[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] like Figures 1 to 4As shown, an embodiment of this utility model of a municipal guardrail that is easy to assemble and disassemble includes a post 1; multiple posts 1 are provided; two sets of mounting grooves 10 are opened in the middle of the post 1; the two sets of mounting grooves 10 are arranged opposite each other; a bidirectional screw rod 11 is rotatably connected to the middle of the post 1; two limiting grooves 12 are opened in the middle of the post 1; two nuts 13 are installed in the middle of the bidirectional screw rod 11; the nuts 13 are disposed inside the limiting grooves 12; two fixing plates 14 are fixedly connected to the middle of the nuts 13; the two fixing plates 14 are arranged opposite each other; the fixing plates 14 A fixing rod 15 is fixedly connected in the middle; a through hole 17 is opened between the limiting groove 12 and the mounting groove 10; two railings 18 are installed in the middle of the two posts 1; the two ends of the railings 18 are installed in the middle of the mounting groove 10; two fixing grooves 16 are opened in the middle of the railings 18; the two fixing grooves 16 are located at the ends of the railings 18; a protective plate 19 is fixedly connected in the middle of the two railings 18; a buffer component 2 is provided in the middle of the protective plate 19; an anti-collision component 3 is provided in the middle of the post 1; when installing the guardrail, first connect the two railings 18. Insert one of the posts 1 into one side, so that the end of the railing 18 enters the mounting groove 10. After placing the corresponding railing 18, hold the end of the double-acting screw 11 and rotate it. When the double-acting screw 11 rotates, the two nuts 13 move to both sides, and at the same time, the two fixing rods 15 move to one side of the railing 18. The fixing rods 15 enter the fixing groove 16 through the through hole 17, and fix the end of the railing 18 through the fixing rods 15. Repeat the above steps to connect multiple posts 1 through the railings 18, thereby installing the guardrail. When disassembling the guardrail, rotate the double-acting screw 11 in the opposite direction, so that the two nuts 13 move to the other side, and the fixing rods 15 move out of the fixing groove 16 and into the limiting groove 12. The above structure can quickly install and fix the guardrail, reducing the time for disassembling and assembling the guardrail. It does not require complicated installation steps and tools, making the installation process simpler and faster. When the guardrail is damaged and needs to be repaired or replaced, it can enable maintenance personnel to quickly replace the damaged parts, reducing the interference of cumbersome operations on traffic.
[0020] like Figures 1 to 4As shown, the buffer assembly 2 includes a fixing block 21; the fixing block 21 is fixedly connected to the middle of the guardrail 18; two fixing blocks 21 are arranged opposite each other; an elastic plate 22 is fixedly connected to the middle of the two fixing blocks 21; the elastic plate 22 is fixedly connected to the outside of the protective plate 19; multiple buffer heads 23 are fixedly connected to the middle of the protective plate 19; during operation, when the guardrail is hit by a vehicle, it first comes into contact with the elastic plate 22. When the elastic plate 22 is subjected to pressure, it bends elastically and is squeezed against the protective plate 19. The impacted elastic plate 22 comes into contact with the buffer heads 23, and the buffer heads 23 absorb the impact force of the elastic plate 22 on the protective plate 19. Through the above structure, when a vehicle accidentally hits the guardrail, the elastic plate 22 can quickly absorb and disperse the impact force generated by the external force, reducing the degree of damage to vehicles and personnel. The combined use of the elastic plate 22 and the buffer heads 23 can maintain the overall stability of the guardrail when it is hit, reduce the problem of the guardrail breaking or deforming, and enable the guardrail to provide continuous protection.
[0021] like Figures 1 to 3 As shown, the anti-collision component 3 includes multiple sets of springs 31; multiple sets of springs 31 are fixed to the side wall of the column 1; each pair of springs 31 forms a group; an anti-collision plate 32 is fixed to the end of each pair of springs 31; the anti-collision plate 32 is L-shaped; the anti-collision plate 32 is flexible; the anti-collision plate 32 is fixed to the corner of the column 1; during operation, when a pedestrian or vehicle accidentally collides with the corner of the column 1, the flexibility of the anti-collision plate 32 makes contact with it and squeezes against the spring 31, causing the spring 31 to elastically contract, absorbing and dispersing the impact force generated by the collision. Through the above structure, when a vehicle or pedestrian accidentally hits the corner of the guardrail, the flexibility of the anti-collision plate 32 and the elasticity of the spring 31 can effectively absorb and disperse the impact force, reduce the damage caused to the vehicle and pedestrian by the impact, and reduce the problem of deformation and damage to the column 1 due to the impact, thereby reducing maintenance costs.
