Description

Technical Field

[0001] The present invention relates to the technical field of traffic sign installation, and in particular to a central dividing guardrail end rebound warning device. Background Art

[0002] Urban road central divider guardrails are important facilities used to separate opposing traffic flows and ensure driving safety. They are usually made of metal materials and have certain strength and durability. Existing central divider guardrails are mostly linear in design, which can effectively guide the direction of vehicle travel and reduce the occurrence of traffic accidents.

[0003] However, due to the complex and changeable urban road environment, the existing guardrails have certain safety hazards in the end treatment. If the end is not properly handled, vehicles will collide during driving, which can easily cause the guardrail end to deform or be damaged, and even cause more serious traffic accidents. Therefore, the design improvement of the end of the central dividing guardrail is an urgent problem to be solved in the current traffic safety field.

[0004] At present, the ends of the central dividing guardrails of urban roads are generally not specially treated, or warning reflective strips are pasted to warn drivers. Once a vehicle enters the lane, especially when turning left or right, it is easy for the vehicle to scrape against the end of the guardrail, causing the guardrail to deform, the vehicle to be damaged, and traffic jams.

[0005] Once the end of the guardrail is scratched by a vehicle, the entire guardrail needs to be replaced. The end of the guardrail cannot be partially replaced, resulting in increased subsequent maintenance costs. Summary of the invention

[0006] In response to the technical problem raised above, a central dividing guardrail end rebound warning device is provided.

[0007] The technical means adopted by the present invention are as follows:

[0008] A rebound warning device for the end of a central dividing guardrail comprises a column clamp, a rebound warning plate, a support rod and a hinged column. The column clamp can be sleeved on the support column of the guardrail. The hinged column is arranged parallel to the support column of the guardrail. A plurality of support rods are arranged between the hinged column and the column clamp. Rebound warning plates that can rotate along the hinged column are respectively installed along both ends of the hinged column.

[0009] Furthermore, the rebound warning plate is an arc-shaped plate, the inner side of which is connected to the outer wall of the column clamp through a spring.

[0010] Furthermore, the column clamp is an annular clamp with a notch, one end of which is rotatably connected to a column clamp fastening plate. After the column clamp fastening plate is installed, the column clamp fastening plate and the annular clamp are locked by bolts.

[0011] Furthermore, a warning reflective strip is provided on the outer wall surface of the rebound warning plate.

[0012] Furthermore, the number of the support rods is at least 2, and the number of the springs connected to each rebound warning plate is at least 2.

[0013] Compared with the prior art, the present invention has the following advantages: Under normal conditions, the rebound warning plate is affixed with a warning reflective strip to warn passing vehicles. When the vehicle slightly scrapes against the end rebound warning device, the rebound warning plate can restore to its original state under the action of the spring. When the vehicle collides with the end rebound warning device, causing significant damage and deformation, the warning device can be used to protect the column, and the column can continue to be protected after the warning device is replaced, reducing the replacement cost of replacing all central dividing guardrails. The design of the end rebound warning device can well adapt to the current use requirements of urban road dividing guardrails, cope with vehicle collisions of varying degrees, and subsequent maintenance is quick and convenient.

DETAILED DESCRIPTION

[0023] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0026] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0027] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0028] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0029] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0030] like Figures 1 to 6 As shown, an embodiment of the present invention discloses a rebound warning device 2 for the end of a central dividing guardrail, comprising a column clamp 2.1, a rebound warning plate 2.5, a support rod 2.3 and a hinged column 2.4, wherein the column clamp 2.1 can be sleeved on the support column 1.1 of the guardrail 1. In this embodiment, the guardrail 1 comprises an intermediate protective body and support columns 1.1 arranged at both ends, a column cap 1.2 is arranged above the support column, and a base 1.3 is arranged below, a main cross beam 1.4 is arranged above the intermediate protective body, the hinged column 2.4 is arranged parallel to the support column 1.1 of the guardrail 1, a plurality of support rods 2.3 are arranged between the hinged column 2.4 and the column clamp 2.1, and rebound warning plates 2.5 that can rotate along the hinged column 2.4 are respectively installed along both ends of the hinged column 2.4.

[0031] Furthermore, the rebound warning plate 2.5 is an arc-shaped plate, the inner side of which is connected to the outer wall of the column clamp 2.1 through a spring 2.6. As a preferred embodiment, the hinge column is arranged at the midpoint of the arc-shaped plate.

[0032] Furthermore, the column clamp is an annular clamp with a notch, one end of which is rotatably connected to a column clamp fastening piece 2.2. After the column clamp fastening piece is installed, the column clamp fastening piece and the annular clamp are locked by bolts 2.7.

[0033] Furthermore, a warning reflective strip is provided on the outer wall surface of the rebound warning plate.

[0034] Furthermore, the number of the support rods is at least 2, and the number of the springs connected to each rebound warning plate is at least 2.

[0035] In actual use, the support rod can be in the same plane as the main cross beam 1.4, such as Figure 4 As shown, or the two are not in the same plane, such as Figure 5 As shown, it is suitable for different road environments and can be adjusted according to specific application scenarios.

[0036] The working principle of the present invention is as follows: (1) Under normal conditions, a warning reflective strip (red and white) is attached to the rebound warning plate to warn passing vehicles.

[0037] (2) When the vehicle slightly scrapes against the end rebound warning device, the vehicle collides with the rebound warning plate, squeezing the spring bar (under pressure), causing the position to change, such as Figure 6 As shown, the driver senses a scratch, stops the car, adjusts the position, and continues driving. At this time, the spring bar is not pressed by external force, and returns to its original state, allowing it to reset. If a slight scratch occurs between the vehicle and the end of the guardrail, the vehicle can reset itself through its own deformation, thus reducing traffic congestion.

[0038] (3) When a vehicle collides with the end rebound warning device, causing significant damage and deformation, the rebound warning device 2 can effectively protect the guardrail 1. After the accident, the guardrail 1 can be used normally by replacing the rebound warning device 2. There is no need to replace the entire guardrail, which is fast and effective, and at the same time, reduces the cost of later maintenance.

[0039] Compared with traditional signs, this design has a more novel structure and no longer a single function. It effectively optimizes the combination of existing crash barrels and guardrails. At the same time, the warning effect is more intuitive.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
