Description

Technical Field

[0001] This utility model relates to the field of LED display technology, specifically to an LED display screen for outdoor stage event backgrounds. Background Technology

[0002] Outdoor stages, as the name suggests, are stages built outdoors. Modern outdoor stages often use large LED displays as backdrops for diverse or visually appealing backgrounds. Existing LED displays for backdrops typically combine multiple LED panels to form a single display. However, this method has several drawbacks. Setting up such displays requires pre-determining the dimensions and selecting suitable brackets. The LED panels are then placed on the brackets for assembly. Once assembled, the bracket structure is fixed, making screen size adjustment impossible. Changing the screen size requires replacing the brackets, which is cumbersome. Furthermore, LED screens are often bolted, making disassembly and replacement difficult in case of malfunctions. Therefore, we propose an LED display for outdoor stage backdrops. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an LED display screen for outdoor stage event backgrounds. The adjustable mounting plate can be installed according to different installation requirements of the LED display screen, and the electromagnet can solve the problem of laborious disassembly after bolt fixing. It can be adapted to the needs of different outdoor stage event backgrounds and can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an LED display screen for outdoor stage event backgrounds, comprising a fixing shell and an LED board;

[0005] Fixed housing: Shaft holes are evenly opened on the right side. A slide is slidably connected in the slide groove on the right side of the fixed housing. A base frame is fixed to the right end of the slide frame. A bolt is fixed to the top surface of the base frame. The bolt is threaded to the screw hole in the middle of the fixed column. An adjustment unit is provided on the outside of the fixed column. A mounting plate is fixed inside the adjustment unit. Mounting iron blocks are fixed at the four corners of the right side of the LED board. The mounting iron blocks are inserted into the mounting holes on the surface of the mounting plate.

[0006] It also includes a controller, which is located on the top surface of the fixed shell. The input terminal of the LED board is electrically connected to the output terminal of the controller, and the input terminal of the controller is electrically connected to the output terminal of an external power supply.

[0007] The mounting block is inserted into the mounting hole on the surface of the mounting plate for fixation. The slide carriage slides inside the slide groove to adjust the position of the base frame, thereby increasing the stability of the device placement.

[0008] Furthermore, the adjustment unit includes a fixed rod, an adjustment frame, a main screw, a locking plate, a support column, and an adjustment bolt. The end of the fixed rod is slidably connected to the outer side of the fixed column. The adjustment frame is slidably mounted on the outer side of the fixed rod. The support column is fixed to the left side of the adjustment frame. The screw hole in the middle of the support column is threadedly connected to the adjustment bolt. The left end of the adjustment bolt is rotatably connected to the middle of the right side of the mounting plate. The screw hole on the right side of the adjustment frame is threadedly connected to the main screw. The left end of the main screw is rotatably connected to the right side of the locking plate. The fixed rod slides to a suitable height outside the fixed column. Rotating the main screw fixes the adjustment frame in the position of the fixed rod. The adjustment bolt is threadedly connected to the support column to adjust the position of the mounting plate. This facilitates the assembly of LED displays of different specifications to suit the needs of different outdoor stage event backgrounds.

[0009] Furthermore, the adjustment unit also includes a rotating wheel, a secondary screw, a bracket, a fixed base, and a connecting plate. The rotating wheel is fixed to one side of the top surface of the fixed housing, and the bottom end of the rotating wheel is connected to the top end of the secondary screw. The secondary screw is threadedly connected to the screw hole on the surface of the bracket. Fixed bases are fixed on both the front and rear sides of the connecting plate. The fixed base has a slot inside. Rotating the rotating wheel causes the bracket to be inserted into the slot inside the fixed base, thus allowing multiple fixed housings to be connected and used.

[0010] Furthermore, the adjustment unit also includes a support plate, a screw, a pressure frame, and a fixing bolt. There are two support plates, which are respectively fixed to both ends of the right side of the fixing rod. The screw is threadedly connected to the screw hole in the middle of the support plate. The pressure frame is rotatably connected to the end of the screw. The fixing bolt passes through the shaft hole on the right side of the fixing shell and is threadedly connected to the screw hole on the surface of the slide. Rotating the screw causes the pressure frame to press against the outside of the fixing column to fix the fixing rod and prevent it from sliding.

[0011] Furthermore, it also includes an electromagnet and a rubber pad. The electromagnet is fixed to the right side of the mounting plate, and the rubber pad is adhered to the left side of the mounting plate. The input end of the electromagnet is electrically connected to the output end of the controller. The electromagnet and the mounting block are magnetically attracted to each other to quickly install and remove the LED board, so as to solve the problem of time-consuming and laborious traditional bolt installation. The adhered rubber pad can increase the stability of the LED board installation.

[0012] Furthermore, it also includes a stop bar and a placement rack. The placement rack is installed corresponding to the through groove on the left side of the fixed housing. There are two stop bars, which are rotatably connected to the two ends of the left side of the fixed housing. Rotating the stop bars installs the placement rack, which allows the electronic components used in the LED board to be placed, and also facilitates subsequent maintenance.

[0014] 1. Slide the fixing rod to the appropriate height on the outside of the fixing column, rotate the main screw to fix the adjusting frame in the position of the fixing rod, and adjust the position of the mounting plate by connecting the adjusting bolt to the support column thread. This makes it easy to assemble LED displays of different specifications to suit the needs of different outdoor stage event backgrounds.

[0015] 2. By rotating the wheel, the inserter is inserted into the slot inside the mounting base. This allows multiple mounting shells to be connected and used. Rotating the lever installs the placement rack, which allows the electronic components used in the LED board to be placed.

[0016] 3. The LED board can be quickly assembled and disassembled by using an electromagnet and a mounting iron block to achieve magnetic attraction, thus solving the problem of time-consuming and labor-intensive traditional bolt installation. The adhesive rubber pad can increase the stability of the LED board installation. Attached Figure Description
