Description

Technical Field

[0001] This utility model relates to the field of road safety warning cone technology, and in particular to road traffic cones. Background Technology

[0002] Traffic cones, also known as cone-shaped road signs, cone tubes, red hats, or obelisks, are a type of road traffic isolation and warning facility. Three-dimensional traffic cones are cone-shaped road signs with a regular hexagonal cross-section, weighing up to 4500g. As indispensable temporary warning and isolation facilities in scenarios such as road construction and accident handling, the stability and applicability of traffic cones are directly related to road traffic safety.

[0003] With the acceleration of urbanization and the continuous expansion of highway mileage, traffic cones need to cope with severe conditions such as strong winds and complex road surfaces in different scenarios, including highways and suburban roads. As a key facility for temporary road warning and isolation, traffic cones play an important role in ensuring traffic safety during road construction and accident handling. However, traditional traffic cones mostly adopt a regular conical structure with a symmetrical conical surface on their outer perimeter. Although the overall shape is regular, the force is concentrated on the windward side. In windy road environments, wind resistance can easily cause traffic cones to tilt or shift, resulting in a deviation in the warning range, a sharp reduction in the warning effect, and in severe cases, even secondary traffic hazards.

[0004] Therefore, this utility model proposes a road traffic cone to solve the above problems. Utility Model Content

Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0028] Reference Figures 1-5 As shown, this embodiment provides a road traffic cone, including a traffic cone body 100, a support column 200, and a rotating base 300. The traffic cone body 100 is a flat frustum structure. The upper and lower ends of the support column 200 are respectively inserted into the traffic cone body 100 and the rotating base 300. The rotating base 300 includes a rotatable part, a fixed part, and a reset part. The lower end of the support column 200 is inserted into the center of the rotatable part of the rotating base 300. The rotatable part rotates relative to the fixed part around a vertical axis. The reset part is symmetrically installed on the fixed part and connected to the rotatable part so that after the rotatable part is rotated relative to the fixed part, it drives the rotatable part to reset, thereby enabling the traffic cone body 100 to adjust its angle according to the wind direction, reduce wind resistance, and maintain stability.

[0029] In one embodiment, the upper end of the traffic cone body 100 is a small end and the lower end is a large end. The outer peripheral surface of the traffic cone body 100 is a smoothly transitioning inclined surface, and the maximum radial dimension of the traffic cone body 100 is greater than the corresponding radial dimension of a traditional regular conical traffic cone, so as to form a larger windward bearing base. The longitudinal section of the traffic cone body 100 along its own axis is elliptical, the length of the major axis of the ellipse is greater than the length of the minor axis, and the elliptical dimension of the longitudinal section of the large end of the traffic cone body 100 is greater than the elliptical dimension of the longitudinal section of the small end. The length of the major axis of the elliptical section of the large end is greater than the maximum radial dimension of a traditional regular conical traffic cone. The difference between the radial major axis and the minor axis constitutes the flattened frustum structure of the traffic cone body 100.

[0030] In one embodiment, the rotatable part of the rotating base 300 includes an upper rotating insert ring 301, an upper bearing plate 304 mounted on the bottom surface of the upper rotating insert ring 301, and a plurality of rolling elements embedded in the bottom surface of the upper bearing plate 304. The fixed part includes a bearing bearing 302 tightly connected to the upper bearing plate 304 and an outer positioning ring plate 303 wrapped around the outer peripheral surface of the bearing bearing 302. The bottom surface of the outer positioning ring plate 303 is lower than the bottom surface height of the traffic cone body 100.

[0031] In one embodiment, the fixing part further includes a lower bearing plate 306 that is roll-mounted on the bottom surface of the rolling element. The lower bearing plate 306 is mounted on one end away from the rolling element. The lower bearing plate 306 is spaced apart from the bearing bearing 302. A suspension plate 307 is inserted into the lower bearing plate 306. The suspension plate 307 is spaced apart from the upper rotating insert ring 301.

[0032] Furthermore, the lower support plate 306 has a disc-shaped structure to increase the area of ​​the lower support plate 306 to achieve more contact with the ground, improve the friction between the fixed part of the rotating base 300 and the ground, and at the same time, the lower support plate 306 provides a stable mounting carrier for the suspended plate 307, adapting to suspended plates 307 of different weights to resist stronger wind resistance and meet the stability requirements in complex environments.

[0033] In one embodiment, the reset part of the rotating base 300 includes an outer extension plate 311 symmetrically mounted on the outer surface of the outer positioning ring plate 303. A column plate 312 is vertically inserted into the upper surface of the outer extension plate 311. Two inner base plates 315 are installed at positions corresponding to the column plates 312 on the upper rotating insert ring 301. Lifting rings 313 are installed on the opposite surfaces of the column plates 312 and the inner base plates 315. The two lifting rings 313 are hooked with hook springs 314.

[0034] Furthermore, the number of hook springs 314 is the same as the number of positioning inserts 203 and they are symmetrically distributed along the circumference of the upper rotating insert 301. The symmetrically arranged hook springs 314 provide a uniform reset force, so that the upper rotating insert 301 resets without resistance.

[0035] In one embodiment, the support column 200 includes a support column body 201 and a positioning plate 203 disposed at the lower end of the support column body 201. The positioning plate 203 extends outward along the radial direction of the support column body 201. There are multiple positioning plates 203, and the multiple positioning plates 203 are evenly spaced along the circumference of the support column body 201.

