Description

Technical Field

[0001] This utility model relates to the field of viewing angle adjustment rotating bracket technology, and in particular to viewing angle adjustment rotating bracket for LED displays. Background Technology

[0002] LED displays serve as a medium for information presentation, used in advertising, traffic guidance, and stage performances. The quality of the display depends on the screen's pixel density and color reproduction capabilities, which are closely related to the viewing angle. Angle adjustment rotating brackets, as supporting components for LED displays, are used to adjust the angle and orientation of the display, allowing viewers to have a clear and complete visual experience from different positions. By flexibly changing the orientation of the display, the display needs in different scenarios can be met.

[0003] Existing LED displays use viewing angle adjustment rotating brackets, which achieve multi-angle adjustment of the display screen through a combination of mechanical structures. The angle of the display screen can be adjusted according to the direction of pedestrian flow, thereby improving the efficiency of advertising information dissemination. In stage performance scenarios, the brackets, in conjunction with lighting and stage design, enable dynamic angle changes of the display screen, enhancing the performance effect. This demonstrates the role of viewing angle adjustment rotating brackets in improving the flexibility and functionality of LED displays.

[0004] Existing LED display screens with adjustable viewing angle rotating brackets suffer from instability during operation. The bracket structure achieves rotation through the cooperation of bearings and rotating shafts, and uses bolts or clips to fix the angle of the adjusting arm to prevent the display screen from shifting after adjustment. However, there is a certain clearance between the bearings and rotating shafts. Under frequent rotation, the clearance gradually increases due to wear, causing wobbling during rotation. The existing bracket base uses a simple planar contact method with the mounting surface, lacking an effective anti-slip and fixing structure. When the display screen is large or subjected to external impact, the entire bracket is prone to displacement, affecting the stability and safety of the LED display screen. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rotating bracket for adjusting the viewing angle of an LED display screen, aiming to improve the instability of rotating brackets in the prior art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an LED display screen viewing angle adjustment rotating bracket, comprising a base, a fixing ring fixedly connected to the inner top of the base, a ball groove formed in the middle of the inner side of the fixing ring, multiple balls slidably connected to the inner side of the ball groove, a telescopic base column rotatably connected to the inner side of the fixing ring, a groove formed in the middle of the outer side of the telescopic base column, the inner wall of the groove rotatably connected to the outer side of the multiple balls, a telescopic rod one fixedly connected to the top of the telescopic base column, a telescopic rod two slidably connected to the top of the telescopic rod one, a connecting block fixedly connected to the top of the telescopic rod two, a rotating shaft fixedly connected to the front side of the connecting block, connectors fixedly connected to the left and right ends of the front side of the rotating shaft, a connecting plate fixedly connected to the front side of the connectors, and an adjustment and fixing mechanism provided on the front side of the connecting plate, the adjustment and fixing mechanism being adapted to different display screens.

The inner side of each sliding groove is slidably connected to a limiting block. The outer side of the top support rod is provided with multiple limiting holes. The rear side of each limiting block is rotatably connected to a limiting bolt. Each limiting bolt passes through the limiting block and rotates in the corresponding limiting hole.

[0009] As a further description of the above technical solution:

[0010] The bottom of the base is fixedly connected with multiple rubber pads, and expansion holes are provided at the four corners of the top of the base.

[0011] As a further description of the above technical solution:

[0012] A protective pad is fixedly connected to the top of the groove, and two oil plugs are fixedly connected to the top of the connecting block.

