[0002] During highway construction, safety guidance equipment is usually set up around the construction area to remind vehicles to proceed with the construction through reflective surfaces or lights, thus preventing vehicles from accidentally entering the construction area and causing unnecessary losses.
[0003] Currently, the equipment used for safety guidance at highway construction sites is mostly reflective guardrails. These guardrails enclose the construction area, and their outer surfaces have reflective stickers to guide oncoming vehicles to turn in time. However, in actual use, there are some functional shortcomings and room for improvement. For example, guardrails are generally made of metal, and depending on the construction requirements, some guardrails are fixed to the road surface. During a collision, the fixed guardrails are directly impacted, and they may break and fly out or penetrate the front of the car, causing significant damage and posing a greater potential safety risk. They also lack the function of absorbing energy and reducing injury upon impact.

[0010] As a further technical solution of this utility model, the front end of the inner support rib is connected to the front end of the front baffle, and the left and right ends of the front baffle and the inner support rib are flush.
[0011] As a further technical solution of this utility model, a side fixing plate is fixedly connected to the top of the inner side of the first pile body and the second pile body, and a plate frame is movably connected between one side of the two sets of side fixing plates. A warning sign is fixedly connected inside the plate frame, and an internal threaded pipe seat is fixedly connected to the side of the side fixing plate away from the plate frame. A hand-tightening bolt is inserted laterally inside the internal threaded pipe seat.
[0012] As a further technical solution of this utility model, the external thread of the hand-tightening bolt matches the internal thread of the internal threaded pipe seat, and the hand-tightening bolt passes through the internal threaded pipe seat and extends into the interior of the plate frame.

The corresponding angle can be adjusted according to the shape of the construction area. The six sets of first positioning bolt holes and second positioning bolt holes allow the relative angle of the two sets of guardrails to be flexibly adjusted. Then, the positioning long bolt is driven in. The positioning long bolt passes through the first positioning bolt hole and the second positioning bolt hole, and the angle is fixed, thus realizing the function of easy connection and reinforcement.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, the front bumper 5 is directly impacted. The arc-shaped front bumper 5 is deformed and extended inward under the impact. The hexagonal metal energy-absorbing box 4 collapses and forms wrinkles, absorbing part of the impact energy. The inner support ridge 7 can increase the structural strength of the front bumper 5 and reduce its probability of breakage.
[0031] Side fixing plates 9 are fixedly connected to the top of the inner side of the first pile body 1 and the second pile body 8. A plate frame 12 is movably connected between one side of the two sets of side fixing plates 9. A warning sign 13 is fixedly connected inside the plate frame 12. An internal threaded pipe seat 10 is fixedly connected to the side of the side fixing plate 9 away from the plate frame 12.

The external thread of the hand-tightening bolt 11 matches the internal thread of the internal threaded pipe seat 10. The hand-tightening bolt 11 passes through the internal threaded pipe seat 10 and extends into the inside of the plate frame 12, which facilitates flipping and switching the warning sign.
[0032] Specifically, such as Figure 1 and Figure 3 As shown, loosen the hand-tightening bolt 11, and the hand-tightening bolt 11 moves outward along the internal threaded pipe seat 10. As the hand-tightening bolt 11 disengages from the plate frame 12, the plate frame 12 and the warning sign 13 can be flipped together. After flipping, tighten the hand-tightening bolt 11 again, and the hand-tightening bolt 11 will be inserted into the plate frame 12, thus defining its position.
[0033] Three sets of first couplings 14 are fixedly connected to the right side of the first pile body 1, and two sets of second couplings 15 are fixedly connected to the left side of the second pile body 8.

[0034] Specifically, such as Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, a connecting bolt 16 is inserted along the first connecting bolt hole 18. The connecting bolt 16 passes through the first connecting bolt hole 18 and the second connecting bolt hole 20, thus connecting the two sets of guardrails into one unit. The corresponding angle can be adjusted according to the shape of the construction area. The six sets of first positioning bolt holes 19 and second positioning bolt holes 21 allow for flexible adjustment of the relative angle of the two sets of guardrails. Then, a positioning bolt 17 is driven in. The positioning bolt 17 passes through the first positioning bolt hole 19 and the second positioning bolt hole 21, thus completing the angle fixation.
[0035] Working principle: When this utility model is in use, firstly, the first pile body 1 and the second pile body 8 are fixed on the road surface, providing physical support for the fixation of the horizontal guardrail 2 and the vertical guardrail 3. The front guardrail 5 faces outward, and the reflective sticker 6 on it can be brightly displayed under the headlights of oncoming vehicles, which can guide oncoming vehicles to drive in the correct direction. When the vehicle makes a wrong turn and crashes into the construction area, the front guardrail 5 is directly impacted. The arc-shaped front guardrail 5 is deformed and extended inward under the impact, and the hexagonal metal energy-absorbing box 4 collapses and forms wrinkles, absorbing part of the impact energy. The inner support ridge 7 can increase the structural strength of the front guardrail 5 and reduce its probability of breakage. Warning slogans are sprayed on the surface of warning sign 13. Different warning slogans are sprayed on the front and back of warning sign 13 to correspond to different usage scenarios. When it is necessary to switch the warning slogans according to the usage needs, first loosen the hand-tightening bolt 11. The hand-tightening bolt 11 moves outward along the internal thread pipe seat 10. As the hand-tightening bolt 11 disengages from the plate frame 12, the plate frame 12 and the warning sign 13 can be flipped together. After flipping, tighten the hand-tightening bolt 11 again. The hand-tightening bolt 11 is inserted into the plate frame 12, which can limit its position. When connecting two sets of guardrails, their corresponding first joint 14 and second joint 15 are aligned. First, the connecting bolt 16 is inserted along the first connecting bolt hole 18. The connecting bolt 16 passes through the first connecting bolt hole 18 and the second connecting bolt hole 20, and the two sets of guardrails are connected as one. The corresponding angle can be adjusted according to the shape of the construction area. The six sets of first positioning bolt holes 19 and second positioning bolt holes 21 allow for flexible adjustment of the relative angle of the two sets of guardrails. Then, the positioning bolt 17 is driven in. The positioning bolt 17 passes through the first positioning bolt hole 19 and the second positioning bolt hole 21, and the angle is fixed.
