Description

Technical Field

[0001] The utility model relates to the technical field of splicing screens, and specifically, to a splicing screen adaptable to various environments. Background Art

[0002] In recent years, with the development of display screen technology, large-size and extra-large-size display devices have become more and more common, and splicing screens used in various occasions have emerged. A splicing screen is a display device used to splice multiple screens into a larger-size screen. Each splicing display unit can be used alone as a monitor or can be spliced for use.

[0003] When installing a splicing screen to protect the normal operation of system equipment, the rear cover of the splicing screen generally directly contacts the anti-static floor. However, not every place has an anti-static floor. When the splicing screen is installed on a floor without an anti-static floor, the static electricity generated during the operation of the splicing screen is likely to adsorb dust and oil stains, affecting the normal use of the splicing screen.

[0004] Therefore, in the existing technology, the splicing screen usually installs an ion wind rod to achieve the purpose of eliminating static electricity. However, the connecting parts of the ion wind rods installed by most manufacturers do not have a position adjustment function. For splicing screens of different sizes and specifications, the optimal use positions of their ion wind rods are different, and precise position adjustment is required after installation. Conventional connecting parts cannot adjust the position of the installed ion wind rod to achieve the best use effect. Summary of the Utility Model

[0005] The utility model provides a splicing screen adaptable to various environments, which can adjust the relative position of the ion wind rod to achieve the best use effect.

[0006] The technical solution of the utility model is as follows:

[0007] A splicing screen adaptable to various environments includes a splicing panel and a rear cover. The rear cover and the splicing panel are fixedly connected. An ion wind rod is provided on one side of the rear cover. It is characterized in that a first limiting groove is provided on the ion wind rod, a second limiting groove is provided on the rear cover, a movable mounting bracket is provided on the ion wind rod. The movable mounting bracket is of an L-shaped structure. Positioning holes are opened at both ends of the movable mounting bracket. Limiting blocks are provided on both sides of the first limiting groove and both sides of the second limiting groove. Positioning nuts are provided in both the first limiting groove and the second limiting groove. The maximum outer diameter of the positioning nut is smaller than the distance between the first limiting groove and the second limiting groove, and the minimum outer diameter of the positioning nut is larger than the distance between the two limiting blocks. A positioning bolt for threaded connection with the positioning nut is passed through the positioning hole.

[0008] Further, it includes a positioning rod, a fixing plate, and a buckle body. A number of limiting holes are arranged in sequence on one side of the ion wind rod. The positioning rod passes through the limiting holes, and one end of the hole is embedded in the limiting holes. The fixing plate is fixedly connected to the splicing panel. The buckle body is located on the side of the fixing plate away from the splicing panel, and the buckle body is fixedly connected to the fixing plate. A C-shaped buckle is provided on the buckle body, and the positioning rod passes through the C-shaped buckle.

[0009] Further, guiding ends are provided on both sides of the opening of the C-shaped buckle, and the guiding ends are arc-shaped structures.

[0010] Further, reinforcing ribs are provided on the fixing plate. The cross-section of the reinforcing ribs is a triangular structure. One bottom surface of one side of the reinforcing ribs is fixedly connected to the fixing plate, and the other bottom surface of the other side of the reinforcing ribs is fixedly connected to the buckle body.

[0011] Further, mounting holes are provided on the fixing plate, and connecting pieces are provided in the mounting holes. The connecting pieces are fixedly connected to the splicing panel.

[0012] The working principle and beneficial effects of the present utility model are as follows:

[0013] A first limiting groove is opened on one side of the ion wind rod of the present utility model. A second limiting groove is provided on the side of the rear cover facing the ion wind rod.

Detailed implementation manner

[0021] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present invention.

[0022] As Figures 1 to 5 shown, this embodiment proposes a splicing screen that can adapt to various environments. The ion wind rod 3 is provided with a first limiting groove 14, and the rear cover 2 is provided with a second limiting groove 15. The ion wind rod 3 is provided with a mobile mounting bracket 4. The mobile mounting bracket 4 is of an L-shaped structure. The L-shaped mobile mounting bracket has a compact structure and low cost. Both ends of the mobile mounting bracket 4 are provided with positioning holes 9. Positioning bolts 8 are arranged in the positioning holes 9 at both ends of the mobile mounting bracket 4. The positioning bolts 8 pass through the ion wind rod 3 and the rear cover 2 and are respectively connected to the positioning nuts 19 in the first limiting groove 14 and the second limiting groove 15. When it is necessary to adjust the position of the ion wind rod 3, by rotating the positioning bolt 8, its fixed effect with the connected positioning nuts 19 is lost, so as to adjust the relative position of the ion wind rod 3 on the splicing screen, so that the ion wind rod 3 can be in the best working position and improve the use effect of the ion wind rod 3.

