Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an adjustable connector and a prefabricated fence. Background Technology

[0002] In environments such as construction sites, public facilities, and temporary event spaces, fencing is a common protective facility with extremely high demand. Traditional fencing mostly adopts a fixed structure, usually made of metal or wood, and is fixed by welding or bolts. However, this traditional fencing has many shortcomings: First, the installation and dismantling process is cumbersome, time-consuming, and labor-intensive; second, the fixed structure lacks flexibility and cannot be quickly adjusted according to actual needs; third, it results in significant material waste and is difficult to reuse, which does not conform to modern environmental protection concepts.

[0003] To address the aforementioned issues, existing fencing options include modular adjustable fencing, which is primarily composed of multiple standardized modular units connected via plug-in joints for easy and quick installation and disassembly. Another type of existing fencing features an adaptive adjustment mechanism, which utilizes a spring and sliding rail system to automatically adjust the fencing's height and angle within a certain range. While these patents improve the flexibility and convenience of fencing to some extent, they still have some shortcomings. For example, the modular fencing lacks sufficient connection flexibility, making it inconvenient for on-site use; the adaptive adjustment mechanism is complex and has high maintenance costs. Utility Model Content

[0004] This invention provides an adjustable connector and a prefabricated fence, which overcomes the shortcomings of the prior art.

[0005] According to the present invention, an adjustable connector includes a connector body respectively disposed at both ends of a protective net. The connector body includes a vertically erected connecting rod, and the upper and lower ends of the connecting rod are provided with connecting sleeves that can rotate around the connecting rod.

[0006] This invention provides a convenient solution for fence installation. When installing a fence, installers can place multiple connector bodies at pre-set points, rotate the connecting sleeves to the appropriate positions, and then install the protective netting between the connector bodies. This process is repeated until all protective netting is installed, completing the protection. The connecting sleeves can rotate around the connecting vertical rods, making the connection between fences more flexible and allowing for adjustments to the fence's shape and size according to actual needs. The connector bodies are simple in design and easy to operate, requiring no complex tools or steps during fence installation, greatly improving construction efficiency. The connector bodies are also designed for easy inspection and maintenance; if a connection part is worn or damaged, it can be quickly located and replaced without replacing the entire fence system. The standardized interface design between the connecting sleeves and the protective netting allows for rapid assembly and disassembly of the netting. It offers high flexibility for installation locations of different sizes and shapes, allowing the connecting sleeves to be rotated according to the actual conditions of the adjacent edges to ensure optimal protection. Furthermore, since the components do not require welding and can be reused, material waste and welding pollution are reduced, offering economic and environmental advantages.

[0007] Preferably, the connecting vertical rod is provided with a plurality of fixing nuts for fixing the position of the connecting sleeve. The fixing nuts are located at the upper and lower ends of the connecting sleeve and clamp the connecting sleeve. The two ends of the connecting vertical rod are provided with external threads that are threaded to the fixing nuts.

[0008] This invention allows for adjustment of the height of the protective netting to a certain extent through the design of the fixing nut and external thread. In situations where the protective height needs to be increased or there are obstacles on the ground, the height of the protective netting can be raised by adjusting the fixing nut. The fixing nut and the external thread of the connecting vertical rod are tightly engaged, which can firmly lock the position of the connecting sleeve and prevent the vertical position of the connecting sleeve from moving due to vibration or external force during the use of the fence. The fixing nuts are located at the upper and lower ends of the connecting sleeve and clamp the connecting sleeve. This design can fix the horizontal position of the connecting sleeve, prevent it from rotating horizontally, facilitate the installation process, and increase its own strength.

[0009] Preferably, a square base steel plate is welded below the connecting vertical rod, and the base steel plate is provided with a fixing through hole, at which an expansion bolt for fixing the connecting body to the ground is provided.

[0010] This invention provides a larger contact area for the square base steel plate, effectively distributing the force on the connecting vertical bars and enhancing the overall stability of the fence. Expansion bolts securely fix the base steel plate to the ground through the fixing through holes, preventing the fence from tilting or shifting due to external forces. The design of the base steel plate and fixing through holes makes the installation of the connector body simpler and faster; the connector body can be fixed to the ground or foundation simply by using expansion bolts, and the installation of expansion bolts does not require complex tools or techniques, making it suitable for rapid on-site construction. The fixing method of the expansion bolts also allows the connector body to be easily disassembled and reinstalled, making it suitable for temporary fences or scenarios requiring frequent relocation.

