Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a fence that is convenient to adjust. Background Art

[0002] A building construction fence is a safety protection facility used in construction sites, road construction, public places and other places, and usually consists of a fence body, support columns, connecting pieces, etc. The building construction fence can effectively protect the safety of the construction site and the public and prevent accidents from occurring.

[0003] The patent with the publication number of CN220979045U discloses a building construction fence, which includes a first base, a first support column and a second support column. A fixed rod is fixedly connected to the upper surface of the first base, and the outer surface of the fixed rod is rotatably connected to the inner wall of the first support column. A second base is fixedly connected to the lower surface of the second support column. This device enables personnel to adjust the length of the construction fence according to actual needs and fix it under the action of bolts, avoiding the need for multiple fixed fences to block the construction site and improving the blocking effect of the building construction fence. However, this device uses the universal wheels at the bottom of the second support column to slide the inner railing out from the surface of the outer railing, and then uses structures such as bolts and second holes to fix and limit the outer railing and the inner railing, so as to achieve the purpose of adjusting the length of the fence. But actually, after using this building construction fence to enclose the construction site, since the outer railing, the inner railing, the first support column and the second support column form a whole, if the construction personnel want to reach the opposite side of this fence for construction, either directly climbing over the fence is likely to cause threatening accidents, or bypassing the fence will affect the construction efficiency. Therefore, a fence that is convenient to adjust is proposed to solve the problem that most of the existing building construction fences are integrated, resulting in reduced convenience.

One side of the rotatable fence frame 4 is provided with an adjusting mechanism 7. Connecting grooves 8 are provided at the tops of the two adjusting fence frames 5. The inner cavity of the connecting groove 8 is provided with an I-shaped limiting plate 9. The top of the I-shaped limiting plate 9 is fixedly connected with a pulling ring 10.

[0024] Furthermore, there is a certain gap between the two opposite adjusting fence frames 5, and strong magnets are provided on the opposite end faces of the two adjusting fence frames 5.

[0025] Further, the two adjusting fence frames 5 are connected by using I-shaped limit plates 9 and connecting grooves 8. There is a minimum frictional force between the I-shaped limit plates 9 and the connecting grooves 8 to keep the two relatively stationary. The gap between the adjusting fence frames 5 ensures that the rotatable fence 4 can rotate smoothly. When a construction worker passes by, the two adjusting fence frames 5 can quickly approach and be parallel by cooperating with the strong magnets on the opposite surfaces, and then cooperate with the I-shaped limit plates 9 and the connecting grooves 8 for connection to continue to enclose the construction site.

[0026] Further, the adjusting mechanism 7 includes a number of card slots 701 opened on one side of the adjusting fence frame 5. A clamping plate 702 is arranged in the inner cavity of the card slot 701, and a chamfer 703 is opened on one side of the clamping plate 702.

[0027] Further, a U-shaped frame 704 is fixedly connected to one side of the rotatable fence 4. A connecting plate 705 is arranged in the inner cavity of the U-shaped frame 704. The clamping plate 702 penetrates through the inner cavity wall of the rotatable fence 4 and is slidably connected. The connecting plate 705 is fixedly connected to the clamping plate 702. A pull rod 706 is arranged in the inner cavity of the U-shaped frame 704, and a spring 707 is arranged on the outer ring of the pull rod 706. When the width of this fence needs to be adjusted, according to the enclosure requirements of the construction site, the fence posts 1 and the second fence posts 2 are pulled outwards. By cooperating with the chamfer 703 on the clamping plate 702 and the card slot 701 on the adjusting fence frame 5, the clamping plate 702 together with the connecting plate 705 compresses the spring 707 outwards. After reaching the required width, the clamping plate 702 automatically enters the card slot 701 by cooperating with the spring 707, and the adjusting fence frame 5 will not retract, so as to achieve the purpose of adjusting the width of the fence.

[0028] Further, a pull frame 708 is arranged on one side of the U-shaped frame 704. The pull rod 706 penetrates through the U-shaped frame 704 and is slidably connected.
