请参阅图1至图4，图1是本申请提供的连接机构一实施例的分解结构示意图，图2是本申请提供的螺母一实施例的结构示意图，图3是本申请提供的致动件一实施例的结构示意图，图4是本申请提供的外壳主体的一实施例的结构示意图。
螺母组件10包括螺母11、致动件12和外壳13。外壳13内设有容置空间1312，螺母11、致动件12沿外壳13的长度方向依序设于容置空间1312中。如图1所示，外壳13的长度方向例如为坐标轴的y轴方向。
螺母11的外壁设有第一联动部111。在一些实施方式中，如图1和图2所示，第一联动部111可以为沿长度方向延伸的凹槽。在本实施例中，凹槽可以沿长度方向贯穿螺母11的外壁，即凹槽的长度大于或等于外壁的长度。在其他实施例中，凹槽也可以不贯穿螺母11的外壁，即凹槽的长度小于外壁的长度。可选地，第一联动部111的数量可以根据实际需要进行设置，例如第一联动部111的数量可以是1、2、4和8等。在另一些实施方式中，第一联动部111也可以为沿长度方向延伸的凸起。
可以理解的，螺母11的内壁设有与螺栓20外螺纹配合的内螺纹112，以使得螺母11和螺栓20配合实现紧固。本实施例中，螺母11的内螺纹112形状和大小不作限定，可以根据实际需要进行设置。螺母11材质的硬度大于预设硬度，以使得螺母11的第一联动部111在与致动件12的第二联动部121卡合，螺母11的硬度足够满足致动件12转动时带动螺母11转动。可选地，预设硬度例如为40HRC、55HRC或90HRC。螺母11的材质例如为碳钢、不锈钢、铜质、合金等。
如图1和图3所示，致动件12包括至少一个第二联动部121。第二联动部121可以包括第一连接部1211和自第一连接部1211延伸形成的第二连接部1212。其中，第一连接部1211可以卡设在第一联动部111内，且能够沿长度方向移动。在本实施例中，第一连接部1211为宽度小于或等于上述凹槽的宽度的条形臂，以使得条形臂能够卡设在上述凹槽内，且能够沿长度方向移动。在其他实施方式中，第一连接部1211也可以为凹槽，用于在第一联动部111为凸起时，实现与第一联动部111的卡合。在本实施例中，第二连接部1212可以为设在第一连接部1211上的第一凸起，用于跟随第一连接部1211沿长度方向移动至第一位置，实现与外壳13上的第三联动部1311卡合。在其他实施例中，第二连接部1212也可以为凹槽。可选地，致动件12具体可以呈棘爪结构。
在本实施例中，一个第二联动部121可以与一个第一联动部111和/或一个第三联动部1311卡合。此时，第二联动部121的数量小于或等于第一联动部111的数量，和/或，小于或等于第三联动部1311的数量。例如，第一联动部111为4个、第三联动部1311为8个，则第二联动部121可以为1个、2个、3个或4个，但是不能大于第一联动部111的数量(4个)。当第一联动部111为凹槽，第二连接部1212为第一凸起，第三联动部1311为第二凸起时，凹槽、第一凸起和第二凸起中的至少一者为环状间隔设置，且第一凸起的数量可以小于或等于凹槽的数量和第二凸起的数量。
请参阅图5，图5是本申请提供的螺母组件X-X’位置的一横截面示意图。如图1至图5所示，本实施例中，第一联动部111的数量为4个，第三联动部1311的数量为8个，第二联动部121的数量为4个，且4个第二联动部121的相对于第一联动部111和第三联动部1311均匀设置，对称分布。可选地，在其他实施例中，多个第二联动部121也可不均匀设置，例如，多个第二联动部121相邻设置，即中间仅间隔一个第三联动部1311。
