Description

Technical Field

[0001] This utility model relates to the field of subway tunnel light installation technology, and in particular to a tunnel light installation structure with protective function. Background Technology

[0002] As the core equipment for tunnel lighting, tunnel lights directly affect the safety and comfort of tunnel passage through their performance and installation. In long tunnels with unique environments, tunnel lights need to work continuously and stably to provide sufficient and uniform lighting.

[0003] In the field of subway tunnel lighting, the installation structure of tunnel lights has a crucial impact on their lighting effect, safety, and service life.

[0004] While existing tunnel light installation structures achieve both installation and angle adjustment, they often employ a single adjustment mechanism. This leads to uneven stress on the tunnel light during adjustment, causing it to wobble and resulting in inaccurate angle adjustments. Furthermore, once the angle is fixed, poorly designed fixing structures can loosen and shift, affecting lighting stability. In terms of installation and protection, existing methods are relatively simple and lack flexibility for multi-unit splicing installations based on tunnel length and other practical needs, resulting in poor adaptability. Additionally, the tunnel environment experiences continuous vibrations, and existing structures lack effective shock absorption measures. Prolonged vibrations can damage tunnel light components and shorten their lifespan. Moreover, most installation structures lack reliable fall protection devices, making it highly susceptible to accidents and posing significant safety hazards should a tunnel light detach. Therefore, this paper proposes a tunnel light installation structure with protective functions to address these issues. Utility Model Content

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.

[0036] Reference Figures 1-3This utility model provides an embodiment of a tunnel light installation structure with protective function, including a tunnel light body 1. An adjustment component 2 is provided on the upper surface of the tunnel light body 1. The adjustment component 2 is used to flexibly adjust the illumination angle of the tunnel light body 1 to adapt to the lighting needs of different areas within the tunnel. The adjustment component 2 includes two adjustment seats 21, which are mirror images of each other along the central axis of the tunnel light body 1. The symmetrical arrangement of the adjustment seats 21 ensures that the tunnel light body 1 is subjected to balanced force, guaranteeing stability and preventing tilting during angle adjustment. The bottom of the adjusting seat 21 is fixedly connected to the upper surface of the tunnel light body 1. This fixed connection ensures the structural strength between the adjusting seat 21 and the tunnel light body 1, providing a stable foundation for angle adjustment. Angle adjustment holes 22 are provided on the inner wall of the adjusting seat 21. Multiple angle adjustment holes 22 are evenly distributed in a ring, providing multiple angle selections for the tunnel light body 1 to meet precise control of different lighting angles. The telescopic end of the telescopic pin 25 is movably engaged with the inner wall of the angle adjustment hole 22, and the outer wall of the telescopic end of the telescopic pin 25 is adapted to the size of the inner wall of the angle adjustment hole 22. This size adaptation ensures the telescopic... The tight engagement of the retractable locking pin 25 with the angle adjustment hole 22 prevents loosening or shaking after angle adjustment. A locking hole 23 is provided on the outer wall of the adjustment seat 21, providing space for the installation and positioning of the connecting frame 24. The connecting frame 24 is movably engaged between the inner sides of the adjustment seat 21 and the locking hole 23. As the core connecting component of the adjustment assembly 2, the connecting frame 24 connects the adjustment seat 21 to other components. A telescopic locking pin 25 is fixedly connected to the inner wall of the connecting frame 24. The telescopic locking pin 25 can engage with different angle adjustment holes 22 through telescopic movement, thus quickly completing angle adjustment. A connecting screw 2 is fixedly connected to the outer wall of the connecting frame 24. 6. The connecting frame 24 has a U-shaped frame structure. The U-shaped frame structure of the connecting frame 24 can stably connect to the adjusting seat 21 and improve the overall connection stability. There are two connecting screws 26. The two connecting screws 26 are mirrored along the central axis of the connecting frame 24, and the outer sides of the two connecting screws 26 are attached to the inner wall of the locking hole 23. The symmetrical arrangement of the two screws can evenly distribute the locking force and prevent the connecting frame 24 from shifting during the locking process. The end of the connecting screw 26 is threaded with a locking nut 27. The locking nut 27 can firmly lock the connecting frame 24 and the adjusting seat 21 by engaging with the thread of the connecting screw 26, ensuring that there will be no loosening after the angle is adjusted.

