[0032] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] See also Figures 1 to 9 The present invention provides an installation structure for an ultra-large transparent photoelectric film screen 1, which is used to install the photoelectric film screen 1. The installation structure includes:

[0034] The frame 2 is provided with a connecting mounting groove 201 and a mounting cavity 202;

[0035] An acrylic plate 3 is arranged in the installation groove 201 and is used to cover the installation cavity 202. The acrylic plate 3 is provided with a plurality of pre-positioning posts 4 at intervals. The plurality of pre-positioning posts 4 are provided with a plurality of positioning nuts 5 corresponding to each other. The positioning nuts 5 are formed with positioning surfaces and are used to press the photoelectric film screen 1.

[0036] The limiting assembly includes a plurality of limiting columns 15 and limiting plates 16 which are arranged in a one-to-one correspondence. The limiting columns 15 are arranged at intervals on the circumference of the frame 2, and the limiting plates 16 are movably arranged on the acrylic plate 3. Under the action of external force, the limiting columns 15 are linked to the limiting plates 16 to abut against the circumference of the photoelectric touch screen;

[0037] The sealing component is stacked with the photoelectric film screen 1.

[0038] In this embodiment, a reinforced concrete foundation that meets the requirements and is applicable is designed according to the scale of the extra-large transparent photoelectric film screen 1. During the foundation construction, column foot anchor bolts are pre-buried to fix the main structure of the frame 2 of the photoelectric film screen 1. The frame 2 has a connected installation groove 201 and an installation cavity 202. The acrylic plate 3 is arranged in the installation groove 201. The design of the acrylic plate 3 is based on the principle of minimizing the splicing seams and facilitating transportation. Four standard-sized 10 cm thick acrylic plates 3 are assembled and spliced ​​into an extra-large acrylic plate 3, and the edges are cut and shaped according to the size requirements of the photoelectric screen. Seamless hot-melt splicing is adopted between the acrylic plates 3 and the acrylic plates 3. Three pre-positioning columns 4 are arranged at intervals on the surface of the acrylic plates 3. The photoelectric film screen 1 is attached to the acrylic plate surface, and the photoelectric film display is fixed to the acrylic plate surface by three positioning nuts 5 arranged one by one corresponding to the pre-positioning columns 4. Photoelectric film design: The display adopts a pre-customized extra-long transparent photoelectric film, and the transparent photoelectric film adopts an on-site assembly process. In terms of the arrangement of the transparent photoelectric film, the ultra-large transparent photoelectric film screen 1 is divided into two independent areas on the left and right sides by the mid-vertical line. The transparent photoelectric films in the two areas are symmetrically installed. The transparent photoelectric films on the left and right sides are combined to form an ultra-large transparent photoelectric film screen 1. The entire screen image is uniformly controlled by the control room. The HUB waterproof profile boxes of the photoelectric film ends of the respective areas on the left and right sides are respectively hidden in the installation cavity 202 of the frame 2; further, a plurality of limiting columns 15 are arranged at intervals on the circumference of the frame 2, and a plurality of limiting plates 16 that cooperate with the limiting columns 15 are movably arranged on the acrylic plate 3. After the positioning nut 5 preliminarily positions the photoelectric film screen 1, the limiting columns 15 are extended into the installation cavity 202. The limiting columns 15 will drive the limiting plates 16 to move so that they are close to the edge of the photoelectric film screen 1, thereby further fixing the screen position and preventing it from shifting; the close-fitting components are stacked on the edge of the photoelectric film screen 1 to improve the overall sealing and protection performance of the photoelectric film screen 1. The installation structure provided by this embodiment is stable, reliable, and easy to install and maintain the ultra-large transparent photoelectric film screen 1.

[0039] The acrylic plate 3 is provided with a movable groove 6, and the limit plate 16 is slidably arranged in the movable groove 6; the movable groove 6 is provided with a guide column 7 and a guide spring 8, and the telescopic ends of the guide column 7 and the guide spring 8 are connected to the limit plate 16.