[0020] A protective frame is fixedly connected to the front side of the display, and a stop post is fixedly connected between the left and right ends of the two support rods.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the cooperation of the fixing ring, the ball groove and the ball on the base allows the telescopic base column to rotate flexibly inside the fixing ring. The rotating connecting component composed of the connecting block, the rotating shaft, the connector and the connecting plate adjusts the angle of the display screen, realizing the rotating bracket to rotate freely in the horizontal direction, flexibly lift and lower in the vertical direction, and adjust the tilt at multiple angles, thus improving the convenience and flexibility of using the LED display screen.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of an LED display screen viewing angle adjustment rotating bracket, including a base 1. The base 1 provides support for the bracket, ensuring its stability during use. A fixing ring 3 is fixedly connected to the inner top of the base 1, serving as a connection and support. A ball groove 4 is formed in the middle of the inner side of the fixing ring 3, providing sliding space for the balls 5, allowing the components to rotate more smoothly. Multiple balls 5 are slidably connected to the inner side of the ball groove 4, reducing friction and making the telescopic base column 6 rotate more flexibly. The telescopic base column 6 is rotatably connected to the inner side of the fixing ring 3, enabling vertical extension and retraction for easy adjustment of the display screen height. A groove 7 is formed in the middle of the outer side of the telescopic base column 6, accommodating the balls 5. The rotational connection between the telescopic base column 6 and the fixing ring 3 is more stable. The inner wall of the groove 7 is rotatably connected to the outer side of the multiple balls 5. Through the cooperation of the balls 5 and the groove 7, the smoothness of the rotation of the telescopic base column 6 is enhanced. A telescopic rod is fixedly connected to the top of the telescopic base column 6. 8. Telescopic rod 1 and telescopic rod 2 cooperate to achieve flexible height adjustment. Telescopic rod 2 is slidably connected to the top of telescopic rod 1. Telescopic rod 2 slides on telescopic rod 1 to achieve precise adjustment of the overall height of the bracket. Connecting block 10 is fixedly connected to the top of telescopic rod 2. Connecting block 10 is used to connect telescopic rod 2.9 and rotating shaft 11, which serves as a transition and fixation. Rotating shaft 11 is fixedly connected to the front side of connecting block 10. Rotating shaft 11 enables connector 12, connecting plate 13 and display screen to rotate back and forth, which facilitates adjustment of the display screen's viewing angle. Connector 12 is fixedly connected to the left and right ends of the front side of rotating shaft 11. Connector 12 is used to connect rotating shaft 11 and connecting plate 13 to ensure the stability of the connection. Connecting plate 13 is fixedly connected to the front side of connector 12. Connecting plate 13 provides an installation base for adjustment and fixing mechanism 2. Adjustment and fixing mechanism 2 is provided on the front side of connecting plate 13. Adjustment and fixing mechanism 2 is used to adapt to different display screens and adjust and fix them according to the size and shape of the display screen.

[0033] Specifically, when the LED display screen's viewing angle adjustment rotating bracket is in operation, the base 1 first provides stable support for the entire bracket. The ball bearing 5 in the ball bearing groove 4 on the inner side of the fixing ring 3 engages with the groove 7 on the outer side of the telescopic base column 6. When it is necessary to adjust the horizontal angle of the display screen, the telescopic base column 6 rotates flexibly around the fixing ring 3, using the ball bearing 5 as a medium, reducing frictional resistance and achieving smooth 360-degree rotation. To adjust the height of the display screen, the telescopic rod 1 8 and the telescopic rod 2 9 work together to extend and retract. The telescopic rod 2 9 slides on the telescopic rod 1 8. Through the extension and retraction adjustment of both, the precise change of the overall height of the bracket is achieved. Furthermore, when the vertical height of the display screen needs to be changed, and the front and rear viewing angles of the display screen need to be adjusted, the rotating shaft 11 on the front side of the connecting block 10 comes into play. The connector 12 securely connects the rotating shaft 11 to the connecting plate 13, allowing the display screen on the connecting plate 13 to rotate back and forth around the rotating shaft 11, thus achieving flexible adjustment of the display screen viewing angle. The adjustment and fixing mechanism 2 on the front side of the connecting plate 13 makes corresponding adjustments and fixations according to the size and shape of different display screens, ensuring that the display screen is securely installed on the bracket, meeting the diverse needs for adjusting and fixing the angle and height of the LED display screen in different scenarios.

