Description

Technical Field

[0001] This utility model relates to the field of safety fencing technology, specifically a safety fencing for construction sites. Background Technology

[0002] Ensuring construction safety is paramount during construction site operations. To prevent unauthorized personnel from entering the construction area and avoid accidents, while also effectively isolating the construction area and ensuring construction order and the safety of the surrounding environment, safety fencing has become an indispensable safety protection facility for construction sites. However, traditional construction site safety fencing has some shortcomings in its design and use. Firstly, in terms of installation and relocation, traditional fencing often lacks flexible and convenient adjustment methods. For example, when adjusting the fencing position to adapt to different construction stages or site changes, the operation is cumbersome, consuming manpower and time, and reducing construction efficiency. Moreover, some fencing exhibits poor stability during relocation, making it difficult to guarantee the integrity and safety of the fencing structure during movement.

[0003] The prior art provides a modular safety fence for construction sites that is easy to assemble, disassemble and transport (Announcement No.: CN222772011U). The device has a front folding plate seat (3) and a rear folding plate seat (7) respectively set at the lower end of the left column (1). The front folding plate seat (3) and the rear folding plate seat (7) are fixed to the lower end of the left column (1) in a front-to-back manner. A front 90-degree folding plate (4) is hinged on the front folding plate seat (3). A front universal wheel seat (5) is connected to the front 90-degree folding plate (4). A front universal wheel (6) is set on the front universal wheel seat (5). The left column (1), the left side long strip frame fence unit (15), multiple middle long strip frame fence units (16), the right side long strip frame fence unit (22) and the right column (2) form an integral fence.

[0004] However, the device still has the following drawbacks:

[0005] When this device is in use, the rotating plate lacks a limit switch. When the casters are in contact with the ground, the rotating plate becomes unstable, which prevents the casters from maintaining stable contact with the ground and affects the stability of the device. Therefore, we need to propose a safety fence for construction sites. Utility Model Content

The limiting mechanism limits the rotating plate in different usage states to prevent the rotating plate from rotating during use.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A construction site safety fence, comprising:

[0009] Two symmetrically distributed support columns are provided, and two symmetrically distributed mounting blocks are fixedly connected to the side walls of the two support columns.

[0017] Each of the two support columns has a sliding disk slidably connected inside, and the upper end of each of the two sliding disks is hinged with an internally threaded tube. The internally threaded tube is movably connected to the support column, and the upper end of the internally threaded tube is provided with a hook. The internally threaded tube is provided with a rotating component for adjusting the position of the hook.

[0030] 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.

[0031] Please see Figure 1-4 This utility model provides a technical solution:

[0032] A construction site safety fence, comprising:

[0033] Two symmetrically distributed support columns 1 are provided. Two symmetrically distributed mounting blocks 4 are fixedly connected to the side walls of the two support columns 1. Rotating plates 5 are rotatably connected inside the mounting blocks 4. The rotating plates 5 are in contact with the two support columns 1 respectively. The side walls of the two rotating plates 5 are provided with limiting mechanisms 7 for limiting the rotation plates 5.

[0034] Both support columns 1 are equipped with anti-loosening mechanisms 8 to limit the movement of the enclosure panel 3 when it is stored.

[0035] For example, a self-locking caster wheel 6 is provided on the side wall of the rotating plate 5. When the self-locking caster wheel 6 contacts the ground, it is convenient to adjust the position of the device.

[0036] The limiting mechanism 7 includes a limiting frame 71, a fixing bolt 74, a threaded hole 75, and a guide assembly;

[0037] Among them, the side walls of the two support columns 1 are slidably connected to limit frames 71, the two limit frames 71 are slidably connected to multiple rotating plates 5 respectively, and the inside of the limit frame 71 is provided with a guide component to guide the limit frame 71.

[0038] The limiting frame 71 is equipped with fixing bolts 74 inside, and two threaded holes 75 are evenly distributed on the side walls of the two support columns 1. The two threaded holes 75 are threadedly connected to the two fixing bolts 74 respectively.

[0039] For example, two threaded holes 75 at different positions cooperate with the fixing bolts 74, so that the fixing bolts 74 can fix the limiting frame 71 at different positions, and the limiting frame 71 can limit the rotation plate 5 in different usage states.