[0040] In this embodiment, a movable groove 6 is provided on the acrylic plate 3, and the limit plate 16 can slide in the movable groove 6, so as to better adapt to the photoelectric film screen 1 of different sizes or shapes. The limit plate 16 is pushed to move in the movable groove 6 by the limit column 15 and abuts against the peripheral surface of the photoelectric film screen 1 for positioning; further, a guide column 7 and a guide spring 8 are also provided inside the movable groove 6. The function of the guide column 7 is to provide a stable moving track for the limit plate 16 to ensure that its movement direction is accurate; and the guide spring 8 is connected to one end of the limit plate 16. The elastic characteristics of the spring can realize the automatic resetting function of the limit plate 16. The guide column 7 has a telescopic structure. When the guide column 7 and the guide spring 8 are in a free state, they are far away from the circumference of the photoelectric film. When the photoelectric film screen 1 is placed on the pre-positioning column 4, the limit plate 16 gives way, and then the limit plate 16 is linked to the circumference of the photoelectric film screen 1 through the limit column 15. The guide column 7 and the guide spring 8 can also buffer the impact of external forces on the screen and protect the screen from damage. When disassembling and assembling, the limit column 15 is withdrawn from the installation cavity 202, and the guide column 7 automatically restores to a free state under the action of the guide spring 8. The positioning nuts 5 are removed from the pre-positioning columns 4 in turn to maintain the photoelectric film screen 1.

[0041] The cross section of the limiting plate 16 is L-shaped.

[0042] In this embodiment, the limiting column 15 pushes the L-shaped limiting plate 16 to abut against the edge of the photoelectric film screen 1, and provides support for the circumference and surface of the photoelectric film screen 1 in both vertical and horizontal directions, which helps to evenly distribute the externally applied pressure to the edge of the screen and avoid deformation or damage of the screen due to excessive local pressure.

[0043] The acrylic plate 3 is provided with a plurality of receiving grooves 9 and a plurality of support rods 10, the plurality of support rods 10 are arranged one by one corresponding to the receiving grooves 9, and the pre-positioning pillars 4 are arranged on the corresponding support rods 10. Further, the acrylic plate 3 is provided with a running groove 11 connected to the receiving groove 9, the running groove 11 is movably provided with a threaded rod 12, and the support rod 10 is sleeved on the threaded rod 12 through a sleeve 13.

[0044] In this embodiment, three receiving grooves 9 and three supporting rods 10 are set on the acrylic plate 3. After the photoelectric film screen 1 is attached to the acrylic plate 3, a running groove 11 connected to the receiving groove 9 is further set on the acrylic, a threaded rod 12 is rotatably set in the running groove, and the three supporting rods 10 are sleeved on the threaded rod 12 through a sleeve 13. The threaded rod 12 is rotated to hide the three supporting rods 10 and the sleeve 13 in the corresponding receiving grooves 9 and running grooves 11 respectively. Here, the length of the threaded rod 12 should be selected to be consistent with the length of the running groove 11, so that the photoelectric film screen 1 is closely fitted to the board surface of the acrylic plate 3 to compensate for the gap between the two. During this period, you can try to continue to screw the positioning nut 5 to improve the fit between the positioning nut 5 and the photoelectric film screen 1.

[0045] A compression spring 14 is provided between the threaded rod 12 and the walking groove 11 .

[0046] In this embodiment, considering that the photoelectric film screen 1 is installed outdoors, in order to cope with the influence of wind on the photoelectric film screen 1, a compression spring 14 is provided between the threaded rod 12 and the running groove 11. Due to the preload provided by the compression spring 14, the external force acting on the photoelectric film screen 1 is evenly distributed on each support rod 10, reducing the risk of local stress concentration, thereby extending the service life of the screen and the mounting structure. Furthermore, the compression spring 14 is compressed in the running groove 11 under the action of external force, and can apply equal and opposite forces in two relative directions. When the photoelectric film screen 1 is under the influence of wind, the compression spring 14 generates anisotropic counteracting forces in two directions, which can prevent the screen from being displaced due to external vibration or impact, thereby improving the stability of the overall structure.

