断路器时，不一定是每个断路器极设置盖板4、锁定机构，至少包括一个盖板4，盖板4对应的断路器极设置锁定机构，如3P断路器时，可以是中间断路器极设置盖板4、锁定机构，也可以是每极都设置盖板4、锁定机构；4P时，中间两个断路器极设置盖板4、锁定机构，也可以是每极都设置盖板4、锁定机构。
另外，在盖板4与外壳1之间还设置有复位弹簧5，所述复位弹簧5与盖板4同轴转动装配，复位弹簧5的两个弹性臂分别与盖板4、外壳1配合用于为盖板4提供复位力，驱动盖板4向回收位置即向盖合容纳槽14的方向转动。
优选的，所述手柄机构2也能用于解锁锁定机构，所述手柄机构2能够转动到合闸位置、分闸位置和解锁位置，所述分闸位置位于合闸位置和解锁位置之间，所述手柄机构2设有第一驱动部21，在手柄机构2从分闸位置转动到解锁位置时，第一驱动部21驱动锁定机构解锁。
结合图1-8、11-17提供插入式断路器的第一实施例，在本实施例中，在外壳1的操作端11配合设有拉拔解锁结构。
如图1-8所示，所述外壳1的两端分别作为操作端11和接线端12，连接在操作端11与接线端12之间的外壳1侧壁设有限位孔13，在操作端11端面分别开设有手柄孔和容纳槽14，其中手柄孔位于操作端11端面远离限位孔13的一侧，容纳槽14位于操作端11端面靠近限位孔13的一侧，在手柄孔下方的外壳1内侧壁设有第一连接部161，手柄机构2包括手柄本体，手柄本体包括一体成型的转动连接部和把手部，转动连接部与第一连接部161转动配合，把手部连接在转动连接部的一侧并从手柄孔伸出外壳1，在把手部的一侧凸出设有作为第一驱动部21的凸台，所述第一驱动部21与把手部分别位于转动连接部的两侧。
所述容纳槽14靠近手柄机构2的一端设有开口，所述开口与外壳1的内部连通，在开口处的外壳1内侧壁设有连接孔15，连接孔15内装配有连接轴，使盖板4与复位弹簧5同轴装配于连接轴上，开口处在装配盖板4和复位弹簧5后，可以遮挡开口，或者，开口处由外壳1内壁其他结构遮挡，仅供可以驱动锁定机构的第二驱动部43伸入，防止异物进入外壳1的内部，容纳槽14靠近开口的槽底壁端部用于与复位弹簧5的一个弹性臂抵接，容纳槽14远离开口一侧的槽底凹陷形成弧形凹陷，所述弧形凹陷可以对应容纳盖板4的操作部42，使盖板4盖合于容纳槽14时，使盖板4与外壳1的外侧保持平整，容纳槽14远离手柄机构2的一端敞开并由盖板4封闭。
在本实施例中，锁定机构对应设置在容纳槽14的下方，锁定机构包括锁定件32、解锁件31以及弹性件33，其中锁定件32设置于限位孔13的一侧，本实施例的锁定件32优选与外壳1滑动配合，当然也可以与外壳1转动连接，锁定件32设有锁定部321和配合部322，由弹性件33驱动锁定件32使锁定部321伸出限位孔13，此时锁定机构处于锁定状态，解锁件31转动装配在手柄机构2与锁定件32之间，解锁件31设有第一解锁部311、第二解锁部312和第三驱动部313，盖板4转动到打开位置时，盖板4的第二驱动部43与第二解锁部311配合驱动解锁件31转动，解锁件31通过第三驱动部313驱动锁定件32使锁定部321缩回外壳1内，此时锁定机构处于解锁状态，在手柄机构2转动至解锁位置时，第一驱动部21与第一解锁部311配合驱动解锁件31转动，使第三驱动部313按压配合部322以驱动锁定部321缩回外壳1内。
具体如图11所示，在限位孔13与容纳槽14之间设有第二连接部162，第二连接部162对应于容纳槽14的下方，在图11中，第二连接部162位于容纳 槽14的右侧，解锁件31通过第二连接部162与外壳1转动连接，至少在限位孔13的一侧设有滑动限位部，锁定件32与滑动限位部滑动配合，使锁定件32在弹性件33和解锁件31的驱动下在限位孔13的一侧做直线运动，当然，也可以不设置滑动限位部，锁定件32转动装配在限位孔13的一侧，由弹性件33和解锁件31驱动锁定件32转动，使得锁定部321伸出限位孔13或缩回外壳1内。
