Description

Technical Field

[0001] This utility model belongs to the field of fence technology, and specifically relates to a quick-assembly and disassembly steel fence. Background Technology

[0002] Fences, as a common protective facility, are widely used in construction sites, public areas, private residences, and industrial sites. Their main functions are to provide security isolation, prevent unauthorized personnel from entering specific areas, protect privacy, and define boundaries. Fences not only act as physical barriers but also enhance security and prevent accidents.

[0003] However, most current fencing designs do not consider the specific needs of corners, resulting in fixed corner fences that cannot be adjusted according to actual needs. This fixed structure makes the fences very rigid and inflexible when encountering complex terrain or special layouts. Because the corner fences are fixed, it is usually necessary to build two separate fences to close the corner. This not only increases construction costs but also causes unnecessary waste of resources, and the duplicated fences occupy more space, affecting the utilization rate of the site.

[0004] In view of this, this application proposes a quick-assembly and disassembly steel fence to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a quick-assembly and disassembly steel fence. By designing the fence assembly, the sliding groove and sliding plate design enable the fence to be easily and quickly assembled and disassembled. When used at corners, it can be adjusted by rotation, making it suitable for use at corners. This effectively overcomes the problem of traditional fences being inconvenient to adjust at complex corners and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A quick-assembly and disassembly steel fence includes two sets of fence posts, with multiple railing assemblies between the two sets of fence posts. Each railing assembly includes an extension rod on one side of a fence post, a central frame on one side of the extension rod, a fixing block on one side of the central frame, a side rod fixedly connected to one side of the fixing block, and a set of sliding plates fixedly connected to one end of each side rod and one end of the extension rod. A sliding groove is provided on the side of the fence post closest to the railing assembly. Two sets of rotating plates are fixedly connected to one side of the central frame, each rotating plate having a rod hole at one end, a round rod inside the rod hole, and one end of the round rod fixedly connected to the fixing block. A limit groove is provided within the fixing block.

[0008] With the above technical solution, when the fence post closest to the extension rod is rotated, the extension rod will cause the central frame to rotate under its influence. The central frame, in turn, rotates the rod hole outside the round rod via a rotating plate, thereby achieving the turning adjustment of the extension rod and ensuring safe isolation of the fence at corners.

[0009] In a preferred embodiment, one side of the extension rod is located inside the rear of the central frame, and a set of guide grooves are provided on the upper and lower sides of the extension rod. An inner block is provided in the guide groove, and the inner block is fixedly connected to the central frame.

[0010] With the above technical solution, when the extension rod is pulled, the extension rod can drive the guide groove to move in a straight line along the path defined by the fixed inner block.

[0011] In a preferred embodiment, the diameter of the upper end of the round rod is greater than the diameter of the through hole, the two sets of rotating plates are located on the upper and lower sides of the fixed block respectively, and multiple sets of partition rods are installed in front of the interior of the central frame.

[0012] Through the above technical solution, the partition bar can block the gap in the middle of the central frame, making it difficult for debris outside the fence to enter the fence through the central frame.

[0013] In a preferred embodiment, both the sliding plate and the sliding groove have a T-shaped structure when viewed from above, and the sliding plate and the sliding groove are slidably connected. The fence posts, extension rods, and side rods are all made of steel.

[0014] With the above technical solution, when installing the fence, place the fence posts in the predetermined position, then pick up multiple sets of fence components, align the sliding plates on both sides of the side bars and extension bars with the sliding grooves on the fence posts, and push them into the sliding grooves from top to bottom to complete the rapid installation of multiple sets of fence components.

[0015] In a preferred embodiment, the position of the limiting groove corresponds to the position of the extension rod, the thickness of the extension rod is less than the thickness of the limiting groove, and a set of partition plates are fixedly connected to the lower side of the extension rod and the lower side of the side rod, respectively.

[0016] Through the above technical solution, the partition plate can contact the side bars and extension bars of the lower railing assembly, thereby creating gaps between multiple railing assemblies. When the wind blows, the airflow can pass through these gaps, effectively dispersing the impact of the wind on the overall fence.

[0017] As a preferred embodiment, each of the two sets of fence posts is provided with a set of support components below them. The support components include a fence base fixedly installed below the fence posts, and a rubber anti-slip pad is glued to the lower surface of the fence base.

[0018] Through the above technical solution, the rubber anti-slip mat has good friction, making it difficult for the fence base to slip when it comes into contact with the ground.

