Description

抽拉式组件、插框及光分箱
本申请要求于2017年11月06日提交中国国家知识产权局、申请号为201711077748.1、发明名称为“抽拉式组件、插框及光分箱”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
本申请涉及信号传输领域，特别涉及一种抽拉式组件、插框及光分箱。
背景技术
随着用户对带宽需求的不断增长，传统的铜线宽带接入系统越来越无法满足用户的需求，与此同时，带宽容量巨大的光纤通信技术日益成熟，应用成本逐年下降，光纤接入网成为下一代宽带接入网的有力竞争者。其中，光分配网络(Optical Distribution Network，ODN)是实现光纤入网的重要组成部分之一。
该光分配网络通常是由主干光缆、分光箱和配线光缆等组成，该分光箱中设置有多个用于连接主干光缆和配线光缆的托盘。通常情况下，为了方便维护托盘中的光缆，可以将托盘设计为能够抽拉的模块。例如，可以在分光箱内设置滑道支架，在托盘的两侧固定设置与该滑道支架配合的滑道，当需要维护托盘时，维修人员可以拉出托盘，此时该托盘可以在滑道支架上运动一段距离，以便维修人员对托盘内部进行维护，维护完成后，维修人员可以将托盘推回光分箱内。
由于在托盘内接入的光缆会经过托盘的至少一侧，如果不在该托盘的至少一侧预留冗余光缆，可能会导致无法拉出托盘，因此需要在托盘外部的至少一侧预留冗余光缆(即多设置一段长度的光缆)。此时，如果托盘维护完成后重新推回箱体内，该托盘的至少一侧的冗余光缆比较杂乱，导致后续对分光箱中的光缆进行维护时的效率较低。
发明内容
本申请提供了一种抽拉式组件、插框及光分箱，可以解决相关技术中后续对分光箱中的光缆进行维护时的效率较低的问题。所述技术方案如下：

可选的，所述托盘相对于所述滑道支架的速度与所述滑道相对于所述滑道支架的速度的比例为固定值。这样在托盘的抽拉过程中，该托盘的左右两侧受力均匀，避免了托盘中的设置的线缆受力导致阻碍该托盘的运动，进而使得该托盘可以正常抽拉，因此可以有效的提高了托盘使用的可靠性。
可选的，所述抽拉式组件还包括第一曲线引导结构，所述第一曲线引导结构固定在所述滑道前端，所述第一曲线引导结构的一端与所述滑道前端的开口连通，另一端设置有朝向所述滑道的后端的引导开口；所述托盘的后端设置有传线开口；所述传线开口、所述滑道的滑动通道以及所述第一曲线引导结构用于将所述线缆引导至所述滑道外部。这样当该抽拉式组件内设置线缆时，延伸到抽拉式组件外部的线缆走向朝向滑道的后端，可以将该延伸至抽拉式组件外部的线缆设置在抽拉式组件的两侧，进而可以减少分光箱内线缆的占用空间。

可选的，所述托盘相对于所述滑道支架的速度与所述滑道相对于所述滑道支架的速度的比例为2:1。这样当抽拉式组件内设置线缆时，可以避免在托盘抽拉过程中，滑动通道上的冗余线缆移动到抽拉式组件外时出现弯折的现象，进而可以对线缆起到保护作用。
可选的，所述第一传动部为第一齿条，所述第二传动部为齿轮组，所述第三传动部为第二齿条；所述齿轮组包括：至少一个齿轮，所述齿轮组中的每个齿轮的大小相同，且所述至少一个齿轮依次啮合；其中，所述第一齿条的长度方向与所述第二齿条的长度方向平行，所述齿轮组分别与所述第一齿条和所述第二齿条啮合。这样可以保证托盘相对于滑道支架的速度与滑道相对于滑道支架的速度的比例为2:1。

可选的，所述抽拉式组件还包括：限位机构，所述限位机构设置在所述滑道与所述滑道支架之间，用于限制所述托盘在所述滑道支架上的运动距离。这样可以防止该托盘从滑道支架中脱离，进而避免了由于托盘从滑道支架中脱离，导致出现需要反复组装抽拉式组件的问题。

