Description

Technical Field

[0001] This utility model belongs to the technical field of lighting devices, specifically relating to a front ring mounting structure and a lamp. Background Technology

[0002] Currently, most recessed or ceiling-mounted LED spotlights on the market use a front ring (or mask) to fix the optical components inside the lamp body, ensuring that the optical components accurately receive and emit light when the spotlight is working, thereby achieving the desired light emission effect.

[0003] In existing methods of fixing the front ring to the lamp body, most employ either threaded locking or traditional snap-fit ​​methods. Threaded locking generally refers to two types of threaded connections: one involves a threaded structure at the contact point between the front ring and the lamp body, where the front ring is rotated during installation to screw it into the predetermined position on the lamp body, thus securing it. The other involves a threaded hole on the front ring or a threaded mounting post structure on the lamp body, where threaded fasteners are used to lock the front ring and lamp body in place. Clearly, threaded locking methods have low assembly efficiency and are prone to thread stripping after repeated disassembly and reassembly. Traditional snap-fit ​​methods, on the other hand, are limited by material deformation, resulting in a small locking amount. Under conditions of thermal expansion and contraction, these snap-fit ​​structures are prone to loosening and falling off, posing a safety risk to personnel below the lamp fixture. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a front ring mounting structure. It achieves a first-level fixation by connecting the front ring to the slot via a locking block, and then inserts the end of a locking component through a through hole for double locking. This ensures a reliable connection between the front ring and the lamp body, preventing the risk of it falling off.

[0005] The technical effect to be achieved by this utility model is realized through the following technical solution:

[0006] Firstly, this utility model provides a front ring mounting structure, including a lamp body, a front ring, and a locking component.

[0007] The lamp body includes a base plate and a side plate disposed on the base plate. The base plate and the side plate surround to form a receiving cavity. The receiving cavity has a light outlet. The side plate has a locking block and a socket on its inner side wall.

[0008] The front ring includes a first ring body and a second ring body disposed inside the first ring body, wherein the first ring body is provided with a slot and a through hole;

[0009] The card block is connected to the card slot, the locking member is locked to the insertion hole, and the end of the locking member passes through the through hole. The front ring is located at the light outlet.

[0010] In some implementations, the via is elliptical, quasi-elliptical, or racetrack-shaped, and the end of the locking member does not abut against the first ring body.

[0011] In some implementations, two vias are provided, which are radially opened on the first ring body. A first protrusion is provided on the top edge of the first ring body, and the first protrusion is located above the vias.

[0012] In some implementations, the plane containing the top edge of the first ring body is used as the base plane, and the projection of the first protrusion on the base plane covers the projection of the via on the base plane.

[0013] In some implementations, the top edge of the first ring body is further provided with a second protrusion, which is located above the card slot, and the projection of the second protrusion on the base surface covers the projection of the card slot on the base surface.

[0014] In some implementations, the top edge of the first ring body is also provided with a third protrusion, and the third protrusion is provided with a positioning groove;

[0015] The side plate is also provided with a positioning post on its inner side wall. The positioning post is inserted into the positioning groove and is used to guide the front ring to be installed in the lamp body.

[0016] In some implementations, the card block includes a guide portion and a fixing portion, the guide portion being obliquely disposed on the inner sidewall of the side plate; the first ring body is guided to deform via the guide portion, and the fixing portion abuts against the first ring body.

[0017] In some implementations, the slot is disposed adjacent to the through hole, and the slot has a rectangular structure.

[0018] Secondly, this utility model provides a lamp, including a light-emitting component, a lens and a cover, as well as the aforementioned front ring mounting structure;

[0019] The cover is fitted around the periphery of the lamp body. The cover has a through hole. The locking member passes through the through hole and is fixed in the insertion hole. At the same time, the end of the locking member extends into the through hole.

[0020] The light-emitting component and the lens are mounted in the receiving cavity.

[0021] In some implementations, the front ring further includes positioning ribs that extend from the outside of the second ring body toward the first ring body; the positioning ribs form a limiting ring around the first ring body, and the light-emitting end of the lens is located in the limiting ring.

[0022] In summary, this utility model has at least the following advantages:

[0023] 1. The front ring mounting structure provided by this utility model first connects the locking block to the slot, making the front ring and the lamp body a single fixed connection, and then inserts the end of the locking piece into the through hole to complete the double locking. Even if there is a risk of the locking block and the slot separating due to environmental changes or other factors, the front ring and the lamp body can maintain a reliable connection to avoid the risk of falling off.