在其他实施例中，多个第二联动部121可以与多个第一联动部111和/或多个第三联动部1311实现卡合。此时，第二联动部121的数量可以大于第一联动部111的数量，也可以大于第三联动部1311的数量。例如，第一联动部111为凹槽，第二联动部121为凸起时，此时，一个第一联动部111内可以仅容纳一个第二联动部121，也可以容纳多个第二联动部121，又例如第二联动部121和第三联动部1311为凸起时，两个第三联动部1311之间可以容纳一个第二联动部121，也可以容纳多个第二联动部121。当第一联动部111为凹槽，第二连接 部1212为第一凸起，第三联动部1311为第二凸起时，第一凸起的数量可以大于凹槽的数量和第二凸起的数量。
可选地，第一凸起远离螺母11的端面A中的至少一个为不垂直于长度方向。如图3所示，第一凸起远离螺母11的端面A中的至少一个为不垂直于长度方向(y轴方向)，即是第一凸起远离螺母11的端面A中的至少一个面为倾斜面，从而能够在第一凸起在沿长度方向移动至两个第二凸起之间的空隙时，能够减少与第二凸起的接触面积，从而能够避免被两个第二凸起卡住。在一些实施方式中，第一凸起远离螺母11的端面A都不垂直于长度方向，以更大程度的减小与第二凸起的接触面积，从而能够避免被两个第二凸起卡住。如图3所示，例如第一凸起远离螺母11的两个端面A都不垂直于长度方向。
在一些实施例中，螺母组件10还包括磁体部件14，磁体部件14位于致动件12远离螺母11的一端，磁体部件14在受到外部磁力的作用下，带动致动件12在第一位置和第二位置之间移动。
在一些实施例中，致动件12还可以包括抵接部122，抵接部122设在螺母11和磁体部件14之间，用于带动第二联动部121在长度方向上移动。第二联动部121自抵接部122的边缘延伸，且设在外壳13与螺母11之间。
可选地，致动件12可以为中空结构，也可以不为中空结构。可以理解的，当螺栓20的螺杆21的长度较短或第二联动部121的长度较长时，抵接部122就可以不与螺杆21相抵接，从而抵接部122可以不设置为中空结构，但是此时的螺杆21的长度仍能够与螺母11配合实现紧固。可以理解的，螺杆21的长度可以小于、等于或大于螺母11的长度。
在一些实施例中，抵接部122的内壁边缘设有承台1221，承台1221用于抵接弹性件142，且可以减小弹性件142的晃动。可以理解的，在抵接部122为中空结构时，且中空部分的直径大于弹性件142的直径时，为了实现抵接部122与弹性件142的抵接，可以在抵接部122的内壁边缘承台1221。如图3所示，抵接部122靠近第二联动部121的内壁边缘设置有一环形承台1221。承台1221的宽度不作限定，承台1221的宽度例如为0.1～0.5厘米。可选地，承台1221可以与抵接部122一体成形，也可以在抵接部122制成后，再在抵接部122的内壁边缘形成承台1221。
如图1所示，磁体部件14包括沿外壳13的长度方向依序设置的被动磁体141和弹性件142。其中，被动磁体141与致动件12连接，弹性件142位于被 动磁体141远离螺母11的一侧，用于在被动磁体141未受到外部磁力作用时，使被动磁体141位于长度方向上的设定位置，即第二位置。弹性件142可以为任何具有弹性形变的部件，即该部件在受外力作用时，就会产生变形，如果将外力去除后，该部件能够恢复它原来的形状和尺寸。弹性件142例如为弹簧。被动磁体141与致动件12连接，以带动致动件12沿长度方向移动。可选地，被动磁体141和致动件12通过焊接或胶水连接。
需要说明的是，本实施例中的被动磁体141仅是为了与后续实施例中的主动磁体52作区分，被动磁体141和主动磁体52可以是任意相互吸引，且磁力足够带动致动件12的磁体，其命名对其不做限制。
在本实施例中，被动磁体141为中空结构，弹性件142贯穿被动磁体141，且一端抵接在抵接部122的承台1221上，另一端抵接在外壳13的第一端部。具体地，被动磁体141为圆环状磁体。在一些实施例中，承台1221也可设置在被动磁体141的内壁边缘，弹性件142抵接被动磁体141的承台1221上。在其他实施例中，被动磁体141可以不为中空结构，弹性件142的一端直接抵接在靠近被动磁体141的一端，另一端抵接在外壳13的第一端部。
