Technical Field
[0001] This utility model relates to the field of downlight technology, and in particular to a downlight lampshade adjustment and limiting structure. Background Technology
[0002] A downlight is a type of recessed lighting fixture that shines downwards into the ceiling. It has a screw-in lamp holder that can directly mount incandescent or energy-saving bulbs. Downlights are direct light sources, projecting all light downwards. Different reflectors, lenses, blinds, and bulbs can be used to achieve various lighting effects. They are directional lighting fixtures, meaning only the area opposite the light source receives light. The beam angle is focused, resulting in concentrated light and strong contrast between light and shadow.
[0003] Downlight housings typically consist of an upper housing and a lower lampshade. The lampshade usually has a light guide. Existing lampshade structures either have the drawback that the lampshade cannot be adjusted, thus failing to meet lighting requirements, or the light guide cannot be properly positioned after adjustment, thus failing to meet usage requirements.
[0004] Therefore, how to design a downlight cover adjustment and limiting structure that is simpler in structure, makes it easier to adjust the light guide cover according to lighting needs, and better limits the position of the light guide cover has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to design a downlight cover adjustment and limiting structure with a simpler structural design, which can more conveniently adjust the light guide cover according to lighting needs and better limit the position of the light guide cover.
[0006] To achieve the above objectives, this utility model provides a downlight lampshade adjustment and limiting structure, including a lampshade body, which includes an upper connecting cover and a lower mounting cover; the connecting cover includes a lower connecting cylinder with an overall rectangular cylindrical structure design, and the mounting cover includes an upper mounting cylinder sleeved outside the connecting cylinder, and a light guide cover with an overall conical cylindrical structure design is installed at the lower end inside the mounting cover; the characteristic feature is that the mounting cylinder is vertically rotatable and sleeved on the connecting cylinder through a hinge structure; a plurality of vertically distributed limiting teeth are provided on the inner side wall of the mounting cylinder, and a limiting protrusion is provided on the lower outer side wall of the connecting cylinder, which can cooperate with the limiting teeth to limit the rotation angle between the connecting cylinder and the mounting cylinder.
[0007] In this device structure, the connecting cover and the mounting cover are hinged together, allowing for angle adjustment. This, in turn, allows for adjustment of the angle between the light guide cover installed within the mounting cover and the connecting cover, enabling the overall lighting angle of the lamp to be adjusted as needed. Secondly, by providing limiting teeth on the inner wall of the mounting cylinder and limiting protrusions on the outer wall of the lower end of the connecting cylinder, with the limiting protrusions engaging with the limiting teeth, the rotation angle between the connecting cylinder and the mounting cylinder is limited. This makes adjustment easier and more complete, and the limiting structure more stable and reliable.
[0008] As an optimization, a vertically arranged guide groove is provided on the inner side wall of the mounting cylinder, and the limiting teeth are provided on the bottom surface of the guide groove.
[0009] In this way, by setting a guide groove and setting a limiting tooth inside the guide groove, the structural design becomes simpler and more reasonable.
[0010] As an optimization, the width of the limiting protrusion is set to match the width of the guide groove.
[0011] In this way, the limiting protrusion and the guide groove have a guiding effect, allowing the limiting teeth and the limiting protrusion to cooperate better.
[0012] Furthermore, on the outer peripheral wall of the connecting cylinder, on both sides corresponding to the limiting protrusion, there are deformation cuts that penetrate the wall thickness direction of the connecting cylinder, and the lower end of the deformation cut penetrates the lower end face of the connecting cylinder.
[0013] This allows the limiting protrusion to better deform inward, making it easier to adjust the angle.
[0014] As an optimization, the hinge structure includes hinge holes on both sides of the lower end of the mounting cylinder, hinge screws are provided in the hinge holes, and the inner ends of the hinge screws are connected to the hinge connection holes on both sides of the connecting cylinder.
[0015] In this way, the hinge structure design is simpler and more reasonable, and it is easier to assemble and disassemble.
[0016] As an optimization, each of the two side walls at the lower end of the connecting cylinder is provided with an outwardly protruding hinge boss, and the hinge connection hole is provided on the hinge boss.
[0017] In this way, by setting a hinge boss, it is easier to process the hinge hole.
[0018] As an optimization, a connecting cover is fixed inside the connecting cover, and the lower end of the connecting cover is connected to the upper end of the light guide cover.
[0019] In this way, by setting up a connecting cover, the upper and lower parts can be better connected, and the light guiding effect can be improved.
[0020] As an optimization, the connecting cover includes an upper section with an overall frustum-shaped structure and a lower section with a cylindrical structure.
[0021] In this way, the structural design of the connecting cover is simpler and more reasonable.
[0022] As an optimization, the lower end of the lower section of the connecting cover is cut off on one side, and the position on the lower end surface of the lower section of the connecting cover opposite to the cut-off part is inclined.
[0023] This design makes the connecting cover more reasonable and allows it to better cooperate with the light guide cover at the bottom.
[0024] As an optimization, the connecting cover also includes an upper docking cylinder for connecting to the lamp housing; and the docking cylinder, connecting cylinder and connecting cover are integrally formed.
[0025] This makes processing and manufacturing more convenient.
[0026] As an optimization, the upper side of the mounting cylinder is cut off, and the position on the upper surface of the mounting cylinder opposite to the cut-off part is inclined.
[0027] This design makes the upper part of the mounting cylinder more reasonable, thus better avoiding interference when adjusting the angle.
[0028] In summary, the above-mentioned device structure has the advantages of simpler structural design, easier adjustment of the light guide cover according to lighting requirements, and better limitation of the light guide cover. Attached Figure Description