[0034] Reference Figure 1 , Figure 3 and Figure 4 The adjusting and fixing mechanism 2 includes two support rods 201, which provide support for the entire adjusting and fixing mechanism 2 to ensure structural stability. The rear sides of both support rods 201 are fixedly connected to the front sides of connecting plates 13, which stabilize the support structure. Sliding rods 202 are slidably connected to the outer sides of both support rods 201, sliding along the support rods 201 to adjust the height or angle of the support. The top support rod 201 has grooves 203 on its top left and right sides, providing sliding tracks for limiters 204 to facilitate limit functions. Limiters 204 are slidably connected to the inner sides of both grooves 203. The locating block 204 slides and is fixed within the slide groove 203 to limit the movement of the sliding rod 202. Multiple limiting holes 205 are provided on the outer side of the top support rod 201. The limiting holes 205 cooperate with the limiting bolts 206 to provide multiple fixing points for the locating block 204. The rear sides of the two locating blocks 204 are rotatably connected to the limiting bolts 206. The limiting bolts 206 can be tightened or loosened by rotation to fix or unlock the locating blocks 204. Both limiting bolts 206 pass through the locating blocks 204 and rotate in the corresponding limiting holes 205. Through the cooperation of the limiting bolts 206 and the limiting holes 205, the locating blocks 204 are fixed, stabilizing the position of the sliding rod 202.

[0035] Specifically, first rotate the limiting bolt 206 to separate it from the limiting hole 205, releasing the fixation of the limiting block 204 and the restriction on the sliding rod 202. The sliding rod 202 can then slide freely along the support rod 201. The user can adjust it to a suitable height or angle according to actual needs. After adjustment, slide the limiting block 204 along the slide groove 203 to make the limiting block 204 fit against the sliding rod 202, thus initially limiting the movement of the sliding rod 202. Then, rotate the limiting bolt 206 to pass through the limiting block 204 and screw it into the corresponding limiting hole 205 on the outside of the top support rod 201. Through the cooperation of the limiting bolt 206 and the limiting hole 205, the limiting block 204 is firmly fixed in the designated position, stabilizing the position of the sliding rod 202. The two support rods 201 are fixedly connected to the connecting plate 13, providing stable support for the entire adjustment and fixing mechanism 2, ensuring that the entire adjustment and fixing mechanism 2 remains stable and reliable after adjustment.

[0036] Reference Figure 2 and Figure 4 The bottom of the base 1 is fixedly connected with multiple rubber pads 14. The rubber pads 14 increase the friction between the bracket and the placement surface, effectively preventing the bracket from sliding and enhancing the stability of the bracket. The four corners of the top of the base 1 are provided with expansion holes 15. The expansion holes 15 facilitate the subsequent installation of expansion components and expand the function of the bracket according to actual use needs. The top of the groove 7 is fixedly connected with a protective pad 16. The protective pad 16 can prevent the display screen from directly contacting the groove 7 and causing wear, thus playing a good protective role. The top of the connecting block 10 is fixedly connected with two oil plugs 17. The oil plugs 17 facilitate the injection of lubricating oil into the rotating parts of the bracket, reducing friction between rotating parts and ensuring smooth rotation of the bracket. The front sides of the two sliding rods 202 are fixedly connected with support plates 18. The support plates 18 can provide support for the sliding rods 202 and enhance the structural strength and stability of the sliding rods 202. The front sides of the left support plate 18 and the right support plate 18 are fixedly connected with multiple fixing rods 19. The fixing rods 19 are used to fix auxiliary components and improve the overall practicality and multi-functionality of the bracket.