[0036] The inner sidewall of the upper rotating insert ring 301 is provided with slots 3011 that correspond one-to-one with the positioning inserts 203. The end of each positioning insert 203 away from the support column body 201 is inserted into a slot 3011 to realize the insertion and positioning of the support column 200 and the rotatable part. This insertion structure can limit the relative rotation between the support column 200 and the upper rotating insert ring 301, ensuring that the support column 200 drives the rotatable part to rotate synchronously around the vertical axis.

[0037] Furthermore, the bottom surface of the upper support plate 304 is provided with an annular groove, and the rolling element is a ball 305. Multiple balls 305 are evenly embedded in the annular groove along the circumference of the annular groove, and the lower end of the ball 305 protrudes out of the annular groove and rolls in contact with the upper surface of the lower support plate 306, so as to limit the ball 305 through the annular groove and ensure that the ball 305 rolls along a fixed trajectory.

[0038] Furthermore, the inner surface of the lower support plate 306 is provided with an insertion groove that is compatible with the suspension plate 307. The suspension plate 307 is inserted into the insertion groove in the vertical direction, and the height of the suspension plate 307 is higher than or equal to the height of the lower support plate 306. The suspension plate 307 can be detached and replaced through the insertion structure to adapt to different weight requirements in different application scenarios.

[0039] In one embodiment, the upper end of the support column body 201 is provided with a positioning hole 202, and the lower end face of the traffic cone body 100 is provided with a positioning post 101 adapted to the positioning hole 202. The positioning post 101 is inserted into the positioning hole 202 in a vertical direction to realize the detachable insertion and fitting of the traffic cone body 100 and the support column 200.

[0040] Furthermore, the lower surfaces of the lower support plate 306, the outer positioning ring plate 303, and the outer extension plate 311 are provided with anti-slip protrusions distributed circumferentially. The anti-slip protrusions are strip-shaped structures that extend radially along the lower support plate 306. The anti-slip protrusions can increase the friction coefficient between the lower support plate 306, the outer extension plate 311, and the ground, preventing the traffic cone from sliding laterally under strong winds. At the same time, the lower surfaces of the lower support plate 306, the outer positioning ring plate 303, and the outer extension plate 311 are simultaneously provided with anti-slip protrusions, which can make the contact friction force between the fixed part of the rotating base 300 and the ground evenly distributed, preventing the traffic cone from tilting or shifting due to local slippage, ensuring that the traffic cone is always in the preset road warning position, and ensuring that the warning effect does not fail.

[0041] Working principle: The traffic cone body 100 is designed as a flat frustum structure with an elliptical longitudinal section along its own axis. A reasonable windward bearing foundation is formed through radial dimension differences. Simultaneously, the maximum radial dimension is larger than that of a traditional regular conical traffic cone, and the minimum radial dimension is smaller than that of a traditional regular conical traffic cone, thus improving wind resistance dispersion. The upper end of the support column 200 is fixed to the positioning hole 202 of the traffic cone body 100 via a positioning column 101, and the lower end engages with the slot 3011 of the rotatable part of the rotating base 300 via a positioning insert plate 203, enabling synchronous rotation of both. The rotatable part consists of an upper rotating insert ring 301, an upper bearing plate 304, and ball bearings 305 embedded thereon. Through the rolling contact between the ball bearings 305 and the lower bearing plate 306 of the fixed part, the rotatable part can flexibly rotate around the vertical axis relative to the fixed part. The reset part of the rotating base 300 adopts... The symmetrical design features a vertically mounted column plate 312 on the outer extension plate 311 of the outer positioning ring plate 303. A hook spring 314 is hooked between the lifting ring 313 at the top of the column plate 312 and the inner base plate 315 corresponding to the lifting ring 313 of the upper rotating insert ring 301. When the wind pushes the traffic cone body 100 to rotate the rotatable part, the hook spring 314 deforms and stores energy. After the external force weakens, the rotatable part is precisely reset through the symmetrically distributed spring force. The lower bearing plate 306 of the fixed part is designed as a large-size disc structure to increase the contact area with the ground. The internally inserted suspension plate 307 can be weighted according to wind resistance requirements to lower the overall center of gravity. At the same time, the strip-shaped anti-slip protrusions on the lower surface of the lower bearing plate 306 and the outer extension plate 311 further increase the friction coefficient with the ground. The multiple structures work together to achieve wind direction adaptation, wind resistance reduction, and overall stability.

[0042] This application combines the traffic cone body 100 with an elliptical cross-section designed as a flattened frustum with a rotating base 300. This allows the traffic cone body 100 to automatically adjust its angle to adapt to the wind direction, converting the impact of strong winds on the body into rotational force. This effectively disperses the force on the windward side, solving the problem of traditional traffic cones being prone to tipping or displacement due to concentrated force on the windward side. The combination of the detachable suspension plate 307 and the large-size lower support plate 306 not only allows for flexible adjustment of counterweights to adapt to different wind resistance environments, but also lowers the center of gravity by increasing the ground contact area. Combined with the anti-slip effect of the anti-slip protrusions, this forms a triple stability guarantee of "lower center of gravity - increased area - enhanced friction," significantly improving the anti-tipping and anti-slip capabilities on complex road surfaces and in strong wind environments. The symmetrically distributed hook spring 314 reset assembly ensures uniform force on the rotatable part, high reset accuracy, and the ability to always maintain the preset warning direction, eliminating the need for frequent manual straightening and reducing operation and maintenance costs and safety risks.
