Protective rod structure for safety fence of construction site

Abstract

The utility model provides a protective rod structure for a safety fence of a construction site, which comprises a rod body, the upper end and the lower end of the rod body are provided with accommodating grooves, each accommodating groove is internally connected with an insertion rod in a sliding manner, and each accommodating groove is internally provided with a limiting assembly for preventing the insertion rod from over-displacement; limiting bolts are detachably arranged at the upper end and the lower end of the rod body in a penetrating mode, and a first positioning hole and a second positioning hole which are matched with the limiting bolts are formed in the inserting rod in the vertical direction at intervals. When the limiting bolt penetrates through the rod body and the first positioning hole, the free end of the insertion rod is located in the storage groove. When the limiting bolt penetrates through the rod body and the second positioning hole, the free end of the inserting rod is located outside the containing groove. Connecting grooves matched with the inserting rods are formed in the two sides of the rod body, and connecting holes corresponding to the connecting grooves in a one-to-one mode and matched with the limiting bolts are formed in the rod body. The safety fence is compact in structure, novel in conception, convenient to store, not prone to being lost, capable of being directly assembled into the safety fence, convenient and fast to use and suitable for being used and popularized.
