Description

一种LED组合屏快速锁固机构 技术领域
本发明涉及LED电子显示屏技术领域，具体的说，是涉及一种LED组合屏快速锁固机构。
背景技术
LED电子显示屏由于出色的显示效果及适用性，在舞台、商演、广告、会展等行业得到了广泛应用。LED电子显示屏一般由较小的单元屏组成，当显示面积需求较大时，可能需要几十甚至上百块单元屏拼装在一起使用，需要消耗显示屏提供商大量的人力物力去安装及拆卸。随着显示屏租赁市场的日益成熟，对于显示屏拼装及拆卸的便捷性及安全性也提出了更高的要求。传统的LED显示屏一般采用箱体边锁、拉动锁或连接片等零件进行单元屏的拼装，固定单元屏体时必须使用辅助安装工具，单人拼装困难，耗时且不省力，单元屏体之间的定位需依靠另外加装定位销，拼缝间隙难以控制，组装后的显示屏不便于拆卸，传统的拼装结构尤其不适用于对拼缝精度要求较高的高分辨率显示屏。
传统的LED显示屏拼装结构主要有以下几种结构形式：
1、箱体边锁
这种箱体边锁为最常规的LED显示屏单元锁固方式，成本较低但锁固时必须另外使用六角扳手等工具，操作时不省力，且长期多次使用后易造成钩锁变形进而导致单元之间锁固精度降低，且因为无法预固定，所以不适合吊装。
2、改进型箱体边锁
改进型箱体边锁将六角扳手等工具集成到LED显示屏单元上，拼装时无需另外携带工具，一定程度上优化了拼装流程，但没有根本性的性能提升。
3、拉动锁
箱体拉动锁采用螺纹锁固的方式，长期使用变形量小，锁固精度比较稳定，但操作复杂，需“先将拉杆推进另一块屏体后，旋转90°，再将中部锁固大螺母拧紧”，步骤繁琐，松扣时还存在锁固过紧导致的不易松扣问题。
4、改进型拉动锁
改进型拉动锁将传统拉动锁锁固用的大螺母改进为扳手式样，且通过调整牙距等方式，简化了锁固所需的行程，解决了不易松扣的问题，但仍需“先把拉杆推进另一块屏并旋转90°，再将中部锁固大螺母拧紧”这个步骤，操作还是很繁琐。
5、预固定型拉动锁
这种锁扣利用一个滑动卡板，可以实现吊装时预固定，适用于LED显示屏的吊装方式，但预固定好后需腾出手，再使用随身携带的工具进行下一步安装，过程繁琐。
以上几种锁固机构为现有技术中的几种LED显示屏单元锁固方式，均存在操作繁琐、需换手操作、单人拼装困难、稳定性不高、费时费力、效率不高等问题，单元屏体之间的定位需依靠另外加装定位销，拼缝间隙难以控制，组装后的显示屏不便于拆卸，传统的拼装结构尤其不适用于对拼缝精度要求较高的高分辨率显示屏，给大面积的租赁显示屏安装造成了烦恼。

具体实施方式
下面结合附图以及实施方式对本发明进行进一步的描述：
如图1-3所示，一种快速锁固机构，包括第一连接部25和第二连接部26。
第一连接部25包括第一安装位7、固定基座9、旋转把手11、运动销轴12以及限位卡簧10，固定基座9固定在第一安装位7上，固定基座9通过螺旋结构与旋转把手11连接，通过旋转把手11和固定基座9之间的螺纹旋转，带动运动销轴12上下运动，达到锁紧与松扣的目的。限位卡簧10设于固定基座9和旋转把手11之间，运动销轴12中部设有卡簧安装槽16，其前端设有止锁板卡槽14，运动销轴12前端依次穿过旋转把手11和固定基座9，并且伸出第一安装位7，运动销轴12卡在第一安装位7上，限位卡簧10卡在卡簧安装槽16上，上下限位于旋转把手11中。
旋转把手11的端面上设有旋转定位孔20，运动销轴12的末端设有与旋转定位孔20相匹配的限位球头柱塞13。优选的，旋转定位孔20为4个，限位球头柱塞13为2个。通过运动销轴12上的两个限位球头柱塞13与旋转把手11底部的旋转定位孔20的配合，达到弹珠弹起发出声音，进而提示判断锁紧或松扣。
