Description

Technical Field

[0001] The utility model relates to the technical field of displays, in particular to an LED display screen installation structure. Background Art

[0002] LED display is a display technology that uses colored light-emitting diodes as the main display body. It realizes various images and information by controlling the opening and closing and brightness of each pixel. In actual application, there are several ways to install LED display screens, namely wall-mounted installation, column installation, suspended installation and embedded installation. Suspension installation is more common on site.

[0003] After the LED display is suspended and installed, when encountering strong winds, the front of the display is relatively wide. The larger the windward area, the more fluid needs to be pushed in front of the object, thus forming a larger high-pressure area. At the same time, a larger windward area also means that a larger low-pressure area will be generated behind the object. Because the fluid needs to bypass larger obstacles, the force applied to the entire device will also be greater, and the entire device will break or fall.

[0004] In order to solve the above technical problems, we designed a wind-resistant LED display installation structure. Utility Model Content

[0005] In order to overcome the disadvantage of lack of resistance to strong winds, the technical problem is: to provide a wind-resistant LED display installation structure.

[0006] A LED display screen mounting structure includes a clamping ring, which is connected to a truss through a threaded rod. A connecting plate is fixed to the lower end of the clamping ring. A narrow plate frame is rotatably connected to the connecting plate on the side away from the clamping ring. A wide plate frame is fixed to the side of the narrow plate frame away from the clamping ring. A display is fixed to the side of the wide plate frame away from the clamping ring. A second gear is fixed to the side of the connecting plate away from the clamping ring. A motor is symmetrically fixed to the side of the narrow plate frame close to the clamping ring. A first gear is fixed to the output end of the motor. The first gear and the second gear are meshed with each other. A limiting plate is fixed to the side of the narrow plate frame close to the clamping ring.

[0007] Optionally, a plurality of anti-slip strips are provided on the inner side of the clamping ring to prevent the entire device from vibrating and causing movement of the display.

[0008] Optionally, a fan is also included, which is fixed to the side of the wide plate frame close to the connecting plate, and the wide plate frame is fixed to the side of the narrow plate frame away from the connecting plate. The fan is connected to a connecting pipe on the side away from the connecting plate, and the connecting pipe and the fan are interconnected. The connecting pipe is fixed to the side of the wide plate frame away from the connecting plate, and a round-headed pipe is fixed to the side of the connecting pipe away from the connecting plate, and the round-headed pipe and the connecting pipe are interconnected.

[0009] Optionally, in order to facilitate the airflow in the low-pressure area, the surface of the round-headed tube is set to be very smooth, and the shape of the round-headed tube is streamlined, which can reduce the occurrence of gas separation and turbulence.

[0010] Optionally, a round-headed frame is further included, which is connected to the side of the display away from the wide frame. The round-headed frame is located on the side of the wide frame close to the display. Four limit rods are symmetrically fixed to the side of the round-headed frame close to the wide frame. The wide frame slides on the limit rods. A return spring is fixed between the limit rods and the wide frame. A symmetrical arc frame is connected to the side of the wide frame away from the display.

[0011] Optionally, the place where the round head frame contacts the display is made of rubber material, which can protect the display from wear and tear, and the rubber material can also provide a certain buffering effect.

[0012] Beneficial effect: When we fix the entire device through the clamping ring, the monitor is firmly restricted on the wide board frame. When a strong wind blows, the front of the monitor faces the direction of the wind. In order to reduce the windward area of ​​the monitor, the monitor is rotated and turned sideways, and finally the limit plate is pressed against the connecting plate to limit the rotation, and finally the long side is facing the wind. In this way, the windward area can be reduced, and finally the wind resistance can be reduced, thereby achieving the purpose of protecting the entire device.

[0013] In order to ensure the stability of the connection between the clamping ring and the frame, we need to set multiple sets of anti-slip strips on the inner side of the clamping ring. First, to achieve the purpose of reinforcement. Secondly, the protruding anti-slip strips can also replace the role of gaskets to achieve more secure clamping and fixation.

[0014] When the monitor is rotated 90 degrees, when the gas flows through the entire monitor and the entire fixing frame, the gas flow rate in the windward direction and leeward direction of the monitor is different. The leeward area with lower flow rate will form a low-pressure area. In this way, under the action of Bernoulli's principle, the entire device will have a pressure difference between the leeward and windward sides of the monitor, causing the monitor and the entire device to be subjected to greater static pressure. If this continues for a long time, the connecting plate will vibrate under the strong static pressure, and in severe cases it will break or fall off. In order to avoid these situations, we use a round-headed tube set at the lower end of the wide plate frame to extract the air from the low-pressure area and discharge it through the air outlet of the fan. Through these settings, we can speed up the air flow rate in the low-pressure area, and we can also control the speed of the fan to match the air flow rate in the windward side, and finally achieve the same air flow rate in the leeward and windward sides, thereby reducing the occurrence of static pressure and ultimately protecting the safety of the entire device.

[0015] In order to safely absorb air from low-pressure areas, we set the surface of the round-head tube to be smooth. This can reduce the friction between the air and the surface of the round-head tube and reduce the appearance of additional low-pressure areas. Secondly, we set the appearance of the round-head tube to be streamlined to promote the smooth flow of air around objects, reduce turbulence and air separation, and thus reduce the appearance of low-pressure areas on the back.

