Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and in particular to a concealed installation structure for LED display cables. Background Technology

[0002] LED displays are digital display devices that use semiconductor light-emitting diodes (LEDs) as pixel units and are controlled by electronic circuits to display dynamic images, videos, or text. Their core structure consists of millions of miniature LED beads arranged in a matrix. Each bead can independently emit red, green, and blue light, and by adjusting the current, it achieves 256 levels of grayscale and 16.7 million color gamuts. Combined with high refresh rate driving technology, it can present smooth, ghosting-free, high-definition images. Its technological advantages are concentrated in: superior environmental adaptability, modular and infinitely scalable design, ultra-long lifespan, and energy efficiency. This technology has deeply penetrated six major fields: commercial retail, traffic control, entertainment, sports events, smart cities, and high-end conferences, becoming a core carrier of modern information visualization and communication.

[0003] In existing technologies, LED displays are used in outdoor applications such as building curtain walls and municipal engineering projects. However, LED displays are exposed to harsh environments such as wind, rain, and sun for extended periods, which severely affects their lifespan. In particular, under current technology, the external power and signal cables of traditional outdoor displays are directly exposed to the external environment, posing numerous problems.

[0004] On the one hand, direct sunlight will raise the temperature of the cable, accelerating its aging process. Prolonged exposure to high temperatures will cause the cable's insulation layer to gradually harden and become brittle, eventually leading to cracks and peeling, exposing the internal wires and making them prone to short circuits and other electrical faults. This not only affects the normal use of the display screen but may also pose safety hazards.

[0005] On the other hand, rainwater erosion can cause the metal parts of the cables to rust and corrode, reducing their conductivity and leading to unstable current transmission, which affects the display screen's display effect. Moreover, under some extreme weather conditions, such as strong winds and blizzards, directly exposed cables may be subjected to external forces such as pulling and squeezing, causing the internal wires of the cables to break or the connections to loosen, further affecting the normal operation of the display screen.

[0006] In addition, directly exposed cables can affect the overall aesthetics of the display screen and damage the visual effect of building curtain walls, municipal engineering projects and other places. Utility Model Content

[0007] The main purpose of this utility model is to provide a hidden installation structure for LED display cables, which can effectively solve the problems in the background art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A concealed installation structure for LED display cables includes an LED display body and a cable body. An installation mechanism is located below the LED display body, comprising a U-shaped shell, a cover plate, a cable management plate, an L-shaped plate, a screw, a movable plate, and a latch. The cover plate is fixedly connected to the U-shaped shell via the cable management plate on its rear wall. Cable management plates are fixedly connected to the opposite walls of the U-shaped shell and the cover plate. A set of symmetrical L-shaped plates are also fixedly connected to the two side walls of the cover plate. The screw is movably connected to the L-shaped plates via a rotating rod at one end. The movable plate is movably connected to the screw via a guide groove on its side wall, and a latch is fixedly connected to the side wall of the movable plate.

[0010] Preferably, a wire harness plate is fixedly installed on the inner front wall of the U-shaped shell and the rear wall of the shell cover, and several wire grooves are respectively opened on the opposite side walls of the symmetrical wire harness plates.

[0011] Preferably, the U-shaped shell has two sets of symmetrical mounting holes on the inner front wall and a set of symmetrical positioning openings on the two side walls. A positioning block corresponding to the positioning opening is fixedly installed on the rear wall of the shell cover, and a locking hole is provided on the side wall of the positioning block. A handle is also fixedly installed on the front wall of the shell cover.

[0012] Preferably, a set of symmetrical L-shaped plates are fixedly installed on the two side walls of the U-shaped shell, and a guide bar is fixedly installed on the front wall of the horizontal part of the L-shaped plate, and a rotation hole is opened on the side wall of the vertical part of the L-shaped plate.

[0013] Preferably, a rotating rod is fixedly installed at one end of the screw, and the rotating rod is movably installed in the rotating hole, while a knob is fixedly installed at the other end of the rotating rod.

