Description

一种光缆分纤装置
本申请要求于2020年2月28日提交中国国家知识产权局、申请号为202010131112.6、发明名称为“一种光缆分纤装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及光通信设备技术领域，尤其涉及一种光缆分纤装置。
背景技术
分纤箱作为光传输设备中的一个重要结构，一般挂在小区楼梯间的墙壁上或小区绿化带中或者其他地方，通常是将主光缆与分纤箱连接，实现光纤分配功能，分纤箱再通过若干个分光缆与室内的光接口连接，最终将光信号连通至各用户。
光缆分纤装置通常包括：分纤箱、盘缆架和光缆，且分纤箱、盘缆架和光缆是三个相互独立的部件，需要现场进行组装。具体组装过程为：铺设光缆；安装分纤箱和盘缆架；再将铺设好的光缆与分纤箱进行插接；最后将多余的光缆盘存在盘缆架上。
由于分纤箱、盘缆架和光缆是相互独立的，需要现场进行组装，且组装工序多，施工时间长，组装效率低下。
发明内容
本申请的实施例提供一种光缆分纤装置，主要目的是解决现有技术中光缆分纤装置收放缆效率低下、收揽效果差、组装效率低下的技术问题。
为达到上述目的，本申请的实施例采用如下技术方案：
本申请提供了一种光缆分纤装置，包括：分纤箱和收放缆结构以及连接结构，收放缆结构用于收放与分纤箱连接的光缆；
收放缆结构包括：
底座，具有盘储腔，盘储腔与底座的一个表面相贯通以形成盘储腔开口，底座上开设有与盘储腔相连通的出缆口；
转盘，配置为盘存光缆，转盘安装在盘储腔内，分纤箱设置在盘储腔开口一侧，转盘与分纤箱相对固定，转盘和分纤箱能够相对底座同步转动；
连接结构包括：
第一连接件，设置在分纤箱上；
第二连接件，设置在底座上且与第一连接件可拆卸连接。
本申请实施例提供的光缆分纤装置，通过将转盘安装在底座的盘储腔内，且转盘可以相对底座转动，又因为转盘与分纤箱相对固定。也就是说，将缠绕在转盘上的光缆的一端与分纤箱插接后，若抽拉穿过出缆口的光缆，则分纤箱和转盘同步沿第一旋转方向转动，进而实现放缆，且需要多少光缆，就抽拉多少光缆，相比现有技术，不需要手动盘绕多余的光缆，且需要将抽拉出的多余光缆进行收揽时，由于分纤箱设置在盘储腔开口的一侧，这样就可以 通过沿与第一旋转方向相反的第二旋转方向转动分纤箱，就可以实现收揽，这样就会明显的提高收放缆效率。且底座与分纤箱连接，并可以将光缆缠绕在转盘上，在具体施工时，不需要在施工现场对三者进行现场组装，提高施工效率。
另外，由于用于盘存光缆的转盘是设置在盘储腔内，在进行收揽作业时，通过盘储腔的壁面对光缆的限定，可保障盘绕至转盘上的光缆不会出现较松散现象，以提高收揽效果；同时，通过将光缆隐藏在盘储腔内，以对光缆起到保护作用，还可以提高外形美观度。
另外，底座与分纤箱通过相配合的第一连接件和第二连接件可拆卸连接，当不需要抽拉光缆时，通过第一连接件和第二连接件将分纤箱与底座连接，以保障整个结构的整体性；当需要抽拉光缆时，通过将第一连接件和第二连接件拆开以将分纤箱与底座分离，以使分纤箱和转盘可以同步相对底座转动。
在可能的实现方式中，第一连接件和第二连接件中的其中一个为卡扣，另一个为卡槽。利用卡接结构连接分纤箱和底座，操作方便，且卡扣与卡槽形成的卡接结构，结构简单，实施方便。
在可能的实现方式中，连接结构为插接结构，该第一连接件包括连接销和开设在分纤箱上的第一插孔，第二连接件包括开设在底座上的第二插孔，连接销穿在第一插孔内和第二插孔内，且连接销与第一插孔和第二插孔均为间隙配合。
