Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of down lamp, especially a down lamp cup sleeve clamping installation structure. BACKGROUND

[0002] Down lamp is a light emitting lamp that is embedded in the ceiling, and has a screw cap, which can directly install incandescent lamp or energy-saving lamp. Down lamp belongs to direct light distribution, and all light is projected downward. Different reflectors, lenses, shutters and bulbs can be used to obtain different light effects. Down lamp is a directional lighting lamp, and only its opposite surface can receive light. The light beam angle belongs to spotlight, and the light is relatively concentrated, and the light and dark contrast is strong.

[0003] The down lamp comprises a lampshade part structure at the lower end, and the lampshade part structure comprises a cup sleeve for installing and arranging the whole lamp. However, in the existing down lamp structure, in order to make the cup sleeve and the lamp body more convenient to disassemble and assemble, the stability and reliability of the installation of the cup sleeve and the lamp body are reduced, and the two are prone to falling off, so that the whole lamp is not stable and reliable after installation.

[0004] Therefore, how to design a down lamp cup sleeve clamping installation structure with a simpler and more reasonable structure, which can simultaneously have the advantages of convenient disassembly and assembly and clamping stability and reliability, has become a technical problem to be solved by the technical personnel in the field. CONTENT OF THE UTILITY MODEL

[0006] To achieve the above purpose, the utility model provides a down lamp cup sleeve clamping installation structure, which comprises a cup sleeve sleeved outside an installation cover, and a clamping spring sheet is arranged in pairs on the cup sleeve; a clamping structure is arranged between the cup sleeve and the installation cover; the clamping structure comprises a first clamping structure arranged between the lower end of the installation cover and the cup sleeve; characterized in that the first clamping structure comprises a plurality of installation holes arranged on the outer circumferential surface of the lower end of the installation cover and uniformly distributed in the circumferential direction, a helical spring is arranged in each installation hole, and the outer end of the helical spring is provided with a spring needle arranged horizontally outward, and the spring needle extends to the outside of the installation hole and is correspondingly inserted into a clamping needle hole in the inner circumferential wall of the cup sleeve.

[0007] Thus, in the device structure described above, the helical spring is arranged in the mounting hole in the outer circumferential surface of the lower end of the mounting cover, and the spring needle is arranged at the outer end of the helical spring, extending to the outside of the mounting hole, and can be inserted into the needle clamping hole in the inner circumferential wall of the cup sleeve, thereby achieving the clamping and mounting of the cup sleeve and the mounting cover. Such a structure has the characteristics of convenient assembly and disassembly, and can be more easily assembled in place and more stable and reliable after assembly.

[0008] As an optimization, the outer end of the steel wire for forming the helical spring is bent horizontally outward to form the spring needle.

[0014] As an optimization, the mounting hole is arranged in pairs.

[0015] Thus, the number of mounting holes is more reasonable.

[0016] As an optimization, the clamping spring sheet is riveted to the cup sleeve by the rivet, and the needle clamping hole is formed on the inner end surface of the rivet.

[0017] Thus, the installation of the clamping spring sheet is more convenient, and the structure strength of the needle clamping hole is improved by forming the needle clamping hole in the inner end of the rivet, which better avoids deformation of the needle clamping hole after repeated disassembly and assembly.

[0022] As optimization, a mounting groove is arranged on the inner circumferential surface of the cup sleeve corresponding to the clamping spring piece mounting segment, and the clamping spring piece mounting segment is arranged in the mounting groove.

[0023] In this way, the installation design between the clamping spring piece and the cup sleeve is more reasonable, and the clamping spring piece is more stable.

[0024] As optimization, the clamping structure further includes a second clamping structure arranged between the upper end of the mounting cover and the cup sleeve; the second clamping structure includes a ring-shaped protrusion arranged on the inner circumferential surface of the upper end of the cup sleeve, a clamping groove is arranged on the inner circumferential surface of the protrusion, and a plurality of clamping blocks are uniformly arranged on the outer circumferential surface of the upper end of the mounting cover and protrude outward, and the clamping blocks can be clamped into the clamping groove.

[0025] In this way, by designing the second clamping structure and arranging it at the upper end, the stability of the clamping is further improved.

[0026] Further, the clamping blocks are four and are uniformly distributed in the circumferential direction.

[0027] Further, the upper side of the clamping block is provided with a rounded corner structure.
