Description

Technical Field

[0001] This utility model specifically relates to a lamp mounting structure. Background Technology

[0002] With the development of lighting technology, modern indoor lighting fixtures (such as ceiling lights and chandeliers) not only require excellent optical performance and energy efficiency, but also place higher demands on the convenience, stability, and aesthetics of their installation structure. Traditional lighting fixtures are usually installed piece by piece on-site, which involves assembling the lamp panel, light source, connectors, and lampshade sequentially in a high-altitude work environment. This method is cumbersome, time-consuming, and inconvenient to operate, especially when working at heights, which is not only inefficient but also increases construction safety risks.

[0003] While some existing lighting fixture installation structures employ modular designs to simplify assembly, they generally suffer from issues such as insecure connections, easy loosening, and difficulty in disassembly. For example, some fixtures achieve quick installation using clips or spring structures, but these are prone to loosening due to vibration or thermal expansion and contraction during long-term use, affecting safety. Furthermore, some installation structures require high precision in the position of ceiling-embedded components, lacking adjustment margins, leading to difficulties in alignment or uneven stress during installation, affecting the levelness and overall stability of the fixture.

[0004] Furthermore, the connection between the lampshade and the lamp panel often relies on screws or clips for fixing, which frequently requires tools for installation and can easily leave stress concentration points on the light-transmitting plate, affecting the appearance quality and sealing performance. How to achieve rapid assembly, reliable fixing, and convenient maintenance of lighting fixtures while ensuring structural strength has become a key technical challenge in current lighting product design.

[0005] This utility model was developed precisely because of the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a lamp installation structure with high disassembly and assembly efficiency and stable and reliable structure.

[0007] This utility model is achieved through the following technical solution:

[0008] This utility model provides a lamp mounting structure, including a mounting bracket for connecting to a support body, a connecting bracket located below the mounting bracket, a lamp panel bracket located below the connecting bracket for mounting light-emitting elements, and a lampshade assembly located below the lamp panel bracket for covering the light-emitting elements. The lampshade assembly is connected to the lower side of the lamp panel bracket. The lampshade assembly is connected to the lower surface of the lamp panel bracket, and a mounting post is connected to the upper surface of the lamp panel bracket. The mounting post has a threaded hole. The connecting bracket has a mounting sleeve that fits onto the mounting post from top to bottom. The mounting sleeve has mounting holes corresponding to the threaded holes. The connecting bracket and the lamp panel bracket are fixed by a first fastener passing through the mounting holes and engaging with the threaded holes. The connecting bracket, the lamp panel bracket, and the lampshade assembly are connected to form a pre-installed assembly. The connecting bracket is connected to the mounting bracket through a detachable connection structure, thereby connecting the pre-installed assembly to the mounting bracket.

[0009] As described above, the mounting structure of the lamp has at least two strip-shaped mounting holes, the length of which is radially arranged, and the mounting bracket is connected to the support body by a second fastener passing through the strip-shaped mounting holes.

[0010] As described above, the mounting bracket has at least two circumferentially distributed snap-fit ​​parts, and the connecting bracket has axial grooves that correspond one-to-one with the snap-fit ​​parts and are open at the top, so that the snap-fit ​​parts can slide vertically into them from top to bottom. The axial grooves are connected to circumferential grooves. When the snap-fit ​​parts enter the axial grooves, the pre-installation components are rotated to make the snap-fit ​​parts slide from the axial grooves into the circumferential grooves, thereby connecting the pre-installation components to the mounting bracket.

[0011] As described above, the lamp mounting structure has several pre-tightening ribs on the side wall of the circumferential groove.

[0012] As described above, the lampshade assembly includes a lampshade bracket, a light-transmitting plate, and a fixing strip. The lampshade bracket is a hollow ring structure. The inner sidewall of the lampshade bracket is provided with a support ring for supporting the light-transmitting plate and a fixing ring located above the support ring. The light-transmitting plate abuts against the support ring. The fixing strip is an elastic ring structure and is installed between the upper surface of the light-transmitting plate and the lower surface of the fixing ring.

[0013] In the lamp installation structure described above, both the lampshade bracket and the lamp panel bracket are circular, and the outer contour of the lampshade bracket matches the lamp panel bracket.