在锁定件32面向限位孔13的一侧设置锁定部321和配合部322，其中锁定部321为凸出设置的凸台结构，锁定部321与限位孔13配合，配合部322为设置在锁定件32一侧的斜面，配合部322可以与解锁件31的第三驱动部313配合，另外，解锁件31对应位于容纳槽14的下方，在解锁件3面向容纳槽14的一侧设有第二解锁部312，设置在盖板4上的第二驱动部43可以延伸至外壳1的内部，由第二驱动部43与第二解锁部312配合以驱动解锁件31进而驱动锁定件32，使锁定部321缩回外壳1内，当然，当解锁件31不设第二驱动部43时，直接由手柄机构2摆动至解锁位置同样可以驱动解锁件31使锁定件32解锁。
结合6-8提供一种解锁件31的具体结构，所述解锁件31包括第一转动臂和第二转动臂，所述第一转动臂与第二转动臂的一端连接形成转动部41，由转动部41与第二连接部162转动配合，第一转动臂的另一端端部作为第一解锁部311与手柄机构2的第一驱动部21配合，在第一转动臂的中部凸出设有凸台，所述凸台作为第二解锁部312位于面向盖板4的一侧，第二转动臂的另一端作为第三驱动部313与锁定件32的配合部322抵接，图中第三驱动部313与斜面的配合部322相贴合。需要说明的是，第二解锁部312的位置与第二驱动部43的位置相关，第二解锁部312的位置不限于第一转动臂的中部。
所述锁定件32整体呈块状，在锁定件32面向限位孔13的一侧设有锁定部321和配合部322，所述锁定部321为凸出设置于锁定件32一侧的凸台，使得锁定件32面向限位孔13的一侧整体呈“凸”字形，在与锁定部321同侧的锁定件32开设有L形槽，所述L形槽面向限位孔13的一侧侧壁为倾斜斜面，所述倾斜斜面为配合部322用于与解锁件31抵接，如图6-8所示，配合部322远离解锁件31的一侧较高，配合部322靠近解锁件31的一侧较低，配合部322优选可以与第二转动臂的一侧贴合，以提高两者的配合程度；在背对限位孔13一侧的锁定件32本体凸出设有凸台结构，在所述凸台结构的边角处开设有缺口槽，在触头支持由合闸位置转至分闸位置时，缺口槽可以避让触头支持，在触头支持位于合闸位置时，缺口槽的一侧可以与触头支持抵接，以限制锁定机构解锁，在触头支持位于分闸位置时，且锁定件32处于解锁状态缩入壳体内部时，缺口槽的一侧可以与触头支持抵接，以限制触头支持合闸。在紧邻凸台结构的一侧开设有装配孔，弹性件33配合装配于装配孔与外壳1的内侧壁之间，也就是弹性件33的两端分别与第三配合部322、外壳1内侧壁抵接，从而使弹性件33发生形变以驱动锁定件32在外壳1内滑动。
操作机构7转动装配在锁定机构的下方，操作机构7包括与外壳1转动连接的触头支持，在触头支持转动装配有跳扣和锁扣，所述跳扣与锁扣的一端搭扣配合，触头支持通过一个连杆与手柄机构2联动连接，动触头通过动触头弹簧安装在触头支持上，触头支持位于锁定件32的一侧，在断路器合闸时，触头支持上的凸起的限位面转动到与锁定件32对应的位置，由触头支持与锁定件32限位配合，阻挡锁定件32移动以限制锁定部321缩回外壳1内，在断路器分闸时，由触头支持的限位面转动到避让锁定件32的位置。在断路器位于分闸位置时，且锁定件32处于解锁状态缩入外壳1内部时，缺口槽的一侧可以与触头支持抵接，以限制触头支持合闸。
