Description

Technical Field

[0001] This utility model relates to the field of outdoor safety warning devices, and in particular to a night-light safety technology service warning block for nighttime use. Background Technology

[0002] Nighttime luminous safety warning blocks are functional safety warning devices specifically designed for low-light environments at night. They are widely used in road construction, municipal maintenance, and outdoor engineering operations. Their core utilizes a dual warning structure of "self-illumination + reflection." Warning patterns / letters made from rare-earth long-lasting luminous powder emit light autonomously without a source, while a high-refractive-index reflective film provides long-distance reflection even with a light source. Combined with rectangular sign covers, metal poles, and mounting chassis, these blocks convey safety information such as danger zone boundaries and construction warnings to passing personnel and vehicles at night. This overcomes the shortcomings of traditional non-luminous warning signs in terms of poor nighttime visibility, reducing the risk of collisions and accidental entry due to obstructed vision. It is an important component of nighttime outdoor safety protection systems. However, existing warning blocks mostly rely on simple fixing of the mounting chassis to the ground (such as connection by expansion bolts alone), lacking additional counterweight structures. When encountering strong winds at night (wind force ≥ level 5), the rectangular sign cover, as the windward side, will bear a large horizontal thrust, and the fixing force between the chassis and the ground is insufficient to offset the overturning moment generated by the thrust, easily causing the warning block to tip over. Once it tipped over, the self-illuminating warning pattern / letter and reflector will deviate from the normal warning height (such as dropping from 1.2 meters to the ground), making it difficult for people and vehicles to see at night, directly losing its warning function. Even the tipped metal pole and rectangular sign cover may become road obstacles, causing secondary safety hazards (such as vehicle running over or colliding with them). Although some warning blocks have simple support structures, the connection between the metal pole and the rectangular cover is not rigid enough, and there is no effective wind transmission and buffering design. Under strong winds at night, the rectangular cover will shake violently (the shaking amplitude can reach more than 15°). On the one hand, the shaking will cause the self-illuminating warning pattern / font to frequently shift, making it difficult for people and vehicles to steadily capture the warning information and reducing recognition efficiency. On the other hand, long-term violent shaking will aggravate the wear of the connection parts of various components (such as the welding joint between the metal pole and the chassis, and the bonding joint between the transparent protective sheet and the rectangular cover), which may cause the transparent protective sheet to crack and the reflective film to fall off, damaging the core function of the warning block and shortening its service life. Utility Model Content

[0003] The main purpose of this utility model is to propose a nighttime luminous safety technology warning block, which aims to solve the problem that existing warning blocks are mostly simply fixed to the ground by a mounting base without additional counterweight. When encountering winds of level 5 or higher at night, the rectangular sign cover is subjected to horizontal thrust, and the fixing force of the base is insufficient to resist the overturning moment, which easily causes the warning block to tip over. This causes the self-illuminating warning pattern, font, and reflector to deviate from the normal height, lose their warning function, and may also become a road obstacle, causing secondary hazards.

[0004] To address the aforementioned issues, this utility model proposes a nighttime luminous safety service warning block, comprising a mounting base and a metal pole vertically welded to the center of the top of the mounting base. A rectangular sign cover is provided on the front side of the top of the metal pole, and a pole fixing sleeve is vertically welded to the center of the outer wall of the rear end of the rectangular sign cover. The top of the metal pole is inserted into the pole fixing sleeve, and the metal pole and the pole fixing sleeve are fixedly connected by welding. Heavy-duty wind-resistant devices are provided on the outer wall of the rear end of the rectangular sign cover near the lower left and lower right corners.

[0005] In one embodiment, the heavy-duty wind-resistant device on the outer wall of the rear end of the rectangular sign cover near the lower right corner includes a cement heavy-duty block, a strip-shaped fitting bracket, and a connecting groove. The strip-shaped fitting bracket is located on the right side of the mounting base and is arranged in a longitudinal front-to-back configuration. Cement heavy-duty blocks are provided on both the front and rear sides of the center of the strip-shaped fitting bracket. A connecting groove is provided inside the center of the bottom end of the cement heavy-duty block, and the cement heavy-duty block is fitted onto the left and right ends and the top of the strip-shaped fitting bracket through the connecting groove.

