[0002] Track lights are a common lighting and decorative structure, consisting of a track light power supply and a lamp body connected to the power supply. The track light power supply is mainly used to draw power from the track and is mostly a strip-shaped integral structure. Although it can meet general usage needs, it is fixed after assembly and cannot be rotated or adjusted as needed. The lamp body is connected to the track light power supply through a lamp arm, which can only achieve angle adjustment and cannot meet the lighting needs of different directions, thus limiting its applicability.

Detailed Implementation

[0023] 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.

[0024] Example

[0025] See Figures 1 to 4 As shown, a rotary adjustable track light power supply includes a track box 1 and a power supply box 2. In this embodiment, the power supply box is connected to the light arm, and the track box is inserted into the track for power connection. These are conventional structures in the prior art, so they are not described in detail.

[0026] In this embodiment, the track box includes a base box 11 and a cover 12 fixed by screws. A power-feeding contact 13 is provided on the side wall of the base box, and a limiting block 15 is provided at the end of the cover via a spring 14. This structure is a conventional structure in the prior art and is therefore not described in detail. When the track box is inserted into the track, power is drawn through the power-feeding contact, and the spring, in conjunction with the limiting block, achieves limiting. A magnet 3 is embedded in the center of the top surface of the cover. It can be magnetically connected to the track, achieving a dual connection.

[0027] A circular through hole 4 is provided in the middle of the bottom wall of the base box. A pressure plate 5 is fixed to the top surface of the bottom wall of the base box by screws. A ring body 6 is snapped in the center of the pressure plate. A limiting protrusion 7 is integrally formed on the inner ring edge of the ring body. A wire-passing hole post 8 is fixed to the top of the power box. The pressure plate is a plastic structure, while the wire-passing hole post and the ring body are metal structures. The above structure can ensure stable use and service life and prevent damage. A stop protrusion 9 is integrally formed on the inner edge of the top surface of the wire-passing hole post. The wire-passing hole post is rotatably connected to the circular through hole. The ring body is attached to the top surface of the wire-passing hole post, and the stop protrusion is on the rotation trajectory of the limiting protrusion. When the ring body rotates on the wire-passing hole post, the limiting stop block stops against the side of the limiting protrusion. With the above structure, the abutment protrusion and the limiting protrusion can be used to rotate and limit the wire, preventing damage to the wire due to excessive rotation. It can also achieve rotation within a range of 350 degrees, which can meet the needs of use in different directions. The wire can be rotated between the wire hole post and the center of the ring.

[0028] Furthermore, in this embodiment, the threading post is connected within the circular through hole via a bearing or a retaining spring. This structure ensures the normal rotation and connection of the threading post, preventing loosening or detachment.

[0029] Furthermore, in this embodiment, a positioning protrusion 10 is integrally formed on the outer wall of the annular body; a positioning groove 16 that mates with the positioning protrusion is provided on the pressure plate; during assembly, the annular body is inserted into the pressure plate and the positioning protrusion is engaged in the positioning groove for positioning. This structure ensures the stability and reliability of the connection between the annular body and the pressure plate.

[0030] In this embodiment, the power-taking contact piece is electrically connected to the power supply box via a wire 17, and the wire passes through the through-hole post. The symmetrical edges of the pressure plate are integrally formed with mounting ears 18, which are attached to the bottom wall of the base box and fixed with screws. This structure improves the convenience and effectiveness of pressure plate assembly, facilitating inspection and maintenance.

[0031] This utility model has positive effects: its structure is reasonably designed, and its power box is rotatably connected to the track box through a wire-through hole post. With the help of the ring body on the track box, a limiting protrusion on the inner edge of the ring body, and a stop protrusion on the wire-through hole post, the power box can rotate on the track box. The rotation is limited by the limiting protrusion and the stop protrusion, which can achieve 350-degree rotation. The rotation adjustment is convenient and can meet the needs of different situations. It is conducive to improving the stability and reliability of the overall structure and has strong applicability.

[0032] 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.

[0033] 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.
