Description

Technical Field

[0001] This utility model relates to the field of advertising screens, specifically an LED high-definition advertising screen. Background Technology

[0002] LED high-definition advertising screens are advertising display devices that utilize LED technology. They boast outstanding core advantages, including high resolution, wide color gamut, high brightness, and wide viewing angle. They feature high pixel density, accurate color reproduction, clear images even in strong light, and are visible to viewers from different angles. These powerful devices support playback of various multimedia formats, can be remotely controlled intelligently, and can schedule programs. Outdoor models have an IP65 or higher protection rating, enabling them to withstand harsh environments. Modular splicing allows for customization of different sizes and irregular shapes.

[0003] Current advertising screens can display relevant advertising information during use, but there is a problem: traditional advertising screens are mostly supported by feet, and they need to be moved when they are moved. This undoubtedly reduces the convenience of moving the advertising screen. In view of this, the inventor urgently needs to design an advertising screen that is easy to move in order to improve the convenience of using the advertising screen. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an LED high-definition advertising screen to solve the technical problem that traditional LED advertising screens are mostly fixed by support legs, and need to be manually carried when moving, which reduces the convenience of use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an LED high-definition advertising screen, including a support frame, a base plate assembled below the support frame, a plurality of support mechanisms installed below the base plate, the support mechanism including a fixing block, a movable ring threadedly connected to the outer side of the fixing block, an installation groove opened on the inner side of the fixing block, and a universal wheel installed on the inner side of the installation groove by mounting plate bolts; Tighten the movable ring and adjust its longitudinal position by using the threaded connection between the movable ring and the fixed block, thereby adjusting the contact between the caster wheel and the bottom surface.

[0006] By adopting the above technical solution, the mounting groove on the inner side of the fixed block, together with the mounting plate, enables the omnidirectional wheel to be securely assembled, ensuring that the omnidirectional wheel is not easy to fall off or shift during movement. The threaded connection between the movable ring and the fixed block allows the user to flexibly adjust its longitudinal position by turning the movable ring, thereby controlling the contact state between the omnidirectional wheel and the ground, completely eliminating the cumbersome operation of traditional handling, and enabling the advertising screen to quickly adapt to the position adjustment needs of different usage scenarios.

[0007] Furthermore, the fixing block is fixedly connected to the base plate, and several support mechanisms are evenly arranged below the base plate.

[0008] By adopting the above technical solutions, a structural guarantee is provided for the stable operation of the advertising screen. The fixed connection method can effectively distribute the weight of the main body of the advertising screen and the support frame, avoid excessive local stress that could cause structural damage, and extend the overall service life of the equipment.

[0009] Furthermore, the outer side of the movable ring is provided with friction teeth arranged in an equal-spaced ring to provide frictional support for the user.

[0010] By adopting the above technical solution, regardless of whether the user's hands are dry, wet, or slightly dirty, the friction teeth can increase the friction between the hand and the movable ring, allowing the user to easily turn the movable ring without having to exert too much force, thereby adjusting the contact state between the caster wheel and the ground, significantly improving the convenience and labor-saving of operation.

[0011] Furthermore, a rubber ring is attached to the lower surface of the movable ring, and the movable ring moves down to make the rubber ring come into contact with the ground, thus completing the stable placement of the advertising screen.

[0012] By adopting the above technical solution, the friction between the movable ring and the ground is greatly increased, effectively preventing the advertising screen from sliding or shifting due to external impact or slight ground vibration during placement. This ensures the stable parking of the advertising screen and guarantees the normal display of advertising content. The flexible contact between the rubber ring and the ground also avoids direct hard friction between the movable ring and the ground, reducing scratch damage to the ground. It is suitable for various ground materials such as ceramic tiles, marble, and wood flooring, expanding the application scenarios of the advertising screen.

[0013] Furthermore, the support mechanism is entirely made of stainless steel.

[0014] By adopting the above technical solutions, the structural strength of the support mechanism is prevented from decreasing due to rust and corrosion, ensuring that the support mechanism maintains good load-bearing capacity and adjustment performance for a long time. It can stably support the overall weight of the main body of the advertising screen, support frame and other components, and avoid problems such as deformation and breakage of the support mechanism during long-term use, thus providing a solid material guarantee for the safe operation of the equipment.

[0015] Furthermore, an advertising screen body is attached to one side of the support frame, and a camera assembly is installed on the top of the support frame.

