Description

Installation fixing device suitable for multiple types of display screen boxes and display screen Technical Field The utility model belongs to the technical field of display screens, and particularly relates to a mounting and fixing device suitable for multiple types of display screen boxes and a display screen. Background In the technical field of display screens, application scenes of arc-shaped and special-shaped display screens are increasingly wide, such as commercial display, immersive experience space, stage performance and the like, and flexibility and stability of splicing and installation of the arc-shaped and special-shaped display screens become technical difficulties. The traditional arc display screen connection scheme mainly has the following limitations: In the prior art, the arc-shaped display screen is often spliced by arranging a trimming edge on the connecting side of the box body frame and matching with an arc lock (such as the patent application with the application number of CN 202223488589.3). This scheme relies on the side cut angle of processing in advance, only can adapt to the concatenation demand of single radian, if need adjust arc camber or concatenation angle, need the customization side cut structure again, and the commonality is poor and with high costs. In addition, the special radian locking device is adopted to fix the adjacent box body, so that the production cost is high.