可选的，所述抽拉式组件还包括：至少一个第三曲线引导结构，所述至少一个第三曲线引导结构可拆卸的设置在所述托盘内。由于该至少一个第三曲线引导结构是可拆卸的设置在托盘内的，因此可以设计不同形状的第三曲线引导结构，以使该托盘可以适配于不同类型的走线场景中。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
本申请示例性实施例提供了一种光分箱，请参考图1，图1是本申请示例性实施例提供的一种光分箱00的结构示意图，该光分箱可以包括：箱体01，该箱体内设置有插框02，该插框02内设置有多个抽拉式组件10。该抽拉式组件10内可以设置有线缆，例如，可以通过 该抽拉式组件10连接主干光缆和配线光缆。
请参考图2，图2是本申请示意性实施例提供的一种抽拉式组件的俯视图，该抽拉式组件10可以包括：托盘11、两个滑道12、两个滑道支架13和同步传动机构14，该托盘11用于设置线缆。可选的，该线缆可以为电缆或光缆，该光缆可以由一个或多个光纤组成。
其中，该两个滑道12中每个滑道12的结构可以参考图3A和图3B所示，图3A是本申请示意性实施例提供的一种滑道12的结构示意图，图3B是本申请示意性实施例提供的另一种滑道12的结构示意图，该滑道12可以包括：滑动通道121，以及位于滑动通道121相对两侧的卡接部122和承载部123，每一卡接部122分别卡接在一个滑道支架13中，承载部123用于支撑托盘11。
如图2所示，该同步传动机构14可以包括：设置在滑道支架13上的第一传动部141、设置在滑道12上的第二传动部142以及设置在托盘11上的第三传动部143。在托盘11受到外部作用(例如，该外部作用可以为对托盘11施加的拉力或者对对托盘11施加的压力)时，在第一传动部141、第二传动部142和第三传动部143的配合下，托盘11、滑道12与滑道支架13能够两两相对运动。
为了清楚的表示滑道支架与第一传动部的位置关系，以及滑道与卡接部的位置关系，请参考图4，图4是本申请示意性实施例提供的一种滑道支架13的结构示意图，同步传动机构中的第一传动部141可以设置在该滑道支架13的底部，该滑道支架13中设置有与滑道中的卡接部配合的卡接凹槽131，通过该卡接凹槽131以及滑道上的卡接部可以将滑道卡接在滑道支架13中。
同时，为了清楚的表示托盘与第三传动部的位置关系，请参考图5A，图5A是本申请示意性实施例提供的一种托盘11的底部结构示意图，同步传动机构中的第三传动部143可以设置在该托盘11的底部。
在本申请实施例中，如图2和图3B所示，当该抽拉式组件10内设置线缆时，该线缆可以通过滑动通道121延伸到抽拉式组件10外，假设该托盘11内设置的线缆为第一线缆，在托盘未拉出时，位于滑动通道121上的线缆为第二线缆，通常情况下，第一线缆固定在托盘11内，由于托盘11与滑道12之间能够相对运动，在该托盘11的拉出(也即对托盘11施加拉力)的过程中，该第二线缆在第一线缆的作用下向抽拉式组件10外移动；在该托盘11的推回(也即对托盘11施加压力)的过程中，该第二线缆在第一线缆的作用下向抽拉式组件10内移动，在该托盘11推回后，第二线缆重新位于滑动通道121上，该第二线缆相当于冗余线缆，因此在托盘11未拉出的状态下，该冗余线缆位于抽拉式组件10内，进而有效的避免了冗余线缆在抽拉式组件外出现杂乱的情况，从而有效的提高了后续对分光箱中的线缆进行维护时的效率。又由于滑道12与滑道支架13之间能够相对运动，因此该抽拉式组件10中的托盘11可以拉出，便于后续维护。
