Description

Technical Field

[0001] The utility model relates to the technical field of LED display assembly, in particular to a longitudinal installation ground beam for an LED display. Background Technique

[0002] An LED display is a display method that controls semiconductor light-emitting diodes. It integrates microelectronics technology, computer technology, and information processing. It has the advantages of bright colors, a wide dynamic range, high brightness, high clarity, low working voltage, low power consumption, long life, impact resistance, bright colors, and stable and reliable operation.

[0003] When installing an LED display, its installation backplane is fixed on the installation ground beam. However, during actual installation, due to insufficient workpiece accuracy or other reasons, sometimes the screw holes of the rod body (or plate body) of the installation backplane cannot be completely aligned with the screw holes on the installation ground beam (there is a certain small angle), resulting in the inability to accurately install the fixing bolts, bringing great trouble to the entire installation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a longitudinal installation ground beam for an LED display, which has the advantage of being able to adapt to special situations during the actual installation process of the installation backplane of the LED display, making the installation smoother, and solving the problem of misalignment of screw holes in the prior art.

[0005] To achieve the above object, the present utility model provides the following technical solution: A longitudinal installation ground beam for an LED display screen, comprising a longitudinal beam plate and two stud supports threadedly installed on one side wall of the longitudinal beam plate. Two operating knobs are rotatably installed on the side of the longitudinal beam plate where the stud supports are located for manual gripping. Two inner sleeves are fixedly welded in the inner cavity of the longitudinal beam plate. A sliding chamber is formed on the side of each of the two inner sleeves facing away from the operating knob. A threaded rod is coaxially connected to each of the two operating knobs, and a side sliding seat is threadedly installed on each of the two threaded rods. The two side sliding seats are respectively in contact with the inner walls of the two sliding chambers, so that when the two threaded rods rotate, they can drive the two side sliding seats to translate in the sliding chambers. An installation block is movably installed on each of the two side sliding seats. The specific installation method between the side sliding seat and the installation block is as follows: A side plate is integrally welded on the side of the installation block facing the side sliding seat, and an arc-shaped sliding bar extending into the inner cavity of the side sliding seat is welded on the side plate. A plurality of inwardly concave deceleration slots are formed on the inner wall of the arc-shaped sliding bar. The inner cavity of the side sliding seat is formed on the side facing the installation block. A fixing plate is fixedly installed in the inner cavity of the side sliding seat by a technique such as welding in the prior art, and a stabilizing seat is welded on the fixing plate. An inner adjustment chute through which the arc-shaped sliding bar slides is formed on the stabilizing seat, and a plurality of spherical protrusions are fixedly welded in the inner adjustment chute. The spherical protrusions are adapted to the deceleration slots, so that when the arc-shaped sliding bar flips, it can drive the spherical protrusions to slide frictionally against the inner wall of the deceleration slots. When a person exerts force, the spherical protrusions can cross the deceleration slots, changing the angle of the installation block. If no force is exerted, the spherical protrusions are stuck in the deceleration slots, restricting the arc-shaped sliding bar, the side plate thereon, and the installation block.

[0006] As a preferred implementation: One side of the stud support is located outside the longitudinal beam plate, and the other side thereof threadedly penetrates into the longitudinal beam plate and is designed perpendicular to the longitudinal beam plate; so that when a person rotates the two stud supports, the relative relationship between the longitudinal beam plate and the stud supports can be changed to adjust the position of the longitudinal beam plate.

[0007] As a preferred implementation: The two threaded rods are parallel to each other, and the two threaded rods are rotatably installed in the longitudinal beam plate; so that the two threaded rods can rotate stably under the drive of the two operating knobs.

[0008] As a preferred implementation: Threaded grooves are tapped on both of the two installation blocks; and the orientation of the threaded grooves is designed perpendicular to the orientation of the installation blocks, and bolts are installed in the threaded grooves.

[0009] As a preferred implementation: The arc-shaped sliding bar is designed in a C shape and fits with the inner adjustment chute; so that the arc-shaped sliding bar can overcome the frictional resistance and slowly slide in the inner adjustment chute, thereby adjusting the angle of the installation block.

[0010] As a preferred implementation: The plurality of deceleration slots are equally spaced along the inner wall of the arc-shaped sliding bar.

[0011] As a preferred embodiment: A plurality of spherical bumps are evenly distributed along the inner wall of the inner adjustment chute.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: In the present utility model, by rotating the operation handle to drive the threaded rod to operate, the height of the mounting block and the screw groove thereon can be adjusted. By manually holding the mounting block and driving the arc-shaped slide bar to rotate, so that a plurality of deceleration card slots cross over a plurality of spherical bumps, the angle of the mounting block and the screw groove thereon can be finely adjusted, so as to adapt to special situations in the actual installation process of the LED display mounting backplane, making the installation smoother.

