Description

Technical Field

[0001] This utility model belongs to the technical field of lighting installation structure, specifically relating to a snap ring structure for a circular metal lampshade. Background Technology

[0002] Existing circular metal lampshades typically use an outer cover and an inner cover to be fixed together by means of threads, screws or welding, while the reflector and the light-transmitting lens are usually installed by gluing.

[0003] However, lampshades secured by threads, screws, or adhesive are cumbersome to install, have low assembly efficiency, and are not conducive to mass production. Furthermore, the light-transmitting lenses and reflectors are prone to loosening, displacement, or even detachment due to external forces, vibrations, or thermal expansion and contraction, affecting the safety of the luminaire. In addition, lampshade assemblies secured by adhesive or welding are difficult to disassemble for later maintenance and replacement of optical components, increasing maintenance costs.

[0004] In view of the above problems, there is an urgent need for a simple, easy-to-assemble, and stable circular hardware lampshade mounting structure to solve the problems of easy loosening of the light-transmitting lens and the refractor during use, complicated installation, and difficult maintenance, so as to improve the stability and service life of the lampshade assembly. Utility Model Content

[0005] In view of the technical problems mentioned in the background art, the purpose of this utility model is to provide a buckle ring structure for a circular metal lampshade to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a snap-fit ​​ring structure for a circular metal lampshade, comprising an outer mounting cover, an inner mounting cover, and a refractive cover. The outer mounting cover has a mounting slot in the middle, and the refractive cover is installed in the mounting slot. A light-transmitting lens is embedded in the front end of the refractive cover. The inner mounting cover is snapped into the mounting slot, and the inner mounting cover presses the light-transmitting lens and the refractive cover together for fixation. It also engages with the outer mounting cover by snapping, so that the light-transmitting lens and the refractive cover are stably clamped between the outer mounting cover and the inner mounting cover.

[0007] Furthermore, both the outer mounting cover and the inner mounting cover are circular ring-shaped structures, and they are coaxially arranged. The inner mounting cover is embedded in the mounting slot along the axial direction.

[0008] Furthermore, the inner side of the mounting slot is evenly provided with several slotted protrusions, and there are fixed positions between the slotted protrusions. The edge of the mounting inner cover is evenly provided with several fixed buckles, and the outer surface of the fixed buckle is provided with a fixed pin. The fixed buckle is embedded in the fixed position in a one-to-one correspondence, and the fixed pin is fastened to the edge of the fixed position to realize the engagement and fixation of the mounting inner cover and the mounting outer cover.

[0009] Furthermore, the front edge of the refractor is provided with an annular positioning protrusion, which is embedded in several of the slotted protrusions to achieve radial positioning of the refractor within the mounting slot.

[0010] Furthermore, the outer surface of the refractor is uniformly provided with several fixed through posts, and the fixed through posts are provided with fixed through holes in the middle.

[0011] Furthermore, the outer mounting cover and the inner mounting cover are integrally formed structures made of metal materials.

[0012] Furthermore, the reflector is a one-piece injection molded structure.

[0013] Furthermore, the light-transmitting lens is an integrated optical sheet made of transparent material, placed at the front end of the refractive cover, and pressed and fixed by the mounting inner cover.

[0014] This utility model has the following advantages: The mounting outer cover, mounting inner cover, refractive cover, and light-transmitting lens are interconnected through a snap-fit ​​structure, positioning protrusions, and fixing pins and holes to form an integrated and stable assembly structure. The mounting inner cover engages with the mounting outer cover through fixing snaps and pins, applying axial clamping force to the refractive cover and light-transmitting lens to achieve reliable positioning and fixation of the optical components; the positioning protrusions and fixing pins of the refractive cover ensure its radial, circumferential, and axial stability. Through the above structural design, the lampshade assembly can be quickly and easily assembled and disassembled. Attached Figure Description

Detailed Implementation

[0020] like Figures 1 to 4As shown, a snap-fit ​​structure for a circular metal lampshade includes an outer mounting cover 10, an inner mounting cover 20, and a refractor 30. The outer mounting cover 10 has a mounting slot 11 in the middle, and the refractor 30 is installed in the mounting slot 11. A light-transmitting lens 40 is embedded at the front end of the refractor 30. The inner mounting cover 20 is snapped into the mounting slot 11. At the same time, the inner mounting cover 20 presses the light-transmitting lens 40 and the refractor 30 to fix them. In use, the inner mounting cover 20 is snapped into the outer mounting cover 10, so that the light-transmitting lens 40 and the refractor 30 are stably clamped between the outer mounting cover 10 and the inner mounting cover 20, thereby achieving reliable positioning and fixation of the light-transmitting lens 40 and the refractor 30.