[0024] 2. The front ring mounting structure provided by this utility model achieves double locking by facilitating the connection between the locking block and the slot, and by allowing the locking component to be inserted only at its end into the through hole. While ensuring a stable connection, the assembly and disassembly efficiency is higher than existing threaded connection methods. Both the slot and the through hole are located on the first ring body, simplifying the overall structure of the front ring and reducing manufacturing difficulty.

[0025] 3. The lamp provided by this utility model, after adopting the above-mentioned front ring mounting structure, only requires the lamp body, front ring and locking parts to complete the stable and quick connection of the front ring. The number of parts is small and the lamp has a longer service life. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0047] Example 1:

[0048] Please see Figures 1-4 This embodiment provides a front ring mounting structure 100, which is applied to recessed or ceiling-mounted lighting fixtures. The front ring mounting structure 100 includes a lamp body 1, a front ring 2, and a locking member 3. Specifically, the lamp body 1 includes a base plate 11 and a side plate 12 disposed on the base plate 11. The base plate 11 and the side plate 12 surround to form a receiving cavity 13, which has a light outlet 131. The side plate 12 has a locking block 121 and a insertion hole 122 on its inner sidewall. The front ring 2 includes a first ring body 21 and a second ring body 22 disposed inside the first ring body 21. The first ring body 21 has a locking groove 211 and a through hole 212.

[0049] Furthermore, the card block 121 is snapped into the card slot 211, the locking component 3 is locked into the insertion hole 122, and the end of the locking component 3 is inserted into the through hole 212, and the front ring 2 is set at the light outlet 131.

[0050] During installation, the locking element 3 is pre-installed in the socket 122. Then, the locking block 121 is aligned with the slot 211, and the front ring 2 enters the lamp body 1 from the light outlet 131. The first ring 21 is aligned with the inner wall of the lamp body 1 until the locking block 121 and the slot 211 are engaged, completing the first layer of fixation. Afterward, the position of the front ring 2 and the lamp body 1 no longer changes. At this time, the socket 122 and the through hole 212 are basically aligned. The locking element 3, which has been installed in the socket 122, is then further tightened, so that the end of the locking element 3 is inserted into the through hole 212, completing the second layer of locking fixation.

[0051] In actual use, due to the different materials, shapes, and structures of the lamp body 1 and the front ring 2, they are affected by temperature differently. For example, the lamp body 1 often uses metal parts, relatively rigid plastic parts, or metal-embedded plastic structural parts to ensure the overall strength of the lamp body 1. At the same time, the presence of metal materials in the lamp body 1 also improves the heat dissipation of the light-emitting component and reduces the operating temperature of the light-emitting component during operation. The front ring 2, on the other hand, is usually a one-piece injection molded part, and its temperature effect is obviously different from that of the lamp body 1. In areas with large temperature variations, or during periods of large temperature changes before and after use, or when long-term temperature fluctuations cause aging and deformation of the lamp body 1 and the front ring 2, even if there is a risk of detachment due to the snap-fit ​​fixing method of the locking block 121 and the locking slot 211, the locking element 3 can ensure a reliable connection between the front ring 2 and the lamp body 1. Therefore, the front ring mounting structure 100 described in this embodiment has a stable and reliable connection.

[0052] The snap-fit ​​structure between the locking block 121 and the slot 211 is simple and efficient, while the locking piece 3 only needs to be inserted into the through hole 212 at its end to achieve double locking. While ensuring a stable connection, the assembly and disassembly efficiency is higher than that of the threaded fixing method.

[0053] In this embodiment, the locking member 3 uses a common threaded fastener. The locking member 3 is locked into the insertion hole 122 via a threaded connection, and then inserted through the through hole 212 at its end to complete the double locking. In other embodiments, the locking member 3 can use a spring-operated structure, that is, a combination of a push button, a spring, and an intermittent latching device. When a second locking of the front ring 2 is required, the locking member 3 is pressed from the outside, causing its end to penetrate and stop in the through hole 212. When the front ring 2 needs to be disassembled, the locking member 3 is pressed again from the outside, causing its end to first enter the through hole 212 and then withdraw, completing the disengagement of the locking member 3.

