[0002] Holographic projection technology belongs to one kind of 3D technology, and originally refers to the technology for recording and reproducing the real three-dimensional image of an object. Then, with the guidance of science fiction movies and commercial promotion, the concept of holographic projection is gradually extended to commercial activities such as stage performances and exhibition displays. At present, on the market, holographic projection technology is to tilt the holographic film to 45 degrees, and the projection can be transmitted through the bottom or top of the device, and then refracted on the film. For example, Chinese patent CN201621404918.3 discloses a holographic imaging system, which includes a bracket suspended, a frame provided with a holographic film, a first driving mechanism provided on the bracket, a flat device and a second driving mechanism. The first edge frame of the frame is hinged to the bracket. The first driving mechanism is suitable for lifting the second edge frame on the frame relative to the first edge frame. The flat device is horizontally arranged and displays a picture to the holographic film below. The second driving mechanism is suitable for lifting the flat device. The imaging system has the hidden danger of unstable clamping of the holographic film, and the stability of the holographic film is not high. SUMMARY

[0004] A naked eye 3D holographic film's clamping frame, which includes a frame body, four L-shaped steel plates arranged on the four sides of the frame body, and four pressing assembly components arranged on one side of each of the four L-shaped steel plates. The pressing assembly component includes a plurality of U-shaped plates arranged in a row, an upper pressing plate arranged inside the U-shaped plate, a lower pressing plate arranged on one side of the upper pressing plate, and a plurality of pressing screws corresponding to the plurality of U-shaped plates.

[0005] Further, the frame body is a rectangular square frame formed by connecting four square tubes end to end, and a side wall cover is welded to the outer side wall of the frame body.

[0006] Further, one side wall of the L-shaped steel plate is welded to the frame body.

[0009] Furthermore, the upper pressure plate and the lower pressure plate are hollow inside.

[0010] Compared with existing technologies, the clamping frame of the naked-eye 3D holographic film provided by this utility model controls the clamping force between the upper and lower pressure plates through the relative rotation between the pressure screws and the pressure nuts, thereby clamping the holographic film. The upper and lower pressure plates 32 and 33 can be hidden inside the U-shaped plate 31, saving more space, reducing the thickness of the frame, and increasing the display area.

[0014] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0015] like Figure 1 The diagram shows a structural schematic of the clamping frame for the naked-eye 3D holographic film provided by this utility model. The clamping frame includes a frame body 10, four L-shaped steel plates 20 respectively disposed on the four sides of the frame body 10, and four pressing assemblies 30 respectively disposed on one side of the four L-shaped steel plates 20. It is conceivable that the clamping frame for the naked-eye 3D holographic film also includes other functional modules, such as a welding module and a screw module, which are technologies well known to those skilled in the art and will not be described in detail here.

[0016] The frame body 10 is a rectangular frame formed by connecting four square tubes end to end, and a side wall cover 11 is welded to the outer side wall of the frame body 10. The L-shaped steel plate 20 and the press-fit assembly 30 are accommodated in the side wall cover 11 to protect them from external impact and prolong their service life.

[0017] Please refer to Figure 2 With Figure 3 One side wall of the L-shaped steel plate 20 is welded to the frame body 10 and located inside the side wall cover 11. The L-shaped steel plate 20 is used to mount the press-fit assembly 30 to fix the press-fit assembly 30, so that the press-fit positions of the four press-fit assemblies 30 are arranged correspondingly to each other, thereby pressing four sides of a holographic film.

[0018] The press-fit assembly 30 includes a plurality of U-shaped plates 31 arranged in a line, an upper pressing plate 32 arranged inside the U-shaped plate 31, a lower pressing plate 33 arranged on one side of the upper pressing plate 32, and a plurality of press-fit screws 34 arranged correspondingly to the plurality of U-shaped plates 31.

[0019] The plurality of U-shaped plates 31 are arranged in a line on the L-shaped steel plate 20 to ensure balanced force, and the U-shaped plate 31 is fixedly connected to one side wall of the L-shaped steel plate 20 through screws and nuts. The two inner side walls of the U-shaped plate 31 abut against the opposite two side walls of the upper and lower pressing plates 32, 33, respectively, to arrange the upper and lower pressing plates 32, 33 and hide them in the U-shaped plate 31, thereby saving space, reducing the thickness of the frame, and improving the display area. According to test data, the display area of a traditional frame is 5310mm*3020mm, and the display area of the naked-eye 3D holographic film clamping frame is 5810mm*3520mm, which is more than 27.5% larger than that of the traditional frame.

[0020] The upper and lower pressing plates 32, 33 are hollow inside to reduce the overall weight of the frame and facilitate transportation and installation. The hollow upper and lower pressing plates 32, 33 can slightly deform when clamping the holographic film, thereby more stably clamping the holographic film and improving the stability of the holographic film.

[0021] The opposite sides of the upper and lower pressing plates 32, 33 respectively have an anti-slip layer 35 made of high-friction materials such as diamond sand and rubber. The two anti-slip layers 35 clamp the holographic film to prevent it from shifting or falling due to external factors and to avoid image distortion caused by sliding, thereby improving the stability of the holographic film.

[0022] The press screw 34 penetrates two side walls of the U-shaped plate 31 and the upper and lower press plates 32, 33, two anti-skid layers 35 and a holographic film, and a press nut 36 is arranged at the tail of the press screw 34, so that the pressing force between the upper and lower press plates 32, 33 is controlled through the relative rotation between the press screw 34 and the press nut 36, so as to achieve the purpose of clamping the edge of the holographic film. It is conceived that the edge of the holographic film is correspondingly provided with a plurality of through holes for penetrating the press screw 34.

[0023] Compared with the prior art, the clamping frame of the naked eye 3D holographic film provided by the utility model controls the pressing force between the upper and lower press plates 32, 33 through the relative rotation between the press screw 34 and the press nut 36 to clamp the holographic film. The upper and lower press plates 32, 33 can be hidden in the U-shaped plate 31, so that the space is saved, the thickness of the frame is reduced, the display area is improved, and the display area of the clamping frame of the naked eye 3D holographic film is increased by more than 27.5% compared with the traditional frame. And the anti-skid layer 35 can effectively prevent the holographic film from being displaced or falling off due to external force factors, avoid image distortion caused by sliding, and improve the stability of the holographic film.

[0024] The above is only the preferred embodiment of the utility model, and is not used for limiting the protection scope of the utility model, and any modification, equivalent replacement or improvement within the utility model spirit is covered in the claim range of the utility model.
