Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and specifically to a screen protection structure for LED displays. Background Technology

[0002] LED screens are a new type of imaging electronic device made by arranging light-emitting diodes in sequence. LED is short for Light Emitting Diode; its basic structure consists of a piece of electroluminescent semiconductor material placed on a lead frame and then sealed with epoxy resin. Due to its high brightness, wide viewing angle, and long lifespan, it is widely used in products such as outdoor advertising screens.

[0003] Currently, existing LED displays are often quite large, and their protection relies heavily on external mounting frames. As a result, a large area of ​​the screen's front is exposed, making it susceptible to bumps and damage when the display is idle or needs to be transported, thus affecting its safety. Utility Model Content

[0004] The purpose of this utility model is to provide a protective structure for an LED display screen. A protective plate assembly is installed at the top of a fixed frame. This assembly consists of a retractable third protective plate, a second protective plate, and a first protective plate. With the assistance of a push-pull component, the assembly can be controlled to retract or expand. A rotating mechanism allows the protective plate assembly to rotate stably on the mounting frame, enabling rapid adjustment of its protective angle. During use, the protective plate assembly can be positioned vertically on the mounting frame to provide dust and rain protection. When the device is idle or needs to be moved, the protective plate assembly can be positioned parallel to the mounting frame and expanded to cover the entire LED display screen. This effectively protects the LED display screen from collision damage, significantly improving safety performance and addressing the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an LED display screen protection structure, comprising:

[0006] Mounting frame, wherein an LED display screen is provided inside the mounting frame;

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1-5 The LED display screen protection structure shown includes:

[0027] Mounting frame 1, with an LED display screen 2 installed inside the mounting frame 1;

[0028] The mounting frame 1 is provided with support legs 3 at both ends of its bottom side, and each support leg 3 is provided with a caster wheel 4 at both ends of its bottom side. Based on this, the mounting frame 1 can be supported by the support legs 3, and the caster wheel 4 facilitates the movement of the device.

[0029] The protective plate assembly includes a first protective plate 9 rotatably connected to the top side of the mounting frame 1, a second protective plate 11 retractably connected to the bottom end of the first protective plate 9, a third protective plate 13 retractably connected to the bottom end of the second protective plate 11, a support strip 14 fixed to the bottom end of the third protective plate 13, and a push-pull assembly provided between the support strip 14 and the first protective plate 9.

[0030] The first protective plate 9 has a first storage cavity 10 inside. The top end of the second protective plate 11 slides within the first storage cavity 10. The second protective plate 11 has a second storage cavity 12 inside. The top end of the third protective plate 13 slides within the second storage cavity 12. Slider blocks 18 are symmetrically fixed on both sides of the top ends of the third protective plate 13 and the second protective plate 11. Sliding grooves 17 matching the sliders 18 are symmetrically arranged on both sides of the interior of the first storage cavity 10 and the second storage cavity 12. Based on this, under the limiting guidance of the sliders 18 and the sliding grooves 17, the third protective plate 13 can slide up and down in the second storage cavity 12 inside the second protective plate 11, while the second protective plate 11 can slide up and down in the first storage cavity 10 inside the first protective plate 9. Thus, the third protective plate 13 can be stored inside the second protective plate 11, and the second protective plate 11 can be stored inside the first protective plate 9.

[0031] The push-pull assembly includes an electric push rod 16 fixedly connected to the top side of the first protective plate 9, a support base 15 fixed at the middle end of the support bar 14, and the output end of the electric push rod 16 connected to the support base 15.

[0032] The rotating mechanism includes fixed frames 5 symmetrically arranged on both sides of the mounting frame 1. Each of the two fixed frames 5 has a movable block 6 inside. Connecting seats 8 are symmetrically fixed at both ends of the first protective plate 9. The two movable blocks 6 are symmetrically rotatably connected to the two connecting seats 8 through a rotating shaft and a connecting frame 7.

[0033] One of the fixed frames 5 has a threaded rod 19 rotatably connected to it via a bearing. A movable block 6 is threadedly connected to the outside of the threaded rod 19. The top end of the threaded rod 19 extends outside the fixed frame 5 and is equipped with a drive motor 20. Based on this, the drive motor 20 drives the threaded rod 19 to rotate, which in turn drives the movable block 6 to slide within the fixed frame 5. The movable block 6 then pulls the connecting frame 7 to rotate. With the support and limitation of another set of fixed frames 5, movable block 6, and connecting frame 7, the connecting frame 7 can drive the protective plate assembly to rotate stably at the top of the mounting frame 1 via the connecting seat 8.

[0034] Another fixed frame 5 has a guide rod 21 fixed inside relative to the threaded rod 19, and the movable block 6 is slidably sleeved on the outside of the guide rod 21. Based on this, the stability of the movable block 6 when the fixed frame 5 moves can be further enhanced by the guide rod 21.

[0035] Through the above technical solution:

[0036] In use, the threaded rod 19 can be driven to rotate by the drive motor 20. The threaded rod 19 can drive the movable block 6 to slide within the fixed frame 5. Then, the movable block 6 pulls the connecting frame 7 to rotate. With the support and limitation of another set of fixed frames 5, movable blocks 6, and connecting frames 7, the connecting frame 7 can drive the protective plate assembly to rotate stably at the top of the mounting frame 1 through the connecting seat 8. This allows for quick adjustment of the protective angle of the protective plate assembly. During the use of the LED display screen 2, the protective plate assembly can be controlled to be vertical on the mounting frame 1 to provide a certain degree of dust and rain protection. Furthermore, when the device is idle or needs to be transported or moved, the protective plate assembly can be controlled to be parallel to the mounting frame 1, and the electric push rod 16 can be driven to move the support bar 14 through the support base 15. Then the support bar 14 can drive the protective plate assembly to unfold, that is, control the third protective plate 13 to extend from the second protective plate 11, and the second protective plate 11 to extend from the first protective plate 9, thereby covering the entire LED display screen 2, thus achieving protection for the LED display screen 2, effectively preventing it from being damaged by collision, and greatly improving the safety protection performance.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
