Description

Technical Field

[0001] This utility model relates to the field of road sign technology, and in particular to a flip-out delineator for highways. Background Technology

[0002] Highways are the lifeline and main artery of a region's development, and ensuring their smooth flow is crucial for promoting regional development and safeguarding regional security. Traffic safety facilities are extremely important on highways and are a key component of maintenance and construction operations. However, highway maintenance work is inherently dangerous, and ensuring the lifespan of highway signs while simultaneously saving costs remains a persistent challenge.

[0003] Reflective delineators play a particularly important guiding role on highways. Due to the high speed of vehicles and complex traffic conditions on highways, especially in tunnel environments and at night, traffic accidents may occur where vehicles collide with guardrails or tunnel walls. In such cases, the delineators installed on the guardrails or tunnel walls may be damaged.

[0004] Existing delineators, such as the one mentioned in Chinese Utility Model Patent No. 201720733118.4, include a trapezoidal frame and a square reflector. The square reflector is symmetrically distributed on the inclined surface of the trapezoidal frame, and through holes A and B are opened on the bottom and top surfaces of the trapezoidal frame. The square reflector includes a base plate, a reflective film, and a reflective protective layer. While it provides a good warning effect and protects the lives of passengers, it does not consider the protection and wear and tear of the delineator. Once the reflector fails, the entire delineator needs to be replaced. Replacing the entire delineator not only consumes more materials but also requires repositioning the new delineator, a time-consuming and labor-intensive operation that is unsuitable for the rapid maintenance requirements of highways. Utility Model Content

[0005] The technical problem this invention aims to solve is how to quickly and accurately repair delineator structures to rapidly restore the highway traffic environment.

[0006] To achieve the above objectives, according to one aspect of the utility model, a highway insert-type delineator is provided, comprising a base and a reflective unit. The base includes a protrusion and inclined portions disposed opposite to each other on both sides of the protrusion. The reflective unit is disposed on the inclined portions, and a limiting structure for inserting and defining the position of the reflective unit is provided on the inclined portions. The reflective unit is detachably connected to the base through the limiting structure.

[0007] As a preferred embodiment of the above technical solution, a transparent protective layer is further provided on the base, the transparent protective layer covers the outside of the reflective unit, and a collision buffer is provided between the transparent protective layer and the reflective unit.

[0008] As a preferred embodiment of the above technical solution, the transparent protective layer includes an arc-shaped surface, and the arc-shaped surface is tangent to the end face of the protrusion; the end face of the protrusion is parallel to the bottom surface of the base.

[0009] As a preferred embodiment of the above technical solution, the inclined portion includes a plurality of reinforcing ribs, the reinforcing ribs being located within the coverage area formed by the transparent protective layer and the base, and the reinforcing ribs including at least one inclined assisting surface that contacts and supports the inclined arrangement of the reflective unit.

[0010] As a preferred embodiment of the above technical solution, the transparent protective layer is provided with a matching buckle, and the reinforcing rib is provided with a matching recess that matches the matching buckle.

[0011] As a preferred embodiment of the above technical solution, a connecting portion is provided on the side of the inclined portion away from the protrusion. The connecting portion, the protrusion, and the inclined portion are integrally formed. The connecting portion is fixedly connected to the environmental substrate by fasteners. A countersunk structure is provided on the connecting portion, and the fasteners are embedded in the connecting portion through the countersunk structure.

[0012] The so-called environmental matrix refers to the structures commonly found on highways, such as guardrails and tunnel walls.

[0013] As a preferred embodiment of the above technical solution, the inclined portion further includes a slope surface, the reinforcing rib is disposed on the slope surface, and the inclination angle of the inclined assisting surface is greater than the inclination angle of the slope surface.

[0014] As a preferred embodiment of the above technical solution, the limiting structure includes a longitudinal limiting part and a transverse limiting part. The transverse limiting part is disposed on the left and right sides of the reflective unit to limit the reflective unit laterally, and the longitudinal limiting part is disposed on the lower side of the reflective unit to limit the reflective unit longitudinally. The upper end of the limiting structure has an opening for the reflective unit to enter.

