Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to sheet metal support and connection structures used in LED lighting fixtures. Background Technology

[0002] LED lighting fixtures are lighting devices that use light-emitting diodes (LEDs) as their light source. Compared to traditional incandescent and fluorescent lamps, LED lighting fixtures have higher energy efficiency, longer lifespan, and are more environmentally friendly. First, LED lighting fixtures have a very high energy efficiency ratio. Traditional incandescent lamps consume a large amount of electrical energy during the emission process, with most of this energy wasted as heat, and only a small portion converted into light energy. LED lighting fixtures, on the other hand, generate almost no heat when emitting light, and their energy conversion efficiency is far higher than that of traditional lamps, thus saving a significant amount of energy. Second, LED lighting fixtures also have a very long lifespan. Traditional incandescent lamps typically only last for a few thousand hours, while LED lighting fixtures can last for tens of thousands of hours or even longer. This not only reduces the frequency of lamp replacement but also lowers maintenance costs. Furthermore, LED lighting fixtures are environmentally friendly. Traditional fluorescent lamps contain harmful substances such as mercury, which pose potential hazards to the environment and human health. LED lighting fixtures do not contain these harmful substances and do not pollute the environment after disposal. In terms of usage, LED lighting fixtures also have many advantages. They can reach full brightness in a very short time without preheating; and they can be designed in various shapes and sizes to meet different lighting needs. Furthermore, LED lights offer a rich variety of colors and can achieve different brightness and color temperatures through dimming control, creating a comfortable lighting environment for users. In short, as a new type of lighting technology, LED lights are not only energy-saving, durable, and environmentally friendly, but also multifunctional, representing the future trend of the lighting industry.

[0003] Currently, LED lighting fixtures typically use threaded connections for connection. However, threaded connections pose a risk of loosening during use. As lighting fixtures may be subjected to external forces such as vibration and thermal expansion during operation, threaded connections may gradually loosen, leading to insecure fixture components and potentially causing safety issues. Therefore, this approach does not meet current requirements. To address this, we propose a sheet metal support and connection structure for use within LED lighting fixtures. Utility Model Content

[0004] This utility model provides a sheet metal support and connection structure for use in LED lighting fixtures, which enhances the stability and safety of the fixtures and reduces safety hazards caused by loosening. It addresses the issue mentioned in the background section that the connection mechanism of LED lighting fixtures is generally a threaded connection, which carries the risk of loosening during use. Because lighting fixtures may be subjected to external forces such as vibration and thermal expansion during use, the threaded connections may gradually loosen, leading to insecure fixing of lighting fixture components and potentially causing safety issues.

[0005] This utility model provides the following technical solution: a sheet metal support and connection structure used in LED lamps, including a fixing plate and a mounting plate. The mounting plate is disposed on the side of the fixing plate. A first mounting groove is opened on the side of the fixing plate, and a second mounting groove is opened on the side of the mounting plate. Clamping posts are installed inside the first mounting groove and the second mounting groove.

[0006] As an optional solution for the sheet metal support and connection structure used in the LED lamp described in this utility model, the first mounting groove is configured as a cylindrical groove, and a first limiting groove is provided on the side of the first mounting groove.

[0007] As an optional solution for the sheet metal support and connection structure used in the LED lamp described in this utility model, the second mounting groove is configured as a cylindrical groove, a second limiting groove is connected to the side of the second mounting groove, and a sliding groove is connected to the side of the second limiting groove.

[0008] As an optional solution for the sheet metal support and connection structure used in the LED lamp described in this utility model, wherein: the clamping column is provided with a locking component, which is used in conjunction with the first mounting groove and the second mounting groove.

[0009] As an optional solution for the sheet metal support and connection structure used in the LED lamp described in this utility model, the locking assembly includes a fixing plate and a limiting block. The fixing plate is sleeved on the outside of the locking post, and the limiting block is connected to the side of the locking post.

[0010] As an optional solution for the sheet metal support and connection structure used in the LED lamp described in this utility model, the limiting block is slidably engaged with the first limiting groove and the second limiting groove.

[0011] As an optional solution for the sheet metal support and connection structure used in the LED lamp described in this utility model, wherein: the end of the clamping column is connected to a rotating block, and the rotating block is set as a rectangular block.

[0012] As an optional solution for the sheet metal support and connection structure used in the LED lamp described in this utility model, the fixed plate has an installation cavity inside, a piston plate is slidably connected inside the installation cavity, the clamping post passes through the side of the piston plate, a return spring is provided inside the installation cavity, and the return spring is sleeved on the outside of the clamping post.

