Description

Technical Field

[0001] This application relates to the field of guardrail technology, specifically a municipal guardrail. Background Technology

[0002] Municipal guardrails are protective barriers in the middle of highways, installed to prevent pedestrians and vehicles from crossing the road at will in violation of traffic rules, and to provide safety for pedestrians and vehicles.

[0003] An existing patent (publication number: CN222251859U) discloses a municipal guardrail device, including a base. A limiting opening is formed at the top of the base, and a connecting post is inserted into the limiting opening. A railing is movably mounted on the inner side wall of the connecting post, and a limiting hole is formed on the inner side wall of the connecting post. The inner wall of the limiting hole is provided with an internal thread. Connecting rods are provided at both ends of the railing, and the outer wall of the connecting rods is provided with external threads. The base is divided into two groups: a rod is fixedly connected to the left side of the left base, and a insertion hole is formed on the right side of the right base. This utility model, through the setting of limiting holes, limiting openings, and connecting rods, divides the entire guardrail into multiple components that can be flexibly assembled and disassembled, minimizing space occupation during transportation. The addition of counterweights, reflective strips, lighting, storage boxes, and fire extinguishers increases the stability of the guardrail and improves its visibility at night. Furthermore, it allows for quick access to fire extinguishers in case of fire near the road, enhancing the functionality of the guardrail.

[0004] While the device in the aforementioned comparative documents is easy to transport, it can only be installed in a straight, strip-like shape, which makes it difficult to meet the installation requirements under different road conditions. To solve the above problem, a municipal guardrail is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a municipal guardrail that, through the cooperation of adjusting components and snap-fit ​​components, achieves rapid assembly and meets the installation requirements under different road conditions, making it more practical.

[0006] To achieve the above objectives, this application provides the following technical solution: a municipal guardrail, comprising a guardrail body, an adjustment component, and a snap-fit ​​component. The adjustment component includes a bracket fixedly connected to one side of the guardrail body, an adjustment block rotatably connected to the inner wall of the bracket, a worm gear fixedly connected to the top of the adjustment block, and a worm engaging with the worm gear installed on one side of the guardrail body.

[0007] The snap-fit ​​assembly includes an H-shaped groove formed on the inner wall of the adjustment block. Two positioning rods are slidably fitted on the inner wall of the H-shaped groove. Fixing plates are fixedly connected to the outer surfaces of the two positioning rods. A telescopic spring is fitted on the outside of each fixing plate. An H-shaped block that matches the H-shaped groove is fixedly connected to the other side of the guardrail body. Two positioning holes are formed on the inner wall of the H-shaped block.

[0008] The above solution utilizes the meshing transmission between the worm gear and worm in the adjustment component to allow the adjusting block to rotate within a certain range. This enables stepless angle adjustment between the two guardrail bodies after assembly, effectively adapting to complex road conditions such as curves and intersections, making it more practical. The insertion and engagement of the H-shaped groove and H-shaped block in the snap-fit ​​component, combined with the positioning rod embedded in the positioning hole under the action of the telescopic spring, forms a mechanical lock, achieving rapid assembly and stable connection between the two guardrail bodies without the need for other tools, making it more convenient.

[0009] Furthermore, the guardrail body includes two posts and a fence assembly, the fence assembly being located between the two posts. The posts are made of high-strength aluminum alloy, and the fence assembly is made of carbon fiber composite material.

[0010] The above solution limits the materials used for the posts and fence components, ensuring the strength of the guardrail while reducing its weight.

[0011] Furthermore, the connection between the post and the fence assembly is provided with a flat connector and an L-shaped connector. The two posts and one fence assembly are connected by the flat connector and the L-shaped connector, both of which are made of stainless steel.

[0012] The above solution, through the use of planar connectors and L-shaped connectors, ensures the stability of the connection between the posts and the fence components, thus guaranteeing the protective effect of the guardrail body.

[0013] Furthermore, each of the columns is fixedly connected to a base at its bottom end, and each base has threaded holes at its four corners. The base is made of cast iron.

[0014] The above solution, with its base and threaded holes, allows the guardrail to be positioned more stably on the road surface.

[0015] Furthermore, a knob is fixedly connected to the shaft end of the worm gear, and the outer surface of the knob is provided with evenly distributed anti-slip textures.

