Description

Technical Field

[0001] This utility model relates to the technical field of guardrail connectors, specifically a crash barrier connector. Background Technology

[0002] Crash barriers are continuous structures made of corrugated steel guardrail panels spliced ​​together and supported by main posts. They use the deformation of the soil base, posts, and beams to absorb collision energy and force out-of-control vehicles to change direction and return to the normal driving direction, preventing vehicles from running off the road and protecting vehicles and passengers, thus reducing the losses caused by accidents. Anti-collision blocks are a type of connecting structure for highway guardrails and are used in the installation of highway guardrails.

[0003] When subjected to external forces, existing guardrail blocks cannot form an effective overall load-bearing system, reducing the overall impact and deformation resistance of the structure. Furthermore, they require drilling into the columns for connection, which damages the protective layer on the column surface and exposes the internal metal to the external environment. Under harsh conditions such as humidity and corrosive substances, the columns are prone to rust and corrosion, shortening their service life. Therefore, a new type of guardrail connector is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a crash barrier connector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a column, a first locking clamp slidably disposed on the surface of the column, a second locking clamp hinged to one side of the first locking clamp, an arc-shaped bonding plate connected to the surface of the first locking clamp, an anti-blocking block connected to the surface of the arc-shaped bonding plate, an inner lining layer connected to the inner circle of the anti-blocking block on the surface of the arc-shaped bonding plate, and both the anti-blocking block and the inner lining layer being polygonal, a connecting column connected to the center of the surface of the arc-shaped bonding plate, a reinforcing component connected to the corner of the inner circle of the inner lining layer, a buffer component slidably disposed on the surface of the connecting column inside the inner lining layer, connecting protrusions connected to the contact points of the first and second locking clamps, and two support rods connected to both sides of the surface of the first locking clamp, with the other ends of the two support rods penetrating the anti-blocking block and connected to the surface of the inner lining layer.

[0006] Preferably, the reinforcing component includes a first reinforcing plate connected to the corner of the inner ring of the inner lining layer, a second reinforcing plate connected to one side of the first reinforcing plate, and a plurality of triangular cross plates connected between the first and second reinforcing plates.

[0007] Preferably, the buffer assembly includes a first buffer plate and a second buffer plate slidably disposed on the surface of the connecting column, a buffer spring is connected between the first buffer plate and the second buffer plate at the central axis, and a plurality of damping telescopic rods are connected between the first buffer plate and the second buffer plate on one side of the buffer spring.

[0008] Preferably, one end of the connecting post penetrates the blocking block and the inner lining layer, and the surface outside the blocking block is threaded.

[0009] Preferably, a rubber pad is connected to one side of the anti-blocking block, and a through hole is opened on the surface of the rubber pad corresponding to the connecting column.

[0010] Preferably, a support block is provided at each corner between the anti-blocking block and the inner lining layer.

[0011] Preferably, the two connecting protrusions at the contact point of the first locking clamp and the second locking clamp are connected by bolts and nuts.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a reinforcing component at the corner of the inner ring of the inner lining layer, including a first reinforcing plate, a second reinforcing plate, and multiple triangular horizontal plates, the structural strength at the corner of the inner lining layer is effectively improved by utilizing the stability principle of triangles. This allows the entire structure to better disperse stress when subjected to external forces, reducing the risk of local deformation and damage, and improving the stability and reliability of the overall structure. The two connecting protrusions at the contact point of the first locking clamp and the second locking clamp are connected by bolts and nuts. This connection method is simple and easy to implement, facilitating disassembly and installation. It also reduces the need to drill holes in the column, preventing corrosion of the column by rust and extending the service life of the column. Attached Figure Description

[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 Figures 1-4 This utility model provides a technical solution, including a column 1, a first locking clamp 2 slidably disposed on the surface of the column 1, a second locking clamp 3 hinged to one side of the first locking clamp 2, an arc-shaped bonding plate 4 connected to the surface of the first locking clamp 2, an anti-blocking block 5 connected to the surface of the arc-shaped bonding plate 4, an inner lining layer 6 connected to the inner circle of the anti-blocking block 5 on the surface of the arc-shaped bonding plate 4, and both the anti-blocking block 5 and the inner lining layer 6 are polygonal, a connecting column 7 connected to the center of the surface of the arc-shaped bonding plate 4, a reinforcing component 8 connected to the corner of the inner circle of the inner lining layer 6, a buffer component 9 slidably disposed on the surface of the connecting column 7 inside the inner lining layer 6, a connecting protrusion 10 connected to the contact point of the first locking clamp 2 and the second locking clamp 3, and two support rods 11 connected to both sides of the surface of the first locking clamp 2, with the other end of the two support rods 11 penetrating through the anti-blocking block 5 and connected to the surface of the inner lining layer 6.

