背景技术
服务器内部通常安装至少两个节点模块，每个节点模块可以从服务器中抽出，当两个或以上节点模块同时抽出时，造成服务器的重心偏移，重心移至服务器外壳之外，容易导致服务器倾斜掉落。
因此在操作时，需要操作人员时间注意不要同时抽出两个节点模块，但人为操作难以保证不出现错误，因此服务器倾倒的问题时有发生，特别是在实验室中进行测试时，服务器未安装于服务器机架上，倾倒现象更容易发生。
目前在家具领域，为了防止两个抽屉同时被抽出，也设置了相应的锁定结构，现有的防止抽屉同时抽出来的结构方案占用了前端两侧的空间。但对于横向阵列服务器节点前端空间以及节点左右两侧空间受限的系统构架下，例如1U或者2U高度的机箱，侧边被滑轨占用，不能使用现有的技术方案。再者，服务器节点的内部模组存在需要从侧面维护的场景，服务器节点侧边的空间不能被联动互锁结构或者滑轨占用，否则会影响节点模组内侧维护。
对于本领域的技术人员来说，如何在不占用节点模块前端两侧空间的情况下，保证节点模块无法同时被抽出，是目前需要解决的技术问题。

具体实施方式
本申请的核心在于提供一种节点安全锁定装置，在不占用节点模块前端两侧空间的情况下，当一个节点模块抽出时，防止其他对应的节点模块抽出，降低服务器倾倒的风险。
为了使本领域的技术人员更好地理解本申请的技术方案，下面将结合附图及具体的实施方式，对本申请的节点安全锁定装置进行详细的介绍说明。
本申请提供一种节点安全锁定装置，如图1A所示，为节点安全锁定装置与机箱相互装配的结构图，图中A表示机箱，B表示节点模块。图1B为节点安全锁定装置各部件的爆炸图；图1C为节点安全锁定装置组装状态下从外侧观察的正视图。该装置包括外轨1，外轨1固定安装在机箱上，外轨1设置于相邻两个节点模块之间，起到导向限位的作用；每个节点模块对应一个外轨1，两个外轨1相对固定设置形成一体；外轨1上设置导向孔11，导向孔11内滑动装配联动互锁杆2，联动互锁杆2可沿导向孔11移动，改变自身所处的位置，联动互锁杆2可以移动到解锁位置和锁定位置；联动互锁杆2的移动路径与其自身的长度方向垂直。
联动互锁杆2的移动与节点模块相关，一个联动互锁杆2与两个节点模块相互配合；当联动互锁杆2位于解锁位置时，各个节点模块不受阻挡，都可独立被抽出；当联动互锁杆2位于锁定位置时，联动互锁杆2对未被抽出的节点模块产生阻挡，此时未被抽出的处于初始位置的节点模块无法被向外抽出，初始位置也即节点模块完全回缩到机箱内部时各部件所处的位置。
外轨1上滑动装配中轨3，每个中轨3由一个节点模块带动同向平移，中轨3的移动方向与节点模块的移动方向平行；中轨3可相对于外轨1移动，中轨3由节点模块带动，如图2A所示，为节点安全锁定装置中外轨1的结构示意图，OUTER表示外端，INNER表示内端。中轨3沿图中双向箭头所示的方向移动， 也即中轨3的移动方向与外轨1的长度方向一致；结合图1C所示，两个外轨1相互接触，在两个外轨1之间安装中轨3等结构。导向孔11贯穿外轨1，并且导向孔11的导向方向沿图2A中的竖直方向，联动互锁杆2贯穿插入导向孔11中，沿竖直方向滑动，联动互锁杆2的移动方向与中轨3的移动方向垂直；图2A中导向孔11下方为锁定位置(LOCK)，上方为解锁位置(UNLOCK)。
如图2B所示，为节点安全锁定装置中的中轨3结构示意图，图中表示两个中轨3；中轨3上分别设置上锁导向斜边31、解锁导向斜边32和阻挡锁定边33；上锁导向斜边31、解锁导向斜边32和阻挡锁定边33分别为凸出于中轨3自身板面的外凸结构，上锁导向斜边31和解锁导向斜边32为倾斜设置的直线形或弧形结构，阻挡锁定边33为竖向设置的结构。
