Abstract
Description
Technical Field
[0001] This utility model relates to the field of road safety facilities technology, and in particular to a road warning sign. Background Technology
[0002] In the road traffic safety management system, warning signs serve as a crucial information transmission medium, bearing the heavy responsibility of accurately conveying important information such as road conditions, traffic rules, and hazard warnings to passing vehicles and pedestrians. Like silent traffic controllers, they play an irreplaceable role in guiding traffic order and preventing traffic accidents.
[0003] Traditional warning signs are mostly designed with fixed sizes and are usually placed directly where warnings are needed. However, each location is different, and the requirements for warning signs are also different. For example, on main urban roads, due to the high traffic volume and speed, large warning signs are required to ensure that drivers can clearly see the information from a distance. On narrow rural roads or construction sections, oversized signs will not only affect traffic but may also pose safety hazards. In these cases, smaller and more flexible warning signs are needed. At the same time, fixed-size warning signs often occupy a lot of storage space when not in use, which brings great inconvenience to management and use, whether for loading on transport vehicles or storing in warehouses.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0030] Reference Figures 1-5 A road warning sign includes a frame 1, with symmetrical through slots 11 on the side walls of the frame 1, a warning plate 2 inside the frame 1, and slide rails matching an extension plate 3 on the side walls of the frame 1. The interior of the warning plate 2 is hollow, and slide rails matching the extension plate 3 are provided on the inner side walls of the warning plate 2. The top surface of the warning plate 2 is open, and a handle is provided on the top of the extension plate 3 to facilitate the removal of the extension plate 3 from the warning plate 2 by staff.
[0031] A road warning sign also includes a support assembly and a limiting assembly. The limiting assembly is used to restrict the position of the extension plate 3. The limiting assembly includes a sleeve rod 31, a sliding rod 32, a spring 33, a locking block 34, and a locking groove 35. The sleeve rod 31 is symmetrically fixedly connected to the side wall of the extension plate 3. The sliding rod 32 is slidably connected to the inside of the sleeve rod 31. One end of the spring 33 is fixed to the inner wall of the sleeve rod 31, and the other end of the spring 33 is fixedly connected to the bottom end of the sliding rod 32. The locking block 34 is fixedly connected to the end of the sliding rod 32 away from the spring 33. The top surface of the locking block 34 is arc-shaped, and the slots 35 are symmetrically opened on the side wall of the frame 1. The locking block 34 and the slots 35 are inserted into each other. When the expansion plate 3 slides to the appropriate position, the arc-shaped structure and the slots 35 on the side wall of the frame 1 form a natural guide. Without complicated operation, the locking block 34 can automatically slide into the slots 35 along the arc-shaped surface under the elastic force of the spring 33, achieving precise locking. At the same time, it can also effectively prevent the locking block 34 and the edge of the slot 35 from getting stuck, ensuring that the expansion plate 3 is quickly and smoothly fixed in place.
[0032] The support assembly is used to stably support the frame 1. The support assembly includes a rotating shaft 21, a rotating plate 22, a storage slot 221, a rotating rod 23, a connecting plate 24, a mounting block 25, a retaining plate 26, and a placement slot 27. The rotating shaft 21 is rotatably connected to the inner wall of the through slot 11. The rotating plate 22 is fixedly connected to the rotating shaft 21, and the rotating plate 22 has a storage slot 221. The rotating rod 23 is fixedly connected to the inner wall of the storage slot 221. One end of the connecting plate 24 is hinged to the rotating rod 23. The mounting block 25 is hinged to the other end of the connecting plate 24. The retaining plate 26 is fixedly connected to the end of the mounting block 25 away from the connecting plate 24. The placement slot 27 is located on the side wall of the warning plate 2. The top of the 7th section is connected to the through groove 11. The placement groove 27 is inserted into the card plate 26. The two sides of the placement groove 27 are provided with cavities that match the card plate 26. By hingedly rotating the connecting plate 24 around the rotating rod 23, the position of the mounting block 25 and the card plate 26 can be flexibly adjusted so that the card plate 26 can be accurately inserted into the placement groove 27 on the side wall of the warning board 2 and fit tightly with the cavities on both sides, thereby forming a stable triangular support structure. This structure can not only effectively disperse the external force on the sign, but also ensure that the sign remains upright under strong winds and vehicle airflow impacts. It can also flexibly adjust the support angle according to different terrains and usage scenarios, greatly improving the environmental adaptability and practicality of the warning sign.
[0033] The functional principle of this utility model can be explained through the following operation methods:
[0034] First, when using this road warning sign, if it is necessary to expand the display area of the equipment, the operator can pull the extension plate 3 upwards. The extension plate 3 can be smoothly slid by using the inner wall slide rail of the frame 1 and the warning plate 2. During this process, the inner slide rod 32 of the sleeve rod 31 compresses the spring 33, which drives the locking block 34 to move. When the extension plate 3 is in place, the spring 33 restores its elasticity and pushes the locking block 34 into the side wall slot 35 of the frame 1, thereby limiting and fixing the extension plate 3.
[0035] To reduce the size, press the latch 34 to cause the bottom slide bar 32 to compress the spring 33, causing the latch 34 to disengage from the slot 35, and the operator can then store the extension plate 3 inside the frame.
[0036] When placing the sign, first rotate the rotating plate 22 connected to the rotating shaft 21 on the inner wall of the through groove 11 of the frame 1 to a suitable angle, then rotate the connecting plate 24 around the rotating rod 23 in the storage groove 221 to adjust the position of the mounting block 25 and the clamping plate 26, insert the clamping plate 26 into the placement groove 27 on the side wall of the warning plate 2 and fix it with the cavity on both sides, so that the rotating plate 22 stably supports the frame 1.
[0037] After use, pull out the card plate 26, rotate the connecting plate 24 and the rotating plate 22 in the opposite direction, and store them inside the through slot 11 and the placement slot 27 for easy storage and transportation.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
