Description

Technical Field

[0001] This utility model relates to the field of road sign technology, specifically to an electronic road sign screen. Background Technology

[0002] In outdoor traffic guidance and advertising scenarios, electronic road signs, with their "combination of road signs and display screens" design, are characterized by the ability to easily change different advertising content and can flexibly adapt to diverse information display needs. Therefore, they are commonly seen in urban outdoor public areas and around commercial districts.

[0003] During typhoon season, some coastal or rainy cities frequently experience typhoon passage, and may even be affected by multiple typhoons in succession. As typhoons move, they can carry various objects such as rocks, branches, and plastic debris. These high-speed moving objects can easily collide directly with the display panels of road sign electronic screens, causing damage such as cracks and breakage. At the same time, compared with the light box components of traditional illuminated light boxes, the display panels of road sign electronic screens have a more complex structure and higher manufacturing and maintenance costs. The replacement cost of a single damaged display panel is much higher than that of traditional light box components, resulting in higher single maintenance costs for users. Moreover, maintenance also requires time for operation and procurement of parts, affecting the aesthetics and the content of the advertisement. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an electronic road sign screen to solve the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electronic road sign screen, including two pillars, each pillar having a mounting bracket fixed to its outer surface. Each mounting bracket has a slot at its top, and the outer surfaces of the slots are connected to a protective plate via two inserts. Each protective plate has a hanging ring fixed to its top two sides. Each slot has a limit block penetrating its top, and multiple limit bolts penetrate the top two sides of each limit block.

[0006] By adopting the above technical solution, the protective plate is assembled using two pillars as the base support and by cooperating with mounting brackets, slots and inserts to build an assembly frame. This provides a stable mounting carrier for the protective plate and allows for detachable assembly of the protective plate through the connection of the inserts and slots. At the same time, the lifting rings facilitate the handling of the protective plate with hoisting equipment, while the limiting blocks and limiting bolts provide additional limits on the inserts. The overall structure takes into account both the protection needs during the typhoon season and the ease of disassembly and assembly during the non-typhoon season, and avoids the protective plate from obstructing the display screen for a long time and affecting its use.

[0007] Furthermore, the protective plate has an arc-shaped cross-section, and the longitudinal section of the side of the protective plate is "C"-shaped.

[0008] By adopting the above technical solutions, the arc-shaped design of the cross section can guide the wind flow in the typhoon to flow smoothly to both sides of the road sign electronic screen, effectively reducing wind resistance and reducing the impact of strong winds on the protective plate and the display screen; the C-shaped structure of the longitudinal section allows the upper and lower back of the protective plate to accurately abut against the outer frame of the display screen, and the two sides of the back to abut against the support column. This not only avoids the protective plate directly contacting the display panel, reducing the risk of the display panel being cracked after the protective plate deforms, but also evenly distributes the impact force of debris or wind force on the front to the support column and the outer frame of the display screen, further reducing the probability of damage to the display panel.

[0009] Furthermore, both the slot and the insert have an "L" shaped cross-section, and the insert is detached from the slot by sliding.

[0010] By adopting the above technical solution, the L-shaped cross-sectional structure allows the slot to restrict the insertion block from falling downwards in the vertical direction and to restrict the insertion block from shifting in the horizontal direction after it is inserted into the slot, thus achieving the initial positioning of the protective plate. The sliding disassembly and connection design does not require the use of complicated tools. The assembly of the insertion block and the slot can be completed simply by placing the protective plate from top to bottom, and the disassembly can be completed by lifting it from bottom to top. This greatly improves the efficiency of protective assembly before the arrival of a typhoon and the removal of protective measures after the typhoon, and avoids long-term interference with the daily use of the display screen.

[0011] Furthermore, the limiting block is detachably connected to the mounting bracket via limiting bolts, and an "L"-shaped protrusion is provided at the bottom of the limiting block, which is detachably connected to the slot.

[0012] By adopting the above technical solution, the L-shaped protrusion at the bottom of the limiting block can be embedded in the slot, forming an upward blockage on the insert block, which makes up for the insufficiency of the slot in only restricting the downward and horizontal displacement of the insert block, as well as restricting the horizontal displacement of the limiting block; at the same time, the detachability of the bolt connection facilitates the subsequent disassembly of the limiting block without affecting the normal disassembly and assembly process of the protective plate.

[0013] Furthermore, the limiting bolt is a high-strength bolt.

