本发明涉及显示器技术领域，尤其涉及一种LED显示屏箱体锁扣结构。

 技术问题
有鉴于此，本发明的目的在于提供一种LED显示屏箱体锁扣结构，通过曲面导轨将调整块的直线运动转变为角度块的旋转运动，实现角度调节，提高了角度拼接精度，且结构简单、操作方便，不需要机械加工，大幅度降低了成本。

 本发明的实施方式
为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚、明白，以下结合附图和实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
实施例
如图1所示，为本发明LED显示屏箱体锁扣结构的爆炸示意图，图2为本发明LED显示屏箱体锁扣结构的组合图，图3为一种LED显示屏箱体锁扣结构的正视图，图4为图3中的A-A剖视图，图5为图3中的B-B剖视图；在本实施例中，一种LED显示屏箱体锁扣结构，包括：调整块2、角度块3和曲面导轨14，所述调整块2、角度块3和曲面导轨14皆设置在箱体1上，所述调整块2通过曲面导轨14与所述角度块3连接，当所述调整块2直线运动时，通过所述曲面导轨14驱动所述角度块3旋转运动。
在本实施例中，通过曲面导轨14将调整块2的直线运动转变为角度块3的旋转运动，实现角度调节，提高了角度拼接精度，且结构简单、操作方便，不需要机械加工，大幅度降低了成本。
从图5可以看出，所述调整块2通过曲面导轨14与所述角度块3连接；当调整块2沿着弧度调节螺杆6的轴向做直线运动时，通过曲面导轨14带动角度块沿着垂直于所述轴向的方向朝箱体外部做旋转运动。
在本实施例中，所述曲面导轨14和显示屏的角度调节方向呈90°角设置，此时导轨的间隙误差不会放大到显示屏的拼接精度上，极大地提高了显示屏的拼接精度，其中，显示屏的角度调节方向可以参考图7、图8及图9所示。
在本实施例中，所述箱体1上还设置有锁扣锁紧结构4，所述锁扣锁紧结构4与所述角度块3对应设置，一个箱体1上的角度块3与另一个箱体1上的锁扣锁紧结构4相配合，进行两个箱体1之间的角度调节。
如图3及图5所示，所述锁扣锁紧结构4包括手柄41和手柄41上活动连接的连接杆42，参考图7-图9，连接杆42用于与另一个箱体1的角度块3连接，当所述角度块3做旋转运动时，通过连接杆42的支撑作用，两个箱体1之间实现角度调节。
在本发明的一个实施方式中，如图5所示，角度块3包括第一端和第二端，调整块2的卡设端通过曲面导轨14卡设于角度块3的第一端，角度块3的第二端上具有挂孔，锁扣锁紧结构4中的连接杆42的用于连接角度块3的一端为十字形结构，可通过转动锁扣锁紧结构4中手柄41而使得连接杆42旋转，可旋转的连接杆42配合角度块3的第二端上的挂孔而与角度块3进行连接。当角度块3的第二端位于箱体内时，调整块2的卡设端位于曲面导轨14的最低端（该最低端与角度块3的第二端的距离相对于曲面导轨14的其它部分与角度块3的第二端的距离更近），当角度块3的第二端旋转至箱体外且行程到达最大限度时，调整块2的卡设端位于曲面导轨14的最高端（该最高端与角度块3的第二端的距离相对于曲面导轨14的其它部分与角度块3的第二端的距离更远）。
在本实施例中，所述箱体1上还设置有弧度调节手轮5和弧度调节螺杆6，所述弧度调节手轮5与所述弧度调节螺杆6的一端连接，所述调整块2上设置有内螺孔，所述弧度调节螺杆6与所述调整块2螺接，通过所述弧度调节手轮5使所述调整块2沿着所述弧度调节螺杆6的方向直线运动。
在本实施例中，所述弧度调节螺杆6的另一端设置有弧度调节螺杆固定套7（可见图1）。
在本实施例中，所述弧度调节手轮5上设置有手轮波珠8（可见图1），所述手轮波珠8的定位角度为36度；也就是将旋转一圈分为10等分，这就使得调整精度放大了10倍，转一圈手轮为1度，一个波珠定位点的调整量为0.1度。
作为另一种实施例，所述手轮波珠8的定位角度可以按照用户需求自行设置，比如18度或72度。
在本实施例中，所述箱体1上还设置有滑轨9，所述调整块2在所述滑轨9上做直线运动。
如图6所示，在本实施例中，所述调整块2的外部设置有弧度刻度盖板10，用于指示所述调整块2的调整度。
在本实施例中，所述弧度刻度盖板10上设置有游标式角度调节按钮11；在不是用弧度调节手轮5进行调节时，可以通过上下推动该角度调节按钮11进行调节，当使用弧度调节手轮5进行调节时，该角度调节按钮11仅用于指示刻度的作用，弧度刻度盖板10上的刻度一格为1度，角度调节按钮11上的一个刻度为弧度刻度盖板10上一格的0.9倍，所以当角度调节按钮11移动0.1度的时候角度调节按钮11上的1刻度即对准弧度刻度盖板10上的一个格线，从而指示0.1度，读数方法是，弧度刻度盖板10上的格线和角度调节按钮11上的0位对准的是度数值，角度调节按钮11上的刻度和弧度刻度盖板10上的刻度对准的为小数角度值。
在本实施例中，所述调整块2的数量为两个，两个调整块2均匀设置于所述箱体1的需要调节角度的边缘处；所述箱体1为长方形，两个调整块2分别位于箱体1需要调节角度的一个矩形边的两端，相应地，与该矩形边平行的另一个矩形边的两端设置有两个锁扣锁紧结构4。
在本实施例中，所述角度块3和所述锁扣锁紧结构4的数量也为两个，并与所述调整块2对应设置。
如图7-图9所示，为两个显示屏拼接示意图，包括第一显示屏12和第二显示屏13，其中，图7为两个显示屏角度为180度时的拼接示意图，图8为两个显示屏内弧度拼接时的拼接示意图，图9为两个显示屏外弧度拼接时的拼接示意图。
 
以上参照附图说明了本发明的优选实施例，并非因此局限本发明的权利范围。本领域技术人员不脱离本发明的范围和实质内所作的任何修改、等同替换和改进，均应在本发明的权利范围之内。
 工业实用性
本发明实施例的一种LED显示屏箱体锁扣结构，通过将所述调整块、角度块和曲面导轨皆设置在箱体上，所述调整块通过曲面导轨与所述角度块连接，当所述调整块直线运动时，通过所述曲面导轨驱动所述角度块旋转运动；所述箱体上还设置有锁扣锁紧结构，所述锁扣锁紧结构与所述角度块对应设置，一个箱体上的角度块与另一个箱体上的锁扣锁紧结构相配合，进行两个箱体之间的角度调节，通过曲面导轨将调整块的直线运动转变为角度块的旋转运动，实现角度调节，提高了箱体间的角度拼接精度，且结构简单、操作方便，不需要机械加工，大幅度降低了成本。因此，具有工业实用性。
