[0036] Please see the appendix Figure 1-6This utility model provides an adjustable lighting structure in one embodiment, comprising two lighting units arranged opposite each other along the extension direction of a bridge guardrail 40, the two lighting units being respectively installed at both ends of the bridge guardrail 40. First, it should be noted that, unlike existing technologies that typically install vertical light strips at intervals along the bridge guardrail 40 to enhance its aesthetics, these light strips usually have fixed angles, making them difficult to adjust flexibly according to the usage environment. Furthermore, the fixed-angle light strips may emit light that directly shines into the eyes of pedestrians or drivers, causing interference. This application addresses the aforementioned deficiencies in the prior art by providing an adjustable lighting structure and a bridge guardrail 40. Specifically:

[0037] Each lighting unit includes a fixed component 10, a movable component 20, and a lighting component 30; wherein, the fixed component 10 is detachably connected to the bridge guardrail 40; the movable component 20 includes a movable seat 210, a movable frame 220, and a slide 230, the movable seat 210 is connected to the fixed component 10 and is rotatably disposed, one end of the movable frame 220 is connected to the movable seat 210, and the slide 230 is connected to the movable frame 220 and is movably disposed along the extending direction of the movable frame 220; both ends of the lighting component 30 are connected to the slide 230 and are rotatably disposed.

[0038] Specifically, the adjustable lighting structure in this application includes two lighting units arranged opposite each other along the extension direction of the bridge guardrail 40. The two lighting units are arranged to uniformly illuminate the entire area of ​​the bridge guardrail 40. Each lighting unit includes a fixed component 10, a movable component 20, and a lighting component 30. The fixed component 10 is used to fix the entire structure to the bridge guardrail 40, and its detachable connection facilitates later maintenance and replacement. The movable component 20 is used to adjust the illumination position of the entire lighting unit, and specifically includes a movable base 210, a movable frame 220, and a sliding base 230. The movable seat 210 facilitates the hinge connection between the movable frame 220 and the fixed component 10, thereby enabling the other end of the movable frame 220 to swing around the movable seat 210 to adjust the position of the entire movable frame 220. The movable frame 220 is used for mounting the slide 230, which is used for mounting the lighting component 30. Thus, when the movable frame 220 is rotated to a vertical arrangement, it can illuminate the vertical support part of the bridge guardrail 40, achieving both aesthetic and warning effects. When the movable frame 220 is rotated to a horizontal arrangement, it can illuminate the road surface, facilitating pedestrian and vehicle traffic.

[0039] The slide block 230 can move along the extension direction of the sliding frame to further adjust the illumination position of the lighting component 30. By sliding the slide block 230 back and forth, it can be adjusted to different positions. After the position of the slide block 230 is fixed, since the lighting component 30 itself is rotatably connected to the slide block 230, rotating the lighting component 30 can also adjust the illumination direction of the lighting component 30 so as to illuminate the road surface or the bridge guardrail 40, so as to avoid directly illuminating the eyes of pedestrians or drivers and causing interference.

[0040] In a preferred embodiment of the present invention, the slide 230 is U-shaped to form an installation space, and the lighting component 30 is installed in the installation space.

[0041] It should be noted that the U-shape provides a recessed installation space for the lighting component 30, which greatly improves the ease of installation and avoids the lighting component 30 protruding outward, resulting in a smoother and more integrated overall structure.

[0042] In a preferred embodiment of the present invention, the bottom of the slide block 230 is recessed to form a slide groove 231 that matches the movable frame 220, and the slide block 230 is sleeved and connected to the movable frame 220 through the slide groove 231.

[0043] It should be noted that the slide groove 231 facilitates the connection between the slide block 230 and the movable frame 220, so that the slide block 230 can be slidably connected to the movable frame 220. The matching of the slide groove 231 and the movable frame 220 means that the shape and size of the part of the slide groove 231 that connects to the movable frame 220 are the same, which facilitates installation.

[0044] In a preferred embodiment of this utility model, it further includes an adjusting screw 221 and a slider 222. The movable frame 220 is provided with a slide rail 223. The adjusting screw 221 is disposed in the slide rail 223 and its two ends are rotatably connected to the movable frame 220. The slider 222 is threadedly connected to the adjusting screw 221 and disposed in the slide rail 223. The slider 222 is fixedly connected to the bottom side of the slide block 230.

