DETAILED DESCRIPTION
[0022] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0023] like Figure 1-Figure 4As shown, the road construction warning sign provided by the present embodiment includes a bottom fixing seat 1, a supporting partition 11 is fixedly connected to the inner wall of the bottom fixing seat 1, the supporting partition 11 is located at the central axis position of the bottom fixing seat 1, and two cavities are formed between the supporting partition 11 and the bottom fixing seat 1, and two supporting columns 2 are threadedly connected to the upper surface of the supporting partition 11, and the two supporting columns 2 are symmetrically distributed about the central axis of the supporting partition 11, and a connecting piece 3 is inserted at one end of the supporting column 2 away from the supporting partition 11, and a connecting protrusion 31 is fixedly connected to the outer wall of the connecting piece 3, and a warning plate 4 is fixedly connected to the side of the two connecting protrusions 31 away from the connecting piece 3, and the upper and lower sides of the warning plate 4 are fixedly connected to side plates 41, and a sliding groove 411 is provided on the side where the two side plates 41 are close to each other, and an automatic winding drum 42 is connected to the side where the two side plates 41 are close to each other, and a flexible sign body 43 is provided on the automatic winding drum 42, and a sliding plate 44 is fixedly connected to the other end of the flexible sign body 43, and the sliding plate The two ends of 44 are slidably connected with the two slide grooves 411, and a second bolt 45 is inserted on one side of the side plate 41. The second bolt 45 is located at a side direction position of the side plate 41 away from the automatic winding drum 42. One end of the second bolt 45 penetrates the side plate 41 and is threadedly connected to the warning plate 4. The outer walls of the two second bolts 45 are both clamped with the sliding plate 44. By placing heavier objects such as suitable counterweights, sand and stones in the cavity formed between the bottom fixing seat 1 and the supporting partition 11, the bottom of the road construction warning sign is stabilized, making the road construction warning sign more stable. The warning plate 4, side plate 41, automatic winding drum 42 and sliding plate 44 are used to fix and support the flexible sign body 43 and protect the flexible sign body 43, reduce the wind force on the flexible sign body 43, and make the fixation of the flexible sign body 43 more stable. When not in use, the flexible sign body 43 is stored by the automatic winding drum 42, and the flexible sign body 43 is effectively protected.
[0024] Secondly, if Figure 1 , Figure 2 as well as Figure 3As shown, two counterweights 12 are placed in the two cavities, and the two counterweights 12 are adapted to the cavities. A fixed handle 121 is fixedly connected to the upper surface of the counterweight 12, and the fixed handle 121 is located at the center of the counterweight 12. A connecting groove is opened on the lower surface of the counterweight 12, and the connecting groove is adapted to the size of the fixed handle 121. The connecting groove and the fixed handle 121 are symmetrically distributed with respect to the counterweight 12. Two handle connectors 13 are fixedly connected to the outer wall of the bottom fixing seat 1, and the two handle connectors 13 are symmetrically distributed with respect to the bottom fixing seat 1. A movable handle 14 is rotatably connected to the hand connecting piece 13. The center of gravity of the road construction warning sign is lowered by the gravity of the counterweight block 12 itself, making the road construction warning sign more stable. The fixed handle 121 is used to facilitate the taking and placing of the counterweight block 12. When the single-layer counterweight block 12 is insufficiently weighted, another counterweight block 12 can be added to the counterweight block 12. At this time, the connecting groove of the upper counterweight block 12 is connected to the fixed handle 121 of the lower counterweight block 12 correspondingly, which can increase the bottom counterweight of the road construction warning sign. The movable handle 14 is used to facilitate the movement of the bottom fixed seat 1.
[0025] Further, such as Figure 1 , Figure 2 as well as Figure 3 As shown, a reinforcement 21 is sleeved on the outer wall of the support column 2 and a fixing nut 22 is threadedly connected. The lower surface of the reinforcement 21 contacts the upper surface of the support partition 11, and the upper surface of the reinforcement 21 contacts the lower surface of the fixing nut 22. The diameter of the lower surface of the reinforcement 21 is larger than the diameter of the upper surface of the reinforcement 21. The reinforcement 21 and the fixing nut 22 are used to increase the connection firmness between the support column 2 and the support partition 11, making the support column 2 more stable.
[0026] Furthermore, if Figure 1 , Figure 2 as well as Figure 3As shown, three cylinders 32 and three threaded cylinders 33 are connected on the outer wall of the connecting member 3, and the three cylinders 32 correspond to the three threaded cylinders 33 one by one, and the three cylinders 32 and the three threaded cylinders 33 are symmetrically distributed about the connecting member 3, and the three connecting protrusions 31 are equidistant in sequence. A first bolt 34 is threadedly connected to the inner wall of the threaded cylinder 33, and the bolt head of the other end of the first bolt 34 contacts the corresponding cylinder 32, and the threaded cylinder 33 and the connecting protrusion 31 are vertically distributed. A plurality of connecting holes 23 are opened on the outer wall of the support column 2, and the plurality of connecting holes 23 are equidistant in sequence. The distance between two adjacent connecting holes 23 is equal to the distance between two adjacent threaded cylinders 33, and the first bolt 34 is plugged into the corresponding connecting hole 23. Through the connection and cooperation among the cylinder 32, the threaded cylinder 33, the first bolt 34 and the connecting hole 23, the connecting member 3 is firmly connected to the supporting column 2, which facilitates the installation and disassembly of the road construction warning sign, increases the stability of the road construction warning sign, and increases the convenience of the road construction warning sign.
[0027] like Figure 1-Figure 4 As shown, the principle of the road construction warning sign provided in this embodiment is as follows: when using this road construction warning sign, a counterweight block 12 is placed in the cavity formed between the bottom fixing seat 1 and the supporting partition 11 to stabilize the bottom of the road construction warning sign, so that the road construction warning sign is erected more stably, and the center of gravity of the road construction warning sign is lowered by the gravity of the counterweight block 12 itself, making the road construction warning sign more stable. When the single-layer counterweight block 12 is not heavy enough, another counterweight block 12 can be added on the counterweight block 12. The connecting groove of the upper counterweight block 12 is connected correspondingly to the fixed handle 121 of the lower counterweight block 12, which can increase the bottom counterweight of the road construction warning sign. The flexible sign body 43 is fixedly supported and protected by the warning plate 4, the side plate 41, the automatic winding drum 42 and the sliding plate 44, reducing the wind force on the flexible sign body 43 and making the fixation of the flexible sign body 43 more stable. When not in use, the flexible sign body 43 can be stored by the automatic winding drum 42 to effectively protect the flexible sign body 43.