[0016] When air flows quickly through the monitor and wide board rack, vibration may occur due to various protrusions on the rack. In order to protect the monitor, we use reset springs to slow down or even prevent the vibration of the monitor. In this way, the monitor can safely withstand strong winds and ensure that the monitor can be used for a longer time.

[0017] We have installed a rubber pad at the connection between the round head frame and the monitor, and the soft rubber pad fits the monitor to ensure that the round head frame will not rub and damage the monitor. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0028] Example 1: A LED display screen installation structure, such as Figures 1-4 As shown, it includes a clamping ring 5, which is connected to the truss through a threaded rod, a connecting plate 4 is fixed to the lower end of the clamping ring 5, and a narrow plate frame 3 is rotatably connected to the lower end of the connecting plate 4. The front end of the narrow plate frame 3 is fixed to the wide plate frame 2, and the front side of the wide plate frame 2 is fixed to the display 1, and the left and right sides of the connecting plate 4 are fixed to the second gear 9. The lower rear side of the narrow plate frame 3 is symmetrically fixed to the motor 7, and the output end of the motor 7 is fixed to the first gear 8. The first gear 8 and the second gear 9 are meshed with each other. The middle part of the lower rear side of the narrow plate frame 3 is fixed to a limiting plate 6.

[0029] When using the display 1, the entire device must first be installed on a high shelf. When a strong wind blows, the operator manually starts the motor 7, and the motor 7 drives the first gear 8 to rotate clockwise. Because the second gear 9 and the first gear 8 are engaged with each other, and because the second gear 9 is fixed to the connecting plate 4, and because the connecting plate 4 is fixed, and the narrow plate frame 3 is rotatably connected to the lower end of the connecting plate 4, the motor 7 and the wide plate frame 2 and the display 1 connected to the narrow plate frame 3 begin to rotate 90 degrees clockwise, so that the display 1 is parallel to the direction of the wind. After the rotation is completed, the limit plate 6 connected to the narrow plate frame 3 contacts the connecting plate 4. When the strong wind stops, the motor 7 can be controlled to rotate counterclockwise to rotate the display 1 back to its original position.

[0030] Example 2: Based on Example 1, Figure 3 As shown, multiple groups of anti-slip strips are provided on the inner side of the clamping ring 5 to prevent the entire device from vibrating and causing the display 1 to move.

[0031] In order to ensure that the entire device does not vibrate when strong winds hit, we have set multiple sets of anti-slip strips on the inner side of the clamping ring 5 to ensure the connection strength between the clamping ring 5 and the frame.

[0032] like Figure 5 and Figure 6As shown, it also includes a fan 10, which is fixedly connected to the lower rear part of the wide plate frame 2, and the wide plate frame 2 is fixedly connected to the lower end of the narrow plate frame 3. Connecting pipes 11 are connected to the left and right sides of the fan 10, and the connecting pipes 11 and the fan 10 are interconnected. The connecting pipe 11 is fixedly connected to the lower rear part of the wide plate frame 2, and a round-headed pipe 12 is fixedly connected to the front end of the connecting pipe 11, and the round-headed pipe 12 and the connecting pipe 11 are interconnected.

[0033] When the display 1 rotates 90 degrees clockwise, the fan 10 starts to operate. Since the fan 10 is interconnected with the connecting tube 11 and the round-head tube 12, when the fan 10 starts to operate, the fan 10 will quickly absorb air from the round-head tube 12, and the air will flow from the connecting tube 11 and finally be discharged from the air outlet of the fan 10.

[0034] like Figure 6 As shown, in order to facilitate the airflow in the low-pressure area, the surface of the round-headed tube 12 is set to be very smooth, and the shape of the round-headed tube 12 is streamlined, which can reduce the occurrence of gas separation and turbulence.

[0035] In order to ensure that the round-head tube 12 can absorb air from the low-pressure area on the back, the surface of the round-head tube 12 is set to be relatively smooth, and the shape of the round-head tube 12 also needs to be streamlined.

[0036] like Figure 7 and Figure 8 As shown, it also includes a round head board frame 13, the round head board frame 13 is connected to the rear side of the display 1, the round head board frame 13 is located on the front side of the wide board frame 2, and four limit rods 15 are fixedly connected symmetrically on the upper and lower sides of the round head board. The wide board frame 2 slides on the limit rods 15, and a return spring 16 is fixed between the limit rods 15 and the wide board frame 2. The upper and lower parts of the left and right sides of the wide board frame 2 are each connected to an arc frame 14.

[0037] When the display 1 is rotated 90 degrees to cope with strong winds, the display 1 and the fixed shelf will vibrate under the disturbance of the airflow. We use the limit rod 15 on the round head plate frame 13 and the return spring 16 between the wide plate frame 2 to reduce the vibration of the display 1 through the elasticity of the return spring 16. The arc frame 14 will also follow the forward and backward movement of the limit rod 15 to extend and shorten, so as to protect the display 1.

[0038] like Figure 8 As shown, the portion where the round head frame 13 contacts the display 1 is made of rubber material, which can protect the display 1 from wear and tear, and the rubber material can also provide a certain buffering effect.

[0039] In order to ensure the safety of the display 1, a rubber pad is provided at the connection between the round head frame 13 and the display 1 to ensure that the round head frame 13 can safely fix the display 1 and prevent the display 1 from being damaged.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
