具体实施方式
下面结合附图对本发明的具体实施方式作进一步说明。在此需要说明的是，对于这些实施方式的说明用于帮助理解本发明，但并不构成对本发明的限定。此外，下面所描述的本发明各个实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互组合。
实施例一
如图1及图2所示，本发明实施例一提供一种弧形调节锁100，该弧形调节锁100包括基座110、调节件120、按压锁组件130以及快锁组件140，基座110连接于相互拼接的第一LED箱体1上，基座110具有第一弧形部111，调节件120通过快锁组件140连接于相互拼接的第二LED箱体2上，调节件120具有与第一弧形部111相贴合的第二弧形部121，第一弧形部111与第二弧形部121之间通过错位双V型槽组150与两弹性玻珠160进行弧形滑动配合，且第一 弧形部111与第二弧形部121之间通过按压锁组件130实现弧形滑动后的锁定操作。
在本实施例中，如图2所示，错位双V型槽组150设于第一弧形部111靠近第二弧形部121的一侧，两弹性玻珠160分别安设于第二弧形部121。具体地，错位双V型槽组150包括与一弹性玻珠160进行弧形滑动配合的第一V型槽组151以及与另一弹性玻珠160进行弧形滑动配合的第二V型槽组152，第二V型槽组152位于第一V型槽组151的延伸方向上。第一V型槽组151包括沿第一弧形部111的延伸方向依次并排设置的若干第一V型槽1511，相邻的第一V型槽1511之间设置有第一过渡槽1512，第一V型槽1511的深度大于第一过渡槽1512的深度，第二V型槽组152包括沿第一弧形部111延伸方向依次并排设置的若干第二V型槽1521，相邻的第二V型槽1521之间设置有第二过渡槽1522，第二V型槽1521的深度大于第二过渡槽1522的深度。每段V形槽(即第一V型槽组151或第二V型槽组152)为2.5度一刻，错位1.25度，可实现1.25度角度调节。当一个弹性玻珠160位于第一V型槽1511或第二V型槽1521中时，另一个弹性玻珠160位于第二过渡槽1522或第一过渡槽1512中
如图2所示，第二弧形部121上设置有两玻珠安装槽(未图示)，两弹性玻珠160一一对应安设于两玻珠安装槽上。具体地，弹性玻珠160包括玻珠主体161以及第一弹簧162，第一弹簧162抵接在玻珠主体161与玻珠安装槽的底壁之间。第二弧形部121的一侧还设置有弧形导向槽(未图示)，弧形导向槽的延伸方向与第二弧形部121的延伸方向相同，基座110的一侧安设有与弧形导向槽相适配的弧形导向块112，其可在第二弧形部121相对第一弧形部111之间进行弧形滑动时起到一定的导向限位作用。第二弧形部121与第一弧形部111之间还通过弧形导向块112与弧形导向槽进行弧形滑动配合。
如图1及图2所示，第一弧形部111远离第二弧形部121的一侧还设置有带刻度线的弧形槽孔1111，当显示刻度为1.25度时，与第二V型槽组152相对应的弹性玻珠160位于0度到2.5度之间的1.25度中间位置，即位于第二过渡槽1522中，与第一V型槽组151相对应的弹性玻珠160卡入第一V形槽1511中，实现1.25度角度限位，第二弧形部121对应弧形槽孔1111处设置有按压锁组件安装槽(图中未标示)，按压锁组件130穿过弧形槽孔1111安设于按压锁组件安装槽中,以在第二弧形部121与第一弧形部111之间实现弧形滑动后的锁定操作。具体地，弧形槽孔1111的两侧设有两弧块113，且每一弧块113的表面设有延其延伸方向的第一锯齿1131。按压锁组件130包括手柄转轴131、第二弹簧132、T型按压块133以及按压手柄134，手柄转轴131的固定端穿过弧形槽孔1111固设于按压锁组件安装槽的底端，手柄转轴131的铰接端依次套设有第二弹簧132与T型按压块133，且手柄转轴131的铰接端还铰接有按压手柄134，按压手柄134铰接手柄转轴131的一端还与T型按压块133的外侧抵接连接，T型按压块133的内侧设有与每一弧块113的第一锯齿1131相啮合的第二锯齿1331。这样一来，当按压手柄134向下压，使得T型按压块133内侧的第二锯齿1331与每一弧块113的第一锯齿1131相啮合，此时整体处于压紧状态，而当按压手柄134向上旋转，则T型按压块133在第二弹簧132的弹性复位作用下向上弹起，使得T型按压块133内侧的第二锯齿1331与每一弧块113的第一锯齿1131分离。