[0014] As described above, in the lamp mounting structure, the lamp panel bracket is made of a one-piece plate structure of metal, and the mounting column is welded to the lamp panel bracket.

[0015] As described above, the mounting sleeve and connecting bracket of the lamp installation structure are an integral structure made of plastic.

[0016] In the lamp mounting structure described above, the strip-shaped mounting holes are evenly distributed around the circumference on the mounting bracket, and the mounting bracket is provided with a thickened portion that extends radially and is distributed circumferentially, with the strip-shaped mounting holes formed on the thickened portion.

[0017] As described above, the mounting structure for the lamps includes a reinforcing plate surrounding each of the strip-shaped mounting holes.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. Improved installation and disassembly efficiency: This lighting fixture installation structure adopts the concept of pre-installed components and achieves convenient installation and disassembly of the fixture through a quick-connect mechanism (axial insertion + circumferential locking). This design not only simplifies the on-site installation process but also allows a single person to complete the operation without tools, greatly improving work efficiency and facilitating future maintenance and replacement.

[0020] 2. Enhanced structural stability and reliability: The use of mounting sleeves and mounting posts, the securing of the first fastener, and the design of the snap-fit ​​part and circumferential groove make the connections between components more robust and stable. In particular, the application of pre-tightening ribs increases additional friction, preventing loosening due to vibration or temperature changes and ensuring the long-term stability of the entire lighting fixture installation structure.

[0021] 3. Optimized adaptability and aesthetics: The strip-shaped mounting hole design allows for adjustment of the second fastener's position within a certain range, improving adaptability to differences in the spacing of embedded bolts or suspension rods in different building structures. Furthermore, the lampshade bracket and lamp panel bracket feature a circular design with matching outer contours, ensuring not only the overall aesthetic appeal of the lamp fixture but also enhancing the integrated and seamless splicing effect during assembly. These features work together to make the lamp fixture both practical and beautiful. Attached Figure Description

[0027] The utility model will be further described below with reference to the accompanying drawings:

[0028] The orientations described in this utility model specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the utility model and are not a limitation on its implementation.

[0029] This embodiment describes a lamp mounting structure, such as... Figure 1 As shown, it is mainly used in ceiling lights, chandeliers, and other lighting fixtures, and is installed and connected to a supporting structure A such as a ceiling or cavity. Figures 2 to 4As shown, this structure includes a mounting bracket 1 for connection to a support A, a connecting bracket 2 located below the mounting bracket 1, a lamp holder 3 located below the connecting bracket 2 for mounting the light-emitting element 5, and a lampshade assembly 4 located below the lamp holder 3 for covering the light-emitting element 5. The lampshade assembly 4 is connected to the lower side of the lamp holder 3. The lamp holder 3 has a lampshade assembly 4 connected to its lower surface and a mounting post 31 connected to its upper surface. The mounting post 31 has a threaded hole 32. The connecting bracket 2 has a mounting sleeve 21 that fits onto the mounting post 31 from top to bottom. The mounting sleeve 21 has a mounting hole 22 corresponding to the threaded hole 32. The connecting bracket 2 and the lamp holder 3 are fixed by a first fastener 6 passing through the mounting hole 22 and engaging with the threaded hole 32. The connecting bracket 2, the lamp holder 3, and the lampshade assembly 4 are connected to form a pre-installed assembly. The connecting bracket 2 is connected to the mounting bracket 1 through a detachable connection structure, thereby connecting the pre-installed assembly to the mounting bracket 1. By engaging the mounting sleeve 21 with the mounting post 31 and securing it with the first fastener 6, the connecting bracket 2 is stably connected to the lamp holder 3. This assembly, consisting of the connecting bracket 2, lamp holder 3, and lampshade assembly 4, forms a robust and stable pre-installed component. The pre-installed component is then connected to the mounting bracket 1, resulting in a compact structure and a secure, stable installation. This lighting fixture installation structure adopts a "pre-installed component + quick-connect" design concept. The lamp holder 3, connecting bracket 2, and lampshade assembly 4 are pre-assembled into a single unit—the "pre-installed component"—either at the factory or on-site. The core connection method is as follows: the connecting bracket 2 is fitted onto the mounting post 31 on the lamp holder 3 via the mounting sleeve 21, and the first fastener 6 (such as a screw) passes through the mounting hole 22 and screws into the threaded hole 32 for axial locking. This structure ensures the rigidity and stability of the connections between the internal components of the pre-installed component. Subsequently, the pre-installed component is finally assembled with a support structure such as a ceiling through a detachable connection between the connecting bracket 2 and the mounting bracket 1. Mounting bracket 1 is pre-fixed to support body A to form a fixed base. The pre-installed components are then hung by axial insertion and rotation snap-fit, realizing a modular installation process of "pre-installation followed by hanging". This achieves modular assembly, improving production and installation efficiency; the pre-installed components have strong integrity, avoiding the risk of loosening caused by on-site installation; the structural hierarchy is clear, facilitating maintenance and replacement; the installation process is safe and convenient, reducing the difficulty and time cost of high-altitude operations.