[0014] Preferably, the rear wall of the movable plate is provided with a guide groove corresponding to the guide bar, and the side wall of the movable plate is provided with a screw hole and is threadedly connected to the screw rod through the screw hole. The side wall of the movable plate and the rear of the screw hole are also fixedly installed with a latch, and the latch is inserted into the latch hole.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this invention, the installation mechanism, with its U-shaped shell secured to the lower wall of the LED display screen via mounting holes and screws, allows the cables on the LED display screen to be placed one by one into the cable trays within the U-shaped shell. The shell cover is then installed onto the U-shaped shell using a handle, with the positioning block inserted into the positioning port. Rotating the knob drives the screw rod, causing the moving plate to move along the screw rod through the screw hole until the latch inserts into the locking hole, thus securing the shell cover to the U-shaped shell. This, combined with the cable tray, enables the orderly fixing and organization of cables, further preventing insulation layer breakage and peeling due to shaking and friction, extending cable lifespan, reducing the probability of short circuits and other electrical faults caused by cable aging, and improving the performance of the LED display. The display screen boasts enhanced safety and stability, and its ability to completely enclose the cables effectively prevents damage from harsh environments such as direct sunlight and rain erosion. This concealed installation of the cables allows for effective protection against extreme weather conditions like strong winds and blizzards. The cables are secured within the U-shaped housing, reducing external forces that could pull or compress them, preventing internal wire breakage or loosening of connections. This ensures the LED display screen operates normally in extreme weather, improving its reliability and resolving the aesthetic issue of exposed cables in traditional outdoor displays. This results in a cleaner and more attractive overall appearance for LED displays within building facades and municipal engineering projects, enhancing visual appeal. Furthermore, it allows for quick and easy opening and closing for maintenance, improving efficiency. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 - Figure 5 As shown, a concealed installation structure for LED display cables includes an LED display body 1 and a cable body 2. An installation mechanism 3 is provided below the LED display body 1. The installation mechanism 3 includes a U-shaped shell 4, a shell cover plate 5, a cable tie plate 7, an L-shaped plate 13, a screw 16, a movable plate 19, and a latch 22. The shell cover plate 5 is fixedly connected to the U-shaped shell 4 through the cable tie plate 7 on the rear wall. Cable tie plates 7 are fixedly connected to the opposite walls of the U-shaped shell 4 and the shell cover plate 5, respectively. A set of symmetrical L-shaped plates 13 are also fixedly connected to the two side walls of the shell cover plate 5. The screw 16 is movably connected to the L-shaped plate 13 through a rotating rod 17 at one end. The movable plate 19 is movably connected to the screw 16 through a guide groove 20 on the side wall. A latch 22 is also fixedly connected to the side wall of the movable plate 19.

[0025] like Figure 3 and Figure 4 As shown, cable trays 7 are fixedly installed on the front inner wall of the U-shaped shell 4 and the rear inner wall of the shell cover 5, and several cable grooves 8 are respectively opened on the opposite side walls of the symmetrical cable trays 7. Cables are placed through the cable grooves 8. The cable trays 7 are used to position and constrain the cables, which can arrange and fix the cable body 2 in an orderly manner, prevent the cable body 2 from getting tangled, and avoid the insulation layer from being worn due to shaking, thus ensuring the normal operation of the cable body 2 and extending the service life of the cable body 2.

[0026] like Figure 3 and Figure 4As shown, the U-shaped shell 4 has two sets of symmetrical mounting holes 11 on its inner front wall. The mounting holes 11 facilitate the installation of the U-shaped shell 4 into the designated position. The U-shaped shell 4 also has a set of symmetrical positioning openings 12 on its two side walls. The shell cover 5 has a positioning block 9 fixedly installed on its rear wall, which corresponds to the positioning opening 12. The positioning opening 12 and the positioning block 9 cooperate to ensure that the shell cover 5 is accurately installed on the U-shaped shell 4, ensuring the accuracy of the installation. The positioning block 9 has a locking hole 10 on its side wall, which cooperates with the subsequent locking tongue 22 to achieve a firm connection. The shell cover 5 also has a handle 6 fixedly installed on its front wall. The handle 6 makes it easier to install and remove the shell cover 5, improving the convenience of operation.

