Description

Technical Field

[0001] The utility model relates to the technical field of safety fences, in particular to a safety fence with a telescopic function. Background Technique

[0002] Safety fences can be divided into soft mesh fences and rigid fences. The mesh fences are divided into ordinary polypropylene high-strength wire meshes and polyester mesh fences. Safety fences are used in various construction sites, roadblocks, and warning areas. Especially for some small-scale ground depressions, the safety fence net can play a role in protecting pedestrians.

[0003] Currently, safety fences are usually used in various construction sites, roadblocks, and warning areas in a telescopic manner. However, existing workers have found that for small-area ground defects or warning areas in circular ranges such as manhole covers, when placing existing safety fences, there are certain blind spots. Traditional telescopic safety fences are linear, and there will be certain defects when using traditional safety fences for circular warning areas. Therefore, we propose a safety fence with a telescopic function again. Content of the Utility Model