[0014] By adopting the above technical solution, the high-strength bolts have excellent tensile strength and structural stability. Under the impact of strong winds during the typhoon season and the force transmitted from the protective plate to the limiting block, they can stably maintain the connection strength between the limiting block and the mounting bracket, prevent the bolts from loosening or breaking due to excessive force, ensure the continuous effectiveness of the limiting structure, and reduce the risk of the protective plate falling off.

[0015] Furthermore, the protective plate and the insert are made of 6061-T6 aluminum alloy or Q235B carbon steel with anti-corrosion paint coating.

[0016] By adopting the above technical solutions, the 6061-T6 aluminum alloy material combines high structural strength with lightweight characteristics, facilitating hoisting and handling while withstanding impacts from debris and wind. The Q235B carbon steel, coated with anti-corrosion paint, possesses good rigidity and corrosion resistance, is less expensive than aluminum alloy, and can withstand harsh outdoor environments such as rain and humidity, reducing material corrosion and loss. Both material choices ensure the durability of the protective plate and inserts, extend component lifespan, and reduce long-term maintenance costs.

[0017] Furthermore, a display screen and a signpost are respectively installed between the two pillars, with the signpost located above the display screen.

[0018] By adopting the above technical solutions, the display screen can flexibly change the advertising content to meet the needs of outdoor information display; the directional sign is located above the display screen, which will not obstruct the display screen and can clearly provide traffic guidance, so that the electronic road sign screen has the dual functions of traffic guidance and commercial promotion, which is in line with the basic functional positioning of outdoor road signs.

[0019] Furthermore, the mounting bracket, slot, protective plate, insert block, limit block, limit bolt, and lifting ring are all provided in two sets, and the two sets of mounting bracket, slot, protective plate, insert block, limit block, limit bolt, and lifting ring are mirror images of each other.

[0020] By adopting the above technical solution, the two sets of components are mirror-assembled on the front and back of the display screen. The front protective plate can block the impact of debris and wind force brought by the typhoon from the front, while the back protective plate can resist the debris rolled up by the typhoon from the back, forming a double protection for the display screen. It is suitable for scenarios with strong typhoon winds and high risk of debris impact, further improving the protection level of the road sign electronic screen.

[0021] Furthermore, the back of the protective plate is fixed with reinforcing ribs, and the reinforcing ribs are in the shape of a grid.

[0022] By adopting the above technical solution, the grid-shaped reinforcing ribs can significantly improve the overall structural strength and deformation resistance of the protective plate without significantly increasing its weight. When the protective plate is subjected to strong wind impact or debris impact, the reinforcing ribs can disperse the local force, reduce the deformation and damage of the protective plate such as bending and breakage, and ensure that the protective plate continues to play a protective role during the typhoon season, avoiding the loss of protection for the display screen due to damage to the protective plate itself.

