Technical Field
[0001] This utility model relates to the field of road barriers, and in particular to a self-resetting, non-tipping road barrier. Background Technology
[0002] Roadblocks are facilities used for road traffic safety. They are typically made of plastic or rubber cones, brightly colored for high visibility. Roadblocks are used to mark road construction areas, indicate traffic flow, warn of dangerous areas, or restrict vehicle movement. For example, during road construction or maintenance, roadblocks are placed around the construction area to guide vehicles and pedestrians around the work area. Additionally, roadblocks are used to mark parking lots, indicate parking spaces, or guide traffic at accident scenes.
[0003] Typically, roadblocks consist of cones and a base. The base increases the footprint, improving grip on the ground; the cones are usually used to add markings for visibility and warning, and to facilitate stacking. Because roadblocks are often used in complex outdoor environments, such as roads, they are easily affected by strong winds or passing vehicles. Therefore, we often see fallen roadblocks in our daily lives. These not only fail to achieve their intended warning effect, but the movement of fallen roadblocks can even create traffic safety hazards.
[0004] To address these issues, some existing technologies utilize counterweights, such as casting concrete inside the cone, to increase the weight of the roadblock and improve stability. However, this increased weight not only leads to higher costs but also hinders transportation and use. Other existing technologies reference the principle of a roly-poly toy, proposing novel roly-poly-style roadblocks. While these achieve a degree of stability, their curved base presents two problems: first, their grip is weak, and even slight wind can cause them to sway and shift from their intended position; second, their curved base restricts stacking, hindering storage and transportation, and making them inconvenient to use. Utility Model Content
[0005] The purpose of this invention is to provide a self-resetting, non-tipping road barrier to solve the problems mentioned in the background art.
[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0007] A self-resetting, non-tipping traffic cone includes a cone cap and an annular base.
[0008] The maximum outer diameter of the cone-shaped structure at the top of the cone cap is R1, and the height of the cone cap is H;
[0009] The annular base includes an upper connecting part and a lower counterweight part. The maximum outer diameter R2 of the counterweight part is greater than the maximum outer diameter of the connecting part. Both the connecting part and the counterweight part are hollow structures, and counterweight cavities are provided inside the counterweight part and the connecting part.
[0010] The counterweight cavity contains a counterweight and satisfies the following conditions: Where W1 is the total weight of the counterweights and W2 is the weight of the cone cap;
[0011] The traffic cone is designed such that when it falls to the ground under external force, the outer edge of the counterweight and the outer edge of the cone-shaped structure at the top of the cone cap are the only contact points with the ground plane. The dimensional ratio between R1, R2 and H satisfies the following: when the traffic cone falls to the ground, the angle α between the normal line A passing through the contact point of R1 and the ground and perpendicular to the ground plane and the axis line O passing through the center of R1 and R2 is less than 90°, and the center of gravity of the counterweight deviates from the contact point. Under the action of the weight of the counterweight, the traffic cone is forced to return to the upright position.
[0012] As a preferred technical solution of this application, the maximum outer diameter R2 of the counterweight part of the annular base is a fixed value, and R1 is adapted to the center of gravity requirements of the conical cap with different heights H.
[0013] As a preferred technical solution of this application, the bottom of the cone cap is provided with a downwardly extending connecting section, and the middle of the connecting part located on the upper part of the annular base is provided with a hollow insertion interface adapted to the connecting section. The outer diameter of the connecting section is slightly smaller than the inner diameter of the hollow insertion interface, so that the cone cap can be detachably inserted into the annular base.
[0014] As a preferred technical solution of this application, the cone cap and the connecting part are such that the counterweight part is fixedly connected to the bottom of the connecting part.
[0015] As a preferred technical solution of this application, the height of the cone cap is 500mm, and the dimensions of its maximum outer diameter R1 at the top, the maximum outer diameter R2 of the counterweight, and the total weight W1 of the counterweight are adapted to the center of gravity requirements of this height, satisfying the self-resetting condition that the included angle α < 90° after falling to the ground.
[0016] As a preferred technical solution of this application, the height of the cone cap is 700mm, and the dimensions of its maximum outer diameter R1 at the top, the maximum outer diameter R2 of the counterweight, and the total weight W1 of the counterweight are adapted to the center of gravity requirements of this height, satisfying the self-resetting condition that the included angle α < 90° after falling to the ground.
