Description

Technical Field

[0001] This utility model belongs to the technical field of tunnel lighting equipment, specifically relating to a modular assembly structure for tunnel lighting fixtures. Background Technology

[0002] Tunnel lighting fixtures are crucial facilities for ensuring driving safety within tunnels. They provide sufficient and uniform illumination, enabling drivers to clearly observe road conditions and obstacles, thereby effectively reducing the probability of traffic accidents. The installation structure of the lighting fixtures is paramount in tunnel lighting systems. Existing tunnel lighting fixture installation structures typically employ a fixed, integrated installation. However, when a fixture malfunctions, the entire fixture must be disassembled for repair or replacement, which is difficult. Therefore, a modular, modular installation structure for tunnel lighting fixtures is urgently needed to address these issues. Utility Model Content

[0003] In view of the problems mentioned above in the background technology, the purpose of this utility model is to provide a modular assembly structure for tunnel lighting fixtures.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A modular assembly structure for a tunnel lighting fixture includes a mounting frame with mounting holes at its four corners. Fixing components are installed within these mounting holes. An assembly base is mounted on the surface of the mounting frame. A power-conducting post is installed at the center of the assembly base, and a lamp holder is connected to the power-conducting post. The lamp holder is mounted on the assembly base, and a reflector is mounted on its surface. An LED is installed inside the reflector. An assembly component is mounted on top of the fixing components. A lamp cover is mounted on the outside of the assembly component, and the lamp cover is mounted on the outside of the reflector. A barrier sleeve is mounted on the bottom of the lamp cover and is slidably disposed on the outside of the assembly base.

[0006] Furthermore, the fixing component includes a fixing rod, the bottom of which has a fixing head, and the outer surface of which is threaded. A locking block is threadedly connected to the fixing rod. This structural design facilitates the fixing and installation of the mounting bracket.

[0007] Further specifying, the mounting base includes a chassis with a circular annular structure. Side plates are mounted on the inner and outer sides of the top of the chassis, and a top plate is mounted on the top of the side plates. A partition is provided between the chassis and the top plate. The top plate and the partition have several evenly arranged limiting grooves. A limiting opening is provided on one side of each limiting groove. An assembly rod is slidably installed within the limiting groove. The top of the assembly rod is fixedly installed on the bottom of the lamp holder, and a limiting block is installed on the bottom of the assembly rod. The shape of the limiting block matches the limiting opening, and the limiting block is slidably disposed between the chassis and the partition. This structural design facilitates the installation of the lamp holder.

[0008] Further specifying, the assembly includes a base, a guide rod mounted on the top of the base, a guide head mounted on the top of the guide rod, a slider slidably mounted on the guide rod, guide ramps on both the upper and lower sides of the slider, a groove matching the slider at the bottom of the guide head, an assembly kit slidably mounted on the outer side of the guide head, the assembly kit being installed on the four sides of the bottom of the lampshade, assembly slots on both sides of the assembly kit, guide seats installed in the assembly slots, a T-shaped limiting rod slidably mounted on the guide seat, a limiting block mounted on the inner side of the T-shaped limiting rod, an inclined surface on the inner side of the limiting block, a spring mounted on the outer side of the limiting block, and the other side of the spring mounted on the guide seat. This structural design facilitates the assembly and disassembly of the lampshade.

[0009] Furthermore, a threaded post is installed at the bottom of the base, and the threaded post is locked inside the fixing rod. This structural design facilitates the fixed installation of the base on the fixing rod.

[0010] The beneficial effects of this utility model are as follows: Unlike the traditional integral fixed installation structure, when a component of the lamp malfunctions, it is not necessary to disassemble the entire lamp. If only the lampshade is damaged, the structural characteristics of the assembly components can be utilized to quickly disassemble and replace the lampshade through simple operations such as pressing and sliding. If the lamp holder is faulty, it can be easily disassembled and installed by rotating the lamp holder. This greatly reduces the difficulty of maintenance and replacement, significantly improves maintenance efficiency, reduces the time of tunnel lighting interruption caused by maintenance, and ensures the safety of tunnel traffic.

