Description

Technical Field

[0001] This utility model relates to the field of road guardrail technology, and in particular to a road guardrail that is easy to replace. Background Technology

[0002] As an important component of transportation infrastructure such as highways, expressways, and railways, road guardrails primarily serve to separate lanes, guide traffic flow, and prevent pedestrians and vehicles from crossing roads at will, playing a crucial role in ensuring road traffic order and safety.

[0003] However, in actual use, road guardrails are exposed to complex outdoor environments for a long time and face a variety of damage risks. On the one hand, traffic accidents are a common cause of guardrail damage, especially on road sections with high traffic volume and high speed. Once an accident occurs, the guardrail is prone to deformation, breakage and other problems. On the other hand, natural factors can cause the guardrail components to rust and age, affecting their structural stability and service life. In addition, human-caused damage can also cause partial failure of the guardrail.

[0004] When a guardrail is damaged and needs repair or replacement, the traditional guardrail uses bolts to connect the guardrail components to the support posts. This connection structure requires special tools such as wrenches to remove the bolts one by one during the replacement process. The operation is cumbersome, which not only consumes a lot of manpower and time, but also affects the efficiency of road traffic in sections with high traffic volume, and may even cause new traffic hazards.

[0005] Therefore, it is necessary to provide a road safety barrier that is easy to replace to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a road guardrail that is easy to replace, solving the problem of the cumbersome, time-consuming and labor-intensive replacement process of traditional road guardrails.

[0009] An isolation component is disposed between the two support columns. The isolation component includes multiple connecting components. Each of the two ends of the outer side of the multiple connecting components is fitted with a mounting frame. A snap-fit ​​plate is fixedly installed on the side of the mounting frame. A second magnetic plate is fixedly installed on the bottom of the snap-fit ​​plate. The snap-fit ​​plate snaps into the inner side of the snap-fit ​​groove. The second magnetic plate is magnetically attracted to the top of the first metal plate.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] First Embodiment

[0026] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a road guardrail that is easy to replace, provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the isolation component. Figure 3 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 3 The diagram shows a cross-sectional view of the mounting frame and connecting components. A replaceable road safety barrier includes: two support posts 1, with snap-fit ​​frames 2 fixedly installed on both sides of each of the two support posts 1; snap-fit ​​grooves 21 are provided on the sides of each of the four snap-fit ​​frames 2; and a first metal plate 3 is fixedly installed on the bottom of the inner side of each snap-fit ​​groove 21.

[0027] An isolation component 4 is disposed between the two support columns 1. The isolation component 4 includes multiple connecting components 41. Each of the two ends of the outer side of the multiple connecting components 41 is fitted with a mounting frame 42. A snap-fit ​​plate 45 is fixedly installed on the side of the mounting frame 42. A second magnetic plate 46 is fixedly installed on the bottom of the snap-fit ​​plate 45. The snap-fit ​​plate 45 snaps into the inner side of the snap-fit ​​groove 21. The second magnetic plate 46 is magnetically attracted to the top of the first metal plate 3.

[0028] Both sides of the support column 1 are equipped with snap-fit ​​frames 2, which makes it easy to install isolation components 4 on both sides of the support column 1 during subsequent use, so that multiple isolation components 4 can be connected through the support column 1 and snap-fit ​​frames 2.

[0029] Each of the multiple connecting components 41 has a second metal plate 43 fixedly installed at both ends, and a first magnetic plate 44 is magnetically attracted to the side of the second metal plate 43. The first magnetic plate 44 is fixedly installed on the inner side of the mounting frame 42.

[0030] After removing the isolation assembly 4 from between the two support columns 1, when it is necessary to replace the individual connecting assembly 41, the user only needs to move the two snap-fit ​​plates 45 in opposite directions to separate the first magnetic plate 44 and the second metal plate 43, thereby allowing multiple connecting assemblies 41 to be removed from between the two snap-fit ​​plates 45. At this time, the staff can replace the damaged connecting assembly 41 individually without replacing the entire isolation assembly 4, thus reducing maintenance costs.

[0031] The multiple connecting components 41 are arranged evenly from top to bottom.

