Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a display screen frame structure and a display screen. Background Art

[0002] In order to meet the needs of large-size displays, spliced ​​display screens are usually used for display. Compared with existing projectors, spliced ​​display screens not only have a high overall resolution, but are also not affected by sunlight and light. In the later maintenance, only part of the spliced ​​display screen needs to be disassembled for maintenance, and there is no need to replace the entire screen. Spliced ​​display screens are mostly fixed to the display frame by magnetic suction.

[0003] When replacing a single screen, common methods include the following: 1. Pressing the screen inward to make it concave, and then pulling the sides of the screen outward; 2. Inserting a knife or metal plate into the gap between two adjacent screens to widen the gap between the screens; the above operation methods can easily cause damage to the screen; the third method is to use an electric suction cup to absorb and disassemble the screen. Although it is simple to operate and highly safe, it requires the purchase of equipment separately, which increases the cost, and it needs to be carried with you during maintenance, which is inconvenient.

DETAILED DESCRIPTION

[0019] Example 1

[0020] like Figures 1-4 As shown, a display screen frame structure proposed in this embodiment includes a main frame and multiple driving mechanisms.

[0021] The main frame includes multiple transverse connecting rods 1 and multiple vertical connecting rods 2. The transverse connecting rods 1 and the vertical connecting rods 2 have a hollow structure. The multiple transverse connecting rods 1 are arranged side by side, and the adjacent two transverse connecting rods 1 are connected by multiple vertical connecting rods 2; the transverse connecting rods 1 are provided with multiple first heat dissipation holes 102, and the vertical connecting rods 2 are provided with multiple second heat dissipation holes 202. Through the setting of the first heat dissipation holes 102 and the second heat dissipation holes 202, the heat generated by the LED display screen body 3 can be quickly discharged and will not accumulate on the inner side of the main frame; a rectangular limit frame 7 is provided on the front side of the main frame, and a sealing strip 8 is provided on the inner side wall of the rectangular limit frame 7. The rectangular limit frame 7 is used to limit the multiple LED display screen bodies 3, and the setting of the sealing strip 8 can prevent the LED display screen body 3 from being bumped.

[0022] Multiple pushing mechanisms are respectively installed in equal amounts on multiple transverse connecting rods 1. The pushing mechanisms include a rotating rod 4, a pushing block 5 and a pushing frame 6. A plurality of mounting holes 101 are opened on the transverse connecting rod 1. The rotating rod 4 is rotatably installed in the corresponding mounting holes 101. The rotating rod 4 has a "7"-shaped structure. The pushing block 5 is arranged on the inner side of the transverse connecting rod 1. The pushing frame 6 is connected to the pushing block 5. The pushing frame 6 moves through the inner and outer sides of the transverse connecting rod 1.

[0023] A horizontal coordinate 9 is set on the horizontal side of the rectangular limit frame 7, and a vertical coordinate 10 is set on the longitudinal side of the rectangular limit frame 7; a plurality of coordinate points 11 are set at the end of the horizontal connecting rod 1, and the plurality of coordinate points 11 correspond one-to-one to the plurality of pushing mechanisms. The setting of the horizontal coordinate 9, the vertical coordinate 10 and the plurality of coordinate points 11 facilitates the determination of the pushing mechanism corresponding to the LED display screen body 3.

[0024] Specifically, when disassembling a single LED display screen body 3, first determine the horizontal coordinate 9 position and the vertical coordinate 10 position corresponding to the LED display screen body 3, then find the coordinate point 11 corresponding to the LED display screen body 3 on the side of the main frame, push the push frame 6 adjacent to the coordinate point 11 inward, and the movement of the push frame 6 drives the push block 5 to move, and the push block 5 pushes the rotating rod 4 to rotate, thereby pushing out the corresponding LED display screen body 3, thereby realizing the disassembly of the LED display screen body 3; in summary, this technical solution can facilitate the disassembly of the LED display screen body 3 installed on the main frame, its structure is streamlined, no other auxiliary tools are required, and the screen will not be damaged, and it is relatively safe.

[0025] Example 2

[0026] like Figure 1 and Figure 3 As shown, a display screen proposed in this embodiment includes the display screen frame structure of embodiment 1, and further includes:

[0027] Multiple LED display screen bodies 3 are provided with multiple positioning rods 12 on the back of the multiple LED display screen bodies 3, and a first magnet 13 is provided at the end of the positioning rod 12. A slot 201 is provided on the vertical connecting rod 2, and multiple slots 201 are provided in a one-to-one correspondence with multiple positioning rods 12. A second magnet that is magnetically attracted to the first magnet 13 is installed on the inner side of the slot 201; when installing the LED display screen body 3, the positioning rod 12 on the rear side of the LED display screen body 3 is aligned with the slot 201 and inserted, which can realize the limiting effect on the LED display screen body 3. When the positioning rod 12 is inserted into the limited position, the first magnet 13 and the second magnet are adsorbed together, which can realize the fixing of the LED display screen body 3.