Detailed Implementation

[0018] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Example 1, such as Figure 1 , Figure 2 and Figure 3 As shown, a modular assembly structure for a tunnel lighting fixture includes a mounting frame 1, mounting holes 2 at the four corners of the mounting frame 1, fixing components 3 installed in the mounting holes 2, an assembly base 4 mounted on the surface of the mounting frame 1, a power supply post 5 mounted at the center of the assembly base 4, a lamp holder 6 connected to the power supply post 5, the lamp holder 6 mounted on the assembly base 4, a reflector bowl 7 mounted on the surface of the lamp holder 6, an LED bead 8 installed inside the reflector bowl 7, an assembly component 9 mounted on the top of the fixing component 3, a lamp cover 10 mounted on the outside of the assembly component 9, the lamp cover 10 mounted on the outside of the reflector bowl 7, and a barrier sleeve 11 mounted on the bottom of the lamp cover 10, the barrier sleeve 11 being slidably disposed on the outside of the assembly base 4.

[0020] In this embodiment, when installing the tunnel lighting fixture, the fixing component 3 is first driven into the inner wall of the tunnel at a preset position. Then, the mounting bracket 1 is fixed onto the fixing component 3, and the mounting bracket 1 is installed on the fixing component 3 through the mounting hole 2. The mounting bracket 1 is then fixed in the corresponding position in the tunnel. After that, the lamp holder 6 is installed into the assembly base 4, so that the power column 5 supplies power to the lamp holder 6. The reflector bowl 7 and the lamp beads 8 on the lamp holder 6 form the lighting and light-emitting part. Finally, the lamp cover 10 is installed on the outside of the reflector bowl 7 through the assembly component 9. The lamp cover 10 plays a role in protecting the lamp beads 8 and focusing the light. After the lamp cover 10 is installed, the barrier sleeve 11 on the lamp cover 10 is located on the outside of the lamp holder 6, which can prevent dust from entering the lamp holder 6.

[0021] Example 2, as Figure 1 , Figure 2 and Figure 4 As shown, this embodiment adds the following structure based on embodiment 1: the fixing component 3 includes a fixing rod 12, the bottom of the fixing rod 12 is provided with a fixing head 13, the outer surface of the fixing rod 12 is provided with threads, and the fixing rod 12 is connected to a locking block 14 by the threads.

[0022] In this embodiment, during installation, the fixing head 13 at the bottom of the fixing rod 12 is first driven into the mounting surface of the tunnel to fix the fixing rod 12. Then, the mounting bracket 1 is installed on the fixing rod 12 through the mounting holes 2 at the four corners. Finally, the locking block 14 is installed on the outside of the fixing rod 12 and rotated to move on the thread of the fixing rod 12, thereby clamping and fixing the mounting bracket 1 and ensuring the fixed installation of the mounting bracket 1.

[0023] Example 3, as Figure 2 and Figure 3 As shown, this embodiment adds the following structure based on embodiment 1: the mounting base 4 includes a chassis 15, which is arranged in a circular shape. Side plates 16 are installed on the inner and outer sides of the top of the chassis 15, and a top plate 17 is installed on the top of the inner and outer side plates 16. A partition 18 is provided between the chassis 15 and the top plate 17. Several evenly arranged limiting grooves 19 are provided on the top plate 17 and the partition 18. A limiting slot 20 is provided on one side of the limiting groove 19. An assembly rod 21 is slidably installed in the limiting groove 19. The top of the assembly rod 21 is fixedly installed on the bottom of the lamp holder 6. A limiting block 22 is installed on the bottom of the assembly rod 21. The shape of the limiting block 22 matches the limiting slot 20. The limiting block 22 is slidably disposed between the chassis 15 and the partition 18.