[0006] In one embodiment, the heavy-duty wind-resistant device further includes a rod connecting block, a strip-shaped welded plate, and a rod through hole. The strip-shaped welded plate is welded and fixed vertically to the outer wall of the rear end of the rectangular cover near the lower right corner. The rod connecting block is welded to the rear end of the bottom of the strip-shaped welded plate, and a rod through hole is provided inside the center of the rod connecting block.

[0007] In one embodiment, the heavy-duty wind-resistant device further includes a metal rod and a metal reinforcing sleeve B. The metal rod is inserted into the through hole of the rod, and the metal reinforcing sleeve B is welded to the center of the outer wall of the top of the strip-shaped fitting bracket. The bottom end of the metal rod is inserted into the metal reinforcing sleeve B, and the metal rod is fixedly connected to the metal reinforcing sleeve B by welding.

[0008] In one embodiment, the heavy-duty wind-resistant device further includes locking nut A and locking nut B. The top quarter of the metal rod is threaded, and locking nut A and locking nut B are threaded onto the outer side of the metal rod near the top. Locking nut A and locking nut B are located at the top and bottom of the rod connecting block, respectively.

[0009] In one embodiment, the heavy-duty wind-resistant device further includes two anti-detachment blocks, which are respectively welded to the top of the front and rear ends of the strip-shaped bonding bracket. The anti-detachment blocks can prevent the cement heavy-duty block from sliding outward from the front and rear ends of the strip-shaped bonding bracket.

[0010] In one embodiment, after the locking nut A and locking nut B are tightened on the top and bottom outer walls of the boom connecting block, respectively, the metal boom can be prevented from moving up and down in the boom through hole. The length of the metal boom is greater than the distance between the bottom outer wall of the boom connecting block and the bottom outer wall of the mounting chassis.

[0011] In one embodiment, a metal reinforcing sleeve A is welded to the center of the outer wall at the top of the mounting chassis. The bottom end of the metal upright is inserted into the metal reinforcing sleeve A, and the metal upright is fixedly connected to the metal reinforcing sleeve A by welding. The mounting chassis has a circular shape when viewed from above, and multiple mounting holes are equidistantly arranged inside the mounting chassis near the edge.

[0012] In one embodiment, the metal pole is a hollow metal pole, the upper and lower ends of the pole fixing sleeve are flush with the outer walls of the upper and lower ends of the rectangular sign cover, and the top of the pole fixing sleeve is sealed. A transparent protective sheet is sealed and fixed inside the front opening of the rectangular sign cover.

[0013] In one embodiment, the transparent protective sheet is integrally made of transparent resin, and the area where the transparent protective sheet is attached to the rectangular sign cover is further reinforced with glass glue. A reflector is attached and fixed to the inner wall of the rear end of the rectangular sign cover, and the reflector is located behind the transparent protective sheet. The reflector includes a rectangular plate and a high refractive index reflective film, and the high refractive index reflective film is attached to the outer wall of the front end of the rectangular plate.