如图1及图2所示，第二弧形部121的一端为直板安装面1211，直板安装面1211设置有锁孔1212，快锁组件140包括安设于第二LED箱体2上的锁芯转轴141、驱使锁芯转轴141转动的带把手的转轴套142以及驱使锁芯转轴141复位的第三弹簧143。当沿水平方向将锁芯转轴141推进锁孔1212中，同时旋转 90度即可将直板安装面1211与第二LED箱体2进行锁紧，进而实现相邻的第一LED箱体1与第二LED箱体2之间的锁紧。另外，直板安装面1211与第二LED箱体2相接的一侧表面设有限位凸起部1213，以与第二LED箱体2上设置的限位凹槽(未图示)进行限位配合，间隙只有0.1mm,保证箱体不会前后上下错位。
实施例二
如图3及图4所示，本发明实施例二提供一种弧形调节锁200，与实施例一的弧形调节锁100相比，其区别在于，本实施例的错位双V型槽组250设于第二弧形部221面向第一弧形部211的一侧表面上，两弹性玻珠260分别安设于第一弧形部211上。具体地，错位双V型槽组250包括与一弹性玻珠260进行弧形滑动配合的第一V型槽组(未标示)以及与另一弹性玻珠260进行弧形滑动配合的第二V型槽组252，第一V型槽组包括若干沿第二弧形部221延伸方向依次并排设置的多个第一V型槽2511，相邻的第一V型槽2511之间设置有第一过渡槽2512，第一V型槽2511的深度大于第一过渡槽2512的深度，第二V型槽组252包括若干沿第二弧形部221延伸方向依次并排设置的多个第二V型槽2521，相邻的第二V型槽2521之间设置有第二过渡槽2522，第二V型槽2521的深度大于第二过渡槽2522的深度。每段V形槽(即第一V型槽组或第二V型槽组252)为2.5度一刻，错位1.25度，可实现1.25度角度调节。当一个弹性玻珠160位于第一V型槽2511或第二V型槽2521中时，另一个弹性玻珠160位于第二过渡槽2522或第一过渡槽2512中
如图3及图4所示，第一弧形部211上设置有两玻珠安装槽2111，两弹性玻珠260一一对应安设于两玻珠安装槽2111上。具体地，弹性玻珠260包括玻珠主体261以及第一弹簧262，第一弹簧262抵接在玻珠主体261与玻珠安装槽2111的底壁之间。第二弧形部221的一侧还设置有弧形导向槽孔(未图示)，弧 形导向槽孔的延伸方向与第二弧形部221的延伸方向相同，基座210的一侧安设有与弧形导向槽孔相适配的弧形导向块212，其可在第二弧形部221相对第一弧形部211之间进行弧形滑动时起到一定的导向限位作用，第二弧形部221与第一弧形部211之间还通过弧形导向块212与弧形导向槽孔进行弧形滑动配合。
如图3及图4所示，调节件220还包括位于第二弧形部221一端的直板部222，直板部222设置有锁孔2221，快锁组件240包括安设于第二LED箱体2上的锁芯转轴(未标示)、驱使锁芯转轴转动的带把手的转轴套(未标示)以及驱使锁芯转轴复位的第三弹簧(未图示)。当沿水平方向将锁芯转轴推进锁孔2221中，同时旋转90度即可将直板部222与第二LED箱体2进行锁紧，进而实现相邻的第一LED箱体1与第二LED箱体2之间的锁紧。另外，直板部222与第二LED箱体2相接的一侧表面设有限位凸起部2222，以与第二LED箱体2上设置的限位凹槽(未图示)进行限位配合，间隙只有0.1mm,保证箱体不会前后上下错位。
本发明实施例提供的弧形调节锁，其包括基座、调节件、按压锁组件以及快锁组件，基座具有第一弧形部，调节件具有与第一弧形部相贴合的第二弧形部，第一弧形部与第二弧形部之间通过错位双V型槽组与两弹性玻珠进行弧形滑动配合，且第一弧形部与第二弧形部之间通过按压锁组件实现弧形滑动后的锁定操作。使用时，基座连接于相互拼接的第一LED箱体上，调节件通过快锁组件连接于相互拼接的第二LED箱体上，此时，通过错位双V型槽组与两弹性玻珠进行弧形滑动配合，使得调节件的第二弧形部沿基座的第一弧形部进行弧形滑动，最后再通过按压锁组件实现弧形滑动后的锁定操作，便可实现LED显示屏的两个相邻的LED箱体之间的弧形运用及安装操作，同时，通过错位双V型槽组与两弹性玻珠进行弧形滑动配合，可实现更小角度的弧度调节。
以上结合附图对本发明的实施方式作了详细说明，但本发明不限于所描述的实施方式。对于本领域的技术人员而言，在不脱离本发明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，仍落入本发明的保护范围内。
