Description

Technical Field

[0001] This utility model relates to the field of safety fence technology, and in particular to a safety fence that can be installed quickly. Background Technology

[0002] In construction sites and other similar locations, safety fences can isolate the construction area from the outside world, preventing non-construction personnel from entering and avoiding injuries from falling objects, machinery operations, and other hazards. During road construction, fences can guide pedestrians and vehicles away from dangerous areas, ensuring public safety.

[0003] A search revealed a quick-installation safety fence (publication number CN221823528U) comprising a base, fence posts, fence mesh, and connecting seats. The base has mounting holes on both sides, a slot in the center of the top of the base, and slots on both sides of the slot. The fence post is mounted on the top of the base. This invention allows for quick assembly of the base and fence post by inserting a block at the bottom of the fence post into the slot at the top of the base, while simultaneously engaging the slots on both sides of the block. For disassembly, rotating a shaft on the fence post causes a second pull rope to pull a rotating roller, which in turn moves a movable plate and the locking blocks via first pull ropes on both sides. Once the locking blocks are removed from the slots in the slot, the fence post can be quickly disassembled.

[0004] Based on the aforementioned patent, by rotating the pivot on the fence post, the pivot can pull the rotating roller through the second pull rope. At the same time, the rotating roller can drive the movable plate and the locking block to move through the first pull ropes on both sides. When the locking block is pulled out of the slot on the slot, the fence post can be quickly disassembled. However, in the actual installation process, due to factors such as site terrain and building structure, the fence often needs to be adjusted according to the specific situation. This installation method makes it difficult to adjust the angle between fences, which may make the installation process difficult and increase installation time and labor costs.

[0005] Therefore, to address the existing problem of difficulty in adjusting the angle between fences, a fast-installing safety fence is needed to solve the aforementioned problem. Utility Model Content

[0006] To address the difficulty in adjusting the angle between fences in existing technologies, this application provides a quick-installation safety fence. By pulling the sliding rod and engaging the rotating frames on both sides into the fixed frame, the installation between fences can be completed. Simultaneously, pulling the pull rod allows the rotating frames to be rotated, adjusting the angle between the installed fences. This allows the fence to be quickly adjusted to a suitable angle according to different site terrains, usage requirements, and surrounding environments, thus improving the fence's adaptability.

The inner wall of the fence body 6 is slidably connected to the outer wall of the base 1. The inner wall of the rotating frame 14 is provided with slots 15. The outer walls of the sliding rod 9 are fixedly connected with blocks 10, the shape of which matches the slots 15. A limit rod is slidably connected to the inner wall of the fixed frame 8. 11. A spring 12 is fixedly connected to the left end of the limiting rod 11. The other end of the spring 12 is fixedly connected to the inner wall of the fixed frame 8 for disassembly and assembly between the fence bodies 6. Multiple grooves 19 are provided on both sides of the inner wall of the fixed rod 13. A slider 17 is slidably connected to the inner wall of the rotating frame 14. The shape of the slider 17 matches the groove 19. A pull rod 16 is fixedly connected to the front end of the slider 17. A spring 2 18 is fixedly connected to the left end of the pull rod 16. The other end of the spring 2 18 is fixedly connected to the inner wall of the rotating frame 14 for adjusting the angle of the rotating frame 14.

[0034] Specifically, during disassembly, pulling the limiting rod 11 and the sliding rod 9 removes the locking blocks 10 on both sides from the locking slots 15, allowing the rotating frame 14 to be removed from the fixed frame 8, thus completing the disassembly of the fence body 6. By pulling the sliding rod 9 and locking the rotating frames 14 on both sides into the fixed frame 8, the installation of the fence is completed. At the same time, pulling the pull rod 16 rotates the rotating frame 14, adjusting the angle between the installations. This allows the fence to be quickly adjusted to a suitable angle according to different site terrains, usage requirements, and surrounding environment, improving the fence's adaptability.

[0035] refer to Figures 4-6 As shown in Embodiment 2: Limiting blocks 2 are slidably connected to both sides of the inner wall of the base 1. The fence body 6 is slidably connected to the inner wall of the limiting blocks 2. The lifting assembly includes a toothed plate 3 fixedly connected to the opposite side of the outer wall of the limiting blocks 2. Gears 4 are meshed to the outer wall of the toothed plate 3. The bottom end of the gears 4 is rotatably connected to the inner wall of the base 1. Multiple limiting grooves 7 are opened on the inner wall of the fence body 6. The shape of the limiting blocks 2 matches the limiting grooves 7. A torsion spring 5 is fixedly connected to the top of the gears 4. The other end of the torsion spring 5 is fixedly connected to the inner wall of the base 1 for adjusting the height of the fence body 6.

[0036] Specifically, a through hole is provided at the bottom of the base 1. The base 1 is fixed to the ground by passing a bolt through the through hole. The height of the fence body 6 can be adjusted by pressing the limit block 2 on one side, so as to meet the changes in different construction progress and adjust its height flexibly to meet the needs of these different stages and reduce the possibility of safety accidents.

[0037] Working principle: First, during installation between the fence bodies 6, simply pull the sliding rod 9 and the limiting rod 11 to engage the rotating frames 14 on both sides into the fixed frame 8. After installation, press down on the sliding rod 9 to engage the locking block 10 into the locking groove 15, and release the limiting rod 11. Spring 12 then engages the limiting rod 11 against the outer wall of the sliding rod 9, limiting its position. Next, by pulling the pull rods 16 on both sides, the slider 17 moves, allowing it to be removed from the groove 19. This allows the rotating frame 14 to be rotated to adjust the angle between the fence bodies 6. After adjustment, release the pull rods 16. Spring 18 is used to engage slider 17 into groove 19, limiting the rotation frame 14. At the same time, when the height of the fence body 6 needs to be adjusted, simply press the front or rear limiting block 2. The limiting block 2 on one side slides inward and drives the toothed plate 3 to move. Through the meshing gear 4 and toothed plate 3, the limiting block 2 on the other side slides inward synchronously. The limiting blocks 2 on all four sides are removed from the limiting groove 7, and the fence body 6 can be pulled to adjust its height. After the adjustment is completed, the torsion spring 5 drives the gear 4 to rotate in the opposite direction, engaging the limiting block 2 into the limiting groove 7 to limit the fence body 6.