[0015] As a preferred embodiment of the above technical solution, the reflective unit includes a reflective film and a tough plastic outer shell structure that surrounds the reflective film.

[0016] As a preferred embodiment of the above technical solution, the base is a corrosion-resistant structure formed by a combination of fiber composite materials and engineering plastics.

[0017] In summary, this utility model has the following advantages:

[0018] 1. The reflective unit on the delineator of this utility model is a replaceable structure. When the reflective unit loses its function after being exposed to sun and rain for a long time, the maintenance personnel only need to replace the reflective unit. When assembling the new reflective unit, due to the positioning of the limit structure, the assembled reflective unit can be put into use immediately without further calibration, which is efficient and saves materials.

[0019] 2. Furthermore, the transparent protective layer is used to further protect the reflective unit, while the collision buffer zone located between the transparent protective layer and the reflective unit provides deformation space for the transparent protective layer, effectively blocking damage to the reflective unit from frontal impacts;

[0020] 3. Furthermore, the reinforcing ribs set on the base further enhance the support strength of the reflective unit. At the same time, the reinforcing ribs can help support and adjust the reflective unit to be set at a larger tilt angle, so as to improve the reflective effect of the reflective unit.

[0021] Further or other beneficial effects will be discussed in the embodiments. Attached Figure Description

Detailed Implementation

[0029] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0030] The present invention will be further explained below with reference to the embodiments:

[0031] Example:

[0032] A type of delineator for highways, reference Figure 1 and Figure 2 The device includes a base 1 and a reflective unit 2. The base 1 includes a protrusion 11 and an inclined portion 12 disposed on both sides of the protrusion 11. The reflective unit 2 is disposed on the inclined portion 12. The inclined portion 12 is provided with a limiting structure 3 for inserting and limiting the position of the reflective unit 2. The reflective unit 2 is detachably connected to the base 1 through the limiting structure 3.

[0033] The limiting structure 3 is used to limit and fix the reflective unit 2. The reflective unit 2 includes a reflective film and a plastic shell structure wrapped around the reflective film. The plastic shell has good toughness and can be bent and deformed to a certain extent. The plastic shell structure is equivalent to the exoskeleton of the reflective film, protecting the reflective film and ensuring that the reflective unit 2 is a sheet-like structure so that the reflective unit 2 has a certain deformation ability without affecting the reflective function of the reflective film. The base 1 is a corrosion-resistant structure formed by combining fiber composite materials and engineering plastics.

[0034] Reference Figure 3 , Figure 4 and Figure 5 The specific limiting structure 3 includes a longitudinal limiting part 31 and a transverse limiting part 31. The transverse limiting part 31 is disposed on the left and right sides of the reflective unit 2 to limit the reflective unit 2 laterally, and the longitudinal limiting part 31 is disposed on the lower side of the reflective unit 2 to limit the reflective unit 2 longitudinally. The upper end of the limiting structure 3 has an opening 33 for the reflective unit 2 to enter.

[0035] In other words, in this embodiment, the limiting structure 3 can restrict the position of the reflective unit 2. When the reflective unit 2 loses its function due to prolonged exposure to sun and rain, it can be quickly maintained by replacing the reflective unit 2. The new reflective unit 2 enters the limiting structure 3 through the opening 33, moves downward under the action of gravity, and is finally supported longitudinally by the longitudinal limiting part 31. Its left and right sides are limited by the transverse limiting part 31. This method allows for fast replacement and low material consumption.

