Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of municipal engineering, in particular to a road safety guardrail. Background Art
[0002] In municipal engineering, when the road needs to be repaired, or when a subway is opened or a cable is repaired, a road safety guardrail will be used to warn pedestrians and vehicles passing by to pay attention to safety. There are at least the following disadvantages in the use of existing safety guardrails: 1. All existing safety guardrails are made of metal or hard plastic. Although the strength of the guardrail is increased, impact marks will be produced on the outer surface of the guardrail when it is hit by some larger impacts; 2. When the existing guardrail is in use, since the height of the guardrail is fixed, it is used on some uneven roads. When it is in a concave place, the guardrail cannot be found in time from a distance. Therefore, the guardrail needs to increase the height adjustment structure to ensure that the guardrail is visible. We have launched a new road safety guardrail. Utility Model Content
