Description

Technical Field

[0001] The invention relates to a downlight, and in particular to a mounting structure of the downlight. Background Art

[0002] At present, the installation structure of traditional downlights is relatively simple, including: a mounting barrel (also called a lamp barrel), a mounting hole for inserting the downlight is opened on the bottom wall of the mounting barrel, and a fixed mounting edge is provided near the outer port of the mounting barrel, and the fixed mounting edge usually has multiple circles of mounting holes along the circumference. During installation, the mounting barrel is first fixed on the decorative ceiling, and then the downlight is inserted from the mounting hole of the mounting barrel to the top of the ceiling. As is known to all, the lamp board and power supply of the downlight have a lifespan. When the downlight does not light up and needs to be replaced, the above-mentioned mounting structure makes it more troublesome to disassemble the downlight, and usually a suction cup is required to suck out the downlight. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a downlight installation structure which does not require tools and is very easy to disassemble.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a mounting structure of a downlight, which structure includes: a mounting barrel, in which a mounting cup is sleeved, and the specific structure of the mounting cup includes: a mounting inner barrel, a second annular supporting edge is arranged on the inner wall of the inner end of the mounting inner barrel, a guide inner barrel extending outward is arranged at the inner edge of the second annular supporting edge, and an annular positioning edge is arranged outward at the outer end edge of the mounting inner barrel; the specific structure of the mounting barrel includes: a mounting outer barrel, a guide outer barrel extending into the mounting outer barrel and cooperating with the guide inner barrel is arranged at the bottom of the inner end of the mounting outer barrel, an annular limiting edge cooperating with the annular positioning edge is arranged outward at the outer end edge of the mounting inner barrel, and a fixed mounting edge is arranged on the outer wall of the mounting inner barrel; an mounting cup locking mechanism for locking the mounting cup on the mounting barrel is arranged between the guide inner barrel and the guide outer barrel.

[0005] As a preferred embodiment, in the installation structure of a downlight, the guide outer tube is arranged at the bottom of the inner end of the installation outer tube through a first annular supporting edge, that is, the bottom of the inner end of the installation outer tube is provided with a first annular supporting edge, and the outer end of the guide outer tube is arranged at the inner edge of the first annular supporting edge.

[0006] As a preferred solution, in the installation structure of the downlight, a conical connecting tube is provided between the first annular supporting edge and the guide outer tube.

[0007] As a preferred embodiment, in the installation structure of a downlight, a placement ring extending toward the annular positioning edge is provided at the outer edge of the annular limiting edge, and a positioning ring matching the annular limiting edge is provided at the outer edge of the annular positioning edge.

[0008] As a preferred solution, in the installation structure of a downlight, the installation cup locking mechanism includes: at least two locking protrusions which are circumferentially arranged on the guide inner cylinder and protrude outward.

[0009] As a preferred solution, in the installation structure of the downlight, at least two locking support parts are evenly arranged on the guide inner tube along the circumferential direction, and the locking protrusions are arranged on the corresponding locking support parts.

[0010] As a preferred solution, in the installation structure of a downlight, the locking support part is specifically arranged as follows: two separation grooves are downwardly provided at the top of the guide inner tube, and the guide inner tube forms a corresponding locking support part between the two separation grooves.

[0011] The beneficial effect of the present invention is that, by adding a mounting cup, the mounting cup is first installed in the mounting barrel, and then the downlight is installed in the mounting cup. When disassembling, the finger surfaces of multiple fingers are first contacted with the inner wall of the mounting inner barrel, and the mounting cup is pulled outward for a distance by friction. At this time, the positioning ring at the outer edge of the mounting cup can be grasped by hand, and the mounting cup together with the downlight can be pulled out of the mounting outer barrel. The entire disassembly process does not require any tools and is very easy and convenient. In addition, the mounting cup is also equivalent to a reflective cup, which increases the light effect, which can be said to kill two birds with one stone. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The following is a detailed description of the specific implementation scheme of the installation structure of a downlight according to the present invention in conjunction with the accompanying drawings:

[0018] like Figures 1 to 4 As shown, the installation structure of a downlight described in the present invention comprises an installation barrel 2, in which an installation cup 3 is sleeved, and the specific structure of the installation cup 3 comprises: an installation inner barrel 31, an inner end edge of the installation inner barrel 31 is provided with a second annular support edge 32 inwardly, an inner side edge of the second annular support edge 32 is provided with a guide inner barrel 33 extending outwardly, and three locking support portions 331 are evenly arranged along the circumferential direction of the guide inner barrel 33, and the specific arrangement method of the locking support portion 331 is as follows: the guide inner barrel 31 is provided with a second annular support edge 32 inwardly, and the inner side edge of the second annular support edge 32 is provided with a guide inner barrel 33 extending outwardly. The top of the inner cylinder 33 is downwardly provided with two mutually matching dividing grooves 330, and the guiding inner cylinder 33 forms a corresponding locking support portion 331 between the two dividing grooves 330; the locking support portion 331 is provided with a locking protrusion 332 protruding outward, so that the locking support portion 331 and the locking protrusion 332 on the locking support portion 331 form a mounting cup locking mechanism for locking the mounting cup 3 on the mounting barrel 2, and the outer end of the mounting inner cylinder 31 is provided with an annular positioning edge 311 outwardly along the outer edge of the mounting inner cylinder 31, The outer edge of the shaped positioning edge 311 is provided with an annular positioning ring 312 toward the installation barrel 2; the specific structure of the installation barrel 2 includes: an installation outer cylinder 21, a first annular supporting edge 22 is provided inwardly at the bottom edge of the installation outer cylinder 21, and a conical connecting cylinder 23 extending into the installation outer cylinder 21 and a guide outer cylinder 24 matching the guide inner cylinder 33 are sequentially provided inwardly at the edge of the first annular supporting edge 22, that is, a conical connecting cylinder 23 is provided at the edge of the first annular supporting edge 22, and a conical connecting cylinder 23 is provided. A guide outer cylinder 24 is provided on the connecting cylinder 23; an annular limiting edge 211 matching the annular positioning edge 311 is provided outwardly at the outer end edge of the mounting inner cylinder 21, and a placement ring 212 extending toward one side of the annular positioning edge 311 is provided at the outer edge of the annular limiting edge 211; an annular fixed mounting edge 20 is provided on the outer wall of the mounting inner cylinder 21 near the annular limiting edge 211, and two circles of a plurality of mounting fixing holes 201 are provided circumferentially on the annular fixed mounting edge 20.