[0027] like Figure 3 and Figure 5 As shown, a set of symmetrical L-shaped plates 13 are fixedly installed on the two side walls of the U-shaped shell 4, and a guide bar 14 is fixedly installed on the front wall of the horizontal part of the L-shaped plate 13. The guide bar 14 is used to cooperate with the guide groove 20 on the moving plate 19 to guide the movement of the moving plate 19. A rotating hole 15 is opened on the side wall of the vertical part of the L-shaped plate 13. The rotating hole 15 is used to install the rotating rod 17 at one end of the screw 16 so that the screw 16 can rotate.

[0028] like Figure 3 and Figure 5 As shown, a rotating rod 17 is fixedly installed at one end of the screw 16, and the rotating rod 17 is movably installed in the rotating hole 15. A knob 18 is fixedly installed at the other end of the rotating rod 17. Rotating the knob 18 can drive the screw 16 to rotate through the rotating rod 17.

[0029] like Figure 3 and Figure 5 As shown, a guide groove 20 corresponding to the guide bar 14 is provided on the rear wall of the movable plate 19, and a screw hole 21 is provided on the side wall of the movable plate 19 and is threadedly connected to the screw rod 16 through the screw hole 21. A latch 22 is also fixedly installed on the side wall of the movable plate 19 behind the screw hole 21, and the latch 22 is inserted into the latch hole 10. The movable plate 19 moves along the screw rod 16 and the guide bar 14 through the screw hole 21 and the guide groove 20 until the latch 22 is inserted into the latch hole 10, so that the shell cover plate 5 can be installed, and a series of hidden installation and fixing functions of the cable body 2 can be realized.

[0030] The specific operating principle of the mounting mechanism 3 in conjunction with the cable body 2 on the LED display screen body 1 is as follows:

[0031] The U-shaped shell 4 can be pre-installed and fixed to the wall below the LED display body 1 through the mounting holes 11 and screws. After placing the multiple cable bodies 2 of the LED display body 1 one by one into the cable trays 8 on the inner cable tray 7 of the U-shaped shell 4, the shell cover 5 is lifted by the handle 6 and installed on the front end of the U-shaped shell 4. The positioning block 9 installed on the rear wall of the shell cover 5 is then inserted into the positioning holes 12 on the side walls of the U-shaped shell 4. Then, the knob 18 located on the outer wall of the L-shaped plate 13 is rotated in sequence. The knob 18 will drive the rotating rod 17 to rotate on the vertical part of the L-shaped plate 13. The rotating plate 19 rotates within the rotating hole 15 on the wall, and the rotating rod 17 drives the screw 16 to rotate. At this time, the moving plate 19 will move inward along the guide strip 14 installed on the front wall of the L-shaped plate 13 and the screw 16 through the screw hole 21 on the side wall and the guide groove 20 on the rear wall. The knob 18 is continuously rotated until the moving plate 19 moves and the latch 22 is inserted into the latch hole 10 on the side wall of the positioning block 9. In this way, the cover plate 5 and the U-shaped shell 4 can be installed and fixed together, and the cable body 2 will be clamped and fixed in the wire groove 8 opened on the opposite wall of the symmetrical cable tray 7, thereby passing through the U-shaped plate 13. The U-shaped shell 4 and the cover plate 5 can completely enclose the cable body 2, enabling concealed installation of the cable body 2. This effectively avoids damage to the cable from harsh environments such as direct sunlight and rain erosion. It also allows for the orderly fixation and organization of the cable body 2, further preventing the insulation layer from cracking or peeling due to shaking or friction, thus extending the service life of the cable body 2 and reducing the probability of electrical faults such as short circuits caused by aging of the cable body 2. This improves the safety and stability of the LED display body 1. When the cable body 2 malfunctions or is damaged and requires maintenance, the knob 18 is rotated in the opposite direction to remove the latch 22 from the latch hole 10. The cover plate 5 can then be removed from the U-shaped shell 4 via the handle 6, allowing for quick location and maintenance of the damaged cable body 2 within the cable tray 7 of the U-shaped shell 4. This ensures that the U-shaped shell 4 can be opened and closed quickly and conveniently, improving maintenance efficiency.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components can be replaced with equivalents or some technical features can be replaced with equivalents. All such improvements within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
