It also has a certain degree of anti-collision properties, which can reduce the damage caused by impact.

[0004] During the assembly of the overall guardrail, fasteners are required for fixation, which increases the installation steps. Furthermore, if the overall highway guardrail posts deform or separate from the ground due to vehicle collisions, they need to be re-laid and installed. The fastening bolts connecting to the ground are prone to breaking inside the holes or deforming and being difficult to separate, which affects the re-laying and installation work. Therefore, an innovative design is made based on the original structurally stable highway guardrail posts. Utility Model Content

[0005] The purpose of this utility model is to provide a structurally stable highway guardrail post to solve the problems mentioned in the background art. Currently, the commonly used structurally stable highway guardrail posts on the market require fasteners for fixing during the assembly of the entire guardrail, which increases the installation steps. Furthermore, when the entire highway guardrail post deforms or separates from the ground due to vehicle collisions, it needs to be re-laid and installed. The fastening bolts connecting to the ground are prone to breaking in the holes or deforming and not easily separating, which affects the re-laying and installation work.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a structurally stable high-speed guardrail post, comprising an embedded base plate and a combined base plate. The combined base plate is fixedly installed on the top surface of the embedded base plate, and the four corners of the combined base plate are provided with connecting slots and combined holes, with the combined holes located below the connecting slots. A combined frame is sleeved on the outer side of the combined base plate, and a connecting base plate is installed on top of the combined base plate, with through holes at the four corners of the connecting base plate. A guardrail arc-shaped post is welded and fixedly installed at the center of the top surface of the connecting base plate, and a combined block is welded and fixedly installed on the front surface of the guardrail arc-shaped post. A supporting guardrail post is installed on the outer side of the combined block, and an installation hole is provided in the center of the supporting guardrail post. A reinforcing post is installed inside the installation hole, and a guardrail sleeve is installed inside the installation hole, with the guardrail sleeve extending out of the installation hole.

[0007] Preferably, the through holes on the connecting base plate are aligned with the connecting hole grooves and the axis of the combination hole on the combined base plate, and the connection method between the connecting base plate and the combined frame is a sliding engagement.

[0008] Preferably, a regular hexagonal connector is installed above the connecting base plate, and a connecting post is provided at the center of the bottom surface of the regular hexagonal connector. The connecting post extends through the through hole into the interior of the connecting hole groove, and an anti-slip pad is sleeved on the outer side of the top of the connecting post. The anti-slip pad is located between the connecting base plate and the regular hexagonal connector. A combination connector is provided at the center of the bottom surface of the connecting post, and the combination connector is located inside the combination hole. A screw hole is opened at the center of the combination connector.

[0009] Preferably, the support guard post and the combination block are connected by embedding and fixing, and the support guard post and the reinforcing post are integrated into a single structure. Furthermore, the mounting hole and the reinforcing post are connected to the guardrail sleeve by snap-fit ​​embedding.

[0010] Preferably, the hexagonal connector and the connecting post are integrated into a single structure, the connecting post and the anti-slip pad are connected by a sliding connection, and the anti-slip pad is connected to the hexagonal connector and the connecting base plate by a compression fit.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the high-speed guardrail post with this structure is stable.

[0014] 1. The connection between the connecting base plate and the combined frame facilitates precise alignment of the through holes on the connecting base plate with the connecting slots on the combined base plate, which is beneficial for subsequent fixing work. At the same time, when the curved guardrail post is subjected to impact, the combination of the connecting base plate and the combined frame improves the impact resistance and reduces the phenomenon of the curved guardrail post flying out due to collision.

[0015] 2. The connecting base plate can be fixedly installed on top of the combined base plate through a regular hexagonal joint, connecting post, and combination joint for stable installation. This maintains the stability of the curved posts and guardrail sleeves during installation. In the event of an impact, if the impact force is too great and causes deformation of the curved posts, or damage and detachment of the connecting posts and combination joints connecting the base plate and the combined base plate, replacement is easy. If the combination joint separates from the connecting post due to an impact, the combination joint remains in the combination hole. It can be quickly disassembled through the screw hole in the center of the combination joint, avoiding the phenomenon of fasteners remaining in the groove and being difficult to separate.

[0023] 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.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a structurally stable high-speed guardrail post, including an embedded base plate 1 and a combined base plate 2. The combined base plate 2 is fixedly installed on the top surface of the embedded base plate 1, and the four corners of the combined base plate 2 are provided with connecting hole grooves 3 and combined holes 4, with the combined holes 4 located below the connecting hole grooves 3. A combined square frame 5 is sleeved on the outer side of the combined base plate 2, and a connecting base plate 6 is installed on the top of the combined base plate 2. The four corners of the connecting base plate 6 are provided with through holes 7. A guardrail arc-shaped post 8 is welded and fixedly installed at the center of the top surface of the connecting base plate 6, and a combined block 9 is welded and fixedly installed on the front surface of the guardrail arc-shaped post 8. A supporting guardrail post 10 is installed on the outer side of the combined block 9, and an installation hole 11 is provided in the center of the interior of the supporting guardrail post 10. A reinforcing post 12 is installed inside the installation hole 11, and a guardrail sleeve 13 is installed inside the installation hole 11, with the guardrail sleeve 13 extending out of the installation hole 11.

