Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a connecting component and an embedded lighting fixture equipped with the connecting component. Background Technology

[0002] Recessed lighting fixtures (such as downlights and spotlights) are one of the mainstream lighting fixtures in the field of indoor lighting. They are installed by being embedded in the pre-set mounting holes in the ceiling, which has the advantage of being easy to install and remove.

[0003] like Figure 1 As shown, an existing type of recessed lighting fixture 9 includes a lamp body 91, a light-emitting module 92, a reflector 93, a face ring 94, and spring clips 95. The lamp body 91 has an internal receiving cavity 911, within which the light-emitting module 92 and the reflector 93 are housed. The face ring 94 is mounted on the lamp body 91 and covers the open end of the receiving cavity 911. Two spring clips 95 are symmetrically arranged on opposite sides of the lamp body 91, and the spring clips 95 engage with the eaves 941 of the face ring 94 to form a clamping position. When the recessed lighting fixture 9 is installed in a mounting hole in the ceiling, the engagement of the spring clips 95 with the eaves 941 of the face ring 94 clamps and fixes the recessed lighting fixture 9 to the ceiling. However, the spring clip 95 mounting structure of this recessed lighting fixture 9 has the following defects: First, the spring 95 is additionally fixed to the lamp body 91 by fasteners 96 (such as bolts or rivets), which makes the assembly process cumbersome, reduces production assembly efficiency, and increases the number of parts required for assembly, thus increasing production costs.

[0004] Second, in order to reduce the number of parts required for assembly, a limiting structure 912 is required on the lamp body 91 to cooperate with the spring piece 95 to limit the rotation of the spring piece 95 relative to the lamp body 91 around the axis of the bolt or rivet, so that the same spring piece 95 does not need to be fixed by two fasteners 96.

[0005] Third, the fixing method of the spring 95 and the lamp body 91 has maintenance defects. For example, if bolts are used to connect the spring 95 and the lamp body 91, the bolts need to be tightened and loosened repeatedly when replacing the spring 95. This not only makes the operation complicated but also requires special tools. In addition, repeated tightening can easily cause stripping of the connecting holes on the lamp body 91, which significantly reduces the connection strength between the spring 95 and the lamp body 91 and its long-term reliability. If rivets are used to connect the spring 95 and the lamp body 91, the spring 95 cannot be replaced, reducing the maintainability of the recessed lamp 9. Utility Model Content

[0006] To address the aforementioned problems, the primary objective of this invention is to provide a connection component that reduces costs, is easy to assemble, and is highly maintainable.

[0007] The second objective of this invention is to provide an embedded lamp with the aforementioned connecting components.

[0008] To achieve the first objective of this utility model, a connecting assembly is provided, including a face ring and a spring piece. The face ring includes a bottom edge and a ring wall, with the bottom edge surrounding the bottom outer periphery of the ring wall. The ring wall includes a ring portion and a plate portion. The plate portion has a first slot, and at the top of the plate portion, the inner side of the plate portion forms a first slot with the ring portion. The spring piece includes a connecting plate portion and a clamping plate portion. The connecting plate portion includes a plate segment and a tongue segment. The plate segment has a first elastic claw, and the tongue segment is located at the top of the plate segment, forming a locking position with the tongue segment. The clamping plate portion extends from the bottom of the plate segment relative to the plate segment, with the tongue segment and the clamping plate portion located on opposite sides of the plate segment, forming a clamping position with the bottom edge. When the spring piece is assembled with the face ring, the tongue segment is inserted into the first slot, the plate portion is inserted into the locking position, and the first elastic claw engages with the first slot.

[0009] As can be seen from the above, the design of the connecting component eliminates the need for fasteners when assembling the face ring and the spring, simplifying the assembly process, improving production efficiency, reducing the number of parts required for assembly, and effectively reducing production costs. In addition, the structural design of the face ring and the spring ensures that the spring is not easily detached from the face ring after assembly without disassembly, guaranteeing the reliability of the connection and reducing the risk of the recessed light assembly with this connecting component falling from the ceiling after assembly, thus ensuring safety during use.