在可能的实现方式中，转盘和分纤箱能够相对底座在第一位置和第二位置之间同步移动，转盘和分纤箱的移动方向与转盘的旋转轴线的方向一致，转盘和分纤箱移动至第一位置时，转盘位于盘储腔，转盘和分纤箱移动至第二位置时，转盘位于盘储腔的外部。由于缠绕在转盘上的光缆设置在盘储腔内，这样在安装或维护光缆时操作比较困难，但是通过将转盘和分纤箱相对底座在第一位置和第二位置之间同步移动，当需要在转盘上缠绕光缆或者维护光缆时，就可以将转盘移动至第二位置，以使转盘从盘储腔内移动至盘储腔的外部，这样便于操作，提高了整个光缆分纤装置的使用性能。
在可能的实现方式中，转盘通过伸缩结构与底座连接，在伸缩结构处于伸长状态时，转盘和分纤箱处于第二位置，在伸缩结构处于收缩状态时，转盘和分纤箱处于第一位置。例如，采用伸缩气缸或伸缩油缸，即通过伸缩气缸和伸缩油缸带动转盘和分纤箱在第一位置和第二位置运动。
在可能的实现方式中，转盘通过直线电机与底座连接。即通过直线电机带动转盘和分纤箱在第一位置和第二位置运动。
在可能的实现方式中，盘储腔内设置有固定轴，固定轴与底座相对固定，固定轴的轴线与转盘的旋转轴线共线，转盘具有插孔，转盘通过插孔套设在固定轴外，转盘和分纤箱能够绕固定轴的轴线转动，且能够沿固定轴的轴线在第一位置和第二位置之间滑动；在转盘和分纤箱滑动至第一位置时，转盘与盘储腔的底部抵接；收放缆结构还包括：限位件，限位件适于转盘和分纤箱滑动至第二位置时，以阻止转盘脱离固定轴和阻止转盘朝靠近第一位置的方向移动。将转盘滑动设置在固定轴上，具体实施时，通过推拉力带动转盘和分纤箱相对固定轴移动，并采用限位件阻止转盘不能滑出固定轴和阻止转盘不能朝第二位置滑动，同时，利用转盘滑动至第一位置时，与底座抵接，以阻止转盘和分纤箱不能再继续朝远离第二位置的方向滑动。
在可能的实现方式中，限位件包括：第一凸台，第一凸台设置在固定轴的外壁面上，且靠近盘储腔开口的一端，第一凸台沿固定轴的周向设置；插孔的壁面上具有朝固定轴方向延 伸的延伸部，延伸部沿转盘的周向布设，延伸部具有弹性，延伸部靠近盘储腔底部，延伸部上开设有供第一凸台卡入的卡槽，卡槽的槽口朝向固定轴；在第一凸台卡入卡槽内时能够阻止转盘脱离固定轴和阻止转盘朝靠近第一位置的方向移动。利用第一凸台和卡槽相配合限定转盘的位置，该限位件的结构简单，实施也方便。
在可能的实现方式中，收放缆结构还包括锁紧件，锁紧件能够在锁紧状态和解锁状态之间切换；锁紧件处于锁紧状态时能够阻止位于第一位置的转盘和分纤箱朝第二位置移动，锁紧件处于解锁状态时能够允许位于第一位置的转盘和分纤箱朝第二位置移动。当底座与分纤箱通过连接结构可拆卸连接时，若分纤箱与底座分离，通过设置锁紧件保障转盘不会由第一位置朝第二位置滑动，这样就可使该光缆分纤装置根据使用情况选择转盘是在第一位置转动，还是在第二位置转动。
在可能的实现方式中，锁紧件包括：第二凸台，第二凸台设置在固定轴的外壁面上，且靠近盘储腔开口的一端，第二凸台沿固定轴的周向间隔设置，每相邻的两个第二凸台之间形成凹槽；凸筋，凸筋设置在转盘的插孔的壁面上，且凸筋沿转盘的周向间隔布设；凸筋与第二凸台相抵接时处于锁紧状态，以阻止转盘沿固定轴的轴向朝第二位置滑动；凸筋与凹槽相对时处于解锁状态，转盘能够沿固定轴的轴向朝第二位置滑动。通过沿固定轴的周向间隔布设的第二凸台和沿转盘的周向间隔布设的凸筋，阻止在第一位置的转盘滑向第二位置的基础上，还可以使转盘沿着固定轴的周向转动，采用相配合第二凸台和凸筋作为锁紧件，结构简单，制造也方便。
