Abstract
Description
Technical Field
[0001] This utility model relates to the field of highway protection technology, and in particular to a highway guardrail post. Background Technology
[0002] Highway protection refers to a series of engineering measures and management methods adopted to ensure the normal use of highways and their ancillary facilities, extend their service life, and ensure traffic safety and smooth flow, in response to threats from natural factors (such as climate and geology) and human factors (such as traffic accident collisions) faced by highways. Among these, highway guardrails are a widely used and effective means of highway protection.
[0003] Currently, highway guardrails are designed to align with the road's direction. When a vehicle collides with a guardrail, the guardrail's shape and installation angle exert a lateral force on the vehicle, guiding it to travel along the guardrail's direction, gradually slowing it down and bringing it to a stop. This prevents the vehicle from running off the road or colliding with oncoming vehicles. However, existing highway guardrails often use a single model with no height adjustment. In low-lying areas, guardrails are ineffective in preventing vehicles from running off the road, while in high-lying areas, they can create visual pressure on drivers, affecting driving safety and leading to highway accidents. Utility Model Content

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] Reference Figures 1-3 An embodiment of this utility model provides: a highway guardrail post, including a base 1, a receiving box 2 fixedly connected to the upper surface of the base 1, a post body 3 provided on the inner wall of the receiving box 2, a fixing block 4 fixedly connected to the outer wall of the receiving box 2, a rotating component provided on the outer wall of the fixing block 4, a slider 7 connected to the rotating component, the rotating component being used to drive the slider 7 to slide, a connecting component being provided on the outer wall of the slider 7, the connecting component being used to connect the receiving box 2 and the post body 3, the connecting component being connected to the receiving box 2, the connecting component being connected to the post body 3, a slot 10 being opened inside the post body 3, and the outer wall of the slider 7 being slidably connected to the inner wall of the receiving box 2;
[0026] Specifically, by pressing down the rotating component, the slider 7 slides inside the receiving box 2. The fixing block 4 provides a fulcrum for the rotating component and keeps it stable during movement. Since the slider 7 is connected to the connecting component, the connecting component slides inside the column body 3 under the action of the slider 7. Then, the connecting component is pulled out from the slot 10 and enters the receiving box 2. At this time, the column body 3 is pulled to slide inside the receiving box 2, adjusting the column body 3 to the specified height. The connecting component is then re-inserted into the new slot 10, connecting the receiving box 2 and the column body 3. This allows for flexible adjustment of the height of the column body 3 according to the deployment location and environment of the highway guardrail, enabling the highway guardrail to perform its safety protection function in different scenarios and improving the overall safety and adaptability of the highway.
[0027] Reference Figure 3 The rotating assembly includes a handle 5, the inner wall of which is rotatably connected to the outer wall of the fixed block 4, and a transmission block 6 is fixedly connected to the outer wall of the handle 5. The outer wall of the transmission block 6 is disposed on the inner wall of the slider 7.
[0028] Specifically, by pressing down the throttle 5, since the throttle 5 is fixedly connected to the transmission block 6, the transmission block 6 rotates synchronously under the drive of the throttle 5, and then the slider 7 slides inside the receiving box 2 under the drive of the transmission block 6.
[0029] Reference Figure 2 and Figure 3 The connecting component includes a second slider 8, the outer wall of which is fixedly connected to the outer wall of the first slider 7. A return spring 9 is provided on the outer wall of the second slider 8, and the outer wall of the return spring 9 is provided on the inner wall of the receiving box 2.
[0030] Specifically, since slider 28 is fixedly connected to slider 17, slider 28 slides inside the column body 3 under the action of slider 17. Then slider 28 detaches from the inside of the column body 3 and slides into the inside of the receiving box 2. During this process, since the return spring 9 is fixedly connected to slider 28, the return spring 9 undergoes elastic deformation under the action of slider 28. The return spring 9 is used for the subsequent reset of slider 28.
