Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example: Reference Figure 1-5 The illustrated example is an easily adjustable cultural design publicity board, comprising a mounting back panel 1 and a publicity frame 2 fixed to the front end of the mounting back panel 1. A transparent glass 3 is fixed to the inner side of the publicity frame 2, away from the mounting back panel 1. A cultural design publicity poster is placed in the publicity frame 2.

[0033] A mounting frame 4 is fixed to the upper end of the publicity frame 2, and the mounting frame 4 extends horizontally toward the front side of the publicity frame 2;

[0034] The upper ends of the front and rear sides of the mounting frame 4 are fixed with retractable boxes 5. The two retractable boxes 5 are provided with a long strip-shaped entrance and exit 501 on one side close to each other. The retractable rollers 502 are rotatably connected to the inside of the two retractable boxes 5.

[0035] The sunshade net 6 is wound on the two retracting rollers 502. The middle part of the sunshade net 6 passes through the inlet and outlet 501 and covers the top of the installation frame 4.

[0036] A driving structure 9 is installed on one side of the promotion frame 2 for driving the two retracting rollers 502 to rotate synchronously in the same direction.

[0037] Based on the above structure, when in use, the user can drive the two retracting rollers 502 to rotate synchronously in the same direction through the driving structure 9, thereby winding and moving the sunshade net 6, so that the sunshade net 6 covers the upper end of the installation frame 4 to block the sunlight or light. On the one hand, it can avoid the direct sunlight or light on the transparent glass 3 to produce a reflective area, which is convenient for people to watch the content displayed on the cultural design propaganda column. On the other hand, it can also effectively reduce the occurrence of light pollution. Compared with the existing cultural design propaganda columns, the actual use effect is better.

[0038] Furthermore, the sunshade net 6 includes a sunshade area and an airspace 603, and the sunshade area or the airspace 603 of the sunshade net 6 can cover the inner plane of the frame of the installation frame 4;

[0039] Through the design of the sunshade area and the airspace 603, the sunshade net 6 can produce both sunshade and non-sunshade effects when moving between the two retractable boxes 5, thereby adapting to different lighting conditions while avoiding direct sunlight or light. For example, when it is a pre-cloudy environment or an indoor environment with no lights on, it is only necessary to move the airspace 603 of the sunshade net 6 to overlap with the empty frame area of ​​the installation frame 4, so that light can be directly irradiated on the transparent glass 3, making it easier for people to watch in a non-strong light source environment and eliminating the negative effects of sunshade.

[0040] Furthermore, the sunshade area of ​​the sunshade net 6 further includes a dense mesh portion 601 and a sparse mesh portion 602, the mesh density of the dense mesh portion 601 is greater than the mesh density of the sparse mesh portion 602, and the mesh aperture of the dense mesh portion 601 is smaller than the mesh aperture of the sparse mesh portion 602;

[0041] The dense mesh portion 601, the sparse mesh portion 602 and the airspace 603 have the same shape and area, and the dense mesh portion 601, the sparse mesh portion 602 and the airspace 603 can all cover the inner plane of the frame of the installation frame 4;

[0042] By setting the dense mesh part 601 and the sparse mesh part 602, it is possible to choose to use the dense mesh part 601 or the sparse mesh part 602 to cover the top of the installation frame 4 according to the different light intensities, so as to adapt to the viewing needs under different light intensities, so that the cultural design propaganda column that is easy to adjust can be flexibly applied to a variety of different lighting environment requirements, and the use effect is better.

[0043] It should be noted that the dense mesh portion 601 and the sparse mesh portion 602 can be set to multiple (only two are shown in the figure) areas with successively varying apertures and mesh densities, so as to adapt to different lighting environments in a more refined manner and be more flexible in use.

[0044] Furthermore, frosted glass 7 is fixed on the inside of the mounting frame 4, and the light transmittance of the frosted glass 7 is 90-95%. The sunshade net 6 covers the top of the frosted glass 7. Through the setting of the frosted glass 7, when the light intensity is not strong, the airspace 603 is used to cover the top of the mounting frame 4. When the light passes through the frosted glass 7, it can avoid causing direct radiation to the transparent glass 3, thereby reducing the possibility of reflection. At the same time, the light intensity can also be guaranteed. The adjustment effect is better when the frosted glass 7 is used in conjunction with the sunshade net 6.