[0040] The guide assembly includes a groove 72 and a fixing strip 73;

[0041] The limiting frame 71 has two symmetrically distributed sliding grooves 72 inside, and each of the sliding grooves 72 has a fixing strip 73 slidably connected inside, and the fixing strip 73 is fixedly connected to the two support columns 1 respectively.

[0042] For example, the fixing strip 73 is fixed to the side wall of the support column 1. When the limiting frame 71 is raised or lowered, the fixing strip 73 slides inside the slide groove 72 to guide the limiting frame 71.

[0043] The anti-loosening mechanism 8 includes a sliding disc 81, an internally threaded tube 82, a hook 86, and a rotating assembly;

[0044] Among them, the two support columns 1 are slidably connected to the inside of the sliding disks 81, and the upper ends of the two sliding disks 81 are hinged to the internal threaded tubes 82. The internal threaded tubes 82 are movably connected to the support columns 1, and the upper end of the internal threaded tubes 82 is provided with hooks 86. The internal threaded tubes 82 are provided with a rotating component for adjusting the position of the hooks 86.

[0045] For example, the sliding disc 81 limits the internal threaded tube 82 to prevent the internal threaded tube 82 from detaching from the support column 1, and the two hooks 86 cooperate with each other to fix the position between the two support columns 1 and limit the stored mesh panel 3 to prevent the mesh panel 3 from loosening.

[0046] The rotating assembly includes a screw 83 and a rotating disk 85;

[0047] The internally threaded tube 82 is connected to a screw 83, the upper end of which is fixedly connected to a rotating disk 85, and the lower end of which is fixedly connected to a limiting disk 84. The limiting disk 84 is movably connected to the internally threaded tube 82.

[0048] For example, the angle of the screw 83 is controlled by the rotating disk 85, and the screw 83 and the internal threaded tube 82 undergo threaded movement, which facilitates the adjustment of the position of the rotating disk 85. The limiting disk 84 prevents the screw 83 from disengaging from the internal threaded tube 82.

[0049] The rotating disk 85 contacts the support column 1, and the rotating disk 85 is rotatably connected to the hook 86.

[0050] For example, the rotating disk 85 prevents the screw 83 from falling into the interior of the support column 1, and when the rotating disk 85 moves, it drives the hook 86 to move.

[0051] Multiple mesh panels 3 are evenly distributed between the two support columns 1, and the multiple mesh panels 3 are hinged to each other.

[0052] For example, the fence 3 isolates the construction site from the outside world to prevent outsiders from entering the construction site.

[0053] Two evenly distributed pins 2 are provided on the side walls of the two support columns 1, and multiple pins 2 are rotatably connected to the two enclosure panels 3 respectively.

[0054] For example, the pin 2 is used to install the mesh panels 3 at both ends.

[0055] Working principle: When using this utility model, loosen the fixing bolt 74 to release the limitation of the limiting frame 71, lift the limiting frame 71, rotate the rotating plate 5 to an angle parallel to the ground, and make the self-locking universal wheel 6 contact the ground. Then lower the limiting frame 71 to limit the rotating plate 5. The limiting frame 71 is then limited by the fixing bolt 74 and the threaded hole 75.

[0056] The fence panels 3 are hinged together, and the fence panels 3 at both ends are connected to the pins 2. The fence panels 3 are installed between the two support columns 1. By adjusting the position of the two support columns 1, the fence panels 3 are used to isolate the construction site from the outside world.

[0057] When storing the mesh panels 3, fold multiple mesh panels 3 together, pull out the internal threaded tube 82, rotate the angle of the internal threaded tube 82 so that the internal threaded tube 82 is parallel to the ground, rotate the rotating disk 85, the rotating disk 85 drives the screw 83 to rotate, which makes it easy to adjust the length of the screw 83 and the distance between the hook 86 and the internal threaded tube 82. Rotate the angle of the hook 86 so that the two hooks 86 rotate in opposite directions and the U-shaped notches of the two hooks 86 face each other. Rotate the rotating disk 85 to adjust the distance between the two hooks 86 so that the two hooks 86 are tightly hooked together, and fix the distance between the two support columns 1.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