[0045] It is worth noting that the adjusting screw 221 and the slider 222 are used in conjunction to drive the slide block 230 to slide. A slide rail 223 is provided on the movable frame 220 for the slider 222 to slide. The slider 222 is fixedly connected to the bottom side of the slide block 230 so that the sliding of the slider 222 drives the slide block 230 to slide together. Specifically, the two ends of the adjusting screw 221 are rotatably connected to the slide rail 223 in the movable frame 220. The slider 222 is threaded onto the adjusting screw 221. When the adjusting screw 221 rotates, the rotation of the thread can drive the slider 222 to slide along the slide rail 223, which is equivalent to a lead screw structure. This realizes the movement of the slide block 230, thereby adjusting the position of the lighting component 30.

[0046] In a preferred embodiment of the present invention, the lighting assembly 30 includes a lamp holder 310 and a lighting lamp 320. The two ends of the lamp holder 310 are connected to the slide 230 and disposed in the installation space, and the lamp holder 310 itself is rotatably disposed. The lighting lamp 320 is connected to the lamp holder 310.

[0047] It is worth noting that the lamp holder 310 is used for mounting and connecting the lighting lamp 320, and the lamp holder 310 itself is rotatably connected to the mounting space of the slide 230. Thus, by rotating the lamp holder 310, the lighting lamp 320 is driven to rotate, thereby adjusting the illumination direction of the lighting lamp 320.

[0048] Furthermore, the lighting assembly 30 also includes an angle limiting mechanism 330, which includes a connecting shaft 331 and a limiting bolt 332. The connecting shaft 331 protrudes from the end of the lamp holder 310, and the two ends of the slide block 230 are recessed to form mounting grooves 232. The mounting grooves 232 are stepped, and the connecting shaft 331 is rotatably connected to the mounting grooves 232. The connecting shaft 331 is recessed to form mounting screw holes 3311, and the limiting bolt 332 is threaded into the mounting screw holes 3311 to abut against the stepped surface in the mounting grooves 232.

[0049] It should be noted that the angle limiting mechanism 330 is used to limit the rotation of the lighting component 30 after the illumination direction of the lighting component 30 is determined, so as to prevent the lighting component 30 from rotating its illumination direction on its own when subjected to external force collisions or other interference conditions. Specifically, it includes a connecting shaft 331 and a limiting bolt 332. The connecting shaft 331 allows the lamp holder 310 to be rotatably connected to the mounting groove 232 of the slide 230. Therefore, the connecting shaft 331 protrudes from the end of the lamp holder 310. Meanwhile, the connecting shaft 331 also has a recessed mounting screw hole 3311, which is used for tightening the limiting bolt 332. In conjunction with the stepped feature of the mounting groove 232, when the orientation of the lamp holder 310 is determined, the limiting bolt 332 is tightened so that the limiting bolt 332 abuts against the stepped surface in the middle of the mounting groove 232, thereby applying a clamping force to the entire structure and achieving the limiting effect. When it is necessary to adjust the orientation of the lamp holder 310, it can be loosened and rotated.

[0050] Furthermore, the fixing component 10 includes a first fixing hoop 110 and a second fixing hoop 120, which are interconnected and enclose to form a fixing space for the support leg 410 of the bridge guardrail 40 to pass through, and the movable seat 210 is connected to the second fixing hoop 120.

[0051] It should be understood that using two fixing hoops facilitates the coordination with the support leg 410 structure of the bridge guardrail 40. If the support leg 410 of the bridge guardrail 40 is cylindrical, a semi-circular fixing hoop can be provided. However, the bridge guardrail 40 in this application is square columnar, so the fixing hoop is rectangular to enclose and form a square fixing space. The movable seat 210 is connected to the second fixing hoop 120, and the first fixing hoop 110 is located on the back of the bridge guardrail 40.

[0052] Furthermore, it also includes two L-shaped connecting pieces 240 arranged opposite each other along the width direction of the slide block 230. The L-shaped connecting pieces 240 are connected to the side of the slide block 230 away from the movable seat 210, and limit screw holes 241 are provided on both surfaces of the L-shaped connecting pieces 240 and on the bridge guardrail 40.

