Description
Technical Field
[0001] This utility model relates to the field of lighting fixture assembly technology, and in particular to a locking ring switching structure for a lighting fixture and a lighting fixture. Background Technology
[0002] In existing technologies, ceiling lights and semi-ceiling lights are widely used in lighting fixtures. Compared to chandeliers, ceiling lights and semi-ceiling lights require less space because their mounting surface is flush with the wall, and they are less prone to dust accumulation, making cleaning easier. However, ceiling lights and semi-ceiling lights have a limited range of shapes and are relatively less aesthetically pleasing in terms of decoration.
[0003] To overcome this shortcoming, retaining rings can be installed on ceiling lights and semi-ceiling lights. These rings are fitted around the outside of the light fixture, providing different visual effects and enhancing the overall aesthetic appeal. However, because the mounting surface is close to the wall, the current technology makes it difficult to install or remove retaining rings on ceiling lights or semi-ceiling lights. Replacement is often difficult after installation, hindering widespread application.
[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0006] The technical solution of this utility model is as follows:
[0007] The first aspect of this utility model provides a retaining ring switching structure for connecting a lamp to different retaining rings. The retaining ring switching structure includes a lamp connecting structure disposed on the lamp, a retaining ring connecting structure disposed on the retaining ring, and a connector disposed between the lamp and the retaining ring. The connector includes:
[0008] The body is configured to match the shape of the lamp;
[0009] A first connecting structure is disposed on the side of the body corresponding to the lamp and is matched with the lamp connecting structure to realize the detachable connection between the connector and the lamp.

[0011] In one embodiment, the first connecting structure is a protruding rib extending perpendicularly from the body to the lamp, and the lamp connecting structure is a slot that matches the protruding rib, wherein the protruding rib is inserted into the slot to achieve a detachable connection between the connector and the lamp.
[0012] In one embodiment, the cross section of the rib perpendicular to the extension direction is parabolic, and the slot is a parabolic slot corresponding to the rib, so as to restrict the relative movement between the connector and the lamp after the rib is inserted into the slot.
[0013] In one embodiment, the body forms a handle in a direction opposite to the extension of the rib to facilitate inserting the rib into the slot and removing the rib from the slot.
[0014] In one embodiment, the retaining ring connection structure includes:
[0015] A base, which extends inward perpendicularly to the retaining ring, to support the lamp;
[0016] The retaining protrusion is fixed to the inner side of the retaining ring and forms a retaining groove with the base. The retaining ring is detachably connected to the connector through the retaining groove.
[0017] In one embodiment, the second connecting structure is a convex rail extending in a helical direction, which is screwed into the slot to achieve a detachable connection between the connector and the retaining ring.
[0018] In one embodiment, the lowest end of the vertical convex rail protrudes to form a stop to prevent the retaining ring from slipping off the connector.

[0020] In one embodiment, the retaining ring switching structure includes two or more of the connecting members, and the same number of the lamp connecting structures are symmetrically provided on the lamp, and the same number of the retaining ring connecting structures are symmetrically provided on the retaining ring.
[0021] The second aspect of this utility model provides a lighting fixture, wherein the lighting fixture and the retaining ring are connected by a retaining ring switching structure as described in any of the preceding claims.
[0022] This utility model provides a joist switching structure for a lamp and a lighting fixture. The joist switching structure is used to connect a lamp with different joists, including a lamp connecting structure disposed on the lamp, a joist connecting structure disposed on the joist, and a connector disposed between the lamp and the joist.

[0032] This utility model provides a retaining ring switching structure for a lamp and a lighting fixture. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following provides a more detailed description of this utility model. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit this utility model.
[0033] It should be noted that the terms "center", "upper", "lower", "left", "right", "inner", "outer", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation or must be constructed in a specific orientation.

[0035] Ceiling lights, because their mounting surface is flush against the wall, effectively prevent dust from entering. Furthermore, avoiding exposure of the installation structure enhances the visual appeal, making the entire space more concise and aesthetically pleasing. For semi-ceiling lights, adding retaining rings can provide a similar visual effect to ceiling lights. Using replaceable retaining rings with the light fixture allows for different visual effects for ceiling and semi-ceiling lights, avoiding a monotonous appearance. However, because the mounting surface is flush against the wall, ceiling or semi-ceiling lights often require specialized tools for installation and removal. This undoubtedly increases the difficulty of removing and installing retaining rings, affecting the efficiency of ring replacement and hindering the market application of replaceable retaining rings.