[0022] like Figure 1 , Figure 2 , Figure 4As shown, one of the railings 18 has two first grooves 4 on its side wall; the two first grooves 4 are arranged opposite each other; a light strip 41 is installed in the middle of the first groove 4; two sets of slots 42 are provided on the side wall of the railing 18; a mounting block 43 is installed in the middle of the slot 42; a protective cover 44 is fixed to the middle of the two mounting blocks 43; the protective cover 44 is set at the corresponding position of the first groove 4; the protective cover 44 is transparent; when in operation, light strips 41 are installed on both sides of the railing 18. At night or in environments with low visibility, the light emitted by the light strips 41 alerts surrounding vehicles and pedestrians. When the light strips 41 need to be replaced or repaired, the protective cover 44 is moved upward to open the inside of the first groove 4 for replacement of the light strips 41. The above structure can effectively improve nighttime visibility, effectively play a warning role, guide vehicles and pedestrians to pass safely, and the installation of the protective cover 44 allows for quick replacement and repair of the light strips 41, making the operation more convenient and reducing the cumbersome operation of disassembling the whole.
[0023] like Figure 1 , Figure 2 , Figure 4 As shown, a second groove 5 is provided at the top of the railing 18; a solar panel 51 is installed in the middle of the second groove 5; when working, under the sunlight, the second groove 5 absorbs the sunlight and stores a certain amount of electrical energy, which is then transferred to the light strip 41 to provide power to the light strip 41. Through the above structure, energy consumption can be effectively reduced, energy conservation and emission reduction can be achieved, and a stable power supply can be provided to the light strip 41, reducing dependence on external power and energy.
[0024] like Figure 1 and Figure 3 As shown, two sets of third grooves 6 are provided on the side wall of the post 1; the third grooves 6 are located at the corresponding mounting grooves 10; a sealing strip 61 is fixedly connected to the middle of the third groove 6; during operation, when the railing 18 is installed inside the mounting groove 10, the sealing strip 61 is tightly attached to the surface of the railing 18, preventing external dust, impurities and moisture from entering the mounting groove 10 through the gap between the railing 18 and the post 1. The above structure can reduce the entry of dust and impurities from the road environment into the interior of the post 1 through the gap between the railing 18 and the post 1, reduce the corrosion and wear of internal parts caused by dust and rainwater entering the interior of the post 1, and reduce the difficulty of cleaning the interior of the post 1.
[0025] like Figure 1 and Figure 2 As shown, a rubber pad 7 is installed at the bottom of the column 1; the rubber pad 7 is fixed to the bottom of the column 1; during operation, when the column 1 is placed on the ground, it directly contacts the ground through the rubber pad 7. The above structure can effectively reduce the friction between the column 1 and the ground, reduce the problem of wear caused by increased friction due to direct contact between the column 1 and the ground, and effectively reduce the damage to the column 1.
[0026] During installation, the guardrail is first inserted into one side of one of the posts 1, with the ends of the guardrail 18 entering the mounting groove 10. After placing the corresponding guardrail 18, the end of the double-acting screw 11 is held and rotated. As the double-acting screw 11 rotates, the two nuts 13 move to both sides, and the two fixing rods 15 move to one side of the guardrail 18. The fixing rods 15 enter the fixing groove 16 through the through hole 17, fixing the ends of the guardrail 18. The above steps are repeated to connect multiple posts 1 through the guardrail 18, thus installing the guardrail. When disassembling the guardrail, the double-acting screw 11 is rotated in the opposite direction, causing the two nuts 13 to move to the other side, allowing the fixing rods 15 to move out of the fixing groove 16 and into the limiting groove 12. When the guardrail is hit by a vehicle, it first contacts the elastic plate 22. When the elastic plate 22 is subjected to pressure, it bends elastically and is squeezed against the protective plate 19. The impacted elastic plate 22 contacts the buffer head 23, and the impacted elastic plate 22 contacts the buffer head 23. The impact force of the elastic plate 22 on the protective plate 19 is absorbed. When a pedestrian or vehicle accidentally collides with the corner of the post 1, the flexibility of the anti-collision plate 32 makes contact with it and squeezes the spring 31, causing the spring 31 to elastically contract, absorbing and dispersing the impact force generated by the collision. Light strips 41 are installed on both sides of the railing 18. At night or in environments with low visibility, the light emitted by the light strips 41 alerts surrounding vehicles and pedestrians. When the light strips 41 need to be replaced or repaired, the protective cover 44 can be moved upward to open the inside of the first groove 4 for replacement of the light strips 41. Under sunlight, the second groove 5 absorbs sunlight and stores a certain amount of electrical energy, which is transferred to the light strips 41 to provide power for them. When the railing 18 is installed inside the mounting groove 10, the sealing strip 61 is tightly attached to the surface of the railing 18, preventing external dust, impurities and moisture from entering the mounting groove 10 through the gap between the railing 18 and the post 1. When the post 1 is placed on the ground, it is in direct contact with the ground through the rubber pad 7.