可选的，如图2所示，在托盘11受到外部作用时，该抽拉式组件10中托盘11相对于滑道支架13的速度与滑道12相对于滑道支架13的速度的比例为固定值，此时，在托盘11的抽拉(也即托盘11的拉出或者推回)过程中，该托盘11的左右两侧受力均匀，避免了托盘11中的设置的线缆受力导致阻碍该托盘11的运动，进而使得该托盘11可以正常抽拉，因此可以有效的提高了托盘11使用的可靠性。例如，托盘11相对于滑道支架13的速度与滑道 12相对于滑道支架13的速度的比例可以为2.1:1、2.2:1或2:1等。该固定比值可以根据具体抽拉情况设置，只要保证托盘11能够完全拉出即可，本申请实施例对此不做限定。
在本申请实施例中，如图2所示，该抽拉式组件10还可以包括：第一曲线引导结构15，该第一曲线引导结构15固定在滑道12的前端(即图2所示的右端)，为了更清楚的看出第一曲线结构15与滑道12的位置关系，请参考图3B，该第一曲线引导结构15的一端与滑道12前端的开口124连通，另一端设置有朝向滑道12的后端(即图2所示的左端)的引导开口151。请参考图5B，图5B是本申请示意性实施例提供的一种托盘11的正面结构示意图，该托盘11的后端设置有传线开口111，当抽拉式组件10内设置线缆时，依次通过传线开口111、滑道12的滑动通道121以及第一曲线引导结构15可以将线缆引导至滑道12外部，也即将线缆引导至抽拉式组件10外，此时，延伸到抽拉式组件10外部的线缆走向朝向滑道12的后端，可以将该延伸至抽拉式组件10外部的线缆设置在抽拉式组件10的两侧，进而可以减少分光箱内线缆的占用空间。
实际应用中，该第一曲线引导结构上可以设置有端盖结构，该端盖结构可以与第一曲线引导结构可拆卸连接，当抽拉式组件设置线缆时，该端盖结构可以从第一曲线引导结构上拆卸下来，在线缆经过该第一曲线引导结构后，可以再将端盖结构设置在第一曲线引导结构上，进而可以简化线缆的安装过程。在本申请实施例中，该端盖结构还可以与第一曲线移动结构活动连接，示例的，如图3A或图3B所示，该端盖结构152可以包括：端盖152a、端盖转轴152b和端盖卡扣152c，该端盖152a可以通过端盖转轴152b与第一曲线引导结构15活动连接，该端盖152a可以通过端盖卡扣152c卡接在第一曲线引导结构15上，当抽拉式组件内设置线缆时，可以按压端盖卡扣152c使得端盖152a与第一曲线引导结构15的卡接关系解除，此时，端盖152a可以绕端盖转轴152b转动，在线缆经过该第一曲线引导结构后，可以再通过端盖卡扣152c将端盖152a卡接在第一曲线引导结构15上。
示例的，请参考图6A，图6A是本申请示意性实施例提供的一种抽拉式组件中设置线缆且处于未拉出状态的效果图，假设位于滑道12的滑动通道上的线缆为第二线缆b，位于抽拉式组件10外的线缆为第三线缆c，由于设置了第一曲线引导结构15，该第三线缆c可以位于抽拉式组件10的两侧，当该抽拉式组件处于拉出状态时，请参考图6B，图6B是本申请示意性实施例提供的一种抽拉式组件中设置线缆且处于拉出状态的效果图，在托盘11拉出后，第二线缆b移动到滑道12外部，且第二线缆b同要位于抽拉式组件10的两侧。需要说明的是，该图6A与图6B中仅示出了抽拉式组件中的托盘11与滑道12的结构，滑道支架的结构未示出，并且由于该抽拉式组件10两侧的滑道12是对称设置的，位于两个滑道12中线缆的受力以及运动方式相同，因此6A和图6B仅示出了线缆经过一个滑道的情况，对于线缆经过另一滑道的情况可以参考上述实施例中的对应部分，本申请实施例对此不再赘述。