[0037] Specifically, during use, multiple rubber pads 14 are in close contact with the placement surface, increasing the friction between the bracket and the placement surface, effectively preventing the bracket from sliding and ensuring its stability. When functional expansion is required, expansion components can be installed through expansion holes 15 to meet actual usage needs. When placing the display screen, the display screen is placed in the groove 7, and the protective pad 16 prevents the display screen from directly contacting the groove 7 and causing wear, providing good protection. Lubricating oil can be easily injected into the rotating parts of the bracket through the oil plug 17, reducing friction between rotating parts and ensuring smooth rotation of the bracket. During operation, the support plate 18 connected to the front of the two sliding rods 202 provides support for the sliding rods 202, enhancing the structural strength and stability of the sliding rods 202 and ensuring that the sliding rods 202 remain stable during movement. Multiple fixing rods 19 are used to fix auxiliary components, improving the overall practicality and multi-functionality of the bracket, enabling the bracket to adapt to different working scenarios and usage needs.

[0038] Reference Figure 1 and Figure 4 The two left and right fixed rods 19 are fixedly connected to the front of the fixed plate 20. The connection between the fixed rod 19 and the fixed plate 20 provides a stable support for the display 22 component, ensuring the overall structural stability. The multiple fixed rods 19 are designed with equal spacing, which helps to distribute the force evenly and enhance the load-bearing capacity of the bracket. The two fixed plates 20 have multiple ventilation holes 21 inside, which promote air circulation and effectively reduce the temperature of the display 22 during operation. The same display 22 is fixedly connected to the front of the two fixed plates 20, which can stably install the display 22 on the bracket and facilitate viewing angle adjustment. The front of the display 22 is fixedly connected to a protective frame 23, which can protect the screen of the display 22 from collision damage. The left and right ends of the two support rods 201 are fixedly connected to a stop post 24, which limits the movement range of the sliding rod 202 and serves as a positioning and protection function.

[0039] Specifically, the two left-side fixing rods 19 and the right-side fixing rod 19 are connected to the front fixing plate 20 to form the support structure of the bracket. The multiple equidistant fixing rods 19 can evenly distribute the force and enhance the load-bearing capacity of the bracket. The multiple ventilation holes 21 can promote air circulation during the operation of the monitor 22, effectively remove the heat generated by the monitor 22, reduce the operating temperature, and ensure the stability and service life of the monitor 22. The monitor 22 provides for the user's viewing needs. The protective frame 23 connected to the front of the monitor 22 can form a protective barrier for the screen of the monitor 22 during daily use, effectively preventing damage to the screen due to collisions and squeezing. When the sliding rod 202 moves in the bracket structure, the stop post 24 can limit the range of movement and prevent the sliding rod 202 from moving excessively and leaving the normal working area, ensuring the stability and safety of the overall structure of the monitor 22 bracket.

[0040] Working principle: When the LED display screen is working with the viewing angle adjustment rotating bracket, when it is necessary to adjust the horizontal angle of the display screen, the telescopic base column 6 rotates flexibly around the fixed ring 3 with the ball bearing 5 as the medium, reducing frictional resistance and achieving smooth 360-degree rotation. When adjusting the height of the display screen, the telescopic rod 2 9 slides on the telescopic rod 1 8, realizing precise changes in the overall height of the bracket and changing the vertical height position of the display screen. When it is necessary to adjust the front and rear viewing angle of the display screen, the connector 12 securely connects the rotating shaft 11 to the connecting plate 13, so that the display screen on the connecting plate 13 can rotate back and forth around the rotating shaft 11, realizing flexible adjustment of the display screen viewing angle.

[0041] When adapting to different displays, first rotate the limiting bolt 206 to separate it from the limiting hole 205, releasing the fixation of the limiting block 204 and the restriction on the sliding rod 202. The sliding rod 202 can slide freely along the support rod 201. The user can adjust it to a suitable height or angle according to actual needs. After adjustment, slide the limiting block 204 along the slide groove 203 to make the limiting block 204 fit with the sliding rod 202, initially limiting the movement of the sliding rod 202. Rotate the limiting bolt 206 and screw it into the corresponding limiting hole 205 on the outside of the top support rod 201. Through the cooperation of the limiting bolt 206 and the limiting hole 205, the limiting block 204 is firmly fixed in the designated position, stabilizing the position of the sliding rod 202. The two support rods 201 are connected to the connecting plate 13.