[0014] In one embodiment, a self-illuminating warning pattern is provided on the upper side of the center of the outer wall at the front end of the transparent protective sheet, and self-illuminating warning lettering is provided on the lower side of the center of the outer wall at the front end of the transparent protective sheet. Both the self-illuminating warning pattern and the self-illuminating warning lettering are injection molded from a mixture of rare earth long-lasting phosphorescent powder and resin. Both the self-illuminating warning pattern and the self-illuminating warning lettering are attached to the transparent protective sheet using Velcro, and can be replaced and adjusted as needed. Beneficial effects: The technical solution of this utility model adds a new type of heavy-duty wind-resistant device to the two bottom corners of the rear end of the rectangular sign cover. The heavy-duty wind-resistant device, through the dual structure design of heavy-duty fixing and rigid connection, can effectively resist the impact of outdoor wind on the warning block, and prevent the warning block from tilting, shifting or shaking in bad weather at night (such as strong winds and gusts). It ensures that the nighttime warning function of the self-illuminating warning pattern, font and reflector is stable and provides reliable support for nighttime safety warnings in road construction, outdoor operations and other scenarios. Overall, the device can significantly improve the wind resistance and safety of the warning block, while taking into account the installation flexibility and structural durability. Specifically, the device provides core counterweight through cement weight blocks. Two cement weight blocks are respectively fitted onto the front and rear sides of the strip-shaped bonding support. Utilizing the high weight characteristics of cement, it provides downward stable pressure for the entire warning block, effectively counteracting the horizontal thrust generated by strong winds on the rectangular sign cover. At the same time, the strip-shaped bonding support is arranged longitudinally front and back, which can expand the range of heavy pressure and further enhance the anti-overturning ability of the bottom of the warning block, preventing the warning block from tipping over due to concentrated wind force. This ensures that the self-illuminating warning pattern, font and reflector are always in a clearly visible warning position at night, without affecting the identification of warning information by personnel and vehicles. Furthermore, the metal rod of the device is fixed to the rod connecting block at the rear end of the rectangular sign cover through the rod through-hole, and its bottom end is welded to the metal reinforcing sleeve B on the strip-shaped fitting bracket, forming a rigid transmission link. When wind force acts on the rectangular sign cover, the metal rod can transmit the horizontal wind force to the strip-shaped fitting bracket and the concrete heavy-duty block. The stability of the heavy-duty structure is used to limit the swaying amplitude of the rectangular sign cover. At the same time, the top of the metal rod is threaded. The top and bottom ends of the rod connecting block are clamped by locking nuts A and B, respectively, which can flexibly adjust the effective length of the metal rod. When the warning block needs to be adapted to different installation environments, simply loosen the locking nuts, adjust the position of the metal rod in the rod through-hole, and then tighten the nuts again to fix it. There is no need to replace the rod or modify the bracket structure, which enhances the adaptability of the device to different scenarios, while ensuring the stability of the rod connection after adjustment and not affecting the wind resistance effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0022] This utility model provides, for example Figure 1-5The illustrated luminous safety warning block for nighttime use includes a mounting base 1 and a metal pole 4 vertically welded to the center of the top of the mounting base 1. A pole fixing sleeve 8 is vertically welded to the center of the outer wall of the rear end of a rectangular sign cover 5. The top of the metal pole 4 is inserted into the pole fixing sleeve 8, and the metal pole 4 and the pole fixing sleeve 8 are fixedly connected by welding. The mounting base 1 has a circular shape when viewed from above. The advantage of this shape compared to a square base is that it distributes the force more evenly, avoiding deformation of the base caused by stress concentration at the corners. At the same time, in complex outdoor environments (such as construction areas with collisions with debris), the circular structure can reduce bumps and damage. The mounting base 1 has multiple pre-drilled holes at equal intervals near the edge. These holes are used to fix the warning block to the ground with expansion screws. In use, the expansion screws are drilled into the asphalt, concrete, or other ground base through the pre-drilled holes. Utilizing the expansion anchoring principle of the expansion screws (when the screws are tightened, the expansion tube expands and squeezes the inner wall of the hole in the ground, generating friction and interlocking force), the base is firmly fixed to the ground, preventing the warning block from being damaged by wind, external forces, etc. The force collision causes displacement, providing stable bottom support for the entire device. The metal upright 4 is vertically welded to the center of the top of the mounting base 1, and a metal reinforcing sleeve A2 is also welded to the center of the outer wall of the top of the mounting base 1. The bottom end of the metal upright 4 is inserted into the metal reinforcing sleeve A2 and fixed by welding. The principle and advantage of this double fixing structure is that the metal reinforcing sleeve A2 can wrap around the bottom end of the metal upright 4, increasing the contact area between the upright and the base, dispersing the vertical pressure transmitted by the upright (such as the weight of the rectangular cover 5), and preventing the bottom end of the upright from being damaged due to local pressure. Excessive stress caused cracks at the weld joints. Welding ensures no relative rotation between the pole and the base, and between the pole and the reinforcing sleeve A, further enhancing structural rigidity. Meanwhile, the metal pole 4 is designed with an internal hollow structure. Compared to a solid pole, it reduces material usage and overall device weight while ensuring support strength (the metal pole 4 uses Q235 galvanized steel with a bending strength of 215MPa), thus reducing transportation and installation difficulties. The hollow structure also facilitates future cable laying (such as adding LED auxiliary light sources).