实际应用中，如图6B所示，第三线缆c通常固定在抽拉式组件10的两侧，通常情况下，在托盘11拉出后，第二线缆b处于伸直状态，在第二线缆b向滑道12外移动的过程中，该第二线缆b在第三线缆c的作用下可能出现弯折的现象，也即是，该第三线缆c会对第二线缆b产生多余的压力，进而可能会损伤第二线缆b。为了避免损伤第二线缆b，需要在第二线缆b的移动过程中，始终保证位于滑道12外的第二线缆b处于伸直状态。示例的，若位于滑道12外的第二线缆b始终处于伸直状态，则在第二线缆b的移动过程中，该第一曲线引导结构15也需要沿着托盘11的运动方向x移动，此时，第一曲线引导结构15相当于动滑轮， 根据动滑轮的运动速度关系可知，该第一曲线引导结构15沿托盘11的运动方向x移动的速度与第二线缆b的移动速度的比例关系为1:2，因此该第一曲线引导结构15可以为半圆形引导槽，该半圆形引导槽的延伸方向与滑道12的滑动通道的延伸方向相切，并且需要保证托盘11相对于滑道支架的速度与滑道12相对于滑道支架的速度的比例为2:1。
可选的，请参考图2、图3和图5A，同步传动组件14中的第一传动部141可以为第一齿条，第二传动部142可以为齿轮组，第三传动部142可以为第二齿条，其中，该第一齿条的长度方向与第二齿条的长度方向可以平行，齿轮组分别与第一齿条和第二齿条啮合。该齿轮组可以包括：至少一个齿轮，该至少一个齿轮依次啮合，齿轮组中的每个齿轮的大小相同，也即是，每个齿轮的直径相同，且每个齿轮的齿数相同。可选的，该齿轮组中齿轮的个数为奇数，进而可以保证滑道12的运动方向与托盘11的运动方向相同。当该该轮组包含一个齿轮时，请参考图7，图7是本申请示意性实施例提供的一种抽拉式组件受到外部作用时托盘运动的简易图，假设滑道12相对于滑道支架13的运动的速度V1满足：V1＝v，由于齿轮(也即第二传动部142)是固定在滑道12上的，因此该齿轮相对于滑道支架13的运动的速度V2也为v，即V2满足：V2＝v；根据齿轮与齿条的运动速度关系可知，托盘11相对于滑道支架13的运动的速度V3满足：V3＝2v，此时托盘11相对于滑道支架13的速度与滑道12相对于滑道支架的速度的比例为2:1。
需要说明的是，图2是以齿轮组中包括3个齿轮为例进行示意性说明的，由于该3个齿轮的大小相同，因此该3个齿轮在传动过程中每个齿轮的传动速度相同，该3个齿轮的传动效果与1个齿轮的传动效果相同。进一步的，只需要保证齿轮组中每个齿轮的大小相同，且该齿轮组中齿轮的个数为奇数，便可以保证托盘相对于滑道支架的速度与滑道相对于滑道支架的速度的比例为2:1。
在本申请实施例中，齿轮组在第一齿条上的可移动距离，和齿轮组与第二齿条上的可移动运动距离相等，且均大于预设距离阈值，进而可以保证该托盘可以全部拉出，方便对托盘内部进行维护。可选的，该预设距离阈值小于或等于轨道长度的二分之一。
可选的，该抽拉式组件还可以包括：锁紧机构，该锁紧机构用于托盘处于未拉出状态时，在滑道支架上锁紧托盘，进而可以有效防止在托盘处于未拉出状态时，由于外界因素导致该托盘在滑道支架上移动。示例的，请参考图3A、图3B和图5A，该锁紧机构16可以包括：设置在托盘11上的弹性按钮161，以及设置在滑道12上与弹性按钮161配合的凹槽162，该弹性按钮161可以包括：弹性片161a和设置在该弹性片161a上的钩状凸起结构161b。当托盘11处于未拉出状态时，该钩状凸起结构161b可以卡接在凹槽162内，进而限制了托盘11在滑道12上的运动，当该托盘11无法在滑道12上运动时，在齿轮组的作用下，滑道12也无法在滑道支架上运动，因此可以在滑道支架上锁紧托盘11；当需要拉出托盘11时，可以拨动弹性片161a，使得钩状凸起结构161与凹槽162的卡接关系解除，进而使得该托盘11可以在滑道上运动，从而可以将托盘11从滑道支架中拉出。
