[0017] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0018] This utility model's multi-angle adjustable LED display screen achieves coordinated operation of multiple sliding seats, rotating disks, telescopic components, and a second adjustment seat through its unique design. This endows the display screen with three-dimensional adjustment capabilities, including horizontal sliding, horizontal rotation, radial telescopic movement, and tilt angle adjustment. It supports independent or combined multi-screen layouts and is suitable for various display scenarios. More specifically, when horizontal adjustment is required, the sliding seat moves circumferentially on the support base via an annular groove and a gear system driven by a servo motor, changing the vase's horizontal position. The rotating disk, fixed to the sliding seat, changes the vase's orientation by rotation and supports continuous 360-degree horizontal rotation. The telescopic component, connected to the rotating disk, can extend and retract to adjust the distance between the vase and the support base, thereby controlling the display screen's display radius. For tilt angle adjustment, the second adjustment seat drives an L-shaped rotating plate around a vertical axis via a stepper motor, tilting the vase up and down to ensure precise tilt angle adjustment of the display screen. The linkage frame ensures synchronized changes in the tilt angles of the upper and lower vases, guaranteeing neatness when multiple screens are spliced ​​together. In the composite adjustment, the sliding base, rotating disk, and telescopic components work together to form an inclined ring display array, achieving dynamic tracking display. Through the ring base layout and multiple sets of sliding base positioning, the device can form a circumferential array around the support in the circumferential combination. After radial expansion and angular alignment, it can be spliced ​​into a seamless ring screen. In the linear planar combination, a horizontal or vertical planar display screen is formed through the centralized distribution of support mechanisms and directional telescopic components. The display screen can be dynamically expanded or contracted through synchronous adjustment and linkage, thereby supporting the rapid reconstruction of various display forms and significantly improving the display effect and flexibility.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example

[0027] Please see Figure 1-6 This utility model provides a technical solution:

[0028] An adjustable LED display screen includes a bracket 1, on which an adjustable support mechanism is installed. The adjustable support mechanism includes a sliding seat 5, on which a rotating disk 6 is provided, and on which a telescopic component 7 is fixedly installed. A vase 8 is installed at one end of the telescopic component 7 located outside the bracket 1. The vase 8 is provided with equally spaced mounting slots 9, and an LED display screen is magnetically connected inside each mounting slot 9.

[0029] The telescopic component 7 can be either an electric push rod or a hydraulic telescopic rod.

[0030] The LED display screen's support base 1 consists of a central support column 2 and a bottom disc forming a basic support structure, with an integrated adjustable support mechanism. This adjustable support mechanism includes a sliding base 5, a rotating disk 6, and a telescopic component 7: the sliding base 5 can slide horizontally along the annular seat 11 of the support base 1 to adjust its lateral position; the rotating disk 6 is fixed to the sliding base 5, and its rotation changes the horizontal angle of the telescopic component 7; one end of the telescopic component 7 is connected to the rotating disk 6, and the other end extends to the outside of the support and mounts a vase 8 structure. Multiple mounting slots 9 are evenly distributed on the surface of the vase 8, which, through a combination of magnetic attraction and positioning pins, secure the LED display screen, enabling rapid installation and precise positioning.

[0031] This design gives the display screen three-dimensional adjustment capabilities, including horizontal sliding, horizontal rotation, and radial telescopic functions. Meanwhile, the modular mounting slot 9 supports independent or combined layouts of multiple screens to adapt to diverse scenario needs.

[0032] Furthermore, the bracket 1 is provided with a ring seat 11, on which multiple sets of adjustable support mechanisms are detachably mounted; the bracket 1 is equipped with detachable ring seats 11, which are connected to the support column by buckles or bolts. Each ring seat 11 can be configured with multiple sets of adjustable support mechanisms, and multiple ring seats 11 can be stacked vertically along the support column. This structure allows the support mechanisms to form a ring array around the bracket, supporting 360-degree surround display, suitable for scenarios such as exhibition halls; stacking ring seats 11 can vertically expand the display density, constructing a three-dimensional display matrix.

