Description

Technical Field

[0001] This utility model relates to the field of traffic safety facilities technology, specifically to an elastic warning post. Background Technology

[0002] Warning posts are a common road traffic safety facility, mainly used to separate lanes, warn of dangerous areas, or guide vehicle travel. They are widely used in road boundaries, parking lots, construction areas, and dangerous road sections. Traditional warning posts are usually made of metal, such as steel or aluminum alloy, with yellow and black warning lines formed on their surface by spraying paint or pasting reflective stickers to achieve a visual warning function.

[0003] However, traditional metal warning posts have some problems in practical applications. On the one hand, traditional warning posts are too hard and cannot effectively buffer the impact force when a vehicle collides, which may cause scratches on the vehicle paint or even structural damage, increasing accident losses. On the other hand, the warning lines on the surface of traditional warning posts rely on the integrity of the external coating or sticker. Under conditions such as vehicle scratches or long-term exposure to wind and sun, the paint coating and stickers are prone to peeling off and fading, causing the warning lines to become blurred or even disappear, significantly reducing the warning effect.

[0004] Therefore, how to provide an elastic warning post that overcomes the shortcomings of existing technologies is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] Therefore, this utility model provides an elastic warning post to solve the problems in the prior art where the high hardness of traditional warning posts makes them unable to effectively buffer the impact force during vehicle collisions, and where the warning lines on the surface of traditional warning posts rely on external coatings or stickers, which are prone to peeling and fading, resulting in scratches on the vehicle paint or even structural damage and reduced warning effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model discloses an elastic warning post, comprising:

[0008] The inner cylinder is a hollow cylindrical structure with openings at both ends;

[0009] The outer cylinder is disposed on the outer side wall of the inner cylinder and is bonded to the inner cylinder to form an integrated structure;

[0010] The outer cylinder includes at least a set of alternating first and second color blocks, and the outer cylinder is formed by the first and second color blocks spiraling along a virtual spiral line.

[0011] Furthermore, there are two sets of the first color block and the second color block, and the outer wall of the outer cylinder is formed with spiral stripes. The spiral stripes are arranged from top to bottom as first color block stripe one, second color block stripe one, first color block stripe two, and second color block stripe two.

[0012] Furthermore, both the inner cylinder and the outer cylinder are made of rubber.

[0013] Furthermore, the pitch of the spiral stripes is 10-30 cm.

[0014] Furthermore, the first color block is black, and the second color block is yellow.

[0015] Furthermore, it also includes a load wheel, a base, and a top cover. The load wheel is installed on the top of the base, the inner cylinder is installed on the top of the base and nests the load wheel inside, and the top cover is inserted into the upper end of the inner cylinder.

[0016] A resilient guardrail includes the resilient warning posts, the number of which is at least three. The resilient warning posts are vertically installed on the ground, and a resilient warning post is inserted horizontally between two adjacent resilient warning posts.

[0017] This utility model has the following advantages:

[0018] This invention features an inner and outer cylinder. The outer cylinder is formed by extruding black and yellow rubber granules through a dual-channel co-extruder and then rotating it through a traction machine to create a hollow cylindrical structure with spiral stripes. This results in permanent alternating yellow and black spiral stripes, ensuring that even with surface wear or impacts, the interior retains its original color, unlike traditional paint or stickers that fade with wear. This completely solves the problem of reduced warning effectiveness caused by coating peeling from traditional metal warning posts, significantly extending the product's lifespan. The spiral stripe design provides dynamic visual cues during vehicle movement, enhancing driver alertness and making it more easily recognizable than traditional straight-strip warning posts.

[0019] Meanwhile, the inner and outer cylinders, made of rubber, not only utilize the high elasticity and deformation properties of rubber to absorb kinetic energy during vehicle collisions, reducing the impact on the vehicle body and avoiding the scratches or dents that are easily caused by traditional metal warning posts, thus significantly improving road traffic safety, but also eliminate the risk of corrosion. This allows for use in harsh environments such as humid and saline-alkali areas without the need for regular anti-corrosion maintenance, expanding its applicability and enhancing its practicality. Furthermore, the internal load-bearing wheels further enhance the wind resistance stability and impact-resistant self-resetting capability of the elastic warning post. Attached Figure Description

Detailed Implementation

[0030] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. 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.

