如图9所示，所述旋转件4上设有玻珠螺栓41。如图10所示，所述壳体22上分别设有与所述玻珠螺栓41相配合的第一限位部224和第二限位部225。所述壳体22靠近箱体1的一侧面上还设有至少两个的定位件226，所述箱体1上设有至少两个的与所述定位件226相配合的定位孔。
当需要对显示屏模组2进行前维护时，可以通过磁性联轴器8带动磁性件7转动，从而带动固定件3转动，固定件3带动锁定件5作直线运动从而使第一锁定部52和第二锁定部11相互分离，实现箱体1与显示屏模组2之间的拆卸；当需要对显示屏模组2进行后维护时，通过旋转件4带动固定件3转动，固定件3带动锁定件5作直线运动从而使第一锁定部52和第二锁定部11相互分离，实现箱体1与显示屏模组2之间的拆卸。当需要将显示屏模组2与箱体1进行固定时，只需要先通过定位件226和定位孔相互配合进行定位，然后向与拆卸时相反的方向转动固定件3，即可使第一锁定部52和第二锁定部11相互锁定。
本实用新型的实施例二为：
一种显示屏模组，与实施例一的不同之处在于：不设置箱体，将显示屏模组单独使用，在显示屏模组的待安装位置上设置与第一锁定部相配合的第二锁定部。
综上所述，本实用新型提供的一种固定装置、显示屏模组及显示屏，固定装置结构简单，安装所述固定装置的显示屏模组可以进行前后维护，操作方便，可大大降低维护成本。
以上所述仅为本实用新型的实施例，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等同变换，或直接或间接运用在相关的技术领域，均同理包括在本实用新型的专利保护范围内。