[0053] It should be noted that the L-shaped connecting piece 240 facilitates the sliding of the entire slide block 230 to the target position, and then the bolts pass through the limiting screw holes 241 on the L-shaped connecting piece 240 to fix it to the entire bridge guardrail 40, thereby improving the overall structural stability. It is worth mentioning that corresponding limiting screw holes 241 are provided in the middle of the vertical part and the horizontal part at the bottom of the bridge guardrail 40, so that the limiting screw holes 241 on the L-shaped connecting piece 240 and the limiting screw holes 241 on the bridge guardrail 40 correspond after the slide block 230 slides to the target position. Furthermore, when arranged horizontally, when the slide blocks 230 of the two lighting units abut against each other, their respective L-shaped connecting pieces 240 will also correspond. Connecting the two L-shaped connecting pieces 240 with bolts can also improve the overall structure.

[0054] Furthermore, the first fixing hoop 110 and the second fixing hoop 120 are detachably connected by bolts.

[0055] It should be noted that this facilitates the easy assembly and disassembly of the first fixing hoop 110 and the second fixing hoop 120, making it convenient for later maintenance and replacement.

[0056] This application also provides a bridge guardrail 40, including a guardrail body having two legs 410 arranged opposite to each other along its own extension direction, and an adjustable lighting structure as described above, wherein two lighting units of the adjustable lighting structure are respectively connected to the two legs 410 by a fixing component 10.

[0057] It is understood that the fixing components 10 of the two lighting units in this application are respectively sleeved and connected to the two support legs 410, so as to be evenly distributed on the bridge guardrail 40 and ensure sufficient illumination range.

[0058] To facilitate understanding by those skilled in the art, the work adjustment process is briefly described as follows:

[0059] During installation, the first fixing hoop 110 and the second fixing hoop 120 can be placed on the support legs 410 on both sides of the bridge guardrail 40. The first fixing hoop 110 and the second fixing hoop 120 are then fixed with bolts. Afterwards, the limiting screw holes 241 on the L-shaped connecting piece 240 are aligned with the vertical limiting screw holes 241 on the bridge guardrail 40, and bolts are screwed in for fixation. Refer to the attached document for further details. Figure 1 The lamp holder 310 and the lighting lamp 320 are arranged vertically. When the lighting lamp 320 is turned on, it can illuminate the vertical part of the bridge railing.

[0060] If it is necessary to adjust the lighting lamp 320 to a horizontal arrangement, the bolt screwed into the limiting screw hole 241 can be removed, and the angle restriction on the movable frame 220 and the movable seat 210 can be released (by loosening the limiting bolt 332 to disengage from the stepped surface of the mounting groove 232). Then, the movable frame 220 can be flipped over to expose one end of the adjusting screw 221. At this time, by rotating the adjusting screw 221, it can drive the slider 222 to move through the threaded engagement with the slider 222, so that the slider 222 moves within the slide rail 223. Slide and move the slide block 230. When the slide block 230 moves, it can move the connected lamp holder 310 and the lighting lamp 320. The moving length of the slide block 230 can be adjusted according to the distance between the two lighting lamps 320. After adjustment, rotate the movable seat 210 to make it rotate the movable frame 220 and the slide block 230 to a horizontal position, so that the L-shaped connecting pieces 240 on the two slide blocks 230 are aligned. Then screw the bolts into the limiting screw holes 241 on the two L-shaped connecting pieces 240, so that the lighting lamp 320 is set horizontally and attached. Figure 2 In this state, the bridge deck or sidewalk can be illuminated by turning on the lighting 320. Before adjusting the lighting 320 to a horizontal arrangement, the limiting bolt 332 can be rotated to disengage the limiting bolt 332 from the stepped surface of the inner wall of the mounting groove 232. At this time, the angle restriction on the lamp holder 310 can be released, thereby allowing the angle of the lamp holder 310 to be adjusted to change the orientation of the lighting 320. The lighting 320 can be directed towards the bridge guardrail 40 or the bridge deck. After adjusting the orientation of the lighting 320, the limiting bolt 332 can be rotated in the opposite direction to reset it. The limiting bolt 332 will then move back to its original position and press against the stepped surface of the inner wall of the mounting groove 232. The installation can then be completed by rotating the limiting bolt 332 to reset the angle.

[0061] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