This, in turn, allows for adjustment of the angle between the light guide cover installed within the mounting cover and the connecting cover, enabling the overall lighting angle of the lamp to be adjusted as needed. Secondly, by providing limiting teeth on the inner wall of the mounting cylinder and limiting protrusions on the outer wall of the lower end of the connecting cylinder, with the limiting protrusions engaging with the limiting teeth, the rotation angle between the connecting cylinder and the mounting cylinder is limited.

[0044] In this way, the limiting protrusion and the guide groove have a guiding effect, allowing the limiting teeth and the limiting protrusion to cooperate better.
[0045] Furthermore, on the outer peripheral wall of the connecting cylinder, on both sides corresponding to the limiting protrusion, there are deformation cuts that penetrate the wall thickness direction of the connecting cylinder, and the lower end of the deformation cut penetrates the lower end face of the connecting cylinder.

[0049] In this specific embodiment, each of the two side walls at the lower end of the connecting cylinder is provided with an outwardly protruding hinge boss 12, and the hinge connection hole is provided on the hinge boss.

[0051] In this specific embodiment, a connecting cover 13 is fixedly connected inside the connecting cover, and the lower end of the connecting cover is connected to the upper end of the light guide cover.
[0052] In this way, by setting up a connecting cover, the upper and lower parts can be better connected, and the light guiding effect can be improved.
[0053] In this specific embodiment, the connecting cover includes an upper section 14 with an overall frustum-shaped structure at the upper end, and a lower section 15 with a cylindrical structure at the lower end.
[0054] In this way, the structural design of the connecting cover is simpler and more reasonable.
[0055] In this specific embodiment, the lower end of the lower section of the connecting cover is cut off entirely, and the position on the lower end surface of the lower section of the connecting cover opposite to the cut-off part is inclined.

[0057] In this specific embodiment, the connecting cover also includes an upper docking cylinder 16 for connecting with the lamp housing; and the docking cylinder, connecting cylinder and connecting cover are integrally formed.
[0058] This makes processing and manufacturing more convenient.
[0059] In this specific embodiment, the upper end of the mounting cylinder is cut off entirely, and the position on the upper surface of the mounting cylinder opposite to the cut-off part is inclined.
[0060] This design makes the upper part of the mounting cylinder more reasonable, thus better avoiding interference when adjusting the angle.
[0061] In summary, the above-mentioned device structure has the advantages of simpler structural design, easier adjustment of the light guide cover according to lighting requirements, and better limitation of the light guide cover.