[0036] As a further optimization, since this invention is a product installed on highway guardrails or tunnel walls, there is a possibility of vehicles hitting the delineator. To protect the reflective unit 2, this invention provides a transparent protective layer 4 on the base 1. The transparent protective layer 4 covers the outside of the reflective unit 2, and a collision buffer zone is set between the transparent protective layer 4 and the reflective unit 2. The transparent protective layer 4 is made of highly transparent plexiglass (such as acrylic sheet), allowing light to reach the reflective unit 2 and be reflected. The transparent protective layer 4 has a tough structure and a certain degree of deformation capability. The aforementioned collision buffer zone refers to the deformable space of the transparent protective layer 4 towards the reflective unit 2. Thus, in the event of a vehicle hitting the delineator, the transparent protective layer 4 not only protects the reflective unit 2, but also deforms inward to dissipate force, thereby protecting itself from damage and extending the service life of the entire structure.

[0037] In this embodiment, the end face of the protrusion 11 is parallel to the bottom surface of the base 1. The transparent protective layer 4 includes an arc-shaped surface 41, which is tangent to the end face of the protrusion 11. When the vehicle scrapes against the delineator, the impact can naturally transition to the end face of the protrusion 11 through the guidance of the arc-shaped surface 41, effectively buffering the impact. Unlike sharp corners, the arc-shaped surface 41 can protect the vehicle's paint, thereby reducing economic losses.

[0038] The inclined portion 12 includes a ramp surface 121 and several reinforcing ribs 5. The reinforcing ribs 5 are located inside the coverage area formed by the transparent protective layer 4 and the base 1. The reinforcing ribs 5 include an inclined assisting surface 51 that contacts and supports the inclined arrangement of the reflective unit 2. The limiting structure 3 mentioned above is disposed on the reinforcing ribs 5. The arrangement of the reinforcing ribs 5 provides effective support for the transparent protective layer 4, while the inclined assisting surface 51 on the reinforcing ribs 5 can assist the reflective unit 2 to tilt at a larger tilt angle, thereby achieving a more effective reflection effect. In addition, the two ramp surfaces 121 and the protrusion 11 form a trapezoidal structure, more precisely, an isosceles trapezoidal structure. This structure is the basic framework of this utility model, and the other structures are extensions thereof. The reinforcing ribs 5 are set on the ramp surface 121. The tilt angle of the inclined assisting surface 51 is greater than that of the ramp surface 121. A portion of the space is formed between the ramp surface 121, the reinforcing ribs 5, and the reflective unit 2. This reduces the material consumption for manufacturing the base 1 while ensuring support for the reflective unit 2. Thus, because the tilt angle of the inclined assisting surface 51 is greater than that of the ramp surface 121, the tilt angle of the reflective unit 2 supported by the inclined assisting surface 51 is larger. The width of the entire delineator is relatively larger, but the thickness is smaller. Compared with the more prominent traditional delineator structure, its reflective effect is similar. However, because it is not prominent, it is not easily bumped by passing vehicles, thus improving its service life.

[0039] A connecting part 13 is provided on the side of the inclined part 12 away from the protrusion 11. The connecting part 13, the protrusion 11 and the inclined part 12 are integrally formed. The connecting part 13 is fixedly connected to the environmental substrate (such as guardrail, tunnel wall, etc.) by fasteners 6. A countersunk structure 131 is provided on the connecting part 13. The fasteners 6 are embedded in the connecting part 13 through the countersunk structure 131. The above is the connection method between the entire delineator and the environmental substrate. The fasteners 6 are bolts. By using the countersunk method, the fasteners 6 do not interfere with other structures of the delineator.

[0040] Please refer to Figure 6 The transparent protective layer 4 is provided with a matching buckle 42, and the reinforcing rib 5 is provided with a matching recess 52 that matches the matching buckle 42. The matching buckle 42 forms a fit by inserting into the matching recess 52. Specifically, the matching buckle 42 is provided with a deformation area, so that the matching buckle 42 can deform laterally when inserted longitudinally. After reaching the final position, the elastic potential energy is released, the structure of the matching buckle 42 is restored, and it is longitudinally locked with the matching recess 52 to complete the fit. In addition, a matching recess 52 can also be provided on the connecting part 13 mentioned above, and a matching buckle 42 can be added at the corresponding position of the transparent protective layer 4, thereby further strengthening the fit between the transparent protective layer 4 and the base 1.