[0045] Furthermore, the upper ends of the left and right sides of the mounting frame 4 are fixed with pressure strips 8, the two pressure strips 8 are arranged opposite to each other, and the sides of the two pressure strips 8 close to each other are provided with guide grooves 801, and the left and right sides of the sunshade net 6 are respectively slidably arranged in the two guide grooves 801;

[0046] By setting the edge pressure strip 8, the left and right sides of the sunshade net 6 slide along the guide groove 801 during the movement, thereby avoiding curling, warping and other conditions on both sides of the sunshade net 6, thereby avoiding the edge of the sunshade net 6 from hard wear and tear on the side wall of the storage box 5 when entering and exiting the entrance and exit 501, and can extend the service life of the sunshade net 6 to a certain extent, thereby reducing the maintenance frequency when using the easy-to-adjust cultural design propaganda column.

[0047] Furthermore, the driving structure 9 includes:

[0048] The driving turntable 901 is rotatably connected to one side of the lower end of the promotion frame 2 via a transmission shaft 904;

[0049] Four transmission wheels 902 are provided, two of which are fixed to the ends of the rotating shafts of the two retractable rollers 502, another transmission wheel 902 is fixedly mounted on a transmission shaft 904 connected to the driving turntable 901, and another transmission wheel 902 is coaxially connected to one of the transmission wheels 902 mounted on the ends of the rotating shafts of the retractable rollers 502 via another transmission shaft 904;

[0050] The transmission belt 903 is provided with two transmission belts 903 , and the two transmission belts 903 are respectively transmitted and sleeved between the four corresponding transmission wheels 902 .

[0051] When it is necessary to adjust the sunshade effect of the sunshade net 6, the user only needs to rotate the driving turntable 901 so that the driving turntable 901 drives one of the transmission wheels 902 to rotate through the transmission shaft 904, and one of the transmission wheels 902 can drive the other three transmission wheels 902 to rotate synchronously in the same direction through two transmission belts 903 and another transmission shaft 904, thereby achieving the effect of driving the two retracting rollers 502 to rotate synchronously in the same direction, driving the sunshade net 6 to move horizontally between the two retracting boxes 5, and changing the positions of the dense mesh part 601, the sparse mesh part 602 and the airspace 603 on the sunshade net 6, thereby achieving the purpose of changing the sunshade effect.

[0052] Working principle of the utility model: in daily use, the sunshade net 6 and the frosted glass 7 are used in combination to block strong light, thereby preventing direct sunlight. On the one hand, it can prevent sunlight or light from directly shining on the transparent glass 3 to produce a reflective area, making it easier for people to view the content displayed on the cultural design propaganda column. On the other hand, it can also effectively reduce the generation of light pollution. Compared with the existing cultural design propaganda column, the actual use effect is better.

[0053] When the lighting environment changes, the user only needs to rotate the driving turntable 901 so that the driving turntable 901 drives one of the driving wheels 902 to rotate through the transmission shaft 904, and one of the driving wheels 902 can drive the other three driving wheels 902 to rotate synchronously in the same direction through two transmission belts 903 and another transmission shaft 904, thereby achieving the effect of driving the two retracting rollers 502 to rotate synchronously in the same direction, driving the sunshade net 6 to move horizontally between the two retracting boxes 5, and changing the positions of the dense mesh part 601, the sparse mesh part 602 and the airspace 603 on the sunshade net 6, so that the dense mesh part 601 or the sparse mesh part 602 or the airspace 603 covers the top of the installation frame 4, so that it can adapt to the viewing needs under different light intensities and achieve the purpose of changing the sunshade effect. The cultural design propaganda column that is easy to adjust is simple to operate, suitable for various lighting environments, and has excellent use effect.

[0054] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