[0037] Reference Figure 1 , Figure 2 and Figure 4The upper surface of the adjusting component 2 is provided with a vibration damping mounting component 3. The vibration damping mounting component 3 can effectively mitigate the impact of tunnel vibration on the tunnel light body 1, while achieving a stable connection with the tunnel roof. The vibration damping mounting component 3 includes a mounting base 31, a connecting base 36, and a second hanging ring 311. These components cooperate with each other to achieve vibration damping, installation, and protection functions. The connecting base 36 is fixedly connected to the upper surface of the connecting frame 24. The connecting base 36 serves as a connecting bridge between the vibration damping mounting component 3 and the adjusting component 2, ensuring effective force transmission. A connecting plate 32 is fixedly connected to the outer side of the mounting base 31. The connecting plate 32 expands the connection range of the mounting base 31, facilitating connection with the installation structure on the tunnel roof. One end of the connecting plate 32 is fixedly connected to a splicing clip 33, which cooperates with the splicing bracket 34 to realize the splicing combination of multiple mounting bases 31, adapting to the installation requirements of tunnels of different lengths. The other end of the connecting plate 32 is fixedly connected to the splicing bracket 34. The outer wall of the splicing clip 33 and the inner wall of the splicing bracket 34 are matched in size. Both the splicing clip 33 and the splicing bracket 34 have assembly holes on their upper surfaces. The size of the assembly holes is adapted to the bolt assembly installation. The size adaptation ensures tight splicing. The assembly holes are used to firmly fix the spliced ​​components through the bolt assembly, improving the stability of the overall structure. The bottom end of the mounting base 31 is fixedly connected to a fixing base 35, which provides the installation base for the buffer component. To ensure the stability of the buffer structure, a buffer rod 37 is movably engaged between the fixed seat 35 and the connecting seat 36. The buffer rod 37 restricts the relative displacement direction between the fixed seat 35 and the connecting seat 36, preventing lateral swaying. A buffer spring 38 is sleeved on the outer side of the buffer rod 37. The buffer spring 38 absorbs vibration energy through its own elastic deformation, playing a damping role. Multiple buffer rods 37 and buffer springs 38 are provided. The top ends of multiple buffer springs 38 are attached to the lower surface of the fixed seat 35, and the bottom ends of multiple buffer springs 38 are attached to the upper surface of the connecting seat 36. The multiple sets of buffer rods 37 and buffer springs 38 work together to distribute the force, improve the overall damping effect, and prevent excessive force on a single point from causing damage to the components. In case of damage, the lower surface of the connecting plate 32 is fixedly connected to the first hanging ring 39, and the bottom end of the second hanging ring 311 is fixedly connected to the upper surface of the tunnel light body 1. The first hanging ring 39 and the second hanging ring 311 provide the upper and lower connection points for the anti-fall chain 310, respectively. The anti-fall chain 310 is fixedly hung between the first hanging ring 39 and the second hanging ring 311. The anti-fall chain 310 can play a bottom protection role when the tunnel light body 1 is accidentally detached, preventing it from falling and causing safety accidents. There are two of each of the first hanging ring 39 and the second hanging ring 311, and the two first hanging rings 39 and the two second hanging rings 311 are set one-to-one. The double sets of hanging rings and chains work together to improve the reliability of the anti-fall protection and avoid the loss of protection when a single chain breaks.

[0038] Working principle: When using this protective tunnel light installation structure, it first achieves fixed installation with the tunnel top through the shock-absorbing installation component 3: by using the matching snap-fit ​​of the splicing clip 33 on the connecting plate 32 and the splicing clip 34, multiple mounting bases 31 can be spliced ​​and combined according to actual needs. Then, the multiple tunnel light bodies 1 are stably connected by the assembly holes and bolt components. Finally, the mounting bases 31 are fixed to the tunnel wall using expansion bolts. After installation is completed;

[0039] Adjustment component 2 can flexibly adjust the illumination angle of the tunnel light body 1: First, loosen the locking nut 27 so that the connecting frame 24 can rotate relative to the adjusting seat 21. At this time, the telescopic pin 25 disengages from the current angle adjustment hole 22. Rotate the tunnel light body 1 to the required angle so that the telescopic pin 25 engages with the corresponding angle adjustment hole 22. Then, tighten the locking nut 27 so that the connecting screw 26 is fixed in the locking hole 23. The angle is fixed by the firm locking of the connecting frame 24 and the adjusting seat 21. The symmetrical arrangement of the two adjusting seats 21 ensures the stability and balanced force during the angle adjustment process. When vibration occurs in the tunnel, the shock-absorbing installation group... The buffer rod 37 and buffer spring 38 in component 3 work together. The buffer spring 38 absorbs vibration energy through its own elastic deformation, while the buffer rod 37 restricts the relative displacement direction of the fixed seat 35 and the connecting seat 36, effectively mitigating the impact of vibration on the tunnel light body 1. At the same time, the anti-fall chain 310, through the connection of the first hanging ring 39 and the second hanging ring 311, plays a bottom protection role when the tunnel light body 1 is at risk of accidental detachment. The cooperation of the double hanging rings and the chain further improves the reliability of the protection, ensuring that the entire structure has good shock absorption performance and safety protection capabilities while achieving flexible adjustment and stable installation.
