Problems solved by technology

The municipal road has a protective fence to prevent pedestrians from climbing over. Through the cooperation between the rotating shaft and the roller, when the pedestrian wants to climb over the protective fence and step on the surface of the roller, the roller will rotate, so that pedestrians cannot climb up through the protective fence. Climb, set rollers on the right side of the roof, so that pedestrians cannot get upward traction by grab...

Abstract

The invention relates to the field of municipal engineering, and aims to provide a protective fence with an anti-crossing function for municipal engineering; the protective fence comprises a lower protective fence body and an upper protective fence body, the lower protective fence body comprises a first stand column and a second stand column, a first base is welded to the bottom end of the first stand column, and a second base is welded to the bottom end of the second stand column. The protective fence has the beneficial effects that the lower protective fence body and the upper protective fence body are matched for use, so that the municipal engineering protective fence has a very good anti-crossing function, insertion plates are inserted into insertion grooves, connection between the protective fence bodies is more compact and stable, and through matched use of cylinders, forward threaded rods and reverse threaded rods, the cylinders drive the forward threaded rod and the reverse threaded rod to rotate in the adjusting screw holes, so that the distance between the lower protective fence body and the upper protective fence body can be adjusted according to needs, and the anti-crossing effect of the protective fence is further improved.

Description
