Description

Technical Field

[0001] This utility model relates to the field of tunnel lighting technology, and in particular to a tunnel lighting device. Background Technology

[0002] Tunnel lighting systems are lighting devices specifically designed for use inside tunnels. Their purpose is to improve lighting conditions within tunnels, ensure driving safety, and enhance the driving experience. Tunnel lighting systems typically include different types of lamps and control systems to meet the lighting needs of different areas within the tunnel. Tunnel lighting can improve road conditions within the tunnel, enhance visual comfort, reduce driver fatigue, and ultimately improve tunnel capacity and traffic safety.

[0003] Existing tunnel lighting devices may include those designed for easy installation and disassembly, and some lamps may employ modular designs to make it easier to replace bulbs or the entire lamp. The installation structure of the tunnel lighting lamps also affects their ease of installation and disassembly. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a tunnel lighting device.

[0005] This utility model is achieved by the following technical solution: a tunnel lighting device, including a lampshade housing, a connecting screw is threadedly connected to the inside of the lampshade housing, a limit block is threadedly connected to the surface of the connecting screw, and a connecting bracket is fixedly connected to the surface of the limit block;

[0006] A support column is fixedly connected to the top of the connecting bracket, and a fixed top plate is fixedly connected to the top of the support column. An expansion bolt is threaded into the fixed top plate. A positioning groove is provided inside the limiting block. An extension slide rod is fixedly connected to the inside of the connecting bracket. A sliding sleeve is slidably connected to the surface of the extension slide rod. A push plate is fixedly connected to the top of the sliding sleeve. A limiting plate is fixedly connected to the top of the sliding sleeve. A lighting lamp is fixedly connected to the bottom of the lampshade housing.

[0007] With the above technical solution, the four connecting screws are symmetrically distributed around the lampshade housing, with each pair forming a group. This makes the connection between the lampshade housing and other components more stable. During installation and use, when affected by external factors, the symmetrically distributed connecting screws can distribute the force evenly, reduce local stress concentration, and prevent the lampshade housing from loosening or deforming, thereby ensuring the stability of the lighting device.

[0008] As a further improvement to the above solution, the number of connecting screws is set to four, with two screws forming a group, and the four connecting screws are symmetrically distributed on the left and right sides with the lampshade shell as the center.

[0009] As a further improvement to the above solution, the connecting screw extends through the limiting block into the interior of the lampshade housing, and the bottom of the connecting bracket contacts the top surface of the lampshade housing.

[0010] As a further improvement to the above solution, the number of the limiting block and the positioning slide is set to two, and the two limiting blocks and the positioning slide are symmetrically distributed on the left and right sides with the lampshade shell as the center.

[0011] Through the above technical solution, the connecting screw extends through the limiting block into the interior of the lampshade housing. This connection method tightly fixes the limiting block to the lampshade housing, enhancing the overall integrity of the structure. At the same time, the bottom of the connecting bracket contacts the top surface of the lampshade housing, providing additional support for the lampshade housing and helping to distribute the weight borne by the lampshade housing. Especially considering that the lighting device may be used for a long time in special environments such as tunnels, this structure can effectively extend the service life of the device.

[0012] As a further improvement to the above solution, the expansion bolt is located at the top of the lampshade housing and at the top of the connecting bracket.

[0013] As a further improvement to the above solution, the sliding sleeve is inserted into the positioning groove and the limiting block, and the number of the push plate and the limiting plate is set to two, with the two push plates and the limiting plate symmetrically distributed on the left and right sides with the lampshade shell as the center.

[0014] As a further improvement to the above solution, the limiting plate is inserted into the surface of the limiting block, and the extension slide is located at the top of the lampshade housing.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention features two push plates and a limiting plate symmetrically distributed around the lampshade housing. When adjusting the device, the symmetrically distributed push plates and limiting plates ensure that the operating force is evenly applied to the device. When the push plates are pushed, the simultaneous action of the push plates on both sides smoothly drives the sliding sleeve to slide on the extension rod, making the adjustment of the lighting device more stable and precise. The limiting plate is inserted into the surface of the limiting block. This insertion method, combined with the symmetrical structure, helps to further fix the position of the sliding sleeve, preventing it from sliding unexpectedly when not in operation and ensuring the stability of the lighting device.

[0017] This invention features an extension slide rod located at the top of the lampshade housing, providing precise guidance for the sliding sleeve. During use, the sliding sleeve slides along the extension slide rod, ensuring accurate movement trajectories of related components and enabling precise adjustment of the lighting device. The extension slide rod also provides support for the entire structure, enhancing its overall strength. The expansion bolts are located at the top of the lampshade housing and the top of the connecting bracket. This layout facilitates the secure installation of the entire lighting device in a suitable position on the tunnel ceiling. The expansion bolts ensure that the lighting device will not easily shake or fall off in the special environment of a tunnel. The reasonable placement also makes full use of space and avoids mutual interference between components. Attached Figure Description

When adjusting the device, the symmetrically distributed push plates 11 and limit plates 12 can make the operating force evenly applied to the device. When the push plates 11 are pushed, the push plates 11 on both sides act simultaneously, which can smoothly drive the sliding sleeve 10 to slide on the extension slide rod 8, so that the adjustment of the lighting device is more stable and precise.
