Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of municipal construction, and in particular to a municipal guardrail. Background Technology
[0002] Municipal guardrails, also known as urban road guardrails or traffic guardrails, are safety facilities used in urban roads, streets, bridges, and other traffic locations. They are primarily used to separate traffic flows, protect pedestrian safety, guide vehicle traffic, and reduce traffic accidents. Municipal guardrails not only serve traffic control and separation functions but also effectively protect road users from impacts, preventing vehicles from running off the road and entering dangerous areas.
[0003] Municipal guardrails typically employ a fixed design, primarily consisting of three parts: posts, beams, and railings. The posts provide stable support through their ground-based foundation; the beams connect the posts, ensuring the overall structural stability of the guardrail; and the railings, connected to the beams, serve to isolate, protect, and guide traffic. This design, through its fixed post and beam system, withstands external forces, ensuring long-term stable use of the guardrails in various environments, preventing vehicles and pedestrians from entering dangerous areas, and effectively guaranteeing traffic safety.
[0004] In existing technologies, some municipal guardrails are typically designed as fixed structures, making them difficult to disassemble and reinstall quickly after installation. This not only increases the difficulty of maintenance and replacement but also requires significant manpower and time to adjust the position and spacing of the guardrails, reducing work efficiency. Furthermore, existing guardrails are mostly connected by welding, which often requires specialized tools and techniques for disassembly, increasing the complexity and cost of the operation. Therefore, this paper proposes a new type of municipal guardrail to address these problems. Utility Model Content
[0005] This utility model proposes a municipal guardrail, which aims to improve the problem that some guardrails in the prior art cannot be adjusted or disassembled.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A municipal guardrail includes two posts, with anti-tilting legs fixedly connected to the bottom of each post. Two crossbeams are fixedly connected to the adjacent side of the two posts, i.e., the side away from the outside of the posts. A limiting component providing position restriction is fixedly connected to the top of one of the crossbeams, and an adjustment mechanism is slidably connected to the top of the other crossbeam. Two connecting mechanisms are fixedly connected to the outside of the posts.
[0008] The adjustment mechanism includes two sliding blocks. The bottom of the sliding blocks is slidably connected to the top of one of the columns. A telescopic column is fixedly connected to the side of the two sliding blocks that is close to each other, i.e. the side away from the sliding blocks. A spring is sleeved and connected to the outside of the telescopic column. A fixing plate is slidably connected to the top of the sliding blocks.
[0009] As a further description of the above technical solution:
[0010] The limiting assembly includes multiple crossbeams, the bottom of which is fixedly connected to the top of one of the anti-tilt legs, and a limiting block is fixedly connected to the top of the crossbeams. The bottom of the limiting block is slidably connected to the bottom of the fixed plate.
[0011] As a further description of the above technical solution:
[0012] The connecting mechanism includes a connecting column 1, which is externally fixedly connected to the right side of the column, and a spherical groove is externally fixedly connected to the connecting column 1.
[0013] As a further description of the above technical solution:
[0014] A rotating ball is rotatably connected inside the spherical groove, and a second connecting column is fixedly connected to the outside of the rotating ball. The second connecting column is fixedly connected to the left side of the column.
[0015] As a further description of the above technical solution:
[0016] A railing is fixedly connected to the top of the fixed plate, and a reflective layer is fixedly connected to the outside of the railing. The upper and lower ends of the railing are slidably connected to the adjacent sides of the two anti-tilt legs.
[0017] As a further description of the above technical solution:
[0018] One end of the spring is fixedly connected to the side of the two sliding blocks that is close to each other, i.e., the side away from the two sliding blocks. The outside of the sliding blocks is slidably connected to the outside of the crossbeam.
[0019] As a further description of the above technical solution:
[0020] A force-bearing column is fixedly connected to the outer side of each of the two sliding blocks, i.e., the side away from the two sliding blocks and close to them. The outer side of the force-bearing column is slidably connected to the outside of the crossbeam.
[0021] As a further description of the above technical solution:
[0022] The bottom of the railing is slidably connected to the top of the limiting block, and the top of the limiting block is fixedly connected to the bottom of the reflective layer.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the sliding block is squeezed towards the middle by squeezing the force-bearing columns at both ends, thereby squeezing the telescopic column and the spring to eliminate the restriction of the railing, allowing it to slide on the crossbeam to adjust the spacing between the railings. It can also be disassembled during transportation, which is convenient for subsequent assembly.
[0025] 2. In this utility model, when the guardrail is placed, the left and right ends of the two guardrails are installed together. When encountering a section that needs to be turned, the rotating ball rotates inside the spherical groove, so that the guardrail can be rotated directly without the need for further installation and disassembly.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0034] Reference Figures 2 to 4This utility model provides an embodiment of a municipal guardrail, comprising two posts 1. Each post 1 is a cylindrical structure with a certain height and thickness, made of a sturdy and corrosion-resistant metal material, such as high-quality carbon steel. Anti-tilting legs 2 are fixedly connected to the bottom of each post 1. The anti-tilting legs 2 are made of the same metal material as the post 1, such as carbon steel, which significantly enhances the stability of the post 1. When subjected to external impacts, such as vehicle collisions and strong winds, the anti-tilting legs effectively prevent the post 1 from tilting or even collapsing, ensuring the structural safety and reliability of the entire municipal guardrail. The two posts 1... Two crossbeams 3 are fixedly connected to the side closest to the column 1. The crossbeams 3 are generally long and thin rod-shaped structures, usually cuboid in shape, and made of metal, such as aluminum alloy. A limiting component that provides position restriction is fixedly connected to the top of one of the crossbeams 3. The limiting component includes multiple crossbeams 3. The bottom of the crossbeams 3 is fixedly connected to the top of one of the anti-tilt legs 2. A limiting block 4 is fixedly connected to the top of the crossbeams 3. The limiting block 4 is generally block-shaped and made of metal, such as carbon steel, to better achieve the limiting effect. The bottom of the limiting block 4 is slidably connected to the bottom of the fixing plate 5.