在可能的实现方式中，凸筋延伸至转盘的靠近盘储腔底部的一端，且凸筋的靠近盘储腔底部的一端具有供第二凸台穿过的避让槽，且避让槽沿转盘的周向开设。若需要位于第二位置的转盘转动时，转盘上的凸筋会与第二凸台干涉，进而转盘无法转动，但是若在凸筋上开设避让槽，将转盘转动时，第二凸台就可穿过避让槽，这样就可使转盘转动。
在可能的实现方式中，转盘包括相对的第一挡板和第二挡板，且第一挡板与第二挡板通过连接柱连接，插孔开设在连接柱上，连接柱通过插孔套设在固定轴外，连接柱能够绕固定轴的轴线转动，且连接柱能够沿固定轴的轴向滑动。具体实施时，光缆可以缠绕在连接柱上，第一挡板和第二挡板能够对光缆具有限位作用，以保障缠绕在连接柱上的光缆不会滑脱连接柱。
在可能的实现方式中，光缆分纤装置还包括：光缆，光缆缠绕在转盘上，光缆的一端与分纤箱的插接端连接，以将光缆上的光信号传输至分纤箱，光缆的另一端能够穿过出缆口。由于该光缆分纤装置还包括缠绕在转盘上的光缆，以实现光缆、分纤箱和收放缆结构集成为一个结构，这样会进一步提高施工效率。
在可能的实现方式中，分纤箱上设置有导向结构，导向结构用于引导光缆与分纤箱上的插接口连接。通过设置导向结构，以使光缆与分纤箱的插接口连接。
在可能的实现方式中，导向结构包括导向槽。采用导向槽作为导向结构，结构简单，便于实施。

具体实施方式
本申请实施例涉及光缆分纤装置，下面结合附图对光缆分纤装置进行详细描述。
参照图1、图2和图3，该光缆分纤装置包括分纤箱2和收放缆结构1以及连接结构3，收放缆结构2用于收放与分纤箱2连接的光缆，该收放缆结构1包括底座101和转盘102，底座101具有盘储腔103，盘储腔103与底座101的一个表面相贯通以形成盘储腔开口，底座101上开设有与盘储腔103相连通的出缆口105，转盘102配置为盘存光缆，转盘102安装在盘存腔103内，分纤箱2设置在盘储腔开口一侧，转盘102与分纤箱2相对固定，转盘102和分纤箱2能够相对底座101同步转动，连接结构3包括：设置在分纤箱2上的第一连接件302，以及设置在底座101上且与第一连接件302可拆卸连接的第二连接件301。
具体实施时，光缆缠绕在转盘102上，光缆的一端与分纤箱2插接，以将光信号传输至分纤2，再通过分纤箱2实现光信号的分配。
由于光缆缠绕在转盘上，抽拉穿过出缆口105的光缆的端部(该端部指是光缆的不与分纤箱插接的一端)，转盘102和分纤箱2就会相对底座101沿第一旋转方向转动，以实现放缆，且需要铺设多少光缆，就抽拉多少光缆，相比现有技术，不需要手工盘绕抽拉出的多余光缆。另外，即使抽拉的光缆过多，将分纤箱2和转盘102沿与第一旋转方向相反的第二旋转方向转动，就会实现收揽。所以，采用本申请实施例提供的光缆分纤装置可有效提高收放缆的施工效率。
因为分纤箱2与转盘102相对固定，即分纤箱2会与转动的转盘102同步相对底座101转动，这样就不会造成与分纤箱插接的且缠绕在转盘上的光缆发生扭曲，甚至与其他结构发生干涉的现象。
由于转盘102安装在盘储腔103内，这样在收揽时，回收的光缆通过盘储腔103的壁面的限定，不会导致缠绕在转盘上后出现较松散的现象，这样就相对应的提高了收揽效果。同时，由于该收放缆结构一般设置在室外的较恶劣的环境下，相比光缆外露，将光缆隐藏在盘储腔内，会对光缆起到保护作用，也可提高收放缆结构的外形美观度；通过将转盘102设置在盘储腔103内，还可以减小收放缆结构的如图3所示的沿H方向的尺寸。
另外，可根据施工现场需要的不同的光缆长度和不同的分纤容量，收放缆结构和分纤箱可以在施工现场组装。当然，也可以将收放缆结构和分纤箱在运输至施工现场前组装好，以便提高施工效率。
具体实施时，可以根据光缆的长度和光缆的接头数量(即光缆的直径)设计盘储腔的高度尺寸，以保障光缆位于盘储腔内。