[0016] By adopting the above technical solution, when it is necessary to change the advertising content or to inspect and maintain the main body of the advertising screen, the user can quickly remove the main body of the advertising screen from the support frame without disassembling the entire support structure, which greatly improves the convenience of operation, saves maintenance time and labor costs, and the hanging method can also reduce structural damage to the main body of the advertising screen.

[0017] Furthermore, a groove is formed on the outer periphery of the base plate, and a partition frame is engaged on the inner side of the groove to shield the inner support mechanism.

[0018] By adopting the above technical solutions, the fixed blocks, movable rings, casters and other components of the support mechanism are not directly exposed, making the appearance of the LED high-definition advertising screen cleaner and more beautiful, improving the overall visual effect of the equipment. The partition frame can also play a role in protecting against dust and debris, preventing dust, debris and small objects from entering the gaps of the support mechanism, reducing the failure rate of the support mechanism and extending its service life.

[0019] In summary, the present invention has the following main advantages: This utility model uses a support mechanism where a universal wheel is mounted on the inner side of the fixed block via an installation plate, and a movable ring is threaded to the outer side. Twisting the movable ring adjusts the contact state between the universal wheel and the ground, solving the pain point of traditional advertising screens requiring handling when moving. This significantly improves the ease of movement, requires no additional tools, and has a low operating threshold. The fixed block is fixedly connected to the base plate, and the support mechanism is evenly distributed, which can distribute the weight of the support frame and the main body of the advertising screen, avoiding excessive local stress and ensuring the structural stability of the equipment during placement and movement, preventing tilting or damage.

[0022] 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.

[0023] In this embodiment:

[0024] A type of high-definition LED advertising screen, such as Figure 1-4As shown, it includes a support frame 1, a base plate 4 is assembled below the support frame 1, and several support mechanisms 5 are installed below the base plate 4. The support mechanism 5 includes a fixing block 501, a movable ring 502 is threadedly connected to the outer side of the fixing block 501, and an installation groove 503 is opened on the inner side of the fixing block 501. A caster wheel 504 is bolted to the inner side of the installation groove 503 through the installation plate 505. Tightening the movable ring 502, through the threaded connection between the movable ring 502 and the fixed block 501, adjusts the longitudinal position of the movable ring 502, thereby adjusting the contact between the caster wheel 504 and the bottom surface. The mounting groove 503 on the inner side of the fixed block 501, together with the mounting plate 505, ensures the stable assembly of the caster wheel 504, ensuring that the caster wheel 504 is not easily dislodged or shifted during movement. The threaded connection between the movable ring 502 and the fixed block 501 allows users to flexibly adjust its longitudinal position by tightening the movable ring 502, thereby controlling the contact state between the caster wheel 504 and the ground. This completely eliminates the cumbersome operation of traditional handling, allowing the advertising screen to quickly adapt to the position adjustment needs of different usage scenarios. At the same time, no additional tools are needed; switching between moving and fixing can be completed manually, making it easy to operate and suitable for all types of people. Furthermore, the bolted connection between the mounting groove 503 and the mounting plate 505 facilitates the later maintenance and replacement of the caster wheel 504, reducing the cost of using and maintaining the equipment.

[0025] See Figure 3 , Figure 4 The fixing block 501 is fixedly connected to the base plate 4, and several support mechanisms 5 are evenly arranged under the base plate 4, providing structural protection for the stable operation of the advertising screen. The fixed connection method can effectively distribute the weight of the main body 2 of the advertising screen and the support frame 1, avoid excessive local stress causing structural damage, and extend the overall service life of the equipment. At the same time, the arrangement of several support mechanisms 5 evenly arranged under the base plate 4 can evenly transfer the weight of the base plate 4 and the support frame 1, the main body 2 of the advertising screen and other components to each support mechanism 5, ensuring balanced force on the equipment and further improving the stability of the advertising screen when placed. Even in uneven ground environments, the risk of tilting can be reduced by the evenly distributed support points.

[0026] See Figure 3 , Figure 4The outer side of the movable ring 502 is provided with friction teeth 506 arranged in an equal ring to provide frictional support for the user. Regardless of whether the user's hands are dry, wet or slightly dirty, the friction teeth 506 can increase the friction between the hand and the movable ring 502, allowing the user to easily turn the movable ring 502 without using excessive force, thus adjusting the contact state between the caster wheel 504 and the ground. This significantly improves the convenience and effortlessness of operation. At the same time, the equidistant ring arrangement of the friction teeth 506 ensures that the user can obtain uniform friction when turning the movable ring 502 at any angle, resulting in a consistent operating feel and avoiding problems such as adjustment jamming or inability to accurately control the longitudinal position of the movable ring 502 due to uneven force.