当中轨3从初始位置向外移动时，上锁导向斜边31带动联动互锁杆2移动到锁定位置；当中轨3向内移动到初始位置时，解锁导向斜边32带动联动互锁杆2移动到解锁位置；中轨3位于初始位置时，阻挡锁定边33受到位于锁定位置的联动互锁杆2阻挡，使对应的节点模块无法向外移动。
结合图2B所示，当中轨3沿图中单箭头朝向左下方移动时，也即中轨随节点模块向外抽出移动，由于上锁导向斜边31倾斜设置，因此上锁导向斜边31对联动互锁杆2施加向下方的推力，使联动互锁杆2向下移动到锁定位置；当联动互锁杆2位于锁定位置时，联动互锁杆2受到导向孔11的限位无法沿外轨1的长度方向移动，因此联动互锁杆2能够阻挡位于初始位置的中轨3向外移动，进而阻挡节点模块向外移动。
当中轨3沿图中双箭头朝向右上方移动时，也即中轨随节点模块向内移动，由于解锁导向斜边32倾斜设置，因此解锁导向斜边32对联动互锁杆2施加向上方的推力，使联动互锁杆2向上移动到解锁位置。
如图3A和图3B所示，分别为联动互锁杆2处于解锁位置和锁定位置的示意图，图3A和图3B分别展示了两个不同的中轨，图3A相当于从第一侧观察，图3B相当于从第二侧观察。结合图3A所示，当向外抽出其中位于第一侧的节点模块时，第一侧的中轨3沿箭头向右移动，上锁导向斜边31向右移动与联动互锁杆2接触，联动互锁杆2只能竖直上下移动，上锁导向斜边31推动联动互锁杆2逐渐向下移动，使联动互锁杆2到达图3B状态的锁定位置。
结合图3B所示，从第二侧观察，位于第二侧的中轨3处于始终位置，当联动互锁杆2向下移动到达锁定位置时，联动互锁杆2位于阻挡锁定边33的外侧，阻挡锁定边33受到联动互锁杆2的阻挡无法向外移动，进而使第二侧的中轨3无法向外移动。
本申请的联动互锁杆2与两个节点模块相关联，每个节点块都可单独地驱动联动互锁杆2，改变联动互锁杆2所处的位置；当其中一个节点模块向外被抽出时，驱动联动互锁杆2移动到锁定位置，从而限定其他节点模块无法被抽出；当抽出的节点模块重新被推回时，带动联动互锁杆2从锁定位置移动到解锁位置，此时任意一个节点模块可以单独移动。该装置可以防止两个节点模块同时移出服 务器，避免服务器的侧倾问题。
外轨1上固定安装阻尼块12，如图2C所示，为阻尼块12的结构示意图；阻尼块12用于弹性限位联动互锁杆2处于锁定位置和解锁位置，联动互锁杆2在锁定位置和解锁位置之间变换时产生阻尼。具体地，阻尼块12为板状结构，可由塑胶材料制成，在阻尼块12的一其中一条侧边处设置两个限位弧121，限位弧121与联动互锁杆2的外周形状相匹配，当联动互锁杆2在导向孔11中移动时，在两个限位弧121之间转移，当联动互锁杆2处于其中一个限位弧121之内时，联动互锁杆2对限位弧121基本不产生压力，当联动互锁杆2从一个限位弧121移动到另一个限位弧121时，需要越过两个限位弧121之间的凸起结构，此时就会对这个凸起结构产生压力，对联动互锁杆2的移动产生一定阻力，以防止联动互锁杆2的位置产生异常的偏移，在没有其他外力的情况下，联动互锁杆2恰好处于两个限位弧121其中之一的位置。
具体地，阻尼块12夹装在两个外轨1之间的位置，通过其板面上凸出设置的两组定位柱插装在两个外轨1上，使阻尼块12与外轨1相对固定。虽然阻尼块12由塑胶材料制成，具有一定的弹性，但为了使联动互锁杆2更容易在两个限位弧121之间转移，两个限位弧121仅两端与阻尼块12的本体连接为一体，中间部分不与阻尼块12的本体接触，限位弧121更易变形。当然，若阻尼块12自身采用橡胶等弹性较好的材料制成，也无需设置此缝隙结构。