[0011] Preferably, the connecting sleeve includes a first sleeve and a second sleeve. The first sleeve includes a first steel sleeve that is perpendicular to the connecting vertical rod and has a first connecting member at one end near the connecting vertical rod. The second sleeve includes a second steel sleeve that is perpendicular to the connecting vertical rod and has a second connecting member at one end near the connecting vertical rod.

[0012] With this invention, the first sleeve and the second sleeve are respectively set vertically to the connecting vertical rod and fixed by the first connector and the second connector to form a stable triangular support structure, which can effectively distribute the force and enhance the overall stability of the fence.

[0013] Preferably, both the first connector and the second connector are fitted onto the connecting vertical rod, with the second connector embedded inside the first connector in a cylindrical shape.

[0014] With this invention, the first and second connectors are fitted onto the connecting vertical rod and form a tight fit through the embedded design, which can effectively enhance the stability of the connection and prevent the fence from loosening due to vibration or external force during use. The cylindrical design makes the contact area between the first and second connectors and the connecting vertical rod larger, and the force is more evenly distributed, further improving the overall stability of the fence.

[0015] A prefabricated fence includes a protective net and an adjustable connector as described above.

[0016] This invention uses a standardized interface to connect the protective net and the connector. The interface size is pre-designed, which makes the installation and disassembly process simple and quick. This greatly shortens the construction time, improves construction efficiency, and helps to shorten the overall project cycle. At the same time, it can be reused after disassembly, which improves resource utilization efficiency.

[0017] Preferably, the protective net includes two parallel and horizontally arranged connecting crossbars, with a protective netting sheet connecting the two connecting crossbars between them.

[0018] This invention utilizes two parallel and horizontally arranged connecting crossbars to provide uniform support for the protective mesh, enhancing its overall stability. The connection method between the protective mesh and the connecting crossbars allows for even distribution of force when subjected to external forces, reducing localized stress concentration and improving impact resistance. The welded connection ensures the firmness of the joint, preventing the mesh from loosening or falling off due to vibration or external forces during use. The parallel arrangement of the two connecting crossbars further enhances the uniformity of the force distribution on the mesh, reinforcing the connection's strength.

[0019] Preferably, the two ends of the connecting crossbar are connected to a first steel sleeve and a second steel sleeve, respectively.

[0020] This invention employs a weld-free interface design, allowing installation to be completed simply by inserting both ends of the connecting crossbar into the first and second steel sleeves, respectively. This simplifies and speeds up the installation and disassembly process, lowers the barrier to entry, significantly reduces construction time, improves construction efficiency, and helps shorten the overall project cycle. Furthermore, it is interchangeable across different installation locations, further enhancing resource utilization efficiency. Attached Figure Description

[0028] In this embodiment, when installing a fence, the installer, facing installation locations of different sizes and shapes, places multiple connector bodies 100 at preset points, rotates the connecting sleeve 220 to the appropriate position, and then installs the protective netting 110 between the connector bodies 100. This step is repeated until all protective netting 110 is installed, completing the protection. The connecting sleeve 220 can rotate around the connecting vertical rod 210, making the connection between fences more flexible and facilitating adjustment of the fence's shape and size according to actual needs. The connector body 100 has a simple design and is easy to operate, requiring no complicated tools or steps during fence installation, greatly improving construction efficiency. The design of the connector body 100 facilitates inspection and maintenance. If a connection part is worn or damaged, it can be quickly located and replaced without replacing the entire fence system. The standardized interface design between the connecting sleeve 220 and the protective net 110 allows for the rapid assembly and disassembly of the protective net 110. It offers high flexibility for installation locations of different sizes and shapes, allowing the connecting sleeve 220 to be rotated according to the actual conditions of the adjacent edge of the installation location to ensure optimal protection. Furthermore, since its components do not require welding and can be recycled, it reduces material waste and welding pollution, offering economic and environmental advantages.

[0029] In this embodiment, the connecting vertical rod 210 is provided with a plurality of fixing nuts 310 for fixing the position of the connecting sleeve 220.