[0054] To improve installation efficiency and reduce the alignment requirements between the front ring 2 and the lamp body 1 during installation, in this embodiment, the through hole 212 is elliptical, quasi-elliptical, or racetrack-shaped, so that the slot 211 and the locking block 121 do not need to be precisely snapped together, and the end of the locking member 3 can also be inserted into the through hole 212. Furthermore, to further improve the service life of the locking member 3 and the front ring 2 and reduce wear, the end of the locking member 3 does not abut against the first ring body 21; specifically, the end of the locking member 3 does not abut against the inner wall of the through hole 212.

[0055] In some embodiments, two through holes 212 are provided, which are radially formed on the first ring body 21. A first protrusion 213 is provided on the top edge of the first ring body 21, and the first protrusion 213 is located above the through holes 212. Providing two through holes 212 allows for a double-locking effect between the front ring 2 and the lamp body 1 with a minimum number of locking pieces 3, improving the installation efficiency of the front ring 2. The radial formation of the two through holes 212 on the first ring body 21 facilitates the forming of the through holes 212 on the front ring 2, reducing the difficulty of mold material output and lowering mold production costs. The first protrusion 213 strengthens the first ring body 21 above the through holes 212, enhancing the effectiveness of the double-locking. Of course, in other embodiments, three or more through holes 212 can also be provided; the principle is basically the same, and will not be elaborated here.

[0056] In a further embodiment, the plane containing the top edge of the first ring 21 is used as the base plane, and the projection of the first protrusion 213 on the base plane covers the projection of the through hole 212 on the base plane. For example... Figure 4 As shown, the reinforcement effect of the first protrusion 213 on the through hole 212 is effectively guaranteed, and the stress concentration problem of the first ring body 21 near the through hole 212 is avoided during the production process, thus ensuring the shape of the through hole 212.

[0057] Similarly, the top edge of the first ring body 21 is also provided with a second protrusion 215, which is located above the slot 211. The projection of the second protrusion 215 on the base surface covers the projection of the slot 211 on the base surface. After adding the second protrusion 215, the strength of the first ring body 21 at the slot 211 position is effectively improved. The snap-fit ​​connection between the snap-fit ​​block 121 and the slot 211 is more stable, and the service life of the snap-fit ​​block 121 and the slot 211 is also improved.

[0058] However, it should be noted that in the direction from the first ring 21 to the second ring 22, the thickness of the first protrusion 213 can be greater than the thickness of the first ring 21 to obtain better structural strength. The thickness of the second protrusion 215 should be as similar as possible to or slightly smaller than the thickness of the first ring 21. When the locking block 121 and the locking groove 211 are engaged, the top pressure of the second protrusion 215 on the locking block 121 can be reduced, thereby reducing wear on the locking block 121.

[0059] In some embodiments, the top edge of the first ring 21 is further provided with a third protrusion 216, and the third protrusion 216 has a positioning groove 2161. Furthermore, the side plate 12 is provided with a positioning post 123 on its inner sidewall, which is inserted into the positioning groove 2161 to guide the front ring 2 into the lamp body 1. The cooperation between the positioning groove 2161 and the positioning post 123 allows the installation position of the front ring 2 and the lamp body 1 to be aligned in advance, enabling blind operation during installation and preventing mistaken installation. It eliminates the need for careful alignment of the locking block 121 and the locking groove 211, further improving installation efficiency.

[0060] In this embodiment, please continue to refer to... Figures 1-4 The locking block 121 includes a guide portion 1211 and a fixing portion 1212. The guide portion 1211 is obliquely disposed on the inner sidewall of the side plate 12. The first ring body 21 is guided to deform via the guide portion 1211, and the fixing portion 1212 abuts against the first ring body 21. Under the guidance of the guide portion 1211, the first ring body 21 gradually deforms until the locking block 121 is fully inserted into the locking groove 211. After insertion, the fixing portion 1212 abuts against the first ring body 21. At this time, the guide portion 1211 structurally strengthens the fixing portion 1212 and also reduces the deformation of the fixing portion 1212 due to temperature.

