It allows for height adjustment and activation of the lighting equipment according to work needs, and can retract and protect the lighting equipment according to weather conditions, thus demonstrating strong practicality.

[0004] However, while this type of lighting device can provide good illumination for the construction area, it also has drawbacks when illuminating the area, as the front and back positions of the construction area may differ. Furthermore, the single mounting bracket typically uses only a single light for illumination, which is not very effective for switching between unidirectional and interdirectional use of the lights. Additionally, the installation and removal of the lights are not very efficient, reducing the efficiency of daily maintenance.

[0005] Therefore, in view of this, we have studied and improved the existing structure to propose a construction site lighting device that is easy to assemble and disassemble. Summary of the Invention

[0006] The purpose of this utility model is to provide a construction site lighting device that is easy to assemble and disassemble, in order to solve the problems mentioned in the background art, such as the different front and back positions of the construction area, and the fact that a single mounting frame is usually used for lighting operation by a single lighting lamp, which is not very effective for using the lighting lamp in the same direction or switching between opposite directions, and the effect of locking and disassembling the lighting lamp is not very good, thus reducing the efficiency of daily maintenance of the lighting lamp.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a construction site lighting device that is easy to assemble and disassemble, comprising a connecting frame, a sliding box slidably connected to the outer wall of the connecting frame, a first servo motor disposed on the outer wall of the connecting frame, a bevel gear set rotatably connected to the inner wall of the connecting frame fixedly connected to the output end of the first servo motor, a threaded rod rotatably connected to the outer wall of the bevel gear set fixedly connected to the outer wall of the connecting frame, a fixing groove provided at the connection between the outer wall of the connecting frame and the sliding box, a second servo motor disposed on the outer wall of the sliding box, a worm gear rotatably connected to the inner wall of the sliding box fixedly connected to the output end of the second servo motor, a worm wheel rotatably connected to the inner wall of the sliding box meshing with the outer wall of the worm gear, a fixing frame fixedly connected to the rotation center of the worm wheel via a rotating shaft, a mounting frame engaging with the outer wall of the fixing frame, and a lighting lamp body rotatably connected to the outer wall of the mounting frame.

[0009] Furthermore, the threaded rod and the sliding box are connected by a thread, and there are two sets of threaded rods with opposite rotation directions.

[0010] Furthermore, the sliding box forms a sliding structure with the fixed groove through the bevel gear set and the threaded rod, and the sliding box and the threaded rod are arranged in a one-to-one correspondence.

[0011] Furthermore, the fixed frame forms a rotating structure with the sliding box through a worm and a worm wheel, and the rotation center of the worm wheel and the rotation center of the fixed frame are mutually coincident.

[0012] Furthermore, the inner wall of the fixing frame is provided with a slot at the connection point between it and the mounting frame.

[0013] Furthermore, a connecting groove is provided at the connection point between the outer wall of the mounting bracket and the connecting rod.

[0014] Furthermore, the outer wall contour of the pressing part of the connecting rod and the telescopic rod is inclined, while the outer wall contour of the loosening pressing part of the connecting rod and the telescopic rod is flat.

[0015] Furthermore, the connecting box is provided in two sets, and the positions of the two sets of connecting boxes are symmetrical about the central axis of the fixing frame.

[0016] Furthermore, the telescopic rod forms a telescopic structure with the connecting rod and the telescopic rod and the connecting box.

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.

[0029] Example 1:

[0030] As shown in Figures 1-6, a construction site lighting device that is easy to assemble and disassemble includes a connecting frame 1. A sliding box 2 is slidably connected to the outer wall of the connecting frame 1. A first servo motor 3 is provided on the outer wall of the connecting frame 1. A bevel gear set 4, which is rotatably connected to the inner wall of the connecting frame 1, is fixedly connected to the output end of the first servo motor 3. A threaded rod 5, which is rotatably connected to the inner wall of the connecting frame 1, is fixedly connected to the outer wall of the bevel gear set 4. A fixing groove 6 is provided at the connection between the outer wall of the connecting frame 1 and the sliding box 2. A second servo motor 7 is provided on the outer wall of the sliding box 2. A worm gear 8, which is rotatably connected to the inner wall of the sliding box 2, is fixedly connected to the output end of the second servo motor 7. A worm wheel 9, which is rotatably connected to the inner wall of the sliding box 2, is meshed with the outer wall of the worm gear 8. A fixing frame 10 is fixedly connected to the rotation center of the worm wheel 9 through a rotating shaft. A mounting frame 12 is snapped onto the outer wall of the fixing frame 10. A lighting lamp body 13 is rotatably connected to the outer wall of the mounting frame 12.