中轨3上安装中轨止动钉34，中轨止动钉34无法相对于中轨3自身的长度方向移动，中轨止动钉34和中轨3同步沿外轨1的长度方向滑动；如图2A所示，外轨1上设置止动导向边13，止动导向边13朝向中轨3的方向凸出于外轨1的侧面，止动导向边13位于外轨1靠近外端的位置，当止动导向边13阻挡中轨止动钉34时，限定中轨3向外移动的最外位置，当中轨随节点模块向外移动时，向图2A中的左下方移动，当中轨止动钉34被止动导向边13阻挡时，无法继续向外移动，防止中轨3完全脱离外轨1。
更进一步，本申请在中轨3上滑动连接内轨4，如图2D所示，为节点安全锁定装置节点安全锁定装置的内轨结构图；内轨4固定连接节点模块，与节点模块同步移动，图2D中的C表示连接板，用于与节点模块的内端固定，连接板与内轨4的主体部分相互垂直，内轨4的主体部分后连接于中轨3。
内轨4上设置止动卡钩41，图2E为止动卡钩41的结构示意图；止动卡钩41能够带动中轨止动钉34使中轨3随节点模块同步向外移动。
结合图2B所示，中轨3上设置中轨止动滑道35，中轨止动滑道35的长度方向沿竖向，横向贯通中轨3，中轨止动钉34滑动安装在中轨止动滑道35中，中轨止动钉34能够沿竖向滑动，中轨止动钉34相对于中轨止动滑道35移动时能够到达止动位和可动位；当中轨3向外移动到最外位置时，止动导向边13推动中轨止动钉34，使中轨止动钉34移动到可动位；当中轨止动钉34位于止动位时，中轨止动钉34与止动卡钩41接触配合，对止动卡钩41形成阻挡，进而使内轨无法继续向外移动；当中轨止动钉34位于可动位时，中轨止动钉34与止 动卡钩41解除配合，止动卡钩41不受中轨止动钉34的阻挡，内轨可继续向外移动，内轨4相对于中轨3独立移动。
结合图2D所示，内轨4上设置止动复位斜边42，当内轨4随节点模块向内移动时，止动复位斜边42带动中轨止动钉34移动到止动位，此时中轨止动钉34重新对止动卡钩41移动阻挡。
中轨3上安装复位弹簧37，复位弹簧37对中轨止动钉34施加托举弹力，复位弹簧37对中轨止动钉34产生向上的弹力，避免中轨止动钉34向下掉落。
中轨3的侧面凸出设置止动抽芽36，止动抽芽36凸出于中轨3的侧面；止动抽芽36相对于中轨止动钉34更靠外伸端；当中轨止动钉34被止动导向边13推动到可动位时，止动卡钩41不受中轨止动钉34的阻挡继续向外移动，此时内轨4可相对于中轨3移动，为了避免内轨4完全脱离中轨3，在中轨3上设置了止动抽芽36，止动抽芽36固定在中轨3上，止动抽芽36用于阻挡止动卡钩41，防止内轨4与中轨3完全脱离。
图4A为本申请的节点安全锁定装置节点安全锁定装置处于初始状态的示意图，图4B为本申请的节点安全锁定装置节点安全锁定装置其中一侧的内轨和中轨向外抽出状态的示意图；图5A为初始状态下内节点安全锁定装置节点安全锁定装置内端部的局部示意图，相当于图4A左侧的局部构造；图5B为中轨止动钉34与止动导向边13相互配合状态的局部示意图；图5C为中轨止动钉34与止动抽芽36配合的局部结构图。
结合图4A、图4B、图5A至图5C所示，在图5A的初始位置时，中轨止动钉34位于靠下的止动位，此时止动卡钩41顶在中轨止动钉34上，节点模块与内轨4同步移动，通过止动卡钩41和中轨止动钉34的传动，内轨4带动中轨3同步向外移动。
内轨4带动中轨3同步向外移动，当中轨止动钉34与止动导向边13接触时，止动导向边13的斜边推动中轨止动钉34向上移动到可动位，此时内轨4能够独立地相对于中轨3移动。
