[0002] During highway construction, it is necessary to ensure that there is no vehicle interference on the construction section to ensure the construction quality and construction environment. The common practice is to place roadblocks and warning signs. Roadblocks are mostly protective crash barriers or conical warning cylinders, and warning signs are vertical signs with a certain height. There are white or yellow warning words on the signs to prevent accidental collisions and reduce losses.

[0003] Most of the road construction safety warning signs in the existing technology are single-sided and can only serve as a warning to pedestrians in one direction. The warning range is small, and in order to serve as a warning at night, the surface of the warning signs is mostly covered with reflective film. However, during transportation and storage, the surface of the warning signs is easily scratched and damaged due to the lack of isolation and protection measures, which affects the clarity of the characters and the reflective effect. Utility Model Content

[0004] The utility model aims to provide a road construction safety warning sign, which expands the warning range of the warning sign and can provide safety warnings to pedestrians in three directions. The warning sign can be flipped and folded, thereby protecting the surface of the warning sign to prevent scratches and other damages that may affect the clarity of the characters and the reflective effect. After folding, the warning sign has a small volume and is easy to store.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A road construction safety warning sign, comprising a warning plate and a sleeve, wherein the inner wall of the sleeve is slidably connected with a sliding rod, the sliding rod is fixedly connected with a connecting plate through a connecting rod, the bottom of the sliding rod is symmetrically fixedly connected with a sliding block, the middle of the sliding block is elastically connected with a spring rod, two sliding grooves for the sliding block to slide are provided on both sides of the inner wall of the sleeve, positioning holes for the spring rod to be embedded and connected are symmetrically penetrated on both sides of the sleeve, and a sliding groove for the connecting rod to be embedded and slid is symmetrically penetrated on both sides of the sleeve and on one side adjacent to the positioning hole;

[0007] The outer wall of the connecting plate is fixedly connected with a bent pipe in an array, one end of the bent pipe is fixedly connected with a transfer rod located above the connecting plate, both sides of the transfer rod are rotatably connected with rotating circles, and the warning plate is fixedly connected to the rotating circle.

[0008] The top of the sliding rod is fixedly connected with a baffle.

[0009] Both sides of the warning plate are provided with through-type clamping grooves for the bent pipe to be inserted and engaged.

[0010] A snap ring is rotatably connected on one side of the warning plate and located at one side of the snap slot.

[0011] One end of the clamping ring is slidably connected to a fixing rod, and the warning plate is slidably connected to the fixing rod.

[0012] The bottom of the sleeve is fixedly connected with a telescopic rod in an array manner.

[0013] The inner wall of the telescopic rod 1 is slidably connected with the telescopic rod 2, and one end of the telescopic rod 2 is fixedly connected with the tripod.

[0014] The technical effects achieved by the utility model are as follows: the warning range of the warning sign is expanded, and safety warnings can be given to pedestrians in three directions; the warning sign can be flipped and folded, thereby protecting the surface of the warning sign to prevent scratches that affect the clarity of the characters and the reflective effect; and after folding, the warning sign has a small volume and is easy to store.