[0010] A preferred embodiment is that the top inner side of the plate is provided with a protrusion; the tongue section is provided with a second elastic claw, which is located below the protrusion and engages with the protrusion.

[0011] As can be seen from the above, this design increases the reliability and strength of the connection between the spring and the face ring, thereby further reducing the risk that the spring will not easily fall off the face ring when not subjected to disassembly operations.

[0012] Another preferred embodiment is that the plate segment includes a body and a tongue, the tongue extending below the body; the bottom edge has a second slot at the tongue, into which the tongue is inserted.

[0013] As can be seen from the above, this design can further increase the reliability and strength of the connection between the spring and the face ring, ensuring that the spring does not separate from the face ring unless disassembled. On the other hand, the cooperation between the tongue and the second slot provides a support point for the elastic deformation of the clamping plate, preventing the spring from detaching from the face ring during the assembly of the connecting components with the ceiling, thus ensuring installation reliability and safety.

[0014] A further design is to provide a third elastic claw on the tongue; and a second slot on the plate at the third elastic claw, with the third elastic claw engaging with the second slot.

[0015] As can be seen from the above, this design can improve the reliability of the further spring and face ring assembly, so as to better support the elastic deformation of the clamping plate and prevent the tongue and face ring from separating from each other without being disassembled.

[0016] A further improvement is to provide a clearance groove between the body and the tongue, with the clearance groove penetrating the plate segment.

[0017] As can be seen from the above, the design of the clearance groove allows the tongue to elastically deform relative to the body, thereby reducing the assembly difficulty of the third elastic claw and the second slot.

[0018] Another further option is to provide a rib at the junction of the ring and the plate, with the rib located on the outside of the ring; the plate is recessed into the ring wall relative to the rib, so that the plate and the rib form a recess, and the second slot is located in the recess.

[0019] As can be seen from the above, the design of the rib increases the structural strength at the junction of the ring and the plate. On the other hand, the recess formed by the plate can limit the spring piece and allow the plate segment to fit closer to the inside of the ring, which helps to reduce the volume of the connecting components. At the same time, it also prevents the plate segment from separating from the plate segment due to impact from external objects.

[0020] Another preferred embodiment is that the clamping plate portion includes a first bent section and a second bent section, the first bent section being connected between the plate section and the second bent section, the first bent section extending upwards from the plate section at an angle away from the plate section, and the second bent section extending upwards or downwards from the extended end of the first bent section at an angle away from the plate section.

[0021] As can be seen from the above, by designing the clamping plate, the mechanical properties of the clamping plate can be optimized, so that the clamping plate has sufficient elasticity to cooperate with the bottom edge to fix the connecting component to the ceiling, and the clamping plate has sufficient structural strength.

[0022] A further option is to bend the extended end of the second bending section toward the bottom edge.

[0023] As can be seen from the above, this design can improve the structural strength of the second bending section and ensure the clamping force of the connecting components.

[0024] A further proposed solution is to have the spring sheet integrally stamped from metal material.

[0025] As can be seen from the above, this design can reduce the difficulty and cost of producing the shrapnel.

[0026] To achieve the second objective of this utility model, this utility model provides an embedded lighting fixture, including the aforementioned connecting components.

[0027] As can be seen from the above, recessed lighting fixtures can simplify the assembly process, reduce the number of parts, and lower production costs by setting up connecting components. Attached Figure Description

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0039] Connection component embodiment Reference Figure 2 and Figure 3 The connecting component 100 includes a face ring 1 and a spring piece 2. In this embodiment, there are two spring pieces 2, which are evenly distributed around the circumference of the face ring 1 and are detachably connected to the face ring 1, making the spring pieces 2 replaceable. When the spring pieces 2 fail, the lifespan of the lamp can be extended by replacing the spring pieces 2, reducing the cost of use and ensuring the firmness of the connection between the connecting component 100 and the ceiling.

[0040] Combination Figure 4The ring 1 includes a ring wall 11 and a bottom edge 12. The bottom edge 12 is circumferentially disposed around the outer periphery of the ring wall 11, and the bottom edge 12 is located at the bottom of the ring wall 11. The ring wall 11 includes a ring portion 111 and a plate portion 112, wherein the number of ring portions 111 and plate portions 112 is equal to the number of spring pieces 2, and the ring portions 111 and plate portions 112 are arranged alternately and connected end to end.

