Compound guardrail with protective function

Abstract

The invention discloses a compound guardrail with a protective function. The compound guardrail comprises five outer pipes, inner pipes are movably arranged on the upper surfaces of the outer pipes inan inserting mode, threads are arranged on the side faces of the inner pipes, and the inner pipes are connected with fixed nuts in a threaded mode through the threads. The lower surfaces of the fixednuts are in contact with the upper surfaces of the outer pipes, the lower ends of the side faces of every two adjacent outer pipes are fixedly connected through a first cross rod, the upper ends of the side faces of every two adjacent outer pipes are fixedly connected through a second cross rod, the upper ends of the side faces of every two adjacent inner pipes are fixedly connected through a third cross rod, and connecting rods are arranged on the side faces of the outer pipes at the left and right ends. Moving seats are arranged at the ends, away from the outer pipes, of the connecting rods, and cone parts are movably arranged at the lower ends of the outer pipes in an inserting mode. The compound guardrail with the protective function is simple in structure and capable of moving, the height can be adjusted, fixing is convenient, the stability is good, guardrails can be prevented from falling, the protective function is achieved, the use is convenient, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of guardrails, in particular to a composite guardrail with protection function. Background technique [0002] Guardrails are mainly used for the protection and protection of equipment and facilities in factories, workshops and warehouses, and in the event of power maintenance, road maintenance and construction, and damage to road manhole covers, it is necessary to fence the work area through guardrails. It plays a protective role and prevents pedestrians from being hurt. However, due to the low height of the existing guardrail and it is placed on the ground through the support of the base, it is easy to be knocked down and cannot play a protective role. Moreover, because the guardrail cannot be moved, it is very uncomfortable to carry. Convenience. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a composite guar...
