请参考图1-图8，本发明一实施例提供了一种锁头机构100，包括底座110、锁头件120和锁定组件130；锁头件120包括至少两个角度锁体121、与底座110转动连接的转体122，转体122与角度锁体121固定连接，转体122相对底座110转动以切换角度锁体121，角度锁体121用于供锁芯220呈角度锁紧连接；锁定组件130套设连接底座110与转体122之间，以用于将锁头件120锁定在底座110，或者解锁锁头件120。具体应用中，底座110与一块显示屏(图未示)固定连接，锁头件120通过转体122使得可以切换不同的角度锁体121，锁芯220的一侧与另一块显示屏固定连接，当角度锁体121与锁芯220呈角度连接时，此时两个显示屏形成一定的夹角，依次类推，当足够多的显示屏通过角度锁体121与锁芯220的拼接从而形成弧形曲面屏。另外，锁定组件130包括转动连接于底座110的手 柄131，与手柄131连接穿设于转体122与底座110之间的轴柱132，被配置为受手柄131转动按压的按压板133且该按压板133盖设于底座110上，位于按压板133与锁头件120之间用于限制锁头件120转动的波珠134，套设于轴柱132上的弹簧135，该锁定组件130通过操作手柄131从而控制波珠134来限制锁头件120相对底座110的转动，或者反向操作手柄131从而解除波珠134限制锁头件120的转动，此时，可以转动锁头件120切换不同的角度锁体121。
参照图1-3所示，在一种可能的实施方式中，锁头件120位于底座110上方，转体122径向向外延伸形成角度锁体121，每个角度锁体121远离转体122的一端形成有端面1211，至少有一个角度锁体121的端面1211朝偏离底座110方向设置，至少有一个角度锁体121的端面1211朝偏向底座110方向设置。具体应用中，角度锁体121的端面1211上设有锁孔1212，锁芯220通过锁孔1212与角度锁体121连接，从而实现不同的两块显示屏的角度连接。
参照图1-3所示，在一种可能的实施方式中，锁头件120包括有四个间隔设置的角度锁体121，其中，有两个角度锁体121的端面1211朝偏离底座110方向设置；有两个角度锁体121的端面1211朝偏向底座110方向设置。具体应用中，锁头件120向外延伸有四个间隔设置的角度锁体121，且两个角度锁体121的端面1211朝偏离底座110方向的角度不同，两个角度锁体121的端面1211朝偏向底座110方向的角度不同，从而使得锁头件120可以切换不同方向、偏离角度不同的角度锁体121，从而可以拼接形成不同弧形曲面需求的显示屏。
参照图1-3所示，在一种可能的实施方式中，角度锁体121还包括至少有一个角度锁体121的端面1211相对底座110水平方向设置。具体应用中，当角度锁体121的端面1211相对底座110水平方向设置时，可以使得两块显示屏实现平行拼接，因此，也可以满足直线平面屏拼接的实际需求。
参照图1-3所示，在一种可能的实施方式中，锁头件120包括有六个间隔设置的角度锁体121，其中，有两个角度锁体121的端面1211朝偏离底座110方向设置；有两个角度锁体121的端面1211朝偏向底座110方向设置；有两个角度 锁体121的端面1211相对底座110水平方向设置。具体应用中，锁头件120向外延伸有六个间隔设置的角度锁体121，且两个角度锁体121的端面1211朝偏离底座110方向的角度不同，两个角度锁体121的端面1211朝偏向底座110方向的角度不同，两个角度锁体121的端面1211相对底座110水平方向的角度均为0度，从而使得锁头件120可以切换不同方向、偏离角度不同的角度锁体121，也可以切换平行的角度锁体121，从而可以同时满足拼接形成不同弧形曲面和直线平面需求的显示屏，从而使得拼接显示屏更多样化。
参照图1和图4所示，在一种可能的实施方式中，端面1211朝偏离底座110方向设置为第一端面12111，第一端面12111与底座110的夹角为-6°至0°。具体应用中，图中第一端面12111底座110的夹角用a表示，第一端面12111与底座110的竖面111的夹角为-6°至0°之间，从而使得锁芯220相对的角度调节范围为-6°至0°之间，从而使得连接在底座110和锁芯220之间的底座110的每块显示屏的夹角为-6°至0°之间，可以满足不同显示屏拼接时对凹弧的曲率要求。
参照图1和图4所示，在一种可能的实施方式中，第一端面12111与底座110的夹角可分别为-6°和-3°。具体应用中，分别选取第一端面12111相对底座110竖面111的夹角为-6°和-3°的组合可以相对满足实际中对凹弧曲率的需求，当然，凹弧曲率的需求与每块显示屏的形状大小相关联，当每块显示屏的形状大小相对变化时，第一端面12111与底座110垂直方向的夹角也可以适当调整，因此，本领域技术人员在不付出创造性劳动成果下都应该认为是本发明所保护的技术内容。
参照图1和图5所示，在一种可能的实施方式中，端面1211朝偏向底座110方向设置为第二端面12112，第二端面12112与底座110的夹角为0°至6°。具体应用中，图中第二端面12112与底座110的夹角用b表示，第二端面12112与底座110的竖面111的夹角为0°至6°之间，从而使得锁芯220相对的角度调节范围为0°至6°之间，从而使得连接在底座110和锁芯220之间的底座110 的每块显示屏的夹角为0°至6°之间，可以满足不同显示屏拼接时对凸弧的曲率要求。
参照图1和图4所示，在一种可能的实施方式中，第二端面12112与底座110的夹角可分别为3°和6°。具体应用中，分别选取第一端面12111相对底座110垂面的夹角为3°和6°的组合可以相对满足实际中对凸弧曲率的需求，当然，凸弧曲率的需求与每块显示屏的形状大小相关联，当每块显示屏的形状大小相对变化时，第一端面12111与竖直面111的夹角也可以适当调整，因此，本领域技术人员在不付出创造性劳动成果下都应该认为是本发明所保护的技术内容。
参照图6-8所示，本发明二实施例提供一种锁紧装置10，包括上述的锁头机构100和用于锁紧锁头机构100的锁芯机构200；锁芯机构200包括壳体210、伸缩于壳体210的锁芯220、转动连接于壳体210用于驱动锁芯220运动的把手230、转动连接于壳体210用于解除限制锁芯220运动的按钮240；锁芯220与角度锁体121可锁紧连接。具体应用中，底座110与一块显示屏连接，壳体210与另一块显示屏连接，当锁芯220与角度锁体121的锁孔1212锁紧时，即可以把两块显示屏实现角度锁紧，在解锁时，通过按钮240解除壳体210对锁芯220的限制，可以防止锁芯220卡死。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