[0016] The above solution allows for an increase in the contact area at the worm shaft end by using a knob, thus facilitating the rotation of the worm.

[0017] Furthermore, an extension piece is fixedly connected to the outer surface of each of the fixing pieces.

[0018] The above solution increases the contact area of ​​the outer surface of the fixing plate by adding an extension piece, making it easier to pull the positioning rod through the fixing plate.

[0019] Furthermore, the two ends of the telescopic spring are respectively fixedly connected to the outer surfaces of the corresponding fixing plate and adjusting block.

[0020] The above scheme defines the positional relationship of the telescopic springs. When the telescopic springs deform, they generate elastic force, which in turn allows the position of the positioning rod to be adjusted.

[0021] Furthermore, the inner diameter of the positioning hole is matched with the diameter of the positioning rod.

[0022] The above scheme defines the relationship between the positioning rod and the positioning hole, allowing the positioning rod to be inserted into the positioning hole to limit the H-block.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This type of municipal guardrail, through the meshing transmission of the worm gear and worm shaft in the adjusting component, and the rotation of the adjusting block driven by the knob, can achieve stepless angle adjustment between the two guardrail bodies after combination. It can effectively adapt to complex road conditions such as curves and intersections, making it more practical. The H-shaped groove and H-shaped block in the snap-fit ​​component are inserted and matched, and the positioning rod is embedded into the positioning hole under the action of the telescopic spring to form a mechanical lock, realizing the quick assembly and stable connection between the two guardrail bodies without the need for other tools, which is more convenient. The combination structure of high-strength aluminum alloy posts and carbon fiber fence components has a significant weight reduction compared to traditional steel guardrails. With the help of flat connectors and L-shaped connectors, a stable connection between the posts and fence components can be achieved, which can ensure impact resistance. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a municipal guardrail includes a guardrail body 1, an adjusting component 2, and a snap-fit ​​component 3. The guardrail body 1 includes two posts 101 and a fence component 102, with the fence component 102 located between the two posts 101. The posts 101 are made of high-strength aluminum alloy, and the fence component 102 is made of carbon fiber composite material. This material limitation of the posts 101 and fence component 102 ensures the strength of the guardrail body 1 while reducing its weight. A flat connector 103 and an L-shaped connector 104 are provided at the connection between the posts 101 and the fence component 102. The two posts 101 and the fence component 102 are connected by the flat connector 103. 3. The flat connector 103 and the L-shaped connector 104 are connected. Both the flat connector 103 and the L-shaped connector 104 are made of stainless steel. The flat connector 103 and the L-shaped connector 104 can ensure the stability of the connection between the post 101 and the fence assembly 102, and can reasonably disperse the stress generated by the impact, so as to ensure the protective effect of the guardrail body 1. Each post 101 is fixedly connected to a base 105 at the bottom. Each base 105 has threaded holes 106 at the four corners. The base 105 is made of cast iron. The base 105 and the threaded holes 106 can more stably position the guardrail body 1 on the road surface.

[0034] Please see Figure 2 , Figure 3 and Figure 4The adjusting component 2 includes a bracket 201 fixedly connected to one side of the guardrail body 1. An adjusting block 202 is rotatably connected to the inner wall of the bracket 201. A worm gear 203 is fixedly connected to the top of the adjusting block 202. A worm 204 meshing with the worm gear 203 is installed on one side of the guardrail body 1. A knob 205 is fixedly connected to the shaft end of the worm 204. The outer surface of the knob 205 is provided with evenly distributed anti-slip textures. By using the knob 205, the contact area of ​​the shaft end of the worm 204 can be increased, thereby facilitating the operation of rotating the worm 204. When rotating... Turning knob 205 will drive worm gear 204 to rotate. The rotation of worm gear 204 will drive worm wheel 203 to rotate. When worm wheel 203 rotates, the orientation of adjusting block 202 can be adjusted. The combination of worm wheel 203 and worm gear 204 has the effect of deceleration and self-locking, which can adjust adjusting block 202 to a suitable position and prevent adjusting block 202 from rotating randomly. This makes it easy to adjust the included angle between two adjacent guardrail bodies 1, thereby meeting the installation requirements under different road conditions.