[0041] The plate portion 112 is used for the engagement and connection of the spring piece 2; wherein, the plate portion 112 is provided with a first slot 1121, which preferably extends through the plate portion 112 in the thickness direction to ensure the reliability of the connection between the plate portion 112 and the spring piece 2, and also facilitates the structural forming of the plate portion 112. In addition, at the top of the plate portion 112, a first slot 1110 is formed between the inner side of the plate portion 112 and the ring portion 111.

[0042] Combination Figure 5 and Figure 6 The spring 2 includes a connecting plate portion 21 and a clamping plate portion 22, which are integrally formed. Preferably, the spring 2 is integrally stamped from metal material, which can reduce the forming difficulty of the spring 2 and help reduce production costs.

[0043] The connecting plate portion 21 includes a plate segment 211 and a tongue segment 212. Preferably, the plate segment 211 includes a body 2111 and a tongue 2112. The body 2111 is provided with a first elastic claw 21111, which engages with a first slot 1121 on the plate portion 112. The number of the first elastic claw 21111 and the first slot 1121 can be flexibly adjusted according to the size and structure of the spring piece 2. For example, in this embodiment, there are two first elastic claws 21111 and two first slots 1121, and the two first elastic claws 21111 are located on opposite sides of the tongue 2112. It is understood that in other embodiments, the number of the first elastic claws 21111 and the first slots 1121 may also be three or four.

[0044] Combination Figure 7The tongue 2112 extends into the lower side of the body 2111 in the height direction of the connecting assembly 100. To cooperate with the tongue 2112, the bottom edge 12 of the face ring 1 has a second slot 121 at the tongue 2112. The second slot 121 may or may not penetrate the bottom edge 12 in the height direction of the connecting assembly 100. When the spring piece 2 is assembled with the face ring 1, the first elastic claw 21111 engages with the first slot 1121, and the tongue 2112 is inserted into the second slot 121. By setting the tongue 2112 to cooperate with the second slot 121, on the one hand, the connection strength and reliability between the spring piece 2 and the face ring 1 are increased, ensuring that the spring piece 2 does not easily separate from the face ring 1 without being disassembled, such as preventing the spring piece 2 from separating from the face ring 1 due to external forces (such as the gravity of the lamp body or light-emitting module of the recessed lamp); on the other hand, since the tongue 2112 is close to the connection between the connecting plate portion 21 and the clamping plate portion 22, the tongue 2112 and the second slot The cooperation of 121 can provide a support point for the elastic deformation of the clamping plate 22, and prevent the spring piece 2 from detaching from the face ring 1 due to the elastic deformation of the clamping plate 22. For example, during the assembly of the connecting component 100 with the ceiling, the spring piece 2 needs to undergo a large degree of elastic deformation. The second slot 121 restricts the tongue 2112, preventing the connecting plate 21 from moving in the normal direction of the plate 112, thereby preventing the first elastic claw 21111 from detaching from the first slot 1121, ensuring installation reliability and safety.

[0045] Combination Figure 8 The tongue 2112 is provided with a third elastic claw 21121; correspondingly, the plate portion 112 of the annular wall 11 is provided with a second slot 1123 at the third elastic claw 21121. The second slot 1123 is consistent with the first slot 1121 and penetrates the plate portion 112 in the thickness direction. When the spring piece 2 is assembled with the face ring 1, the third elastic claw 21121 and the second slot 1123 engage and connect. The cooperative design of the third elastic claw 21121 and the second slot 1123 can improve the reliability of the further assembly of the spring piece 2 and the face ring 1, and at the same time better support the elastic deformation of the clamping plate portion 22 of the spring piece 2, so as to better prevent the tongue 2112 and the face ring 1 from separating from each other without being disassembled.