[0033] Furthermore, an annular groove 12 is provided on one side of the annular seat 11. The sliding seat 5 is slidably connected to the inside of the annular groove 12. A continuous toothed groove is provided on one side of the inside of the annular groove 12. A drive assembly that engages with the toothed groove is mounted on the sliding seat 5. The drive assembly includes a drive gear 15 and a servo motor 16. The drive shaft of the servo motor 16 is fixedly connected to the drive gear 15, and the drive gear 15 meshes with the toothed groove inside the annular groove 12.

[0034] An annular groove 12 is formed on the inner side of the annular seat 11, through which the sliding seat 5 moves circumferentially. The inner wall of the groove has continuous toothed grooves that mesh with the drive component integrated on the sliding seat 5. When the servo motor 16 drives the gear 15 to rotate, the meshing of the toothed grooves pushes the sliding seat 5 to move precisely along the groove. The control system can preset paths to achieve synchronous or independent movement of multiple sets of sliding seats 5. By replacing traditional manual adjustment with an electric drive mechanism, high-precision positioning is achieved, supporting the dynamic arrangement of the display screen along the annular trajectory, meeting the needs of rotating advertisements and tracking information display.

[0035] Furthermore, a second adjusting seat is provided between the telescopic component 7 of the adjustable support mechanism and the vase 8. The second adjusting seat includes a cylindrical seat 18, inside which a stepper motor 19 is installed. A rotating plate 20 is rotatably fitted to the outside of the cylindrical seat 18. The rotating plate 20 is L-shaped, and the drive shaft of the stepper motor 19 is fixedly connected to the rotating plate 20. The vase 8 is installed on the outside of the rotating plate 20. Ring seats 11 are respectively provided at the upper and lower ends of the support base 1. A linkage frame is fixedly connected between the telescopic components 7 on the upper and lower ring seats 11. The inner ends of the vase 8 are respectively connected to the rotating plate 20.

[0036] A second adjustment seat is added between the telescopic component 7 and the vase 8. Its cylindrical seat 18 houses a stepper motor 19 that drives an L-shaped rotating plate 20 to rotate around a vertical axis. The vase 8 is fixed to the outside of the rotating plate 20. The telescopic components 7 of the upper and lower annular seats 11 are rigidly connected via a linkage frame, ensuring synchronous movement of the two sets of telescopic components 7 and driving the vase 8 to move and adjust stably. This design allows the display screen to adjust its tilt angle, achieving multi-dimensional posture adjustment in conjunction with changes in telescopic length. The linkage frame ensures consistent movement across multiple screens, avoiding misalignment issues when displaying curved surfaces together.

[0037] Furthermore, a quick-installation assembly is provided between the inner side of the vase 8 and the rotating plate 20. The quick-installation assembly includes an insert 23 and a slot 24 that cooperates with the insert 23. Limiting grooves 25 are provided on both sides of the insert 23, and elastic locking tongues 26 are provided on both sides of the slot 24. When the insert 23 is inserted into the slot 24, the elastic locking tongues 26 enter the limiting grooves 25.

[0038] The vase 8 and the rotating plate 20 are connected by a quick-release assembly. When the insert block 23 on the inner side of the vase 8 is inserted into the slot 24 of the rotating plate 20, the elastic locking tongues 26 on both sides of the slot 24 are compressed and retracted. After aligning with the limiting groove 25 of the insert block 23, they automatically spring up and lock. To disassemble, simply press the locking tongues to separate the screen. This structure allows for single-screen assembly and disassembly to be completed within 5 seconds, significantly improving maintenance efficiency. At the same time, the elastic locking design provides continuous clamping force to prevent the display screen from falling off due to equipment vibration.

[0039] Furthermore, the rotating disk 6 includes a first rotating disk 27 and a second rotating disk 28, which are connected by a damping shaft 29. A limiting assembly is installed between the first rotating disk 27 and the second rotating disk 28. The limiting assembly includes a lifting gear ring 31 and a miniature electric push rod 32. The telescopic end of the miniature electric push rod 32 is fixedly connected to the lifting gear ring 31. The miniature electric push rod 32 is fixedly installed inside the first rotating disk 27. The second rotating disk 28 has a toothed groove on the side near the lifting gear ring 31 that mates with the lifting gear ring 31.