[0019] In a preferred embodiment, a support plate is provided above the fence base, and a set of through holes are respectively opened at the four corners of the fence base, with springs installed above the through holes.

[0020] With the above technical solution, a heavy object is placed on the support plate. As the weight of the object is applied, the support plate is pressed down, and the spring connected to it is then compressed.

[0021] In a preferred embodiment, a grounding rod is provided inside the through hole. The grounding rod is located inside the spring, and the lower end of the grounding rod is a pointed cone. The upper end of the spring and the upper end of the grounding rod are both fixedly connected to the bearing plate.

[0022] The above technical solution effectively anchors the fence base when the pointed tip of the ground-inserting pole is inserted into the soft ground. This prevents the fence base from sliding or shifting due to soft ground.

[0023] After adopting the above technical solution, the beneficial effects of this utility model are:

[0024] 1. By designing the railing assembly, the sliding groove and sliding plate design enable the fence to be easily and quickly assembled and disassembled. When used at corners, the railing assembly can be adjusted by rotation, making it suitable for use at corners. This effectively overcomes the problem of traditional railings being inconvenient to adjust at complex corners. Furthermore, during normal use, by inserting the extension rod into the limiting groove, the railing assembly can be prevented from rotating, thus allowing for quick adjustment of the usage method according to straight passages and corner areas.

[0025] 2. By designing support components, the fence base can support the fence when used on flat ground. When used on soft ground, by placing a weight on the support plate, the weight of the weight presses down on the support plate, and the connected ground stake will naturally insert into the soft ground. This additional pressure from the weight allows the ground stake to be anchored into the soft soil, preventing the fence base from sliding or shifting due to soft ground. Attached Figure Description

[0034] 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.

[0035] Please see Figures 1 to 6A quick-assembly and disassembly steel fence includes two sets of fence posts 1, with multiple sets of railing assemblies 2 between the two sets of fence posts 1; the railing assembly 2 includes an extension rod 21 on one side of the fence post 1, a central frame 22 on one side of the extension rod 21, a fixing block 26 on one side of the central frame 22, a side rod 23 fixedly connected to one side of the fixing block 26, a set of sliding plates 24 fixedly connected to one end of the side rod 23 and one end of the extension rod 21 respectively, and a sliding groove 213 is opened on the side of the fence post 1 near the railing assembly 2; two sets of rotating plates 27 are fixedly connected to one side of the central frame 22, a rod hole is opened at one end of the rotating plate 27, a round rod 28 is provided in the rod hole, one end of the round rod 28 is fixedly connected to the fixing block 26, and a limit groove 29 is opened in the fixing block 26.

[0036] When the fence post 1 closest to the extension rod 21 is rotated, the extension rod 21 will cause the center frame 22 to rotate. The center frame 22, in turn, rotates the rod hole outside the round rod 28 via the rotating plate 27, thereby achieving the turning adjustment of the extension rod 21 and ensuring safe isolation of the fence at the corner.

[0037] One side of the extension rod 21 is located inside the rear of the center frame 22. A set of guide grooves 210 are provided on the upper and lower sides of the extension rod 21. An inner block 211 is provided in the guide groove 210 and is fixedly connected to the center frame 22.

[0038] When the extension rod 21 is pulled, the extension rod 21 can drive the guide groove 210 to move in a straight line along the path defined by the fixed inner block 211.

[0039] The diameter of the upper end of the round rod 28 is greater than the diameter of the through hole 33. The two sets of rotating plates 27 are located on the upper and lower sides of the fixed block 26, respectively. Multiple sets of partition rods 212 are installed in the front of the interior of the center frame 22.

[0040] The partition bar 212 can block the gap in the middle of the central frame 22, making it difficult for debris outside the fence to enter the fence through the central frame 22.

[0041] The sliding plate 24 and the sliding groove 213 are both T-shaped structures when viewed from above. The sliding plate 24 and the sliding groove 213 are slidably connected. The fence uprights 1, extension rods 21 and side rods 23 are all made of steel.

[0042] When installing the fence, place the fence post 1 in the designated position, then pick up multiple sets of fence components 2, align the sliding plates 24 on both sides of the side bar 23 and the extension bar 21 with the sliding grooves 213 on the fence post 1, and push them into the sliding grooves 213 from top to bottom to complete the quick installation of multiple sets of fence components 2.

