Abstract

The invention discloses a screen floating device which comprises at least two supporting frames, and the supporting frames are respectively arranged at the two sides of a back-projecting box and fixedly connected with the two sides of a screen; and the supporting frames are respectively provided with a rotating unit, the rotating unit comprises a rotating shaft and a hook, the rotating shaft is arranged on the back-projecting box, and the hook is arranged at the rotating shaft and fixedly connected with the screen. By using the screen floating device disclosed by the invention, two adjacent screens can be mutually tightly combined, so that the minimization of an edge joint between the screens is realized, and then the effect that the edge joint is less than 0.5 mm is achieved. When pluralities of screens are fixed together by using spring nails for clamping, the situation that the edge joints are always minimized can be ensured without being affected by manufacturing tolerances or climatic changes.

Description

technical field [0001] The invention relates to the technical field of screen assembling, in particular to a screen floating device. Background technique [0002] In practical applications, the large screen of a multi-screen display device is generally assembled from many small screens or screens, such as figure 1 or figure 2 shown. figure 1 Shown is the front structure of a commonly used multi-screen display device, figure 2 Shown is the side structure of a commonly used multi-screen display device, which is composed of M screens in the horizontal direction and N screens in the vertical direction, and some may be equipped with a base at the bottom. In the figure, 1 is a seam, 2 is a single small screen, and 3 is a base. It can be seen from the figure that a support mechanism 4 and a projector 5 are respectively arranged behind the small screen, and the support mechanism 4 can be a corresponding to each small screen. One or more small screens correspond to one or a lar...
