Description

Technical Field

[0001] This utility model relates to the technical field of road traffic safety facilities, and more specifically, to a tunnel self-illuminating reflective ring. Background Technology

[0002] As an important part of road traffic, tunnels have significantly different lighting environments compared to open roads. When entering a tunnel, vehicles quickly switch from a bright natural environment to a relatively dark enclosed space, which can cause drivers to experience the "black hole effect." When exiting a tunnel, the sudden increase in light can cause the "white hole effect." Both of these situations can lead to difficulties in visual adaptation for drivers and a decrease in reaction speed.

[0003] Existing tunnel reflective devices suffer from problems such as inconvenient installation and disassembly, poor structural stability, and are prone to detachment or damage after long-term exposure to vehicle exhaust corrosion and airflow impact, resulting in high maintenance costs. Furthermore, traditional reflective materials have a short luminous duration, making it difficult to provide clear warning signs for extended periods in dark environments.

[0004] To address the aforementioned issues, a tunnel self-luminous reflective ring is proposed. Utility Model Content

[0005] To solve the above technical problems, a tunnel self-luminous reflective ring is provided.

[0006] To achieve the above objectives, the present invention can be implemented using the following technical solutions: This utility model provides a tunnel self-illuminating reflective ring, comprising: an arc-shaped base plate, on one side of which a plurality of evenly distributed mounting slots are formed; a mounting box is detachably mounted on the outer periphery of the mounting slots; cavities are formed inside all four sides of the mounting box; connecting rods are symmetrically mounted on the inner walls of the cavities; a return spring is sleeved on the outer periphery of the connecting rods; a lever is slidably connected to the outer periphery of the connecting rods; sliding grooves are formed on all four sides of the mounting box; a limiting plate is fixedly mounted on the bottom of the lever; the lever abuts against one side of the return spring; a slot is formed in the inner wall of the mounting slots; and the limiting plate is inserted into the slot in the inner wall of the mounting slots.

[0007] Preferably, an LED light is installed inside the mounting box, a protective plate is detachably installed on the surface of the mounting box, an indicator is installed on the surface of the protective plate, and screws are threaded around the protective plate.

[0008] Preferably, a plurality of evenly distributed mounting strips are fixedly mounted on the side of the arc-shaped substrate near the mounting groove, and a plurality of evenly distributed adhesive pads are mounted on the surface of the mounting strips, and reflective strips are adhered to the mounting strips through the adhesive pads.

[0009] Preferably, a mounting plate is fixedly mounted on the top of the arc-shaped substrate, and the top of the mounting plate has a plurality of evenly distributed mounting holes, and expansion bolts are mounted on the surface of the mounting holes.

[0010] Preferably, the arc-shaped substrate is made of aluminum alloy, and the reflective strip is made of long afterglow luminescent material.

[0011] As described above, the features and advantages of the tunnel self-luminous reflective ring of this utility model are: The device combines active light emission and passive reflection. The LED lights provide continuous active illumination, and the reflective strips made of long-afterglow luminous material can still emit light for a long time when there is no power supply. Even in the event of a sudden power outage or circuit failure, the tunnel outline and direction of travel can be clearly marked, effectively alleviating the visual discomfort caused by the "black hole effect" and "white hole effect" and reducing the risk of traffic accidents.

[0012] The mounting box, through the cooperation of a lever, a limiting insert, and a return spring, can be quickly and securely engaged with the mounting slot of the curved substrate. Disassembly is simple; just move the lever to remove it, without the need for complicated tools. The protective plate is detachably connected with screws, facilitating the inspection and replacement of LED lights. Meanwhile, the curved substrate is securely installed using the mounting holes on the mounting plate and expansion bolts. The reflective strip is fixed with adhesive pads, resulting in high assembly efficiency and saving time and effort in subsequent maintenance.

[0013] The curved base plate is made of aluminum alloy, which is high in strength, corrosion-resistant, and lightweight. It can withstand the erosion of vehicle exhaust and the impact of airflow in tunnels and is not easily deformed or damaged. The protective plate can effectively protect the LED lights and indicators, prevent dust and debris from accumulating and affecting the performance, extend the overall service life of the device, and reduce the maintenance costs caused by frequent replacements.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] See Figures 1-5 As shown, this is an embodiment of the present invention, and the provided tunnel self-luminous reflective ring will be described in detail below: A tunnel self-luminous reflective ring, such as Figures 1-5 As shown, it includes: an arc-shaped base plate 1, with multiple evenly distributed mounting grooves 2 on one side of the arc-shaped base plate 1; a mounting box 15 is detachably mounted on the outer periphery of the mounting grooves 2; cavities are formed inside all four sides of the mounting box 15; connecting rods 14 are symmetrically mounted on the inner walls of the cavities; a return spring 13 is sleeved on the outer periphery of the connecting rods 14; a lever 11 is slidably connected to the outer periphery of the connecting rods 14; sliding grooves 9 are formed on all four sides of the mounting box 15; a limit plate 12 is fixedly mounted on the bottom of the lever 11; the lever 11 abuts against one side of the return spring 13; and the inner walls of the mounting grooves 2 are... The mounting box 15 is provided with a slot. The limiting insert plate 12 is inserted into the slot on the inner wall of the mounting groove 2. When the mounting box 15 is installed, the lever plate 11 is moved along the sliding groove 9 on the surface of the mounting box 15. The lever plate 11 slides along the connecting rod 14 and compresses the return spring 13, which drives the limiting insert plates 12 located on the same connecting rod 14 to move closer to each other. After the mounting box 15 is aligned with the mounting groove 2 and placed in, the lever plate 11 is released. The return spring 13 rebounds and pushes the lever plate 11 to return to its original position, so that the limiting insert plate 12 is inserted into the slot on the inner wall of the mounting groove 2, thus completing the snap-fit ​​fixing of the mounting box 15 and the arc-shaped base plate 1.

