[0003] The main function of construction safety barriers is to isolate the construction area from surrounding pedestrians, vehicles, and other non-construction areas, preventing unauthorized personnel and vehicles from entering the construction site and avoiding harm from various potential hazards during construction, such as falling objects from heights and risks associated with machinery operation.

[0004] Existing construction safety fencing technologies often employ inconvenient folding techniques, resulting in significant space consumption during transportation and increased logistics costs and difficulties. Furthermore, the cumbersome assembly and disassembly processes are labor-intensive and time-consuming, impacting construction progress. Therefore, a multifunctional construction safety fencing solution is proposed to address these issues. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of a multifunctional construction safety protective fence, comprising two support plates 1, which serve as a basic frame. A main plate 2 is rotatably connected to one side of each support plate 1. Rotating components are fixedly connected to both sides of the main plate 2. Each rotating component includes multiple fixed posts 8, and a pawl 5 is rotatably connected inside each fixed post 8. One end of the pawl 5 is rotatably connected to a second pawl 6, and the two work together to rotate. The other end of the pawl 5 is rotatably connected to a slider 7. The outer wall of the slider 7 is slidably connected to the inner wall of the fixed post 8 to ensure rotational stability. A groove 14 is formed at the bottom of the support plate 1, and the bottom of the groove 14 is slidably connected to a placement block 15. A moving block 18 is slidably connected inside the placement block 15. A groove 20 is formed on the outer wall of the main plate 2, and the groove 20 is slidably connected to a limiting block 19. The bottom of the moving block 18 is slidably connected to the top of the limiting block 19. A limiting spring 16 is fixedly connected to the bottom of the support plate 1, and a limiting block 17 is fixedly connected to the bottom of the limiting spring 16. The limiting spring 16 and the limiting block 17 have a limiting function to ensure that the placement block 15 runs stably within the specified range, avoids sliding and displacement, and provides a solid guarantee for the stability of the multi-functional construction safety protection fence.

[0034] Reference Figure 1 , Figure 2 and Figure 4 One side of the main board 2 is rotatably and flexibly connected to the short extension plate 3 via a rotating assembly, which allows the short extension plate 3 to be rotated 180 degrees. The other side of the main board 2 is rotatably connected to the long extension plate 4 via a rotating assembly with the same structure, which also allows the short extension plate 3 to be rotated 180 degrees. A latching assembly is fixedly connected inside the long extension plate 4, and correspondingly, a keyhole 11 is opened inside the short extension plate 3. The latching assembly uses a fixed block 12 as a frame structure. Two support springs 13 are symmetrically fixedly connected inside the fixed block 12. When no external force is applied, the two support springs 13 remain in a naturally extended state. When an external force is applied, they can elastically expand and contract according to the magnitude of the force, providing key power support for the operation of the entire latching assembly. The other end of the support spring 13 is fixedly connected to a lever 10. The lever 10 can slide inside the fixed block 12 under the elastic drive of the support spring 13. A locking tongue 9 is vertically fixedly connected to the bottom of the lever 10, and the outer wall of the locking tongue 9 is slidably connected to the inner wall of the fixed block 12. In practice, when it is necessary to expand the fence area, construction workers can operate the rotating component to rotate the long extension plate 4 and the short extension plate 3 synchronously by 180 degrees. When the two are precisely aligned, under the elastic force of the support spring 13, the lever 10 drives the locking tongue 9 to slide into the inner wall of the keyhole 11, completing the locking action. This connection method is not only easy to operate, but also can withstand greater external pulling force after connection, providing a solid guarantee for the stability of the fence in the expanded state, effectively meeting the needs of complex construction sites for flexible fence expansion.

[0035] Working Principle: When using the fence, the support plate 1 and main plate 2 must first be pulled to a vertical position. At this time, the moving block 18 will precisely engage with the limiting block 19 under the natural force of gravity, thereby fixing the support plate 1 and main plate 2 and ensuring the stability of the fence structure. Rotating components are fixedly connected to both sides of the main plate 2, connecting the short extension plate 3 and the long extension plate 4. The long extension plate 4 and the short extension plate 3 can rotate 180 degrees using pawl 1 5 and pawl 2 6. When it is necessary to expand the fence area, the long extension plate 4 and the short extension plate 3 can be rotated to the same plane as the main plate 2, effectively increasing the overall coverage area of ​​the fence. After the long extension plate 4 and the short extension plate 3 are rotated to the same plane as the main plate 2, the sliding paddle 10 will cause the locking tongue 9 to press against the support spring 13. Under the elastic reaction force of the support spring 13, the locking tongue 9 will be pushed and engaged in the keyhole 11. This action further fixes the extension plate and the main plate 2, ensuring the stability of the fence after assembly.

[0036] To extend the length of the fence, the placement block 15 and the limiting block 19 can be removed by sliding. When the fence length does not need to be increased, simply slide the placement block 15 to the designated position. At this time, the limiting spring 16 will release elastic potential energy to the limiting block 17, allowing the limiting block 17 to lock the placement block 15, thereby fixing it and ensuring that the fence remains at the required length, meeting the flexible needs for fence length in different scenarios.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