[0021] In practice, both the outer mounting cover 10 and the inner mounting cover 20 are annular structures, coaxially arranged and mutually cooperating. The inner side of the outer mounting cover 10 has an annular mounting groove 11, and the inner mounting cover 20 can be axially embedded in the mounting groove 11.

[0022] In practical implementation, the inner side of the mounting slot 11 is evenly provided with a plurality of slotted protrusions 111, and a fixing slot 112 is provided between the plurality of slotted protrusions 111; the edge of the mounting inner cover 20 is evenly provided with a plurality of fixing buckles 21, and the outer surface of the plurality of fixing buckles 21 is provided with fixing pins 211. During assembly, the plurality of fixing buckles 21 are embedded one-to-one in the plurality of fixing slots 112, and at the same time, the plurality of fixing pins 211 are respectively fastened to the edge position of the corresponding fixing slot 112 to achieve a snap-fit ​​fixation, thereby forming a stable snap-fit ​​connection structure between the mounting inner cover 20 and the mounting outer cover 10. During use, the inner cover 20 is securely restrained within the mounting slot 11 by the snap-fit ​​structure, and axial pressure is applied to the light-transmitting lens 40 and the refractive cover 30, ensuring that the light-transmitting lens 40 and the refractive cover 30 are stably clamped between the outer cover 10 and the inner cover 20, preventing loosening, displacement, or detachment under vibration or external force. This structural design makes the installation of the inner cover 20 simple and quick, ensures a secure fit, and provides uniform stress distribution across the entire structure, effectively improving the stability and safety of the circular metal lampshade during long-term use.

[0023] In practical implementation, the front edge of the refractor 30 is provided with an annular positioning protrusion 31, which is embedded in several slotted protrusions 111, thereby achieving radial positioning of the refractor 30 within the mounting slot 11. During assembly, the refractor 30 is inserted into the mounting slot 11 axially, and the positioning protrusion 31 and the slotted protrusions 111 cooperate with each other to maintain a stable position of the refractor 30 in both the radial and circumferential directions. At the same time, it ensures that the light-transmitting lens 40 can be correctly placed at the front end of the refractor 30 and pressed and fixed by the mounting inner cover 20, thereby achieving overall stability and rapid assembly of the lampshade assembly.

[0024] In practical implementation, the outer surface of the refractor 30 is uniformly provided with a plurality of fixing posts 32, which are evenly spaced apart on the outer surface of the refractor 30. Each fixing post 32 has a fixing hole 321 in its center. In use, the fixing posts 32 and fixing holes 321 are used to install fasteners, such as screws or bolts, to fix the lamp cover assembly to the lamp body, thereby achieving a stable overall connection of the refractor 30, the light-transmitting lens 40, the inner mounting cover 20, and the outer mounting cover 10.

[0025] In practice, both the outer mounting cover 10 and the inner mounting cover 20 are integrally formed metal structures with high strength and rigidity, which can effectively support the refractive cover 30 and the light-transmitting lens 40, while ensuring the stability of the snap ring structure.

[0026] In practical implementation, the refractive cover 30 is an injection-molded one-piece structure, which has good dimensional accuracy and stability. By adopting an injection-molded one-piece structure, not only is the strength and durability of the refractive cover 30 improved, but the positional accuracy of the optical components is also guaranteed, enhancing the overall reliability and safety of the lamp cover assembly. At the same time, it is convenient for assembly and subsequent disassembly and maintenance.

[0027] In practice, the light-transmitting lens 40 is an integrated optical sheet made of transparent material, which can achieve good light transmittance.

[0028] In summary, the mounting outer cover 10, mounting inner cover 20, refractive cover 30, and light-transmitting lens 40 are interconnected through snap-fit ​​structures, positioning protrusions, and fixing pins and holes to form an integrated and stable assembly structure. The mounting inner cover 20 engages with the mounting outer cover 10 via fixing snaps 21 and fixing pins 211, applying axial clamping force to the refractive cover 30 and light-transmitting lens 40 to achieve reliable positioning and fixation of the optical components. The positioning protrusion 31 and fixing pin 32 of the refractive cover 30 ensure its radial, circumferential, and axial stability. Through the above structural design, the lampshade assembly can be quickly and easily assembled and disassembled.
