Description

Technical Field

[0001] This utility model relates to the field of protective roll netting technology, and in particular to a protective roll netting. Background Technology

[0002] Protective roll netting is a type of protective material or device that is easy to roll up and can be quickly unfolded. Common materials include fiber, plastic and metal. It is mainly used to achieve physical isolation, blocking, protection and warning functions. It is widely used in emergency rescue, engineering construction and other scenarios. However, its existing problems are prominent. First, the structural stability is not good. Traditional roll netting is prone to deformation or even breakage when subjected to high loads. These defects seriously restrict the use effect and application scope of protective roll netting. Second, the mesh design is relatively simple and the pores are too large, making it difficult to effectively block small objects such as gravel. Utility Model Content

[0003] The main purpose of this utility model is to provide a protective roll net that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A protective roll net includes two reinforcing plates. The upper front and upper rear ends of the two reinforcing plates are threaded with tapered nails. Two threaded posts are fixedly connected to the upper ends of the two reinforcing plates on their adjacent sides. A multi-layer composite mesh structure and a surface buffer assembly are sleeved on the upper outer surface of the four threaded posts from bottom to top. Nuts are threaded to the upper outer surface of the four threaded posts. A bottom reinforcing rib assembly is provided on the lower part of the two reinforcing plates on their adjacent sides.

[0006] Preferably, the bottom reinforcing rib assembly includes ten mounting frames. One end of each of the ten mounting frames is fixedly connected to the reinforcing plate. A hook is fixedly connected to the middle of the upper end of each of the ten mounting frames. A reinforcing rib mesh is hung on the outer surface of each of the ten hooks.

[0007] By adopting the above technical solution: the mounting frame is connected to the reinforcing plate to provide support, and the hook is used to hang the reinforcing mesh. The three work together to enhance the structural strength of the bottom of the roll mesh, distribute the force, prevent deformation and breakage under high load, and improve the overall stability. It is suitable for scenarios that are subjected to large external forces.

[0008] Preferably, the multi-layer composite mesh structure includes large-hole reinforced roll mesh, medium-hole reinforced roll mesh and fine-hole reinforced roll mesh, and two ring blocks are fixedly connected to the left and right ends of the large-hole reinforced roll mesh, medium-hole reinforced roll mesh and fine-hole reinforced roll mesh.

[0009] By adopting the above technical solution, the reinforced wire mesh with large, medium and small holes is connected to the threaded column by ring blocks. The layered combination can block objects of different sizes. The large holes are for ventilation, and the small holes are for blocking small objects, which can meet diverse protection needs and improve the accuracy and comprehensiveness of protection.

[0010] Preferably, the large-hole reinforcing mesh is located above the reinforcing rib mesh, the large-hole reinforcing mesh is located below the medium-hole reinforcing mesh, and the medium-hole reinforcing mesh is located below the fine-hole reinforcing mesh.

[0011] By adopting the above technical solution, the upper and lower positions of each layer of mesh are clearly defined, so that the large-mesh mesh first blocks large objects, the medium-mesh mesh further filters, and the fine-mesh mesh intercepts small objects, forming an orderly protection system and optimizing the protection effect and layers.

[0012] Preferably, the large-hole reinforced wire mesh, the medium-hole reinforced wire mesh, and the fine-hole reinforced wire mesh are respectively connected to the four threaded columns through four ring blocks.

[0013] By adopting the above technical solution, the ring block and the threaded post are movably connected, which facilitates the rapid installation, disassembly and adjustment of the multi-layer mesh, enhances the flexibility of use, and ensures a stable connection, so as to meet the needs of rapid deployment and replacement of protective mesh in different scenarios.

[0014] Preferably, the surface buffer assembly includes an upper buffer rope mesh layer, and connecting blocks are fixedly connected to the left and right ends of the upper buffer rope mesh layer. Each of the four connecting blocks has a through connecting hole at the middle of its upper end.