[0025] The through hole 7 on the connecting base plate 6 is aligned with the axis of the connecting hole groove 3 and the combination hole 4 on the combined base plate 2. The connection method between the connecting base plate 6 and the combined frame 5 is a sliding engagement. According to the docking of the connecting base plate 6 and the combined frame 5, the through hole 7 on the connecting base plate 6 can be precisely aligned with the connecting hole groove 3 and the combination hole 4 on the combined base plate 2, which facilitates subsequent fixed installation.

[0026] A hexagonal connector 14 is installed above the connecting base plate 6, and a connecting post 15 is provided at the center of the bottom surface of the hexagonal connector 14. The connecting post 15 extends through the through hole 7 and into the interior of the connecting hole groove 3. An anti-slip pad 16 is sleeved on the outer side of the top of the connecting post 15, and the anti-slip pad 16 is located between the connecting base plate 6 and the hexagonal connector 14. A combination connector 17 is provided at the center of the bottom surface of the connecting post 15, and the combination connector 17 is located inside the combination hole 4. A screw hole 18 is opened at the center of the combination connector 17. Subsequent fixing and installation work is carried out based on the hexagonal connector 14, the connecting post 15 and the combination connector 17.

[0027] The support post 10 and the combination block 9 are connected by embedding and fixing. The support post 10 and the reinforcing post 12 are integrated structures. The mounting hole 11 and the reinforcing post 12 are connected to the guardrail sleeve 13 by snap-fit ​​embedding. This makes it easy to combine and install the guardrail sleeve 13 and the support post 10 without fixing with bolts. The reinforcement post 12 also increases the firmness of the connection.

[0028] The hexagonal connector 14 and the connecting post 15 are integrated into one structure. The connection between the connecting post 15 and the anti-slip pad 16 is a sliding connection. The connection between the anti-slip pad 16, the hexagonal connector 14, and the connecting base plate 6 is a compression fit. The connecting post 15 can be installed through the hexagonal connector 14. The anti-slip pad 16 increases the stability after installation.

[0029] The connection method between the connecting post 15 and the through hole 7 and the connecting hole groove 3 is to embed and fix them. The diameter of the connecting post 15 is larger than the diameter of the combined hole 4. The connecting post 15 can pass through the through hole 7 and be combined with the connecting hole groove 3, thereby improving the stability of the subsequent connection and increasing the impact resistance.

[0030] The combination joint 17 is connected to the connecting post 15 by welding, and the combination joint 17 is connected to the combination hole 4 by thread. The combination joint 17 is assembled and fixed by threaded connection with the combination hole 4, which can fix the position of the connecting post 15 and the regular hexagonal joint 14.

[0031] Working principle: According to Figures 1 to 6First, the embedded base plate 1 and the combined base plate 2 can be placed at the roadside location. The combined base plate 2 is then fitted with the combined frame 5. Next, cement pouring or embedding into the road surface can be performed. Once the cement has hardened or the fixing is complete, the guardrail arc-shaped post 8 can be installed on top of the combined base plate 2 via the connecting base plate 6. The connecting base plate 6 and the combined frame 5 are slid in and engaged to achieve precise alignment, ensuring that the through hole 7 on the connecting base plate 6 aligns with the connecting groove 3 on the combined base plate 2. Then, the hexagonal connector 14 can be driven... The connecting post 15 and the combination joint 17 are assembled. The connecting post 15 slides through the through hole 7 into the connecting hole groove 3 for assembly. At the same time, the connecting post 15 drives the combination joint 17 to align with the combination hole 4 and rotate for threaded assembly and fixation. This causes the hexagonal joint 14 to press down the anti-slip pad 16, pressing the anti-slip pad 16 against the top surface of the connecting base plate 6, completing the fixed installation. Then, the guardrail sleeve 13 can be embedded and fixed through the central groove with the mounting holes 11 and reinforcing posts 12 on the supporting guardrail post 10. This process of laying and assembling is repeated sequentially. Subsequently, when the guardrail curved post 8 and guardrail sleeve 13 are deformed or tilted due to vehicle impact, and damage or deformation occurs at the connection between the guardrail curved post 8 and connecting base plate 6 and the combined frame 5 and combined base plate 2, the diameter of the connecting post 15 is larger than the diameter of the combined joint 17. Furthermore, the connecting post 15 fits tightly with the through hole 7 and the connecting hole groove 3, making it less prone to deformation and damage. However, the connection between the combined joint 17 and the combined hole 4 is more susceptible to damage and deformation. Since the diameter of the combined joint 17 is smaller than the diameter of the connecting post 15, the connection between the combined joint 17 and the connecting hole 4... The connecting posts 15 can break quickly due to excessive impact force, thus preventing deformation of the connection between the combined joint 17 and the combined hole 4 due to impact. Furthermore, the connecting posts 15 fit tightly with the through hole 7 and the connecting hole groove 3 to increase impact resistance. Subsequently, the combined joint 17 can be rotated and separated from the combined hole 4 through the screw hole 18. The overall assembly facilitates the subsequent reinstallation of the guardrail arc post 8 and the connecting base plate 6. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