[0031] Reference Figure 2 The right outer wall of slider 2 8 is slidably connected to the inner wall of column body 3, and the left outer wall of slider 2 slidably connected to the inner wall of receiving box 2. The outer wall of slider 2 8 is set inside the slot 10.
[0032] Specifically, the container 2 is connected to the column body 3 by the slider 2 8, thereby fixing the column body 3 at a specified height.
[0033] Reference Figure 4 and Figure 5The outer wall of the container 2 is fixedly connected to a positioning block 11, the outer wall of the positioning block 11 is rotatably connected to a rotating block 12, the outer wall of the rotating block 12 is fixedly connected to a connecting rod 14, the outer wall of the connecting rod 14 is provided with a sealing assembly, the sealing assembly is connected to a rotating block 18, the upper surface of the base 1 is provided with a limit assembly, and the sealing assembly is connected to the limit assembly; the sealing assembly includes a housing 13, the inner wall of the housing 13 is slidably connected to the outer wall of the connecting rod 14, the outer wall of the connecting rod 14 is fixedly connected to a slider 15, the inner wall of the housing 13 is provided with an air chamber 16; the slider 15 is slidably connected to the inside of the housing 13 through the air chamber 16; the limit assembly includes a positioning block 17, the lower surface of the positioning block 17 is fixedly connected to the upper surface of the base 1, the outer wall of the positioning block 17 is rotatably connected to a rotating block 18, and the outer wall of the rotating block 18 is fixedly connected to the outer wall of the housing 13;
[0034] Specifically, after the column body 3 withstands external impact, the column body 3 causes the receiving box 2 to tilt. At this time, the rotating block 12 rotates around the positioning block 11 under the drive of the receiving box 2. Then, the connecting rod 14 rotates around the positioning block 11 under the drive of the rotating block 12. Subsequently, the outer shell 13 rotates synchronously under the drive of the connecting rod 14. Then, the rotating block 2 18 rotates around the positioning block 2 17 under the drive of the outer shell 13. At the same time, the slider 3 15 slides inside the air chamber 16 under the drive of the connecting rod 14. At this time, the slider 3 15 compresses the gas inside the air chamber 16. While compressing the gas, it assists the column body 3 in relieving the impact. When the impact ends, the compressed gas inside the air chamber 16 slowly pushes the slider 3 15 back to its original position. This can achieve the effect of providing support for the column body 3, relieving the impact, and preventing the column body 3 from tipping over under impact.
[0035] Working principle: Pressing down the throttle 5 drives the transmission block 6 to rotate synchronously. Then, the slider 1 7 slides under the drive of the transmission block 6, and then the slider 2 8 slides under the drive of the slider 1 7. Then, the slider 2 8 slides into the interior of the receiving box 2. At the same time, the return spring 9 undergoes elastic deformation under the drive of the slider 2 8. The return spring 9 is used to reset the slider 2 8. At this time, the slider 2 8 connects the receiving box 2 to the column body 3. Thus, the height of the column body 3 can be flexibly adjusted according to the specific deployment location of the highway guardrail and the surrounding environmental factors. The highway guardrail can play its safety protection function and improve the overall safety of the highway.
[0036] After the column body 3 withstands the external impact, the receiving box 2 tilts, and then the rotating block 12 rotates under the drive of the receiving box 2. Subsequently, the connecting rod 14 rotates under the drive of the rotating block 12, and then the outer shell 13 rotates synchronously under the drive of the connecting rod 14. Then the rotating block 2 18 rotates under the drive of the outer shell 13. After that, the slider 3 15 slides under the drive of the connecting rod 14. Then the slider 3 15 compresses the gas inside the air chamber 16. While compressing the gas, it also helps the column body 3 to relieve the impact. When the impact ends, the compressed gas inside the air chamber 16 slowly pushes the slider 3 15 to return to its original position. This can achieve the effect of providing support for the column body 3, relieving the impact, and preventing the column body 3 from tilting or shifting significantly under impact.