[0036] To address the above technical problems, this utility model provides a retaining ring connection structure for lamps. The lamp and retaining ring are installed by cooperating with connecting components and connecting structures respectively set on the lamp and retaining ring, reducing the operating space required for removing and installing the retaining ring. The lamp and retaining ring can be installed and removed without removing the lamp from the mounting surface. This allows for convenient and quick removal and installation of the retaining ring even when the lamp mounting surface is close to the wall, ensuring efficient replacement of the retaining ring and facilitating further market promotion.
[0037] Specifically, such as Figure 1 and Figure 2 As shown, this utility model discloses a retaining ring switching structure for connecting a lamp 400 with retaining rings 500 of different appearances. The retaining ring switching structure includes a lamp connecting structure 100 disposed on the lamp 400, a retaining ring connecting structure 200 disposed on the retaining ring 500, and a connector 300 disposed between the lamp 400 and the retaining ring 500. The connector 300 includes a body 310, a first connecting structure 320, and a second connecting structure 330. The body 310 is shaped to match the lamp 400. The first connecting structure 320 is located on the side of the body 310 corresponding to the lamp 400 and is matched with the lamp connecting structure 100 to achieve a detachable connection between the connector 300 and the lamp 400. The second connecting structure 330 is located on the side of the body 310 corresponding to the retaining ring 500 and is matched with the retaining ring connecting structure 200 to achieve a detachable connection between the connector 300 and the retaining ring 500. Thus, the lamp 400 is connected to retaining rings 500 of different appearances via the connector 300. Using the connector 300 as a connecting tool between the lamp 400 and the retaining ring 500 eliminates the need to remove the lamp 400 from the mounting surface when installing or removing the retaining ring 500, reducing the space required for operation, simplifying the installation and removal process, and allowing users to easily replace different retaining rings installed on the lamp as needed.
[0038] In one implementation, such as Figure 5 and Figure 7As shown, the first connecting structure 320 is a protruding rib 321 extending perpendicularly from the body 310 towards the lamp 400. The lamp connecting structure 100 is a slot 101 that matches the protruding rib 321. The protruding rib 321 is inserted into the slot 101 to achieve a detachable connection between the connector 300 and the lamp 400. By setting a protruding rib 321 extending in a specific direction and a corresponding matching slot 101, the connection between the connector 300 and the lamp can be achieved with a simple structure. Optionally, the width of the slot 101 is set to be slightly smaller than the thickness of the rib 321, or the inclination angle inside the slot 101 is at a slight angle to the extension direction of the rib 321, thereby achieving a detachable connection between the slot 101 and the rib 321 through an interference fit. This ensures that after the rib 321 is inserted into the slot 101, the connector 300 will not move along the direction of the rib 321 without the application of external force, thus improving the stability after installation.
[0039] In one implementation, such as Figure 2 and Figure 7 As shown, the cross-section of the rib 321 perpendicular to the extension direction is parabolic, and the first connecting structure 320 is a parabolic slot corresponding to the rib 321, i.e., a parabolic slot 101, to restrict the relative movement between the connector 300 and the lamp 400 after the rib 321 is inserted into the slot 101. By setting the parabolic rib 321 and slot 101, after the rib 321 is inserted into the slot 101, the movement of the rib 321 in the plane perpendicular to the extension direction is restricted, and the connector 300 can only move relative to the lamp 400 along the first connecting structure 320, i.e., the extension direction of the rib 321, thereby ensuring that no relative displacement occurs between the connector 300 and the lamp 400 during the installation of the retaining ring 500.
[0040] In one implementation, such as Figure 5 and Figure 6 As shown, the body 310 forms a handle 311 in the extending direction opposite to the protruding rib 321 to facilitate inserting the protruding rib 321 into the slot 101 and pulling the protruding rib 321 out of the slot 101. The handle 311 is positioned above the protruding rib 321, so that the handle 311 and the protruding rib 321 form a vertical line, making it easier and more convenient for the user to insert and pull the protruding rib 321 into the slot 101.
[0041] In one implementation, such as Figure 2 and Figure 4As shown, the retaining ring connection structure 200 includes a base 210, a retaining protrusion 220, and a retaining groove 230. The base 210 extends inward perpendicularly to the retaining ring 500 to support the lamp 400. The retaining protrusion 220 is fixed to the inner side of the retaining ring 500 and forms the retaining groove 230 with the base 210. The retaining ring 500 is detachably connected to the connector 300 through the retaining groove 230. The base 210 supports the lamp 400. When installing the retaining ring 500, the relative position between the retaining ring 500 and the lamp 400 is ensured. Then, through the retaining groove 230 formed between the retaining protrusion 220 and the base 210, a retaining ring connection structure 200 matching the second connection structure 330 on the connector 300 is formed, realizing a detachable connection between the retaining ring 500 and the connector 300, thereby realizing a detachable connection between the retaining ring 500 and the lamp 400.