在一些实施例中，抵接部122可以为被动磁体141，即是抵接部122直接采用磁性材料制成。在另一些实施例中，致动件12(包括抵接部122和第二联动部121)可以为被动磁体141，即是致动件12直接采用磁性材料制成。此时，弹性件142的一端可以和抵接部122或抵接部122上的承台1221抵接。可选地，弹性件142由导磁的材料制成，从而弹性件142在磁力的作用下可以减小弹性件142的晃动，更好的固定在承台1221上。
可选地，被动磁体141和主动磁体52靠近产生的磁力要足够大，以能够在主动磁体52靠近时，被动磁体141与主动磁体52之间产生的磁力能够带动致动件12沿长度方向移动。
如图1和图4所示，外壳13的内壁设有第三联动部1311。在本实施例中，外壳13包括外壳主体131和盖板132。外壳主体131设有容置空间1312，盖板132设置在外壳主体131的第一端，以作为外壳13的第一端部，螺母11、致动件12和磁体部件14沿靠近第一端部的方向依序设置。可选地，外壳主体131与盖板132通过焊接或胶水连接，以实现外壳主体131和盖板132的固定连接。可以理解的，外壳主体131与盖板132还可以采用其他方式固定连接，本实施例不作限定。外壳主体131与第一端相对的第二侧沿径向方向延伸形成中空的 底板1313，底板1313不与螺母11接触。本实施例中，螺母11不直接与外壳13接触，而是通过第一联动部111与第二联动部121接触，第二联动部121与外壳13上的第三联动部1311接触，以实现与外壳13的间接接触，从而在外壳13转动时，外壳13内的螺母11也能跟随外壳13的转动而转动，从而可以解除紧固。
继续参阅图4，具体地，外壳主体131的内壁设有第三联动部1311。致动件12移动至第一位置时，第三联动部1311用于对第二连接部1212在转动方向(例如X轴方向)上进行限位。具体地，第三联动部1311可以为外壳13的内壁的多个第二凸起，致动件12移动至第一位置时，第二连接部1212位于相邻两个第二凸起之间，从而两个第二凸起对第二连接部1212在转动方向上进行限位。在其他实施例中，第三联动部1311也可以为外壳13的内壁的一个第二凸起，致动件12移动至第一位置时，第二连接部1212位于第二凸起的一侧，从而该第二凸起抵接第二联动部121，并推动第二联动部121沿外壳13宽度方向(X轴方向)转动。可选地，当第二联动部121的第二连接部1212为凸起时，第三联动部1311可以为外壳13的内壁的多个凹槽，凹槽和凸起可以实现卡合。
如图1和图4所示，可选地，第二凸起远离磁体部件14的端面中的至少一个为不垂直于长度方向，即是第二凸起远离磁体部件14的端面B中的至少一个面为倾斜面，从而能够在第一凸起在沿长度方向移动至两个第二凸起之间的空隙时，能够减少与第一凸起的接触面积，从而能够避免卡住第一凸起。在一些实施方式中，第二凸起远离磁体部件14的端面都不垂直于长度方向，以更大程度的减小与第一凸起的接触面积，从而能够避免卡住第一凸起。
在一些实施方式中，螺母组件10还可以包括隔离件15，隔离件15设置在底板1313的中空位置，且与螺母11接触。其中，底板1313的中空位置的直径小于致动件12的最大直径，以避免外壳13与螺母11脱离。隔离件15用于将螺母11的底面和外壳13的底板1313隔离，以防止解除联动结构且外壳13相对于螺栓20转动时，螺母11的底面和外壳13的底板1313直接接触产生的摩擦力会使螺母11转动。可选地，隔离件15例如为垫圈，垫圈的材质可以为橡胶、硅胶等。
请参阅图6至图7，图6是本申请提供的螺母组件组成联动结构的E-E’纵截面示意图，图7是本申请图6中H区域的放大示意图。
进一步，如图7所示，隔离件15的高度大于底板1313的高度，从而可以 将螺母11的底面和外壳13的底板1313隔离。