[0061] Furthermore, to achieve a better demolding effect, in this embodiment, the slot 211 is adjacent to the through hole 212, and the slot 211 and the through hole 212 penetrate the first ring body 21 in the same direction, so that the slot 211 and the through hole 212 can be formed in one step. The slot 211 has a rectangular structure, which facilitates the shape setting of the card block 121, reduces the production difficulty, and at the same time ensures the limiting effect of the card block 121 and the slot 211, reducing the limiting deviation between the front ring 2 and the lamp body 1.

[0062] In summary, the front ring mounting structure provided in this embodiment first connects the locking block to the slot, thus securing the front ring to the lamp body with a single layer of fixation. Then, the end of the locking pin is inserted into the through hole to complete a double locking. Even if the locking block and slot are at risk of detachment due to environmental changes or other factors, the front ring and lamp body can maintain a reliable connection, avoiding the risk of falling off.

[0063] Secondly, the connection between the locking block and the slot is convenient, and the locking component only needs to be inserted into the through hole at its end to achieve double locking. While ensuring a stable connection, the assembly and disassembly efficiency is higher than that of existing threaded connections. Both the slot and the through hole are located on the first ring body, making the overall structure of the front ring simpler and reducing production difficulty.

[0064] Example 2:

[0065] Please Figures 1-4 Based on the above, refer to Figure 5 This embodiment provides a lamp 200, including a light-emitting component 5, a lens 6, and a faceplate 7, as well as the front ring mounting structure 100 described in Embodiment 1.

[0066] Specifically, the cover 7, as a component connecting the lamp body 1 to the external base, is fitted around the outer periphery of the lamp body 1. The cover 7 has a through hole 71, through which the locking member 3 passes and is fixed in the insertion hole 122. At the same time, the end of the locking member 3 extends into the through hole 212. Both the front ring 2 and the cover 7 are fixed to the lamp body 1 by the same locking member 3, reducing the number of parts in the lamp 200 and thus improving the efficiency of lamp 200 installation.

[0067] Furthermore, the light-emitting component 5 and the lens 6 are mounted in the receiving cavity 13. The light-emitting component 5 is mounted on the substrate 11 by fasteners or other fixing methods. The lens 6 has a light-incident end 61 and a light-exit end 62. The light-incident end 61 abuts against the light-emitting component 5, and the light-exit end 62 faces the light-exit port 131. The lens 6 is fixed and limited between the front ring 2 and the light-emitting component 5.

[0068] By adopting the front ring mounting structure 100, while ensuring a stable and convenient connection of the front ring 2, the installation and removal of the lamp 200 results in less wear and tear and a longer service life compared to the threaded connection method.

[0069] In this embodiment, at least three sets of locking blocks 121 and locking slots 211 are provided, and are respectively arranged along the circumferential direction of the inner side wall of the side plate 12 and the circumferential direction of the first ring body 21. Three or more sets of locking blocks 121 and locking slots 211 can effectively avoid loosening problems caused by large installation tolerances or different cores between the front ring 2 and the lamp body 1, thereby ensuring the effectiveness of the first layer of fixation.

[0070] In summary, the lamp provided in this embodiment, after adopting the front ring mounting structure described in Embodiment 1, only requires the lamp body, the front ring, and the locking component to complete the stable and quick connection of the front ring. The number of parts is small, and the lamp has a longer service life.

[0071] Example 3:

[0072] Please Figures 1-5 Based on the above, refer to Figures 6-7 This embodiment provides a lamp 200, which is a structural adjustment based on embodiment 2. Specifically, the front ring 2 further includes a positioning rib 4, which extends from the outside of the second ring body 22 toward the first ring body 21. The positioning rib 4 surrounds to form a limiting ring 41, and the light-emitting end 62 of the lens 6 is located in the limiting ring 41.

[0073] The positioning ribs 4, located between the first ring 21 and the second ring 22, strengthen the overall strength of the front ring 2 and reduce the overall deformation of the first ring 21 and the second ring 22 under the influence of ambient temperature or external force. This ensures the effective and stable double-locking connection between the front ring 2 and the lamp body 1. A mounting structure that cooperates with the limiting ring 41 is generally provided on the outer side of the light-emitting end 62 of the lens 6. The limiting ring 41 formed by the positioning ribs 4 can accurately fix the lens 6 with the mounting structure to the front ring 2 in advance. Through the cooperation between the front ring 2 and the lamp body 1, the position of the lens 6 and the light-emitting component 5 is effectively guaranteed, ultimately achieving the predetermined light emission effect.

[0074] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