[0030] In order to install the mounting bracket 1 on the support body A, as follows Figures 2 to 4As shown, the mounting bracket 1 has at least two strip-shaped mounting holes 11, which are arranged radially along their length. The mounting bracket 1 is connected to the support body A via a second fastener 7 passing through the strip-shaped mounting holes 11. The strip-shaped mounting holes 11 extend radially, allowing the second fastener 7 to be adjusted radially within a certain range. This design accommodates minor differences in the spacing of pre-embedded bolts or suspension rods in different building structures, improving the compatibility of the mounting bracket 1 with different installation scenarios. By adjusting the position of the fastener in the strip-shaped holes, the mounting bracket 1 can be centered and the stress can be evenly distributed. This improves installation adaptability and is suitable for various ceiling structures; it allows for installation error compensation, avoiding rework due to mismatched holes; and it helps to achieve horizontal alignment of the light fixture, improving aesthetics.

[0031] As a preferred option, such as Figures 2 to 4 As shown, the mounting bracket 1 has at least two circumferentially distributed snap-fit ​​parts 12. The connecting bracket 2 has axial grooves 23 that correspond one-to-one with the snap-fit ​​parts 12 and are open at the top, allowing the snap-fit ​​parts 12 to slide vertically from top to bottom. The axial grooves 23 are connected to circumferential grooves 24. When the snap-fit ​​part 12 enters the axial groove 23, the pre-installation component is rotated to allow the snap-fit ​​part 12 to slide from the axial groove 23 into the circumferential groove 24, thereby connecting the pre-installation component to the mounting bracket 1. This ensures that the pre-installation component is stably installed and fixed on the mounting bracket 1, thus achieving the installation connection. Conversely, when disassembly is required, it can also be quickly disassembled by rotating the pre-installation component. While ensuring the stability of the structure, the structure is compact and the efficiency of installation and disassembly is improved. This snap-fit ​​structure adopts a quick-installation mechanism of "axial insertion + circumferential locking". The locking part 12 (such as a boss or hook) slides axially into the axial groove 23. After reaching the bottom, the pre-installed component is rotated so that the locking part 12 rotates into the circumferential groove 24 that communicates with it, completing the circumferential positioning. The extension angle of the circumferential groove 24 determines the rotation angle (usually 15° to 45°), restricting the degree of freedom of the pre-installed component in the working state and preventing accidental detachment. Installation requires no tools, and a single person can complete the high-altitude hanging; disassembly is convenient, facilitating cleaning, maintenance, or replacement of the light source.

[0032] As a further optimized implementation method, such as Figure 5As shown, the sidewall of the circumferential groove 24 is provided with several pre-tightening ribs 241 to increase the friction between the locking part 12 and the sidewall of the circumferential groove 24. The ribs are arranged in a fine stripe or dot matrix pattern, which can significantly improve the static friction coefficient and enhance the anti-loosening effect without significantly increasing the assembly resistance. The pre-tightening ribs 241 are small elastic protrusions, usually integrally injection molded from plastic connecting brackets 2. When the locking part 12 slides into the circumferential groove 24, the ribs undergo slight deformation and generate surface contact pressure with the surface of the locking part 12, forming a continuous frictional pre-tightening force. This structure can effectively suppress the loosening tendency caused by slight vibration of the lamp or temperature changes. It significantly improves the connection stability and prevents loosening after long-term use; no additional anti-loosening parts (such as spring washers) are required, simplifying the structure.

