Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1: Please refer to Figures 1 - 4 , an angle-adjustable LED bulb, including a mounting frame 5. Both sides of the bottom end of the mounting frame 5 are fixedly connected with connecting plates 4. A mounting block 2 is arranged at the bottom end between the connecting plates 4. The bottom end of the mounting block 2 is provided with a bulb body 1. A regulating structure is installed on the left side of the connecting plate 4;

[0026] The regulating structure includes a servo motor 3, a ball 16 and a connecting shaft 19. A servo motor 3 is installed on the left side of the connecting plate 4. The output end of the servo motor 3 is fixedly connected with a connecting shaft 19. A reserved groove 10 is opened at the bottom end inside the connecting plate 4. Rolling grooves 15 are opened at the upper and lower ends inside the reserved groove 10. Balls 16 are arranged inside the rolling grooves 15;

[0027] Inside the mounting bracket 5, there is a fixed block 9. At the top of the fixed block 9, there is a connecting block 7 fixedly connected. At the top of the connecting block 7, there is a mounting plate 6. On both sides and at both ends inside the mounting plate 6, there are respectively mounting grooves 8. On both sides of the connecting shaft 19, they are inside the reserved groove 10, and the balls 16 roll inside the rolling grooves 15.

[0028] Specifically, as Figure 1 and Figure 4 shown, when the angle needs to be adjusted, start the servo motor 3. The servo motor 3 drives the mounting block 2 to rotate through the connecting shaft 19, so that the angle of the lamp body 1 can be adjusted. Since the connecting shaft 19 is arranged inside the reserved groove 10 and the balls 16 are arranged inside the rolling grooves 15, when the connecting shaft 19 rotates, the balls 16 can reduce the wear between the connecting shaft 19 and the reserved groove 10. It can not only facilitate the rotation of the connecting shaft 19 but also increase the service life of the connecting shaft 19.

[0029] Embodiment 2: On the right side at the bottom of the mounting bracket 5, there is a hydraulic cylinder 22 fixedly connected. At the bottom of the hydraulic cylinder 22, there is a bottom plate 21 fixedly connected. The bottom plate 21 is fixedly connected with a limiting block 20. On the right side outside the connecting shaft 19, there is a limiting disc 17 fixedly connected. On the outer side wall of the limiting disc 17, there are limiting holes 18. There are multiple groups of limiting holes 18, and the limiting holes 18 are arranged at equal intervals on the outer side wall of the limiting disc 17. The limiting block 20 is embedded inside the limiting hole 18, and the limiting block 20 and the limiting hole 18 cooperate with each other.

[0030] Specifically, as Figure 1 and Figure 4 shown, after adjustment, start the hydraulic cylinder 22. The hydraulic cylinder 22 drives the limiting block 20 to descend through the bottom plate 21, so that the limiting block 20 is embedded inside the limiting hole 18, and thus the connecting shaft 19 can be limited and fixed through the limiting disc 17, preventing the connecting shaft 19 from accidentally driving the lamp body 1 to rotate through the mounting block 2 and affecting the use of the lamp body 1.

[0031] Embodiment 3: On both sides of the mounting bracket 5, there are pull plates 14. On the side of the pull plate 14 close to the middle, there is a limiting rod 11 fixedly connected. Between the mounting bracket 5 and the pull plate 14, there is a spring 13 fixedly connected. On both sides inside the mounting bracket 5 and the fixed block 9, there are limiting grooves 12. The limiting rod 11 is embedded inside the limiting groove 12, and the spring 13 is arranged on one side outside the limiting rod 11.

[0032] Specifically, as Figure 1 and Figure 4As shown, when the bulb body 1 and the mounting block 2 need to be mounted at the bottom end of the mounting plate 6, the pull plate 14 is pulled. The pull plate 14 drives the limit rod 11 to move into the limit groove 12. Then, the mounting bracket 5 is clamped outside the fixed block 9 and slides outside the fixed block 9. After sliding to the appropriate position, the pull plate 14 is released. The spring 13 makes the limit rod 11 fit into the limit groove 12 by its own elasticity to limit and fix the mounting bracket 5, so that the mounting bracket 5 is mounted on the top of the fixed block 9.

[0033] Working principle: When the present utility model is in use, when the bulb body 1 and the mounting block 2 need to be mounted at the bottom end of the mounting plate 6, the pull plate 14 is pulled. The pull plate 14 drives the limit rod 11 to move into the limit groove 12. Then, the mounting bracket 5 is clamped outside the fixed block 9 and slides outside the fixed block 9. After sliding to the appropriate position, the pull plate 14 is released. The spring 13 makes the limit rod 11 fit into the limit groove 12 by its own elasticity to limit and fix the mounting bracket 5, so that the mounting bracket 5 is mounted on the top of the fixed block 9. When the angle needs to be adjusted, the servo motor 3 is started. The servo motor 3 drives the mounting block 2 to rotate through the connecting shaft 19, so that the angle of the bulb body 1 can be adjusted. When the connecting shaft 19 rotates, the ball 16 can reduce the wear between the connecting shaft 19 and the reserved groove 10, which can not only facilitate the rotation of the connecting shaft 19 but also increase the service life of the connecting shaft 19. After adjustment, the hydraulic cylinder 22 is started. The hydraulic cylinder 22 drives the limit block 20 to descend through the bottom plate 21, so that the limit block 20 fits into the limit hole 18, so that the connecting shaft 19 can be limited and fixed by the limit disc 17, preventing the connecting shaft 19 from accidentally driving the bulb body 1 to rotate through the mounting block 2 and affecting the use of the bulb body 1.

[0034] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