[0023] In summary, the present invention has the following main advantages: 1. This utility model features a protective plate with an arched cross-section, preventing its back from directly contacting the display panel. This reduces the risk of the protective plate deforming and cracking the display panel. The two sides of the back of the protective plate abut against the support column, while the C-shaped longitudinal section allows the upper and lower parts of the back of the protective plate to abut against the outer frame of the display screen. This distributes the impact force from debris or wind on the front to the support column and the outer frame of the display screen, further reducing the probability of the display panel being damaged by external impact. On the other hand, the arc-shaped surface effectively reduces wind resistance during typhoons, thus reducing the occurrence of display screen damage during typhoons and lowering subsequent replacement and repair costs. 2. This utility model features a mounting frame, slots, inserts, limiting blocks, and limiting bolts. Both the slots and inserts are L-shaped and detachable via sliding. During installation, simply place the protective plate from top to bottom and insert the insert into the slot; the slot then prevents the insert from falling downwards and horizontally. Subsequently, the limiting blocks and high-strength limiting bolts are assembled on top of the mounting frame, further limiting the upward displacement of the insert and protective plate, creating a multi-directional limiting effect and reducing the risk of the protective plate falling off during typhoons. Furthermore, this assembly structure supports quick assembly and disassembly; the protective plate does not require routine installation and is only assembled before a typhoon, thus avoiding disruption to the daily display of advertising content on the screen. 3. This utility model, through the setting of lifting rings, fixes the lifting rings on both sides of the top of the protective plate. When assembling or disassembling the protective plate, it can be used with lifting equipment, eliminating the need for manual handling of heavy protective plates and significantly reducing the intensity of manual labor. At the same time, during the lifting process, manual tools can be used to assist in positioning, which helps to reduce the risk of the protective plate colliding with the display panel of the display screen during the lifting process, and ensures the integrity of the display screen and the protective plate during the assembly and disassembly operations.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] Example 1: A type of electronic road sign screen, such as Figures 2-5As shown, the device includes two support pillars 1. Each support pillar 1 has a mounting bracket 4 fixed to its outer surface. Each mounting bracket 4 has a slot 5 at its top. A protective plate 6 is connected to the outer surface of each slot 5 via two insert blocks 7. Both the slots 5 and the insert blocks 7 have an "L"-shaped cross-section. The insert blocks 7 are detached from the slots 5 by sliding. The protective plate 6 is slowly placed from top to bottom, allowing the insert blocks 7 to slide into the inner wall of the slot 5. At this point, the structure of the slot 5 provides bidirectional restraint for the insert blocks 7, preventing them from falling downwards and also preventing them from shifting horizontally, thus initially achieving the installation and positioning of the protective plate 6. The protective plate 6 has an arc-shaped cross-section. The longitudinal section of the protective plate 6 is C-shaped. When the protective plate 6 plays a protective role during a typhoon, its arc-shaped cross-section design can achieve multiple protective effects simultaneously. On the one hand, the back of the protective plate 6 does not directly contact the display panel of the display screen 2, which reduces the risk of cracking the display panel even if the protective plate 6 is slightly deformed by the typhoon. On the other hand, the arc-shaped surface can guide the airflow to flow more smoothly to both sides of the road sign electronic screen, effectively reducing wind resistance during typhoon weather. At the same time, the two sides of the back of the protective plate 6 abut against the support column 1, and the C-shaped longitudinal section of the protective plate 6 ensures that the upper and lower sides of its back are respectively in contact with the display screen 2. The outer frame abuts against each other, which can evenly distribute the impact force of debris or wind force on the front to the outer frame of the support column 1 and the display screen 2, further reducing the probability of damage to the display panel due to external impact; the protective plate 6 and the insert block 7 are made of 6061-T6 aluminum alloy or Q235B carbon steel with anti-corrosion paint coating, which has both strength and corrosion resistance; the top two sides of the protective plate 6 are fixed with lifting rings 11, and the construction personnel use the lifting rings 11 on the top two sides of the protective plate 6 with the help of vehicle-mounted lifting equipment to move the protective plate 6; the top of the two slots 5 are both penetrated by limit blocks 9, and the bottom of the limit blocks 9 is provided with an "L"-shaped protrusion, which is disengaged from the slot 5. Disconnect the connection. Multiple limiting bolts 10 penetrate both sides of the top of the two limiting blocks 9. The limiting bolts 10 are high-strength bolts. The limiting blocks 9 are disconnected from the mounting frame 4 through the limiting bolts 10. The construction personnel take the limiting blocks 9 and place them on the top of the mounting frame 4, so that the L-shaped protrusion at the bottom of the limiting blocks 9 is embedded in the slot 5. Then, multiple high-strength limiting bolts with excellent tensile strength and stability are screwed into the preset threaded holes. The clamping force of the bolts fixes the limiting blocks 9 on the mounting frame 4. At this time, the protrusion at the bottom of the limiting blocks 9 can form an upward obstruction for the insert 7, preventing the insert 7 from shifting upward under the action of typhoon wind force and avoiding the protective plate 6 from falling off in the typhoon.

[0029] See Figures 1-3 In the above embodiment, a display screen 2 and a directional sign 3 are respectively installed between the two pillars 1. The directional sign 3 is located above the display screen 2. The electronic screen of the directional sign can flexibly change the advertising and other promotional content based on the display screen 2. The directional sign 3 meets the needs of outdoor traffic guidance.

[0030] Example 2: Based on the above embodiment one, in order to further improve the protection effect, the following settings are now implemented.

[0031] See Figure 2 and Figure 3 In the above embodiment, the mounting bracket 4, slot 5, protective plate 6, insert block 7, limiting block 9, limiting bolt 10 and lifting ring 11 are all provided in two sets. The two sets of mounting bracket 4, slot 5, protective plate 6, insert block 7, limiting block 9, limiting bolt 10 and lifting ring 11 are mirror images of each other. The two sets of structures are assembled on the front and back of the display screen 2 in a mirror state. The set of structures on the front provides core protection for the front of the display screen 2, while the set of structures on the back can block the impact of debris or wind force brought by the typhoon from the back, thus forming double protection for the surface and back of the display screen 2 at the same time.

