Description

一种转轴连接结构 技术领域
本发明属于led灯具结构件领域，尤其涉及一种转轴连接结构。
背景技术
LED灯具的壳体通常包括面盖与后盖，面盖与后盖的连接如果采用螺丝紧固的方式就会使生产效率降低，而且多个螺丝之间的松紧度也很能保持一致，这就造成了结合面的各个位点上的结合紧密度不一致对灯具的防水性造成影响。现有技术使用转轴连接面盖与后盖，通过杠杆原理将面盖与后盖压紧，使受力由结合面的两端向中心均匀分布，但是现有技术采用的转轴通常使用铆钉铆接，这使得面盖与后盖的拆装都十分的不便利，而且一旦去掉铆钉则面盖与后盖就立即脱离，而多个转轴的铆钉不可能同时去除，所以势必造成面盖与后盖只依靠少数的铆钉连接的状态，在重力影响下铆钉容易扭曲，增加了剩下铆钉的拆除难度，这也给得灯具的维护造成了很多麻烦，特别是如路灯等设置于高空的灯具，在维护的时候携带拆装铆钉的工具十分不便利，而且也有高空坠物的安全隐患，同时由于作业平台的限制导致面盖与后盖的分离也十分的不便利。
公开号为CN104075284A的中国发明专利公开了一种灯具安装组件及灯具，灯具安装组件包括：固定支架，固定支架包括连接板和卡勾部，连接板用以连接灯具本体；活动支架，活动支架包括弧形板和由弧形板延伸而成的卡扣部，卡勾部和卡扣部配合使得活动支架可转动地固定在固定支架上；转轴，转轴穿过两转轴连接部；松紧支架，松紧支架通过转轴可转动地固定在固定支架的两转轴连接部上；其中，连接部为一凸轮结构，使得当松紧支架转动时松紧支架的连接部抵顶支撑活动支架。但是该发明专利的结构复杂，同时结构部件的活动关节过多导致故障率提升。
发明内容
针对现有技术的不足之处本发明提供了仅依靠结构配合以及各个部件位置关系就能在保留转动功能的同时可靠的连接灯具壳体的各个部件，且能做到多个转轴同时分离一种转轴连接结构。
本发明的技术方案是提供一种转轴连接结构，包括第一连接体以及第二连接体，所述的第一连接体与所述的第二连接体扣接，其特征在于：所述的第一连接体包括轴体，所述轴体上设置有窄宽部；所述的第二连接体包括转动腔，所述转动腔的上部设置有卡口；所述的轴体与所述的转动腔转动连接，所述的窄宽部的宽度小于等于所述卡口的宽度。
本发明设置的轴体既能起到转动轴的作用又能与卡口配合形成卡扣式的连接结构，而窄宽部的设置使得轴体能够通过调整与转动腔相对角度而与转动腔分离或者锁紧，在此结构中第一连接体与第二连接体均没有需要相对活动的部件，而是通过设计各个部位的结构形状完成以上功能，这样既能简单的完成连接和转动两个功能，又能减小故障发生的概率；同时。
作为本发明的优选，所述的窄宽部倾斜于通过所述轴体轴心的垂线设置。
作为本发明的优选，所述的窄宽部垂直于通过所述轴体轴心的垂线设置。
作为本发明的优选，所述的轴体上至少对称设置有一组轴向切面，同组所述轴向切面之间的所述轴体形成所述的窄宽部。
作为本发明的优选，所述的第一连接体还包括设置在所述轴体轴向两侧的限位部，所述限位部的上端设置有连接部。
作为本发明的优选，所述第二连接体还包括设置在所述转动腔的轴向两侧与所述限位部配合的稳定台。
作为本发明的优选，所述的稳定台设置在所述转动腔径向面垂直中心线的一侧。
作为本发明的优选，所述的限位部的下端与所述稳定台贴合，所述限位部的下端设置弧形部，所述稳定台与所述限位部的接触面为与所述弧形部配合的弧形面。
作为本发明的优选，还包括设置在所述第一连接体与所述第二连接体的分离方向上的阻挡部件。
作为本发明的优选，所述的稳定台的设置方向与转动方向相反，所述稳定台的对侧方向上设置有用于调节所述第一连接体相对所述第二连接体的最大转动角度的阻挡台，所述限位部上设置有与所述阻挡台配合的内陷部。
本发明设置的阻挡台与内陷部均设置在转动方向一侧，用于调节最大转动角度，由于最大转动角度关系到第一连接体与第二连接体的分离方向，所以这种结构的引入是十分必要的。第一连接体与第二连接体的分离方向为窄宽部正对卡口时第二连接体相对第一连接体的角度位置，而这个角度位置如果和最大转动角度相同则会使路灯等高空灯具在维护时第一连接体与第二连接体的意外脱落率上升，所以如果这个角度没有合理的设计就会有安全隐患，而阻挡台与内陷部的引入可以使最大转动角度与分离的角度错开，并且还能保证在该位置上即使第一连接体与第二连接体各自对应的灯具壳体部件即使只是通过本发明悬挂也不会脱落，这样就能提高本发明在实际使用过程中的安全性。
本发明具有以下有益效果：