[0040] The rotating disk 6 adopts a split structure. The first rotating disk 27 is fixedly connected to the sliding seat 5, and the second rotating disk 28 is fixedly connected to the telescopic component 7. The first rotating disk 27 and the second rotating disk 28 are connected by a damping shaft 29, which provides controllable resistance during rotation. The limiting component includes a lifting gear ring 31 driven by a miniature electric push rod 32 and a matching tooth groove of the second rotating disk 28. During manual adjustment, the damping shaft 29 maintains a smooth feel; after the electric push rod pushes the gear ring to engage the tooth groove, the rotation angle is rigidly locked. This design balances adjustment flexibility and positioning stability, meeting the dual needs of temporary fine-tuning and long-term fixation.

[0041] The LED display screen includes a light-emitting surface and a circuit board. The circuit board is magnetically fixed inside the mounting groove 9. A positioning pin is provided on the side of the circuit board near the mounting groove 9. A positioning pin is provided inside the mounting groove 9 to match the positioning pin. The movable structure at the bottom of the bracket 1 includes casters 39 and an electric lifting column 40. The electric lifting column 40 is installed inside the bracket 1 to support the lifting of the bracket 1.

[0042] The LED display screen is double-fixed by magnetic attraction and positioning pins within the mounting slot 9, and the power supply and signal interfaces are integrated on the circuit board contact surface. The bottom of the bracket base 1 is equipped with braked casters 39 and an electric lifting column 40: the casters 39 support flexible movement of the equipment; the lifting column has a built-in multi-stage hydraulic cylinder, which can adjust the height of the bracket and provide stable support. This combination achieves a balance between rapid deployment and rigid support, facilitating transportation during movement and ensuring display stability when deployed.

[0043] This multi-angle adjustable LED display screen is an innovative and intelligent LED display screen adjustment system. Through its unique adjustable support mechanism, it achieves precise multi-angle adjustment of the vase and the LED display screen, and supports flexible display options for circular and linear planar combinations. Its specific working principle is as follows:

[0044] During horizontal adjustment, the sliding seat 5, driven by a gear system driven by a servo motor 16, moves circumferentially within the annular groove 12, thereby changing the position of the vase 8 and forming a circular array. The rotating disk 6 allows the vase 8 to rotate in the horizontal plane, achieving continuous 360-degree rotation. Furthermore, the telescopic function of the telescopic component 7 can adjust the distance between the vase 8 and the support base 1, thereby controlling the display radius of the screen.

[0045] When adjusting the tilt angle, the second adjustment seat is driven by the stepper motor 19, causing the L-shaped rotating plate 20 to rotate around the vertical axis, thereby tilting the vase 8 up and down and adjusting the tilt angle of the display screen. The linkage frame ensures that the tilt angles of the upper and lower vases 8 change synchronously, ensuring the neatness of multi-screen splicing.

[0046] In the process of compound adjustment, the device can form an inclined ring display array by moving the sliding seat 5, adjusting the rotating disk 6, and extending and retracting the telescopic component 7. When realizing dynamic tracking display, the continuous movement of the sliding seat 5 and the rotating disk 6 is controlled by the servo motor 16, so that multiple displays synchronously follow the moving target.

[0047] In the implementation of the circular combination, the device forms a circular array around the support through the layout of the annular seat 11 and the positioning of multiple sets of sliding seats 5. By radial expansion and angular alignment, it can be spliced ​​into a seamless circular screen, or even form a three-dimensional surround effect.

[0048] For linear planar combinations, the device forms a horizontal or vertical planar display screen through a centrally distributed support mechanism and directional telescopic components 7. The display screen can be dynamically expanded or contracted through synchronous adjustment and linkage.

[0049] The key technological advantage of this device lies in its integration of four degrees of freedom: horizontal translation, horizontal rotation, radial extension, and pitch adjustment working in tandem. It supports both dynamic preset trajectory motion and static fixation, while also possessing the ability to expand laterally and longitudinally, and can be quickly reconfigured to adapt to different scenarios.

[0050] Furthermore, through its innovative adjustment mechanism and combination method, this device breaks through the limitations of traditional LED screens, achieving flexible adaptation of spatial angles and rapid switching of display forms, providing users with a highly flexible and efficient display solution.

[0051] Although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