[0020] The reinforcing component 8 includes a first reinforcing plate 81 connected to the corner of the inner ring of the inner lining layer 6. A second reinforcing plate 82 is connected to one side of the first reinforcing plate 81. Multiple triangular cross plates 83 are connected between the first reinforcing plate 81 and the second reinforcing plate 82. Their function is to effectively disperse stress when the guardrail connector is subjected to external impact, preventing local overload from causing structural damage, thereby improving the impact resistance of the entire connector. Furthermore, the triangular cross plates 83 also increase the rigidity and overall strength of the inner lining layer 6, allowing the connector to better maintain its shape and stability during long-term use, thus extending its service life.

[0021] The buffer assembly 9 includes a first buffer plate 91 and a second buffer plate 92 slidably disposed on the surface of the connecting post 7. A buffer spring 93 is connected between the first buffer plate 91 and the second buffer plate 92 at their central axis. Multiple damping telescopic rods 94 are connected between the first buffer plate 91 and the second buffer plate 92 on one side of the buffer spring 93. Its function is to rapidly absorb and disperse the impact energy when the guardrail connector is impacted by an external force. The synergistic effect of the buffer spring 93 and the damping telescopic rods 94 allows the connector to undergo a certain degree of elastic deformation upon impact, thereby effectively reducing the impact force and protecting the guardrail and vehicle safety. Simultaneously, the damping telescopic rods 94 also increase the smoothness of the buffering process, reduce the impact force caused by sudden deformation, and further improve the anti-collision performance of the connector.

[0022] One end of the connecting post 7 passes through the anti-blocking block 5 and the inner lining layer 6, and the surface outside the anti-blocking block 5 is threaded. Its function is to facilitate the connection or fixation of the connecting post 7 to the guardrail plate, thereby increasing the flexibility and convenience of installation.

[0023] A rubber pad 12 is connected to one side of the anti-blocking block 5. A through hole 14 is opened on the surface of the rubber pad 12 corresponding to the connecting column 7. The function of the rubber pad 12 is to increase the friction and sealing between the anti-blocking block 5 and the column 1 or other connecting parts, preventing moisture, dust and other impurities from entering the connection and causing corrosion or loosening. At the same time, the elasticity of the rubber pad 12 can also play a certain buffering role, further enhancing the anti-collision performance of the connecting parts.

[0024] Support blocks 13 are installed at each corner between the anti-blocking block 5 and the inner lining layer 6. The function of the support blocks 13 is to enhance the structural connection between the anti-blocking block 5 and the inner lining layer 6, thereby improving the overall structural stability and load-bearing capacity. The support blocks 13 at each corner effectively disperse stress under external forces, preventing structural damage caused by localized stress concentration.

[0025] The two connecting protrusions 10 at the mating point of the first locking clamp 2 and the second locking clamp 3 are connected by bolts and nuts. This connection method is not only strong and reliable, but also facilitates installation and disassembly by workers, improving work efficiency. At the same time, the bolt and nut connection also facilitates later maintenance and replacement, reducing maintenance costs. During use, when it is necessary to disassemble the connecting parts, simply unscrewing the bolts and nuts easily separates the first locking clamp and the second locking clamp, making it convenient and quick.

[0026] Working principle: The first locking clamp 2 and the second locking clamp 3 fit tightly together and are fixed by bolts and nuts on the connecting convex plate 10, effectively preventing the guardrail connection from loosening or falling off due to impact. Simultaneously, the anti-blocking block 5 and the inner lining layer 6 on the arc-shaped bonding plate 4 absorb some of the impact energy, and through the synergistic effect of the reinforcing component 8 and the buffer component 9, further disperse and mitigate the impact force. The first reinforcing plate 81, the second reinforcing plate 82, and multiple triangular horizontal plates 83 in the reinforcing component 8 increase the structural strength of the inner lining layer 6, improving the impact resistance of the entire connection. Meanwhile, the first buffer plate 91, the second buffer plate 92, the buffer spring 93, and multiple damping telescopic rods 94 in the buffer component 9 can generate elastic deformation during impact, absorbing and dispersing impact energy, protecting the guardrail and vehicle safety. Furthermore, the threaded design of the connecting post 7 facilitates connection or fixation with the guardrail panel, increasing installation flexibility and convenience.