[0023] As Figures 1 to 5 shown, several limiting holes 16 arranged in sequence are provided on one side of the ion wind rod 3. When the position of the ion wind rod 3 changes, the positioning rod 6 can be drawn out from the ion wind rod 3. After the position of the ion wind rod 3 is adjusted, one end of the positioning rod 6 is inserted into the corresponding limiting hole 16 to cooperate with the mobile mounting bracket 4 to achieve fixation and adjustment. The fixing plate 5 is fixedly connected to the splicing panel 1. The buckle body 10 is installed on the side of the fixing plate 5 away from the splicing panel 1. The buckle body 10 is fixedly connected to the fixing plate 5. The fixing plate 5 is provided with a mounting hole 17, and a connecting piece 12 is arranged in the mounting hole 17. The fixing plate 5 and the splicing panel 1 are fixed by the connecting piece 12. The buckle body 10 is provided with a C-shaped buckle 11. The positioning rod 6 passes through the C-shaped buckle 11. The surface circumference of the positioning rod 6 is equal to the inner surface circumference of the C-shaped buckle 11, so that the positioning rod 6 will not be affected when passing through the C-shaped buckle 11, and at the same time, the position of the positioning rod 6 can be fixed.

[0024] As Figure 4 shown, the fixing plate 5 is provided with reinforcing ribs 13. The cross-section of the reinforcing ribs 13 is a triangular structure. One bottom surface of the reinforcing ribs 13 is fixedly connected to the fixing plate 5, and the other bottom surface is fixedly connected to the buckle body 10. The reinforcing ribs 13 can increase the strength and rigidity of the fixing plate 5 and the buckle body 10, and at the same time can also compensate for the stress unevenness caused by the wall thickness difference between the fixing plate 5 and the buckle body 10, thereby preventing deformation.

[0025] As Figure 4 shown, a connecting member 12 is provided in the mounting hole. The connecting member 12 is fixedly connected to the splicing panel 1. The connecting member 12 preferably uses a cross screw. The head of the cross screw has high strength and is relatively firm after countersinking. The cross screw is also relatively convenient to disassemble and assemble. Moreover, when disassembling and assembling, the tool for rotating the cross screw is relatively easy to replace.

[0026] As Figure 4 shown, the edge surfaces of the C-shaped buckle 11 facing the opening are all provided with guiding ends 7. The guiding ends 7 are fixedly connected to the C-shaped buckle 11. The guiding ends 7 are arc-shaped structures. When the two guiding ends 7 extend from the end far away from the fixing plate 5 to the end close to the fixing plate 5, they gradually approach each other, which is convenient for the positioning rod 6 to be inserted into the C-shaped buckle 11.

[0027] As Figures 1 to 5 shown, when the ion wind rod 3 is fixedly installed on the splicing screen, rotate the positioning bolts 8 on the rotating and movable mounting bracket 4. The positioning bolts 8 are slowly loosened and tightened from the connection with the positioning nut 19, so that the movable mounting bracket 4 is not connected to the ion wind rod 3. Push the positioning rod 6 so that one end of it is not inside the ion wind rod 3. At this time, the position of the ion wind rod 3 can be moved. When the ion wind rod 3 reaches the optimal position, because the maximum outer diameter of the positioning nut 19 is smaller than the distance between the first limiting groove 14 or the second limiting groove 15, and the minimum outer diameter of the positioning nut 19 is larger than the distance between the two limiting blocks 18, the positioning nut 19 is always located in the two grooves. When rotating, it can be limited by the distance between the first limiting groove 14 or the second limiting groove 15, and no tools such as a wrench are required for fixing (the positioning nut can also move in the first limiting groove 14 or the second limiting groove, but cannot break away from or fall out between the two limiting blocks 18). Rotate the positioning bolt 8 in the reverse direction to fixedly connect it to the positioning nut 19, and then push the positioning rod 6 into the limiting hole 16 so that it enters the ion wind rod 3, and fix the position of the ion wind rod 3 again. In summary, the position of the ion wind rod 3 on the splicing screen can be changed through the movable mounting bracket 4 and the positioning rod 6.

[0028] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
