Description

Technical Field

[0001] This utility model relates to the field of iron horse fencing technology, specifically to an iron horse with an adjustable effective enclosure area. Background Technology

[0002] Iron barricades are temporary or permanent guardrail systems made primarily of steel. They typically consist of posts, beams, and connectors, which are assembled to form a continuous barrier structure. They are mainly used to separate and guide traffic areas, such as driveways, sidewalks, and construction zones, to ensure smooth and orderly traffic and reduce traffic accidents. Setting up iron barricades in dangerous areas or construction sites can protect pedestrians and vehicles from accidental injuries and improve safety.

[0003] There are various types of iron horse guardrails, including road construction guardrails, pedestrian isolation guardrails, and event site fences, but existing iron horse guardrails have certain inconveniences in use;
