[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A novel background light power cord includes a background light body 1, a power cord body 2, and a plug 3. The background light body 1 is existing technology and can be installed on a wall, ceiling, or floor to create ambient lighting. The plug 3 connects to a power source to supply power to the background light body 1 for illumination. This is existing technology and will not be elaborated upon further. A retractable winding post 4 is connected to the bottom of the background light body 1. The power cord body 2 is wound around the winding post 4, which has a telescopic groove 5. A fixed connection is made to the bottom of the background light body 1. T-shaped connecting rod 6 extends into telescopic slide 5 and slides therein. T-shaped connecting rod 6 is adapted to telescopic slide 5 so that winding post 4 can only slide vertically. Multiple springs 7 are connected between T-shaped connecting rod 6 and the inner top of telescopic slide 5. Springs 7 are elastic springs. In a natural state, they can push winding post 4 upward so that winding post 4 fits against the bottom of background lamp body 1. Power cord body 2 passes through the bottom of background lamp body 1. A winding groove is opened on the outer wall of winding post 4, and power cord body 2 is wound in the winding groove.

[0024] The bottom of the backlight body 1 is fixedly connected to a protective cover 8 that covers the outside of the winding post 4. The protective cover 8 has multiple through holes 9 arranged in a ring array. The power cord body 2 is inserted into the corresponding through hole 9. The power cord body 2 can be inserted into different through holes 9 so that it can pass out from different directions to meet different installation and use requirements. The protective cover 8 is threadedly connected to a cover 10. The through holes 9 are opened through the protective cover 8 and form an opening at the bottom of the protective cover 8. The outer side wall of the protective cover 8 has external threads, and the inner side wall of the cover 10 has internal threads. The cover 10 is threadedly connected to the protective cover 8 and can seal the bottom of the protective cover 8 to prevent the power cord body 2 from falling out of the corresponding through hole 9.

[0025] The cover 10 is detachably threaded with an adsorption assembly for adsorbing and fixing the backlight body 1. The adsorption assembly includes a connecting plate 11 detachably threaded to the bottom of the cover 10. The bottom of the cover 10 has an internal threaded groove. The connecting plate 11 is cylindrical and has external threads on its outer side wall. The connecting plate 11 is threaded into the internal threaded groove, making it easy to install or remove the connecting plate 11 from the bottom of the cover 10. A suction cup 12 is installed at the bottom of the connecting plate 11. The suction cup 12 facilitates adsorbing the backlight body 1 onto a smooth wall or other smooth surface. An air storage cavity 13 is provided on the connecting plate 11, and the air storage cavity 13 is interconnected with the suction cup 12. The disks 12 are connected by an air supply pipe. A sealing plate 14 is slidably connected inside the air storage chamber 13. A threaded rod 15 is rotatably connected to the side wall of the sealing plate 14. The threaded rod 15 is threaded through the side wall of the air storage chamber 13 and extends to the outside of the connecting plate 11. A threaded opening is provided on the connecting plate 11 that communicates with the air storage chamber 13. The threaded rod 15 passes through the threaded opening and is threadedly connected to it. A rotating handle is provided on the side wall of the threaded rod 15. The rotating handle facilitates the rotation of the threaded rod 15. When the threaded rod 15 rotates, it can drive the sealing plate 14 to move left and right under its meshing action with the threaded opening, thereby extracting air from the air storage chamber 13 and enabling the suction cup 12 to be stably adsorbed on the wall.

[0026] The functional principle of this utility model can be explained through the following operation methods:

[0027] In this utility model, when the power cord of the background light is in use, the plug 3 is connected to the power supply, which enables the background light body 1 to be powered on for lighting. When the power cord body 2 is in a loose state and is long, the cover 10 is unscrewed, and the winding post 4 is pulled outward to move it to the bottom of the protective cover 8, so that the power cord body 2 can be wound into the winding groove on the winding post 4. According to the installation position of the power supply and the background light body 1, the power cord body 2 is inserted into the corresponding wire hole 9 at the bottom of the protective cover 8, so that the power cord body 2 passes through the protective cover 8. The winding post 4 is released, and under the pulling force of the spring 7, the winding post 4 can slide upward to fit against the bottom of the background light body 1. The cover 10 is screwed to the bottom of the protective cover 8 to protect the power cord body 2 and prevent it from falling out of the corresponding wire hole 9. The power cord body 2 is stored in the protective cover 8, which can ensure its aesthetics and reduce the phenomenon of tangling when exposed.

[0028] When the background light body 1 needs to be installed on the wall, screw the connecting plate 11 to the bottom of the cover 10, and rotate the threaded rod 15 so that it drives the sealing plate 14 to move left and right under the action of the threaded engagement with the threaded opening. When the sealing plate 14 moves to the left away from the suction cup 12, it can extract the air between the suction cup 12 and the wall, so that the suction cup 12 can be stably attached to the wall, and the background light body 1 can be installed on the wall. When the sealing plate 14 moves to the right and closer to the suction cup 12, it can push the air in the air storage chamber 13 into the suction cup 12, so that the suction cup 12 and the wall are filled with air, and the suction cup 12 can be separated from the wall, and the background light body 1 can be removed. Similarly, the background light body 1 can also be installed in other positions where it is needed. At the same time, the connecting plate 11 and the bottom thread of the cover 10 are detachably connected, and the connecting plate 11 can also be removed for storage to meet different usage needs.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
