A shock-absorbing and reinforcement device for anti-collision posts

Abstract

This utility model provides a crash barrier buffer and shock absorption reinforcement device, relating to the technical field of traffic safety protection facilities. It includes a base, on the upper surface of which the crash barrier body is fixedly mounted. A mounting hole is provided through the surface of the base. This utility model utilizes a structure where an I-shaped block and an I-shaped groove slide together on the side of the crash barrier body. A fixing bolt and a fixing screw hole are threadedly connected, allowing for quick assembly and disassembly of the buffer sleeve assembly. When a vehicle collides, the crash barrier plate is subjected to force, pushing the buffer rod to slide within the buffer sleeve. This causes a limiting block to compress the buffer spring. The buffer spring absorbs the impact energy, reducing the impact force on the crash barrier body and the vehicle. Furthermore, the sliding cooperation between the limiting block, the sliding rod, and the buffer sleeve ensures stability during the buffering process, improving the crash barrier's buffering and shock absorption performance. Additionally, a protective pad made of natural rubber is provided on the side of the crash barrier plate for further buffering during impact, reducing damage to the vehicle's surface.

Description

Technical Field

[0001] This utility model relates to the technical field of traffic safety protection facilities, and in particular to a shock-absorbing and reinforcement device for anti-collision posts. Background Technology

[0002] Traffic safety protection facilities are an important component of modern transportation systems to ensure public safety. Bollards, as key facilities within these facilities, play a crucial role in isolating roads, restricting vehicle traffic, and preventing accidental collisions. In real-world scenarios, when a vehicle collides with a bollard due to loss of control, misoperation, or other reasons, the bollard must effectively absorb the impact energy to reduce the severity of the accident.

[0003] In existing technologies, traditional crash barriers are mostly installed using a rigid fixing method, lacking an effective buffer and energy absorption design. When a vehicle collides, the impact force acts directly on the crash barrier body and is transmitted to the ground foundation through the base. This can easily cause the crash barrier to deform, break, or even collapse as a whole, which not only affects its secondary use performance but may also cause serious traffic accidents, thus requiring improvement. Utility Model Content

[0004] The purpose of this invention is to solve the problems of poor buffering performance and weak impact resistance in the existing technology, and to propose a shock-absorbing and strengthening device for anti-collision pillars.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a crash barrier buffer and shock absorption reinforcement device, comprising a base, a crash barrier body fixedly installed on the upper surface of the base, an installation hole through the surface of the base, an I-shaped block on the side of the crash barrier body, a buffer sleeve fixedly installed on the side of the I-shaped block, a buffer rod slidably connected inside the buffer sleeve, a crash barrier plate fixedly installed at one end of the buffer rod, a limit block fixedly installed at one end of the buffer rod, a sliding rod fixedly installed inside the buffer sleeve, a buffer spring sleeved on the surface of the sliding rod, an I-shaped groove on the side of the crash barrier body, a fixing screw hole on the surface of the I-shaped block, a fixing bolt threaded inside the crash barrier body, and a warning strip on the side of the crash barrier body.

[0006] Preferably, the side of the anti-collision plate is provided with a protective pad, and the protective pad is made of natural rubber.

[0007] Preferably, the limiting block and the buffer sleeve are slidably connected.

[0008] Preferably, the limiting block and the sliding rod are slidably connected.

[0009] Preferably, one end of the buffer spring is fixedly connected to the side of the limiting block, and the other end of the buffer spring is fixedly connected to the inner side of the buffer sleeve.

[0010] Preferably, the I-shaped block and the I-shaped groove are slidably connected.

[0011] Preferably, the fixing bolt is threadedly connected to the fixing screw hole.

[0012] Preferably, a locking block is fixedly connected to the side of the warning strip, a locking groove is opened on the side of the anti-collision post body, a magnet A is fixedly installed on the side of the warning strip, and a magnet B is fixedly installed on the side of the anti-collision post body.