[0035] Please see Figure 3 , Figure 4 and Figure 5 The snap-fit ​​assembly 3 includes an H-shaped groove 301 formed in the inner wall of the adjusting block 202. When the adjusting block 202 moves, the H-shaped groove 301 moves accordingly, facilitating subsequent adjustment of the angle between the two guardrail bodies 1. Two positioning rods 302 are slidably sleeved on the inner wall of the H-shaped groove 301. A fixing plate 303 is fixedly connected to the outer surface of each positioning rod 302. An extension plate 304 is fixedly connected to the outer surface of each fixing plate 303. The extension plate 304 increases the contact area of ​​the outer surface of the fixing plate 303, facilitating the pulling of the positioning rod 302 through the fixing plate 303. A telescopic spring 305 is sleeved on the outside of each fixing plate 303 for telescopic movement. The two ends of the spring 305 are fixedly connected to the outer surfaces of the corresponding fixing plate 303 and adjusting block 202, respectively, which limits the positional relationship of the telescopic spring 305. When the telescopic spring 305 deforms, it generates elastic force, which can adjust the position of the positioning rod 302. The other side of the guardrail body 1 is fixedly connected to an H-shaped block 306 that matches the H-shaped groove 301. The inner wall of the H-shaped block 306 has two positioning holes 307. The inner diameter of the positioning hole 307 matches the diameter of the positioning rod 302, which limits the relationship between the positioning rod 302 and the positioning hole 307, so that the positioning rod 302 can be inserted into the positioning rod 302 to limit the H-shaped block 306.

[0036] In this embodiment, a municipal guardrail, through the meshing transmission of the worm gear 203 and worm 204 of the adjusting component 2, and the rotation of the adjusting block 202 driven by the knob 205, can achieve stepless angle adjustment between the two guardrail bodies 1 after combination, effectively adapting to complex road conditions such as curves and intersections, making it more practical. The insertion and cooperation of the H-shaped groove 301 and H-shaped block 306 in the snap-fit ​​component 3, combined with the positioning rod 302 being embedded in the positioning hole 307 under the action of the telescopic spring 305, forms a mechanical lock, realizing the rapid assembly and stable connection between the two guardrail bodies 1 without the need for other tools, making it more convenient. The combination structure of high-strength aluminum alloy post 101 and carbon fiber fence component 102 has a significant weight reduction compared to traditional steel guardrails. With the help of the flat connector 103 and L-shaped connector 104, a stable connection between the post 101 and the fence component 102 can be achieved, ensuring impact resistance.

[0037] The working principle of the above embodiment is as follows: First, multiple guardrail bodies 1 can be quickly assembled using the snap-fit ​​assembly 3. The H-shaped block 306 on one side of the first guardrail body 1 is inserted into the H-shaped groove 301 of the adjacent guardrail. Simultaneously, the two corresponding positioning rods 302 need to be pulled outwards. The corresponding telescopic springs 305 will deform and generate elastic force. Then, the H-shaped block 306 is fully inserted into the H-shaped groove 301, and the pulled positioning rods 302 are released. At this time, the elastic force generated by the telescopic springs 305 can be used to reset the positioning rods 302, causing the two positioning rods 302 to be inserted into the two corresponding positioning holes 307 respectively, forming axial constraints. Finally, mechanical interlocking is achieved through the through-hole positioning rods 302, completing the two... During the assembly of the guardrail bodies 1, when it is necessary to adjust the installation angle of adjacent guardrail bodies 1, the operator rotates the knob 205 of the adjustment component 2. Through the reduction transmission of the worm gear 204 and worm wheel 203, the adjustment block 202 is driven to produce a precise angular deflection within the bracket 201. At this time, the self-locking characteristics of the worm gear 204 and worm wheel 203 can fix the adjustment angle in real time, avoiding displacement due to vibration. In the mechanical transmission path, the high-strength aluminum alloy base of the column 101 and the carbon fiber fence component 102 form a distributed load transmission network through the planar connector 103 and the L-shaped connector 104, so that the collision energy is dissipated in stages. The cast iron base 105 is anchored to the ground through the threaded hole 106 to form the final bearing support point, which is more practical.
