The utility model discloses an assembled stair temporary edge self -locking type protective fence, including a plurality of stand, two adjacent stand between being equipped with two horizontal block subassembly setting in upside and downside, be equipped with self -locking subassembly on the stand, and the horizontal block subassembly is connected through the self -locking subassembly between the stand, and the bottom of stand is equipped with connecting component, and two upside and downside horizontal block subassembly between being equipped with reinforcing component, through the self -locking subassembly in, spring pushes the positioning column and the positioning hole of horizontal block subassembly and is connected, forms stable self -locking structure, can
resist external force
impact, avoids horizontal block subassembly and stand accidental uncoupling, and the protection reliability is improved obviously, through the bar, can control the positioning column telescopic fast, realizes horizontal block subassembly and the quick
assembly and disassembly of stand, and the connecting component is adjusted by screw rod and is clamped, can be fixed on the stair step fast, need not
welding or complex bolt operation, and the installation time is greatly shortened, and the cover of anti -drop piece and the convex column form annular cavity, limit the bar displacement, avoid the positioning column and separate the through -hole because of accidental stress.
