Their main functions are to delineate work areas, isolate hazardous sources, and guide the flow of people and vehicles, thereby effectively preventing accidents and ensuring the safety of construction workers and the public.

[0003] However, traditional construction fences are mostly made of metal or hard plastic. These fences are bulky and heavy, which makes transportation, handling and storage costly and inconvenient. Secondly, their installation and dismantling process is cumbersome and inefficient. In addition, the hard material lacks cushioning when it encounters accidental collisions, which can easily cause secondary injuries to people or equipment. At the same time, the fences themselves are also easily deformed and damaged by collisions.

[0004] Therefore, there is an urgent need for a method that integrates efficient counterweight stabilization, good buffering performance, and the ability to... Utility Model Content

[0005] The purpose of this utility model is to provide a construction safety fence that is easy to install and transport, and can also provide cushioning protection for personnel in the event of an impact.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a construction safety fence, including a base, an extension fence fixedly connected to the base, a cavity for accommodating a counterweight filling medium inside the base, an addition port communicating with the cavity on the base, an air storage chamber inside the extension fence, evenly distributed ventilation openings on the extension fence, and an inflation / deflation connector communicating with the air storage chamber installed on the extension fence.

[0007] Preferably, the top of the raised railing is fixedly connected with multiple fixing straps, each of which has a through hole, and a limit rope is provided inside the multiple through holes.

[0008] Preferably, a plurality of first connecting straps are fixedly connected to one side of the base and the raised railing, and a plurality of second connecting straps that match the first connecting straps are fixedly connected to the other side of the base and the raised railing.

[0009] Preferably, a base pad is fixedly connected to the bottom surface of the base, and the base pad has multiple fixing holes. Each fixing hole is equipped with a grounding rod for reinforcing the base pad.

[0010] Preferably, each of the grounding rods is fixedly connected to a pressure seat at its top end, and each pressure seat is provided with a U-shaped groove.

[0011] Preferably, two sets of warning stickers are fixedly connected to the base, both sets of warning stickers are set as reflective stickers, and protective pads are fixedly connected to the left and right sides of the base.

[0012] Preferably, the base has multiple reinforcing ribs fixedly connected inside, and the multiple reinforcing ribs are evenly distributed in the cavity.

[0013] Preferably, the filling port is located at the top of the base, a first sealing cap is installed in the filling port, the base has a discharge port located at the bottom of the base, and a second sealing cap is installed inside the discharge port.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: The device is made of soft material, which can significantly reduce the overall weight of the fence, making it easy to store and transport. The base has a cavity that can be filled with counterweight medium. During installation, water can be added through the top inlet to quickly unfold and complete the counterweight. Its installation does not require complicated fixing operations, which is both convenient and cost-effective. By setting an air storage chamber in the raised fence and using an air inflation / deflation connector, it can be quickly inflated and formed. After installation, both the base and the raised fence have good cushioning performance, which can effectively absorb impact force during collisions and improve collision safety. After deflation, the volume of the raised fence is greatly reduced, and it can be stored together with the base, which greatly saves storage and transportation space. Therefore, this fence is particularly suitable for temporary construction, emergency isolation, and scenarios that require frequent movement. Attached Figure Description

[0018] 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.

[0019] Example: Figure 1-4 As shown, this utility model provides a construction safety fence, including a base 1. The base 1 has an internal cavity 4 for accommodating counterweight filling material. An inlet connected to the cavity 4 is located on the top of the base 1, and a first sealing cap 6 is installed in the inlet. An outlet is located on the bottom of the base 1, and a second sealing cap 8 is installed inside the outlet. The cavity 4 can be filled with counterweight materials such as water or sand. By increasing the overall mass of the base 1, the fence's resistance to tipping and wind is significantly improved. The inlet at the top, combined with the first sealing cap 6, facilitates rapid filling and sealing. The outlet at the bottom and the second sealing cap 8 allow for quick and complete emptying of the material after construction, facilitating transportation and reuse.

