Description

Technical Field

[0001] The invention relates to the technical field of traffic sign installation, and in particular to a single-column sign board energy dissipation and anti-collision facility. Background Art

[0002] Single-column traffic signs generally adopt a fixed integrated design, including various shapes such as circles, triangles, regular octagons, etc., and are fixed by clamps. However, on curved roads, roads with limited vision or high speeds, collisions and scrapes between vehicles and the upper part of single-column signs frequently occur, resulting in vehicle damage, deformation of the sign structure, and even casualties.

[0003] The existing single-column sign needs to be replaced after deformation, resulting in high maintenance costs. In a scratch accident, the vehicle is subjected to a large force, causing serious damage to the vehicle and increasing the risk of casualties. Summary of the invention

[0004] According to the technical problems raised above, a single-column sign board energy dissipation and anti-collision facility is provided.

[0005] The technical means adopted by the present invention are as follows:

[0006] A single-column sign board energy dissipation and anti-collision facility includes a single-column sign board, wherein the single-column sign board includes a main board and side boards rotatably connected to both sides of the main board, the back side of the main board is installed and fixed to different positions of the column through multiple clamps, one of the clamps is connected to an energy dissipation device, and the other end of the energy dissipation device is connected to the side board.

[0007] Furthermore, the main body of the main board is the middle part of the traffic sign plate cut vertically into three parts, and longitudinal hollow main board connecting rods are arranged on both sides of the main board, and a longitudinal hollow side board connecting rod is arranged on the side where the side board body is connected to the main board. The main board connecting rod and the side board connecting rod have the same specifications, and the connection between the main board and the side board is completed by inserting connecting pins therein.

[0008] Furthermore, a transversely arranged connecting strip is provided on the back of the mainboard, and a clamp is provided on each connecting strip.

DETAILED DESCRIPTION

[0025] 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.

[0026] 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.

[0027] 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.

[0028] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the 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 part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] like Figures 1 to 8As shown, an embodiment of the present invention discloses a single-column sign board energy dissipation and anti-collision facility, including a single-column sign board, the single-column sign board 2 is installed above the column, the single-column sign board includes a main board 2.1 and side panels 2.2 rotatably connected to both sides of the main board, the back side of the main board is installed and fixed to different positions of the column 1 through multiple clamps 3, one of the clamps is used as an energy dissipation clamp 6 connected to an energy dissipation device, and the other end of the energy dissipation device is connected to the side panel.

[0033] Furthermore, the main body of the main board is the middle part of the traffic sign board cut vertically into three parts, and longitudinal hollow main board connecting rods 2.1.2 are arranged on both sides of the main board main body 2.1.1, and longitudinal hollow side board connecting rods 2.2.2 are arranged on the side where the side board main body 2.2.1 is connected to the main board, and the main board connecting rod and the side board connecting rod have the same specifications, and the main board and the side board are connected by connecting pins 2.3 inserted therein. At this time, the side board can rotate around the connecting rod.

[0034] Furthermore, a horizontally arranged connecting strip 4 is arranged on the back of the main board, and a clamp is arranged on each connecting strip. The clamp can be wrapped around the outside of the column, and screw holes are arranged at both ends of the clamp. The clamp is installed on the connecting strip by means of bolts 5 passing through the screw holes. The use of fastening screws and clamps ensures a firm connection between the sign board and the column. Even under a strong collision, the sign board will not easily fall off the column, thus maintaining the stability and visibility of the sign. The design of the entire structure is intended to minimize the negative impact of the collision while maintaining the functionality and aesthetics of the sign board.

[0035] As an optional embodiment, the energy dissipation device in Example 1 includes an energy dissipation structure support rod 6.2 connected to the clamp 6.1, and a spring structure is provided on the energy dissipation structure support rod. The other end of the spring structure is connected to the support rod connecting block 6.3, and the support rod connecting block 6.3 is connected to the side plate connecting block 2.2.3 installed on the side plate.

[0036] As another optional implementation, Figures 9-11 As shown, the energy dissipation device in Example 2 includes an energy dissipation spring 6.4 connected to the clamp, and the other end of the energy dissipation spring is connected to the side plate connecting block, and the side plate connecting block has a sliding groove structure so that the energy dissipation spring can slide therein.

[0037] The present invention replaces the traditional integrated sign board with a modular structure consisting of a main board and side boards. When a vehicle and the sign board are rubbed against each other, the design can absorb energy by means of the displacement change of the side boards, thereby effectively avoiding further deterioration of the accident and reducing the damage caused by the accident.

[0038] By setting up an energy dissipation structure, the structure can effectively resist the effects of natural wind and ensure the stability of the side panels under normal conditions. In extreme weather conditions, such as hurricanes, the support rod / shrapnel can unload the force through its own dynamic response mechanism, thereby significantly reducing the risk of the sign being blown off by strong winds.

[0039] Energy dissipation structure is set. In the event of a scratch accident, the support rod / shrapnel can effectively absorb the impact energy and reduce the damage caused by the collision. For minor damage, the signboard can be restored to its original state, thereby reducing the cost of repair and replacement after the accident.

[0040] Providing the sign board as a combination can improve the maintainability of the sign board. When individual components on the main board need to be replaced or repaired, they can be done separately without replacing the entire main board, thereby extending the service life of the entire sign board.

[0041] 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.