转盘102与底座101转动连接的结构具有多种情况，下述通过两种实施例进行解释说明。
实施例一，参照图3，盘储腔103内设置有固定轴104，固定轴104的轴线与转盘102的旋转轴线共线，转盘102具有插孔，转盘102通过插孔套设在固定轴104外，且能够绕固定轴104的轴线转动。通过将转盘转动套设在固定轴外，以实现转盘和分纤箱相对底座的转动。
具体实施时，固定轴104可以与底座101成一体结构设计，也可以通过连接件将固定轴104固定在底座101上。
实施例二，盘储腔103的壁面具有沿其周向设置的旋转轨道，转盘和分纤箱可以沿着该旋转轨道相对底座进行旋转。
另外，转盘与底座转动连接的结构还可以为其他结构，在此不再穷举。
上述的实施例一和实施例二的转动连接方式的结构均比较简单，但是，实施例一相比实施例二，安装拆卸转盘比较方便，所以，本申请优选于采用实施例一的转动连接结构。
当转盘102套设在固定轴104外，且分纤箱2与转盘102相对固定时，为了防止分纤箱2和转盘102在绕固定轴104旋转时从固定轴104上脱出，还包括止位结构，该止位结构用于阻止分纤箱2和转盘102从固定轴104上脱出。例如，参照图4，分纤箱2和转盘102通过连接件(包括螺栓502或者铆钉或者其他连接件)与固定轴104连接，固定轴104上开设有供连接件穿过的穿孔，分纤箱2上具有用于锁止螺栓502的螺母501。为了实现分纤箱2和转盘102可以相对固定轴104转动，连接件套设在套筒503内，且套筒503套设在穿孔内且能够相对固定轴转动。这样就可以通过螺栓和螺母的止位，保障转盘不会从固定轴104上脱出。当然，止位结构也可以为其他结构，任何结构均在本申请的保护范围之内。
参照图1和图2，底座101通过连接结构3与分纤箱2可拆卸连接。
当不需要抽拉光缆时，通过连接结构将分纤箱与底座连接，以保障整个结构的整体性，当需要抽拉光缆时，利用连接结构将分纤箱与底座分离，以使分纤箱和转盘可以同步转动。
实现分纤箱与底座可拆卸连接的连接结构3的结构具有多种情况，下述通过两种实施例进行描述。
实施例一，连接结构为插接结构。
例如，第一连接件包括连接销和开设在分纤箱上的第一插孔，第二连接件包括开设在底 座上的第二插孔，连接销穿在第一插孔内和第二插孔内，且连接销与第一插孔和第二插孔均为间隙配合。即需要将分纤箱与底座固定时，连接销依次穿过第一插孔和第二插孔；需要分纤箱与底座分离时，连接销从第一插孔和第二插孔拔出。
实施例二，连接结构为卡接结构。
卡接结构具有多种可实施的结构，示例的，参照图3，连接结构包括：为第一连接件的卡扣，和为第二连接件的卡槽，卡扣设置在底座101上，则卡槽开设在分纤箱2上。再示例的，卡扣设置在分纤箱上，则卡槽开设在底座上。
因为卡接结构操作简单，可提高拆装的方便性，所以，本申请优选于采用卡接结构。
通过卡接结构连接底座和分纤箱时，该收放缆结构的工作过程为：当需要放缆时，卡扣从卡槽内移出，抽拉穿过出缆口的光缆的端部，分纤箱2和转盘102就会相对底座101沿第一旋转方向同步转动，进而实现放缆。当抽拉的光缆过多时，通过使分纤箱2沿与第一旋转反向相反的反向转动，就会带动转盘102同步转动，以将多余的光缆缠绕在转盘上。
为了提高该卡扣的使用性能，参照图5和图6，卡扣通过转轴303与底座101转动连接。即通过转轴303将卡扣与底座连接，相比卡扣通过柔性材料的结构与底座连接，提高卡扣的使用寿命。
由于转盘102转动设置在盘储腔103内(如图2所示)，当需要在转盘102上安装光缆或者拆卸光缆时，操作空间有限，这样就会给施工造成不便，或者，当需要对缠绕在转盘102上的光缆进行维护时，依然会给施工造成不便。
