 本发明的实施方式
下面结合附图和实施例对本申请进一步说明。
以下将结合实施例和附图对本申请的构思、具体结构及产生的技术效果进行清楚、完整地描述，以充分地理解本申请的目的、特征和效果。显然，所描述的实施例只是本申请的一部分实施例，而不是全部实施例，基于本申请的实施例，本领域的技术人员在不付出创造性劳动的前提下所获得的其他实施例，均属于本申请保护的范围。另外，专利中涉及到的所有联接/连接关系，并非单指构件直接相接，而是指可根据具体实施情况，通过添加或减少联接辅件，来组成更优的联接结构。本申请创造中的各个技术特征，在不互相矛盾冲突的前提下可以交互组合。
参照图1、图2所示，本申请揭示了一种超薄型平直连接锁装置，通过该装置实现多个框架之间的连接，具体的，包括分别位于相邻框架10上的连接组件20，且连接组件20包括呈半圆状的固定座201和旋转座202；由于连接组件20的结构完全相同，本实施例中，以其中一个框架10上的连接组件20的结构进行详细说明，其中，框架10呈方形，为了实现相邻框架10之间的稳固连接，框架10的每条边上均分布着两个连接组件20；参照图2所示，固定座201上设置有螺丝孔2011和定位柱2012，对应的，框架10上设置有螺纹孔101和定位孔102，固定座201上的定位柱2012插入定位孔102内，实现定位，再通过向螺丝孔2011和螺纹孔101内锁入螺钉，以实现固定座201的固定。
结合图3所示，对于固定座201和旋转座202的具体结构，本申请提供了一具体实施例，固定座201和旋转座202均呈半圆环状，固定座201上设置有呈圆弧形的第一圆弧凹槽2013和第一圆弧凸台2014，旋转座202上设置有呈圆弧形的第二圆弧凸台2021和第二圆弧凹槽2022，并且，第一圆弧凹槽2013位于第一圆弧凸台2014的内侧，第二圆弧凸台2021位于第二圆弧凹槽2022的内侧；因此，可以理解的是，第一圆弧凸台2014、第一圆弧凹槽2013、第二圆弧凸台2021、以及第二圆弧凹槽2022均呈半圆环状。第一圆弧凹槽2013和第二圆弧凹槽2022的开口处均设置有导向斜坡203，以避免旋转座202转动过程中出现卡顿。
当固定座201固定安装在框架10上后，旋转座202则位于固定座201的下方，并且旋转座202的第二圆弧凸台2021被限位在第一圆弧凹槽2013内，第一圆弧凸台2014被限位在第二圆弧凹槽2022内；结合图4所示，当第一框架103上与第二框架104相对接时，两组连接组件20的固定座201和旋转座202分别相对接，两个固定座201组成完整的圆环，两个旋转座202也组成完整的圆环；结合图5所示，当两组连接组件20的旋转座202转动后，本方案中，旋转座202的转动角度为90°，即转动到极限位置，其中两个固定座201分别对两组连接组件20的旋转座202实现限位，以实现相邻框架10的连接，从而完成相邻框架10的锁紧拼接。此时第一圆弧凹槽2013同时将两个旋转座202的第二圆弧凸台2021卡在里面，使两个旋转座202不能做上下左右的相对移动；同理第二圆弧凹槽2022同时将两个固定座201的第一圆弧凸台2014卡在里面，使两个固定座201不能做上下左右的相对移动，这样就实现了两个框架10之间的上下左右之间的锁紧。同时第二圆弧凹槽2022和第一圆弧凸台2014、第一圆弧凹槽2013和第二圆弧凸台2021之间的配合，使两个固定座201和两个旋转座202都不能做前后方向的相对移动。
通过上述的连接方式，当多个相邻框架10需要进行拼接时，如图5所示，提供了四块框架10相拼接的具体实施例，包括第一框架103、第二框架104、第三框架105以及第四框架106，从而实现多块框架10的拼接，以满足现有技术中关于户外大屏显示的需求。本申请的此种超薄型平直连接锁装置，用于对厚度尺寸要求较高的复合材料框架10上；既能保证使用该装置后产品的厚度尺寸超薄，又能保证产品不用工具就能轻松进行快速拼接和拆卸。