[0046] Furthermore, a clearance groove 2113 is provided between the body 2111 of the plate segment 211 and the tongue 2112, that is, clearance grooves 2113 are provided on both opposite sides of the tongue 2112. The clearance grooves 2113 are located between the body 2111 and the tongue 2112, and the clearance grooves 2113 penetrate the plate segment 211 in the thickness direction. The provision of the clearance grooves 2113 allows the tongue 2112 to elastically deform relative to the body 2111, thereby reducing the difficulty of inserting the tongue 2112 into the second slot 121, and / or reducing the difficulty of engaging the third elastic claw 21121 with the second slot 1123.

[0047] Combination Figure 9 The tongue segment 212 is connected to the top of the plate portion 112 and the body 2111 of the plate portion 211; wherein, a locking position 210 is formed between the tongue segment 212 and the plate portion 211. When the spring piece 2 is assembled with the face ring 1, the tongue segment 212 is inserted into the first slot 1110 formed by the ring portion 111 and the plate portion 112. Correspondingly, the plate portion 112 is inserted into the locking position 210 to restrict the plate portion 211 from moving in the normal direction of the plate portion 112 at the top of the plate portion 211.

[0048] Preferably, the top inner side of the plate portion 112 is provided with a protrusion 1122; correspondingly, the tongue section 212 is provided with a second elastic claw 2121. When the spring piece 2 is assembled with the face ring 1, the second elastic claw 2121 is located below the protrusion 1122 and engages with the protrusion 1122. This design enhances the reliability and strength of the connection between the spring piece 2 and the face ring 1, thereby further reducing the risk that the spring piece 2 will not easily fall off the face ring 1 without being disassembled.

[0049] The clamping plate portion 22 extends from the bottom of the plate segment 211, bent relative to the plate segment 211, and the tongue portion 212 and the clamping plate portion 22 are located on opposite sides of the plate segment 211. A clamping position 20 is formed between the clamping plate portion 22 and the bottom edge 12.

[0050] The clamping plate portion 22 includes a first bent section 221 and a second bent section 222. The first bent section 221 connects between the plate section 211 and the second bent section 222. The first bent section 221 extends obliquely upwards from the plate section 211, while the second bent section 222 extends obliquely upwards or downwards from the extended end of the first bent section 221. Through the design of the first bent section 221 and the second bent section 222, the mechanical properties of the clamping plate portion 22 can be optimized, enabling it to have sufficient elasticity to cooperate with the bottom edge 12 to fix the connecting assembly 100 to the ceiling, and also ensuring sufficient structural strength. Furthermore, the extended end of the second bent section 222 bends towards the bottom edge 12 to enhance its structural strength and ensure the clamping force of the connecting assembly 100.

[0051] Furthermore, a rib 113 is provided at the junction of the ring portion 111 and the plate portion 112, with the rib 113 located on the outer side of the ring portion 111. The plate portion 112 is recessed into the ring wall 11 relative to the rib 113, forming a recess 1130, within which the second slot 121 is located. The design of the rib 113 increases the structural strength at the junction of the ring portion 111 and the plate portion 112, preventing the ring wall 11 from cracking due to stress at this junction; it also helps to limit the movement of the spring piece 2 in conjunction with the recess 1130 formed by the plate portion 112, allowing the plate segment 211 to fit closer to the inside of the ring 1, which helps to reduce the volume of the connecting assembly 100, while also preventing the plate segment 211 from separating from the plate portion 112 due to impact from external objects.

[0052] In summary, the design of the connecting component 100 eliminates the need for fasteners (such as bolts or rivets) when assembling the face ring 1 and the spring piece 2. This simplifies the assembly process, improves production efficiency, and reduces the number of parts required for assembly, effectively lowering production costs. Furthermore, the structural design of the face ring 1 and the spring piece 2 ensures that the spring piece 2 is unlikely to detach from the face ring 1 after assembly without disassembly, guaranteeing the reliability of the connection and reducing the risk of the recessed light assembly equipped with this connecting component 100 falling from the ceiling after installation, thus ensuring safety during use.

[0053] Recessed Lighting Fixture Examples Reference Figure 10 The recessed lighting fixture 3 includes the connecting component 100 described in the above-mentioned connecting component embodiment. By setting the connecting component 100, the assembly process of the recessed lighting fixture 3 can be simplified and the number of parts can be reduced, thereby improving production efficiency and reducing production costs.

[0054] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
