具体地，如图2及图3所示，第一长连杆架体2321、第二长连杆架体2322、第一短连杆架体2323及第二短连杆架体2324均包括两相对设置的连杆件。斜面的第一边与斜面的第二边相对平行设置，支撑底板的第一边与支撑底板的第二边相对平行设置，且支撑底板的第一边比支撑底板的第二边更靠近斜面的第一边。第一长连杆架体2321的中部与第二长连杆架体2322的中部之间交错设置，且两者之间通过一长销轴21进行转动连接。第一长连杆架体2321的一端通过一长销轴21与斜面的第一边进行转动连接，第一长连杆架体2321的另一端通过两短销轴22与第一短连杆架体2323的一端进行转动连接，第一短连杆架体2323的另一端通过一长销轴21与支撑底板的第二边进行转动连接。第二长连杆架体2322的一端通过一长销轴21与支撑底板的第一边进行转动连接，第二长连杆架体2322的另一端通过两短销轴22与第二短连杆架体2324的一端进行转动连接，第二短连杆架体2324的另一端通过一长销轴21与斜面的第二边进行转动连接。
如图3所示，支撑件2311还包括两相对紧固于支撑底板两侧的三角侧板，每一三角侧板邻近支撑底板一侧的侧边设有两销轴孔，以对应安装支撑底板的第一边的长销轴以及支撑底板的第二边的长销轴，使得第一短连杆架体2323的另一端通过一长销轴21与支撑底板的第二边进行转动连接，第二长连杆架体2322的一端通过一长销轴21与支撑底板的第一边进行转动连接。第二座体220远离支撑底板的一侧设有把手转轴221。调节控件2312包括绕把手转轴221转动的调节把手23121、在调节把手23121驱使下带动支撑件2311转动的钢丝边框23122以及驱使调节把手23121转动后固定的扭簧23123。钢丝边框23122环设于支撑件2311与第二座体220的四周，以紧固连接支撑件2311与第二座体220。为使调节把手23121扳动时有顿挫感，可在调节把手23121的连接处安装玻珠螺丝。还有，调节控件2312还包括调节钢丝边框23122的长度的调节螺母23124，以通过调节螺母23124调节钢丝边框23122的长度，使得支撑件2311与第二座体220的连接紧固可靠，进而使得两个LED箱体之间的连接紧固可靠。
另外，如图2及图3所示，该弧度锁扣200还包括数显模块240，该数显模块240为一容栅结构，具体包括定栅安装架、定栅、容栅检测器盖、动栅固定架、动栅模块以及限位螺丝，定栅安装架安设于第一长连杆架体2321与第一短连杆架体2323之间的连接处，动栅固定架安设于第二长连杆架体2322与第二短连杆架体2324之间的连接处，动栅模块安设于动栅固定架上形成定栅插接滑槽，且容栅检测器盖盖设动栅模块，定栅安设于定栅安装架上，且与定栅插接滑槽插接连接，限位螺丝锁紧动栅模块的一侧，以防止动栅模块脱落。这样一来，通过该容栅结构通过将动栅模块2315和定栅2312之间的电容变化（由于弧度运动时，两个连接处之间的距离发生改变，使得动栅模块2315和定栅2312之间的电容亦发生变化）转换成数值显示出来，来达到检测角度的目的，可使得角度精度达到0.1度，使用起来更简单。
这样一来，便可通过按下扭簧23123上的按键，使得扭簧23123发生形变，进而使得调节把手2312解除锁紧状态，然后，扳动调节把手23121，使得钢丝边框23122转动，以带动支撑件2311转动，从而驱使多连杆机构232的各连接处进行相对转动，使得支撑底板212带着第二座体220沿着如图4所示的虚线轨迹相对第一座体210的斜面进行弧线运动，使得两相邻LED箱体100之间可进行大范围角度调节，即既可如图5所示，进行内弧度拼接，亦可如图6所示进行外弧度拼接。当调节到相应角度时，松开扭簧23123上的按键，使得扭簧23123弹性复位，使得调节把手2312重新进入锁紧状态，便可完成相应的弧度调节。
对于本领域技术人员而言，本实施例中的数显模块240亦可为其它带刻度且可进行精准调节的结构，如光栅尺调节件、磁栅尺调节件等等。同时，本实施例通过销轴进行转动连接，亦可采用铆接、轴承等结构进行替代。
以上结合附图对本申请的实施方式作了详细说明，但本申请不限于所描述的实施方式。对于本领域的技术人员而言，在不脱离本申请原理和精神的情况下，对这些实施方式进行多种变化、修改、替换和变型，仍落入本申请的保护范围内。
 工业实用性
本申请提供的弧度锁扣及带该弧度锁扣的LED显示屏，其弧度锁扣包括第一座体、第二座体以及角度调节锁紧组件，其中，角度调节锁紧组件包括转动锁紧机构以及通过转动锁紧机构驱使第二座体相对第一座体的斜面进行弧线运动的多连杆机构，转动锁紧机构包括支撑件以及驱使支撑件转动及转动后锁紧的调节控件。这样一来，当LED显示屏的两两LED箱体之间通过至少一弧度锁扣进行紧固连接时，便可通过调节控件控制支撑件转动，进而驱使多连杆机构的各连接处进行相对转动，使得一LED箱体随着支撑底板相对另一相邻的LED箱体进行弧线运动，进而达到调节两相邻LED箱体之间的夹角角度的目的，结构简单且不存在切线方向上的误差。同时，通过调节控件进行转动调节，使用起来更简单方便。因此，具有工业实用性。