内轨4继续向外移动，到达图5C所示的位置，受到止动抽芽36的阻挡，此时内轨4无法继续向外移动；此时中轨3受到外轨1上止动导向边13的阻挡无法向外移动，内轨4受到中轨3上的止动抽芽36的阻挡，此时节点模块向外移动到最大位置。
结合图2E所示，止动卡钩41包括止动顶推面411、复位弹性臂412、转动连接件413、按压臂414，止动顶推面411为竖向的表面，按压臂414朝向外侧呈横向延伸。止动顶推面411用于与中轨止动钉34或止动抽芽36配合止动。
止动卡钩41通过转动连接件413转动连接于内轨4，止动卡钩41只能转动，无法相对于内轨4移动。按压臂414朝向外侧延伸，当内轨4向外移动到最大位置时，可供操作人员按压，对按压臂414施加向下的压力能够使止动卡钩41围绕转动连接件413转动，复位弹性臂412的一端可与内轨4接触，止动卡钩41转动时挤压复位弹性臂412发生弹性变形，此时止动顶推面411不再与止动抽芽 36接触形成阻挡，内轨4可以完全与中轨3分离，从而将整个节点模块从机箱中取出。解除外力时复位弹性臂412使止动卡钩41复位，重新发挥阻挡的作用。
图1C为节点安全锁定装置的截面示意图；两个外轨1背向固定连接，结合图2A，外轨1的上边缘和下边缘分别背向弯折形成限位折边，也即两个外轨1的限位折边弯折的朝向相互背离，限位折边处呈U形弯折实现导向。
中轨3滑动装配在外轨1中，结合图2B，中轨3的上边缘和下边缘分别背向弯折形成限位折边，中轨3的边缘和下边缘形成的限位折边与外轨1上的限位折边形相同，中轨3的限位折边滑动安装在外轨1上的限位折边之内。
两个内轨4主体部分的上边缘和下边缘分别相对弯折形成限位折边，结合图2D所示，两个内轨4的主体部分分别卡入中轨3，内轨4的限位折边滑动装配在中轨3的限位折边之内，两个内轨4的限位折边的弯折方向相互靠近。内轨4主体部分的限位折边的具体尺寸与中轨3上的限位折边宽度相等。
结合图1C所示，在外轨1和中轨3的中间位置分别相背冲压形成U形槽结构，两个外轨1相互对接固定后，两者的U形槽结构拼接形成一个空腔，该空腔长度方向的两端与外界贯通，在此空腔内安装后文中涉及的解锁连杆5。
在上述任一技术方案及其相互组合的基础上，本申请还包括解锁连杆5，解锁连杆5的延伸方向与节点模块的移动方向平行，解锁连杆5可沿长度方向移动；解锁连杆5的内伸端设置解锁斜边51，当解锁连杆5沿解锁方向移动时，解锁斜边51带动联动互锁杆2从锁定位置移动到解锁位置。通过解锁连杆5可以独立地将联动互锁杆2移动到解锁状态，从而解除对其他节点模块的锁定。
具体地，解锁方向平行于节点模块移动方向，解锁连杆5的外伸端转动连接解锁把手52，转动解锁把手52时能够带动解锁连杆5与节点模块平行的方向向外移动实现解锁。
如图6A所示，为解锁连杆5的结构示意图；图6B为解锁连杆5推动联动互锁杆2的过程示意图；结合图7A和图7B所示，分别为解锁连杆5未解锁状态的外端局部结构图和内端局部结构图；图8A和图8B分别为解锁连杆5解锁状态的外端局部结构图和内端局部结构图。
解锁连杆5的长度方向与节点模块的移动方向平行；结合图6B所示，下方的解锁连杆5处于未解锁状态，先按弯箭头①转动解锁把手52，解锁把手52与外轨1接触，并使解锁连杆5沿箭头②方向移动，使解锁斜边51推动联动互锁杆2沿箭头③方向移动，到达上方的解锁连杆5所处的状态。
本申请还提供一种服务器，包括上述的节点安全锁定装置，该服务器能够实现相同的技术效果。