[0013] This utility model has the following beneficial effects:

[0014] 1. The sheet metal support and connection structure used in this LED lamp uses a fixed plate to engage the locking post inside the first and second mounting slots. The limiting block slides into the first and second limiting slots. Pressing and rotating the rotating block compresses the locking post and the return spring inside the mounting cavity, causing the locking block to engage with the sliding groove. Through the engagement of the locking post and the mounting slots, and the sliding engagement of the limiting block and the limiting grooves, loosening due to vibration or external forces is avoided. This design greatly enhances the stability and safety of the lamp, reduces safety hazards caused by loosening, and solves the problem that LED lamp connections are generally threaded connections, which carry the risk of loosening during use. Because the lamp may be subjected to vibration, thermal expansion, and other external forces during use, the threaded connections may gradually loosen, leading to insecure fixing of lamp components and potentially causing safety issues.

[0015] 2. The sheet metal support and connection structure used in this LED lamp utilizes a piston disc. The piston disc engages with the mounting cavity, and while compressing the return spring and pressing the locking pin, the piston disc slides within the mounting cavity. This sliding motion ensures that the locking pin receives even force, guaranteeing a secure engagement in the first and second mounting slots. This even force distribution reduces the risk of loosening due to localized stress concentration. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: This example aims to address the common problem that LED lighting fixtures typically use threaded connections for their connection mechanisms. However, threaded connections pose a risk of loosening during use. Because lighting fixtures may be subjected to external forces such as vibration and thermal expansion during operation, the threaded connections may gradually loosen, leading to insecure fixture components and potentially causing safety issues. Please refer to [link to relevant documentation]. Figure 1-6 The sheet metal support and connection structure used in the LED lamp includes a fixing plate 110 and a mounting plate 130. The mounting plate 130 is located on the side of the fixing plate 110. A first mounting groove 140 is provided on the side of the fixing plate 110, and a second mounting groove 150 is provided on the side of the mounting plate 130. Clamping posts 111 are installed inside the first mounting groove 140 and the second mounting groove 150.

[0025] The first mounting groove 140 is a cylindrical groove, and a first limiting groove 151 is provided on the side of the first mounting groove 140. The second mounting groove 150 is a cylindrical groove, and a second limiting groove 152 is provided on the side of the second mounting groove 150, and a sliding groove 153 is provided on the side of the second limiting groove 152. A locking assembly 160 is provided inside the locking post 111, and the locking assembly 160 is used in conjunction with the first mounting groove 140 and the second mounting groove 150. The locking assembly 160 includes a fixing plate 161 and a limiting block 162. The fixing plate 161 is sleeved on the outside of the locking post 111, and the limiting block 162 is connected to the side of the locking post 111.

[0026] In this embodiment: The fixing plate 161 engages the locking pin 111 within the first mounting groove 140 and the second mounting groove 150. The limiting block 162 slidably engages with the first limiting groove 151 and the second limiting groove 152. Pressing and rotating the rotating block 163 causes it to compress the locking pin 111 and the return spring 170 inside the mounting cavity 164, thus engaging the locking block with the sliding groove 153. Through the engagement of the locking pin 111 with the mounting groove and the sliding engagement of the limiting block 162 with the limiting groove, loosening due to vibration or external force is avoided. This design greatly enhances the stability and safety of the lamp, reduces safety hazards caused by loosening, and solves the problem that LED lamp connections are generally threaded connections, which carry the risk of loosening during use. Because the lamp may be subjected to vibration, thermal expansion, and other external forces during use, the threaded connection may gradually loosen, leading to insecure fixing of lamp components and potentially causing safety issues.

[0027] Example 2 aims to address the issue of unstable installation. This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 1-6 The limiting block 162 is slidably engaged with the first limiting groove 151 and the second limiting groove 152. A rotating block 163, which is rectangular, is connected to the end of the clamping post 111. An installation cavity 164 is provided inside the fixed disk 161, and a piston disk 165 is slidably connected inside the installation cavity 164. The clamping post 111 passes through the side of the piston disk 165. A return spring 170 is provided inside the installation cavity 164 and is sleeved on the outside of the clamping post 111.

[0028] In this embodiment, the piston disc 165, which cooperates with the mounting cavity 164, slides within the mounting cavity 164 while compressing the return spring 170 and pressing the locking pin 111. This sliding motion ensures that the locking pin 111 is evenly stressed, guaranteeing a secure engagement in the first mounting groove 140 and the second mounting groove 150. This even stress distribution reduces the risk of loosening due to localized stress concentration.
