Description

Technical Field

[0001] The utility model relates to the technical field of highways, in particular to a highway construction warning sign. Background Art

[0002] In the current market environment, warning signs are widely used in various occasions, especially in highway construction, where they play a vital role in safety and warning. However, traditional warning sign designs often pursue large sizes to enhance their warning effects. Such designs do enhance the significance of warnings to a certain extent, but they also bring a series of problems.

[0003] First, when encountering strong winds, large-sized warning signs are easily blown down by the wind due to their large wind-exposed area, which not only affects the warning effect, but also may cause safety hazards to the surrounding environment. In addition, the toppling of warning signs caused by strong winds may also pose a threat to construction workers and passing vehicles, which undoubtedly increases safety risks. Secondly, large-sized warning signs require more space during transportation and storage. This not only increases logistics costs, but also increases the demand for storage space, bringing considerable challenges to construction management and logistics arrangements. This inconvenience is particularly obvious in scenarios such as highway construction where frequent transfers of work locations are required.

[0004] Chinese patent CN219364390U discloses a warning sign for highway construction that is easy to store. This design does realize the extension and deployment function of the warning sign, and improves the flexibility of use. However, its wind resistance is not ideal, and it is still easy to fall down in the case of slightly strong winds, which not only affects the normal use of the warning sign, but also may bring safety hazards.

DETAILED DESCRIPTION

[0020] 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. The utility model is further described in combination with the drawings and embodiments:

[0021] like Figure 1-Figure 4 As shown, a highway construction warning sign includes a bottom box 1, a spherical groove 14 is formed in the middle of the bottom box, a semi-spherical shell 21 is rotatably connected in the spherical groove, and a counterweight is placed at the bottom of the semi-spherical shell. Such a design allows the warning sign to rotate 360 ​​degrees, and the counterweight can maintain its stability. A conical shell 22 is provided on the top of the semi-spherical shell, and a threaded sleeve 23 is provided on the top of the conical shell. The threaded sleeve is threadedly connected to a central axis 3. Such a structure can easily adjust the height of the central axis to adapt to different usage scenarios. A left warning sign 6 and a right warning sign 7 are rotatably connected to the central axis, and two sets of spring reset mechanisms are installed on the central axis. The double warning sign design can increase the display area of ​​the warning information, and the spring reset mechanism can ensure that the warning sign always maintains the correct display angle.

[0022] Furthermore, the two sets of spring return mechanisms can drive the left warning sign 6 and the right warning sign to always be in the same plane. Even if there is a strong wind that causes the two to rotate around the central axis, the two can be kept parallel again with the help of the flexible spring. This design can ensure that the warning sign can still clearly display information in severe weather such as strong winds.

[0023] Further, the two groups of spring return mechanisms are respectively located at the top and bottom of the left warning sign 6 and the right warning sign 7. The upper and lower groups of spring return mechanisms can more comprehensively maintain the stability of the warning sign.

[0024] In at least one embodiment, the spring reset mechanism includes a fixed plate 83, a first plate 81 is provided on the left warning sign, a second plate 85 is provided on the right warning sign, a first flexible spring 82 is provided between the fixed plate and the first plate, and a second flexible spring 84 is provided between the fixed plate and the second plate. This spring reset mechanism is simple and effective in design, and can ensure that the warning sign quickly returns to its original state after being acted upon by an external force.

[0025] In at least one embodiment, an annular water storage chamber 11 is formed in the bottom box, a water inlet pipe 12 is provided at the top of the annular water storage chamber, and a water outlet pipe 13 is provided at the bottom of the annular water storage chamber. The design of the annular water storage chamber can increase the weight of the bottom box, further improve the stability of the warning sign, and the weight of the warning sign can also be changed by adjusting the water volume.

[0026] In at least one embodiment, the bottom of the bottom box is provided with a mounting notch 16, and an insertion notch 15 is formed between the mounting notch and the spherical groove. This design can facilitate the installation and removal of the warning sign, thereby improving the use efficiency.

[0027] In coordination with this, a hemispherical bottom plate 4 is inserted into the insertion slot, and the hemispherical bottom plate is connected to a lower connecting plate 5, and the lower connecting plate is fixedly connected to the threaded hole in the installation slot by bolts. This connection method is both firm and convenient to disassemble, and is convenient for maintenance and replacement.

[0028] Working method: insert the hemispherical bottom plate into the insertion slot of the bottom box, and use bolts to fix the lower connecting plate in the threaded hole in the installation slot to ensure the stability of the entire device. Place a counterweight at the bottom of the hemispherical shell to maintain the stability of the warning sign and ensure that the hemispherical shell can rotate flexibly in the spherical slot. The height of the central axis is adjusted by the threaded sleeve to adapt to different scenarios and needs. The left and right warning signs can rotate freely around the central axis and remain in a parallel state through the spring reset mechanism. Under the action of external forces such as strong winds, if the left and right warning signs rotate, the spring reset mechanism will play a role. The first flexible spring and the second flexible spring in the spring reset mechanism will drive the left and right warning signs back to a parallel state to ensure that the warning information is clear and visible. Water can be injected into the annular water storage cavity through the water inlet pipe to increase the weight of the bottom box and further improve stability. When it is necessary to move or change the position, the water in the annular water storage cavity can be discharged through the water outlet pipe for easy transportation.

[0029] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model.