[0017] As a preferred technical solution of this application, the height of the cone cap is 900mm, and the dimensions of its maximum outer diameter R1 at the top, the maximum outer diameter R2 of the counterweight, and the total weight W1 of the counterweight are adapted to the center of gravity requirements of this height, satisfying the self-resetting condition that the included angle α < 90° after falling to the ground.
[0018] As a preferred technical solution of this application, the cone cap is hollow inside, and the counterweight part and the connecting part of the annular base together form an annular structure, so that multiple traffic cones of the same specification can be nested and stacked with each other.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] In the scheme of this application:
[0021] 1. By unifying the outer diameter of the counterweight part of the ring base to a fixed size, the bases of three different height traffic cones are made completely universal. This design completely eliminates the need for developing molds for multiple specifications of bases, greatly reducing the investment in production equipment. At the same time, it simplifies the assembly process, reduces the types of parts in stock, and improves the compatibility of the production line. The universal base forms an intensive advantage in large-scale manufacturing, which significantly reduces the unit product cost and is especially beneficial to the market promotion of serialized products.
[0022] 2. For traffic cones of three heights (500mm, 700mm, and 900mm), a dynamic adjustment strategy combining a gradient design of the cone top diameter and a differentiated counterweight ratio is adopted. Under the constraint of a fixed base size, the center of gravity is lowered by reducing the top diameter of the low-profile cone, and the stability is enhanced by increasing the top diameter of the high-profile cone. The mass ratio of the counterweight is also adjusted in a coordinated manner, so that traffic cones of different heights meet the critical condition of the angle between the normal and the axis when they fall over. This mechanism breaks through the limitations of traditional single-structure adaptation and ensures the success rate of resetting of the entire series of products in complex environments.
[0023] 3. The cone cap and base can be designed as separate modules. When the cone cap is damaged by external force, only the individual cone cap module needs to be replaced, avoiding the scrapping of the whole unit. The base can be reused for cone caps of any height in the same series, which greatly extends the life of the core components. At the same time, the uniform base size allows cones of different heights to be mixed and stacked for storage, optimizing the utilization of warehouse space. The modular design also expands the possibilities of functional combination, such as selecting a weighted base or a high-visibility cone cap for specific scenarios. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0035] like Figure 1 , 2 As shown in Figures 3, 7, and 8, the traffic cone includes a cone cap 1 and an annular base 2. The maximum outer diameter of the top of the cone cap 1 is R1, and its height is H. The maximum outer diameter of the counterweight part 4 of the annular base 2 is R2 > R1. Its internal counterweight cavity 41 is filled with counterweights, satisfying that the total weight of the counterweights W1 > the weight of the cone cap W2. Furthermore, the ratio of R1, R2, and H ensures that the included angle α < 90° when the cone falls to the ground, so that the counterweight torque drives the traffic cone to reset. Example 1
[0036] like Figure 1-3 As shown, this embodiment provides a self-resetting, non-tipping traffic cone with a height of 900mm, including a cone cap 1 and an annular base 2.
[0037] The maximum outer diameter of the cone-shaped structure at the top of the cone cap 1 is R1, and the height of the cone cap 1 is H;
[0038] The annular base 2 includes an upper connecting part 3 and a lower counterweight part 4. The maximum outer diameter R2 of the counterweight part 4 is greater than the maximum outer diameter of the connecting part 3. Both the connecting part 3 and the counterweight part 4 are hollow structures, and a counterweight cavity 41 is provided inside the counterweight part 4 and the connecting part 3.
[0039] The counterweight cavity contains a counterweight and satisfies the following conditions:
[0040] Where W1 is the total weight of the counterweights, and W2 is the weight of the cone cap 1;
[0041] The traffic cone is designed such that when it falls to the ground under external force, the outer edge of the counterweight 4 and the outer edge of the cone-shaped structure at the top of the cone cap 1 are the only contact points with the ground plane. The dimensional ratio between R1, R2 and H satisfies the following: when the traffic cone falls to the ground, the angle α between the normal line A passing through the contact point of R1 and the ground and perpendicular to the ground plane and the axis line O passing through the center of R1 and R2 is less than 90°, and the center of gravity of the counterweight deviates from the contact point. Under the action of the weight of the counterweight, the traffic cone is forced to return to the upright position.
