Description

Technical Field

[0001] This utility model relates to the field of safety fences, and more particularly to a foldable safety fence. Background Technology

[0002] Safety fences are a common temporary safety protection device, consisting of a support frame and barriers connected between the frames. Their core function is to prevent unauthorized personnel or vehicles from accidentally entering dangerous areas, thereby ensuring personnel safety, maintaining on-site order, and protecting equipment and property.

[0003] Existing technologies, such as the utility model patent with publication number CN204186139U, disclose a safety fence. This patent employs a fence unit comprising two posts and a cross-telescopic fence connecting the two posts. The cross-telescopic fence consists of multiple intersecting crossbars. Each post includes a base and a post body, with the post body vertically connected to the base. The base has vertically provided ground nail holes. The base is rectangular, and the side of the post body has a connecting plate and / or a connecting post protruding longitudinally from the surface of the post body. This utility model is small in size and easy to carry. Moreover, due to the use of high-quality epoxy resin and fiberglass materials, it achieves higher strength but lighter weight compared to traditional materials such as steel, iron, and aluminum alloys.

[0004] The inventors discovered the following problems in the use of safety fences during their daily work: the fences still occupy a large space after being stored, making transportation and storage inconvenient. The position of the supports and the way the fences are deployed are difficult to adapt flexibly to complex terrain. Especially when it is necessary to set up the fences along curved or irregular paths (such as the edge of equipment or curved sites), they often cannot fit tightly, resulting in blind spots or requiring a large number of additional parts to be spliced ​​together, which is inefficient. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as poor deployment flexibility and unsuitability for fencing operations along curved paths.

[0006] To solve the above technical problems, this utility model provides a foldable safety fence, comprising: a first support, a second support, an adjustment structure, and an auxiliary structure. The upper end of the first support is provided with an adjustment structure, which includes a connecting pipe and two adjustment brackets. The connecting pipe is rotatably connected to the first support. A connecting rod is slidably connected to the inner wall of the connecting pipe. A fixing frame is slidably connected to the lower end of the connecting rod. The fixing frame is fixedly connected to the first support. Two positioning holes are provided at the end of the connecting rod away from the fixing frame. Two positioning rods are slidably connected to the upper end of the second support. A lever is fixedly connected to the arc surface of each of the two positioning rods. A first spring is sleeved on the arc surface of each positioning rod. The two ends of the first spring are respectively fixedly connected to the second support and the lever. The positioning rod is fixedly connected to the inner diameter of the positioning hole. A cover frame is fixedly connected to the upper surface of each of the two adjusting frames. A connecting block is fixedly connected to the upper surface of the cover frame. The inner wall size of the connecting block is adapted to the connecting rod. Two rotating shafts are rotatably connected to the inner walls of each of the two adjusting frames. Several enclosure bands are fixedly connected to the arc surfaces of several rotating shafts. The enclosure bands are grouped in sets of three. The movable ends of two sets of enclosure bands are fixedly connected to each other, while the movable ends of the other two sets of enclosure bands are fixedly connected to the first and second supports, respectively. A second gear is rotatably connected to the upper surface of the adjusting frame. The teeth of the second gear mesh with two first gears. The first gears are fixedly connected to the arc surfaces of the rotating shafts.

[0007] The above components achieve the following effects: the overall structure of the fence can be quickly folded and unfolded, and can adapt to the fence requirements of curved or irregular areas by adjusting the angle of the adjustment frame and the linkage of the fence belt. It is easy to operate and has a stable structure.

[0008] Preferably, the connecting rod is a galvanized steel rod, and the connecting block is a galvanized steel block.

[0009] The above components achieve the following effects: the connecting rod and connecting block are made of galvanized steel, which has the advantages of high strength, rust resistance, and long service life.

[0010] Preferably, a handle is fixedly connected to the upper end of the rotating shaft, and the arc surface of the handle is provided with a plurality of anti-slip textures.

[0011] The effects achieved by the above components are: providing a convenient point of force application, and the anti-slip texture design increases friction during operation, making the winding and unwinding of the enclosure belt easier.

[0012] Preferably, the enclosure tape is a nylon webbing, and a plurality of reflective sheets are fixedly connected to the surface of the enclosure tape.

[0013] The effects achieved by the above components are: the nylon webbing is lightweight, flexible and strong, and easy to roll up and unroll; the reflective sheet significantly improves the visibility of the fence in low light environments, enhancing the warning effect and safety.

[0014] Preferably, the lower surfaces of the first support, the adjusting frame, and the second support are provided with an auxiliary structure. The auxiliary structure includes a plurality of bases, which are respectively fixedly connected to the first support, the adjusting frame, and the second support. The lower surface of the base is provided with an auxiliary groove, the inner wall of which is connected to a circular groove. A second spring is fixedly connected to the top side of the inner wall of the circular groove. The lower end of the second spring is fixedly connected to a base plate. The upper surface of the base plate is fixedly connected with two storage rods, and the arc surface of the storage rods is slidably connected to the base.