[0042] In one implementation, such as Figure 5 and Figure 8 As shown, the second connecting structure 330 is a convex rail 331 extending along a spiral direction. The convex rail 331 is screwed into the slot 230 to achieve a detachable connection between the connector 300 and the retaining ring 500. By setting the convex rail 331 with a matching spiral structure, the second connecting structure 330 is a thread-like structure on the body 310 facing the retaining ring 500. Thus, after placing the lamp 400 on the base 210, rotating the retaining ring 500 will engage the convex rail 331 into the slot 230 formed between the protruding protrusion 220 and the base 210. The detachable connection between the connector 300 and the retaining ring 500 is achieved through the cooperation of the protruding protrusion 220, the base 210, and the convex rail 331.
[0043] In one implementation, such as Figure 8 and Figure 9As shown, the lowest end 332 of the vertical convex rail 331 protrudes to form a stop 334 to prevent the retaining ring 500 from slipping off the connector 300. After rotating the retaining ring 500 to engage the convex rail 331 of the second connecting structure 330 into the slot 230 between the base 210 and the retaining protrusion 220, the retaining ring 500 is fixedly installed in place with the lamp 400. During use, due to its own weight and possible vibration, the retaining ring 500 and the lamp 400 may experience relative displacement. The retaining ring 500 slides downward relative to the lamp 400 and the connector 300. At this time, the retaining protrusion 220 moves along the convex rail 331 to the lowest end 332 and is blocked by the stop 334 at the lowest end 332, preventing further slippage that could cause the retaining ring 500 to detach from the lamp 400, thus ensuring safety and stability during use.
[0044] In one implementation, such as Figure 2 As shown, the retaining protrusion 220 is parabolic in shape, and the retaining groove 230 is formed between the lowest point of the retaining protrusion 220 and the base 210. By setting the retaining protrusion 220 as parabolic, the processing difficulty is reduced while ensuring the mechanical strength of the retaining protrusion 220. This ensures that after the retaining ring 500 and the lamp 400 are installed in place, the retaining protrusion 220 abuts against the convex rail 331 of the second connecting structure 330, maintaining the installation stability of the retaining ring 500.
[0045] In one implementation, such as Figure 1 and Figure 2 As shown, the retaining ring switching structure includes two or more connectors 300, and the same number of lamp connecting structures 100 are symmetrically arranged on the lamp 400, and the same number of retaining ring connecting structures 200 are symmetrically arranged on the retaining ring 500. A plurality of lamp connecting structures 100 are symmetrically arranged about the central axis of the lamp 400, and a plurality of retaining ring connecting structures 200 are symmetrically arranged about the central axis of the retaining ring 500. The number of lamp connecting structures 100, retaining ring connecting structures 200, and connectors 300 are equal to ensure the balance of the overall structure after the retaining ring 500 is connected to the lamp 400, and to improve the stability of the retaining ring 500 after installation.
[0046] The locking ring switching structure of the lamp described in this utility model has a lamp connecting structure 100 on the lamp 400, a locking ring connecting structure 200 on the locking ring 500, and a first connecting structure 320 on the connector 300 corresponding to the lamp connecting structure 100 and a second connecting structure 330 corresponding to the locking ring connecting structure 200. After the connector 300 is fixed to the lamp 400 by the first connecting structure 320 and the lamp connecting structure 100, the locking ring 500 is rotated so that the second connecting structure 330 engages with the locking ring connecting structure 200, thereby achieving the fixed installation of the locking ring 500 and the lamp 400. The locking ring 500 can be installed and removed without removing the lamp 400 from the mounting surface, which is convenient and quick to operate. This allows users to change the locking ring installed on the lamp at any time as needed, thereby providing different visual effects.
[0047] This utility model also provides a lighting fixture, such as Figure 1 and Figure 3 As shown, the lighting fixture is provided with a retaining ring switching structure as described above to connect the lighting fixture 400 and the retaining ring 500, thereby enabling the quick installation and disassembly of the lighting fixture 400 and the retaining ring 500.
[0048] The following describes the structural details of the snap ring switching structure and the lighting fixture equipped with the snap ring switching structure of this utility model with reference to specific embodiments.