可选的，该抽拉式组件还可以包括：限位机构，该限位机构设置在滑道与滑道支架之间，用于限制托盘在滑道支架上的运动距离，可以防止该托盘从滑道支架中脱离，进而避免了由于托盘从滑道支架中脱离，导致出现需要反复组装抽拉式组件的问题。示例的，请参考图3A和图4，该限位机构17可以包括：设置在滑道12且靠近滑道支架的一侧上的台阶结构171(也即该台阶结构171设置在卡接部122上)，以及设置在滑道支架13的一端的凸起结构 172，当滑道12在运动至指定位置时，该台阶结构171可以与凸起结构172卡接，进而可以有的防止托盘从滑道支架13中脱离。
在本申请实施例中，该限位机构17还可以包括：与台阶结构171通过转轴173连接的活动臂174，该活动臂174在受到外力作用时能够带动台阶结构171绕转轴173转动，以解除台阶结构171与凸起结构172的卡接关系。实际应用中，该活动臂174与台阶结构171为一体结构，通过转轴173可以将该台阶结构171与活动臂174固定在卡接部122上，在该台阶结构171与凸起结构172卡接后，若在该活动臂174远离转轴173的一端上接收到沿方向y的外力时，该活动臂174可以绕转轴173转动，进而可以解除台阶结构171与凸起结构172的卡接关系，使得托盘可以从滑动支架13中脱离，从而可以对该托盘整体进行维护。
可选的，如图5B所示，该抽拉式组件还可以包括：至少一个第三曲线移动结构18，该至少一个第三曲线引导结构18可拆卸的设置在托盘11内，该托盘11还可以包括：直线形引导结构112，每个第三曲线引导结构18可以为圆弧形引导槽，该圆弧形引导槽的延伸方向与直线形引导结构121的延伸方向相切。在本申请实施例中，该托盘11内还可以包括：第二曲线引导结构113，该第二曲线引导结构113设置在传线开口111处，该第二曲线引导结构113可以为圆柱状结构，该圆柱状结构的外壁与滑道的延伸方向相切。当抽拉式组件内设置线缆时，托盘11内的线缆可以预先分为至少一束线缆，该至少一束线缆可以与至少一个第三曲线引导结构18一一对应，每一束线缆经过对应的第三曲线引导结构18后，汇聚到直线形引导结构122中，再经过第二曲线引导结构113，可以将托盘11内设置的线缆引导至滑道的滑道通道中。实际应用中，由于该至少一个第三曲线引导结构18是可拆卸的设置在托盘11内的，因此可以设计不同形状的第三曲线引导结构18，以使该托盘11可以适配于不同类型的走线场景中。
在本申请实施例中，当抽拉式组件内设置线缆时，线缆在抽拉式组件内不可避免的需要弯折，通常情况下，可以在抽拉式组件内设置曲线引导结构(例如，第一曲线引导结构、第二曲线引导结构和第三曲线引导结构)，抽拉式组件内设置的线缆可以通过该曲线引导结构进行弯折，为了避免线缆由于过度弯折导致线缆出现损坏的现象，该抽拉式组件中的每个曲线引导结构的最小半径均大于或等于预设的极限弯折尺寸，该极限弯折尺寸可以为30毫米。
