DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The utility model provides a traffic cone 100, which can facilitate the stacking of the traffic cones 100, thereby improving the efficiency of the folding and unfolding operation of the traffic cones 100.

[0029] Reference Figures 1 to 5 According to the traffic cone 100 of the embodiment of the utility model, the traffic cone 100 includes a base 10 and a cone 20, the base 10 has a lower supporting surface 11 and an upper supporting surface 12, the upper supporting surface 12 includes a first surface 121 and a second surface 122, at least a portion of the first surface 121 is higher than the second surface 122, in the orthographic projection along the up and down direction, the lower supporting surface 11 is located on the second surface 122, and the inner periphery of the lower supporting surface 11 is located on the outer side of the first surface 121, the cone 20 is connected to the base 10, wherein, when the traffic cones 100 are stacked, the lower supporting surface 11 is arranged on the second surface 122 and is limited by the first surface 121; in this arrangement, through the cooperation of the first surface 121 and the second surface 122, the stacking of the traffic cones 100 can be facilitated, thereby improving the efficiency of the folding and releasing operation of the traffic cones 100.

[0030] For example, the second surface 122 is arranged radially outside the first surface 121. When two traffic cones 100 are stacked, the cone 20 of one traffic cone 100 is sleeved with the cone 20 of the other traffic cone 100. The lower support surface 11 of the base 10 of one traffic cone 100 is arranged on the second surface 122 of the upper support surface 12 of the base 10 of the other traffic cone 100. The inner periphery of the lower support surface 11 is located radially outside the first surface 121 of the upper support surface 12 of the base 10 of the other traffic cone 100, and is supported by the other traffic cone. The first surface 121 of the upper supporting surface 12 of the base 10 of the traffic cone 100 limits the lower supporting surface 11 of one traffic cone 100, thereby limiting the movement of one traffic cone 100; in other words, through the inner periphery of the lower supporting surface 11 of one traffic cone 100 cooperating with the first surface 121 and the second surface 122 of another traffic cone 100, the lower supporting surface 11 of the traffic cone 100 is limited by the first surface 121, so that the two traffic cones 100 can be positioned relative to each other when stacked, thereby preventing the traffic cones 100 from being loosened when stacked, thereby affecting the efficiency of the retracting and releasing operation of the traffic cones 100.

[0031] In addition, during the stacking process, since at least a portion of the first surface 121 is higher than the second surface 122, when the traffic cones 100 are stacked, the first surface 121 of one traffic cone 100 can guide the inner periphery of the lower supporting surface 11 of another traffic cone 100 to overlap on the second surface 122, so as to improve the stacking stability.

[0032] Reference Figures 1 to 3 In some embodiments of the present invention, the first surface 121 includes a guide surface 1211 that is inclined downward from the inside to the outside in the radial direction of the base 10; specifically, when two traffic cones 100 are stacked, the inner circumference of the lower support surface 11 of one traffic cone 100 can contact the first surface 121 of the other traffic cone 100, and the first surface 121 includes a guide surface 1211 that is inclined downward from the inside to the outside in the radial direction of the base 10, thereby guiding the inner circumference of the lower support surface 11 of one traffic cone 100 to overlap on the second surface 122 of the other traffic cone 100, so as to facilitate the stacking of the traffic cones 100.

[0033] Reference Figures 1 to 3In some embodiments of the utility model, the first surface 121 also includes a stop surface 1212 extending along the axial direction of the base 10, and the stop surface 1212 is respectively connected to the guide surface 1211 and the second surface 122 to construct a step structure; specifically, when two traffic cones 100 are stacked, the inner periphery of the lower supporting surface 11 of one traffic cone 100 can be guided by the guide surface 1211 of the upper supporting surface 12 of the other traffic cone 100 and formed on the second surface 122, and is restricted by the stop surface 1212 of the upper supporting surface 12 of the other traffic cone 100 to achieve the limiting of the traffic cone 100; in other words, the two traffic cones 100 can be guided to be stacked together through the step structure, and the two traffic cones 100 can be prevented from detaching.

[0034] Reference Figures 1 to 3 In other embodiments of the present invention, the first surface 121 also includes a supporting surface 1213 extending radially along the base 10, and the supporting surface 1213 can be used to support the cone 20 of the traffic cone 100. It can be understood that the traffic cone 100 includes the cone 20 and the base 10, and the cone 20 is arranged on the base 10. The second surface 122 of the base 10 can be used to support the inner periphery of the lower supporting surface 11 of another traffic cone 100, and the supporting surface 1213 can be used to support the bottom of the cone 20, thereby improving the stacking stability of the traffic cone 100.

[0035] In addition, the guide surface 1211 is respectively connected to the supporting surface 1213 and the second surface 122. The base 10 has a through hole 13. The lower end of the through hole 13 is the inner periphery of the lower supporting surface 11 of the base 10. In the bottom-up direction, the inner wall surface of the through hole 13 is inclined toward the radial inner side of the base body. In this way, the inner wall surface of the through hole 13 can be adapted to the guide surface 1211 to improve the stacking stability.

