Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, specifically to a sports stadium lighting device with adjustable illumination angle. Background Technology

[0002] Sports venues are professional venues for sports training, competitions, and physical exercise. They are a general term for various sports venues specially built to meet the needs of sports training, competitions, and mass sports consumption. Sports venues are usually located indoors, and lighting is required when exercising indoors.

[0003] However, to prevent dust from entering the lamp body, a patent document with publication number CN212408399U describes a method where both the fixing parts of the sealing ring and the light-transmitting cover are located within the mounting groove. This improves the reliability of the installation of the light-transmitting cover and the sealing ring, preventing the sealing ring from falling out of the mounting groove. The combined effect of the light-transmitting cover and the sealing ring can stably and reliably isolate external dust from the internal LED beads, resulting in excellent dustproof performance.

[0004] Theoretically, the implementation of the aforementioned technical structure is beneficial for dust prevention of LED beads. However, according to the description in the aforementioned technical content, the LED beads are mounted on a mounting platform, and the mounting platform is connected to the mounting bracket by bolts. Since the bolt connection fixes the mounting platform to the mounting base, when it is necessary to adjust the usage angle of the LED beads, the movement of the mounting platform will be restricted by the bolts. This makes it difficult for the mounting platform to move on the mounting bracket after installation, making it inconvenient for the LED beads to be adjusted to different angles, thereby reducing the flexibility of the LED beads in actual use.

By changing the connection method between the through hole 15 and the spring buckle 2, the lamp body 1 can be disassembled or installed.

[0027] Please see Figure 2 , Figure 4 and Figure 5 A fixing block 16 for installing spring clip 2 is fixedly installed on the lower end face of the platform 3, and the outer wall of the fixing block 16 is movably connected with the inner wall of the locking block 13. The fixing block 16 is configured to provide a platform and space for the installation and movement of spring clip 2. Grooves 17 are respectively opened on the front and rear sides of the fixing block 16, and the inner wall of the groove 17 is movably connected with the outer wall of the protrusion 14.

[0028] A disc 18 is fixedly installed at the lower end of the telescopic rod 4. The disc 18 is used to connect the telescopic rod 4 and the second movable rod 19.

The lower end of the second movable rod 19 is connected to the second bracket 20, and the lower end of the second bracket 20 is fixedly connected to the upper surface of the platform 3.

[0029] Please see Figure 8 , Figure 7 and Figure 3 The lifting assembly 6 includes a ball nut 601 and a ball screw 602. The inner wall of the ball nut 601 is threadedly connected to the outer wall of the ball screw 602. The threaded connection allows the circumferential rotation of the ball screw 602 to provide power for the vertical movement of the ball nut 601. The outer end of the ball nut 601 is fixedly connected to the inner wall of the telescopic rod 4. The upper end of the ball screw 602 is fixedly mounted with a drive motor 21 located inside the mounting base 10. A second reducer is provided on the output shaft of the drive motor 21. The second reducer is used to adjust the speed of the output shaft of the drive motor 21. The lower end of the drive motor 21 is fixedly connected to the bottom surface of the inner wall of the mounting base 10.

[0030] Support rods 22 are evenly distributed on the upper surface of the mounting base 10. The support rods 22 are used to connect the mounting base 10 and the mounting frame 23. The mounting base 10 is rotatably connected to the mounting frame 23 through the support rods 22. The lower surface of the mounting frame 23 is fixedly connected to the upper end of the rotary motor 12. Mounting plates 24 are evenly distributed on the outer wall of the mounting frame 23. Expansion screws 25 are movably installed on the inner wall of the mounting plates 24.

[0031] Working principle: In use, first, turn on the power of the rotary motor 12. After the rotary motor 12 is turned on, it drives the mounting base 10 to rotate under the mounting frame 23 through the connection of the rotating shaft 11. Due to the connection between the support rod 22, the mounting base 10, and the mounting frame 23, the rotation of the mounting base 10 drives the lamp body 1 to rotate horizontally through the connection of the first movable rod 9, the first bracket 8, the platform 3, and the spring buckle 2, thus realizing the adjustment of the horizontal lighting position of the lamp body 1. Then, turn on the power of the drive motor 21. After the drive motor 21 is turned on, it drives the rotation of the ball screw 602. Due to the connection method of the ball screw 602 and the threaded sleeve, the circumferential rotation of the ball screw 602 drives the vertical lifting and lowering movement of the ball nut 601. The movement of the ball nut 601 drives the telescopic rod. 4. As the telescopic rod 4 moves downward along the extension of the sleeve rod 5, the right side of the platform 3 moves downward through the connection of the disc 18, the second movable rod 19, and the second bracket 20. At this time, the movement of the right side of the platform 3 causes the first bracket 8 to rotate on the first movable rod 9, allowing the lamp body 1 to be adjusted in angle. Finally, when the lamp body 1 is damaged and needs to be replaced, press the spring clip 2 to move it into the fixing block 16 until the spring clip 2 is separated from the through hole 15. Then the locking block 13 can be removed from the fixing block 16, thus achieving the disassembly of the lamp body 1. At the same time, by using the spring clip 2's rebound, the spring clip 2 is ejected from the inside of the fixing block 16 and from the inside of the through hole 15, thus achieving the connection between the spring clip 2 and the locking block 13 and the fixing block 16, achieving the installation effect of the lamp body 1.