[0013] Preferably, the card block and the card slot are engaged and connected, and there are two sets of card blocks and card slots located at both ends of the warning strip.

[0014] Preferably, magnet A and magnet B are attracted to each other.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, by setting an I-shaped block and an I-shaped groove slidingly on the side of the anti-collision post body, and using a fixing bolt and a fixing screw hole for threaded connection, the buffer sleeve assembly can be quickly disassembled and assembled. When a vehicle crashes, the anti-collision plate is pushed by the force to slide the buffer rod in the buffer sleeve, which drives the limiting block to compress the buffer spring. The buffer spring absorbs the impact energy and reduces the impact force on the anti-collision post body and the vehicle. Moreover, the sliding cooperation between the limiting block, the sliding rod, and the buffer sleeve ensures the stability of the buffering process and improves the buffering and shock absorption performance of the anti-collision post. In addition, a protective pad made of natural rubber is set on the side of the anti-collision plate, which can further buffer during the impact and reduce the damage to the vehicle surface.

[0017] 2. In this utility model, by setting a detachable warning strip on the body of the anti-collision post, the warning strip is connected by a card block and a card slot, and is fixed by the adsorption of magnet A and magnet B, so that the warning strip is quick to install and easy to replace, and has good stability and nighttime reflective warning effect, thereby improving the safety warning capability of the anti-collision post.

Detailed Implementation

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1: As Figures 1-6As shown, this utility model provides a technical solution: a shock-absorbing and reinforcing device for anti-collision posts, including a base 1, an anti-collision post body 2 fixedly installed on the upper surface of the base 1, an installation hole 3 through the surface of the base 1, an I-shaped block 4 on the side of the anti-collision post body 2, a buffer sleeve 5 fixedly installed on the side of the I-shaped block 4, a buffer rod 6 slidably connected inside the buffer sleeve 5, an anti-collision plate 7 fixedly installed at one end of the buffer rod 6, a limit block 9 fixedly installed at one end of the buffer rod 6, a sliding rod 10 fixedly installed inside the buffer sleeve 5, a buffer spring 11 sleeved on the surface of the sliding rod 10, and an installation hole 3 through the surface of the anti-collision post body 2. The I-shaped groove 12 and the I-shaped block 4 have fixed screw holes 13 on their surfaces. The anti-collision post body 2 is internally threaded with a fixing bolt 14. The side of the anti-collision post body 2 is provided with a warning strip 15. The side of the anti-collision plate 7 is provided with a protective pad 8. The protective pad 8 is made of natural rubber. The limiting block 9 is slidably connected to the buffer sleeve 5. The limiting block 9 is slidably connected to the slide rod 10. One end of the buffer spring 11 is fixedly connected to the side of the limiting block 9. The other side of the buffer spring 11 is fixedly connected to the inner side of the buffer sleeve 5. The I-shaped block 4 is slidably connected to the I-shaped groove 12. The fixing bolt 14 is threadedly connected to the fixing screw hole 13.

[0028] In this embodiment, when a vehicle collides with a crash barrier, the crash barrier 7 bears the brunt of the impact. The natural rubber protective pad 8 on its side can initially buffer the impact force with its good elasticity, reducing the rigid contact between the vehicle and the crash barrier 7 and reducing the degree of damage to the vehicle. At the same time, after the crash barrier 7 is subjected to force, it drives the buffer rod 6 to slide inside the buffer sleeve 5. The limiting block 9 moves accordingly and compresses the buffer spring 11. The buffer spring 11 undergoes elastic deformation, converting the kinetic energy generated by the impact into elastic potential energy, further absorbing and dissipating the impact energy, and slowing down the transmission of the impact force to the crash barrier body 2, thus achieving a good buffering and shock absorption effect and effectively protecting the structural integrity of the crash barrier body 2. In addition, the sliding fit between the I-shaped block 4 and the I-shaped groove 12, combined with the threaded connection between the fixing bolt 14 and the fixing screw hole 13, makes the installation and disassembly of the buffer sleeve 5 assembly convenient, facilitating the later inspection and replacement of components such as the buffer spring 11 and the buffer rod 6.

