DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] See Figures 1 to 2 As shown, a slide-rail adjustable downlight structure includes a heat sink 1, a light source board, a dimming cup 2, and a face ring 3. The light source board is fixed to the bottom surface of the heat sink. In this embodiment, the heat sink, light source board, dimming cup, and face ring are all conventional structures in the prior art, and the light source board is fixed to the bottom surface of the heat sink by screws.

[0031] In this embodiment, there are two symmetrically arranged slide rail adjustment components 4 between the dimming cup and the radiator, and the slide rail adjustment components include two locking marbles 41, a lower arc slide rail 42 and an upper arc slide rail 43; in this embodiment, the widths of the upper arc slide rail and the lower arc slide rail are both greater than the diameters of the locking marbles, so the positions of the two locking marbles in the upper arc slide rail and the lower arc slide rail are different, and the pitch angle adjustment within a small range can also be achieved; and at the same time as the direction adjustment, the positions of the two locking marbles in the upper arc slide rail and the lower arc slide rail are different, that is, the upper arc slide can be adjusted with the marbles in the lower arc slide rail as the fulcrum. The locking marbles in the rails are adjusted to a certain angle, so that the pitch angle adjustment of the dimming cup within a small range can be achieved. In this embodiment, the locking marbles are a conventional structure of the prior art. Under the action of the spring, the friction between the locking marbles and the lower arc slide rail and the upper arc slide rail will be relatively large. The friction between the locking marbles and the lower arc slide rail and the upper arc slide rail can be used to adjust the position after adjustment. During adjustment, it will only shift when the external force is greater than the friction between the locking marbles and the lower arc slide rail and the upper arc slide rail. Therefore, after adjustment, the friction of the locking marbles can be used to limit the position, thereby ensuring stability after adjustment.

[0032] During assembly, the two locking marbles are located in the upper and lower arc-shaped rails, respectively, and the dimming cup is adjusted by sliding the locking marbles in the upper and lower arc-shaped rails. This not only achieves an installation limit connection, thereby reducing the installation limit structure and improving the convenience and effectiveness of assembly, but also the locking marbles can slide simultaneously in the upper and lower arc-shaped rails, thereby facilitating the directional adjustment between the radiator and the dimming cup. At the same time, the face ring is sleeved on the outside of the dimming cup and can be rotated for adjustment. A plurality of arched adjustment limit grooves 12 are provided on the inner wall of the upper arc-shaped rail. After adjustment, the locking marbles are snapped into different arched adjustment limit grooves to limit the position, ensuring the effectiveness and reliability of the adjustment.

[0033] In this embodiment, the two locking marbles are fixed on the outer wall of the radiator and the two locking marbles are on the same vertical line; and the upper arc-shaped slide rail and the lower arc-shaped slide rail are on the inner wall of the dimming cup, and the upper arc-shaped slide rail is directly above the lower arc-shaped slide rail; during assembly, the dimming cup is mounted on the radiator, and the two locking marbles are respectively inserted into the upper arc-shaped slide rail and the lower arc-shaped slide rail.

[0034] At the same time, in actual application, the length of the upper arc-shaped slide rail is greater than the length of the lower arc-shaped slide rail.

[0035] Furthermore, in actual use, a limiting marble 5 is fixed to the lower part of the outer wall of the dimming cup, and an annular groove 6 is provided on the inner wall of the face ring. During assembly, the face ring is placed on the outer side of the dimming cup, and the limiting marble is locked in the annular groove to limit the position and rotate. It can be rotated 360 degrees, improving the convenience and effectiveness of use.

[0036] Furthermore, an indicator triangle 7 is fixed on the outer wall of the radiator, and an indicator scale 8 is provided on the outer wall of the dimming cup, and the indicator scale is located above the upper arc-shaped slide rail. During assembly, the angle adjustment can be indicated, making it easier for the operator to intuitively judge the adjustment angle.

[0037] In this embodiment, a protective cable 9 is provided between the top of the radiator and the outer wall of the dimming cup, which can improve the safety of both and prevent the dimming cup from loosening and falling.

[0038] Moreover, for the convenience of installation and use, a mounting spring piece 10 is fixed on the symmetrical side wall of the face ring. The mounting spring piece is used to be installed in the mounting hole position on the ceiling, which improves assembly convenience and effectiveness.

[0039] At the same time, in this embodiment, a U-shaped avoidance groove 11 is provided on the symmetrical edge of the top surface of the dimming cup, which can improve the effectiveness of adjusting the angle.

[0040] The present invention has positive effects: the structure of the present invention is reasonably arranged, and there are two symmetrically arranged slide rail adjustment components between the dimming cup and the radiator, and the slide rail adjustment component includes two locking marbles, a lower arc slide rail and an upper arc slide rail. During assembly, the locking marbles cooperate with the lower arc slide rail and the upper arc slide rail, which can not only realize the installation limit connection, thereby reducing the installation limit structure and improving the convenience and effectiveness of assembly, but also the locking marbles can slide simultaneously in the upper arc slide rail and the lower arc slide rail, which is also convenient for the direction adjustment between the radiator and the dimming cup, and at the same time of direction adjustment, the positions of the two locking marbles in the upper arc slide rail and the lower arc slide rail are different, that is, the locking marbles in the upper arc slide rail can be used as a fulcrum to adjust a certain angle of the locking marbles in the upper arc slide rail, thereby realizing the pitch angle adjustment of the dimming cup within a small range, improving the convenience of adjustment and the applicable range of adjustment, and making the operation more convenient and highly applicable.

[0041] Example 2

[0042] See Figures 3 and 4 As shown, this embodiment is basically the same as embodiment 1, except that: the two locking marbles are fixed on the inner wall of the dimming cup and the two locking marbles are on the same vertical line;

[0043] The upper arc-shaped slide rail and the lower arc-shaped slide rail are located on the outer wall of the radiator, and the upper arc-shaped slide rail is located directly above the lower arc-shaped slide rail;

[0044] The dimming cup is sleeved on the radiator, and the two locking marbles are respectively locked in the upper arc-shaped slide rail and the lower arc-shaped slide rail.

[0045] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0046] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
