[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 , an embodiment provided by the utility model:

[0025] A highway sign for reducing wind resistance, comprising:

[0026] The main body includes a column 1, the top of which is fixedly connected to a base 11, and a guide sign 12 is arranged on the top of the column 1;

[0027] The wind resistance reduction mechanism includes a fixed frame 2, which is fixedly connected to the surface of the column 1, a rotating rod 21 is fixedly connected to the surface of the guide sign 12, and the rotating rod 21 is rotatably connected to the fixed frame 2. A base frame 22 is fixedly connected to the bottom of the fixed frame 2, a spring 23 is fixedly connected to the surface of the base frame 22, a limiting plate 24 is fixedly connected to the surface of the spring 23, a guide rod 25 is fixedly connected to the surface of the limiting plate 24, and the guide rod 25 is slidably connected to the surface of the base frame 22. A vent 26 is provided on the surface of the guide sign 12. The wind resistance reduction mechanism can reduce the influence of wind on the guide sign 12, ensure the stability of the guide sign 12 on the column 1, and ensure the normal operation of the guide sign 12 on the column 1.

[0028] Furthermore, a counterweight mechanism is provided on the surface of the column 1, and the counterweight mechanism includes a support frame 3, the support frame 3 is fixedly connected to the surface of the column 1, a limit rod 31 is snap-connected on the surface of the support frame 3, a counterweight box 32 is fixedly connected to the surface of the limit rod 31, a bolt 33 is threadedly connected to the surface of the support frame 3, and a lifting ear 34 is fixedly connected to the top of the counterweight box 32. The existing guide sign 12 is usually installed on one side of the column 1. In some areas with soft geology, the guide sign 12 is heavy and will cause the column 1 to tilt. The counterweight mechanism can maintain the stability of the column 1 and prevent the column 1 from tilting.

[0029] Furthermore, the rotating rod 21 is fixedly connected to both sides of the top of the guide sign 12. The fixed frame 2 is in the shape of a "mouth". A circular groove is provided on the top of the fixed frame 2. The rotating rod 21 rotates on the circular groove of the fixed frame 2. The guide sign 12 rotates on the top of the fixed frame 2 through the rotating rod 21. When strong wind blows onto the guide sign 12, the guide sign 12 will change the inclination angle of the guide sign 12 by rotating on the fixed frame 2, thereby reducing the wind force received by the guide sign 12.

[0030] Furthermore, the base frame 22 is in an "L" shape, and a guide hole is opened on the surface of the base frame 22. The guide rod 25 slides on the guide hole of the base frame 22, and the guide rod 25 drives the limit plate 24 to move horizontally on the surface of the base frame 22. The limit plate 24 is provided with two groups. The two groups of limit plates 24 are squeezed on both sides of the bottom of the guide sign 12 under the elastic force of the spring 23. The limit plates 24 limit the rotation of the guide sign 12 on the fixed frame 2, so that the guide sign 12 is in a vertical state as a whole. When the guide sign 12 rotates, the guide sign 1 The limiting plate 24 on one side is squeezed, so that the limiting plate 24 drives the guide rod 25 to slide on the guide hole of the bottom frame 22, and the spring 23 is squeezed and deformed. When there is no strong wind, the elastic force of the spring 23 will drive the limiting plate 24 to squeeze the guide road sign 12 to be vertical. The guide road sign 12 is always in contact with the limiting plate 24 during the rotation process, and the limiting plate 24 cannot slide out of the bottom frame 22. The guide road sign 12 is always limited in its rotation angle during the rotation process, ensuring that the driver can always guide the sign on the road sign 12.

[0031] Furthermore, multiple groups of vents 26 are provided, and the vents 26 are evenly arranged in a rectangular shape on the surface of the guide sign 12. Strong winds will pass through the guide sign 12 through the vents 26, thereby reducing the wind resistance of the guide sign 12. At the same time, the vents 26 are small in size and will not affect the signposts on the guide sign 12.

[0032] Furthermore, the support frame 3 is in an "L" shape, and a "T"-shaped groove is provided on the surface of the support frame 3. The limit rod 31 is in a "T" shape, and the limit rod 31 is snap-connected to the "T"-shaped groove of the support frame 3. The height of the limit rod 31 is less than the height of the "T"-shaped groove of the support frame 3. The limit rod 31 limits the counterweight box 32 on the surface of the support frame 3, thereby limiting the counterweight box 32 to the top of the column 1, and the counterweight box 32 is on the opposite side of the guide sign 12. The lifting ear 34 on the counterweight box 32 facilitates the crane to lift the counterweight box 32.

[0033] Furthermore, a threaded hole is opened at the top of the support frame 3, and a bolt 33 is threadedly connected to the threaded hole of the support frame 3. The threaded hole of the support frame 3 is connected to the "T"-shaped groove of the support frame 3. The bolt 33 limits the position of the counterweight box 32 on the support frame 3, so that the counterweight box 32 is installed on the surface of the support frame 3.

[0034] Working principle: When the guide sign 12 is subject to strong winds, the guide sign 12 will rotate on the fixed frame 2 through the rotating rod 21. The guide sign 12 reduces the wind resistance of the guide sign 12 by changing the inclination angle. At the same time, the vents 26 on the fixed frame 2 can allow wind to pass through, which also reduces the wind resistance of the guide sign 12. During the rotation process, the guide sign 12 will drive the limit plate 24 and the guide rod 25 to slide on the base frame 22, and cause compression deformation to the spring 23. The limit plate 24 limits the rotation angle of the guide sign 12 on the fixed frame 2, ensuring that the road signs on the guide sign 12 can be clearly seen by the driver. When the wind force decreases, the spring 23 uses the elastic force to cause the limit plate 24 to squeeze the guide sign 12, so that the guide sign 12 rotates to be perpendicular to the horizontal plane.

[0035] The counterweight box 32 is lifted by the lifting ear 34, and the limit rod 31 is engaged and connected to the groove of the support frame 3. The limit rod 31 limits the counterweight box 32 on the surface of the support frame 3. At this time, the bolt 33 is rotated on the threaded hole of the support frame 3 so that the bolt 33 limits the position of the limit rod 31 on the support frame 3 in the groove of the support frame 3, thereby completing the installation of the counterweight box 32 on the support frame 3. The counterweight box 32 is on the opposite side of the guide sign 12, so that the entire column 1 is in a balanced state, avoiding the guide sign 12 from driving the column 1 to tilt, and improving the stability of the column 1.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