[0029] Example 2: Figures 1-6 As shown, a locking block 16 is fixedly connected to the side of the warning strip 15, a locking groove 17 is opened on the side of the anti-collision post body 2, a magnet A18 is fixedly installed on the side of the warning strip 15, a magnet B19 is fixedly installed on the side of the anti-collision post body 2, the locking block 16 and the locking groove 17 are engaged and connected, there are two sets of locking blocks 16 and locking grooves 17, and they are located at both ends of the warning strip 15, and the magnet A18 and the magnet B19 are attracted to each other.

[0030] In this embodiment, the warning strip 15 engages with the slots 17 on the side of the bollard body 2 via the locking blocks 16 at both ends, which can quickly position and initially fix the warning strip 15, ensuring its accurate installation position. At the same time, the magnet A18 on the side of the warning strip 15 and the magnet B19 on the side of the bollard body 2 attract each other, further enhancing the fixing effect of the warning strip 15 and making it less likely to fall off under the influence of external environmental factors. This double fixing structure not only facilitates quick disassembly and replacement of the warning strip 15 when it is damaged or faded, ensuring that the warning function is always effective, but also reminds passing vehicles to pay attention and avoid it through the conspicuous warning strip 15, improving the level of road safety protection. Moreover, the installation method is simple, requiring no additional complicated tools, reducing maintenance costs and difficulties.

[0031] The working principle of this embodiment is as follows: When installing the anti-collision post buffer and shock absorption reinforcement device, firstly, the base 1 is fixed to the ground position to be protected by bolts through the mounting holes 3 on the surface. Then, the buffer sleeve 5 assembly on the side of the I-shaped block 4 is aligned with the I-shaped groove 12 on the side of the anti-collision post body 2, and the I-shaped block 4 is pushed to slide into the I-shaped groove 12. Then, the fixing bolt 14 is passed through the anti-collision post body 2 and screwed into the fixing screw hole 13 on the surface of the I-shaped block 4 to tighten it, thus completing the installation of the buffer sleeve 5 assembly. Next, the locking blocks 16 at both ends of the warning strip 15 are aligned with the locking grooves 17 on the side of the anti-collision post body 2 and inserted into engagement. At the same time, the magnet A18 on the side of the warning strip 15 and the magnet B19 on the side of the anti-collision post body 2 attract each other to ensure that the warning strip 15 is firmly installed on the side of the anti-collision post body 2. When the vehicle is involved in a collision, the impact force first acts on the anti-collision plate 7. The anti-collision plate 7 is impacted and pushes the buffer rod 6 to slide inside the buffer sleeve 5, while simultaneously driving the limiter. Block 9 slides along the slide bar 10 and compresses the buffer spring 11. During the compression process, the buffer spring 11 absorbs a large amount of impact energy, effectively reducing the impact force on the anti-collision post body 2 and the vehicle. In addition, the natural rubber protective pad 8 set on the side of the anti-collision plate 7 further buffers the impact force, reduces vehicle surface damage, and reduces noise. After the impact, the buffer spring 11 automatically extends due to its own elasticity, pushing the limit block 9 back to its original position along the slide bar 10, thereby restoring the buffer bar 6 and the anti-collision plate 7 to their initial positions, ready to deal with the next possible impact. In addition, the warning strip 15 is engaged with the slot 17 on the anti-collision post body 2 by the locking block 16 fixed on its side, and the stability is enhanced by the attraction between magnet A18 and magnet B19. When it is necessary to replace or maintain the warning strip 15, it is only necessary to overcome the attraction between the magnets and pull the locking block 16 out of the slot 17 to complete the disassembly. The replacement process is simple and quick and does not require the use of tools.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