可选的，如图5B所示，该抽拉式组件还可以包括：适配器固定部19，该适配器固定部19可拆卸的设置在托盘11内，该适配器固定部19用于固定线缆的适配器20。实际应用中，当抽拉式组件内设置线缆时，该适配器20可以对线缆进行转接，例如，若线缆为主干光缆和配线光缆，该主干光缆和配线光缆均可以连接适配器，进而可以通过该抽拉式组件实现了主干光缆和配线光缆的连接；该适配器20还可以将线缆固定在托盘11内。
在本申请实施例中，如图5B所示，该托盘11可以为对称结构，该适配器固定部19设置在托盘的对称轴L处，且适配器固定部19的长度方向与托盘11的运动方向x平行。为了清楚的表示适配器固定部与适配器的位置关系，请参考图8，图8是本申请示意性实施例提供的一种适配器固定部的局部放大图，该适配器固定部19可以包括：多个阵列排布的卡扣结构191，每个卡扣结构191用于固定叠加设置的至少一个适配器20，通常情况下，每个卡扣结构191可以固定叠加设置的至少两个适配器20，此时，可以提高抽拉式组件内设置的线缆的容量，也即是，可以在抽拉式组件内设置更多的线缆，进而可以提高了线缆的转接效率。
综上所述，本申请实施例提供的抽拉式组件，当该抽拉式组件内设置线缆时，可以在滑 道的滑动通道上设置冗余线缆，在托盘处于拉出的状态下，该冗余线缆位于抽拉式组件外，在托盘处于未拉出状态下，该冗余线缆位于抽拉式组件内，因此可以在保证该抽拉式组件能够正常抽拉的前提下，有效的避免了冗余线缆在抽拉式组件外出现杂乱的情况，从而有效的提高了后续对分光箱中的线缆进行维护时的效率。又由于该抽拉式组件中托盘相对于滑道支架的速度与滑道相对于滑道支架的速度的比例为固定值，此时，在托盘的抽拉过程中，该托盘的左右两侧受力均匀，避免了托盘中的设置的线缆受力导致阻碍该托盘的运动，进而使得该托盘可以正常抽拉，因此可以有效的提高了托盘使用的可靠性，当托盘相对于滑道支架的速度与滑道相对于滑道支架的速度的比例为2:1时，若抽拉式组件内设置线缆，可以避免在托盘抽拉过程中，滑动通道上的冗余线缆移动到抽拉式组件外时出现弯折的现象，进而可以对线缆起到保护作用。
本申请实施例还提供了一种插框，请参考图9A，图9A是本申请示意性实施例提供的一种插框02的结构示意图，该插框02可以包括：插框支架021，该插框支架021上设置有多个抽拉式组件10，该多个抽拉式组件10叠加设置在插框支架021内。该抽拉式组件可以为图2示出的抽拉式组件。需要说明的是，图9A仅示意性地示出了一个抽拉式组件10，且图9A示出的为抽拉式组件10中的托盘处于未拉出状态，当该抽拉式组件10中的托盘处于拉出状态时，插框的结构示意图请参考图9B。
可选的，请参考图9C，图9C是本申请示意性实施例提供的一种插框支架021的结构示意图，每个抽拉式组件中的两个滑道支架13可以固定在插框支架021内。
可选的，如图9A和图9B所示，该插框02还可以包括：多组穿线结构022，该多组穿线结构022与多个抽拉式组件10一一对应，每组穿线结构022设置在插框02的两侧，用于支撑对应的位于抽拉式组件10外的线缆。示例的，请参考图9D，图9D是本申请示意性实施例提供的一种抽拉式组件内设置线缆的效果图，该穿线结构022可以支持位于抽拉式组件10外的线缆。
本申请实施例还提供了一种光分箱，该光分箱可以包括：箱体，该箱体内设置有插框，该插框为图9A示出的插框，示例的，该光分箱的结构可以参考图1。
可选的，如图9A和图9B所示，该插框02还包括：插框固定结构023，该插框02可以通过插框固定结构固定在光分箱的箱体内。
以上所述仅为本申请的可选实施例，并不用以限制本申请，凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
