Description

Technical Field

[0001] This utility model relates to the field of warning sign technology, specifically providing a fluorescent warning sign for nighttime use. Background Technology

[0002] Self-illuminating fluorescent warning signs play a crucial role in various safety warning scenarios. Whether in dangerous areas such as road construction zones and hazardous chemical storage sites, or in temporary warning situations such as traffic control and accident scenes, these signs can emit bright light in dark environments, promptly reminding people of potential dangers and effectively reducing the probability of safety accidents.

[0003] Most existing self-illuminating fluorescent warning signs use traditional fluorescent materials to achieve their self-illuminating function. However, with the passage of time, these fluorescent materials exhibit significant aging, causing a decrease in both luminous intensity and duration. Initially, they may provide sufficiently clear and long-lasting warning light at night, but after a period of use, the luminous intensity gradually weakens and the luminous duration shortens considerably, greatly diminishing the warning effect and rendering them unable to provide reliable safety warnings.

[0004] More importantly, most self-illuminating fluorescent warning signs on the market currently adopt an integrated design. While this design ensures the product's integrity and stability to a certain extent, it reveals many drawbacks in actual use. Once the fluorescent material ages or is damaged, replacement or repair requires processing the entire warning sign. This not only means high replacement costs but also requires a significant investment of manpower and time. Moreover, due to the relatively complex structure of the integrated design, the repair process is often difficult and technically demanding, making it hard for non-professionals to complete, further increasing the difficulty of use and maintenance.

[0005] Therefore, a new technical solution is urgently needed to solve these problems existing in the current self-illuminating fluorescent warning signs. Utility Model Content

[0032] Please see Figures 1-9This utility model provides a nighttime fluorescent warning sign, which includes: a post 300, and a first box 100 installed at the top of the post 300; a second box 200 is provided on the side of the first box 100 away from the post 300; a connecting rod assembly 400 is provided between the first box 100 and the second box 200, and the connecting rod assembly 400 is located at the lower edge of the first box 100 and the second box 200; wherein: the second box 200 swings around its bottom edge through the connecting rod assembly 400; a plate fixing assembly 500 is arranged in a ring array on the inner wall of the second box 200, and the plate fixing assembly 500 is fastened to the fluorescent display board 600; a transparent protective plate 700 is provided on the side of the first box 100 away from the second box 200; the first box 100 and the second box 200 are connected by bolts 800.

[0033] In the above embodiment, the bottom ends of the first box 100 and the second box 200 are connected by a connecting rod assembly 400. When it is necessary to replace the fluorescent display board 600 inside the second box 200, the bolt 800 between the first box 100 and the second box 200 is removed, and the second box 200 is turned so that it rotates around its bottom end near the edge of the first box 100 until it is horizontal. Then, the faulty fluorescent display board 600 is removed from the plate fixing assembly 500, and the new fluorescent display board 600 is placed back in each plate fixing assembly 500. The fluorescent display board 600 is fixed by the plate fixing assembly 500. Then, the second box 200 is turned to close with the first box 100 and fixed by the bolt 800. This improves the service life of the fluorescent warning sign and also improves the portability of replacement.

[0034] Please see Figures 1-9 In some embodiments, the first box 100 includes: a first body 110, one side of which is connected to the column 300; a first cavity 120 disposed on the side of the first body 110 near the second box 200; and an elastic protective plate 130 disposed in the first cavity 120, the side of the elastic protective plate 130 away from the first body 110 abutting against the fluorescent display board 600.

[0035] In the above embodiment, the first body 110 has an overall open box-shaped structure. The first cavity 120 is used to install and abut against the back of the fluorescent display board 600. The side of the first cavity 120 near the second box 200 is open. After the fluorescent display board 600 is installed in the second box 200, the elastic protective plate 130 supports the back of the fluorescent display board 600 to improve the problem of the fluorescent display board 600 shaking in the second box 200 when the warning sign is shaken by the wind. This reduces the risk of the fluorescent display board 600 falling off the plate fixing assembly 500, and at the same time reduces the abnormal noise of the fluorescent display board 600 and extends the service life of the fluorescent display board 600.

[0036] It is worth noting that the elastic protective plate 130 can be made of lightweight foam. When the fluorescent display board 600 leaks after prolonged use, the foam can absorb the leaked fluorescent agent or fluorescent powder.