[0027] See Figure 3 , Figure 4 A rubber ring is attached to the lower surface of the movable ring 502. When the movable ring 502 moves down, the rubber ring comes into contact with the ground, thus stabilizing the placement of the advertising screen. This significantly increases the friction between the movable ring 502 and the ground, effectively preventing the advertising screen from sliding or shifting due to external impacts or slight ground vibrations during placement. This ensures the advertising screen is stably positioned and guarantees the normal display of advertising content. The flexible contact between the rubber ring and the ground also avoids direct hard friction between the movable ring 502 and the ground, reducing scratch damage to the ground. It is suitable for various floor materials such as ceramic tiles, marble, and wood flooring, expanding the application scenarios of the advertising screen. At the same time, the elasticity of the rubber ring also provides a certain cushioning effect. When the advertising screen is placed on uneven ground, the rubber ring can adapt to the ground undulations through its own deformation, making the contact between the support mechanism 5 and the ground tighter, further improving the placement stability of the advertising screen and preventing the equipment from shaking and damaging the internal components of the advertising screen body 2.

[0028] See Figure 3 , Figure 4 The support mechanism 5 is made entirely of stainless steel, which prevents the structural strength of the support mechanism 5 from decreasing due to rust and corrosion. This ensures that the support mechanism 5 maintains good load-bearing capacity and adjustment performance for a long time, and can stably support the overall weight of the main body of the advertising screen 2, support frame 1 and other components. It also prevents the support mechanism 5 from deforming or breaking during long-term use, providing a solid material guarantee for the safe operation of the equipment. At the same time, the surface of the stainless steel material is smooth and does not easily adhere to stains, making daily cleaning and maintenance simple and requiring less time and effort, thus reducing the maintenance cost of the equipment.

[0029] See Figure 1 , Figure 2The main body of the advertising screen 2 is attached to one side of the support frame 1, and a camera component 3 is installed on the top of the support frame 1. When it is necessary to change the advertising content or to inspect and maintain the main body of the advertising screen 2, the user can quickly remove the main body of the advertising screen 2 from the support frame 1 without disassembling the entire support structure, which greatly improves the convenience of operation and saves maintenance time and labor costs. The hanging method can also reduce structural damage to the main body of the advertising screen 2. At the same time, the camera component 3 installed on the top of the support frame 1 adds additional functions to the advertising screen. The camera component 3 can realize functions such as real-time monitoring, which can not only provide data support for the analysis of advertising campaign effects and help users accurately adjust advertising strategies, but also improve the security of the advertising screen during use and prevent the equipment from being stolen or maliciously damaged.

[0030] See Figure 1 The base plate 4 has a groove 6 formed on its outer periphery. A partition frame is engaged on the inner side of the groove 6 to cover the inner support mechanism 5, preventing the fixed block 501, movable ring 502, caster wheel 504 and other components of the support mechanism 5 from being directly exposed. This makes the appearance of the LED high-definition advertising screen cleaner and more beautiful, improving the overall visual effect of the equipment. The partition frame also plays a role in protecting against dust and debris, preventing dust, debris, small objects and other objects from entering the gaps of the support mechanism 5, reducing the failure rate of the support mechanism 5 and extending its service life. At the same time, the partition frame adopts an engaging installation method, which is convenient to install and remove. When it is necessary to adjust, maintain or replace the support mechanism 5, the user can quickly remove the partition frame from the groove 6. The operation is simple and does not affect the normal use of the support mechanism 5. Moreover, the engaging structure is stable and prevents the partition frame from falling off during the movement or use of the advertising screen.

[0031] The implementation principle of this embodiment is as follows: the main body 2 of the advertising screen is hung on one side of the support frame 1 and the camera component 3 is installed on the top. The base plate 4 is fixedly connected to the bottom of the support frame 1. The fixing block 501 of the support mechanism 5 is connected to the base plate 4. The inner side of the support frame 5 is equipped with a universal wheel 504 through the mounting plate 505 to provide a basis for the movement of the advertising screen. The outer side is threadedly connected to a movable ring 502 with friction teeth 506. A rubber ring is attached to the lower surface of the movable ring 502. In use, the movable ring 502 is turned with the friction teeth 506 and its longitudinal position is adjusted by the threaded connection. This can make the universal wheel 504 grounded to facilitate the movement of the advertising screen, or the rubber ring grounded to make the advertising screen stable. The partition frame that engages in the groove 6 can cover the support mechanism 5.
