Figure 2 is a sectional view of the whole of the first embodiment of the utility model, Figure 3 The utility model Figure 2 A magnified view of the local structure at A.

[0028] The utility model provides a holographic fan screen, including two fan screen display devices 101 and a mounting assembly, wherein the mounting assembly includes a base 102, a support seat 103, a plurality of fixed blocks 104, two limiting units, two buffer blocks 105, two buffer pads 106 and a plurality of moving wheels 109, the support seat 103 has two grooves 107, the two buffer pads 106 both have a groove body 108, the limiting unit includes a telescopic rod 110, a spring 111, a connecting plate 112 and a limiting rod 113, and the fan screen display device 101 has a limiting hole 114.

[0029] For this specific embodiment, the fan screen display device 101 performs a holographic 3D display. After use, the connecting plate 112 is pulled upward to drive the limiting rod 113 to move out of the limiting hole 114, and then it is rotated on the fixed block 104 to lay it flat. At the same time, the buffer block 105 enters the groove body 108 of the buffer pad 106 to complete the placement. At this time, the base 102 is moved away through the action of the moving wheel 109.

[0030] Among them, the support seat 103 is fixedly connected to the base 102 and is located above the base 102. The support seat 103 has two grooves 107. The multiple fixed blocks 104 are fixedly connected to the support seat 103 and are respectively located inside the corresponding grooves 107. The two ends of the two fan screen display devices 101 are respectively rotatably connected to the corresponding fixed blocks 104 and are located inside the corresponding grooves 107. The two limiting units are symmetrically arranged above the support seat 103. The two buffer blocks 105 are respectively fixedly connected to the corresponding fan screen display devices 101 and are located on one side of the fan screen display device 101. The two buffer pads 106 are fixedly connected to the base 102 and are symmetrically distributed above the base 102. The two buffer pads 106 have a groove body 108, and each of the groove bodies 108 is mutually adapted with the corresponding buffer blocks 105. The fan screen display device 101 performs a holographic 3D display. When use is over, the limit is canceled by the limit unit, and then it is rotated on the fixed block 104 to be laid flat. At the same time, the buffer block 105 enters the groove 108 of the buffer pad 106 to complete the placement. At this time, the base 102 can be moved away. Therefore, the unused fan screen display device 101 can be folded and carried, which can avoid damage and can be quickly moved away to save space.

[0031] Secondly, the plurality of moving wheels 109 are fixedly connected to the base 102, and the plurality of moving wheels 109 are sequentially distributed below the base 102. The moving wheels 109 can move the base 102 without manual handling.

[0032] At the same time, the two ends of the spring 111 are movably connected to the upper part of the support seat 103 and the connecting plate 112, one end of the limiting rod 113 is fixedly connected to the connecting plate 112 and is located below the connecting plate 112, the fan screen display device 101 has a limiting hole 114, the other end of the limiting rod 113 is mutually adapted to the limiting hole 114, the two ends of the telescopic rod 110 are fixedly connected to the upper part of the support seat 103 and the connecting plate 112, and the spring 111 is sleeved on the outside of the telescopic rod 110. The spring 111 rebounds and drives the connecting plate 112 to move downward, and the telescopic rod 110 follows the telescopic movement to ensure stability, so that the limiting rod 113 moves downward into the limiting hole 114 to limit the fan screen display device 101. When the limiting is cancelled, the connecting plate 112 is pulled upward to drive the limiting rod 113 to move out of the limiting hole 114.

[0033] When using the utility model to carry the holographic fan screen, the fan screen display device 101 performs a holographic 3D display. After use, the connecting plate 112 is pulled upward to drive the limiting rod 113 to move out of the limiting hole 114, and then rotated on the fixed block 104 to lay it flat. At the same time, the buffer block 105 enters the groove body 108 of the buffer pad 106 to complete the placement. At this time, the base 102 is moved away through the action of the moving wheel 109. Through the above-mentioned structural setting, the fan screen display device 101 that is not in use can be folded and carried, which can avoid damage and can be quickly moved away to save space.

[0036] The utility model provides a holographic fan screen, which also includes two protection components. The protection components include two protection covers 201 , two magnets 202 and a plurality of limit pads 203 . The base 102 has two slide grooves 204 .

[0037] According to this specific embodiment, after the fan screen display device 101 is laid flat, the protective cover 201 is slid upward. The material of the protective cover 201 is metal, so it can be adsorbed on the magnet 202. At the same time, the limiting pad 203 prevents the protective cover 201 from sliding excessively and detaching from the slide groove 204, thereby protecting both sides of the fan screen display device 101 when laid flat, thereby improving the safety of mobile transportation.

[0038] The two protection components are symmetrically arranged on the base 102. The protection components protect both sides of the fan screen display device 101 when it is laid flat.

[0039] Secondly, the base 102 has two slide grooves 204, and the two protective covers 201 are respectively slidably connected to the corresponding slide grooves 204. The two protective covers 201 are symmetrically distributed on both sides of the fan screen display device 101. The two magnets 202 are fixedly connected to the fan screen display device 101 and are symmetrically distributed on both sides of the fan screen display device 101. The two magnets 202 are respectively fitted with the corresponding protective covers 201. After the fan screen display device 101 is laid flat, the protective cover 201 is slid upwards. The material of the protective cover 201 is metal, so it can be adsorbed on the magnet 202.

[0040] Finally, the plurality of limiting pads 203 are respectively fixedly connected to the corresponding protection covers 201, and the plurality of limiting pads 203 are sequentially distributed below the corresponding protection covers 201. The limiting pads 203 prevent the protection covers 201 from excessively sliding and detaching from the slide slots 204.

[0041] When the utility model is used to protect the fan screen display device 101, after the fan screen display device 101 is laid flat, the protective cover 201 is slid upwards. The material of the protective cover 201 is metal, so it can be adsorbed on the magnet 202. At the same time, the limiting pad 203 prevents the protective cover 201 from excessively sliding and detaching from the slide groove 204, thereby protecting both sides of the fan screen display device 101 when laid flat, thereby improving the safety of mobile transportation.
