Description

Technical Field

[0001] This utility model relates to the technical field of safety protection devices for building construction, specifically a safety protection fence for building construction. Background Technology

[0002] With the accelerating pace of urbanization, a large number of buildings are under construction. During construction, it is necessary to isolate the construction site to prevent personnel and vehicles from entering, thereby ensuring the safe and orderly progress of construction. Currently, construction site isolation generally uses methods such as plastic water-filled barriers, corrugated steel sheets, and brick walls. Existing technology discloses a construction safety barrier with authorization announcement number CN220599455U, comprising two bases. A bidirectional threaded rod is rotatably connected internally to each base. A bevel gear is fixedly connected externally to the bidirectional threaded rod. Threaded sleeves are threaded to both the front and rear sides of the bidirectional threaded rod. Two connecting rods are fixedly connected to opposite sides of the threaded sleeves on both sides. A support frame is fixedly connected to opposite sides of the connecting rods on both sides. An installation block is fixedly connected to the top of the base, and a lead screw is rotatably connected internally to the installation block. In this utility model, the height of the protective rod can be adjusted through the coordinated use of gears one and two, while increasing the contact area between the safety barrier and the ground. This not only improves stability but also flexibility, thereby enhancing economic efficiency.

[0003] However, existing construction safety barriers have been found to lack expandability during use, making it difficult to extend them vertically. This makes them unsuitable for adapting to different environments around the construction area, often requiring temporary heightening of the barriers, which is cumbersome. Utility Model Content

One end of the rotating shaft 14 is fixed to one side of the second baffle 4, and the other end of the rotating shaft 14 is fixedly installed with a gear 15. The first slider 6 is located on the side away from the second baffle 4. An arc-shaped toothed block 16 that meshes with gear 15 is slidably mounted on the first slider 6. A groove 17 is provided on one side of the first slider 6, and a second slider 18 is slidably mounted in the groove 17. One end of the second slider 18 is fixed to one side of the arc-shaped toothed block 16. A second lead screw 19 is threaded through the second slider 18. A cavity 20 is provided on the first slider 6. The top end of the second lead screw 19 extends into the cavity 20 and is provided with a first bevel gear 21. A rotating rod 22 is rotatably mounted on one side of the first slider 6. One end of the rotating rod 22 extends into the cavity 20 and is provided with a second bevel gear 23. The second bevel gear 23 meshes with the first bevel gear 21. This arrangement facilitates the adjustment of the angle of the second baffle 4, thereby enabling… To avoid obstacles, the applicability of the protective barrier is effectively improved. A threaded through hole is provided on the inner wall of the rectangular cover 11 on the side away from the limiting rod 8. The first lead screw 13 is threaded through the threaded through hole, facilitating the lateral movement of the first lead screw 13. A circular groove is provided on one side of the toothed block 12, and one end of the first lead screw 13 is rotatably installed in the circular groove, facilitating the rotatable connection between the first lead screw 13 and the toothed block 12.

[0038] The working principle of this utility model is as follows: In use, first, place the device in a suitable position, then fix the fixing plate 3 to the ground with bolts. Next, rotate the two first lead screws 13, causing the toothed block 12 to slide into the corresponding rectangular cover 11, disengaging the toothed block 12 from the rack 10. The first slider 6 is then released from its fixation. Then, pull the second baffle 4 upwards, causing the two rotating shafts 14 to rise. The rotating shafts 14 drive the first slider 6 to slide upwards within the corresponding rectangular through groove 5 until the second baffle 4 reaches the appropriate height. Then, rotate the two first lead screws 13 in the opposite direction, causing the toothed block 12 to re-engage with the rack 10. The first slider 6 is then fixed to the limiting rod 8, fixing the second baffle 4. The protective fence is then extended upwards. This design facilitates vertical expansion of the protective fence, adapting to different environments around the construction area and avoiding the problem of temporarily raising the fence. It effectively avoids cumbersome operations. To adjust the angle of the second baffle 4, first rotate the two rotating rods 22. The rotating rods 22 drive the second bevel gear 23 to rotate, the second bevel gear 23 drives the first bevel gear 21 to rotate, and the first bevel gear 21 drives the second lead screw 19 to rotate. This causes the second slider 18 to slide upward in the groove 17, causing the arc-shaped toothed block 16 to rise and disengage from the gear 15. The gear 15 is then released from its fixed position. Next, rotate the second baffle 4. The second baffle 4 drives the two rotating shafts 14 to rotate on the corresponding first slider 6. The rotating shafts 14 drive the gear 15 to rotate until the angle of the second baffle 4 is appropriate. Then, rotate the two rotating rods 22 in the opposite direction, causing the arc-shaped toothed block 16 to descend until it re-meshes with the gear 15, thus fixing the gear 15. The angle adjustment of the second baffle 4 is then complete. This design facilitates the adjustment of the angle of the second baffle 4, thereby facilitating obstacle avoidance and effectively improving the applicability of the protective barrier.
