[0002] Fences are common in daily life and are a type of man-made barrier system. They are mainly used to define areas, provide security, or separate spaces. They can be flexibly adapted to the needs of scenarios such as agricultural enclosure, industrial security, garden landscape, and road isolation. They are an important infrastructure for spatial planning and safety management.

[0003] During road construction, it is necessary to use fences to shield the site and warn pedestrians to avoid danger. However, some construction sites are inconvenient for vehicles to enter, so manual labor is required to move the fences, which wastes a lot of manpower. Therefore, a lightweight fence is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing technologies have the disadvantage of requiring manual labor to move fences because it is inconvenient for vehicles to enter construction sites, which wastes a lot of manpower. Therefore, a lightweight fence is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lightweight fence includes two fixing mechanisms and multiple reflective strips disposed between the two fixing mechanisms. Each fixing mechanism includes a fixing cylinder, a counterweight box fixedly connected to the bottom of the fixing cylinder, and an installation shaft rotatably connected to the bottom inner wall of the counterweight box. The installation shaft rotatably passes through the fixing cylinder and extends to the top of the fixing cylinder. Multiple communicating guide boxes are fixed to one side of the fixing cylinder, and the guide boxes are through-hole on both sides. A first torsion spring is fixedly installed between the installation shaft and the counterweight box.

[0007] The multiple reflective strips pass through the guide box at the same height and are respectively wrapped around the circumference of the two mounting shafts at both ends;

[0008] Rollers are fixedly connected to one side of the outer wall of the counterweight box, and handles are fixedly connected to the top of the fixed cylinder.

[0009] The top of each fixed cylinder is equipped with a limiting component for limiting the installation shaft.

[0010] The outer wall of each fixed cylinder is fixedly equipped with multiple support mechanisms for supporting the fixed cylinder.

[0011] As a further embodiment of this utility model, the top of each counterweight box is fixedly connected to an L-shaped connecting block, with the two connecting blocks staggered vertically. Each connecting block has a through hole on its surface, and a pin is inserted into one of the through holes.

[0012] As a further embodiment of this utility model, the limiting component includes a top box and a ratchet. The top box is fixed to the top of the fixed cylinder. A through handle is rotatably connected to the top of the top box. A pawl is fixedly connected to the circumference of the handle. A second torsion spring is fixedly connected between the circumference of the handle and the top of the fixed cylinder. The ratchet is fixed to the top of the mounting shaft and engages with the pawl.

[0013] As a further embodiment of this utility model, the support mechanism includes a storage box, which is fixed to the outer circumference of the fixed cylinder. A rotating shaft is rotatably connected to the bottom of the storage box, and a support rod is fixedly connected to the circumference of the rotating shaft.

[0014] As a further embodiment of this utility model, the support mechanism also includes a guide sleeve and a mounting plate. The guide sleeve is fixed to one side of the outer wall of the storage box, and an insert plate is slidably connected inside the guide sleeve. The mounting plate is fixed to one end of the rotating shaft, and two insertion ports are opened on the circumference of the mounting plate.

[0018] In this application, during movement, the two counterweight boxes contact each other and are connected between the two connecting blocks via pins, thus connecting the two counterweight boxes. The entire device is tilted, and then the device is pulled and moved using a handle. This is convenient to use and reduces manual labor. After the device is moved to the workstation, it is unfolded. When unfolding, the device is placed vertically, and then the two fixed cylinders are pulled to both sides. With the reflective strip connected, the mounting shaft rotates, and the rotation of the mounting shaft drives the ratchet to rotate. Due to the ratchet pawl, the reflective strip will not retract after unfolding, making it convenient to use. After unfolding, the insert plate is pulled up, and then the support rod is lowered. The insert plate is then inserted into another socket to fix the support rod, increasing the product's wind resistance. After use, the engagement between the ratchet pawl and the ratchet is released, allowing the mounting shaft and reflective strip to return to their original positions.

[0019] Beneficial effects: In this utility model, the lightweight fence, through the design that allows the two fixed cylinders to be joined together, enables the product to be easily pulled and moved during the transfer process by means of handles and rollers, making it convenient to use and reducing manual labor;

[0020] In this utility model, the lightweight fence, by installing multiple support mechanisms on the outer wall of the fixed cylinder, enables the product to be supported by the support rods during use, thereby improving the product's wind resistance.

[0021] In this invention, the equipment can be easily pulled and moved by the combination of handle and roller, making it convenient to use and reducing manual labor. At the same time, the fixed cylinder can be supported by the support rod during use, which improves the product's wind resistance. Attached Figure Description