[0049] In this embodiment, the lamp 400 and the retaining ring 500 are assembled into a lighting fixture using a retaining ring switching structure. Specifically, the retaining ring switching structure includes a lamp connecting structure 100, a retaining ring connecting structure 200, and a connector 300. After the connector 300 is fixed to the lamp 400 by the first connecting structure 320 and the lamp connecting structure 100, the retaining ring 500 is rotated so that the second connecting structure 330 engages with the retaining ring connecting structure 200, thereby achieving a fixed installation of the retaining ring 500 and the lamp 400.
[0050] Specifically, such as Figure 2As shown, a lamp connection structure 100 is provided on the top of the lamp 400, i.e., on the mounting surface with the wall. Further, the lamp connection structure 100 is a parabolic slot 101, extending downwards perpendicularly to the top surface of the lamp 400. In this embodiment, the lamp 400 has a disc-shaped structure. On the top of the lamp 400, with the center of the lamp 400 as the center of symmetry, three lamp connection structures 100, i.e., three parabolic slots 101, are symmetrically arranged. The line connecting any two adjacent slots 101 to the center of the lamp 400 differs by 120° to ensure a balanced and stable connection when the retaining ring 500 is installed.
[0051] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, three connectors 300 are provided corresponding to the three lamp connection structures 100 provided on the lamp 400. Each connector 300 includes a body 310 that matches the structure of the lamp 400, a first connection structure 320 provided on the body 310 facing the lamp 400, and a second connection structure 330 provided on the body 310 facing the retaining ring 500.
[0052] Specifically, in this embodiment, the body 310 is provided with a flat plate parallel to the top surface of the lamp 400 and an arc-shaped plate perpendicular to the flat plate and parallel to the side wall of the lamp 400. The flat plate extends vertically toward the top surface of the lamp 400 to form a rib 321 as the first connecting structure 320, and the rib 321 is shaped to match the slot 101, meaning the cross-section of the rib 321 in the vertical extension direction is parabolic. After the rib 321 is inserted into the slot 101, the parabolic shape restricts the movement of the connector 300 in the horizontal direction. When the second connecting structure 330 engages with the retaining ring connection structure 200 on the retaining ring 500, the rib 321, under torque, engages with the slot 101, further restricting the vertical movement of the connector 300, thereby achieving a fixed and stable connection between the connector 300 and the lamp 400. In other embodiments, the connector 300 and the lamp 400 can be fixed by interference fit by adjusting the width and tilt angle of the slot 101 relative to the rib 321.
[0053] Furthermore, such as Figure 5 and Figure 6As shown, a handle 311 is formed by a vertically upward protrusion on the flat plate of the body 310 corresponding to the rib 321, facilitating the user to insert the rib 321 into the slot 101 and to pull the rib 321 out of the slot 101. In this embodiment, the handle 311 is a notch formed by the upward arching of the flat plate, allowing the user to grip and apply force to insert the rib 321 into the slot 101 to fix the connector 300 to the lamp 400, and to pull the rib 321 out of the slot 101 to separate the connector 300 from the lamp 400. The handle 311 is positioned directly above the rib 321 for easy application of force by the user.
[0054] Furthermore, such as Figure 5 As shown, the arc panel of the body 310 facing the retaining ring 500 is provided with a second connecting structure 330. In this embodiment, as... Figure 8 and Figure 9 As shown, the second connecting structure 330 is a convex rail 331 extending helically perpendicular to the arc panel. The convex rail 331 extends circumferentially downwards along the arc panel, forming a sloped structure from the highest point 333 to the lowest point 332. A stop 334 is vertically provided at the lowest point 332. After the connecting member 300 is fixedly connected to the retaining ring 500 via the convex rail 331, the stop 334 prevents the corresponding structure within the retaining ring 500 from detaching from the lowest point 332. In this embodiment, in the second connecting structure 330, a slope is formed on the convex rail 331 between the highest point 333 and the lowest point 332, and a flat section is formed at the lowest point 332 to control the speed of the retaining ring 500 after sliding along the convex rail 331, preventing it from detaching from the stop 334.
[0055] Furthermore, such as Figure 2 As shown, in this embodiment, the retaining ring 500 is a ring structure corresponding to the lamp 400, and the inner diameter of the retaining ring 500 is larger than the outer diameter of the lamp 400. A base support 210 extends vertically inward from the bottom of the retaining ring 500, and a through hole is formed in the base support 210 to expose the lighting portion of the lamp 400, while simultaneously supporting the lamp 400 to ensure the retaining ring 500 is fixedly installed on the lamp 400. Specifically, as... Figure 4As shown, a locking protrusion 220 is provided above the base 210, and a locking groove 230 is formed between the locking protrusion 220 and the base 210. The connector 300 and the retaining ring 500 can be locked together by inserting the protruding rib 321 into the locking groove 230. Specifically, when the lamp 400 is placed on the base 210, the height between the lowest end 332 of the protruding rail 331 and the base 210 is less than the height between the locking protrusion 220 and the base 210, and the height between the highest end 333 of the protruding rail 331 and the base 210 is greater than the height between the locking protrusion 220 and the base 210, ensuring that the protruding rail 331 can be screwed into the locking groove 230 and held stably.