[0020] An extension bar 2 is fixedly connected to the base 1. The extension bar 2 has an internal air storage chamber 5 and evenly distributed ventilation openings 3. An inflation / deflation connector 7, connected to the air storage chamber 5, is installed on the extension bar 2. Inflation of the air storage chamber 5 via the connector 7 allows the flexible extension bar 2 to unfold quickly and achieve sufficient rigidity, forming an effective protective barrier. The ventilation openings 3, when inflated, effectively reduce wind resistance and improve stability in inclement weather. When deflated, they facilitate quick folding and storage, saving storage and transportation space.

[0021] Furthermore, the top of the raised platform 2 is fixedly connected with multiple fixing straps 11, each of which has a through hole, and a limit rope 12 is installed inside the multiple through holes. The fixing straps 11 and the limit rope 12 work together to fix the raised platform 2 from the top, which can further improve its reliability and prevent it from tipping over.

[0022] Multiple first connecting straps 9 are fixedly connected to one side of both the base 1 and the raised fence 2, and multiple second connecting straps 10 that match the first connecting straps 9 are fixedly connected to the other side of both the base 1 and the raised fence 2. The first connecting straps 9 and the second connecting straps 10 are used for quick connection and fixation between adjacent fence units, and can be flexibly combined into continuous isolation strips to adapt to the enclosure requirements of construction areas of different lengths and shapes.

[0023] A base pad 13 is fixedly connected to the bottom surface of the base 1. Multiple fixing holes 14 are provided on the base pad 13, and a ground-inserting rod 15 is installed inside each fixing hole 14 to reinforce the base pad 13. A pressure seat is fixedly connected to the top of each ground-inserting rod 15, and each pressure seat has a U-shaped groove 16. The base pad 13 increases the contact area with the ground, improving overall stability; the fixing holes 14, in conjunction with the ground-inserting rods 15, further secure the fence to the ground, enhancing its resistance to displacement in strong winds or sloping environments; the U-shaped groove 16 on the top of the pressure seat facilitates the removal of the ground-inserting rod 15, improving operational convenience.

[0024] Two sets of warning stickers 17 are fixedly connected to the base 1. Both sets of warning stickers 17 are reflective. Protective pads 19 are fixedly connected to both the left and right sides of the base 1. The reflective warning stickers 17 can reflect light at night or in low light conditions, significantly improving the visibility and warning effect of the fence and reducing the risk of accidental collisions.

[0025] The base 1 has multiple reinforcing ribs 18 fixedly connected inside, and these ribs 18 are evenly distributed in the cavity 4. The reinforcing ribs 18 are used to enhance the structural strength and overall rigidity of the base 1 after the counterweight is filled, prevent the cavity 4 from expanding and deforming, extend its service life, and ensure safe use.

[0026] Working principle: During use, water can be injected into the cavity 4 through the filling port on the base 1 to act as a counterweight medium, increasing the overall weight and lowering the center of gravity. Gravity ensures the stability of the fence. Afterwards, air can be injected into the air storage chamber 5 inside the raised fence 2 through the air filling and defilling connector 7 to expand it into a rigid three-dimensional barrier, achieving the enclosure function. The evenly distributed ventilation openings 3 on its surface can effectively reduce wind resistance and enhance wind resistance stability. The first connecting strap 9 and the second connecting strap 10 can be tied together to quickly connect multiple devices into a continuous isolation strip to adapt to construction areas of different sizes. To enhance its stability, a ground-inserting rod 15 can be inserted into the ground through the fixing hole 14 on the base pad 13 at the bottom of the base 1, and the limiting rope 12 can be tightened externally and inserted into the through hole on the fixing strap 11 to further enhance wind resistance and displacement resistance. After use, the water and gas can be emptied, and the device can be folded and compressed to its minimum volume for easy transportation and storage.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
