[0002] During road construction, in order to enhance on-site construction safety, traffic safety, and personal safety, it is necessary to close off and protect the construction section to prevent external vehicles from entering and to ensure that construction materials do not enter the road surface. The existing closure and protection methods mainly involve setting up barriers or warning signs to block the road, thereby making it easier for pedestrians to notice the road construction and avoid the construction section.

[0003] However, existing warning signs often use a one-piece metal frame, which is heavy and bulky, making it inconvenient to move to the target location. Utility Model Content

[0004] The main purpose of this application is to provide a warning device for road construction, which aims to solve the problem that existing warning signs are inconvenient to move.

[0005] To achieve the above objectives, this application provides a road construction warning device, which includes a mounting plate, a rotating rod, multiple pulleys, a tie rod, and a fixing assembly. The mounting plate has a top edge and a bottom edge opposite to each other in a first direction, the first direction being the same as the width direction of the mounting plate. The rotating rod is rotatably connected to one side of the mounting plate, with the connection area located at the top edge. The rotating rod has a degree of freedom to rotate about a second direction, the second direction being the same as the length direction of the mounting plate. The side of the rotating rod facing away from the mounting plate has a groove. Multiple pulleys are respectively connected to the mounting plate and the rotating rod, each pulley being located on the bottom edge facing away from the top edge, wherein each pulley is self-locking. The tie rod is disposed in the groove, with one end away from the top edge rotatably connected to the rotating rod. The tie rod has a degree of freedom to rotate about the second direction. The fixing assembly is disposed on the mounting plate to fix the warning sign to the side of the mounting plate facing away from the rotating rod.

[0006] Optionally, the warning device further includes two positioning plates and a first fixed shaft. The two positioning plates are arranged opposite each other in the second direction on the side of the mounting plate facing the rotating rod, and the positioning plates are located at the top edge. The first fixed shaft is fixed between the two positioning plates and its axial direction is the same as that in the second direction. The rotating rod is sleeved on the outer periphery of the first fixed shaft and is rotatably connected to the first fixed shaft.

[0007] Optionally, the warning device further includes a limiting plate, which is fixed to the end of the positioning plate away from the mounting plate and is inclined; wherein, when the rotating rod abuts against the limiting plate, the angle between the rotating rod and the mounting plate reaches its maximum.

[0008] Optionally, the rotating rod is interference-fitted with the first fixed shaft.

[0009] Optionally, the warning device further includes a second fixed shaft, which passes through the end of the pull rod away from the top edge and is connected to the rotating rod. The pull rod is rotatably connected to the second fixed shaft.

[0010] Optionally, the tie rod is interference-fitted with the second fixed shaft.

[0011] Optionally, the warning device further includes a handle connected to one end of the lever near the top edge and located outside the groove.

[0012] Optionally, the handle is rotatably connected to the lever and has a degree of freedom to rotate about the second direction.

[0013] Optionally, the length of the rotating rod is greater than the width of the mounting plate; there are three pulleys, two of which are arranged opposite each other in the second direction and are both connected to the mounting plate, and one pulley is fixed to the end of the rotating rod away from the top edge.

[0014] Optionally, the mounting plate is provided with a groove extending along the second direction on both the top and bottom edges, and two sliders are slidably engaged in each groove; the fixing assembly includes two pressure plates, a limiting rod, a limiting piece, and a spring. The two pressure plates are disposed opposite each other on the side of the mounting plate away from the rotating rod in the second direction. Both pressure plates extend along the first direction, and each end of the two pressure plates corresponds to a slider; the limiting rod passes through the slider and extends along a third direction, which is the same as the thickness direction of the mounting plate. The limiting rod has the freedom to slide along the third direction and is fixed to the corresponding pressure plate; the limiting piece is fixed to the end of the limiting rod away from the pressure plate; the spring is sleeved on the outer periphery of the limiting rod, and each end of the spring is connected to the limiting piece and the slider, respectively. The spring is in a contracted state.

[0015] This application provides a road construction warning device. In use, a warning sign can be fixed to a mounting plate using a fixing component. Then, rotating the rotating rod creates an angle between the rod and the mounting plate, bringing the mounting plate and the pulleys on the rod into contact with the ground. The warning sign is then supported on the ground by the mounting plate, and the pulleys self-lock to ensure the stability of the mounting plate. When the warning device needs to be moved, simply rotate the pull rod out of the groove and unlock the pulleys. The mounting plate can then be moved by the interaction of the pull rod and the pulleys. After moving, rotate the pull rod back into the groove and lock the pulleys. This allows a single person to easily move the warning device, making it more convenient to use. Attached Figure Description

[0026] refer to Figures 1-4 This application provides a road construction warning device, which may include a mounting plate 1, a rotating rod 2, multiple pulleys 3, a tie rod 4, and a fixing assembly 5. The mounting plate 1 has a top edge and a bottom edge that are opposite each other in a first direction, the first direction being the same as the width direction of the mounting plate 1. The rotating rod 2 is rotatably connected to one side of the mounting plate 1, with the connection area located at the top edge. The rotating rod 2 has a degree of freedom to rotate about a second direction, the second direction being the same as the length direction of the mounting plate 1. The side of the rotating rod 2 away from the mounting plate 1 has a groove 21. Multiple pulleys 3 are respectively connected to the mounting plate 1 and the rotating rod 2. Each pulley 3 is located on the bottom edge away from the top edge, and each pulley 3 is self-locking. The tie rod 4 is disposed in the groove 21, with one end away from the top edge rotatably connected to the rotating rod 2. The tie rod 4 has a degree of freedom to rotate about the second direction. The fixing assembly 5 is disposed on the mounting plate 1 to fix the warning sign to the side of the mounting plate 1 away from the rotating rod 2.

