[0030] 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.
[0031] Example 1
[0032] See Figures 1 to 5 As shown, an adjustable downlight structure includes a face ring 1, a heat sink 2, and a light source plate 3 and a lamp cup 4 fixed to the bottom surface of the heat sink. Support plates 5 are fixed to the symmetrical edges of the top surface of the face ring. A raised ring 6 is integrally formed on the bottom surface of the heat sink, and tilt adjustment guide grooves 7 are provided on the symmetrical edges of the raised ring. In this embodiment, the heat sink is a conventional structure of the prior art, simply applied, and the height of the face ring can be processed and set as needed. The tilt adjustment guide grooves are mainly used for rotational adjustment.
[0033] Furthermore, in this embodiment, the top of the face ring is located inside the convex ring, and a screw 8 passing through the tilt adjustment guide groove is threadedly connected to the support plate. During use, the heat sink rotates on the face ring and is locked in place by the screw, while the distance between the light source plate and the bottom surface of the face ring changes. Through this structure, the distance between the light source plate and the illumination surface of the face ring can be adjusted, thereby achieving the desired lighting effect and focal length adjustment, meeting the needs of different applications and demonstrating strong applicability.
[0034] In practical applications, at least one vertical groove 9 is provided on the side wall of the convex ring; and a limiting spring piece 10 is provided in the vertical groove, and a V-shaped abutment protrusion 11 is integrally formed on the bottom of the inner side of the limiting spring piece; at the same time, several parallel limiting vertical grooves 12 with V-shaped cross-sections are uniformly provided on the upper part of the outer wall of the face ring; the limiting spring piece has a certain elasticity, so that when rotating, the V-shaped abutment protrusion can not only achieve limiting, but also when the external force is greater than the elastic force of the limiting spring piece, the V-shaped abutment protrusion can also jump in the limiting vertical groove to meet the limiting requirements of different positions, and achieve the initial limiting of the adjustment position in conjunction with the tilt adjustment guide groove.
[0035] During operation, the heat sink rotates within the face ring, and the limiting spring moves between adjacent limiting vertical slots, causing the V-shaped abutment protrusion to engage and limit the position within the limiting vertical slot.
[0036] To ensure the elasticity of the limiting spring, the limiting spring is a stainless steel sheet with a thickness of 0.1-0.2mm; the height of the V-shaped abutment protrusion matches the depth of the limiting vertical groove.
[0037] In this embodiment, an n-shaped clip 13 is fixed to the top of the vertical groove with screws, and the top of the limiting spring is fixed to the recessed area of the n-shaped clip with screws. This structure improves the ease and effectiveness of installing the limiting spring.
[0038] In practical applications, the width of the limiting spring piece matches the width of the vertical groove; and during use, when the radiator is rotated to the highest position, the V-shaped abutment protrusion is located at the upper part of the limiting vertical groove, and when the radiator is rotated to the lowest position, the V-shaped abutment protrusion is located at the lower part of the limiting vertical groove.
[0039] In this embodiment, the outer diameter of the face ring is smaller than the inner diameter of the convex ring, and the inner diameter of the face ring is larger than the outer diameter of the lamp cup. Therefore, raising or lowering the face ring does not affect the use of the lamp cup. The lamp cup and the light source plate are fixed to the bottom surface of the heat sink with screws.
[0040] This utility model has the following positive effects: The structure of this utility model is reasonably designed. Inclined adjustment guide grooves are provided on the symmetrical edges of its convex ring, and a screw threaded through the inclined adjustment guide groove is connected to the support plate. The radiator rotates on the face ring and is locked in place by the screw. Furthermore, the distance between the light source plate and the bottom surface of the face ring changes. During use, rotation and positioning can be achieved simply by rotating the radiator in conjunction with the screw. Adjustment allows for adjustment of the distance between the light source plate and the light-emitting surface of the panel, thus enabling adjustable anti-glare height. This improves the convenience and effectiveness of adjustment and allows for stepless adjustment of the overall structural height, meeting the needs of ceilings of different heights and demonstrating strong applicability.
[0041] Furthermore, it is equipped with a limiting spring with a V-shaped abutment protrusion and a limiting vertical groove, which can achieve limiting during rotation adjustment, improve the stability and reliability of the adjustment position, and improve the adjustment effectiveness in conjunction with the screw, making it highly applicable.
[0042] Example 2
[0043] See Figure 6 As shown, this embodiment is basically the same as embodiment 1, except that: a locking screw 14 is provided on the convex ring; the inner end of the locking screw abuts against the face ring to achieve rotational positioning.
[0044] 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.
[0045] 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.
