[0002] Traffic safety guidance devices are used to guide road users to pass safely. During highway maintenance and construction, it is often necessary to temporarily close or divert roads. For safety reasons, traffic safety guidance devices need to be installed in the construction sections to remind vehicles and pedestrians of safety precautions and road detours.

[0003] Existing traffic safety guidance devices are installed on the road surface using brackets. This installation method generally requires bolts for fixing, which can easily damage the road surface. Alternatively, traffic safety guidance devices can be installed on guardrails using bolts and other fasteners. These two installation methods are generally not interchangeable. During highway construction, construction personnel need to select the appropriate safety guidance device based on the site conditions. Therefore, installation may be inconvenient.

[0004] Therefore, this application proposes a traffic safety guidance device for highway maintenance construction to improve the ease of installation. Utility Model Content

[0036] like Figures 1-3 As shown, this utility model provides a traffic safety guidance device for highway maintenance construction, including an indicating mechanism 1 and a support mechanism 2. The indicating mechanism 1 and the support mechanism 2 are installed together in a detachable manner. During installation, the supporting mechanism 2 can be used to support the indicating mechanism 1 on the ground, giving the indicating mechanism 1 a certain height. After the support mechanism 2 is disassembled, the indicating mechanism 1 can be installed separately on a fence or a supporting surface, improving the convenience of installation through various installation methods.

[0037] Specifically, the signage mechanism 1 includes a sign 11, on which traffic guidance markings are displayed. Two support frames 13 are symmetrically arranged at the bottom of the back of the sign 11, about its central axis. Each support frame 13 has an n-shaped end, on which a fastening key 14 is mounted. The n-shaped structure can be secured to the upper edge of a construction site fence, and the sign 11 can be installed on the fence by engaging the fastening key 14 with the support frame 13.

[0038] The bottom of the indicator 11 has a support rod mounting hole 12 at its center. The support rod mounting hole 12 is threadedly connected to the support mechanism 2, thereby allowing the support mechanism 2 to be easily assembled and disassembled.

[0039] like Figure 3 As shown, in some embodiments, the bottom of all support frames 13 of this invention is flush with the bottom of the sign 11. When the sign 11 is placed on a flat surface, the sign 11 can be supported by the support frames 13, thereby allowing the sign 11 to stand upright on the support surface. The bottom of the support frame 13 has a support hole 131, and the support frame 13 can be further fixed by screws passing through the support hole 131, improving the stability of the sign 11 support.

[0040] like Figure 1 and Figure 2As shown, in some embodiments, the sign 11 of this utility model is an LED screen. A power supply 15 is disposed between the two support frames 13 on the back of the sign 11. The power supply 15 is powered by a battery or photovoltaic device, thereby enabling the display of traffic signs on the sign 11. The power supply 15 is provided with a data interface, allowing an external PC device to configure the signs displayed on the sign 11 via a data cable, thereby expanding the applicability of the sign 11.

[0041] like Figure 4 As shown, in some embodiments, the support mechanism 2 of this utility model includes a counterweight base 21. The counterweight base 21 has a through hole for cooperating with anchors to fix the counterweight base 21 to the ground. A first support rod 22 is mounted on the axis at the top of the counterweight base 21, and a second support rod 23 is mounted on the top of the first support rod 22. The first support rod 22 and the second support rod 23 cooperate to support the indicator sign 11, ensuring the indicator sign 11 is at a suitable height. A threaded post 24 is provided at the upper end of the second support rod 23, and the threaded post 24 is threadedly connected to the support rod mounting hole 12, allowing for easy assembly and disassembly of the second support rod 23 from the indicator sign 11.

[0042] like Figure 1 and Figure 4 As shown, in some embodiments, the bottom of the second support rod 23 of this invention is provided with a support platform 25 extending to both sides. The top of the support platform 25 overlaps with the bottom of the sign 11, thereby supporting the sign 11 through the support platform 25 to improve the stability of the sign 11.

[0043] like Figure 4 As shown, in some embodiments, the bottom of the support platform 25 of this invention is provided with a rounded chamfer to avoid the edges of the support platform 25 being too sharp. When an electric vehicle driver or a car driver is distracted and collides with the support platform 25, the damage caused to people and vehicles by the support platform 25 can be reduced.

[0044] like Figure 5 As shown, in some embodiments, the second support rod 23 of this invention is inserted inside the first support rod 22, and the second support rod 23 can extend upward. When a car passes under the support platform 25, the car's tilted A-pillar and windshield will exert an impact force on the support platform 25 at an angle. At this time, the second support rod 23 will rise under the action of the impact force, allowing the vehicle to pass through, thereby reducing damage to the equipment and the vehicle.

[0045] like Figure 6As shown, in some embodiments, the first support rod 22 of this invention has a telescopic cavity 221 inside. A telescopic rod 231 is axially mounted at the bottom of the second support rod 23, extending into the telescopic cavity 221. The cooperation between the telescopic rod 231 and the telescopic cavity 221 allows the second support rod 23 to rise along a predetermined trajectory. A slider is provided at the bottom of the telescopic rod 231, which limits the telescopic rod 231 within the telescopic cavity 221 to prevent it from rising excessively and detaching from the cavity.

[0046] like Figure 6 As shown, in some embodiments, the diameter of the telescopic rod 231 is smaller than the inner diameter of the telescopic cavity 221, and an elastic support member 232 is sleeved on the outer surface of the telescopic rod 231. The elastic support member 232 applies pressure to the slider so that the bottom of the second support rod 23 abuts against the top of the first support rod 22, thereby improving the stability of the connection between the first support rod 22 and the second support rod 23.

[0047] like Figure 5 As shown, in some embodiments, a limiting groove 222 is provided on the top of the outer surface of the first support rod 22 of this invention. A limiting block 233 is provided on the bottom edge of the second support rod 23. The limiting block 233 is inserted into the limiting groove 222, thereby limiting the angle of the second support rod 23 and preventing the sign 11 from rotating after being exposed to wind, thus improving the accuracy of the direction indicated by the sign 11.

[0048] In summary, the traffic safety guidance device for highway maintenance construction of this utility model, by setting a support rod mounting hole 12 at the bottom of the sign 11, and connecting the support rod mounting hole 12 to the support mechanism 2, allows the sign 11 to be installed on the road surface through the support mechanism 2. When the support mechanism 2 is disassembled, it can be clipped onto the fence by the support frame 13 and fixed by the fastening key 14. Furthermore, the sign 11 can also be fixed to the plane by the support hole 131 and the screw. This method can be adapted to the construction environment, thereby improving the ease of installation.

[0049] This utility model provides a support platform 25 at the top of the second support rod 23 to support the sign 11, thereby improving the stability of the sign 11. Furthermore, by providing rounded corners at the bottom of the support platform 25, the damage caused to pedestrians after impact is reduced.

[0050] This invention inserts a second support rod 23 into the interior of a first support rod 22, thereby allowing the second support rod 23 to rise. When the bottom of the support platform 25 is impacted in an inclined direction, the second support rod 23 can rise slightly to reduce the impact force of the collision and improve the safety of the equipment.

[0051] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0052] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
