Description

Technical Field

[0001] The utility model relates to the technical field of LED display screens, and specifically to a display screen bracket and an LED display screen. Background Art

[0002] LED electronic display screens integrate microelectronics technology, computer technology, and information processing, and have the advantages of bright colors, wide dynamic range, high brightness, long life, stable and reliable operation, etc. LED display screens are widely used in commercial media, cultural performance markets, stadiums, information dissemination, news releases, securities trading, etc., and can meet the needs of different environments. Initially, LEDs were used as indicator light sources for instruments and meters. Later, LEDs of various light colors were widely used in traffic lights and large-area display screens, producing good economic and social benefits. Take the 12-inch red traffic light as an example. In the United States, a long-life, low-efficiency 140-watt incandescent lamp was originally used as the light source, which produces 2000 lumens of white light. After passing through the red filter, the light loss is 90%, leaving only 200 lumens of red light. In the newly designed lamps, many companies use 18 red LED light sources, including circuit losses, with a total power consumption of 14 watts to produce the same light effect.

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1~Figure 4 As shown, this embodiment proposes a display bracket and an LED display, including a display body 1, a connector 2 is fixedly connected to one side of the rear of the display body 1, a power cord 3 is fixedly connected to the outside of the display body 1, and a plug 4 is fixedly connected to the outer end of the power cord 3.

[0027] In this embodiment, a support frame 5 is provided at the bottom of the display screen body 1. The four corners of the bottom of the support frame 5 are rotatably connected with universal wheels 6. The bottom of the display screen body 1 is in contact with the top of the support frame 5, which can facilitate the movement of the support frame 5.

[0028] In this embodiment, both sides of the top of the support frame 5 are fixedly connected with fixed plates 7, the tops of the two fixed plates 7 are fixedly connected with supporting plates 8, and both sides of the tops of the supporting plates 8 are fixedly connected with fixed shells 9, which can facilitate the fixed connection of the fixed plates 7.

[0029] In this embodiment, a mounting plate 10 is fixedly installed on the rear side of the display screen body 1, and two fixing columns 11 are fixedly connected to the rear side of the mounting plate 10. The rear sides of the two fixing columns 11 are fixedly connected to fixing columns 2 12, which can facilitate the fixed connection of the fixing columns 11.

[0030] In this embodiment, the bottoms of the two fixing columns 12 are fixedly connected to the adapter plate 13 , and the rear side of the mounting plate 10 is fixedly connected to the connecting column 14 , which can facilitate the fixing of the adapter plate 13 .

[0031] In this embodiment, the connection column 14 is externally fixedly connected to the limiting plate 15 , a clamping plate is fixedly connected between the two fixed shells 9 , and the bottom of the connection column 14 contacts the inside of the clamping plate, which can facilitate the limiting work of the limiting plate 15 .

[0032] When the display screen body 1 needs to be installed on the top of the supporting frame 5, the staff needs to lift the display screen body 1 to the top of the carrying plate 8. The display screen body 1 will synchronously drive the installation plate 10 to move during the movement. The installation plate 10 will synchronously drive the connecting column 14 and the limiting plate 15 to move during the movement. The installation plate 10 will also synchronously drive the fixing column 11 and the fixing column 2 12 to move during the movement. The fixing column 2 12 will synchronously drive the adapter plate 13 to move during the movement. If the adapter plate 13 is inserted into the fixed shell 9, the connecting column 14 will be parked inside the card board. At this time, the display screen body 1 will be fixed because the adapter plate 13 enters the fixed shell 9 and the connecting column 14 enters the card board, thereby facilitating the installation of the display screen body 1.

[0033] Example 2

[0034] like Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a threaded rod 16 is provided inside the bearing plate 8, and the threaded rod 16 is connected to the bearing plate 8 by threads, which can facilitate the rotation of the threaded rod 16.

[0036] When it is necessary to open the display screen body 1, the staff pushes the support frame 5 to move to a suitable position and then inserts the plug 4 into the wall plug. If it is necessary to disassemble the display screen body 1, the staff first needs to rotate the threaded rod 16 clockwise. The threaded rod 16 will be screwed in during the rotation, that is, the threaded rod 16 moves upward, and the threaded rod 16 will simultaneously drive the top plate 17 to push up during the movement. The top plate 17 will simultaneously drive the connecting column 14 and the mounting plate 10 to move upward during the lifting process. The mounting plate 10 will simultaneously drive the display screen body 1 to move upward during the movement. If the mounting plate 10 drives the fixing column 11 and the fixing column 2 12 to move and the adapter plate 13 leaves the interior of the fixed shell 9, the display screen body 1 can be easily taken out by the staff, thereby facilitating the disassembly, assembly, maintenance and replacement of the display screen body 1. When the above work is completed, the staff will simply rotate the threaded rod 16 counterclockwise to reset it.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
