At the same time, the cover plate is closed and the baffle is locked with the cooperation of the locking assembly, so as to realize the installation of the guardrail. When disassembly is required, the locking assembly is unlocked, the cover plate is opened, the baffle is removed, and the horizontal plate is moved upward until the horizontal plate is separated from the vertical column, and then the horizontal plate is folded, thereby realizing the disassembly of the guardrail and facilitating the transportation of the guardrail.

[0004] However, in actual use of the above-mentioned equipment, multiple protective plates are set to lock and fold, so that the guardrail can be installed and disassembled for easy transportation, but the workload of assembling multiple protective plates is large, and the guardrail cannot be switched according to the area to be protected, thereby reducing the convenience of using the guardrail; in view of this, we propose a construction project guardrail that is easy to carry.

[0024] In the embodiment of the utility model, an adjustment groove 5 is provided on the surface of the guardrail 1, and a moving block 6 is slidably connected to the inner wall of the adjustment groove 5. A positioning hole 7 is provided on the surface of the guardrail 1, and a threaded hole 8 is provided on the surface of the moving block 6. The inner wall of the threaded hole 8 is threadedly connected to a bolt 9. The surface of the column 2 4 is rotatably connected to a rotating shaft 10, and a handle 11 is fixedly connected to the outer surface of the rotating shaft 10. A through hole 12 is penetrated through the surface of the handle 11, and the inner wall of the through hole 12 is adapted to the inner wall of the fixing hole 13. The inner wall of the fixing hole 13 is threadedly connected to a threaded rod 14, and the end of the threaded rod 14 is fixedly connected to a turntable 15, and the threaded rod 14 is threadedly connected to the matching hole 16.

[0025] In one embodiment of the utility model, a side of the moving block 6 away from the adjusting groove 5 is fixedly connected to the outer surface of the guardrail 2, the outer wall of the bolt 9 is threadedly connected with the positioning hole 7, the adapter hole 16 is opened on the side of the column 3 away from the guardrail 1, the inner wall of the through hole 12 is threadedly connected with the outer wall of the threaded rod 14, the center of the adapter hole 16 is on the same horizontal line as the center of the rotating shaft 10, the surface of the handle 11 is fixedly connected with an anti-slip protrusion 17, the upper and lower sides of the guardrail 1 are provided with adjusting grooves 5, the two groups of adjusting grooves 5 are respectively connected to the guardrail 2 2 through the two groups of moving blocks 6, a plurality of groups of positioning holes 7 are opened, and the plurality of groups of positioning holes 7 are equidistantly distributed on the upper and lower sides of the guardrail 1 and penetrate into the interior of the adjusting groove 5.

[0026] In the utility model, when in use, the column 1 3 and the column 2 4 support the guardrail 1 and the guardrail 2 2, and the guardrail 1 and the guardrail 2 2 form a whole guardrail for protection at the construction site of the construction project. When the guardrail needs to be moved as a whole, the operator first manually rotates the upper and lower groups of bolts 9, so that the bolts 9 gradually disengage from the inside of the threaded hole 8 and then from the positioning hole 7, thereby releasing the limit of the moving block 6 in the adjustment groove 5, and then pushes the guardrail 2 2, the guardrail 2 2 will drive the moving block 6 to slide in the inside of the adjustment groove 5, so that the guardrail 2 2 moves parallel to the surface of the guardrail 1, so that the guardrail 1 and the guardrail 2 2 are in a stacked state, at this time, the bolt 9 is inserted into the corresponding positioning hole 7 and rotated forward to fix the moving block 6 after moving the position, and finally the turntable 15 is manually held to reverse, so that the threaded rod 14 is disengaged from the fixing hole 13, and the handle 11 is manually deflected.