为了提高施工的方便性，参照图7和图11，转盘102和分纤箱2能够相对底座101在第一位置和第二位置之间同步移动，转盘102和分纤箱2的移动方向与转盘102的旋转轴线的方向一致，参照图7，转盘102和分纤箱2移动至第一位置时，转盘102位于盘储腔103内，参照图11，转盘102和分纤箱2移动至第二位置时，转盘102位于盘储腔103的外部。
也就是说，转盘102和分纤箱2可以在第一位置和第二位置之间移动，当转盘102移动至第二位置时，转盘102位于盘储腔103的外部，这样就可以方便进行光缆的安装、拆卸或者维护等作业，以提高该收放缆结构的使用性能。
实现转盘102和分纤箱2相对底座101在第一位置和第二位置之间同步移动的结构具有多种，下述通过两种实施例进行说明。
实施例一，转盘102通过伸缩结构与底座101连接，在伸缩结构处于伸长状态时，转盘和分纤箱处于第二位置，在伸缩结构处于收缩状态时，转盘和分纤箱处于第一位置。即通过伸缩结构的伸缩，带动转盘和分纤箱在第一位置和第二位置之间同步移动。
伸缩结构可以采用伸缩气缸或者伸缩油缸，通过伸缩气缸的伸缩驱动转盘和分纤箱在第一位置和第二位置之间移动。具体的，通过控制伸缩气缸或伸缩油缸的行程以保障转盘和分纤箱在第一位置和第二位置之间移动。
另外，也可以采用直线电机驱动转盘和分纤箱在第一位置和第二位置之间移动。
实施例二，转盘102能够沿固定轴104的轴线在第一位置和第二位置之间滑动。为了保障转盘能够在第一位置和第二位置之间滑动，转盘和分纤箱滑动至第一位置时，转盘102与盘储腔103的底部抵接；收放缆结构还包括：限位件，限位件适于转盘102和分纤箱2滑动至第二位置时，以阻止转盘102脱离固定轴104和阻止转盘102朝靠近第一位置的方向移动。
具体实施时，通过对转盘和分纤箱施加拉力，就可使转盘102沿固定轴104的轴向滑动，当转盘由第一位置朝第二位置滑动时，通过限位件的限定，以使转盘102处于第二位置，既 不能脱离固定轴也不会朝第一位置移动；当转盘由第二位置朝第一位置滑动时，转盘102就会与盘储腔103的底部接触，这样就阻止转盘102继续移动。
限位件具有多种可实施的结构，下面通过三种实施例进行解释说明。
实施例一，参照图11，固定轴104的外壁面上设置有第一凸台1041，且靠近盘储腔开口的一端，第一凸台1041沿固定轴104的周向设置；插孔的壁面上具有朝固定轴104方向延伸的延伸部1022，延伸部1022沿转盘102的周向布设，延伸部1022具有弹性，延伸部1022靠近盘储腔底部，延伸部1022上开设有供第一凸台1041卡入的卡槽，卡槽的槽口朝向固定轴，在第一凸台1041卡入卡槽内时能够阻止转盘102脱离固定轴104和阻止转盘102朝靠近第一位置的方向移动。
实施例二，参照图14，固定轴104的靠近盘储腔开口的一端具有第一导槽601，第一导槽601沿固定轴104的周向设置，参照图15，当转盘102滑动至第二位置时，穿过转盘的侧面的连接销7插入第一导槽601。即通过连接销7将转盘102与固定轴104连接，以阻止转盘102脱离固定轴和朝第一位置的方向滑动。另外，由于第一导槽601沿固定轴的周向设置，在保障转盘不能朝第二位置滑动和脱离固定轴的基础上，还不会影响转盘的转动。
实施例三，转盘102通过压缩弹簧与固定轴104连接，压缩弹簧的一端与固定轴连接，另一端与转盘102连接。当转盘处于第一位置时，压缩弹簧处于压缩状态，当转盘处于第二位置时，压缩弹簧处于自由状态，即转盘处于第二位置时，通过压缩弹簧对转盘的牵拉，以使转盘即不会脱离固定轴，也不会朝第一位置移动。此结构中，压缩弹簧的弹性变形量等于第一位置与第二位置之间的距离，这样就可保障转盘在第一位置和第二位置之间移动。