[0035] One of the crossbeams 3 has an adjustment mechanism slidably connected to its top. The adjustment mechanism includes two sliding blocks 6, each a block-shaped structure made of metal, such as carbon steel. A load-bearing column 7 is fixedly connected to the outer side of each sliding block 6 (the side furthest from the two sliding blocks 6). The load-bearing column 7 is a slender cylinder made of metal, such as alloy steel. The outer side of the load-bearing column 7 is slidably connected to the outside of the crossbeam 3. The bottom of the sliding blocks 6 is slidably connected to the top of one of the columns 1. A telescopic column 8 is fixedly connected to the side of the sliding block 6 that is closest to it (i.e., the side furthest from the sliding block 6). The telescopic column 8 is a slender cylindrical shape made of metal, such as carbon steel. A spring 9 is sleeved on the outside of the telescopic column 8. The spring 9 has a spiral elastic structure and is made of high-quality carbon steel, which has good elasticity and fatigue life. One end of the spring 9 is fixedly connected to the side of the two sliding blocks 6 that is closest to it (i.e., the side furthest from the two sliding blocks 6). The outside of the sliding blocks 6 is slidably connected to the outside of the crossbeam 3. A fixed plate 5 is slidably connected to the top of block 6. The fixed plate 5 has a plate-like structure and is made of metal, such as carbon steel. A railing 10 is fixedly connected to the top of the fixed plate 5. The railing 10 has a long strip-like structure with a certain length and shape and is made of metal, such as stainless steel. The surface of the railing 10 is smooth, which facilitates visual observation and reduces the adhesion of dust and debris. The bottom of the railing 10 is slidably connected to the top of the limiting block 4. The top of the limiting block 4 is fixedly connected to the reflective surface. At the bottom of layer 11, a reflective layer 11 is fixedly connected to the outside of railing 10. The reflective layer 11 is a thin film structure with reflective function. Its material is a reflective material with a high reflectivity, such as microprism reflective film material. In the dark environment at night, when light shines on the reflective layer 11, it can reflect the light back, which plays a clear warning role, reminding pedestrians and vehicles to pay attention to the existence of the guardrail and avoid accidents such as collisions. The upper and lower ends of railing 10 are slidably connected to the adjacent side of two anti-tilt legs 2.
[0036] Reference Figure 1 , Figure 5The external fixed connection of column 1 has two connecting mechanisms, including connecting column one 12, which is a slender cylindrical shape made of metal, such as carbon steel. Connecting column one 12 is externally fixed to the right side of column 1. Connecting column one 12 is externally fixed to a spherical groove 13, which is a spherical groove structure with a certain depth and internal space, made of metal, such as carbon steel. The inner wall is finely processed and has a high degree of smoothness, so that the rotating ball 14 can rotate flexibly inside it. Rotating ball 14 is rotatably connected inside the spherical groove 13. Rotating ball 14 is spherical in shape and made of metal, such as alloy steel. Connecting column two 15 is externally fixed to the rotating ball 14, which is a slender cylindrical shape made of metal, such as carbon steel. Connecting column two 15 is externally fixed to the left side of column 1.
[0037] Working Principle: First, the posts 1, serving as the main supporting structure of the guardrail, are fixed to the ground, and the anti-tilt legs 2 connected at the bottom enhance overall stability. Two posts 1 are connected by a crossbeam 3. During the installation and use of the guardrail, when the spacing needs to be adjusted, the operator squeezes the force-bearing posts 7 at both ends, causing the sliding blocks 6 to press towards the center. This compression of the telescopic posts and springs 9 provides the necessary elasticity, ensuring the stability of the guardrail structure during adjustment and eliminating the restriction on the railings. This allows the railings to slide on the crossbeam 3 to adjust the distance between the railings 10. After adjustment, the connection between the fixing plate 5 and the railings 10 ensures the overall structure of the guardrail remains stable, further enhancing its safety. Furthermore, the reflective layer 11 of the guardrail effectively reflects light at night and in low-light conditions, alerting pedestrians and vehicles to the presence of the guardrail and preventing accidental collisions.
[0038] When placing the guardrail, the left and right ends of the two guardrails are installed together. When encountering a section that needs to bend, the rotating ball 14 rotates inside the spherical groove 13, allowing the guardrail to rotate directly and bend directly. Through the design and cooperation of this series of structures, the municipal guardrail of this utility model not only has good safety performance, but can also flexibly respond to changes in the urban environment and meet the actual needs of municipal management.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