[0027] This application provides a road construction warning device. In use, the warning sign can be fixed to the mounting plate 1 using the fixing component 5. Then, the rotating rod 2 is rotated to maintain a certain angle between the rotating rod 2 and the mounting plate 1, bringing the mounting plate 1 and the pulleys 3 on the rotating rod 2 into contact with the ground. The warning sign is then supported on the ground by the mounting plate 1. At this time, the pulleys 3 self-lock to ensure the stability of the mounting plate 1. When the warning device needs to be moved, simply rotate the pull rod 4 out of the groove 21 and unlock each pulley 3. The mounting plate 1 can then be moved by the cooperation of the pull rod 4 and each pulley 3. After the movement is complete, rotate the pull rod 4 back into the groove 21 and lock each pulley 3. Thus, a single person can easily move the warning device, making it more convenient to use.

[0028] The mounting plate 1 is a plate-shaped component with length, width and thickness. The first direction is the X direction, which can be the same as the width direction of the mounting plate 1. The second direction is the Y direction, which can be the same as the length direction of the mounting plate 1. The third direction is the Z direction, which can be the same as the thickness direction of the mounting plate 1.

[0029] Specifically, such as Figure 2 As shown, when storing, the rotating rod 2 can be placed close to the mounting plate 1, and the pull rod 4 can be retracted into the groove 21. This can minimize the space occupied by the warning device and facilitate the storage and long-distance transportation of the warning device.

[0030] It should be understood that each pulley 3 can rotate around the first direction so that the pull rod 4 can pull the mounting plate 1 to move. Of course, each pulley 3 can also be a caster wheel, which makes it easier to turn.

[0031] Among them, "pulley 3 self-locking" means that pulley 3 cannot rotate, and "pulley 3 unlocking" means that pulley 3 can continue to rotate to move.

[0032] refer to Figure 2 In an exemplary embodiment, the warning device may further include two positioning plates 11 and a first fixed shaft 12. The two positioning plates 11 are disposed opposite each other in the second direction on the side of the mounting plate 1 facing the rotating rod 2, and the positioning plates 11 are located at the top edge. The first fixed shaft 12 is fixed between the two positioning plates 11 and its axial direction is the same as that in the second direction. The rotating rod 2 is sleeved on the outer periphery of the first fixed shaft 12 and is rotatably connected to the first fixed shaft 12.

[0033] Specifically, such as Figure 2As shown, the positioning plate 11 is located on the side of the mounting plate 1 facing the rotating rod 2. The positioning plate 11 is located at the top edge, which means that the positioning plate 11 is close to the top edge, or it can be understood as the positioning plate 11 being in contact with the top edge. The rotating rod 2 is sleeved on the outer periphery of the first fixed shaft 12 and is rotatably connected to the first fixed shaft 12. The axial direction of the first fixed shaft 12 is the same as the second direction, so that the rotating rod 2 can rotate around the second direction to form an angle between the rotating rod 2 and the mounting plate 1, so as to stably place the warning device.

[0034] refer to Figure 2 and Figure 3 In an exemplary embodiment, the warning device may further include a limiting plate 13, which is fixed to the end of the positioning plate 11 away from the mounting plate 1 and is inclined; wherein, when the rotating rod 2 abuts against the limiting plate 13, the angle between the rotating rod 2 and the mounting plate 1 reaches its maximum.

[0035] like Figure 3 As shown, at this time, the rotating rod 2 contacts the limiting plate 13 by rotating, so that the included angle between the rotating rod 2 and the mounting plate 1 reaches the maximum. In this way, when the rotating rod 2 and the mounting plate 1 provide support, the included angle between the rotating rod 2 and the mounting plate 1 cannot be further expanded, making the support more stable and ensuring good support even if the warning sign is heavy.

[0036] In an exemplary embodiment, the rotating rod 2 is interference-fitted with the first fixed shaft 12, so that the rotating rod 2 will not rotate on its own relative to the mounting plate 1 without the application of external force. Thus, when the warning device is transported over a long distance, the rotating rod 2 is in close contact with the mounting plate 1 and will not rotate, making it easier to transport the warning device.

[0037] refer to Figure 3 In an exemplary embodiment, the warning device may further include a second fixed shaft 22, which passes through the end of the pull rod 4 away from the top edge and is connected to the rotating rod 2. The pull rod 4 is rotatably connected to the second fixed shaft 22.