请参阅图8，图8是本申请提供的螺母组件解除联动结构的F-F’纵截面示意图。
如图6和图8所示，磁体部件14在受到外部磁力作用下，带动致动件12在长度方向上移动至第一位置，使得第一联动部111、第二联动部121和第三联动部1311组成联动结构，联动结构能够使螺母11跟随外壳13转动；磁体部件14在未受到外部磁力作用下，带动致动件12在长度方向上移动至第二位置，使得第一联动部111、第二联动部121和第三联动部1311解除联动结构。
具体地，如图6所示，磁体部件14中的被动磁体141在受到主动磁体52的作用下，带动致动件12在长度方向上移动至第一位置，即解锁位置，此时，第二联动部121的第一连接部1211与第一联动部111卡合，第二联动部121的第二连接部1212与第三联动部1311卡合，从而第一联动部111、第二联动部121和第三联动部1311组成联动结构，联动结构能够使螺母11跟随外壳13转动。具体地，组成联动结构时，一边致动件12的条形臂卡合在螺母11的凹槽内，另一边致动件12的第一凸起卡合在外壳主体131的两个第二凸起之间，从而凹槽、条形臂、第一凸起和第二凸起组成联动结构，联动结构能够使螺母11跟随外壳13转动。可以理解的，处于解锁状态的螺母组件可以采用扳手或其他常用拆卸工具进行拆卸，非常方便。
具体地，如图8所示，磁体部件14中的被动磁体141在未受到主动磁体52的作用下，带动致动件12在长度方向上移动至第二位置，即锁定位置，此时，第二联动部121的第一连接部1211与第一联动部111卡合，但是第二联动部121的第二连接部1212与第三联动部1311错开，从而第一联动部111、第二联动部121和第三联动部1311解除联动结构，此时，螺母11不能跟随外壳13转动。具体地，解除联动结构时，一边致动件12的条形臂仍卡合在螺母11的凹槽内，但是另一边致动件12的第一凸起靠近外壳13的底面，与第二凸起错开，从而凹槽、条形臂、第一凸起和第二凸起解除联动结构。
在一个具体实施例中，第一联动部111的数量为4个，第三联动部1311的数量为8个，第二联动部121的数量为4个，例如螺母11扭矩为40-80NM，则单个第二联动部121(棘爪)承载扭矩为等于螺母11的扭矩除以第二联动部121的数量，为10-20NM，进一步，第一连接部1211(力臂)的长度为9.5mm，则第二联动部121(棘爪)的剪切力为螺母11的扭矩除以力臂的长度，为 1000-2000N，第二联动部121(棘爪)的剪力面积26mm 2，则第二联动部121的剪切强度等于棘爪的剪切力除以棘爪的剪力面积，为40-80Mpa，可选地，螺母11、致动件12以及外壳13可采用铝合金或钛合金的材料制成。其中，当螺母11、致动件12以及外壳13采用铝合金材料制成时，铝合金的剪切强度为310MPA，经计算，螺母组件10的强度40-80Mpa小于310MPA，所以在外壳13转动时，致动件12的强度小于制备材料的强度，满足强度要求，从而避免在联动结构转动时，螺母11、致动件12以及外壳13中的任一个损坏，导致螺母组件10不能正常转动。
本实施例中，通过在外壳内设有容置空间，螺母和致动件沿外壳的长度方向依序设于容置空间中，螺母的外壁设有第一联动部、致动件包括至少一个第二联动部，外壳的内壁设有第三联动部；其中，所述致动件能够在第一位置和第二位置之间移动，在所述第一位置时，第一联动部、第二联动部和第三联动部组成联动结构，联动结构能够使螺母跟随外壳转动，从而可以实现组装，在所述第二位置时，第一联动部、第二联动部和第三联动部解除联动结构，从而可以实现防盗，且可靠性高；其次，上述螺母组件的结构简单、组装简易且生产成本低。。
请继续参阅图1至图8，本实施例中，连接机构100包括上述任一实施例中的螺母组件10和螺栓20。其中，螺栓20用于螺纹连接于螺母组件10中的螺母11。