[0032] Example 3: Based on the above embodiment one, the following settings are now adopted to increase structural strength.

[0033] See Figure 5 In the above embodiment, a reinforcing rib 8 is fixed to the back of the protective plate 6. The reinforcing rib 8 is in the shape of a grid. The overall structural strength of the protective plate 6 is enhanced by the supporting effect of the reinforcing rib 8, which reduces the phenomenon of deformation and breakage of the protective plate 6 under strong wind or heavy object impact.

[0034] The implementation principle of this utility model is as follows: First, the basic assembly of the road sign electronic screen is completed. The support column 1 is fixed to the top of the concrete base by anchor bolts. The road sign electronic screen can flexibly change the advertising and other promotional content by relying on the display screen 2. The directional sign 3 meets the outdoor traffic guidance. During normal use outside the typhoon season, the protective plate 6 is not assembled to avoid obstructing the display screen 2 and to ensure that the display screen 2 can perform its information dissemination function normally. When typhoon season arrives and protective preparations are needed, construction workers use the lifting rings 11 on both sides of the top of the protective plate 6, along with vehicle-mounted lifting equipment, to move the protective plate 6. Then, the inserts 7 on both sides of the protective plate 6 are aligned with the slots 5. Since both the slots 5 and the inserts 7 have L-shaped cross-sections, the protective plate 6 can be slowly placed from top to bottom, allowing the inserts 7 to slide into the slots 5 along their inner walls. At this point, the structure of the slots 5 provides bidirectional restraint for the inserts 7, preventing them from falling downwards and also preventing them from shifting horizontally. The initial installation and positioning of the protective plate 6 is achieved. Next, the construction personnel place the limiting block 9 on the top of the mounting frame 4, so that the L-shaped protrusion at the bottom of the limiting block 9 is embedded in the slot 5. Then, multiple high-strength limiting screws with excellent tensile strength and stability are screwed into the preset threaded holes. The limiting block 9 is fixed on the mounting frame 4 by the clamping force of the bolts. At this time, the protrusion at the bottom of the limiting block 9 can form an upward block against the insert 7, preventing the insert 7 from shifting upward under the action of typhoon wind force and avoiding the protective plate 6 from falling off in the typhoon. When the protective plate 6 performs its protective function during a typhoon, its arc-shaped cross-section design provides multiple protective effects simultaneously. Firstly, the back of the protective plate 6 does not directly contact the display panel of the display screen 2, reducing the risk of cracking the display panel even if the typhoon causes slight deformation. Secondly, the arc-shaped surface guides airflow more smoothly to both sides of the road sign screen, effectively reducing wind resistance during typhoons. Simultaneously, the back of the protective plate 6 abuts against the support column 1 on both sides, and the longitudinal section of the protective plate 6 is C-shaped. The back of the panel is designed to abut against the outer frame of the display screen 2 at the top and bottom, which can evenly distribute the impact force of debris or wind on the front to the support column 1 and the outer frame of the display screen 2, further reducing the probability of the display panel being damaged by external impact. Both the protective plate 6 and the insert block 7 are made of 6061-T6 aluminum alloy or Q235B carbon steel with anti-corrosion paint coating, which has both strength and corrosion resistance. At the same time, the overall structural strength of the protective plate 6 is enhanced by the supporting effect of the reinforcing rib 8, reducing the phenomenon of deformation and breakage of the protective plate 6 under strong wind or heavy object impact. In addition, for scenarios requiring a higher level of protection, two sets of mounting brackets 4, slots 5, protective plates 6, inserts 7, limit blocks 9, limit bolts 10, and lifting rings 11 can be used to assemble the two sets of structures in a mirror image on the front and back of the display screen 2 respectively. The set of structures on the front provides core protection for the front of the display screen 2, while the set of structures on the back can block the impact of debris or wind force brought by the typhoon from the back, thus providing double protection for the surface and back of the display screen 2 at the same time. After the typhoon ends, construction workers can first unscrew the limiting bolt 10 from the limiting block 9 and the mounting bracket 4, remove the limiting block 9 and make its bottom protrude out of the slot 5, and then use the vehicle-mounted lifting equipment with the lifting ring 11 to lift the protective plate 6 upward, so that the insert 7 slides upward along the inner wall of the slot 5 and gets out of the slot 5, restoring the road sign electronic screen to its normal working state and ensuring that the display screen 2 can continue to play advertising content normally.
