[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] Example

[0030] See Figures 1 to 4 As shown, a lifting lamp structure includes a mounting base 1, two suspension wires 2 and a lamp body 3. The bottom ends of the two suspension wires are fixed to the two ends of the top surface of the lamp body. In this embodiment, the above structure is a conventional structure of the prior art, and it is simply applied, so it is not described in detail.

[0031] Furthermore, in this embodiment, the mounting base is equipped with a drive motor 4, a drive circuit board 5, a drive shaft 6, and two stranded wire wheels 7. In this embodiment, the drive circuit board is a conventional structure of the prior art, and is simply applied, so it is not described in detail. During assembly, the drive motor is fixed in the mounting base and connected to the middle of the drive shaft through a reduction gearbox 8. The mounting base is provided with several brackets 9, the drive shaft is rotatably connected to the brackets, and the stranded wire wheels are fixed at both ends of the drive shaft. The top ends of the two suspension wires are fixed on the stranded wire wheels. The drive end of the drive circuit board is connected to the drive motor, and a drive power supply 13 is fixed in the mounting base. The ends of the two stranded wire wheels are respectively provided with positive terminals 17 and negative terminals 18 connected to the drive power supply, and the two suspension wires are respectively connected to the positive terminals and negative terminals. When the drive motor is started, it drives the drive shaft to rotate, and the suspension wires on the stranded wire wheels are wound or unwound to realize the raising and lowering of the lamp body. With the above structure, when the drive motor starts, it will drive the drive shaft to rotate through the reduction gearbox. The drive shaft will then drive the two stranded wire wheels to rotate synchronously, thereby causing the two suspension wires to wrap around or unwrap from the stranded wire wheels synchronously, realizing the synchronous lifting and lowering of both ends of the lamp body. This allows for easy operation and stable and reliable use.

[0032] Furthermore, in this embodiment, two limit switches 10 connected to the drive circuit board are fixed on the mounting base; an externally threaded tube 11 is fixed on the drive shaft, and a limit contact 12 is screwed onto the externally threaded tube, with the limit contact 12 positioned between the two limit switches; the gearbox drives the externally threaded tube to rotate, at which time the limit block translates on the externally threaded tube and abuts against the upper limit of the limit switch. Additionally, a guide groove is provided on the mounting base, with the two limit switches located at opposite ends of the guide groove, and the end of the limit contact 12 positioned within the guide groove. Through this structure, when the externally threaded tube rotates with the gearbox, the limit contact 12 translates on the externally threaded tube and is limited by one of the limit switches, thus limiting the lifting height.

[0033] In practical applications, a remote control signal receiver 14 is fixed inside the mounting base; during assembly, both the drive power supply and the remote control signal receiver are connected to the drive circuit board. This enables stable power supply and remote control operation.

[0034] In this embodiment, the stranding wheel is a plastic structure. The mounting base has an oblong mounting slot 15. The surface of the stranding wheel is provided with several annular grooves 16. This improves the ease of assembly and the stability of the lifting and lowering of the wire.

[0035] This utility model has positive effects: The structure of this utility model is reasonable. It is equipped with a drive motor, a drive circuit board, a drive shaft and two stranded wheels in the mounting base. The two suspension lines are fixedly connected to the two stranded wheels respectively. Therefore, in use, the suspension lines can be raised and lowered by the drive motor as needed, thereby realizing the convenience and effectiveness of raising and lowering the lamp body. It is easy to adjust the height and can meet the needs of different situations, and has strong applicability.

[0036] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
