[0002] The warning fence for construction projects is a safety facility used in construction sites. Its main purpose is to block risk areas and prevent people or objects from falling. At the same time, it serves as a warning to remind construction workers to pay attention to safety. This fence usually adopts yellow and black or red and white colors to make it easier to be noticed. In summary, the problems existing in the prior art are: there are two types of warning fences for construction projects: fixed to the ground and not fixed to the ground. The warning fence not fixed to the ground can be flexibly moved, which is convenient for mobile transportation and redeployment. However, the construction environment of the construction project is located outdoors, and the warning guardrail is easy to collapse due to wind or external force impact. If the weight of the warning guardrail is not adjusted, it is easy to cause the position of the warning fence to be unstable, causing safety hazards. However, the warning fences used in existing construction projects do not have components that are more stable in different construction environments. Therefore, a warning fence for construction projects is proposed to solve the above problems. Utility Model Content

If the weight of the warning fence is not adjusted, the position of the warning fence is likely to be unstable, causing safety hazards. However, the warning fences used in existing construction projects do not have a component that can be used more stably in different construction environments.

[0022] refer to Figure 3 The limiting device 6 includes two limiting tooth blocks 601, and the opposite sides of the two limiting tooth blocks 601 penetrate the device slot 2 and extend to the inner cavity of the counterweight slot 3. Three moving holes 602 are opened on the surface of the limiting tooth blocks 601. The inner cavity of the device slot 2 is fixedly connected with three moving rods 603 used in conjunction with the moving holes 602. The surface of the moving rod 603 is movably connected to the inner cavity of the moving hole 602. Two springs 604 are fixedly connected to the opposite sides of the two limiting tooth blocks 601, and the opposite sides of the two springs 604 are fixedly connected to the inner cavity of the device slot 2.

[0023] The above solution is adopted: by providing the limiting device 6 , when the counterweight block 4 moves to the inner cavity of the counterweight groove 3 , the limiting device 6 has a limiting effect on the position of the counterweight block 4 .

[0024] refer to Figure 4 The left and right sides of the limiting tooth block 601 are fixedly connected with an extrusion frame 7, the surface of the extrusion frame 7 is movably connected with an extrusion block 8, the extrusion block 8 is movably connected to the inner cavity of the device slot 2, and the surface of the extrusion control block 5 is in contact with the surface of the extrusion block 8.

[0025] The above solution is adopted: by providing the extrusion frame 7 and the extrusion block 8, when the extrusion block 8 moves, the extrusion frame 7 can be driven to move, and when the extrusion frame 7 moves, the limiting tooth block 601 can be driven to move.

[0027] The above solution is adopted: by setting the stabilizing hole 9 and the stabilizing block 10, when the extrusion block 8 moves, the stabilizing hole 9 will be driven to move along the surface of the stabilizing block 10. The coordinated use of the stabilizing hole 9 and the stabilizing block 10 has a limiting effect on the moving position of the extrusion block 8.

[0028] refer to Figure 4 The opposite sides of the two extrusion control blocks 5 are fixedly connected to the outer shell 11, the inner cavity of the outer shell 11 is movably connected to the inner shell 12, and the opposite sides of the two inner shells 12 are fixedly connected to the inner cavity of the device slot 2.

The coordinated use of the inner shell 12 and the outer shell 11 has a limiting effect on the moving position of the extrusion control block 5.

The docking rods 14 pass through the docking holes 15 and extend to the inner cavity of the device slot 2.

[0033] The above scheme is adopted: by setting the docking rod 14 and the docking hole 15, when the docking rod 14 moves to the inner cavity of the docking hole 15, the counterweight block 4 moves to the inner cavity of the counterweight groove 3, and the coordinated use of the docking rod 14 and the docking hole 15 has a limiting effect on the moving position of the counterweight block 4.

[0034] The working principle of this utility model:

[0035] When in use, when the warning fence 1 used in a construction project needs to be used more stably in different construction environments, the operator first pulls the extrusion control block 5 to the opposite side of the two extrusion control blocks 5. When the extrusion control block 5 moves, it will generate an extrusion force on the extrusion block 8. The extrusion block 8 subjected to the extrusion force will move to the side away from the inner shell 12. When the extrusion block 8 moves, it will drive the stabilizing hole 9 to move along the surface of the stabilizing block 10. When the extrusion block 8 moves, it will drive the extrusion frame 7 to move to the side away from the extrusion control block 5. When the extrusion frame 7 moves, it will drive the two limiting tooth blocks 601 to move to the side away from each other. When the limiting tooth block 601 moves, it will drive the moving hole 602 to move along the moving rod 6 03's surface moves, and the force generated when the limit tooth block 601 moves causes the spring 604 to undergo elastic deformation. When the limit tooth block 601 is completely moved to the inner cavity of the device slot 2, the docking rod 14 is moved to the inner cavity of the docking hole 15, and at the same time, the counterweight block 4 is driven to move to the inner cavity of the counterweight slot 3, and then the two extrusion control blocks 5 are released. The restoring force generated by the spring 604 restoring its shape will drive the limit tooth block 601 to be stuck into the inner cavity of the limit slot 13. The coordinated use of the limit tooth block 601 and the limit slot 13 has a limiting effect on the position of the counterweight block 4, and the setting of the counterweight block 4 has an adjusting effect on the weight of the warning fence 1. At this time, the warning fence 1 used in construction projects can be used more stably in different construction environments.

[0036] To sum up: the warning fence for construction projects, by setting a limit device 6, a movable hole 602, a movable rod 603, a spring 604 and a limit tooth block 601 for coordinated use, solves the problem that the existing warning fences for construction projects are of two types: fixed to the ground and not fixed to the ground. The warning fence not fixed to the ground can be flexibly moved, which is convenient for mobile transportation and redeployment. However, the construction environment of the construction project is located outdoors, and the warning guardrail is prone to collapse due to wind or external force impact. If the weight of the warning guardrail is not adjusted, the position of the warning fence is prone to be unstable, causing safety hazards. However, the warning fences used in existing construction projects do not have a component that is more stable for use in different construction environments.
