Description

Technical Field

[0001] The utility model relates to the technical field of construction warnings, in particular to a road and bridge construction warning sign. Background Art

[0002] Road and bridge construction refers to the construction, reconstruction, expansion, or repair of roads and bridges. Road and bridge construction warning signs are a crucial component of traffic safety during this process. They are primarily used in road and bridge construction areas to alert drivers and pedestrians to safety precautions. These signs are typically made of reflective material to ensure visibility at night or in low-light conditions.

[0003] Traditional road and bridge construction warning signs are not easy to adjust the length of the warning curtain when in use, which results in car drivers being unable to judge the area occupied by the road construction area based on the length of the warning curtain. The warning area is small and not eye-catching enough.

[0004] Therefore, those skilled in the art provide a road and bridge construction warning sign to solve the problems raised in the above background technology. Utility Model Content

The device consists of a first support frame and a second support frame. A storage cylinder is set at the front end of the first support frame, and a warning reflective curtain is set on a rotating shaft. The warning reflective curtain inside the storage cylinder is connected to the traction rod at the front end of the second support frame. When the warning sign is unfolded, it can be towed according to the construction area to achieve the purpose of adjusting the length. It can help drivers judge the area of ​​the road occupied by the construction through the warning sign, which can be more eye-catching.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A road and bridge construction warning sign comprises a first support frame and a second support frame, wherein a storage cylinder is fixedly provided on the front end surface of the first support frame, a rotating shaft is rotatably provided inside the storage cylinder, a reflective warning curtain is wound on the rotating shaft, a rotating disk is rotatably provided on the top of the storage cylinder, the middle part of the bottom end of the rotating disk is fixedly connected to the rotating shaft, a control handle is fixedly provided on one side of the top of the rotating disk, a traction rod is fixedly provided on the front end of one side of the second support frame, and the traction rod is fixedly connected to the reflective warning curtain.

[0008] Through the above technical solution, the reflective warning curtain of the warning sign is set inside the storage tube. When in use, the first support frame and the second support frame are directly unfolded according to the construction area to achieve the warning effect.

[0014] Furthermore, a latch is provided in the middle of the first crossbeam, a latch hole is provided in the middle of the second crossbeam, and the latch passes through the latch hole;

[0015] With the above technical solution, when the device is stored for carrying, the latch is pulled out and passed through the first crossbeam and the second crossbeam, thereby achieving position limiting and preventing the support frame from spreading out during carrying.

[0016] Furthermore, a hollow groove is provided on one side of the second support frame and the second crossbeam;

[0017] Through the above technical solution, the hollow groove is opened to reduce the top weight of the entire warning sign, making it easier to carry and lowering the center of gravity.