[0033] As a further optimized implementation method, such as Figure 2 As shown, the lampshade assembly 4 includes a lampshade bracket 41, a light-transmitting plate 42, and a fixing strip 43. The lampshade bracket 41 is a hollow annular structure. The inner wall of the lampshade bracket 41 has a support ring 411 for supporting the light-transmitting plate 42, and a fixing ring 412 located above the support ring 411. The light-transmitting plate 42 abuts against the support ring 411. The fixing strip 43 is an elastic annular structure, installed between the upper surface of the light-transmitting plate 42 and the lower surface of the fixing ring 412. Thus, during installation, the light-transmitting plate 42 can be first installed between the support ring 411 and the fixing ring 412, and then the elastic fixing strip 43 can be inserted between the upper surface of the light-transmitting plate 42 and the lower surface of the fixing ring 412, thereby achieving installation and fixation. This lampshade assembly adopts a screwless fixing method of "support + elastic compression". The light-transmitting panel 42 is supported by the lower support ring 411, and a clamping force is applied from above by the elastic fixing strip 43. The fixing strip 43 generates a restoring force after being compressed, firmly pressing the light-transmitting panel 42 onto the support ring 411, forming a stable and reliable sealing structure. The fixing strip 43 can be made of rubber, silicone, or elastic plastic, possessing a certain degree of compression deformation capability. This design avoids drilling holes in the light-transmitting panel, maintaining its aesthetic integrity; installation is quick and tool-free; and disassembly is convenient for cleaning and replacement.

[0034] Preferably, both the lampshade bracket 41 and the lamp panel bracket 3 are circular, and the outer contour of the lampshade bracket 41 matches that of the lamp panel bracket 3. The circular structure distributes stress evenly, which is conducive to rotational installation; the matching outer contour design makes the overall appearance harmonious, seamlessly spliced, and enhances the product's aesthetics and sense of unity.

[0035] Preferably, the lamp holder 3 is made of a one-piece plate structure of metal, and the mounting column 31 is welded to the lamp holder 3. The metal material (such as aluminum alloy or cold-rolled steel plate) provides high-strength support to ensure the weight of the light-emitting element 5 and the entire lamp body is supported; the one-piece structure enhances rigidity and reduces the risk of deformation; the welded connection is firm, reliable, and durable.

[0036] Preferably, the mounting sleeve 21 and the connecting bracket 2 are an integral structure made of plastic. Plastic materials (such as ABS, PC, or PA) have good insulation, corrosion resistance, and processing performance; integral injection molding reduces costs and improves assembly efficiency; the elasticity of plastic helps with fine-tuning and cushioning during the snap-fit ​​process.

[0037] As a preferred option, such as Figure 5 As shown, the strip-shaped mounting holes 11 are evenly distributed along the circumference on the mounting bracket 1. The mounting bracket 1 is provided with a thickened portion 13 extending radially and distributed circumferentially, and the strip-shaped mounting holes 11 are formed on the thickened portion 13. The thickened portion 13 enhances the structural strength of the mounting hole area, preventing tearing or deformation of the hole edge due to excessive fastener tightening force; the even distribution improves the stress balance, ensuring that the mounting bracket 1 does not deform under long-term load.

[0038] As a preferred option, such as Figure 5 As shown, the mounting bracket 1 is provided with a reinforcing plate 14 surrounding each strip-shaped mounting hole 11. The reinforcing plate 14 further enhances the compressive and shear resistance around the mounting hole, making it particularly suitable for fragile supports such as concrete or gypsum board; at the same time, it can guide the second fastener 7 to be accurately aligned, improving installation accuracy.

[0039] Fasteners include common screws, bolts, and studs. The first fastener 6 can be a self-tapping screw, machine screw, or combination screw, and the matching type is selected according to the material of the mounting column 31; the second fastener 7 can be an expansion bolt, self-tapping screw, wood screw, or hanger nut, etc., depending on the material of the support body A, to ensure a reliable connection with the building structure.

[0040] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