[0038] Specifically, one end of the pull rod 4 is sleeved on the outer periphery of the second fixed shaft 22 and rotatably connected to the second fixed shaft 22. The axial direction of the second fixed shaft 22 is the same as the second direction, so the pull rod 4 can rotate around the second direction to rotate out of or into the groove 21.

[0039] In an exemplary embodiment, the pull rod 4 is interference-fitted with the second fixed shaft 22, so that the pull rod 4 will not rotate on its own relative to the rotating rod 2 without the application of external force. Thus, when the warning device is transported over a long distance, the pull rod 4 will always be located in the groove 21 and will not rotate, making it easier to transport the warning device.

[0040] refer to Figure 2In an exemplary embodiment, the warning device may further include a handle 6, which is connected to one end of the lever 4 near the top edge and located outside the groove 21.

[0041] Specifically, by pulling the handle 6, force can be applied to the end of the lever 4 away from the second fixed shaft 22, making it easier to pull the lever 4 out or push it into the groove 21. At the same time, it is more convenient to grip the handle 6 to pull the lever 4 and further move the warning device.

[0042] refer to Figure 2 and Figure 3 In an exemplary embodiment, the handle 6 is rotatably connected to the lever 4 and has a degree of freedom to rotate about a second direction.

[0043] Specifically, when the handle 6 pulls the rod 4 out of the groove 21, the handle 6 can rotate around the second direction, which makes it easier to adjust the angle between the handle 6 and the rod 4 so that the handle 6 and the rod 4 are on the same axis, making it easier to move the rod 4 by pulling it with the handle 6.

[0044] refer to Figure 2 In an exemplary embodiment, the length of the rotating rod 2 is greater than the width of the mounting plate 1; there are three pulleys 3, two of which are arranged opposite each other in the second direction and are both connected to the mounting plate 1, and one pulley 3 is fixed to the end of the rotating rod 2 away from the top edge.

[0045] Specifically, when the length of the rotating rod 2 is greater than the width of the mounting plate 1, the pulley 3 connected to the rotating rod 2 is located on the side of the bottom edge away from the top edge. This ensures that the pulley 3 will not interfere with the mounting plate 1, so that the rotating rod 2 can be tightly attached to the mounting plate 1, which is convenient for the storage of the warning device and long-distance transportation.

[0046] refer to Figures 1-4 In an exemplary embodiment, the mounting plate 1 is provided with a groove 14 extending in a second direction on both its top and bottom edges. Two sliders 15 are slidably engaged in each groove 14. The fixing assembly 5 may include two pressure plates 51, a limiting rod 52, a limiting piece 53, and a spring 54. The two pressure plates 51 are disposed opposite each other in the second direction on the side of the mounting plate 1 away from the rotating rod 2. Both pressure plates 51 extend in a first direction, and their two ends correspond to a slider 15. The limiting rod 52 passes through the slider 15 and extends in a third direction, which is the same as the thickness direction of the mounting plate 1. The limiting rod 52 has the freedom to slide in the third direction and is fixed to the corresponding pressure plate 51. The limiting piece 53 is fixed to the end of the limiting rod 52 away from the pressure plate 51. The spring 54 is sleeved on the outer periphery of the limiting rod 52. The two ends of the spring 54 are connected to the limiting piece 53 and the slider 15, respectively. The spring 54 is in a contracted state.

[0047] Specifically, taking a pressure plate 51 as an example, a slider 15 is provided at each end of the pressure plate 51. The two sliders 15 are respectively slidably engaged with a slide groove 14. The slide groove 14 extends in the second direction, so the pressure plate 51 can slide in the second direction. At one end of the pressure plate 51, a limiting rod 52 extending in the third opposite direction is fixed. The limiting rod 52 passes through the corresponding slider 15 and can slide in the third direction, so the pressure plate 51 can move away from or towards the mounting plate 1 in the third direction. A limiting piece 53 is fixed at the end of the limiting rod 52 away from the pressure plate 51, and a spring 54 is sleeved on the outer periphery of the limiting rod 52. The two ends of the spring 54 are respectively connected to the limiting piece 53 and the slider 15. When the spring 54 is in a contracted state, the spring 54 will apply elastic force to the limiting piece 53, so that the limiting piece 53 pulls the limiting rod 52 and the pressure plate 51 to move, so that the pressure plate 51 is tightly attached to the mounting plate 1.

[0048] When installing a warning sign, the pressure plate 51 can be pulled along a third direction to insert the warning sign into the gap between the pressure plate 51 and the mounting plate 1. Then, the pressure plate 51 is released, and the pressure plate 51 is driven by the spring 54 to approach the mounting plate 1 and cooperate with the mounting plate 1 to clamp the warning sign. Both pressure plates 51 can be moved along a second direction, so that warning signs of different sizes can be fixed, making it more convenient to use.

[0049] Furthermore, a handle can be provided on the side of the pressure plate 51 away from the mounting plate 1, so as to drive the pressure plate 51 to move in the second or third direction by the handle.

[0050] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
