Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a connection structure for a downlight. Background Technology

[0002] Downlights are a common type of illumination device, installed in areas requiring lighting. To meet diverse needs, those skilled in the art are continuously developing new downlight products. Utility Model Content

[0003] This utility model provides a connection structure for downlights that is easy to install, and offers a new structural approach for downlights.

[0004] The above technical problems are solved by the following technical solution: a connection structure for a downlight, characterized in that it includes a downlight body and a hanging plate with a downlight mounting hole. The downlight body is detachably installed in the downlight mounting hole in a downward-facing manner. The downlight body has an annular decorative panel that covers the downlight mounting hole. The rear surface of the annular decorative panel has several hanging blocks with hanging steps distributed circumferentially along the annular decorative panel. The hanging plate has several hanging holes distributed circumferentially along the downlight mounting hole. Each hanging hole has a widened section that allows the hanging blocks to pass through. Each hanging block is correspondingly inserted into the hanging hole. The hanging block is hooked onto the upper surface of the hanging plate and suspended in the hanging hole by the hanging steps. In use, the downlight body is passed from bottom to top through the downlight mounting hole with the hanging blocks aligned with the widened sections until the hanging steps are above the annular decorative panel. Then, the downlight body is rotated until the hanging blocks are in the hanging holes, causing the downlight body to move downward and be suspended on the upper surface of the annular decorative panel by the hanging steps, thus achieving the connection between the downlight body and the annular decorative panel.

[0005] Preferably, the suspension block includes a base section integrally formed with the annular decorative panel and a tail section detachably connected to the base section. The upper end face of the base section has a threaded hole, and the lower end of the tail section has a threaded head. The threaded head is threaded into the threaded hole of the base section, forming the suspension step between the tail section and the base section. Leveling of the downlight body can be achieved by rotating the tail section to the depth it is screwed into the base section.

[0006] Preferably, the circumferential surface of the final section is provided with several drag-increasing vertical protrusions distributed along the circumference of the final section. This prevents slippage when the final section is rotated.

[0007] Preferably, the system also includes a supporting sleeve, in which the downlight body is rotatably connected. The upper surface of the annular decorative panel has a limiting sleeve, and the annular decorative panel extends into the limiting sleeve to form a hanging flange. The outer surface of the supporting sleeve has an anti-rotation block, and the upper surface of the hanging flange has an anti-rotation notch. The anti-rotation block passes through the anti-rotation notch and is suspended on the hanging flange. This achieves a rotatable installation between the downlight body and the annular decorative panel.

[0008] Preferably, the upper surface of the suspension flange is provided with a plurality of reinforcing strips distributed circumferentially along the suspension flange. The reinforcing strips extend circumferentially along the suspension flange, and the anti-rotation notch is formed between adjacent reinforcing strips. The reinforcing strips are connected together with the limiting sleeve, and the limiting sleeve, the annular decorative panel and the reinforcing strips are integrally formed together. The structure has good strength.

[0009] Preferably, the upper surface of the reinforcing strip is provided with a plurality of reinforcing blocks, the reinforcing blocks being connected together with the limiting sleeve, and the reinforcing blocks, reinforcing strip, and limiting sleeve being integrally formed together. This results in good structural strength.

[0010] Preferably, between the two reinforcing strip ends located at both ends of the anti-rotation notch, one reinforcing strip end is flush with the same reinforcing block, and the other reinforcing strip end has a guide slope facing towards the anti-rotation notch defect. This facilitates the assembly of the support sleeve into the limiting sleeve to the set position.

[0011] This utility model has the following advantages: it is convenient to install downlights, and the downlights can rotate as if they were panels. Attached Figure Description