[0023] like Figure 1 , Figure 2 and Figure 3As shown, the rectangular sign cover 5 serves as the carrier and protective medium for warning information. A transparent protective sheet 6 is sealed inside the front opening, and a reflector 7 is adhered to the inner wall of the rear end, located behind the transparent protective sheet 6. The transparent protective sheet 6 is made of transparent resin in one piece. The advantage of transparent resin is its light transmittance of over 90%, which does not affect the light transmission of the self-illuminating warning pattern 9 and lettering, nor the reflective effect of the reflector 7. It also possesses impact and wear resistance (surface hardness reaches HB80, capable of withstanding small stone impacts), protecting the internal reflector 7 from outdoor dust and rain. The areas where the transparent protective sheet 6 adheres to the rectangular sign cover 5 are sealed with glass glue. The principle is to utilize the sealing and bonding properties of glass glue to fill the tiny gaps between the protective sheet and the sign cover, forming a waterproof and dustproof sealing layer. This prevents rainwater from seeping into the rectangular sign cover 5 and causing moisture damage to the reflector 7 (such as the reflective film peeling off or the rectangular sheet rusting), ensuring the nighttime warning function. The reflector 7 is designed for long-term stability and consists of a rectangular plate and a high-refractive-index reflective film. The high-refractive-index reflective film is attached to the outer front wall of the rectangular plate. The rectangular plate is made of PVC hard plastic, which is lightweight and anti-aging, and can serve as a stable carrier for the reflective film. The reflective principle of the core component, the high-refractive-index reflective film, is total internal reflection and directional reflection of light. When an external light source (such as a vehicle headlight or flashlight) shines at night, the light enters the microprism structure of the reflective film and undergoes multiple total internal reflections on the inner wall of the prism, eventually reflecting back to the light source along the original incident direction, forming a high-brightness reflective effect (reflective brightness ≥300cd / lx•m²). The advantage of this principle is that its reflective efficiency is much higher than that of ordinary reflective paint, and the recognition distance can reach more than 100 meters, allowing people and vehicles at a distance to quickly spot the warning block and take evasive action in advance. The self-illuminating warning pattern 9 and the self-illuminating warning lettering 10 are attached to the transparent protective sheet 6 with Velcro, and can be replaced and adjusted as needed.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, a self-illuminating warning pattern 9 is set on the upper side of the center of the outer wall of the front end of the transparent protective sheet 6, and a self-illuminating warning letter 10 is set on the lower side. Both are injection molded by mixing rare earth long-lasting phosphorescent powder (strontium aluminate phosphorescent powder) with resin. Its core luminescence principle is photoluminescence. During the day or when there is a light source, the activator (europium, dysprosium) in the phosphorescent powder absorbs light energy, causing electrons to transition from the ground state to a high-energy excited state and store energy. At night or when the light is dim, the electrons return from the excited state to the ground state and release the stored energy in the form of visible light, realizing self-luminescence (initial brightness ≥100mcd / m², continuous luminescence time of eight to twelve hours). The advantage of this design is that it does not require an external power supply and can independently provide warning signals in scenarios without external light sources (such as construction in remote mountainous areas or areas with power outages). It forms a complementary warning with the reflector 7. When there is a light source, it relies on the reflector 7 to achieve long-distance warning. When there is no light source, it relies on the self-illuminating structure to ensure basic warning, covering more nighttime use scenarios.

