Description

Technical Field

[0001] This utility model relates to the field of road administration engineering technology, specifically a road anti-collision device. Background Technology

[0002] In road construction projects, road crash barriers are an important component. Through scientific design and reasonable layout, they can not only improve the aesthetics and user experience of roads, but also effectively prevent vehicles from deviating from their normal driving routes, thereby reducing collisions caused by loss of control or accidents.

[0003] Common road crash barriers are usually designed as guardrails, and for ease of installation, they are typically designed for separate installation. However, when these guardrails are hit by a car, they are easily broken into pieces due to their light weight and weak connection with adjacent guardrails, resulting in mediocre protection. Therefore, we need a road crash barrier that is highly interconnected and provides good crash protection. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a road anti-collision device, comprising a fixed column one and a fixed column two fixedly connected to both ends of one side of the support back plate, an anti-pressure plate provided on one side of the support back plate, a rolling mechanism for auxiliary buffering provided on the side of the anti-pressure plate away from the support back plate, and a plug-in mechanism for improving the correlation at one end of the anti-pressure plate.

[0006] Preferably, the insertion mechanism includes a pressing block and a connecting block. One side of the connecting block is fixedly connected to the side of one end of the pressure-resistant plate, and the other side of the connecting block is fixedly connected to one side of the pressing block. The side of the second fixing column away from the pressure-resistant plate has an insertion groove. The side of the pressing block is slidably connected to the inner wall of the insertion groove. One end of the pressure-resistant plate is fixedly connected to the side of the second fixing column away from the insertion groove. The side of the first fixing column away from the pressure-resistant plate has a sliding groove. One side, top, and bottom of the pressure-resistant plate are slidably connected to the inner wall of the sliding groove. The pressing block is slidably connected to one side of the sliding groove.

[0007] Preferably, the rolling mechanism includes a roller and connecting shafts. The inner sides of the two connecting shafts are fixedly connected to the top and bottom of the roller, respectively. A rotating groove is provided on the side of the pressure-resistant plate away from the supporting back plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, by incorporating a pressing block and a connecting block, not only allows the pressure plate to move as it deforms when subjected to impact, but also enables the pressing block and connecting block to gradually extend into the insertion slot of the next adjacent device. This not only increases the connectivity between adjacent pressure plates with the magnitude of the impact force, thus enhancing the interconnectivity and making adjacent devices a unified whole, improving the protective effect, but also allows the pressing block and connecting block to transfer the impact force received by the previous pressure plate to one end of the next adjacent pressure plate, further relieving the force.

[0018] 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.

[0019] Please see Figure 1-3This utility model provides a technical solution: a road anti-collision device, including a support back plate 1, with fixed columns 2 and 5 fixedly connected to both ends of one side of the support back plate 1, an anti-pressure plate 6 provided on one side of the support back plate 1, a rolling mechanism for auxiliary buffering provided on the side of the anti-pressure plate 6 away from the support back plate 1, and a plug-in mechanism for improving correlation provided at one end of the anti-pressure plate 6, which can play a good anti-collision role.

[0020] Furthermore, the insertion mechanism includes a pressing block 3 and a connecting block 4. One side of the connecting block 4 is fixedly connected to the side of one end of the pressure-resistant plate 6, and the other side of the connecting block 4 is fixedly connected to one side of the pressing block 3. The side of the fixed column 2 5 away from the pressure-resistant plate 6 is provided with an insertion groove 9. The side of the pressing block 3 is slidably connected to the inner wall of the insertion groove 9. One end of the pressure-resistant plate 6 is fixedly connected to the side of the fixed column 2 5 away from the insertion groove 9. The side of the fixed column 2 away from the pressure-resistant plate 6 is provided with a sliding groove. One side, top, and bottom of the pressure-resistant plate 6 are slidably connected to the inner wall of the sliding groove. The pressing block 3 is slidably connected to one side of the sliding groove, which can further improve the correlation between adjacent devices and improve the protection effect.

[0021] Furthermore, the rolling mechanism includes a roller 7 and a connecting shaft 8. The inner sides of the two connecting shafts 8 are fixedly connected to the top and bottom of the roller 7, respectively. The anti-pressure plate 6 has a rotating groove on the side away from the supporting back plate 1. The surfaces of the two connecting shafts 8 are rotatably connected to the top and bottom of the inner wall of the rotating groove, which allows the surface of the roller 7 to be tangent to the impact force and rotate, thereby driving the car head to perform a correction operation, thus playing the role of unloading force.

[0022] Furthermore, a fixing groove 10 is provided on the side of the support back plate 1 away from the fixing column 1 2 and fixing column 2 5, which further improves the stability of the device when it is fixed.

[0023] Furthermore, the side of the pressing block 3 away from the connecting block 4 is set with an arc surface, which fits better against one side of the next pressure plate 6, resulting in a better pressure relief effect.

[0024] Furthermore, the pressure plate 6 is designed in an arc shape. The pressure plate 6, through the force of deformation, forms a counteracting effect against the impact force generated during a collision, thereby achieving a collision protection effect.

[0025] Furthermore, the pressure plate 6 is made of nickel-titanium alloy, a metal with good memory properties, which facilitates rebound and recovery after impact.

[0026] Working principle: First, place the device at the required installation position, and then fix the support back plate 1 at the required position using the fixing slot 10 and bolts. When installing the device, it needs to be installed according to the direction of the car's movement. For example, when the car moves from left to right, the pressing block 3 and connecting block 4 are located on the right side of the device, and vice versa. When multiple anti-pressure plates 6 need to be installed, before fixing, the pressing block 3 of the previous device needs to be inserted into the insertion slot 9 on one side of the fixing column 5 of the next device. Then repeat the above operation to fix the subsequent connected anti-pressure plates 6. When the surface of the anti-pressure plate 6 is subjected to the impact force, the roller 7 on one side of the anti-pressure plate 6 will rotate under the action of the connecting shaft 8, and the surface of the roller 7 will rotate by being tangent to the impact force, thereby driving the front of the car to perform the correction operation, which can play the role of unloading the force.

[0027] When the collision force of a car is large, the roller 7 may bend. When the roller 7 bends, it cannot rotate to relieve the force. The bent roller 7 will cause the pressure plate 6 to bend inward. Since the pressure plate 6 is arc-shaped and one end of the pressure plate 6 is not fixed, when the device is subjected to an impact force from left to right, one end of the pressure plate 6 will drive the pressing block 3 and the connecting block 4 to slide to the right. This allows the pressing block 3 and the connecting block 4 to gradually extend into the insertion groove 9. At this time, the connection between adjacent pressure plates 6 will gradually increase with the magnitude of the impact force. By improving the correlation, the adjacent devices become a whole, improving the protection effect. At the same time, the pressing block 3 and the connecting block 4 can also transfer the impact force received by the previous pressure plate 6 to one end of the next adjacent pressure plate 6, further relieving the force.