对于上述的实施例，更为具体的，参照图3所示，所述第二圆弧凹槽2022的外侧设置有第三圆弧凸台2023，第三圆弧凸台2023的外侧设置有向外凸出的旋转把手2024，通过转动旋转把手2024，实现旋转座202的转动；进一步的，第三圆弧凸台2023内壁的一端上设置有弧形的第一限位凹槽2025，第三圆弧凸台2023内壁的另一端设置有限位缺口，该限位缺口为第二限位凹槽2026；所述的固定座201的两端分别设置有一限位凸台2015，两个限位凸台2015分别位于第一限位凹槽2025和第二限位凹槽2026内。限位凸台2015和第二限位凹槽2026的相互配合能保证旋转座202安装后能在预设的角度范围内相对固定座201做旋转运动，且一直卡在固定座201下面不会脱出。
上述的方案中，所述第一限位凹槽2025的止点位于第三圆弧凸台2023的中部，因此第一限位凹槽2025的长度即为第三圆弧凸台2023的一半；所述的旋转座202转动后，固定座201的限位凸台2015位于第一限位凹槽2025的止点位置。结合图4所示，为旋转座202未转动前的状态，图5即为旋转座202转动后的状态。需要说明的是，第一限位凹槽2025的长度可以根据实际情况进行调整，例如在另一具体实施例中，第一限位凹槽2025的长度为第一圆弧凸台2014的3/4，此时旋转座202的转动角度则大于90°。
在上述的实施例中，结合图3所示，固定座201呈半圆环状，其中心设置有半圆形缺口，这种结构，在固定座201上形成呈圆弧形的中心圆弧凸台2016，第一圆弧凹槽2013位于第一圆弧凸台2014和中心圆弧凸台2016之间。当固定座201与旋转座202相组合后，第二圆弧凸台2021则位于第一圆弧凹槽2013内，使第二圆弧凸台2021位于第一圆弧凸台2014和中心圆弧凸台2016之间，实现两者的卡紧，两者之间缝隙能保证两个零件能够相对滑动不卡死，又能保证两零件紧密配合无明显晃动。上述的螺丝孔2011穿过于中心圆弧凸台2016，均匀分布在中心圆弧凸台2016上。
对于所述的固定座201和旋转座202，本申请还提供了一具体实施例，在上述实施例的基础上，该实施例中，固定座201和旋转座202之间设置有对两者进行相对位置限定的限位组件，通过限位组件，对旋转座202的初始状态和最终状态进行位置限定，以提高使用的方便性，避免固定座201和旋转座202在未受转动力的情况下而出现的松动。
结合图7、图8所示，对于上述的限位组件，本申请提供了一具体实施例，限位组件包括弹性限位片301和第三限位凹槽302，所述的弹性限位片301设置在第一圆弧凹槽内，第三限位凹槽302设置在第二圆弧凸台上，通过弹性限位片301和第三限位凹槽302的配合，实现固定座201和旋转座202的锁紧。更为具体的，所述的弹性限位片301和第三限位凹槽302分别设置有两组，当旋转座202处于原始状态和转动后的状态时，弹性限位片301则分别卡入相应的第三限位凹槽302内。此时若无外部推力，旋转座202将被卡住不能自由旋转，限位弹性限位片301与两个第三限位凹槽302的相互配合，能保证旋转座202按顺时针旋转到最大角度时（连接组件20处于完全松开的状态）及旋转座202按逆时针旋转到最大角度时（连接组件20处于完全锁紧的状态）都有一个弹性的限位状态，能避免震动或其它外部因素使得旋转座202自由旋转不利于安装及锁紧后松脱的风险。
结合图9、图10所示，对于上述的限位组件，本申请还提供了一具体实施例，限位组件包括限位球头柱塞303和限位孔304，限位球头柱塞303安装在固定座201上，限位孔304位于第二圆弧凹槽2022内，通过限位球头柱塞303与限位孔304的配合，能够起到图7、图8所示实施例中的效果，因此本实施例中不再对其效果进行说明。
本申请的超薄型平直连接锁装置，利用固定座201和旋转座202上的圆弧凸台和圆弧凹槽相互配合实现锁紧限位，保证整个装置的厚度薄，满足各种对尺寸要求严苛的使用环境，装置结构简单，制作难度和成本较低，操作使用简单、无需辅助工具。
另外，本申请还提供了一具体实施例，该实施例中提出了一种micro led显示屏，并且，该micro led显示屏包括上述任意实施例中所述的超薄型平直连接锁装置。
以上是对本申请的较佳实施进行了具体说明，但本申请创造并不限于所述实施例，熟悉本领域的技术人员在不违背本申请精神的前提下还可做出种种的等同变形或替换，这些等同的变形或替换均包含在本申请权利要求所限定的范围内。