[0031] Please refer to Figures 1-7 The elastic warning post disclosed in this utility model will now be described, such as... Figure 1 , Figure 2 , Figure 3 As shown, this utility model discloses an elastic warning post, including an inner cylinder 1 and an outer cylinder 2. The inner cylinder 1 is a hollow cylindrical structure with openings at both ends. The outer cylinder 2 is disposed on the outer side wall of the inner cylinder 1 and is integrally bonded to the inner cylinder 1 through vulcanization. The outer cylinder 2 includes at least a set of alternating first color blocks 21 and second color blocks 22, which are spirally formed along a virtual spiral line. Preferably, both the inner cylinder 1 and the outer cylinder 2 are made of rubber. In this embodiment, the inner cylinder 1 and the outer cylinder 2 are made of rubber. The outer cylinder 2 is formed by extruding two different colors of the same type of rubber through a dual-channel co-extruder and then rotating and pulling it through a traction machine to form a hollow cylindrical structure with spiral stripes. Compared with traditional metal materials, this fundamentally eliminates the risk of metal corrosion, allowing it to be used in harsh environments such as humid and saline-alkali conditions without the need for regular anti-corrosion maintenance, thus expanding its applicability and enhancing its practicality. The positional relationship between the inner cylinder 1 and the outer cylinder 2 is as follows: Figure 2 As shown, the inner cylinder 1 and outer cylinder 2 are an integrated two-layer structure. The inner cylinder 1 is extremely thin, while the outer cylinder 2 is thicker. The inner cylinder 1 and outer cylinder 2 can be bonded together using methods such as vulcanization bonding, bonding with special rubber adhesives (such as neoprene rubber, polyurethane adhesive, epoxy resin adhesive, etc.), or hot-melt bonding (softening them by heating and pressing them with other materials, then cooling to form a single unit). After processing, the inner cylinder 1 and outer cylinder 2 can be integrated at the molecular level, with no gaps at the joint, enhancing structural strength and durability. Simultaneously, the rubber material of the inner cylinder 1 and outer cylinder 2 utilizes the high elastic deformation properties of rubber to absorb kinetic energy through deformation during vehicle collisions, reducing the impact on the vehicle body and avoiding the scratches or dents that are easily caused by traditional metal warning posts, significantly improving road traffic safety.

[0032] like Figure 2 , Figure 3As shown, there are two sets of first color blocks 21 and second color blocks 22. The outer wall of the outer cylinder 2 is formed with spiral stripes 23, which are arranged from top to bottom as follows: first color block stripe 211, second color block stripe 221, first color block stripe 212, and second color block stripe 222. Preferably, the pitch of the spiral stripes 23 is 10-30 cm. In this embodiment, the distribution and shape of the first color blocks 21 and second color blocks 22 are as follows... Figure 2 As shown, the outer cylinder 2 has a circular cross-section, with two first color blocks 21 and two second color blocks 22 each occupying 1 / 4 of the circumference. The spiral stripes 23 are formed by the two first color blocks 21 and two second color blocks 22 spiraling along a virtual spiral line. The alternating first color blocks 21 and two second color blocks 22, after spiraling, form four alternating colored stripes. The outer cylinder 2 is integrally molded from black and yellow rubber granules through extrusion and spiral traction processes, forming permanent yellow and black alternating spiral stripes. Even if the surface is worn or bumped, the interior retains its original color and will not fade due to wear like traditional paint or stickers. This completely solves the problem of reduced warning effect caused by the peeling of the surface coating of traditional metal warning posts, significantly extending the product's lifespan. The spiral stripes 23 are designed to create dynamic visual cues during vehicle movement, enhancing driver alertness and providing better visibility than traditional straight-strip warning posts. The pitch of the spiral stripes 23 can be adjusted according to actual conditions, ranging from 10-30cm. Different pitches create different dynamic visual cues at different vehicle speeds.

[0033] like Figure 2 As shown, the first color block 21 is black, and the second color block 22 is yellow. In this embodiment, both the inner cylinder 1 and the first color block 21 are made of black rubber, therefore... Figure 2 The inner cylinder 1 has no clear boundary with the first color block 21, but it has a clear boundary with the second color block 22. The black and yellow warning color blocks conform to internationally accepted safety color standards, ensuring a high-contrast warning effect; red and white, or other high-contrast color blocks that conform to internationally accepted safety color standards, can also be selected. The outer cylinder 2 is made of rubber granules with its own color, avoiding the environmental pollution caused by metal spraying processes, and conforming to the development trend of green transportation facilities.

[0034] like Figure 1 , Figure 4 , Figure 5As shown, the device also includes a load wheel 3, a base 4, and a top cover 5. The load wheel 3 is mounted on the top of the base 4, and an inner cylinder 1 is mounted on top of the base 4, nesting the load wheel 3 inside. The top cover 5 is inserted into the upper end of the inner cylinder 1. In this embodiment, the load wheel 3 is a honeycomb-type high-elasticity structure load wheel 3. The base 4 is fixed to the ground by bolts at the four corners. The inner cylinder 1 is nested outside the load wheel 3, and an integrated outer cylinder 2 is located outside the inner cylinder 1. The load wheel 3 is a commonly used device in the prior art, and its core components typically include a wheel body, a counterweight, and a rotating mechanism. By setting the load wheel 3, the device's wind resistance and impact self-resetting ability are enhanced.

[0035] like Figure 6 , Figure 7 As shown, a resilient guardrail includes resilient warning posts, with at least three resilient warning posts. The resilient warning posts are vertically installed on the ground, and a third resilient warning post is inserted horizontally between two adjacent posts. In this embodiment, the resilient guardrail has various forms, such as... Figure 6 Multiple vertical and horizontal flexible warning posts can be used to enclose the area requiring protection; for example... Figure 7 It can also be horizontally plugged in to form an scalable protection network, adapting to complex scenarios such as road curves and toll stations, and improving the flexibility and stability of large-scale applications.

[0036] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