[0025] like Figure 1 , Figure 4 and Figure 5 As shown, heavy-duty wind-resistant devices 3 are installed on the outer wall of the rear end of the rectangular sign cover 5 near the lower left and lower right corners (taking the device at the lower right corner as an example, the structure at the lower left corner is symmetrical). The heavy-duty wind-resistant device 3 includes a cement heavy-duty block 12, a strip-shaped fitting bracket 13, and a connecting groove 17. The strip-shaped fitting bracket 13 is located on the right side of the mounting base 1 and is arranged in a longitudinal position. Its function is to provide a mounting carrier for the cement heavy-duty block 12, and the longitudinal arrangement can expand the stress range of the counterweight and enhance the anti-overturning ability (compared to the transverse arrangement, the longitudinal arrangement can more evenly offset the wind force in different directions). Cement heavy-duty blocks 12 are installed on the outer sides of the front and rear sides of the center of the strip-shaped fitting bracket 13. A connecting groove 17 is provided inside the center of the bottom end of the cement heavy-duty block 12, which is fitted onto the strip-shaped fitting bracket through the connecting groove 17. The advantages of this socketing method are that it is easy to install, and the heavy-duty block can be combined with the support without additional fasteners. The socket groove 17 can limit the lateral displacement of the heavy-duty block. The core function of the cement heavy-duty block 12 is to use the principle of gravity counterweight to provide downward stable pressure on the warning block through its own high weight (50-100kg per block), which counteracts the horizontal thrust generated by the wind on the rectangular sign cover 5 (the stronger the wind, the greater the anti-overturning moment provided by the heavy-duty block), and prevents the warning block from falling over as a whole. At the same time, anti-detachment blocks 11 are welded to the top of the front and rear ends of the strip-shaped support 13. Their function is to prevent the cement heavy-duty block 12 from sliding back and forth along the support (such as when a strong gust of wind hits), prevent the heavy-duty block from falling off and causing the counterweight to fail, and further improve the wind resistance stability.

[0026] like Figure 1 , Figure 4 and Figure 5As shown, the heavy-duty wind-resistant device 3 also includes a strip-shaped welded plate 16, a rod connecting block 15, a metal rod 14, and a metal reinforcing sleeve B18. The strip-shaped welded plate 16 is vertically welded to the outer wall of the rear end of the rectangular cover 5. The rod connecting block 15 is welded to the bottom rear end. A rod through hole 19 is opened at the center of the rod connecting block 15, and the metal rod 14 is inserted into the through hole. The metal reinforcing sleeve B18 is welded to the center of the outer wall of the top of the strip-shaped fitting bracket 13. The bottom end of the metal rod 14 is inserted into the reinforcing sleeve B and welded and fixed. This structure forms the rectangular cover 5 to the strip-shaped welded plate 16. The rigid transmission link from the boom connecting block 15 to the metal boom 14 to the strip-shaped fitting bracket 13, when the wind force acts on the rectangular sign cover 5, the horizontal wind force will be converted into a thrust on the sign cover. The thrust is transmitted to the strip-shaped fitting bracket 13 and the cement weight block 12 through the rigid link. The weight of the weight block and the ground friction form resistance, which limits the displacement of the bracket and the boom, thereby controlling the swaying amplitude of the rectangular sign cover 5 to within five degrees, avoiding the displacement of the self-illuminating pattern and font position and damage to the transparent protective film 6 due to violent shaking, and ensuring the continuity of the warning signal at night.

[0027] like Figure 1 , Figure 4 and Figure 5 As shown, the top quarter of the metal rod 14 is threaded, with locking nuts A20 (located at the top of the rod connecting block 15) and B21 (located at the bottom of the rod connecting block 15) fitted onto the external threads. The adjustment principle is that when the two locking nuts are loosened, the position of the metal rod 14 in the through hole can be adjusted up and down along the threads, thereby changing the relative height between the rectangular sign cover 5 and the bracket. After adjustment, the two nuts are tightened, and the self-locking characteristics of the nuts and threads (the friction between the thread teeth) are used to clamp the rod connecting block 15, preventing the metal rod 14 from moving up and down. The advantage of this design is that it can flexibly adjust the effective warning height of the warning block according to the height requirements of the outdoor installation environment (such as the height difference of the construction area boundary and the sight height of different vehicle models) without replacing the rod or modifying the bracket structure, making it more adaptable. At the same time, the structure remains rigid after locking, which does not affect the wind resistance transmission effect and ensures that the stability of the device is not compromised after adjustment.

[0028] When the heavy-duty wind-resistant device 3 is not needed, expansion bolts should be inserted into the multiple pre-drilled holes of the mounting base 1 to fix it to the ground, thereby fixing the warning block to the ground. The connection between the metal pole 4 and the pole fixing sleeve 8 can also be set to rotate, so that the warning block can be rotated and adjusted according to the needs of different directions during use.

[0029] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