[0042] The maximum outer diameter R2 of the counterweight part 4 of the annular base 2 is a fixed value, and R1 is adapted to the center of gravity requirements of the cone cap 1 with different heights H.
[0043] The bottom of the cone cap 1 is provided with a downwardly extending connecting section 11, and the middle of the connecting part 3 located on the upper part of the annular base 2 is provided with a hollow insertion interface 21 adapted to the connecting section 11. The outer diameter of the connecting section 11 is slightly smaller than the inner diameter of the hollow insertion interface 21, so that the cone cap 1 can be detachably inserted into the annular base 2.
[0044] Dimensional design: Cone height H = 900mm, maximum outer diameter at the top R1 = 80mm, maximum outer diameter of the counterweight R2 = 355mm. The proportions of these three dimensions satisfy the following: When the cone falls, the angle α between the normal A at the contact point and the axis O is 83° < 90°, ensuring the center of gravity of the counterweight deviates from the contact point. At this time, the outer edge of the counterweight 4 touches the ground, and the counterweight pulls the cone back to its original position under the action of gravity.
[0045] Structural assembly
[0046] Cone cap 1:
[0047] Material: Engineering plastic such as PE, wall thickness 3mm, height H=900mm, maximum outer diameter of top R1=80mm.
[0048] The interior is hollow, with a connecting section 11 extending from the bottom to a height of 30mm, and an annular groove on the outer wall (not shown in the figure).
[0049] Ring-shaped base 2:
[0050] Connecting part 3: outer diameter 350mm, height 84.90mm, hollow insertion interface (21) at the top, and ribs matching the card slot on the inner wall.
[0051] Counterweight part 4: outer diameter R2=355mm, height 60mm, integrally formed with connecting part (3), and an annular counterweight cavity 41 is formed inside.
[0052] Counterweight: Inject counterweight mortar with a density of 1.8 g / cm³ into cavity 41. After solidification, W1 = 2.2 kg and cone cap W2 = 0.8 kg, satisfying W1 > W2.
[0053] When the traffic cone falls to the ground due to lateral force ( Figure 2 ):
[0054] Contact point: The top edge of the cone cap and the outer edge of the counterweight simultaneously touch the ground.
[0055] Calculation of included angle α: The angle α between the ground normal A passing through point P and the axis is 83° < 90°.
[0056] Torque analysis: The center of gravity of the counterweight shifts to the outside of the contact point, and gravity generates a counterclockwise torque, forcing the traffic cone to rotate around the point to stand upright. Example 2
[0057] Reference Figure 4-6 The difference between this embodiment and Embodiment 1 is that: the height of the cone cap 1 is H=700mm, the outer diameter of the top is R1=200mm, and the outer diameter of the counterweight is R2=355mm. The size ratio ensures that the included angle α when it falls to the ground is less than 90°.
[0058] Structural variations of cone cap 1 and ring base 2:
[0059] The cone cap 1 and the connecting part 3 are integrally formed. The counterweight part (4) is fixedly connected to the bottom of the connecting part 3. It should be noted that the integral forming can be injection molding or blow molding. The rest of the counterweight cavity structure and reset principle are the same as in Embodiment 1. Example 3
[0060] like Figure 5 As shown, in this embodiment, the cone cap height H = 500mm, the top outer diameter R1 = 220mm, and the counterweight outer diameter R2 = 355mm. When it falls over, the included angle α = < 90°.
[0061] Specifically, by limiting the height to three specifications of 500mm / 700mm / 900mm (Examples 1-3), and by specifically designing the dimensional combinations of R1 (diameter of the cone cap top) and R2 (outer diameter of the counterweight), it is ensured that all road cones of different heights meet the self-resetting condition of α<90°. This overcomes the shortcomings of traditional technologies where a single size cannot be compatible with multiple national standards (such as GB / T 23827-2009, EN 13422). The center of gravity of the counterweight deviates from the contact point, and the gravitational torque drives the road cone to automatically reset, with a reset time of <3 seconds. The use of bases with the same outer diameter ensures that road cones of all specifications can be mixed and stacked, increasing warehouse utilization by 35%.
[0062] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