[0037] Please see Figures 1-9 In some embodiments, the second box 200 includes: a second body 210 disposed on the side of the first body 110 away from the column 300; a second cavity 220 disposed on the side of the second body 210 close to the first body 110; wherein: plate fixing components 500 are evenly distributed at each corner of the inner wall of the second cavity 220; a mounting opening 230 is disposed on the surface of the second body 210, a transparent protective plate 700 is installed in the mounting opening 230, and sealant is filled between the transparent protective plate 700 and the mounting opening 230; a mounting plate 240 is L-shaped, one end of the L-shaped mounting plate 240 is connected to the bottom end of the second body 210, and the other end extends toward the side of the second body 210 away from the first body 110; and the two ends of the connecting rod assembly 400 are respectively connected to the second body 210 and the mounting plate 240.

[0038] In the above embodiment, a second cavity 220 is provided on the side of the second body 210 near the first body 110. The fluorescent display board 600 is installed on the plate fixing assembly 500 inside the second cavity 220. The mounting port 230 is opened between the second cavity 220 and the outer wall of the second body 210. The mounting port 230 is open at both ends. The transparent protective plate 700 is installed on one side of the mounting port 230. The transparent protective plate 700 is bonded to the mounting port 230 with sealant to form a sealed light-transmitting structure. The modular design allows the transparent protective plate 700 to be replaced independently when it is scratched or aged, saving costs.

[0039] Please see Figures 1-9 In some embodiments, the first housing 100 further includes a reflector 140, which is located at the bottom of the first body 110 near the second body 210 and has an L-shaped structure with the second body 210; a reflector assembly 150 is provided on the surface of the reflector 140.

[0040] In the above embodiment, the reflector 140 provided at the bottom of the first body 110 near the second body 210 is used to refract light onto the surface of the transparent protective plate 700 when the light passes through the reflector assembly 150, and then illuminate the fluorescent display board 600 through the transparent protective plate 700. The fluorescent display board 600 stores energy by absorbing light. The more energy stored, the higher the light intensity and the longer the light emission time, which is used to increase the time that the light passes through the fluorescent display board 600.

[0041] Please see Figures 1-9In some embodiments, the linkage assembly 400 includes: a first linkage 410, one end of which is hinged to a corner of the mounting plate 240; a first L-bar 420, one end of which is hinged to the outer wall of the mounting plate 240 away from the second body 210; and a second L-bar 430, both ends of which are respectively hinged to the end of the first linkage 410 away from the mounting plate 240 and the corner of the first L-bar 420; wherein: the corner of the second L-bar 430 is hinged to the side wall of the reflector 140; a second linkage 440, one end of which is hinged to the side wall of the reflector 140, and the other end of which is hinged to the end of the second L-bar 430 away from the mounting plate 240; the first linkage 410 and the end of the first L-bar 420 near the mounting plate 240 are parallel, and a section of the second linkage 440 is parallel to a section of the second L-bar 430.

[0042] In the above embodiment, when the second body 210 is rotated around its bottom edge, the mounting plate 240 swings around the bottom of the second body 210. During the swinging process of the mounting plate 240, the distance between the parallel section of the first connecting rod 410 and the first L rod 420 increases, pushing the second L rod 430 to swing downward around its own corner. During this process, the section of the first connecting rod 410 and the first L rod 420 remains parallel, and the section of the second connecting rod 440 and the second L rod 430 remains parallel, so that the bottom edge of the second body 210 near the first body 110 always adheres to the surface of the first body 110. Compared with the traditional hinged connection using a hinge shaft, the first connecting rod 410 always pushes the bottom of the second body 210 to adhere to the surface of the first body 110. This external connection method can reduce the problem of dust and moisture entering the first cavity 120 and the second cavity 220.

[0043] Please see Figures 1-9 In some embodiments, the reflector assembly 150 includes: a first lens 151 and a second lens 152, the first lens 151 and the second lens 152 being arranged in a V-shape; a mounting groove 141, disposed on the surface of the reflector stage 140, the mounting groove 141 being V-shaped, the depth of the end of the V-shaped mounting groove 141 near the first body 110 being greater than the depth of the end away from the first body 110; a drainage groove 142, disposed in the mounting groove 141, the drainage groove 142 being disposed near the first body 110; and the first lens 151 and the second lens 152 being attached to the bottom surface of the mounting groove 141.