[0043] The position of the limiting groove 29 corresponds to the position of the extension rod 21. The thickness of the extension rod 21 is less than the thickness of the limiting groove 29. A set of partition plates 25 are fixedly connected to the lower side of the extension rod 21 and the lower side of the side rod 23, respectively.

[0044] The partition plate 25 can contact the side bar 23 and extension bar 21 at the lower railing assembly 2, thereby creating gaps between multiple railing assemblies 2. When the wind blows, the airflow can pass through these gaps, effectively dispersing the impact of the wind on the entire fence.

[0045] Each of the two sets of fence posts 1 has a set of support components 3 below it. The support components 3 include a fence base 32 fixedly installed below the fence post 1. The lower surface of the fence base 32 is glued with a rubber anti-slip pad.

[0046] The rubber anti-slip mat has good friction, making it difficult for the fence base 32 to slip when it comes into contact with the ground.

[0047] A support plate 31 is provided above the fence base 32, and a set of through holes 33 are respectively opened at the four corners of the fence base 32, and a spring 34 is installed above the through hole 33.

[0048] When a heavy object is placed on the support plate 31, the support plate 31 is pressed down by the weight of the object, and the spring 34 connected to it is compressed.

[0049] A grounding rod 35 is provided in the through hole 33. The grounding rod 35 is located inside the spring 34. The lower end of the grounding rod 35 is a pointed cone. The upper end of the spring 34 and the upper end of the grounding rod 35 are both fixedly connected to the bearing plate 31.

[0050] When the pointed tip of the ground anchor 35 is inserted into the soft ground, it effectively anchors the fence base 32, preventing the fence base 32 from sliding or shifting due to soft ground.

[0051] In practical use, the working principle of this utility model is as follows:

[0052] During fence installation, place the fence posts 1 in the designated location. Then, pick up multiple sets of railing components 2, aligning the sliding plates 24 on both sides of the side bars 23 and extension bars 21 with the sliding grooves 213 on the fence posts 1, and push them into the sliding grooves 213 from top to bottom to complete the quick installation of the multiple sets of railing components 2. When disassembly is required, slide the multiple sets of railing components 2 out of the sliding grooves 213 in the reverse order of installation to quickly complete the disassembly. During the installation process of the railing components 2, the upper... The partition plate 25 at the square railing assembly 2 contacts the side bar 23 and extension bar 21 at the lower railing assembly 2, thereby creating gaps between multiple railing assemblies 2. When the wind blows, the airflow can pass through these gaps, effectively dispersing the impact of the wind on the overall fence and preventing the fence from tipping over due to the wind. When encountering a corner area, pulling the fence post 1 on the side closest to the extension bar 21 causes the fence post 1 to move synchronously with the extension bar 21 connected to it, so that the front end of the extension bar 21 disengages from the limiting groove 29. During this process, the extension bar 21 drives the guide groove 210 to move in a straight line along the path defined by the fixed inner block 211. Then, rotating the fence post 1 on this side will cause the extension bar 21 to rotate the center frame 22 under its influence. The center frame 22 drives the rod hole to rotate outside the round rod 28 through the rotating plate 27, thereby realizing the turning adjustment of the extension rod 21 and realizing the safety isolation of the fence at the corner. In the conventional use scenario of straight road, the extension rod 21 is pushed to insert it into the limiting groove 29. The limiting groove 29 can limit the extension rod 21, making it difficult for it to rotate, which is effective for straight road sections.

[0053] When the fence is deployed on a flat and solid road surface, the fence base 32 supports the fence posts 1, ensuring that the fence posts 1 stand vertically. When deployed on a soft road surface, a heavy object (such as a stone) is placed on the support plate 31. As the weight of the object is applied, the support plate 31 is pressed down, and the spring 34 connected to it is compressed. At the same time, the support plate 31 drives the ground insertion rod 35 to descend steadily within the through hole 33 until the lower pointed end of the ground insertion rod 35 inserts into the soft road surface, thus effectively anchoring the fence base 32. This prevents the fence base 32 from sliding or shifting due to soft ground. Furthermore, when the fence needs to be dismantled, the heavy object can be removed from the support plate 31. At this time, the spring 34 rebounds, causing the support plate 31 to rise, which in turn drives the ground insertion rod 35 into the through hole 33, thereby quickly contacting and anchoring it, facilitating subsequent dismantling of the fence.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
