[0027] 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.

[0028] Example

[0029] See Figures 1 to 4 As shown, a lamp structure with universal connectors includes several lamp bodies 1 with identical structures, and several universal connectors 3. Adjacent lamp bodies are connected by universal connectors. In practical applications, the lamp bodies are downlights, spotlights, or other common lamp structures. In this embodiment, the lamp body includes a housing 11, a heat sink 12 fixed inside the housing, a light source plate 13 fixed to the bottom surface of the heat sink, and a lens 14. The side wall of the housing is provided with connection holes 15. The housing is a cylindrical housing, and the heat sink, light source plate, and lens are all conventional structures in the prior art, so they are not described in detail.

[0030] In this embodiment, the universal joint connector includes a mounting base 31, a lamp holder 32, a connecting base 33, at least two hollow ball joint rods 34, a ball joint seat 35, and a limiting cover 36. The mounting base is primarily used for installation on walls, ceilings, rod-shaped structures, or other plate-shaped structures. The mounting base, lamp holder, and connecting base are stacked sequentially and fixed by screws. The number of screws can be one, two, or more. The side wall of the connecting base is provided with at least two interconnected mounting... The ball head seat is fixed inside the mounting cavity 4. In this embodiment, the inner wall of the mounting cavity is threaded, and the ball head seat can be connected to the mounting cavity via a threaded connection. Furthermore, the end face of the ball head seat is provided with a hemispherical recess 5. During assembly, the hollow ball head rod passes through the limiting cover, and the ball head 2 is rotatably connected to the hemispherical recess. The limiting cover is threaded onto the hollow ball head rod and cooperates with the hemispherical recess to limit the ball head. The outer diameter of the ball head matches the inner diameter of the hemispherical recess. The lamp body is fixed to the end of the hollow ball head rod, and the power lines of adjacent lamp bodies pass through the hollow ball head rod and the connecting seat to achieve electrical connection.

[0031] The above structure not only enables the connection and positioning of adjacent lamp bodies, but also allows for adjustment in different directions or angles during use. The adjustable position is then secured by the limiting cover, ensuring stability and reliability. The hollow ball joint also facilitates the wiring connection between adjacent lamp bodies, improving the effectiveness and convenience of the connection. The end of the hollow ball joint is fixed within the connection hole in the housing. Threaded connections or snap-fit ​​connections can be used.

[0032] In this embodiment, an annular groove 6 is provided on the outer surface of the ball head of the hollow ball head rod, and an annular washer 7 is provided in the annular groove; the ball head is adjusted in the hemispherical cavity and limited by compression by the annular washer. The annular washer can increase the friction between the ball head and the inner wall of the hemispherical cavity without affecting the normal angle and direction adjustment operation, and at the same time, it can also ensure the stability and reliability of the adjusted position.

[0033] In this embodiment, the mounting base has snap-fit ​​mounting grooves 8 on its symmetrical edges; the bottom wall of the mounting base has mounting through holes 9, and the screw passes through the mounting through holes. This facilitates installation and operation.

[0034] Furthermore, in this embodiment, the connecting seat has two mounting cavities, and the two mounting cavities are located at both ends of the diameter of the connecting seat.

[0035] This utility model has positive effects: The structure of this utility model is reasonably designed. It can realize the splicing and connection of the lamp body through the universal connector, and the position and angle of the lamp body can be adjusted through the universal connector, thereby meeting the connection requirements of different shapes, improving the convenience of connection and the effectiveness of adjustment, meeting the usage needs of different situations, and the overall structure is stable and reliable after adjustment, with 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.