[0024] In this embodiment, when installing the lamp holder 6, the assembly rod 21 at the bottom of the lamp holder 6 is aligned with the limiting slot 20 and inserted, so that the assembly rod 21 pushes the limiting block 22 from the limiting slot 20 and is installed. After installation, the limiting block 22 is located between the chassis 15 and the partition 18. Then, the lamp holder 6 is rotated, so that the lamp holder 6 drives the assembly rod 21. The assembly rod 21 drives the limiting block 22 from the limiting slot 20 and slides into the limiting slide groove 19 for installation. By limiting the limiting block 22 through the partition 18, the lamp holder 6 can be prevented from falling off, and the lamp holder 6 can be positioned and installed on the assembly base 4.

[0025] Example 4, as Figure 4 As shown, this embodiment adds the following structure based on embodiment 1: the assembly component 9 includes a base 23, a guide rod 24 is installed on the top of the base 23, a guide head 25 is installed on the top of the guide rod 24, a slider 26 is slidably installed on the guide rod 24, guide inclined surfaces 27 are provided on both the upper and lower sides of the slider 26, a groove 28 matching the slider 26 is provided at the bottom of the guide head 25, an assembly kit 29 is slidably installed on the outer side of the guide head 25, the assembly kit 29 is installed on the four sides of the bottom of the lampshade 10, an assembly groove 30 is provided on both sides of the assembly kit 29, a guide seat 31 is installed in the assembly groove 30, a T-shaped limiting rod 32 is slidably installed on the guide seat 31, a limiting plug 34 is installed on the inner side of the T-shaped limiting rod 32, an inclined surface 35 is provided on the inner side of the limiting plug 34, a spring 36 is installed on the outer side of the limiting plug 34, and the other side of the spring 36 is installed on the guide seat 31.

[0026] In this embodiment, when installing the lampshade 10, first align the mounting piece 29 at the bottom of the lampshade 10 with the guide head 25, then press the lampshade 10 so that the lampshade 10 drives the mounting piece 29 to insert into the guide head 25. During the pressing installation process, the limiting plug 34 slides along the guide head 25 through the inclined surface 35, and under the action of pressure, pushes the T-shaped limiting rod 32 to move outward, and at the same time squeezes the spring 36, so that the limiting plug 34 can be retracted into the assembly groove 30. After the limiting plug 34 passes the guide head 25, the spring 36 loses pressure and rebounds, pushing the limiting plug 34 to be stuck on the lower side of the guide head 25, thus completing the installation of the lampshade 10.

[0027] When removing the lampshade 10, simply press the lampshade 10 again, causing it to move the mounting bracket 29. The mounting bracket 29 then moves the limiting block 34 downwards until it slides along the guide slope 27 of the slider 26 via the inclined surface 35 and retracts into the mounting groove 30. After the limiting block 34 passes the slider 26, the spring 36 rebounds and pushes the limiting block 34 into the lower side of the slider 26. Pulling the lampshade 10 upwards then moves the mounting bracket 29, which in turn moves the limiting block 34. The limiting block 34 then moves the slider 26 upwards along the guide rod 24 until the top of the slider 26 is installed into the groove 28. At this point, the guide slope 27 on the lower side of the slider 26 contacts the outer surface of the guide head 25. The limiting block 34 then slides along the guide slope 27 on the lower side of the slider 26 again. Slide it into the assembly slot 30, and then slide it out from the guide head 25 via the slider 26 to remove the lamp cover 10.

[0028] Example 5, as Figure 4 As shown, this embodiment adds the following structure to the embodiment 4: a threaded post 37 is installed at the bottom of the base 23, and the threaded post 37 is locked inside the fixing rod 12.

[0029] In this embodiment, during installation, the base 23 is rotated to lock the threaded post 37 in the threaded groove inside the fixing rod 12, thereby achieving a locking connection between the base 23 and the fixing rod 12.

[0030] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
