Technical Field
[0001] This utility model belongs to the field of emergency lighting technology, specifically relating to a multi-angle adjustable fire emergency lighting fixture. Background Technology
[0002] Emergency lighting fixtures are a type of lighting equipment that effectively illuminates and displays evacuation routes when normal lighting power fails, or provides continuous illumination without interruption. They are widely used in public places and areas where uninterrupted lighting is unacceptable. Emergency lighting fixtures consist of several parts, including a light source, a light source driver, a rectifier, an inverter, a battery pack, and a marker light housing.
[0003] Existing devices primarily mount LED lights on a lightbox. Many existing technologies resemble adjustable-angle fire emergency lighting fixtures. The structure of device CN216408700U includes a main housing. A warning light is rotatably mounted on the top of the main housing via a mounting bracket. A connector is located at the rear of the warning light. A push rod is vertically mounted on a crossbar. The other end of the push rod extends out of the main housing and is hinged to a connecting rod, the other end of which is hinged to the connector. This invention allows for angle adjustment of the lighting fixture through an adjustment system, increasing the lighting area and enhancing the lighting effect. However, there are still areas for improvement in this device.
[0004] Existing devices primarily control the tilt angle of LED lights through adjustment mechanisms. This makes it difficult to regulate the horizontal orientation of a pair of LED lights, thus hindering control over the effective illumination range. Furthermore, some devices rely on ball joints to support the LED lights, making it difficult to adjust the tension of the ball joint. This makes it unsuitable for long-term stable support of tilted LED lights, reducing the device's efficiency and practicality. Therefore, a multi-angle adjustable fire emergency lighting fixture is urgently needed to solve these problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] This utility model provides a multi-angle adjustable fire emergency lighting fixture as shown in the figure, including a light box 11. A power plug 12 is fixedly connected to the right side of the light box 11. A control panel 13 is provided on the front right side of the light box 11. A transmission box 14 is fixedly connected to the top center of the light box 11. An adjustment mechanism 2 is provided inside the transmission box 14. A ball cage universal joint 15 is provided above the transmission box 14. A tensioning mechanism 3 is provided inside the ball cage universal joint 15. An LED light 16 is fixedly connected to the top of the ball cage universal joint 15. A power supply line 17 is fixedly connected to the rear side of the LED light 16. The other end of the power supply line 17 is fixedly connected to both sides of the top of the light box 11.
[0023] The adjustment mechanism 2 includes a servo motor 21. The bottom of the servo motor 21 is fixedly connected to the top center of the transmission box 14. A transmission shaft 22 is fixedly connected to the bottom center of the servo motor 21. The bottom end of the transmission shaft 22 passes through the transmission box 14 and is fixedly connected to a first bevel gear 23. This design enables the servo motor 21 to drive the transmission shaft 22 and the first bevel gear 23 to rotate in a limited position. A second bevel gear 24 is meshed with the lower right side of the first bevel gear 23. A symmetrical worm gear 25 is fixedly connected to the inner wall of the second bevel gear 24. The two ends of the symmetrical worm gear 25 are movably connected to both sides of the inner wall of the transmission box 14. This design enables the first bevel gear 23 to mesh and drive the second bevel gear 24 and the symmetrical worm gear 25 to rotate in a limited position. A transmission worm wheel 26 is meshed with both sides of the outer wall of the symmetrical worm gear 25. A rotating rod 27 is fixedly connected to the inner wall of the transmission worm wheel 26. The bottom end of the rotating rod 27 is movably connected to the top of the light box 11. This design enables the symmetrical worm gear 25 to mesh and drive a pair of transmission worm wheels 26 and rotating rod 27 to rotate synchronously in opposite directions. This allows the rotating rod 27 to drive the ball cage universal joint 15 and LED lights 16 to rotate synchronously, making it easier to control the effective lighting range of the pair of LED lights 16.
[0024] The tensioning mechanism 3 includes a ball sleeve 31. The top end of the rotating rod 27 passes through the transmission box 14 and is fixedly connected to the bottom of the ball sleeve 31. A rubber pad 32 is fixedly connected to the bottom of the inner wall of the ball sleeve 31. The inner wall of the rubber pad 32 is tightly attached to the ball shaft 33. The top of the ball shaft 33 is fixedly connected to the bottom of the LED light 16. Through this design, the ball shaft 33 drives the LED light 16 to rotate in a limited position, which facilitates the control of the downward angle of the LED light 16. The rubber pad 32 is tightly attached to the ball shaft 33, so that the ball shaft 33 drives the LED light 16 to remain stable after adjustment. A fastening screw sleeve 34 is fitted on the upper part of the outer wall of the ball shaft 33. Torsion plates 35 are fixedly connected to both sides of the outer wall of the fastening screw sleeve 34. The lower part of the inner wall of the fastening screw sleeve 34 is fitted on the upper part of the outer wall of the ball sleeve 31. A thread 36 corresponding to the fastening screw sleeve 34 is opened on the upper part of the outer wall of the ball sleeve 31. This design enables the manual rotation of the torsion plate 35, which drives the fastening nut 34 to spiral up and down along the thread 36 on the outer wall of the ball sleeve 31, thereby tightening or loosening the ball shaft 33 by the fastening nut 34 in conjunction with the ball sleeve 31.
[0025] Working principle: When it is necessary to adjust the LED light 16, the servo motor 21 is first started through the control panel 13. The servo motor 21 drives the transmission shaft 22 to rotate in a limited position. The transmission shaft 22 drives the first bevel gear 23 to rotate synchronously. The first bevel gear 23 meshes and drives the second bevel gear 24 to rotate. The second bevel gear 24 drives the symmetrical worm gear 25 to rotate in a limited position. The symmetrical worm gear 25 meshes and drives a pair of transmission worm wheels 26 to rotate synchronously in opposite directions. The transmission worm wheels 26 drive the rotating rod 27 to rotate in a limited position. The rotating rod 27 drives the ball cage universal joint 15 and the LED light 16 to rotate synchronously, thus realizing the adjustment operation of the LED light 16.
[0026] When it is necessary to tighten or loosen the ball cage universal joint 15, firstly, manually rotate the torsion plate 35. The torsion plate 35 drives the fastening nut 34 to rotate synchronously, so that the fastening nut 34 moves up and down along the thread 36 on the outer wall of the ball sleeve 31. The fastening nut 34, together with the ball sleeve 31 and the rubber pad 32 inside it, loosens or loosens the clamping force of the ball shaft 33, thus realizing the tightening or loosening operation of the ball cage universal joint 15. The operation ends here.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
