Description

Technical Field

[0001] The utility model relates to the technical field of traffic construction, in particular to a wind-resistant traffic construction warning sign. Background Art

[0002] Traffic construction warning signs are construction signs, which are a type of traffic warning signs. They are usually placed in a suitable position in front of the construction site to inform passers-by that there is construction ahead and that they should slow down or take a detour for safety to reduce the occurrence of safety accidents. There are four types of safety signs at construction sites: prohibition signs: red, indicating that certain behaviors are not allowed or stopped; warning signs: yellow, alerting people to possible dangers; instruction signs: blue, indicating that they must be followed and used to force or restrict people's behavior; instruction signs: green, indicating locations or directions.

[0003] Current traffic construction warning signs generally have a simple structure, usually consisting of a support frame and a sign body, with warning content printed on the front side of the sign. However, due to the large sign area and light overall structure, it is difficult to stably fix the warning sign on the ground when used in windy weather. The larger sign will bear a greater wind load, making the warning sign prone to overturning and falling sideways, making it inconvenient to use. Therefore, improvements are now being made to traffic construction warning signs. Utility Model Content

[0025] See also Figure 1-2In the present embodiment, a wind-resistant traffic construction warning sign is provided, including a warning sign body 1 and an adjustable bracket 2, the warning sign body 1 including a frame 11, a panel 12 is fixedly arranged on the front side of the frame 11, a support bar 13 fixedly connected to the frame 11 is arranged on the rear side of the panel 12, a plurality of neatly arranged triangular through grooves 121 are opened on the panel 12, and a flip structure 3 is arranged at the position where the triangular through grooves 121 are opened on the rear side of the panel 12, wherein the panel 12 is used to display the warning content, when the wind load borne by the panel 12 reaches a certain level, under the push of the wind, the flip structure 3 will flip open, so that the triangular through grooves 121 can allow airflow to pass, thereby reducing the overall area of ​​the panel 12, so that the thrust from the wind on the panel 12 is greatly reduced, thereby improving the overall wind resistance of the warning sign.

[0026] Specifically, refer to Figure 3-4 The flip structure 3 includes a flip hinge seat 31 and a triangular flip piece 32 fixedly connected to the rear side of the panel 12, and a connecting plate 33 is fixedly arranged on the rear end surface of the triangular flip piece 32. The connecting plate 33 is rotatably connected to the flip hinge seat 31 through a rotating shaft 34 fixedly connected at both ends, and the rotating shaft 34 is located between the connecting plate 33 and the flip hinge seat 31. A return torsion spring 35 is provided on the shaft section outer sleeve, one end of the return torsion spring 35 is fixedly connected to the connecting plate 33, and the other end of the return torsion spring 35 is fixedly connected to the flip hinge seat 31. When the wind load reaches a certain level, the airflow will push the triangular flip piece 32 to rotate around the rotating shaft 34 as the central axis, so that the triangular through groove 121 usually covered by the triangular flip piece 32 is opened, and the airflow can flow away through the opened triangular through groove 121, so that the wind load on the panel 12 as a whole is greatly reduced. When the wind intensity decreases, the triangular flip piece 32 will rotate back to its original position under the action of the return torsion spring 35, thereby ensuring the integrity of the panel 12 most of the time.

[0027] Specifically, refer to Figure 3-4 The triangular flip sheet 32 ​​is made of the same material as the panel 12, and the shape and size of the triangular flip sheet 32 ​​are consistent with the shape and size of the triangular through groove 121. This structural form can ensure that when the triangular flip sheet 32 ​​is not flipped, the front side of the panel 12 has a high integrity, which is convenient for displaying the warning content.

[0028] Specifically, refer to Figure 6The adjustable bracket 2 includes vertical support rods 21 fixedly connected to both sides of the lower end surface of the frame 11 respectively, and the bottom ends of the vertical support rods 21 are hinged to the upper end surface of the front end of the bottom support rod 23 through the first hinge seat 22. A horizontal connecting rod 241 is fixedly connected between the rear ends of the bottom support rod 23, and a counterweight block 24 is provided on the outer sliding sleeve of the middle part of the horizontal connecting rod 241. The above-mentioned structural form can make the overall angle of the warning sign body 1 adjustable by hinged connection between the vertical support rod 21 and the bottom support rod 23, which is convenient for the use of the overall structure. At the same time, the combination of the counterweight block 24 and the bottom support rod 23 extending backward can greatly improve the anti-overturning ability of the overall structure, so that no matter which direction it overturns, a large bending moment is required.

[0029] Specifically, refer to Figure 6 , diagonal support rods 26 are hinged on both sides of the rear end surface of the frame 11 through the second hinge seat 25, and a fixing plate 27 is hinged on the bottom end of the diagonal support rod 26. Through bolt holes 28 are provided on the front and rear ends of the fixing plate 27. A row of bolt holes 28 are provided on the upper end surface of the bottom support rod 23. The fixing plate 27 is fixedly connected to the bottom support rod 23 by threading the fixing bolts 29 with the bolt holes 28. The above-mentioned structural form can adjust the overall inclination angle of the warning sign body 1 by fixing the fixing plate 27 and the bottom support rod 23 at different positions.

[0030] Specifically, refer to Figure 6 The spacing between the bolt holes 28 on the fixing plate 27 is equal to the spacing between any two adjacent bolt holes 28 in a row of bolt holes 28 opened on the upper end surface of the bottom support rod 23. The above-mentioned structural form can ensure that the fixing plate 27 can be effectively connected with any two adjacent bolt holes 28 in a row of bolt holes 28 opened on the upper end surface of the bottom support rod 23, thereby improving the convenience of the overall structure when in use.

[0031] Working principle: When the wind load reaches a certain intensity, the airflow will push the triangular flip sheet 32 ​​to rotate with the rotating shaft 34 as the central axis, so that the triangular slot 121 usually covered by the triangular flip sheet 32 ​​is opened, and the airflow can flow through the opened triangular slot 121, so that the wind load on the panel 12 as a whole is greatly reduced, thereby improving the overall wind resistance of the warning sign, and when the wind intensity decreases, the triangular flip sheet 32 ​​will rotate back to its original position under the action of the reset torsion spring 35, thereby ensuring the integrity of the panel 12 most of the time, so as to fully display the warning content printed on the panel 12;

[0032] In addition, the combination of the counterweight block 24 and the bottom support rod 23 extending backward can greatly improve the overall anti-overturning ability of the structure, so that a large bending moment is required to prevent the warning sign from overturning in any direction, making the warning sign as a whole have a strong anti-overturning ability, thereby further improving the overall wind resistance of the warning sign.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