本发明拥有拆装简易，故障率低，且能做到同一轴线上的所有卡扣同步拆装的优点。

具体实施方式
以下结合附图对本发明作进一步详细说明。
如图1至图4所示，本发明实施例包括第一连接体1以及第二连接体2。
第一连接体1包括轴体101、限位部102、连接部103以及内陷部104；限位部102设置在轴体101在轴体101两侧，限位部102的上端设置有连接部103。轴体101一般采用圆柱形来增加转动的流畅性，但是也可以使用棱柱形等柱形结构。
第二连接体2包括转动腔201、卡口202、稳定台203以及阻挡台204。卡口202设置在转动腔201的上部，稳定台203设置在转动腔201的两侧，并且位于转动腔201径向面垂直中心线的一侧，既是第一连接体1相对第二连接体2的转动方向的相反一侧。阻挡台204设置在稳定台203的对侧，与转动腔201两侧连接。
限位部102的下端与稳定台203贴合，限位部102的下端设置弧形部1021，稳定台203与限位部102的接触面为与弧形部1021配合的弧形面2031。限位部102可以在第一连接体1与第二连接体2相对转动时同步在稳定台203上转动。稳定台203可以稳定第一连接体1与第二连接体2的相对转动，使第一连接体1与第二连接体2不会因为轴体101的形状而产生转动的卡顿或者偏移等状况。
如图1所示，本发明实施例的稳定台203的设置方向与转动方向相反，稳定台203的对侧方向上设置有用于调节第一连接体1相对第二连接体2的最大转动角度的阻挡台204，限位部102上设置有与阻挡台204配合的内陷部104。内陷部104的内陷宽度以及阻挡台204的厚度配合调整了转动的最大限位以此来调整转动角度，由于路灯在实际安装的时候灯头都是相对水平面成一定角度，所以通过调整内陷部104的内陷宽度以及阻挡台204的厚度来调整最大转动角度可以错开第一连接体1与第二连接体2的分离角度以保证在高空作业的时候灯壳不会因为在最容易停留的最大转动角度上发生脱落状况。灯具设计过程中采用水平面作 为基准面，灯具处于水平状态下进行结构设计，而灯具使用和装配过程中经常处在非水平位置，而这里存在的角度差异往往会对灯具的实际使用、装配和维护造成很大的麻烦，而增设阻挡台204以及内陷部104后方便了后期的模具调整，只需要微调整这两个地方的尺寸即可解决设计和实际之间的角度误差而带来的麻烦，在实际维护、装配和安装中也可以通过增厚补件诸如增加厚度的胶贴等即可调整角度非常方便，而且阻挡台204以及内陷部104在灯具正常工作状态下也不是承力部位，即使改变厚度尺寸也不会影响灯具整体的结构稳定性，更不需要考虑增加厚度的补件本身的强度是否能持久稳定等问题。
如图2至图3所示，本发明实施例的轴体101与转动腔201转动连接。轴体101上对称设置有一组轴向切面1012，同组轴向切面1012之间的轴体101形成中心连线距离小于轴体101径向截面的直径的窄宽部1011。窄宽部1011的宽度小于等于卡口202的宽度。窄宽部1011的主要作用就是使轴体101可以从202中脱出，同时在转动后窄宽部1011相对卡扣202错开角度后，轴体101的直径大于卡口202的宽度使轴体101无法从卡口202中脱出。
如图2所示，本发明实施例的窄宽部1011的第一种实施例为窄宽部1011相对通过轴体101轴心的垂线倾斜设置。此时第一连接体1与第二连接体2的分离角度与窄宽部1011的倾斜角度相同。
如图3所示，本发明实施例的窄宽部1011的第二种实施例为窄宽部1011相对通过轴体101轴心的垂线垂直设置。此时第一连接体1与第二连接体2的分离角度为90度。
如图1所示，本发明实施例在第一连接体1与第二连接体2的分离方向上设置有阻挡部件3。阻挡部件3的安装顺序位于第一连接体1与第二连接体2扣接之后，拆除顺序位于第一连接体1与第二连接体2分离之前，阻挡部件3主要作用就是限制了第一连接体1与第二连接体2的相对水平运动，使第一连接体1的轴体101无法从第二连接体2的转动腔201中脱出，阻挡部件3在实际使用时可以是灯壳的一个与第一连接体1以及第二连接体2均不相连接的壳体部件。
多个本发明的实施例在轴向方向上对齐设置时可以加强连接强度，当转动到分离角度时可以同时分离。
上面所述的实施例仅是对本发明的优选实施方式进行描述，并非对本发明的构思和范围进行限定。在不脱离本发明设计构思的前提下，本领域普通人员对本发明的技术方案做出的各种变型和改进，均应落入到本发明的保护范围，本发明请求保护的技术内容，已经全部记载在权利要求书中。