[0036] In some embodiments of the present invention, the guide surface 1211 is configured as a curved surface, which can reduce stress concentration and improve the structural stability and durability of the guide surface 1211. Alternatively, the guide surface 1211 is configured as a flat surface, which can reduce the processing and manufacturing cost of the guide surface 1211.

[0037] Reference Figure 1 and Figure 2 In some embodiments of the utility model, the base 10 has a through hole 13, and the outer peripheral surface of the cone 20 is connected to the edge portion of the through hole 13; wherein, the inner peripheral wall of the through hole 13 is provided with a positioning portion 131, and the outer peripheral surface of the cone 20 is provided with a positioning groove 21, and the positioning portion 131 is engaged with the positioning groove 21; in this way, the assembly of the cone 20 and the base 10 can be realized, and the installation stability can be improved.

[0038] Specifically, the cone 20 can be inserted into the through hole 13 of the base 10, and the lower end of the cone 20 can be connected to the inner wall surface of the through hole 13; wherein, the inner circumferential wall of the through hole 13 is provided with a positioning portion 131, and the outer circumferential surface of the cone 20 is provided with a positioning groove 21, and the positioning portion 131 and the positioning groove 21 both extend along the radial direction of the base body; during assembly, the cone 20 can pass through the through hole 13 from one side and pass through the through hole 13 from the other side, so that the positioning portion 131 on the inner wall surface of the through hole 13 can be embedded in the positioning groove 21 on the outer circumferential surface of the lower end of the cone 20, thereby connecting the cone support to the base 10 to realize the assembly of the traffic cone 100.

[0039] Further, refer to Figure 1 and Figure 2 In some embodiments of the utility model, the outer circumferential surface of the cone 20 includes a first positioning protrusion 22 and a second positioning protrusion 23 arranged from top to bottom, and a positioning groove 21 is constructed between the first positioning protrusion 22 and the second positioning protrusion 23; wherein, the outer circumferential surface of the first positioning protrusion 22 is inclined from top to bottom in a direction away from the cone 20, so that the assembly of the cone 20 and the base 10 can be facilitated, thereby improving the assembly efficiency of the traffic cone 100.

[0040] In detail, during assembly, the upper end of the cone 20 can be passed through one side of the through hole 13 and out from the other side of the through hole 13, and the positioning portion 131 on the inner wall of the through hole 13 can be embedded between the first positioning protrusion 22 and the second positioning protrusion 23 to achieve the assembly of the cone 20 and the base 10; in this process, since the outer peripheral surface of the first positioning protrusion 22 is inclined from top to bottom in the direction away from the cone 20 to form a guiding structure, the outer peripheral surface of the first positioning protrusion 22 can guide the positioning portion 131 to be embedded between the first positioning protrusion 22 and the second positioning protrusion 23 to improve the assembly efficiency of the cone 20.

[0041] Reference Figure 1 and Figure 2 In some embodiments of the utility model, the base 10 includes a first base body 14 and a second base body 15, the lower surface of the first base body 14 is configured as a lower support surface 11, the second base body 15 is arranged on the first base body 14 and is higher than the upper surface of the first base body 14, and the upper surface of the second base body 15 is configured as an upper support surface 12; such a configuration can facilitate the retraction and release of the traffic cone 100 and avoid the traffic cone 100 from getting stuck.

[0042] Specifically, the second seat body 15 is disposed on the first seat body 14 and is higher than the upper surface of the first seat body 14. In other words, the upper surface of the second seat body 15 is higher than the upper surface of the first seat body 14. When the upper surface of the second seat body 15 supports the traffic cone 100, the traffic cone 100 can be separated from the upper surface of the first seat body 14 by a predetermined distance, so as to increase the spacing between the bases 10 of two adjacent stacked traffic cones 100 and avoid the traffic cones 100 from getting stuck. In this way, when the traffic cones 100 are retracted or released, the clamping device can extend between the two adjacent stacked traffic cones 100, thereby taking out and placing the traffic cones 100, thereby improving the efficiency of the retracting and releasing operation.

[0043] Reference Figures 1 to 4 In some embodiments of the present invention, in the orthographic projection along the up-down direction, at least a portion of the second base body 15 is disposed inside the outer periphery of the first base body 14, so that the space occupied by the base 10 of the traffic cone 100 can be reduced, thereby improving the space utilization rate when the traffic cones 100 are stacked.

[0044] Furthermore, the second seat body 15 is arranged on the inner side of the outer periphery of the first seat body 14; for example, in the direction from the radial inside to the radial outside of the base 10, the radial dimension of the outer periphery of the second seat body 15 is smaller than the radial dimension of the outer periphery of the first seat body 14, thereby further reducing the space occupied by the traffic cone 100.