结合图1-7、12-14提供盖板4的第一种实施例，所述盖板4包括盖板本体， 盖板本体的宽度与操作端11端面的宽度相同，盖板本体的两端分别设置有操作部42和转动部41，其中操作部42与转动部41凸出位于盖板本体的同一侧，盖板本体未设置转动部41和操作部42的另一侧为平面区45，在盖合容纳槽14后，由平面区45与外壳1的外部保持平整。如图12-14所示，转动部41为凸出设置于盖板本体一侧的柱形凸台，在转动部41的中部设有轴孔413，在该轴孔413与连接孔15内装配连接轴可以将盖板4转动装配于外壳1，在转动部41的一端端面开设有安装槽411，在安装槽411的槽底设有贯穿转动部41的轴孔413，复位弹簧5装配于安装槽411，复位弹簧5优选为套设于连接轴的扭簧，在安装槽411的一侧设有缺口412，复位弹簧5的一个弹性臂从缺口412伸出与外壳1抵接，另一弹性臂与缺口412的一侧抵接；在转动部41远离操作部42的一侧外侧部凸出设有凸台结构，该凸台结构作为第二驱动部43用于与解锁件31的第二解锁部312配合。
所述操作部42为设置于盖板本体一侧的环形凸台，环形凸台的中心孔孔壁作为操作面421，且中心孔的中心轴线与安装槽411的中心轴线相平行，操作部42的外径大于转动部41的外径，也就是操作部42的一侧更为凸出，在盖板4盖合于容纳槽14时，操作部42的一侧可以与安装槽411的弧形凹陷抵接，打开盖板4后，拆卸工具可以插入中心孔内与操作面421贴合；在操作部42远离转动部41的一侧侧壁作为推动面422，也就是图中操作部42远离转动部41的一侧弧形外侧壁作为推动面422，所述推动面422设有多个防滑凸棱，在本实施例中，推动面422的宽度最大，在环形凸台靠近连接部的一侧宽度较小，在操作部42远离转动部41的一端设置有联动孔47，在所述联动孔47内可以装配联动轴6，使相邻的两个盖板本体可以联动连接。
另外，在操作部42与转动部41之间连接有加强部44，以提高盖板4的机械强度；由背对转动部41、操作部42以及加强部44一侧的盖板本体作为平面区45，在盖板4盖合于容纳槽14，由平面区45与外壳1的外部保持平整，由平面区45的一端作为限位部46与手柄机构2限位配合，也就是限位部46位于平面区45靠近手柄机构2的一端。在手柄机构2转动至合闸位置时，手柄机构2位于限位部46的上部，由手柄机构2限制盖板4被打开。
需要说明的是，在本结构中，盖板4的转动部41与靠近手柄机构2一侧的外壳1转动连接，操作部42位于远离手柄机构2的一侧，但盖板4的连接方式不限于此，也就是，转动部41可以连接在远离手柄机构2一侧的外壳1，此时操作部42位于靠近手柄机构2的一侧，此时，限位部46与操作部42位于盖板本体的同一端，或者，操作部42兼做限位部46，如此，在手柄机构2转动至合闸位置时，手柄机构2也可以限制盖板4被打开，在手柄机构2摆动至分闸位置时，盖板4可以被打开。
结合图15提供盖板4的第二种实施例，所述盖板4包括盖板本体，与盖板4的第一实施例相同，在盖板本体同一侧的两端凸起设置转动部41和操作部42，其中转动部41与盖板4的第一实施例相同，背对操作部42以及转动部42一侧的盖板本体为平面区45，限位部46由平面区45的一端形成，与盖板4的第一实施例所不同的是，在操作部42与转动部41之间不再设置加强部44，本实施例的操作部42为弧形凸台，弧形凸台的凹面作为操作面421朝向转动部41，弧形凸台的弧形外侧壁作为推动面422，也就是背对凹面的一侧作为推动面422并设有防滑凸棱；在操作部42设有与第一实施例相同的联动孔47。
结合图16提供盖板4的第三种实施例，所述盖板4包括盖板本体，在盖板本体同一侧的两端设置转动部41和操作部42，在转动部41与操作部42之间也设置有加强部44，本实施例的操作部42为宽度相同的环形凸台，也就是操作部42的推动面422处的宽度与操作部42靠近转动部41一侧的宽度相同，也可以 理解为，整个操作部42的宽度近似于操作端11端面的宽度，利于提高操作部42的机械强度，盖板4的其他结构与盖板4的第一实施例相同，也就是转动部41、安装槽411、限位部46以及平面区45均与第一实施例的结构相同。