第一安装位上7设有限位螺钉8，限位螺钉8插入运动销轴12上的限制旋转槽15内，限制运动销轴12的左右旋转。
第二连接部26包括第二安装位6，止锁板4、止锁扳手5、扭簧2以及盖板1，止锁板4上设有相连的止锁孔21和分离孔22，盖板1上设有凸出的止锁板旋转轴17，止锁板4通过设于其上的旋转孔23压住扭簧2并套在止锁板旋转轴17上，并实现扭簧2的安装固定。通过止锁板手5带动止锁板4围绕旋转孔23旋转，达到分离孔22与止锁孔21的切换功能，通过止锁板4上止锁孔21与分离孔22的横向运动，达到与运动销轴12的卡住和松开的目的。止锁扳手5通过 螺钉3固定在止锁板4的一端，止锁板4和扭簧2设于盖板1上并沿盖板1旋转，盖板1压住扭簧2和止锁板4与第二安装位6固定，通过止锁板4上扭簧2的弹性复位功能，达到预固定时止锁板4的回弹。第二安装位6与第一安装位7相匹配，且第二安装位6上设有运动销轴导入锥孔19。
盖板1内侧设有球面顶销18，盖板1通过球面顶销18压住止锁板4的一侧，防止止锁板4的不良翘起。
如图4所示，一种设有快速锁固机构的LED组合屏，包括若干个LED单元屏24，第一LED单元屏上设有一个或以上的第一连接部25，与第一LED单元屏连接的第二LED单元屏上设有与第一连接部25相对应的第二连接部26。
第一连接部25设于第一LED单元屏的上端，且第一连接部25上的运动销轴12伸出第一LED单元屏的上沿，第二连接部26设于第二LED单元屏的下端。
本发明的工作原理为：
在锁紧过程中，用手握住旋转把手11，将LED单元屏举起，将运动销轴12对准第二安装位6的运动销轴导入锥孔19并插入孔内，此时运动销轴12顶部的斜面推动止锁板4上的止锁孔21，使止锁板4围绕旋转孔23开始旋转，当插入到一定深度，运动销轴12端部完全进入分离孔22时，止锁板4在扭簧2的复位弹力带动下回弹，使止锁孔21卡在运动销轴12的止锁板卡槽14上，同时发出回弹声音，完成LED单元屏的预固定。
此时再用手旋转旋转把手11，旋转把手11与固定基座9之间的螺纹，会带动旋转把手11向下运动，进而压迫运动销轴12向下运动。运动销轴12上的止锁板卡槽14与止锁板4之间的间隙缩小直至为零，同时运动销轴12上的两颗限位球头柱塞13滑入旋转把手12底部的旋转定位孔20内，发出弹珠声音提示装 置已锁紧。达到将第一连接部25和第二连接部26锁紧的目的。
在松扣过程中，手握住旋转把手11，反向旋转该把手11，旋转把手11与固定基座9之间的螺纹，会带动旋转把手11向上运动，由于有限位卡簧10的存在，进而带动运动销轴12向上运动，运动销轴12上的止锁板卡槽14与止锁板4之间的间隙增大，同时运动销轴12上的两颗限位球头柱塞13滑入旋转把手11底部的旋转另外两个旋转定位孔20内，发出弹珠声音提示装置已松脱。
再用大拇指拨动止锁扳手5，由于运动销轴12上的止锁板卡槽14与止锁板4之间的间隙增大，拇指可以带动止锁板4围绕止锁板旋转轴17转动，使止锁孔21与运动销轴12上的止锁板卡槽14逐渐脱离，当达到分离孔位置时，运动销轴12可完全脱离止锁板4，并从第二安装部26的运动销轴导入锥孔19中脱出，此时止锁板4在扭簧2弹力作用下回弹原位，达到将第一连接部25和第二连接部26松扣的目的。
应当理解的是，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本发明所附权利要求的保护范围。
上面结合附图对本发明专利进行了示例性的描述，显然本发明专利的实现并不受上述方式的限制，只要采用了本发明专利的方法构思和技术方案进行的各种改进，或未经改进将本发明专利的构思和技术方案直接应用于其它场合的，均在本发明的保护范围内。
