Description

Technical Field

[0001] The utility model relates to the technical field of warning signs, in particular to a highway construction warning sign. Background Art

[0002] As the name suggests, a warning sign is a sign that can provide warnings to people. When the highway is under construction, in order to avoid traffic accidents among passing vehicles, a high-altitude highway construction warning sign is usually set up at the entrance of the construction section to remind passing vehicles that the road ahead is under construction, effectively avoiding the occurrence of safety accidents. However, in actual use, the highway construction warning sign is inconvenient to disassemble and replace, which reduces the usability and practicality of the warning sign. In addition, the stability of the highway construction warning sign needs to be improved when in use. For this reason, we provide a highway construction warning sign. Utility Model Content

Detailed implementation mode

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0020] Embodiment 1

[0021] Please refer to Figure 1-3 , a warning sign for highway construction, including a base 1. On the top surface of the base 1, there are two vertically arranged plates 2 that are symmetrically arranged left and right, and the tops of the two vertically arranged plates 2 are jointly connected with a mounting plate 3. The width of the vertically arranged plate 2 is the same as the width of the mounting plate 3 (not shown in the figure). The base 1 and the mounting plate 3 are fixed to the vertically arranged plate 2 by welding. In the middle of the front end surface of the mounting plate 3, a warning sign body 4 is attached. A fixing structure is provided on the warning sign body 4, and a group of limiting plates 5 are fixedly arranged on the rear end wall of the warning sign body 4, and the other ends of the group of limiting plates 5 are all movably penetrated and connected with the front end surface of the mounting plate 3. A limiting groove 6 adapted to the limiting plate 5 is opened on the mounting plate 3 (the limiting plate 5 and the limiting groove 6 are slidably connected). Through the mutual cooperation between the limiting plate 5 and the limiting groove 6, the warning sign body 4 can be pre-placed on the mounting plate 3, and the fixing position of the warning sign body 4 can be quickly determined. In the middle of the front end surface of the base 1, a rectangular water bucket 7 is slidably penetrated. A slot adapted to the rectangular water bucket 7 is opened on the base 1 (not shown in the figure), and the rectangular water bucket 7 can be pulled out from the base 1.

[0022] Please refer to Figure 1-3 , the fixing structure includes a bearing 8. The bearing 8 is fixedly penetrated and connected to the center of the rear end surface of the mounting plate 3, and a lead screw 9 is rotatably connected inside the bearing 8. A central plate 10 is movably sleeved on the outer surface of the lead screw 9, and a screw hole adapted to the lead screw 9 is opened on the central plate 10 (not shown in the figure). On the left and right ends of the central plate 10, connecting plates 11 with a U-shaped side surface are fixedly arranged, and on the upper and lower ends of the front side of the connecting plate 11, fixing vertical plates 12 are fixedly arranged, and the four fixing vertical plates 12 are respectively closely attached to the four corners of the front end surface of the warning sign body 4. A rotating handle is fixedly connected to the center of the rear end of the lead screw 9. Through the setting of the fixing structure, the warning sign body 4 can be further limited and fixed, improving its stability on the mounting plate 3. By moving the four fixing vertical plates 12 away from the warning sign body 4, it can be disassembled and replaced, improving the use efficiency of the device.

[0023] Please refer to Figure 2The upper and lower surfaces of the connecting plate 11 are both provided with sliding grooves 13, and a slider 14 adapted thereto is slidably connected in the sliding grooves 13. The two sliders 14 are respectively connected to the upper and lower surfaces of the warning sign body 4, and the slider 14 is fixedly connected to the warning sign body 4. The sliding connection between the sliding grooves 13 and the sliders 14 is beneficial to improving the stability of the connecting plate 11 when it moves back and forth. When the slider 14 moves to fit the side of the sliding groove 13 away from the connecting plate 11, the fixed vertical plate 12 can be completely separated from the warning sign body 4, and the space between the fixed vertical plate 12 and the mounting plate 3 is sufficient to pull the warning sign body out of the mounting plate 3. There are two limit plates 5 in a group, and they are symmetrically distributed up and down.

[0024] See also Figure 1 The length of the limiting plate 5 is the same as that of the warning sign body 4 , the right end of the limiting groove 6 is flush with the right end of the mounting plate 3 , and the warning sign body 4 can be moved away from the mounting plate 3 .

[0025] See also Figure 1 and Figure 4 An externally threaded tube 15 is fixedly arranged on the middle surface of the front end of the rectangular water bucket 7, and a sealing cover 16 is threadedly sleeved on the externally threaded tube 15. Both left and right sides of the sealing cover 16 are provided with handles 17 fixedly connected to the rectangular water bucket 7. By rotating the sealing cover 16 in the opposite direction, the rectangular water bucket 7 can be opened, and water can be poured into the rectangular water bucket 7 or the water in the rectangular water bucket 7 can be poured out through the externally threaded tube 15. When there is water in the rectangular water bucket 7 and it is located on the base 1, the overall weight of the device can be increased, and the stability of the device can be improved. When the water in the rectangular water bucket 7 is poured out, the overall weight of the device can be reduced, thereby facilitating the transportation of the device.

[0026] Example 2

[0027] On the basis of embodiment 1, an anti-skid pad 18 is added. Figure 2 The rear end surface of the fixed vertical plate 12 is embedded with an anti-skid pad 18, and the anti-skid pad 18 is a rubber pad, and the other end of the anti-skid pad 18 is in contact with the warning sign body 4. The fixed vertical plate 12 is provided with an embedding groove (not shown) adapted to the anti-skid pad 18. By providing the anti-skid pad 18, the friction performance of the rear end wall of the fixed vertical plate 12 can be enhanced, thereby improving its fixing effect on the warning sign body 4, and further improving the use effect of the fixing structure.