[0031] As shown in Figures 2-6, a connecting box 11 is fixedly connected to the outer wall of the fixing frame 10, a connecting rod 14 is fixedly connected to the outer wall of the mounting frame 12 and is slidably connected to the outer wall of the connecting box 11, a telescopic rod 15 is engaged with the outer wall of the connecting rod 14 and is slidably connected to the inner wall of the connecting box 11, a telescopic rod 16 is fixedly connected to the outer wall of the telescopic rod 15 and is slidably connected to the outer wall of the connecting box 11, a spring 17 is sleeved on the outer wall of the telescopic rod 16 and is fixedly connected to the outer wall of the connecting box 11, and a pull block 18 is fixedly connected to one end of the spring 17 and is fixedly connected to one end of the telescopic rod 16.

[0032] As shown in Figure 3, the threaded rod 5 and the sliding box 2 are connected by a thread. There are two sets of threaded rods 5, and the rotation directions of the two sets of threaded rods 5 are opposite. This is beneficial to the convenient sliding of the sliding box 2 by the threaded connection between the threaded rod 5 and the sliding box 2.

[0033] As shown in Figure 3, the sliding box 2 forms a sliding structure with the fixed groove 6 through the bevel gear set 4 and the threaded rod 5. The sliding box 2 and the threaded rod 5 are set in a one-to-one correspondence, which is conducive to the rotation of the bevel gear set 4. Through the connection of the threaded rod 5, the sliding box 2 is driven to slide along the inner wall of the fixed groove 6, which plays a role in conveniently adjusting the spacing of the lighting lamp.

[0034] As shown in Figure 4, the fixed frame 10 forms a rotating structure with the sliding box 2 through the worm 8 and worm wheel 9. The rotation center of the worm wheel 9 and the rotation center of the fixed frame 10 are set to coincide with each other, which is conducive to the rotation of the worm 8. Through the connection of the worm wheel 9, the fixed frame 10 is driven to rotate along the top of the sliding box 2, which can conveniently adjust the illumination angle of the lighting lamp.

[0035] As shown in Figure 5, a slot is provided at the connection between the inner wall of the fixing frame 10 and the mounting frame 12, which facilitates the pre-installation of the mounting frame 12.

[0036] As shown in Figure 6, a connecting groove is provided at the connection point between the outer wall of the mounting bracket 12 and the connecting rod 14. This facilitates the pre-installation and use of the connecting rod 14 by providing a connecting groove at the connection point between the outer wall of the mounting bracket 12 and the connecting rod 14.

[0037] As shown in Figure 6, the outer wall contour of the pressing part of the connecting rod 14 and the telescopic rod 15 is inclined, while the outer wall contour of the loosening pressing part of the connecting rod 14 and the telescopic rod 15 is flat. This design, with the outer wall contour of the pressing part of the connecting rod 14 and the telescopic rod 15 being inclined, facilitates the locking and installation of the lighting lamp.

[0038] As shown in Figures 1-4, there are two sets of connecting boxes 11. The positions of the two sets of connecting boxes 11 are symmetrical about the central axis of the fixing frame 10. This arrangement helps to improve the stability of the lighting fixture during installation and use.

[0039] As shown in Figure 6, the telescopic rod 16 forms a telescopic structure with the connecting box 11 through the connecting rod 14 and the telescopic rod 15. This facilitates the sliding of the telescopic rod 16 along the outer wall of the connecting box 11 by the squeezing movement of the connecting rod 14 on the telescopic rod 15, thus enabling convenient disassembly and assembly of the lighting lamp.

[0040] Working principle: When using this easy-to-assemble and disassemble construction site lighting device, firstly, the threaded rod 5 drives the sliding box 2 to change the spacing, which facilitates the adjustment of the lighting range of the two sets of lights. At the same time, the rotation of the worm gear 8 and worm wheel 9 drives the lighting angle of the lights to change, so that the two sets of lights on the same connecting frame 1 can switch lighting operations to different positions, improving the multi-functionality of the lighting on the construction site.

[0041] Finally, by engaging the connecting rod 14 and the telescopic rod 15, the connecting rod 14 is inserted into the connecting box 11, which engages and fixes the mounting bracket 12 and the fixing bracket 10, thus achieving the effect of convenient disassembly and assembly of the lighting lamp.

[0042] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
