Embodiment 1

[0037] In this embodiment, a screen floating device has a structure such as Figure 4 or Figure 5 As shown, at least two support frames are included, and each support frame is respectively arranged on both sides of the rear projection box 6 and is fixedly connected with both sides of the screen 2; each support frame is respectively provided with a rotating unit, such as Figure 7 As shown, the rotating unit includes a rotating shaft 7 and a rotating member 10 , the rotating shaft 7 is connected to the screen 2 through the rotating member 10 , and the rotating shaft 7 is connected to the rear projection box 6 through a shaft seat 13 .

[0038] In this example, if Figure 11 As shown, the rotating shaft 7 and the rotating member 10 are integrally constructed. The rotating member 10 is a fixed block fixed on the rotating shaft 7. As the rotating shaft 7 rotates, the rotating member 10 also rotates, thereby driving the screen 2 to rotate.

Abstract

The invention discloses a screen floating device which comprises at least two supporting frames, wherein the supporting frames are arranged on two sides of a rear-projection box respectively and fixedly connected with two sides of a screen; the supporting frames are provided with rotating units respectively; each rotating unit comprises a rotating shaft and a rotating piece; the rotating shaft is connected with the screen through the rotating piece; and the rotating shaft is connected with the rear-projection box through a shaft seat. By the screen floating device, two adjacent screens can be combined tightly; therefore, a joint between the screens is minimized and the size of the joint is less than 0.5 millimeters. A plurality of screens are fixed together by using spring nail components, so that the joints can be kept minimum and cannot be influenced by manufacturing tolerance or climatic change.

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 unit 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 screen, and 3 is a base. As can be seen from the figure, a support mechanism 4 and a projector 5 are respectively arranged behind the screen, wherein the support mechanism 4 can be one for each screen, Multiple screens correspond to one or a large screen composed of all screens share one.