由于实施例一相比实施例二和实施例三，结构简单，便于实施，且设置在转盘与固定轴之间，即隐藏在收放缆结构的内部，不外露，提高收放缆结构的外形美观度。所以，本申请优选于实施例一的限位件。
当底座与分纤箱通过连接结构可拆卸连接时，若连接结构处于打开状态时，分纤箱与底座分离，转盘和分纤箱就有可能沿着固定轴滑动至第二位置。
为了保障在需要时，转盘和分纤箱才滑动至第二位置时，该收放缆结构包括锁紧件，锁紧件能够在锁紧状态和解锁状态之间切换；锁紧件处于锁紧状态时能够阻止位于第一位置的转盘朝第二位置移动，锁紧件处于解锁状态时能够允许位于第一位置的转盘朝第二位置移动。
锁紧件具有多种可实施的结构，下述通过两种实施例进行解释。
实施例一，参照图7和图8，固定轴104的外壁面上设置第二凸台，且靠近盘储腔开口的一端，第二凸台沿固定轴的周向间隔设置，每相邻的两个第二凸台之间形成凹槽1042，参照图7和图9，转盘102的插孔的壁面上设置凸筋1021，且凸筋1021沿转盘102的周向间隔布设；凸筋1021与第二凸台相抵接时处于锁紧状态，以阻止转盘沿固定轴的轴向朝第二位置滑动；凸筋1021与凹槽相对时处于解锁状态，转盘能够沿固定轴的轴向朝第二位置滑动。
通过沿固定轴的周向间隔布设的第二凸台和沿转盘的周向间隔布设的凸筋，阻止在第一位置的转盘滑向第二位置的基础上，还可以使转盘沿着固定轴的周向转动，采用相配合第二凸台和凸筋作为锁紧件，结构简单，制造也方便。
具体实施时，当需要将该锁紧件处于锁紧状态时，通过旋转转盘，以使凸筋1021与第二凸台抵接；当需要沿固定轴移动转盘时，旋转转盘，以使凸筋与凹槽相对。
实施例二，参照图14，固定轴104的靠近盘储腔底部的一端具有第二导向槽602，第二导槽602沿固定轴的周向设置，当转盘102滑动至第一位置时，穿过转盘的侧面的连接销7 插入第二导槽602。即通过连接销7将转盘102与固定轴104连接，即处于锁紧状态，当将连接销7从第二导向槽602拔出，即处于解锁状态，这样转盘就可以沿固定轴朝第二位置移动。
当采用实施例二的锁紧件时，由于转盘在第一位置时是处于盘储腔内的，插拔连接销7是很不方便的，所以，本申请优选于实施例一所示的锁紧件。
另外，采用实施例一的锁紧件还可以达到下述技术效果：为了提高整个光缆分纤装置的外形美观度，通常是将分纤箱的外轮廓与底座的外轮廓相同(如图1所示)，这样的话，分纤箱2就会将开设在底座101上的安装孔106遮盖住(如图16所示)，当需要通过穿过安装孔106的连接件将该收放缆结构安装在墙面上时，先将转盘和分纤箱相对底座旋转，以使安装孔外露，进而就能将该光缆分纤装置安装在墙面上了。所以，该种结构锁紧件在实现整个光缆分纤装置外形美观的情况下，实现锁紧和解锁功能。
在上述限位件的实施例一中，固定轴104的外壁面上设置有第一凸台1041，第一凸台1041靠近盘储腔开口的一端；在上述锁紧件的实施例一中，固定轴104的外壁面上设置第二凸台，第二凸台靠近盘储腔开口的一端。为了简化结构，第一凸台和第二凸台可以是一个凸台，且该凸台沿固定轴的周向间隔设置。这样该凸台与延伸部相配合时能够对转盘起到限位作用，与凸筋相配合时起到锁紧作用。
