Description

Technical Field

[0001] The utility model relates to the technical field of highway guardrails, in particular to a clip-on highway guardrail. Background Art

[0002] Highway guardrails are a commonly used tool in municipal engineering. Highway guardrails are generally set in the middle of the highway. First, they can divert vehicles traveling in opposite directions to avoid vehicle collisions. Second, they can prevent pedestrians from crossing the road and reduce the occurrence of traffic accidents. Therefore, the role of highway guardrails in municipal engineering is very important.

[0003] At present, the existing highway guardrail (such as patent publication number: CN220057747U) discloses a highway guardrail. By setting a lifting barrier structure on the guardrail, when the guardrail is transported and stored, the lifting barrier structure is kept in a stowed state, which does not cause inconvenience in transportation and storage. When the guardrail is installed, the lifting barrier structure can be extended to increase the overall height of the guardrail, making the effect of the guardrail in blocking pedestrians more intuitive and effective, thereby reducing the probability of traffic accidents.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems: the guardrail was installed by inserting one end of the guardrail into the base, but there was no mechanism for locking the two guardrails to each other. When impacted by external forces, the guardrail was prone to shaking, and the two guardrails were prone to friction and dislocation, resulting in a low overall firmness of the guardrail. Utility Model Content

[0005] (1) Technical problems solved

[0006] In response to the shortcomings of the existing technology, the utility model provides a snap-on highway guardrail, which solves the technical problem that only relying on the base to connect two guardrails will result in a certain distance between the guardrails. This distance allows the guardrails to swing freely inside the base, thereby affecting the firmness of the guardrail.

[0007] (2) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A clip-on highway guardrail comprises two guardrail bodies and a clip seat, wherein the two side ends of each guardrail body are fixedly installed with a first positioning block, the side ends of each guardrail body are provided with two first clip slots, the two side ends of each guardrail body are provided with a second clip slot, and the two side ends of each guardrail body are slidably installed with a fixing plate.

[0010] Preferably: a second positioning block is fixedly installed on the inner side of each of the fixed plates, a spring rod is fixedly installed on the inner side of each of the fixed plates, a pull ring is fixedly installed on the outer side of each of the fixed plates, and limiting blocks are slidably installed on both side ends of each of the first positioning blocks. The side ends of the two limiting blocks are fixedly installed with the same buffer rod, and the two first positioning blocks are staggeredly installed on the side ends of the guardrail body and are respectively aligned with the inside of the first slot, and two grooves are further provided inside the first slot.

[0011] (3) Beneficial effects

[0012] 1. By allowing the top end of the limit block to engage with the inner side wall of the first slot, while the guardrail bodies are docked, the side end of the guardrail body slides and rubs against the second positioning block. Since one side of the second positioning block is an arc-shaped design, the two guardrail bodies are docked, and the guardrail body automatically squeezes the second positioning block to move, allowing the second positioning block to slide outward, and the fixing plate slides on the side end of the guardrail body, pulling the spring rod to retract. When the guardrail body is fitted and fixed, under the reverse force of the spring rod, the spring rod pulls the fixing plate to move toward the side end of the guardrail body, allowing the fixing plate to drive the second positioning block to be clamped into the inside of the second slot. By clamping and fixing the two guardrail bodies, the stability between the guardrail bodies is increased to prevent shaking during use.

[0013] 2. By pulling the spring rod to extend and retract the side end of the guardrail body, the fixed plate drives the second positioning block inside the second slot, so that the second positioning block leaves the side end of the other guardrail body. By pushing and pulling horizontally, a thrust is applied to one of the guardrail bodies to disconnect the two guardrail bodies. The guardrail body drives the first positioning block to drive the inside of the first slot, so that the first positioning block drives the limit block to rub inside the first slot and disconnect. The guardrail body can be quickly disassembled and replaced for easy maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The embodiment of the present application provides a snap-on highway guardrail, which effectively solves the problem that only relying on a base to connect two guardrails will result in a certain distance between the guardrails. This distance allows the guardrails to swing freely inside the base, thereby affecting the firmness of the guardrail. By allowing the top end of the limit block to engage the inner wall of the first slot, and at the same time, during the process of docking the guardrail bodies, the side end of the guardrail body slides and rubs against the second positioning block. Since one side of the second positioning block is an arc-shaped design, when the two guardrail bodies are docked, the guardrail body automatically squeezes the second positioning block to move, allowing the second positioning block to slide outward, and the fixing plate slides on the side end of the guardrail body, pulling the spring rod to retract and retract. After the guardrail body is fitted and fixed, under the reverse force of the spring rod, the spring rod pulls the fixing plate toward the side end of the guardrail body, allowing the fixing plate to drive the second positioning block to be clamped into the inside of the second slot. By clamping and fixing the two guardrail bodies, the stability between the guardrail bodies is increased and shaking during use is prevented.