结合图17提供盖板4的第四种实施例，所述盖板4包括盖板本体，在盖板本体同一侧的两端设置转动部41和操作部42，与第二实施例相同，在转动部41与操作部42之间不设置加强部44，本实施例的操作部42为宽度相同的平面凸台，平面凸台可以与盖板本体之间形成一定夹角，由平面凸台与盖板本体形成夹角的侧壁作为操作面421，在本实施例中，平面凸台与盖板本体相互垂直，由平面凸台与盖板本体相垂直的一侧侧壁作为操作面421。
需要说明的是，作为其它实施例，外壳1的操作端11端面也可以不设置容纳槽14，此时盖板4与外壳1转动连接，可以是可拆卸的转动连接，此时，上述实施例的盖板4转动连接在手柄机构2一侧的外壳1，也就是转动部41与手柄机构2一侧的外壳1转动连接，操作端11端面设置供第二驱动部43伸入外壳1内的通孔。其中操作部42优选凸出设置于盖板4背对操作端11端面的一侧，盖板4转动到回收位置时使盖板4可以平行贴合于操作端11端面，以减少盖板4所占据的空间；若操作部42仍凸出设置于盖板4面向操作端11端面的一侧，在盖板4平行于操作端11端面时，在盖板4与操作端11端面之间留有一定的间距，或者，由盖板4远离操作部42的一端与操作端11端面贴合，在盖板4平行于操作端11端面时，操作部42位于操作端11端面之外，避让操作端11端面。
参见图5，提供插入式断路器的第二实施例，所述插入式断路器包括外壳1，在所述外壳1内设置有至少两个并列的容纳腔，在每个容纳腔内装配有一个断路器极，也就是在外壳1内设置至少一个隔板，由隔板将外壳1内的空间分隔为两个容纳腔，或者，每个断路器极包括断路器极外壳，每个断路器极外壳内的空间作为一个容纳腔，由多个断路器极外壳拼接形成外壳1；每个断路器极包括如上述插入式断路器的实施例中的操作机构7、手柄机构2以及锁定机构，相邻两个断路器极的手柄机构2联动连接，如此，多个并列的手柄机构2转动装配于外壳1的操作端11，至少在其中一个手柄机构2一侧的操作端11端面开设有一个容纳槽14，容纳槽14对应的由一个盖板4所盖合，相邻的两个盖板4的操作部42通过联动轴6联动连接。当然，优选在每个手柄机构2一侧的操作端11端面开设有一个容纳槽14，每个容纳槽14对应一个容纳腔，且每个容纳槽14分别对应的由一个盖板4所盖合，在操作部42设置有联动孔47，在联动孔47内装配有联动轴6，相邻两个盖板4可以通过联动轴6联动连接，可以同时提拉所有盖板4将断路器从机柜中拔出。

如图9所示，所述解锁件31包括第一转动臂和第二转动臂，所述第一转动臂与第二转动臂的一端连接形成转动部41，第一转动臂的另一端端部作为第一解锁部311与手柄机构2的第一驱动部21配合，在第一转动臂的中部凸出设有凸台，所述凸台作为第二解锁部312位于面向盖板4的一侧，第二转动臂的另一端端部凸出设有作为锁定部321的凸台。
在上述三个实施例中，第一解锁部311和第二解锁部312可设置为同一个解锁部，同时配合第一驱动部21和第二驱动部43。此外，本实施例中手柄机构2和/或盖板4通过解锁件31驱动锁定件32使锁定部321缩回外壳1内，作为本实施例的另一种结构，手柄机构2和/或盖板4也可以直接驱动锁定件32，所述锁定机构包括锁定件32和弹性件33，锁定件32移动设置且设有锁定部321，弹性件33驱动锁定件32移动使锁定部321伸出限位孔13，手柄机构2和/或盖板4的转动向锁定件32施加作用力，锁定件32受力移动使锁定部321缩回外壳1内时锁定机构解锁。另外，手柄机构2和/或盖板4也可以通过多个解锁件传动驱动锁定件32解锁。

另外，当第一、第二以及第三实施例的盖板4也仅用于拉拔拆卸断路器时，省略其锁定机构中的第二解锁部312即可，或者，在盖板4上不再设置第二驱动部43，或者同时不设置第二解锁部312和第二驱动部43。