[0015] The aforementioned components achieve the following effects: providing deployable support legs, increasing the support area at the bottom of the support frame, enhancing the overall stability of the fence, and preventing tipping; the base plate can be folded up, reducing storage and transportation volume.

[0016] Preferably, the inner wall of the auxiliary groove is fixedly connected to two auxiliary rods, and the surface of the bottom plate is provided with a plurality of auxiliary rods, the inner diameter of which is adapted to the auxiliary rod.

[0017] The aforementioned components achieve the following effects: the auxiliary rod and auxiliary hole cooperate to guide and limit the base plate when it is unfolded and supported, ensuring that the base plate unfolds at the correct angle and is stably supported, and preventing the base plate from accidentally slipping or folding during use.

[0018] Compared with related technologies, the foldable safety fence provided by this utility model has the following beneficial effects:

[0019] This utility model provides a foldable safety fence. With an adjustable structure, it is easy to operate. Pulling the lever unlocks the connecting rod, and moving and rotating the connecting rod allows it to be stored, significantly reducing the transportation volume. After unlocking, the bracket can be moved and positioned freely. Combined with a unique gear linkage mechanism, turning a handle can simultaneously unroll and roll up two fence strips, achieving efficient and synchronous unfolding of the fence strips. This allows the fence to easily fit into curved or irregular areas for stable enclosure, overcoming the limitations of traditional straight-bar fences.

[0020] By incorporating an auxiliary structure, the base plate can be quickly unfolded by pulling it out, rotating it vertically, and then engaging it in an auxiliary slot with the aid of a spring. This significantly increases the support area at the bottom of the support frame, greatly enhancing its anti-overturning ability, making it particularly suitable for soft surfaces or environments subjected to lateral forces. The cooperation between the auxiliary rod and the auxiliary hole ensures a stable support angle for the unfolded base plate, preventing displacement. The operation is reversed when retracting, maintaining a compact overall structure for easy transportation and storage. Attached Figure Description

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please see Figures 1 to 6 The present invention provides a foldable safety fence, comprising: a first support 1, a second support 2, an adjustment structure 3, and an auxiliary structure 4. The upper end of the first support 1 is provided with the adjustment structure 3, and the lower surface of the first support 1, the adjustment frame 308, and the second support 2 is provided with the auxiliary structure 4.

[0031] In the embodiments of this utility model, please refer to Figures 1 to 5The adjusting structure 3 includes a connecting pipe 301 and two adjusting brackets 308. The connecting pipe 301 is rotatably connected to the first bracket 1. A connecting rod 302 is slidably connected to the inner wall of the connecting pipe 301. A fixing frame 303 is slidably connected to the lower end of the connecting rod 302. The fixing frame 303 is fixedly connected to the first bracket 1. Two positioning holes 304 are opened at the end of the connecting rod 302 away from the fixing frame 303. Two positioning rods 305 are slidably connected to the upper end of the second bracket 2. A lever 306 is fixedly connected to the arc surface of each positioning rod 305. A first spring 307 is sleeved on the arc surface of the positioning rod 305. Both ends are fixedly connected to the second bracket 2 and the lever plate 306, respectively. The diameter of the positioning rod 305 is adapted to the inner diameter of the positioning hole 304. The upper surfaces of the two adjusting frames 308 are fixedly connected to the cover frame 309. The upper surface of the cover frame 309 is fixedly connected to the connecting block 310. The inner wall size of the connecting block 310 is adapted to the connecting rod 302. The inner walls of the two adjusting frames 308 are rotatably connected to two rotating shafts 311. The arc surfaces of several rotating shafts 311 are fixedly connected to several enclosure belts 312. The enclosure belts 312 are grouped in groups of three. The movable ends of two groups of enclosures are fixedly connected to each other. The movable ends of the other two sets of fencing belts 312 are fixedly connected to the first support 1 and the second support 2, respectively. A second gear 315 is rotatably connected to the upper surface of the adjusting frame 308. The teeth of the second gear 315 mesh with two first gears 314. The first gears 314 are fixedly connected to the arc surface of the rotating shaft 311. The overall structure of the fence can be quickly folded and unfolded, and can adapt to the fencing needs of curved or irregular areas through the angle adjustment of the adjusting frame 308 and the linkage unwinding of the fencing belts 312. It is easy to operate and structurally stable. The connecting rod 302 is specifically a galvanized steel rod, and the connecting block 310 is specifically a galvanized steel block. The connecting block 310 is made of galvanized steel, which has the advantages of high strength, rust resistance, and long service life. The upper end of the rotating shaft 311 is fixedly connected to a handle. The arc surface of the handle has several anti-slip textures, providing a convenient force application point for operation. The anti-slip texture design increases the friction during operation, making the winding and unwinding operation of the fencing belt 312 easier. The fencing belt 312 is specifically made of nylon webbing. Several reflective sheets 313 are fixedly connected to the surface of the fencing belt 312. The nylon webbing is lightweight, flexible, and high-strength, making it easy to wind up and unwind. The reflective sheets 313 significantly improve the visibility of the fence in low-light environments, enhancing the warning effect and safety.

