[0020] As Figures 1 to 4 shown, a power lighting bracket includes a disc base 1, a telescopic column 2 and a mounting bracket 3. One end of the telescopic column 2 is rotatably connected to the disc base 1, and the other end is fixedly connected to the mounting bracket 3. The telescopic column 2 rotates around its own axis. The shape of the mounting bracket 3 is U - shaped. A lighting lamp 4 is hinged inside the opening of the mounting bracket 3. The deflection axis of the lighting lamp 4 is horizontally arranged. The use height of the lighting lamp 4 is adjusted by the telescopic movement of the telescopic column 2. The telescopic column 2 can rotate on the disc base 1, so that the lighting lamp 4 can rotate 360° with the axis of the telescopic column 2 as the rotation axis to adjust the lighting position. Combining with the height adjustment of the lighting lamp 4, the lighting position of the lighting lamp 4 can be adjusted within a large range. By the deflection of the lighting lamp 4 itself, the lighting angle of the lighting lamp 4 is adjusted, so that the lighting angle can be adjusted in multiple angles, adapting to complex use environments, improving the power maintenance efficiency and reducing the manual labor intensity.

[0021] Furthermore, as Figure 2 shown, a hinge shaft 5 is horizontally arranged inside the opening of the mounting bracket 3. The hinge shaft 5 is rotatably connected to the mounting bracket 3. The lighting lamp 4 is mounted on the hinge shaft 5. The pitching angle of the lighting lamp 4 is adjusted by the rotation of the hinge shaft 5, thereby adjusting the lighting angle.

[0022] Furthermore, as Figure 2 shown, a mounting block 21 is fixed to the back of the lighting lamp 4. An installation opening 22 is formed at one end of the mounting block 21 away from the lighting lamp 4. The hinge shaft 5 is fitted inside the installation opening 22. A locking hole is penetrated through the side wall of the hinge shaft 5. A locking screw 23 is threadedly connected to the top of the mounting block 21. The tail of the locking screw 23 is fitted inside the locking hole. The lighting lamp 4 is detachably mounted on the hinge shaft 5, which is convenient for maintaining or replacing the lighting lamp 4. When disassembling, remove the locking screw 23, and then the lighting lamp 4 can be directly removed. When installing, the mounting block 21 is sleeved on the hinge shaft 5 through the installation opening 22 so that the locking hole corresponds to the locking screw 23, and then the locking screw 23 is tightened so that the tail of the locking screw 23 is fitted into the locking hole to complete the connection between the lighting lamp 4 and the hinge shaft 5, making the disassembly and assembly of the lighting lamp 4 simple and fast.

[0023] Furthermore, if Figure 1 and Figure 2 As shown, one end of the hinge shaft 5 passes through the mounting frame 3 and is fixed with a rotating disk 6, and the end of the rotating disk 6 away from the hinge shaft 5 is coaxially fixed with a rotating handle 7, and the side wall of the rotating disk 6 is evenly distributed with a plurality of limiting teeth 8 along its own circumferential direction, and a limiting groove 9 is formed between two adjacent limiting teeth 8. A limiting rod 10 is slidably provided on the side wall of the mounting frame 3, and the limiting rod 10 moves close to or away from the rotating disk 6. The limiting rod 10 is used to fit in the limiting groove 9 to limit the rotation of the rotating disk 6. The mounting frame 3 is horizontally provided with a slide groove 11, and a slider 12 is slidably adapted in the slide groove 11. A spring 13 is arranged in the slide groove 11, and the two ends of the spring 13 are respectively connected to the mounting frame 3 and the slider 12, and the limiting rod 10 is fixed on the slider 12. When the spring 1 When it is in the normal state, the limit rod 10 is adapted in the limit groove 9, and the deflection position of the hinge shaft 5 can be locked by the cooperation between the limit rod 10 and the rotating disk 6. Specifically, the limit rod 10 is pulled to make the limit rod 10 compress the spring 13 and move away from the rotating disk 6, so that the limit rod 10 is disengaged from the limit groove 9, and then the handle 7 is rotated to drive the hinge shaft 5 to rotate, so as to adjust the illumination angle of the illuminating lamp 4. When it is adjusted to the specified position, the limit rod 10 is released, and the position of the rotating disk 6 is fine-tuned, so that the limit rod 10 is adapted in the limit groove 9 under the reaction force of the spring 13, and the rotation of the rotating disk 6 is limited by the limit rod 10, thereby limiting the rotation of the hinge shaft 5, and ensuring the installation stability of the illuminating lamp 4.

[0024] Furthermore, if Figure 3 and Figure 4 As shown, the telescopic column 2 includes a rotating column 14 and a lifting column 15. One end of the rotating column 14 is rotatably connected to the disc base 1, and the other end is slidably penetrated by the lifting column 15. The end of the lifting column 15 away from the rotating column 14 is fixedly connected to the mounting frame 3. The side of the rotating column 14 close to the lifting column 15 is threadedly connected with a locking bolt 16. The locking bolt 16 penetrates into the rotating column 14 and presses against the lifting column 15. The length of the telescopic column 2 can be adjusted by loosening the locking bolt 16 and sliding the lifting column 15. After the adjustment is completed, the locking bolt 16 is tightened to lock the length of the telescopic column 2.

[0025] Furthermore, if Figure 4As shown, a small diameter hole 17 and a large diameter hole 18 are provided on the top of the disc base 1 from top to bottom in sequence, and a limit plate 19 is rotatably fitted in the large diameter hole 18.

An elastic friction sleeve 20 is fixedly sleeved on the rotating column 14. The elastic friction sleeve 20 is interference fitted in the small diameter hole 17 through compression deformation. The telescopic column 2 is rotated to overcome the friction force generated by the elastic friction sleeve 20 and rotate, thereby driving the lighting lamp 4 to rotate and completing the position adjustment of the lighting lamp 4. After the adjustment is in place, the telescopic column 2 is released, and the friction force generated by the elastic friction sleeve 20 stabilizes the deflection position of the telescopic column 2, thereby maintaining the stability of the position of the lighting lamp 4.