螺栓20是由螺杆21和头部22两部分组成的一类紧固件，需与螺母11配合，用于紧固连接两个带有通孔的零件，即第一零件31和第二零件32。当需要将两个零件分开时，可以将螺母11从螺杆21上旋出，从而可以使这两个零件分开。可选地，螺杆21可以为带有外螺纹的圆柱体，头部可以为六角头、圆头、方形、沉头等。其中，螺栓可以按头部形状分类为六角头螺栓、圆头螺栓、方形螺栓、沉头螺栓。
螺母11内壁上的内螺纹112可以与螺杆21上的外螺纹配合，实现紧固。内螺纹112和外螺纹的圈数可以根据实际需要进行选择，此处不作限定。
请参阅图9，图9是本申请提供的连接机构一应用场景的示意图。
如图9所示，一个带孔的第一零件31与基站40固定连接，另一个带孔的第二零件32与基站40活动连接，第一零件31与第二零件32重叠时，其上的通孔能够相对应，以使得连接机构100穿设于上述通孔，以紧固连接第一零件 31与第二零件32，从而可以将基站40进行固定，固定之后，不知道解锁方法的用户通过旋转外壳13，使外壳13转动，但是里面的螺母11不会转动，从而不能进行解锁，进而可以实现户外基站的防盗。基站40的型号例如可以为BWT-PRO3800C户外型号。本实施例提供的连接机构100能够兼容各种不同尺寸的户外基站产品。
请继续参阅图10，图10是本申请提供的拆卸元件的一实施例的结构示意图，图11是本申请提供的拆卸元件的N-N’位置的纵截面示意图。
本实施例中，拆卸元件50包括壳体51和主动磁体52。其中，壳体51设置有容纳槽53，容纳槽53内设主动磁体52。
壳体51内壁的形状与螺母组件10的外壳13形状匹配，以使壳体51的转动能够带动螺母组件10的外壳13转动。例如螺母组件10的外壳13的形状为六面棱柱，则壳体51内壁的形状也可以为六面棱柱，从而在螺母组件10位于容纳槽53内时，外壳13可以跟随壳体51的转动而转动。
螺母组件10设有被动磁体141和螺母11，被动磁体141用于在主动磁体52的磁力作用下，实现螺母11与螺母组件10的外壳13之间的联动结构，以使螺母11能跟随外壳13转动。
在其他实施例中，主动磁体52可以设置于壳体51上方，或者可以将壳体51的顶部设置为主动磁体52，或者主动磁体52可以单独设置。
在一些实施方式中，壳体51还可以包括第一柱体511和第二柱体512，第二柱体512连接在第一柱体511远离外壳的一端，且第一柱体511的轴线与第二柱体512的轴线垂直。在其他实施方式中，第一柱体511的轴线与第二柱体512的轴线也可以不垂直。可选地，第一柱体511与第二柱体512可以固定连接，也可以可拆卸连接。可选地，第二柱体512的两端设置有防滑件(图未示)，以增大摩擦力，从而使得用户在握住第二柱体512的两端转动外壳时，能够避免用户从第二柱体512的两端滑落，进而可以提高拆卸效率。
在另一些实施方式中，即拆卸元件50还可以包括动力部(图未示)，动力部与壳体51连接，可带动壳体51转动，从而可以使得螺母组件10的外壳13转动，进而可以使得里面的螺母11转动。其中，动力部可以由电力驱动，使其发生自转，从而带动壳体51转动，可以避免手动转动壳体51，还可以提高连接机构的组装效率。可选地，动力部例如为包括电机的电转。
本实施例中，通过将主动磁体设置在拆卸元件中外壳的容纳槽内，壳体内 壁的形状与螺母组件的外壳形状匹配，从而当壳体的容纳槽套在螺母组件外壳上时，容纳槽顶部的主动磁体吸引螺母组件内的被动磁体沿外壳长度方向向上运动至第一位置，此时转动拆卸元件才可以实现连接机构的解锁，其中，将主动磁体与拆卸工具进行组合，可以实现组合联动机构的同时，还可以直接进行拆卸，提升了连接机构的组装的便利性。
以上所述仅为本申请的实施例，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