[0017] Furthermore, such as Figures 1-5As shown, an LED light 10 is installed inside the mounting box 15. A protective plate 18 is detachably installed on the surface of the mounting box 15. An indicator 17 is installed on the surface of the protective plate 18. Screws 16 are threaded around the protective plate 18. Multiple evenly distributed mounting strips 3 are fixedly installed on the side of the arc-shaped base plate 1 near the mounting groove 2. Multiple evenly distributed adhesive pads 7 are installed on the surface of the mounting strips 3. Reflective strips 4 are attached to the mounting strips 3 through the adhesive pads 7. The protective plate 18 is threaded to the mounting box 15 through the screws 16 around its perimeter, thus encapsulating and protecting the LED light 10 inside the mounting box 15. When the device is powered on, the LED light 10 inside the mounting box 15 starts to emit light, and the light penetrates the protective plate 18 and shines outward, providing active lighting warning for the tunnel interior. At the same time, the indicator 17 on the surface of the protective plate 18 is clearly visible under the light of the LED light 10, guiding the driver to clearly understand the direction of travel in the tunnel, effectively alleviating the visual adaptation problems caused by the "black hole effect" and "white hole effect" at the tunnel entrance and exit.

[0018] Furthermore, an mounting plate 8 is fixedly installed on the top of the arc-shaped substrate 1. The top of the mounting plate 8 has multiple evenly distributed mounting holes 5, and expansion bolts 6 are installed on the surface of the mounting holes 5. The arc-shaped substrate 1 is made of aluminum alloy, and the reflective strip 4 is made of long-afterglow luminous material. Through the mounting holes 5 on the top mounting plate 8 of the arc-shaped substrate 1 and the expansion bolts 6, the arc-shaped substrate 1 is stably fixed at a designated position on the inner wall of the tunnel. The reflective strip 4 is made of long-afterglow luminous material. When the tunnel is under normal lighting or the LED light 10 is working, it can absorb and store light energy from the environment. When a sudden power outage or circuit failure causes the LED light 10 to fail, the reflective strip 4 will slowly release the stored light energy to achieve long-term self-luminescence, continuously marking the tunnel outline and travel path where the arc-shaped substrate 1 is located, ensuring the safety of vehicle passage in emergency situations.

[0019] Specifically, the arc-shaped base plate 1 is securely fixed to a designated position on the inner wall of the tunnel by using the mounting holes 5 on the top mounting plate 8 of the arc-shaped base plate 1 and the expansion bolts 6; the reflective strip 4 is quickly bonded and fixed by the adhesive pads 7 on the surface of the mounting strip 3 on the side of the arc-shaped base plate 1; when installing the mounting box 15, the lever 11 is moved along the sliding groove 9 on the surface of the mounting box 15, the lever 11 slides along the connecting rod 14 and compresses the return spring 13, causing the limiting insert 12 to retract, the mounting box 15 is aligned with the mounting groove 2 and then the lever 11 is released, the return spring 13 rebounds and pushes the lever 11 to return, so that the limiting insert 12 is inserted into the mounting groove 2. The slots on the inner wall secure the mounting box 15 to the arc-shaped base plate 1. The protective plate 18 is threadedly connected to the mounting box 15 via screws 16 around its perimeter, thus encapsulating and protecting the LED lights 10 inside the mounting box 15. When the device is powered on, the LED lights 10 inside the mounting box 15 activate and emit light, which penetrates the protective plate 18 and shines outward, providing active lighting warnings inside the tunnel. Simultaneously, the indicator marks 17 on the surface of the protective plate 18 are clearly visible under the illumination of the LED lights 10, guiding the driver to determine the direction of travel within the tunnel and effectively mitigating the "black hole effect" and "white hole effect" at tunnel entrances and exits. To address the visual adaptation issues, the reflective strip 4 uses a long-afterglow luminous material. During daily tunnel lighting or when the LED light 10 is working, it can absorb and store ambient light energy. When a sudden power outage or circuit failure causes the LED light 10 to malfunction, the reflective strip 4 will slowly release the stored light energy, achieving long-term self-illumination and continuously marking the tunnel outline and travel path where the arc-shaped substrate 1 is located, ensuring vehicle passage safety in emergency situations. When it is necessary to repair or replace the LED light 10, use tools to unscrew the screws 16 around the protective plate 18 to remove the protective plate 18 and operate the LED light 10. If it is necessary to disassemble the mounting box 15, move the lever 11 along the slide groove 9. The lever 11 compresses the reset spring 13 and drives the limit plate 12 to disengage from the slot on the inner wall of the mounting groove 2. At this time, the mounting box 15 can be removed from the mounting groove 2. After maintenance or replacement, reverse the installation and fixing principle to reset the device.

[0020] The above description is merely an embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
