Description

Technical Field

[0001] The utility model belongs to the technical field of construction maintenance, and particularly relates to a guardrail capable of quickly adjusting a protection area. Background Art

[0002] In municipal construction, due to the large number of pedestrians and vehicles in the construction area, in order to improve the safety of construction work in the construction area, and to serve as a warning to pedestrians and vehicles, most municipal construction areas are currently enclosed by spliced ​​fences or guardrails. The bottom of the guardrail is cast in concrete and cannot be moved as a whole. Only when the construction of the node is completed, the concrete building base and guardrail are removed as a whole. The guardrail cannot be quickly adjusted according to the progress of the construction. On the one hand, it occupies the use of the guardrail, and on the other hand, the long-term enclosure area affects the speed of pedestrians and vehicles. After searching, the patent with application number 202023074026.0 discloses a guardrail that can quickly adjust the protection area, including a column, a movable adjustment mechanism is installed at the bottom of the column, and a first guardrail and a second guardrail are movably installed on the column respectively, the first guardrail is arranged on the column through a rotating ring, and the second guardrail is arranged on the column through a rotating seat and the rotating ring is located on the inner side of the rotating seat; a first limiting mechanism is installed at the bottom of the first guardrail, and a second limiting mechanism is installed in the second guardrail, the first limiting mechanism cooperates with the second limiting mechanism and the first guardrail and the second guardrail are detachably connected.

[0003] However, during actual use, the applicant found that when adjusting the protection area, the protection area was adjusted by rotating and adjusting the positions of the first guardrail and the second guardrail, and the length of the guardrail could not be adjusted according to the protection requirements. In view of this, we propose a guardrail that can quickly adjust the protection area. Utility Model Content