[0021] Please refer to Figures 1 to 4 , an embodiment provided by the present utility model: a longitudinal installation ground beam for an LED display screen, including a longitudinal beam plate 1 and two stud supports 2 threadedly installed on one side wall of the longitudinal beam plate 1. One side of the stud support 2 is located outside the longitudinal beam plate 1, and the other side thereof threadedly penetrates into the longitudinal beam plate 1 and is designed perpendicular to the longitudinal beam plate 1, so that when a person rotates the two stud supports 2, the relative relationship between the longitudinal beam plate 1 and the stud support 2 can be changed to adjust the position of the longitudinal beam plate 1;

[0022] On one side of the longitudinal beam plate 1 where the stud support 2 is located, two operating handles 3 are rotatably installed for human hands to hold. Two inner sleeves 4 are fixedly welded in the inner cavity of the longitudinal beam plate 1. On one side of the two inner sleeves 4 facing away from the operating handles 3, sliding chambers 5 are formed. One threaded rod 6 is coaxially connected to each of the two operating handles 3. The two threaded rods 6 are parallel to each other and are rotatably installed in the longitudinal beam plate 1, so that the two threaded rods 6 can operate stably driven by the two operating handles 3. And side sliding seats 7 are respectively threadedly installed on the two threaded rods 6. The two side sliding seats 7 are respectively attached to the inner walls of the two sliding chambers 5, so that when the two threaded rods 6 rotate, they can drive the two side sliding seats 7 to translate in the sliding chambers 5. An installation block 8 is movably installed on the two side sliding seats 7. Screw grooves 9 are tapped on the two installation blocks 8, and the orientation of the screw grooves 9 is perpendicular to the orientation of the installation blocks 8. Bolts are installed in the screw grooves 9;

[0023] The specific installation method between the side sliding seat 7 and the installation block 8 is as follows: On the side of the installation block 8 facing the side sliding seat 7, a side plate 10 is integrally welded, and an arc-shaped sliding strip 11 extending into the inner cavity of the side sliding seat 7 is welded on the side plate 10. A plurality of inwardly recessed deceleration card slots 1101 are formed on the inner wall of the arc-shaped sliding strip 11. The plurality of deceleration card slots 1101 are equally spaced along the inner wall of the arc-shaped sliding strip 11. The inner cavity of the side sliding seat 7 is formed on the side facing the installation block 8. A fixing plate 12 is fixedly installed in the inner cavity of the side sliding seat 7. The installation method is a technology such as welding in the prior art. And a stabilizing seat 13 is welded on the fixing plate 12. An inner adjustment chute 1301 through which the arc-shaped sliding strip 11 slides is formed on the stabilizing seat 13. The arc-shaped sliding strip 11 is designed in a C shape and is attached to the inner adjustment chute 1301, so that the arc-shaped sliding strip 11 can slide slowly in the inner adjustment chute 1301 against the frictional resistance, thereby adjusting the angle of the installation block 8;

[0024] In addition, a plurality of spherical convex blocks 1302 are fixedly welded in the inner adjustment chute 1301. The spherical convex blocks 1302 are adapted to the deceleration card slots 1101, so that when the arc-shaped sliding strip 11 flips, it can drive the spherical convex blocks 1302 to have sliding friction with the inner wall of the deceleration card slots 1101. The plurality of spherical convex blocks 1302 are equally spaced along the inner wall of the inner adjustment chute 1301. When a person exerts force, the spherical convex blocks 1302 can cross the deceleration card slots 1101 to change the angle of the installation block 8. If no force is exerted, the spherical convex blocks 1302 are stuck in the deceleration card slots 1101 to limit the arc-shaped sliding strip 11 and the side plate 10 and the installation block 8 thereon.

[0025] Working principle: During the operation of the present utility model, make the screw holes of the plate body (or rod body) on the mounting bracket of the LED display screen close to the screw slots 9 on the two mounting blocks 8, and then bolts can be installed. After the bolts pass through the screw holes of the plate body (or rod body) and then through the screw slots 9 (and are locked with nuts), the mounting bracket of the LED display screen can be fixed to the longitudinal beam plate 1; by rotating the two stud supports 2, the two stud supports 2 can gradually enter the longitudinal beam plate 1 or gradually extend from the longitudinal beam plate 1, so as to adjust the position of the longitudinal beam plate 1; if special circumstances are encountered during the actual installation process: the plate body (or rod body) of the mounting bracket of the LED display screen is not parallel to the mounting block 8, but there is a certain small included angle, then the mounting block 8 can be manually held and rotated, so that the side plate 10 and the arc-shaped sliding strip 11 thereon slide in the internal adjustment chute 1301, so that the multiple deceleration card slots 1101 cross over the multiple spherical bumps 1302, and finally the multiple spherical bumps 1302 are engaged with several of the deceleration card slots 1101, and the angle of the mounting block 8 is adjusted to make the mounting block 8 parallel to the plate body (or rod body). After that, installing the bolts will be smoother and the position will be more accurate.