[0047] The packaging component includes a sealing strip 17 , a pressing strip 19 and a packaging plate 22 which are stacked in sequence.

[0048] In this embodiment, the sealing strip 17 is located in the innermost layer and directly contacts the photovoltaic film screen 1, providing sealing to prevent external pollutants such as dust and moisture from entering the interior of the screen, thereby protecting sensitive electronic components. Materials with good elasticity and weather resistance, such as silicone or rubber, are usually selected to ensure that the sealing effect can be maintained after long-term use; the pressing strip 19 is located above the sealing strip 17 and is used to increase the pressure on the screen to ensure that the sealing strip 17 can fit tightly against the edge of the screen, and also helps to fix the position of the screen. The pressing strip 19 has a slight elasticity or preload to better adapt to the slight unevenness of the screen surface and ensure uniform pressure distribution; the packaging board 22: as the outermost protective barrier, it not only provides physical protection, but also plays an aesthetic role. The packaging board 22 can be made of metal, plastic or other solid materials. Through three layers of different materials and structures, an effective barrier system is formed, which not only ensures the cleanliness of the internal environment, but also enhances the mechanical strength of the overall structure. The stacked packaging component design simplifies the assembly process, so that each component can be installed in sequence, reducing the complexity and facilitating maintenance or replacement of internal components.

[0049] The sealing strip 17 has an L-shaped cross section. The sealing strip 17 is provided with a sealing groove 18 , and the pressing strip 19 is accommodated in the sealing groove 18 .

[0050] In this embodiment, the L-shaped cross-section design enables the sealing strip 17 to better fit the edge of the photoelectric film screen 1 and the surface of the frame 2, forming a tighter sealing environment, preventing pollutants such as dust and moisture from entering the interior of the screen, and protecting sensitive electronic components. At the same time, the sealing strip 17 also adjusts its shape under the action of external force to adapt to dimensional tolerance problems that may exist in the manufacturing process, ensuring that good sealing performance can be maintained even in the case of slight unevenness, and more evenly distributing the pressure from the clamping strip 19 to avoid excessive stress at specific points, thereby reducing the risk of damage to the sealing strip 17 or the screen; the presence of the sealing groove 18 ensures that the clamping strip 19 is firmly accommodated therein and will not easily slide or fall off. By adopting the sealing strip 17 with an L-shaped cross-section and the clamping strip 19 in the sealing groove 18, not only efficient sealing and stable fixing functions are achieved, but also good adaptability and durability are achieved.

[0051] The frame 2 is provided with a plurality of fixing bolts 20 on its circumference for extending into the mounting cavity 202 and compressing the sealing strip 17 and the compression strip 19. Further, the packaging plate 22 is provided with a plurality of compression bolts 21 at intervals, and the compression bolts 21 pass through the packaging plate 22 and abut against the compression strip 19.

[0052] In this embodiment, multiple fixing bolts 20 on the circumference of the frame 2 can directly extend into the installation cavity 202, applying inward pressure to the sealing strip 17 and the clamping strip 19, ensuring that the sealing strip 17 is tightly fitted to the edges of the photoelectric film screen 1 and the frame 2. The use of multiple fixing bolts 20 can distribute the pressure more evenly and avoid the problem of excessive local stress, thereby improving the sealing effect and structural stability. The clamping bolts 21 on the packaging plate 22 pass through the packaging plate 22 and abut against the clamping strip 19, forming a second layer of clamping mechanism, which not only increases the pressure of the clamping strip 19, but also ensures its close fit with the sealing strip 17, achieving the effect of multi-point force and multi-directional force, and ensuring uniform pressure distribution and reliable fixation.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
