[0002] Safety warning roadblocks are generally used to alert passing vehicles during road repairs to prevent them from entering the repair area and causing accidents.

[0003] However, the existing safety warning roadblocks may be blown down when the wind blows, or the warning signs on the roadblocks cannot be seen clearly at night, which may lead to safety accidents. The safety warning roadblocks optimized for the above situation are often not convenient to store. For example, a safety warning roadblock disclosed in Chinese patent announcement number "CN216892125U" has a structural design that makes it difficult for the safety warning roadblock to fall down when the wind blows, but its structure cannot be folded, and since the safety warning roadblock is not disposable, it will be recycled after use. At this time, the device will occupy a relatively large amount of space due to its non-foldable structure, which reduces the number of single shipments and increases the transportation cost. Based on this, the present application proposes a multifunctional safety warning roadblock for highway engineering. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-7 A multifunctional safety warning roadblock for highway engineering includes a base 18, a storage slot 24, and a counterweight slot 17. Two counterweight blocks 23 are placed in the counterweight slot 17. A taking slot 19 is provided on the base 18. A storage slot 24 is provided in the center of the two counterweight blocks 23. A first telescopic plate 5 is rotatably connected to the side wall of the tail of the storage slot 24. A telescopic slot 6 is provided at the top of the first telescopic plate 5. A screw slot 22 is provided inside the first telescopic plate 5. A second telescopic plate 4 is slidably connected inside the screw slot 22. A warning sign 1 is threadedly connected to the top of the second telescopic plate 4. A screw 2 is threadedly connected to the side wall of the second telescopic plate 4 near the top. A screw rod 7 is threadedly connected to the position near the top of the retractable plate 5, a positioning member 8 is fixedly connected below the screw rod 7, a rotating shaft 9 is rotatably connected to the side wall of the positioning member 8, a small telescopic rod 10 is fixedly connected to the rotating shaft 9, a large telescopic rod 12 is slidably connected to the small telescopic rod 10, a support shaft 11 is fixedly connected to the large telescopic rod 12, a support member 13 is rotatably connected to the support shaft 11, a support limit guide rail 14 is slidably connected below the support member 13, a slide groove 15 is provided on the support limit guide rail 14, a positioning groove 16 is provided at one end of the slide groove 15 near the first telescopic plate 5, and a telescopic plate rotating shaft 20 is rotatably connected to the side wall of the tail end of the storage groove 24. It should be noted that when the first telescopic plate 5 is stored in the storage groove 24, it can be taken out using the taking groove 19.

[0025] The support member 13 is placed in the positioning groove 16, a warning sign placement groove 21 is provided inside the base 18, and the telescopic plate shaft 20 is fixedly connected to the lower end of the first telescopic plate 5. It should be noted that the two counterweights 23 have the same specifications.

[0026] The material of the counterweight block 23 is gray cast iron. It should be noted that all parts except the counterweight block 23 are plastic, and the type of all plastics in this device is polyethylene plastic.

[0027] When using the device, first place the base 18 on the ground, then put your fingers into the taking groove 19 to pick out the first telescopic plate 5, then stand it up, and then slide the support member 13 into the positioning groove 16. Because the groove distance in the large telescopic rod 12 is relatively limited, when the support member 13 slides into the positioning groove 16, the small telescopic rod 10 just reaches the inner bottom of the second telescopic plate. Since the large telescopic rod 12 is connected to the support member 13, the space for the first telescopic plate 5 to move downward will be supported by the small telescopic rod 10 and the large telescopic rod 12, thereby fixing the first telescopic plate 5, and then the second telescopic plate 4 is pulled out of the screw groove 22 through the telescopic groove 6. At this time, the screw 2 will also open along the side of the screw groove 22. The second telescopic plate will slide out of the gap designed, and when it reaches a suitable height, the screw 7 is tightened. At this time, the bottom of the screw 7 will be pressed against the side wall of the second telescopic plate 4 to fix its height. Then the warning sign 1 is taken out from the inside of the warning sign placement groove 21 and the protruding part of the warning sign 1 is placed in the fixing groove 3, and then the screw 2 is tightened. At this time, the warning sign 1 is fixed, and the counterweight block 23 is placed in the counterweight groove 17 in advance to lower the center of gravity of the entire device, thereby preventing it from tipping over. The warning sign 1 is written with a warning slogan made of fluorescent material, so that pedestrians can see the device clearly at night, and because the fluorescent material emits light as its own characteristic, it is more stable and environmentally friendly than battery-powered lights, and the cost is also lower.

[0028] When the device needs to be folded up, the screw 2 is loosened, and the warning sign 1 can be taken out of the fixing groove 3 and placed in the warning sign placement groove 21. The warning sign placement groove 21 is paved with a rubber material for anti-slip, and the warning sign 1 is placed and slides out of it, and then the support member 13 is placed in the slide groove 15, and the support member 13 can slide in the slide groove 15. At this time, the screw rod 7 is loosened again, and the second telescopic plate 4 will slide into the first telescopic plate 5 along the screw groove 22. The screw groove 22 has a portion extending outward, and the screw 2 can slide into the second telescopic plate 5 along it. When the second telescopic plate 4 slides into the first telescopic plate 5, the first telescopic plate 5 is pressed into the receiving groove 24, and all the parts can be stored in the base 18. Because there is a certain space between the side of the first telescopic plate 5 and the bottom of the receiving groove 24, it can be used to store the screw 7 without lifting the first telescopic plate 5. Because the support member 13 can slide along the slide groove 15, the support member 13 will be pushed forward when the first telescopic plate 5 is pressed down, so the support member 13 will not affect the storage of the first telescopic plate 5.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