[0032] The outer side of the snap-fit ​​plate 45 is attached to the inner side of the snap-fit ​​groove 21, and the outer side of the connecting component 41 is attached to the inner side of the mounting frame 42.

[0033] A base plate 5 is fixedly installed at the bottom of the support column 1.

[0034] Multiple through holes are provided inside the edge of the base plate 5. When in use, bolts are passed through the through holes and then installed on the ground to fix the base plate 5 in place.

[0035] The working principle of the road safety fence that is easy to replace provided by this utility model is as follows:

[0036] When installing the road guardrail, first fix the two support posts 1 to the preset position on the road using the base plate 5. Then, put the two ends of the connecting component 41 in the guardrail assembly 4 onto the mounting frame 42. At this time, the second metal plate 43 at both ends of the connecting component 41 will be magnetically connected to the first magnetic plate 44 on the inner side of the mounting frame 42, thus achieving the initial fixation of the connecting component 41 and the mounting frame 42. Next, align the snap-fit ​​plate 45 on the side of the mounting frame 42 with the snap-fit ​​groove 21 on the support post 1 and snap-fit ​​the snap-fit ​​plate 45 into the snap-fit ​​groove 21. The second magnetic plate 46 at the bottom of the snap-fit ​​plate 45 will be magnetically attracted to the first metal plate 3 in the snap-fit ​​groove 21, thereby fixing the guardrail assembly 4 between the two support posts 1 and completing the installation of the entire guardrail.

[0037] When the isolation component 4 is damaged and needs to be replaced, simply pull the snap plate 45 upward from the snap slot 21 to separate the second magnetic plate 46 from the first metal plate 3, and the entire isolation component 4 can be removed. Then, install the new isolation component 4 according to the above installation steps. No special tools are required, and the operation is simple and quick.

[0038] Compared with related technologies, the road guardrail that is easy to replace provided by this utility model has the following beneficial effects:

[0039] The isolation component 4 is disassembled by the cooperation of the support column 1, the snap-fit ​​frame 2, the snap-fit ​​groove 21, the first metal plate 3, and the isolation component 4. When the isolation component 4 needs to be disassembled, it is only necessary to lift the isolation component 4 upwards to separate the first metal plate 3 and the second magnetic plate 46, thereby removing the isolation component 4 from between the two support columns 1. In this way, the isolation component 4 and the support column 1 can be quickly disassembled and assembled without the need for special tools, which greatly simplifies the replacement operation and saves manpower and time costs. In addition, it also avoids affecting the efficiency of road traffic and causing new traffic hazards.

[0040] Second Embodiment

[0041] Please refer to the following: Figure 5 Based on the first embodiment of this application which provides a road safety barrier that is easy to replace, the second embodiment of this application proposes another road safety barrier that is also easy to replace. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0042] Specifically, the second embodiment of this application provides a road safety barrier that is easy to replace. The road safety barrier that is easy to replace includes a connecting assembly 41 comprising a fixing rod 411, both ends of the outer side of the fixing rod 411 being slidably connected to an extension rod 412, and the top of each of the two extension rods 412 being threadedly connected to a locking screw 413.

[0043] The bottom of the locking screw 413 abuts against the top of the fixing rod 411, and the outer side of the fixing rod 411 fits against the inner side of the extension rod 412.

[0044] The working principle of the road safety fence that is easy to replace provided by this utility model is as follows:

[0045] When the length of the guardrail needs to be adjusted according to the actual width of the road, loosen the locking screw 413 at the top of the extension rod 412 so that the bottom of the locking screw 413 separates from the top of the fixing rod 411. Then, pull the extension rod 412 so that it slides along the outer side of the fixing rod 411, thereby changing the overall length of the connecting assembly 41. After adjusting to the appropriate length, tighten the locking screw 413 so that the bottom of the locking screw 413 abuts against the top of the fixing rod 411, fixing the extension rod 412 and the fixing rod 411 together, thus completing the adjustment of the guardrail length.

[0046] Compared with related technologies, the road guardrail that is easy to replace provided by this utility model has the following beneficial effects:

[0047] The structure of fixing rod 411, extension rod 412 and locking screw 413 works together to make the length of connecting component 41 adjustable according to actual needs, so that the guardrail can adapt to roads of different widths, thus improving the versatility and practicality of the guardrail.