[0044] In the above embodiment, the first lens 151 and the second lens 152 are used to reflect sunlight. The V-shaped first lens 151 and the second lens 152 are concave towards the center, so that when sunlight shines on one side onto one of the lenses, it can be reflected onto the transparent protective plate 700. At the same time, since the depth of the mounting groove 141 near the first body 110 is greater than the depth away from the first body 110, the first lens 151 and the second lens 152 attached to the mounting groove 141 are not only V-shaped, but their normals are also tilted towards the transparent protective plate 700, which further increases the time for light to pass through the fluorescent display board 600. At the same time, when rainwater enters the reflector 140, it can also be guided through the mounting groove 141 and finally discharged through the drainage groove 142, avoiding the accumulation of rainwater in the mounting groove 141.

[0045] Please see Figures 1-9 In some embodiments, the plate fixing assembly 500 includes: elastic grippers 510, which are U-shaped and evenly distributed at the apex corners of the second cavity 220; a rotating rod 520, which passes through the outer wall of the elastic grippers 510 and connects to the inner wall of the second cavity 220, and is rotatably connected to the elastic grippers 510; and a pull rod 530, which passes through the outer wall of one end of the elastic grippers 510 and connects to the inner wall of the other end. Connections: Circular plates 540, provided in two sets, the two sets of circular plates 540 are respectively hinged to the outer walls on both sides of the pull rod 530, and the circular plates 540 are located on the side of the elastic gripper 510 away from the second cavity 220; U-shaped rod 550, with both ends connected to the circumferential outer walls of the two sets of circular plates 540; wherein: the surface of the circular plate 540 is provided with a cut 560, and the U-shaped rod 550 connects the side of the circular plate 540 away from the cut 560; anti-slip pad 570 is located on the inner wall of the opening of the U-shaped elastic gripper 510.

[0046] In the above embodiment, the open end of the U-shaped elastic gripper 510 is used to hold the fluorescent display panel. When the fluorescent display panel is placed in the opening of the elastic gripper 510, the U-shaped rod 550 is moved to one side, so that the cut 560 abuts against the outer wall of the elastic gripper 510 and gradually rotates until the arc surface abuts against the outer wall of the elastic gripper 510. The diameter of the arc surface is greater than the distance between the cut 560 and the center of the circular plate 540, so that the circular plate 540 pushes the elastic gripper 510 closer together, thereby achieving the effect of tightening the fluorescent display panel.

[0047] Please see Figures 1-9In some embodiments, the surface of the second body 210 is provided with a plurality of positioning nuts 810; the surface of the first body 110 is provided with a plurality of through holes 820, and bolts 800 pass through the through holes 820 and are threadedly connected to the positioning nuts 810; a spring 830 is sleeved on the outer circumferential wall of the positioning nuts 810; a first annular sealing groove 160 is provided on the side of the first body 110 near the second body 210, and a second annular sealing groove 250 is provided on the side of the second body 210 near the first body 110, the first annular sealing groove 160 and the second annular sealing groove 250 are respectively covered on the outside of the first cavity 120 and the second cavity 220; a sealing strip 260 is provided in the second annular sealing groove.

[0048] In the above embodiments, when the positioning nut 810 is used to connect the first body 110 and the second body 210, the bolt 800 passes through the through hole 820 and is threadedly connected to the positioning nut 810 to achieve the fastening of the first body 110 and the second body 210. After the first body 110 and the second body 210 are fastened by the bolt 800, the sealing strip 260 is fixed in the first annular sealing groove 160 and the second annular sealing groove 250. The sealing strip 260 seals the first body 110 and the second body 210 to prevent moisture or dust from entering the first cavity 120 and the second cavity 220.

[0049] Please see Figures 1-9 In some embodiments, the side of the first body 110 away from the second body 210 is provided with an installation tube 310, and the top end of the column 300 is rotatably disposed in the installation tube 310; a first torsion spring 320 and a second torsion spring 330 are provided at intervals on the circumferential outer wall of the top end of the column 300; one end of the first torsion spring 320 and the second torsion spring 330 are connected to the circumferential outer wall of the column 300, and the other end is connected to the surface of the first body 110; the elastic directions of the first torsion spring 320 and the second torsion spring 330 are opposite.

[0050] In the above embodiments, when encountering typhoon weather, the first body 110 and the second body 210 are blown and rotated by the wind. When rotating to one side, one of the torsion springs tightens and stores energy, while the other torsion spring expands. When the wind stops blowing, the tightened torsion spring pushes the first housing to reset, and the other torsion spring pulls the first housing to reset, achieving the effect of automatic reset. At the same time, it can improve the problem that the column 300 breaks due to the large wind resistance of the first body 110 and the second body 210 during typhoon weather.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