为了实现转盘102处于第二位置时，转盘102依然可以相对固定轴104转动，参照图12和图13，凸筋1021延伸至转盘102的靠近底座101底部的一端，凸筋1021的靠近底座底部的一端具有供第二凸台穿过的避让槽1023，且避让槽1023沿转盘102的周向开设；参照图13，随转盘转动的凸筋就不会受到第二凸台1041的干涉，通过在凸筋1021上开设避让槽1023，将转盘转动时，第二凸台就可穿过避让槽，这样就可使转盘转动。
转盘的结构具有多种情况，示例的，参照图11，转盘包括相对的第一挡板801和第二挡板802，且第一挡板801与第二挡板802通过连接柱803连接，插孔开设在连接柱803上，连接柱803通过插孔套设在固定轴外，连接柱803能够相对固定轴转动，且能够沿固定轴的轴向滑动。再示例的，转盘包括转柱，转柱转动套设在固定轴外且能够沿固定轴的轴向滑动。
上述关于转盘的第一个实施例相比第二个实施例，光缆缠绕在连接柱的外部，通过第一挡板和第二挡板的止位，防止光缆沿连接柱的轴向发生移动。所以，本申请优选于采用第一个实施例的转盘结构。当然，转盘也可以为其他结构，任何结构的转盘均在本申请的保护范围之内。
具体实施时，由于分纤箱与转盘相对固定，即与底座可以同步转动，这样可以根据使用需求，以使出缆口朝向所需的方向，同理，分纤箱的插接端也可以朝向所需的方向。
为了增加底座101的强度，参照图16，底座101的周向设置有加强筋107。即通过四周设置的加强筋107增加该底座的强度。另外，参照图10，若需要将转盘需要将转盘相对固定轴旋转α后，才可使转盘沿固定轴的轴线滑动，将加强筋107的第一端与固定轴的轴心之间的连线为第一直线，加强筋107的第二端与固定轴的轴心之间的连线为第二直线(第一端与第二端相对)，且第一直线与第二直线之间的夹角为α，这样加强筋107就可作为指示线，以使转盘相对固定轴旋转α。例如，若需要将转盘需要将转盘相对固定轴旋转45°后，才可使转盘沿固定轴的轴线滑动，这样就可将加强筋的第一直线与第二直线之间的夹角为45°。
为了进一步提高施工效率，该光缆分纤装置还包括光缆，光缆缠绕在转盘上，光缆的一端与分纤箱的插接端连接，以将光缆上的光信号传输至分纤箱。由于该光缆分纤装置还包括 缠绕在转盘上的光缆，以实现光缆、分纤箱和收放缆结构集成为一个组件，这样会进一步提高施工效率。
当抽拉光缆时，为了避免光缆的与分纤箱插接的一端发生扭曲或者与其他结构发生干涉的现象，分纤箱上设置导向结构，该导向结构用于引导光缆与分纤箱的插接端插接。这样当抽拉光缆时，不会影响光缆的与分纤箱插接的一端，以保障光缆与分纤箱的插接性能。
参照图17，分纤箱2上设置有挡板201，该挡板201与分纤箱2的侧壁之间形成导向槽，该导向槽为导向结构，光缆沿着导向槽布设并与插接端202插接。
为了进一步提高光缆与分纤箱的插接端202的连接强度，布设在导向槽内的光缆通过卡箍与挡板固定连接，这样就会进一步防止抽拉光揽的另一端时，影响光缆与插接端的连接性。且该结构形成的导向结构，结构简单，易于实施。
具体实施时，分纤箱与转盘相对固定，且分纤箱与转盘固定连接方式具有多种可实施的结构，示例的，分纤箱与转盘通过固定件连接；再示例的，参照图18，转盘102的朝向分纤箱2的一侧设置有安装柱402，分纤箱具有插入孔403，安装柱402伸至插入孔403内，且位于插入孔403内的连接件401与安装柱402连接。
由于开设在分纤箱上的插入孔403贯穿分纤箱2的上下表面，为了防止灰尘通过插入孔403进入分纤箱2的内部，参照图18，在分纤箱2的上表面的插入孔403内设置有堵帽404。即通过堵帽404防止灰尘通过插入孔403进入分纤箱内。
在本说明书的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。