[0030] In this embodiment, the design of the fixing nut 310 and the external thread allows for adjustment of the height of the protective net 110 to a certain extent. In situations where the protective height needs to be increased or there are obstacles on the ground, the height of the protective net 110 can be raised by adjusting the fixing nut 310. The fixing nut 310 and the external thread of the connecting vertical rod 210 are tightly engaged, which can firmly lock the position of the connecting sleeve 220 and prevent the vertical position of the connecting sleeve 220 from moving due to vibration or external force during the use of the fence. The fixing nuts 310 are located at the upper and lower ends of the connecting sleeve 220 and clamp the connecting sleeve 220. This design can fix the horizontal position of the connecting sleeve 220, prevent it from rotating horizontally, facilitate the installation process, and increase its own strength.

[0031] In this embodiment, a square base steel plate 230 is welded below the connecting vertical rod 210. The base steel plate 230 is provided with a fixing through hole 240, and an expansion bolt 250 for fixing the connecting body 100 to the ground is provided at the fixing through hole 240.

[0032] In this embodiment, the square base steel plate 230 provides a larger contact area, which can effectively distribute the force on the connecting vertical rod 210 and enhance the overall stability of the fence. The expansion bolts 250 firmly fix the base steel plate 230 to the ground through the fixing through holes 240, preventing the fence from tilting or shifting due to external forces. The design of the base steel plate 230 and the fixing through holes 240 makes the installation of the connector body 100 simpler and faster. The connector body 100 can be fixed to the ground or foundation simply by using the expansion bolts 250, and the installation of the expansion bolts 250 does not require complicated tools or techniques, making it suitable for rapid on-site construction. The fixing method of the expansion bolts 250 also makes it easy to disassemble and reinstall the connector body 100, which is suitable for temporary fences or scenarios that require frequent relocation.

[0033] In this embodiment, the connecting sleeve 220 includes a first sleeve 320 and a second sleeve 330. The first sleeve 320 includes a first steel sleeve 321 that is perpendicular to the connecting vertical rod 210. The first steel sleeve 321 has a first connector 322 at one end near the connecting vertical rod 210. The second sleeve 330 includes a second steel sleeve 331 that is perpendicular to the connecting vertical rod 210. The first steel sleeve 321 has a second connector 332 at one end near the connecting vertical rod 210.

[0034] In this embodiment, the first sleeve 320 and the second sleeve 330 are respectively perpendicular to the connecting vertical rod 210 and fixed by the first connector 322 and the second connector 332 to form a stable triangular support structure, which can effectively distribute the force and enhance the overall stability of the fence.

[0035] In this embodiment, both the first connector 322 and the second connector 332 are sleeved on the connecting vertical rod 210, and the second connector 332 is embedded in the first connector 322 in a cylindrical shape.

[0036] In this embodiment, the first connector 322 and the second connector 332 are fitted onto the connecting vertical rod 210 and form a tight fit through the embedded design, which can effectively enhance the stability of the connection part and prevent the fence from loosening due to vibration or external force during use. The cylindrical design makes the contact area between the first connector 322 and the second connector 332 and the connecting vertical rod 210 larger, and the force is more even, which further improves the overall stability of the fence.

[0037] A prefabricated fence includes a protective net 110 and an adjustable connector as described above.

[0038] In this embodiment, the protective net 110 and the connector are connected by a standardized interface. The interface size is pre-designed, which makes the installation and disassembly process simple and quick. This greatly shortens the construction time, improves the construction efficiency, and helps to shorten the overall project cycle. At the same time, it can be reused after disassembly, which improves the efficiency of resource utilization.

[0039] In this embodiment, the protective net 110 includes two parallel and horizontally arranged connecting crossbars 120, and a protective net sheet 130 connecting the two connecting crossbars 120 is provided between the two connecting crossbars 120.

[0040] In this embodiment, the two connecting crossbars 120 are arranged parallel and horizontally, which can provide uniform support for the protective mesh 130 and enhance the overall stability of the protective mesh 110. The connection method between the protective mesh 130 and the connecting crossbars 120 allows the protective mesh 110 to distribute the force evenly when subjected to external forces, reducing local stress concentration and improving impact resistance. The connection method between the protective mesh 130 and the connecting crossbars 120 is welding, which can ensure the firmness of the connection and prevent the protective mesh 110 from loosening or falling off due to vibration or external forces during use. The parallel arrangement of the two connecting crossbars 120 makes the force on the protective mesh 130 more uniform, further enhancing the firmness of the connection.

[0041] In this embodiment, the two ends of the connecting crossbar 120 are respectively connected to the first steel sleeve 321 and the second steel sleeve 331.
