Description

Technical Field

[0001] The present application relates to the field of road traffic technology, and in particular to a rotatable cantilever rod structure. Background Art

[0002] Traffic lights are a category of traffic safety products. They are an important tool to strengthen road traffic management, reduce the occurrence of traffic accidents, improve road use efficiency, and improve traffic conditions. They are suitable for intersections such as crosses and T-shaped intersections. They are controlled by road traffic signal controllers to guide vehicles and pedestrians to pass safely and orderly. Traffic lights are a type of signal light composed of three colors of red, yellow, and green. When the green light is on, vehicles are allowed to pass. When the yellow light is on, vehicles that have crossed the stop line can continue to pass; when the red light is on, vehicles are prohibited from passing. The structure of traditional traffic lights is extremely simple. Most of them are to install the red, yellow, and green lamp bodies on a lamp frame, and then fix the lamp frame on a column or other fixing device.

[0003] In daily traffic, traffic lights have the function of directing traffic and can reduce the workload of traffic police. However, existing traffic lights still have shortcomings. The existing traffic lights have relatively single functions. In addition to indicating travel orders, they have no other functions. It is difficult to adapt to people's current needs for obtaining complex road conditions information. In strong sunlight, due to the glare of the external light, it is impossible to correctly identify the signal prompts of traffic lights. Moreover, traffic lights are mostly installed on electric poles at intersections. Because the installed traffic lights are too high, they need to be repaired with the help of ladders and other tools, which is inconvenient and will affect traffic and pedestrians on the road.

[0004] A Chinese patent with publication number "CN219831966U" discloses a traffic signal device that is easy to maintain, including a bracket and a traffic light. The bracket includes a fixed rod and a movable rod. A groove is provided on one side of the fixed rod. The movable rod is embedded in the groove and hinged with the fixed rod. The traffic light is installed on the movable rod. A traction rope is fixedly provided on one side of the movable rod. An electric winding assembly for winding the traction rope is fixedly provided on the side of the fixed rod away from the groove. During maintenance, the staff only needs to start the electric winding assembly to slowly loosen the wire rope, and the movable rod and the fixed rod will rotate relative to each other. When the movable rod rotates 90° clockwise, it will contact the ground, which greatly facilitates the staff to carry out maintenance.

[0005] Although the above invention solves the problems in the background technology to a certain extent, there are still some problems:

[0006] 1. When the device is in use, although it can lower the traffic lights and repair them, it will block the road surface in some narrow sections of the road, easily causing traffic jams and affecting people's normal travel;

[0007] 2. Although the device can be rotated to a certain angle when maintenance is required, there is no limit device at the rotation point, and there is a risk of damage to the device due to excessive rotation angle. Utility Model Content