[0021] Example

[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that when two guardrails are connected only by the base, there will be a certain distance between the guardrails. This distance allows the guardrails to swing freely inside the base, thereby affecting the firmness of the guardrails. The overall idea is as follows:

[0023] The two sides of the two guardrail bodies 11 are fixedly mounted with a first positioning block 13, and the two side ends of each guardrail body 11 are provided with two first card slots 14. The two side ends of each guardrail body 11 are provided with a second card slot 22. The two side ends of each guardrail body 11 are slidably mounted with a fixing plate 16. The side ends of the two guardrail bodies 11 are first aligned. Since the first positioning blocks 13 and the first card slots 14 are staggered at the side ends of the guardrail bodies 11, the guardrail bodies 11 are moved to align the first positioning blocks 13 and the first card slots 14 with each other. During the process of aligning and fitting the two guardrail bodies 11, the two side ends of the first card slot 14 squeeze the top of the limit block 17. Due to the arc-shaped design of the top of the limit block 17, the top of the limit block 17 is squeezed and slides against each other to squeeze the top of the buffer rod 18, forcing the limit block 17 to enter the interior of the first positioning block 13.

[0024] The inner side of each fixing plate 16 is fixedly installed with a second positioning block 19, the inner side of each fixing plate 16 is fixedly installed with a spring rod 21, the outer side of each fixing plate 16 is fixedly installed with a pull ring 15, the two side ends of each first positioning block 13 are slidably installed with a limit block 17, and the side ends of the two limit blocks 17 are fixedly installed with the same buffer rod 18. The two guardrail bodies 11 are docked, and the guardrail bodies 11 automatically squeeze the second positioning block 19 to move, allowing the second positioning block 19 to slide outward, and the fixing plate 16 slides at the side end of the guardrail body 11, pulling the spring rod 21 to retract and retract. When the guardrail body 11 is fitted and fixed, under the reverse force of the spring rod 21, the spring rod 21 pulls the fixing plate 16 to move toward the side end of the guardrail body 11, allowing the fixing plate 16 to drive the second positioning block 19 to be clamped into the interior of the second slot 22. The two first positioning blocks 13 are staggered at the side end of the guardrail body 11 and are respectively aligned with the interior of the first slot 14. Two grooves are also provided inside the first slot 14.

[0025] Working principle:

[0026] The first step is to align the side ends of the two guardrail bodies 11 during installation. Since the first positioning block 13 and the first slot 14 are installed alternately on the side ends of the guardrail body 11, move the guardrail body 11 to align the first positioning block 13 with the first slot 14. During the alignment and fitting of the two guardrail bodies 11, the two side ends of the first slot 14 squeeze the top of the limit block 17. Due to the arc-shaped design of the top of the limit block 17, the top of the limit block 17 is squeezed and slides against each other to squeeze the top of the buffer rod 18, forcing the limit block 17 to enter the interior of the first positioning block 13. When the two guardrail bodies 11 are fitted together, under the reverse force of the two buffer rods 18, the buffer rod 18 pops out of the limit block 17, allowing the top of the limit block 17 to engage the inner side wall of the first slot 14. At the same time, during the docking process of the guardrail bodies 11, the guardrail The side end of the guardrail body 11 slides and rubs with the second positioning block 19. Since one side of the second positioning block 19 is an arc-shaped design, the two guardrail bodies 11 are docked, and the guardrail body 11 automatically squeezes the second positioning block 19 to move, allowing the second positioning block 19 to slide outward, and the fixing plate 16 slides on the side end of the guardrail body 11, pulling the spring rod 21 to retract and retract. When the guardrail body 11 is fitted and fixed, under the reverse force of the spring rod 21, the spring rod 21 pulls the fixing plate 16 to move toward the side end of the guardrail body 11, allowing the fixing plate 16 to drive the second positioning block 19 to be stuck into the inside of the second slot 22. One side of the second positioning block 19 fits with the inner wall of the second slot 22. Through the second positioning block 19 and the first positioning block 13, the guardrail body 11 is restricted and fixed using two structures, thereby increasing the stability between the guardrail bodies 11.

[0027] In the second step, the guardrail body 11 can be pulled to disconnect the guardrail body 11 from the card seat 12 first, and the pull ring 15 can be pulled to drive the fixed plate 16 to slide, and the fixed plate 16 is away from the side end of the guardrail body 11. The sliding of the fixed plate 16 pulls the spring rod 21 to retract at the side end of the guardrail body 11. At the same time, the fixed plate 16 drives the second positioning block 19 inside the second card slot 22, so that the second positioning block 19 leaves the side end of the other guardrail body 11, and pushes and pulls horizontally to adjust the position of the guardrail body 11. One guardrail body 11 applies a thrust to disconnect the two guardrail bodies 11. The guardrail body 11 drives the first positioning block 13 to drive the inside of the first slot 14, and the first positioning block 13 drives the limit block 17 to rub inside the first slot 14. The inner wall of the first slot 14 squeezes the limit block 17, forcing the limit block 17 to slide into the inside of the first positioning block 13, so that the two first positioning blocks 13 are disconnected from the first slot 14, which makes it easy to disconnect the two guardrail bodies 11 and disassemble the guardrail bodies 11.

[0028] Finally, it should be noted that the above embodiments are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