[0015] By adopting the above technical solution, the upper buffer rope net layer is connected to the threaded column through the connecting block and connecting hole, and is located above the fine mesh. It can buffer the impact of external forces, reduce the direct force on the net body, reduce the risk of damage, extend the service life of the roll net, and improve the protection safety.

[0016] Preferably, the upper buffer rope mesh layer is located above the fine-pore reinforced roll mesh, and the upper buffer rope mesh layer is movably connected to four threaded posts through four connecting blocks, with the four connecting blocks located on the lower side of the four nuts respectively.

[0017] By adopting the above technical solutions, the location and connection method of the buffer rope net layer are clearly defined to ensure that it can effectively buffer when under force, and the nuts are fixed to ensure its stable function, thereby enhancing the overall impact resistance of the roll net and ensuring the reliability of protection.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this utility model, the support and stability of the bottom of the roll net are enhanced by the installation frame, hooks and reinforcing mesh. The ten installation frames are connected to the reinforcing plate to provide a stable foundation for the structure. The hooks on them hang the reinforcing mesh to form a bottom support network, which can effectively disperse high load pressure and avoid deformation or breakage of the roll net due to excessive local stress. The upper buffer rope mesh layer is installed on the fine-mesh reinforced roll net, which can buffer the impact of objects, reduce the direct stress on the fine-mesh mesh and reduce the risk of damage. The two work together to significantly improve the overall structural strength and impact resistance of the protective roll net from the aspects of bottom support and surface buffer, and broaden its application range in high-load scenarios.

[0020] 2. In this utility model, the multi-layer composite mesh structure is composed of large, medium, and fine-hole reinforced roll mesh, forming a graded protection system. The large-hole roll mesh can initially intercept large objects, the medium-hole roll mesh further filters medium-sized objects, and the fine-hole roll mesh can effectively block small objects such as gravel. This solves the problem of traditional roll mesh having a single mesh size and being unable to protect small objects. The sleeve design of the ring block and the threaded column facilitates the installation and disassembly of each layer of mesh, improving the flexibility of use. The upper buffer rope net layer of the surface buffer component is installed on the fine-hole reinforced roll mesh, which can buffer the impact of external forces, reduce the direct force on the fine-hole mesh, avoid damage, and at the same time assist in intercepting missed objects, further improving the protective effect and reliability.

[0030] Please see Figure 1-5 This utility model provides a technical solution:

[0031] A protective mesh includes two reinforcing plates 1. The upper front and upper rear ends of the two reinforcing plates 1 are threadedly connected with tapered nails 2. The upper ends of the two reinforcing plates 1 on the side that is close to each other are fixedly connected with two threaded posts 3. The upper outer surface of the four threaded posts 3 is fitted with a multi-layer composite mesh structure 5 and a surface buffer assembly 6 from bottom to top. The upper outer surface of the four threaded posts 3 is threadedly connected with nuts 4. The lower ends of the two reinforcing plates 1 on the side that is close to each other are jointly provided with a bottom reinforcing rib assembly 7.

[0032] In this embodiment, the bottom reinforcing rib assembly 7 includes mounting frames 71, and ten mounting frames 71 are provided. One end of each of the ten mounting frames 71 is fixedly connected to the reinforcing plate 1. Hooks 72 are fixedly connected to the upper middle part of each of the ten mounting frames 71. Reinforcing rib mesh 73 is hung on the outer surface of each of the ten hooks 72. The upper buffer rope mesh layer 61 is located above the fine-hole reinforcing roll mesh 53. The upper buffer rope mesh layer 61 is movably connected to four threaded posts 3 through four connecting blocks 62. The four connecting blocks 62 are respectively located on the lower side of the four nuts 4.

