Description

Technical Field

[0001] This utility model belongs to the field of tunnel lighting technology, and in particular relates to a lighting lamp for tunnels that is easy to maintain. Background Technology

[0002] Tunnel lighting is a special lighting equipment designed for enclosed traffic environments such as tunnels and underground passages. Its core function is to ensure driving safety and improve traffic efficiency through scientific lighting and intelligent control. It usually uses high-efficiency LED light sources and has the characteristics of uniform brightness, anti-glare, and strong weather resistance, which can adapt to complex environments such as humidity and exhaust gas corrosion in tunnels.

[0003] Existing tunnel lighting systems designed for easy maintenance often suffer from cumbersome disassembly processes, requiring manual disassembly of complex components, which consumes significant time and manpower, resulting in low maintenance efficiency. Furthermore, after disassembly, space constraints hinder comprehensive maintenance when inspecting, repairing, or replacing internal components. Moreover, reassembly often results in poor sealing performance, failing to effectively prevent the intrusion of external liquids, gases, and other impurities, thus affecting the normal operation and lifespan of the lighting system and failing to meet the demands for efficient maintenance and stable operation of tunnel lighting.

[0004] To address these issues, we provide an easy-to-maintain lighting system for tunnels. Utility Model Content

[0005] The purpose of this invention is to provide a lighting fixture for tunnels that is easy to maintain. By combining a disassembly mechanism and a snap-fit ​​mechanism, it solves the problems of low disassembly and maintenance efficiency, cumbersome operation, insufficient sealing performance, and limited maintenance space in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a maintenance-friendly lighting fixture for tunnels, comprising a mounting plate with a disassembly mechanism at its bottom and a lamp housing slidably connected to its top. The lamp housing has a locking mechanism on its surface. The disassembly mechanism includes a support plate, the top of which is fixedly connected to the mounting plate. An electric telescopic rod is connected through one side of the support plate, and a transmission component is fixedly connected to the output end of the electric telescopic rod. A plug is fixedly connected to the inner wall of the transmission component. A slot is provided on the surface of the lamp housing, and the plug engages with the slot. The locking mechanism includes a lampshade that engages with the lamp housing. A self-locking mechanism is fixedly connected to the surface of the lampshade, and a sealing ring is fixedly connected to the surface of the lamp housing. The top of the sealing ring contacts the inner wall of the lampshade. The electric telescopic rod drives the transmission component, causing the plug to engage or disengage with the lamp housing slot, achieving rapid locking and disassembly of the lamp housing. The lampshade engages with the lamp housing via the self-locking mechanism, and the sealing ring enhances the sealing performance, preventing the entry of humid gases or dust from the tunnel. The rapid disassembly design significantly improves the maintenance efficiency of high-altitude lighting equipment in tunnels, and the double sealing effectively resists corrosion from the harsh tunnel environment, extending the lifespan of the lamp.

[0008] The present invention is further configured such that the self-locking mechanism includes a self-locking tube, one end of which is inserted through the surface of the lampshade, and a self-locking rod is inserted through the inner cavity of the self-locking tube. One end of the self-locking rod is inserted into the inner cavity of the lampshade. A self-locking groove for use with the self-locking rod is formed on the surface of the lampshade. A limiting plate is fitted on the surface of the self-locking rod. A spring is fixedly connected to one side of the limiting plate, and the other end of the spring is fixedly connected to the inner wall of the self-locking tube. A wrench is movably connected to the other end of the self-locking rod through a rotating rod. Rotating the wrench moves the self-locking rod, compressing the spring to unlock the lampshade. The spring releases its elastic potential energy to push the self-locking rod into the self-locking groove of the lampshade, achieving automatic locking. The spring-assisted automatic locking structure ensures the sealing of the lampshade during installation, avoiding the cumbersome operation of traditional bolt fixing. Locking and unlocking can be completed by rotating the wrench 90 degrees. The operation is simple and highly visible, reducing the risk of misoperation by maintenance personnel.

[0009] The present invention is further configured such that a slide rail is fixedly connected to the top of the mounting plate, and a slide groove is provided at the bottom of the lamp housing to cooperate with the slide rail. The slide rail and the slide groove are slidably connected, and the slide rail of the mounting plate and the slide groove of the lamp housing are slidably engaged to provide guidance for the disassembly of the lamp housing, ensuring that the plug and the slot are accurately aligned. The guide structure of the slide rail and the slide groove eliminates lateral deviation during lamp housing installation, allowing the plug to be smoothly inserted into the slot, avoiding jamming or poor sealing caused by inaccurate manual alignment, and improving the smoothness and reliability of maintenance operations.