[0032] In the embodiments of this utility model, please refer to Figure 6The auxiliary structure 4 includes several bases 41, which are fixedly connected to the first support 1, the adjusting frame 308, and the second support 2, respectively. An auxiliary groove 42 is formed on the lower surface of each base 41. The inner wall of the auxiliary groove 42 is connected to a circular groove. A second spring 43 is fixedly connected to the top side of the inner wall of the circular groove. A base plate 44 is fixedly connected to the lower end of the second spring 43. Two storage rods 45 are fixedly connected to the upper surface of the base plate 44. The arc surfaces of the storage rods 45 are slidably connected to the base 41, providing expandable support feet. The large support area at the bottom of the frame enhances the overall stability of the fence and prevents it from tipping over. The base plate 44 is retractable, reducing storage and transportation volume. Two auxiliary rods 46 are fixedly connected to the inner wall of the auxiliary slot 42. Several auxiliary rods 46 are provided on the surface of the base plate 44. The inner diameter of the auxiliary rods 46 is adapted to the auxiliary rods 46. The auxiliary rods 46 cooperate with the auxiliary holes to guide and limit the base plate 44 when it is unfolded to ensure that the unfolding angle of the base plate 44 is correct and the support is stable, preventing the base plate 44 from accidentally slipping or folding during use.

[0033] The working principle of the foldable safety fence provided by this utility model is as follows: By setting the adjustment structure 3, the fence is unfolded. First, pull the two levers 306 and the positioning rods 305 in the direction away from each other. The first spring 307 is in a compressed state. At this time, the two positioning rods 305 slide away from the positioning holes 304 on the connecting rod 302, releasing the limitation on the connecting rod 302. The connecting rod 302 moves away from the second bracket 2. The connecting rod 302 moves along the inner wall of the connecting tube 301 and disengages from the two adjustment levers in sequence. The connecting block 310 on frame 308 is then operated to rotate the connecting pipe 301, causing the connecting pipe 301 and connecting rod 302 to rotate from a horizontal position downwards to a vertical position. Next, the connecting rod 302 is moved downwards, causing its lower end to slide into the inner wall of the fixed frame 303. At this point, the positions of the second bracket 2 and the two adjusting frames 308 can be moved to enclose the designated area. Then, the enclosure strip 312 on the adjusting frame 308 is fully unwound. One of the rotating shafts 311 on the adjusting frame 308 is rotated... While shaft 311 drives the enclosure belt 312 to unwind, shaft 311 also drives the first gear 314 to rotate. The first gear 314 transmits the rotational effect to the first gear 314 on another shaft 311 on the adjusting frame 308 through the second gear 315, causing the two shafts 311 on the adjusting frame 308 to rotate together and unwind the enclosure belt 312. After unwinding, the positions of the first support 1, the second support 2, and the two adjusting frames 308 are adjusted so that the enclosure belt 312 can be fully unfolded. The two supports 2 and the adjusting frame 308, together with the fencing belt 312, can fence off curved areas. The connecting rod 302 and the connecting block 310 are made of galvanized steel, which has the advantages of high strength, rust resistance and long service life. They provide easy-to-operate force application points. The anti-slip texture design increases the friction during operation, making the winding and unwinding operation of the fencing belt 312 easier. The nylon webbing is lightweight, flexible and strong, and easy to wind up and unwind. The reflective sheet 313 significantly improves the visibility of the fence in low light environments, enhancing the warning effect and safety.

[0034] By setting the auxiliary structure 4, the base plate 44 is first pulled away from the base 41. The second spring 43 always provides the base plate 44 with a spring force close to the base 41. After the base plate 44 drives the storage rod 45 to separate from the base 41, the base plate 44 can be rotated to be perpendicular to the base 41 and the angle of the base plate 44 is maintained. With the spring force of the second spring 43, the base plate 44 is slowly moved into the auxiliary groove 42. The base plate 44 and the base 41 are used for support to increase the support area. The auxiliary rod 46 cooperates with the auxiliary hole to guide and limit the base plate 44 when it is unfolded to ensure that the unfolding angle of the base plate 44 is correct and the support is stable, and to prevent the base plate 44 from accidentally sliding or folding during use.

[0035] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
