Description

Technical Field

[0001] This invention relates to the field of cable routing technology, and more particularly to a cable tray for an outdoor display screen. Background Technology

[0002] Wall-mounted LED displays are display devices installed on walls and are widely used in advertising, information display, stage backdrops, and other fields. Wall-mounted LED displays are mostly composed of multiple LED screens; the larger the wall-mounted LED display, the more LED screens are used. The front of each LED screen has several groups of LED beads arranged horizontally and vertically, with each group containing independently emitting R, G, and B primary color semiconductors.

[0003] The installation of a wall-mounted LED display screen also requires the installation of power and communication cables. Since it's an outdoor installation, these cables need to be protected. Most existing cable trays are not suitable for outdoor use. Summary of the Invention

[0004] To address the aforementioned problems, this invention discloses a cable management channel for an outdoor display screen, comprising several horizontal rods. U-shaped rods are fixedly connected to the horizontal rods, and a cable management groove is provided below each horizontal rod. The upper sides of the cable management groove have grooves. The two ends of the U-shaped rods are bent and fixedly fitted into the grooves. The horizontal rods and U-shaped rods enhance the overall strength of the device and provide a standing support position depending on the application scenario. Furthermore, the way the U-shaped rods and cable management grooves work together avoids the need for connecting holes in the upper part of the cable management groove, ensuring the waterproof capability of the upper part of the cable management groove.

[0005] The cable tray is internally fixedly connected to a cable bracket. The cable bracket includes a fixed rod with a retaining groove at one end. A rotating rod is rotatably connected to one end of the fixed rod. A protrusion at one end of the rotating rod engages with the retaining groove. The other end of the rotating rod is bent vertically upwards. The cable bracket supports the cables placed inside, and the rotating rod facilitates cable mounting and prevents cables from falling off.

[0006] Preferably, a connecting block is fixedly connected to the horizontal member, and a connecting plate is provided above the connecting block. Several bolts are inserted into the connecting plate, and the bolts are threaded into pre-drilled holes in the connecting block. During the installation and fixing of the cable tray, the supporting member is clamped between the connecting block and the connecting plate and connected by bolts.

[0007] Preferably, a sealing plate is fastened to the bottom of the cable management channel. The sealing plate includes a plate body with both sides bent vertically downwards. Several bent segments are evenly spaced on both sides of the plate body, and these bent segments fasten into pre-set fastening holes at the bottom of the cable management channel. The sealing plate seals the lower end face of the cable management channel.

[0008] Preferably, a crossbar is provided at the bottom of the plate, and the end of the crossbar is fixedly connected to the edge of the plate. The crossbar facilitates the downward pulling out of the sealing plate.

[0009] Preferably, the lower part of the cable management channel is provided with a cable outlet to facilitate the cable passing through the cable management channel.

[0010] The beneficial effects of this invention are as follows:

[0011] 1. The cable management channel is fixed by connecting the groove and U-shaped rod set in the upper side wall, avoiding the need for openings in the upper part of the cable management channel, ensuring its waterproof function, and making it suitable for outdoor use.

[0012] 2. The installation of horizontal and U-shaped bars improves the overall structural strength. In addition, the cable tray is located inside the LED display screen on the wall, and the horizontal and U-shaped bars provide a standing position for construction workers during construction.

[0022] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] like Figures 1 to 6 As shown, a cable tray for an outdoor display screen includes several horizontal rods 1. Four horizontal rods 1 are provided, each with a circular cross-sectional profile. U-shaped rods 2 are fixedly connected to the horizontal rods 1. The horizontal rods 1 and U-shaped rods 2 enhance the structural strength of the cable tray and provide a standing position depending on the application scenario. A cable management channel 3 is provided below the horizontal rods 1 for placing cables. Grooves are provided on both sides of the upper part of the cable management channel 3. The two ends of the U-shaped rods 2 are bent and fixedly engaged in the grooves. This method of fixing the cable management channel 3 with the grooves avoids the need for connection holes in the upper part of the cable management channel 3, ensuring its waterproof effect and making it suitable for outdoor use.

[0024] The cable tray 3 is internally fixedly connected to a cable bracket 7, which supports and holds the placed cables. The cable bracket 7 includes a fixing rod 72, which is fixedly connected to the inner wall of the cable tray 3. One end of the fixing rod 72 is provided with a retaining groove, and the other end is provided with a triangular frame to facilitate fixing to the cable tray 3. One end of the fixing rod 72 is rotatably connected to a rotating rod 71. One end of the rotating rod 71 is provided with a protrusion, which engages with the retaining groove. That is, during the rotation of the rotating rod 71, the rotating rod 71 can rotate upward. During the downward rotation, when the rotating rod 71 is in a horizontal state, the protrusion engages with the retaining groove, which restricts the rotating rod 71 from continuing to rotate downward. Therefore, when placing cables into the cable tray 3, push the rotating rod 71 from below upward. During the process, the rotating rod 71 rotates upward. When the cable passes the rotating rod 71, the cable can be released. The other end of the rotating rod 71 is set to bend vertically upward. This bending setting can prevent the cable from slipping off one end of the rotating rod 71.

[0025] A connecting block 8 is fixedly connected to the horizontal member 1. The connecting block 8 is welded and fixed to the horizontal member 1. A connecting plate 4 is set above the connecting block 8. The connecting plate 4 is a plate piece. Several bolts 9 are inserted through the connecting plate 4. The bolts 9 are threaded and matched with the pre-set threaded holes of the connecting block 8. When installing the cable tray, the connecting block 8 is placed under the member, and then the cable tray is fixed by the connecting plate 4 and the bolts 9. Figure 6 This is a schematic diagram of the cable tray installation.

[0026] A sealing plate 6 is fastened to the bottom of the cable management channel 3. The sealing plate 6 includes a plate body 62, which is a single plate. The two sides of the plate body 62 are bent downwards vertically, that is, the ends of the plate body 62 are U-shaped. Several bending segments 63 are equally spaced on both sides of the plate body 62, and the bending segments 63 are bent upwards to a horizontal state. The bending segments 63 are fastened in the pre-set fastening holes at the bottom of the cable management channel 3. Through the setting of the bending segments 63 and the fastening holes, the sealing plate 6 is fixed inside the cable management channel 3.

[0027] A crossbar 61 is provided below the plate 62. The end of the crossbar 61 is fixedly connected to the edge of the plate 62. The sealing plate 6 can be pulled down by the crossbar 62.

[0028] The lower part of the cable management channel 3 is provided with a cable outlet 5. The cable outlet 5 is provided to facilitate the cable to pass out of the cable management channel 3.

[0029] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