[0010] The present invention is further configured such that a lamp holder is fixedly connected to the bottom of the inner cavity of the lamp housing, and a uniformly distributed lighting lamp is fixedly connected to the top of the lamp holder. The uniformly distributed lighting lamps inside the lamp housing provide tunnel lighting, the lamp holder fixes the position of the light source, the modular lamp holder design supports the replacement of individual bulbs, and the uniformly distributed multi-light source layout ensures that there are no blind spots in tunnel lighting.

[0011] The present invention is further provided that a handle is fixedly connected to one side of the mounting plate, and the surface of the handle is provided with anti-slip texture. The anti-slip texture on the surface of the handle increases the grip friction, making it easier to pull the lamp housing. The anti-slip handle conforms to the ergonomic design, reduces the risk of slipping when pulling the lamp housing, and improves the safety and convenience of operation.

[0012] The present invention is further configured such that mounting bases are fixedly connected to both sides of the mounting plate, and mounting holes are provided on the top of the mounting bases. The number of mounting holes is eight, and the eight mounting holes on both sides of the mounting bases are used to fix the lamps to the top of the tunnel.

[0013] The present invention is further configured such that the transmission component includes a push plate, the bottom of one side of the push plate is fixedly connected to the electric telescopic rod, and a clamping plate is fixedly connected to the top of one side of the push plate. The inner wall of the clamping plate is fixedly connected to the insert block. The push plate of the transmission component connects the electric telescopic rod and the clamping plate, and the clamping plate fixes the insert block to realize the transmission of force. The split transmission structure facilitates the replacement of parts. The clamping plate design increases the force-bearing area of ​​the insert block, avoids deformation caused by single-point force, extends the service life of the transmission component, and ensures that the driving force of the electric telescopic rod is effectively transmitted to the insert block.

[0014] The present invention is further configured such that a limiting groove is provided on one side of the mounting plate to engage with the lamp housing, and a slot is provided on the other side of the mounting plate to engage with the locking plate. The limiting groove of the mounting plate engages with the lamp housing, and the slot engages with the locking plate, further constraining the horizontal and vertical displacement of the lamp housing. The double locking structure enhances the stability of the lamp housing after installation, especially in the environment of vibration generated by vehicles traveling in tunnels, effectively reducing lamp shaking, avoiding loosening of the plug or detachment of the lamp cover due to vibration, and improving the reliability of the lighting system.

[0015] The present invention has the following beneficial effects.

[0016] 1. The automated design of the linkage transmission component of the electric telescopic pole of this utility model realizes the rapid unlocking of the lamp housing installation state. There is no need to manually disassemble complex parts. Simply start the equipment to make the plug disengage from the slot, which greatly simplifies the disassembly process, significantly improves the maintenance efficiency of tunnel lighting, reduces the intensity of manual operation, and makes maintenance work more convenient and efficient.

[0017] 2. The self-locking release mechanism of this utility model allows for easy removal of the lamp cover, fully exposing the lighting fixture inside the lamp housing. This facilitates comprehensive inspection, repair, or replacement by maintenance personnel. When the lamp cover is reset after maintenance, the squeezing action of the inner wall of the lamp cover on the sealing ring, combined with the locking mechanism, effectively achieves a sealed self-lock between the lamp cover and the lamp housing. This reliably prevents external liquids, gases, and other impurities from entering the inner cavity of the lamp housing. It provides ample operating space for the maintenance of the lighting fixture and ensures that the inside of the lamp housing remains in a stable and sealed environment for a long time, ensuring the continuous normal operation of the lighting fixture.

By holding the pull handle, the lamp housing 3 and its connected structure can be pulled out. The locking of the self-locking mechanism 32 is released, and the lamp cover 31 can be removed. The wrench 326 is pulled outward, and the wrench 326 rotates 90 degrees, causing the self-locking rod 322 to move outward, releasing the locking of the lamp cover 31 to the lamp housing 3. The self-locking rod 322 compresses the spring 325 outward to store elasticity. Potential energy is used to remove the lampshade 31 for cleaning, and to maintain the lighting lamp 8 inside the lamp housing 3. After maintenance, the lampshade 31 is reset, and the inner wall of the lampshade 31 presses against the sealing ring 33, locking the self-locking mechanism 32 again. The wrench 326 is reset by pulling it, and the spring 325 releases elastic potential energy to drive the self-locking rod 322 to move towards the lamp housing 3 and engage in the self-locking groove 323, sealing and locking the lampshade 31 and the lamp housing 3 to prevent external liquids, gases and other impurities from entering the inner cavity of the lamp housing 3, ensuring the sealing environment and normal operation of the lamp housing 3.