[0045] Reference Figure 1 and Figure 2 In some embodiments of the utility model, a positioning boss 141 is provided on the upper surface of the first seat body 14, and a positioning groove is provided on the lower surface of the second seat body 15. The positioning boss 141 and the positioning groove are arranged around the circumference of the seat body, and the positioning boss 141 and the positioning groove are engaged with each other; in this way, the second seat body 15 of different sizes can be replaced according to needs to meet the anti-jamming requirements of the traffic cone 100.

[0046] Specifically, the upper surface of the first seat body 14 includes a third surface, a fourth surface and a fifth surface, the third surface and the fifth surface extend along the radial direction of the base 10 and are arranged around the through hole 13, the fourth surface extends along the axial direction of the base 10 and is arranged around the through hole 13, and is respectively connected with the third surface and the fifth surface to form a positioning boss 141; the lower surface of the second seat body 15 includes a sixth surface, a seventh surface and an eighth surface, the sixth surface and the eighth surface extend along the radial direction of the base 10 and are arranged around the through hole 13, the seventh surface extends along the axial direction of the base 10 and is arranged around the through hole 13, and is respectively connected with the sixth surface and the eighth surface to form a positioning groove; when the first seat body 14 and the second seat body 15 are assembled, the third surface corresponds to the sixth surface, the fourth surface corresponds to the seventh surface, and the fifth surface corresponds to the eighth surface, so that the positioning boss 141 is embedded in the positioning groove to achieve assembly.

[0047] In some other embodiments of the present invention, the first base body 14 and the second base body 15 are connected by bonding; it can be understood that connecting the first base body 14 and the second base body 15 together by bonding can effectively reduce the weight of the traffic cone 100, and absorb vibration through the bonding layer between the first base body 14 and the second base body 15 to improve the structural stability of the traffic cone 100.

[0048] Reference Figure 4 In some embodiments of the present invention, in the orthographic projection along the up-down direction, the outer periphery of the base 10 is configured as a polygon to improve the stability of the traffic cone 100 .

[0049] Generally, in the orthographic projection along the up-down direction, the outer periphery of the base 10 of the traffic cone 100 is circular. The base 10 of the traffic cone 100 with such a structure is easily blown by the wind when the traffic cone 100 is tipped over, thereby rolling on the road surface, which is inconvenient for the traffic cone 100 to be retracted and deployed. Therefore, in the orthographic projection along the up-down direction, the outer periphery of the base 10 of the traffic cone 100 can be constructed as a polygon, so that the traffic cone 100 can be stably placed on the road surface when tipped over, and the traffic cone 100 can be prevented from being blown away by the wind.

[0050] Reference Figure 4 In some embodiments of the present invention, a plurality of weight-reducing grooves 16 are constructed at the bottom of the base 10, and the plurality of weight-reducing grooves 16 are arranged along the circumference of the base 10; specifically, the lower supporting surface 11 of the base 10 is recessed upward to form a plurality of weight-reducing grooves 16, and the plurality of weight-reducing grooves 16 are arranged around the circumference of the base 10, thereby reducing the weight of the traffic cone 100 and reducing the material cost of the traffic cone 100.

[0051] A reinforcing rib 17 is provided in the weight-reducing groove 16. The reinforcing rib 17 extends along the radial direction of the base 10. The reinforcing rib 17 can be connected to the outer periphery of the base 10 and the inner periphery of the base 10 respectively, thereby improving the structural strength of the base 10 of the traffic cone 100; in addition, the reinforcing rib 17 includes a plurality of reinforcing ribs, and the plurality of reinforcing ribs 17 are respectively arranged in the corresponding weight-reducing groove 16, thereby further enhancing the structural strength of the base 10 of the traffic cone 100.

[0052] Reference Figure 5In some embodiments of the present invention, the lower support surface 11 of the base 10 includes a first part and a second part, the first part is recessed upward so that the second part forms a reinforcement surface 18 relative to the first part, and the reinforcement surface 18 is connected to the outer periphery of the base 10; specifically, a part of the lower support surface 11 of the base 10 is recessed upward so that the other part forms a reinforcement surface 18, and the reinforcement surface 18 is connected to the outer periphery of the base 10, and can be constructed as a rectangle matching the push rod; it can be understood that during the recovery process of the traffic cone 100, the traffic cone 100 can be placed in the box by the clamping mechanism, and the traffic cone 100 can be pushed into the box by the push rod of the push rod mechanism. By constructing a shape matching the push rod at the bottom of the base 10 of the traffic cone 100, the stability of the traffic cone 100 can be improved, thereby improving the efficiency of the traffic cone 100. And the upward recessed part of the lower support surface 11 of the base 10 can be the aforementioned weight reduction groove 16 to reduce the weight of the traffic cone 100.