[0056] Specifically, such as Figure 2 As shown, the latching protrusion 220 is a parabolic protrusion with its opening facing upwards, and its lowest point corresponds to the base 210 to form the latching groove 230. After the lamp 400 with the connector 300 installed is placed into the retaining ring 500, rotating the retaining ring 500 will cause the second connecting structure 330, i.e., the convex rail 331, on the connector 300 to rotate into the latching groove 230. The latching protrusion 220 and the base 210 cooperate to lock the convex rail 331, thereby achieving the locking connection between the connector 300 and the retaining ring 500, and installing the retaining ring 500 and the lamp 400 into place. In this embodiment, setting the latching protrusion 220 as a parabolic structure can enhance the mechanical strength of the structure and avoid damage to the latching protrusion 220 due to excessive force during installation, which would affect the stable installation of the retaining ring 500. After the retaining ring 500 and the lamp 400 are installed and put into use, if the retaining ring 500 undergoes relative displacement with the lamp 400 under the action of gravity, that is, the retaining protrusion 220 slides along the protrusion rail 331, then the retaining protrusion 220 will eventually abut against the stop member 334 at the lowest end 332 of the protrusion rail 331, preventing the retaining ring 500 from sliding down further and separating from the lamp 400, thereby ensuring a stable connection between the retaining ring 500 and the lamp 400.
[0057] The retaining ring switching structure of the lamp described in this utility model uses the connector 300 as a connecting tool between the lamp 400 and the retaining ring 500. When installing or removing the retaining ring 500, it is not necessary to remove the lamp 400 from the mounting surface, which reduces the space required for operation, simplifies the difficulty of installation and removal, and makes it convenient for users to change different retaining rings installed on the lamp as needed.
[0058] The following is a brief description of the use of the snap ring switching structure described in this utility model:
[0059] First, connect the connector to the lamp fixture. Based on the number of connecting structures on the lamp fixture, insert the first connecting structure into the corresponding connecting structure on the lamp fixture using the same number of connectors in a one-to-one manner. The handles on the connectors allow for quick insertion and removal of the protruding ribs from the lamp fixture's connecting structure slots. Next, place the lamp fixture with the connector installed into the retaining ring. The base supports the lamp fixture, ensuring that each connector on the lamp fixture corresponds to a corresponding protrusion on the retaining ring. The lowest point of the protruding rail of the second connecting structure on the connector faces the groove between the protrusion and the base. Rotate the retaining ring or the lamp fixture to allow the protruding rail of the second connecting structure to rotate into the groove and abut against the protrusion, thus securing the retaining ring and connector and installing the lamp fixture. After the lamp fixture is in place, the retaining ring slides downwards under gravity, causing the protrusion to move along the inclined direction of the protruding rail and eventually abut against the stop, preventing the retaining ring from falling off the connector and ensuring a stable connection between the retaining ring and the lamp fixture. When the retaining ring needs to be replaced, there is no need to remove the lamp from the mounting position. Simply lift the retaining ring slightly to separate the retaining protrusion from the stop, and then rotate the retaining ring in the opposite direction of installation to detach it from the lamp. You can replace it with retaining rings of different shapes and appearances as needed to provide different visual experiences for the lamp.
[0060] Therefore, the retaining ring switching structure of the lamp described in this utility model can quickly realize the disassembly and assembly of the connector and the lamp through the cooperation of the first connecting structure and the lamp connecting structure, and can quickly realize the disassembly and assembly of the connector and the retaining ring through the cooperation of the second connecting structure and the retaining ring connecting structure. Thus, the disassembly and assembly of the retaining ring and the lamp can be realized without additional operating space, reducing the difficulty of the assembly and disassembly process, improving the efficiency of the retaining ring assembly and disassembly, and making it convenient for users to change the retaining ring they need at will, providing different visual effects for the lighting fixture.
[0061] In summary, this utility model provides a joist switching structure for a lamp and a lighting fixture. The joist switching structure is used to connect a lamp with different joists, including a lamp connecting structure disposed on the lamp, a joist connecting structure disposed on the joist, and a connector disposed between the lamp and the joist.
