Description

Technical Field

[0001] The utility model relates to the technical field of highway guardrail components, and more specifically, it relates to a highway safety guardrail component that is convenient for assembly. Background Art

[0002] In the context of the prior art, for highway safety guardrail components, there is a significant problem: they lack sufficient convenience during the installation and fixation process. This problem is not only limited to the complexity of the installation process itself, but also includes the cumbersome steps and procedures that must be followed to achieve the required stability and safety. As an indispensable safety facility on highways, the convenience of installing the safety guardrail directly affects the efficiency of maintenance and upgrading, and thus affects the safe operation of the entire highway system.

[0003] Firstly, the reason for this inconvenience may come from the limitations of the guardrail component design, which makes the connection between components require specific tools and technical operations. This not only increases the labor intensity of the staff, but also prolongs the total installation time. In addition, for complex terrains and different installation environments, such as curved areas, slope change areas, or areas with complex ground conditions, the existing guardrail components may be difficult to adapt to, thus requiring additional adjustments or customized solutions, which further increases the installation difficulty and cost.

[0004] Secondly, the inadequacy of the fixation mechanism is also an important factor affecting convenience. If the fixation mechanism is not reasonably designed and cannot quickly and firmly fix the guardrail component in the predetermined position, it will increase the difficulty of later maintenance, because this may cause the guardrail to loosen or displace during long-term use, thus reducing the safety of the highway. In addition, the inconvenient installation and fixation process also means that in case of an emergency, such as when it is necessary to quickly replace or repair a damaged guardrail, it may not be possible to complete it in time, thus exposing safety risks.

The sliding sleeve 17 is slidably connected to the top rod 12, and a plurality of rubber blocks 18 are equidistantly arranged on the side wall of the sliding sleeve 17. A plurality of rubber blocks 18 are stuck on the inner wall of the telescopic hole 13. A synchronous groove 19 is formed on the intermediate sleeve 6, and the hexagonal sleeve 9 is clamped in the synchronous groove 19.

[0031] In this embodiment, when fixing, since the guardrail body 1 is installed on the vertical plate 2, when it needs to be fixed, the external plate 3 is fixedly installed on the external road surface, so the threaded rod 5 and the positioning rod 20 are fixed accordingly, and then the bottom plate 4 passes through the threaded rod 5 and the positioning rod 20 respectively to fit on the external plate 3, and then the intermediate sleeve 6 is slidably connected to the threaded rod 5. At this time, the fitting sleeve 8 is not connected to the intermediate sleeve 6, so the multiple interference rods 14 can be extended and retracted along the telescopic hole 13, so it is not necessary to rotate downward along the thread groove during installation. , so it can be conveniently fixed. When it is moved to the corresponding position, the fitting sleeve 8 is slidably connected to the intermediate sleeve 6, and the hexagonal sleeve 9 is stuck in the synchronous groove 19.

Then, the middle sleeve 6 is slidably connected to the threaded rod 5. At this time, the fitting sleeve 8 is not connected to the middle sleeve 6. Therefore, the plurality of abutting rods 14 can expand and contract along the telescopic holes 13. Therefore, during installation, there is no need to rotate downward along the thread groove. Therefore, it can be conveniently fixed. When it is moved to the corresponding position, the fitting sleeve 8 is slidably connected to the middle sleeve 6, and at the same time, the hexagonal sleeve 9 is stuck on the synchronous groove 19. At this time, the ejector rod 12 abuts against the inner wall of the fitting sleeve 8. Therefore, the abutting rod 14 is in a fixed state, so that the abutting rod 14 can only be stuck in the spiral groove 15. Then, the hexagonal sleeve 9 is stuck on the synchronous groove 19, and it is fixed by driving it with a wrench. The plurality of middle sleeves 6 respectively repeat the above operations.

Therefore, the plurality of hexagonal sleeves 9 can be synchronously fixed, and thus the fixation process is completed.