[0033] Through the above scheme: In the bottom reinforcing rib assembly 7, ten mounting frames 71 are connected to the reinforcing plate 1 to provide basic support for the whole. The hooks 72 at the upper end are used to hang the reinforcing rib mesh 73 to form a bottom support network, which disperses the high load pressure and avoids deformation caused by excessive local stress. The upper buffer rope mesh layer 61 is sleeved on the threaded column 3 through the connecting block 62 and fixed above the fine hole reinforcing roll mesh 53 by the nut 4. When subjected to external impact, the buffer rope mesh layer can absorb part of the impact force, reduce the direct force on the fine hole reinforcing roll mesh 53, and prevent breakage. The combination of the two enhances the structural stability from the aspects of bottom support and surface buffer, and improves the use effect and application range of the roll mesh in high load scenarios.

[0034] In this embodiment, the multi-layer composite mesh structure 5 includes a large-hole reinforced mesh 51, a medium-hole reinforced mesh 52, and a fine-hole reinforced mesh 53. The left and right ends of the large-hole reinforced mesh 51, the medium-hole reinforced mesh 52, and the fine-hole reinforced mesh 53 are all fixedly connected to two ring blocks 54. The large-hole reinforced mesh 51 is located above the reinforcing mesh 73, the large-hole reinforced mesh 51 is located below the medium-hole reinforced mesh 52, and the medium-hole reinforced mesh 52 is located below the fine-hole reinforced mesh 53. The large-hole reinforced mesh 51, the medium-hole reinforced mesh 52, and the fine-hole reinforced mesh 53 are respectively connected to four threaded posts 3 through four ring blocks 54. The surface buffer assembly 6 includes an upper buffer rope mesh layer 61. The left and right ends of the upper buffer rope mesh layer 61 are fixedly connected to connecting blocks 62. The upper middle part of the four connecting blocks 62 is provided with a through connecting hole 63.

[0035] Through the above scheme, the multi-layer composite mesh consists of large-hole reinforced roll mesh 51, medium-hole reinforced roll mesh 52, and fine-hole reinforced roll mesh 53, which are fitted onto the threaded post 3 by ring blocks 54, forming a gradient protection layer. The large-hole mesh initially intercepts large objects, the medium-hole mesh further filters medium-sized objects, and the fine-hole mesh blocks small objects such as gravel, achieving precise graded protection. The upper buffer rope mesh layer 61 on the surface is connected to the threaded post 3 via connecting block 62 and is located above the fine-hole mesh. It can not only buffer the impact of objects and prevent the fine-hole mesh from breaking due to excessive force, but also help intercept missed objects. The combination of the two makes up for the shortcomings of a single mesh, improves the blocking effect on objects of different sizes, and broadens the protection application scenarios.

[0036] It should be noted that this utility model is a protective roll net. In use, the protective roll net first achieves efficient protection through the coordinated work of multiple components. The reinforcing plate 1 is fixed to the ground by the conical nail 2, providing a stable foundation for the whole. The threaded column 3 and the nut 4 cooperate to fix the multi-layer composite mesh structure 5 and the surface buffer component 6 in an orderly manner. In the bottom reinforcing rib component 7, the mounting frame 71 connects to the reinforcing plate 1, and the hook 72 hangs the reinforcing rib mesh 73 to enhance the bottom support force, distribute the force and prevent deformation. The multi-layer composite mesh is arranged from bottom to top in the form of large-hole reinforcing roll net 51, medium-hole reinforcing roll net 52 and fine-hole reinforcing roll net 53, and is secured by ring blocks 54. Connected to the threaded post 3, a graded protection system is formed: large-pore mesh intercepts large objects, medium-pore mesh filters medium-sized objects, and fine-pore mesh blocks small objects such as gravel. The upper buffer rope mesh layer 61 of the surface buffer component 6 is connected to the threaded post 3 through connecting block 62 and connecting hole 63, located above the fine-pore mesh, buffering impact and assisting in intercepting any missed objects. The components work together to solve the problem of traditional rolled mesh having excessively large pores and being unable to block small objects, while also improving structural stability and effectively resisting high-load external forces. Through gradient protection and structural reinforcement, the rolled mesh significantly improves its protective effect and applicability, making it suitable for various scenarios requiring efficient physical isolation. The above shows and describes the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed. The scope of protection of this utility model is defined by the appended claims and their equivalents.
