Description

Technical Field

[0001] This utility model relates to the field of sports facilities technology, and in particular to a splicing net structure for large venues. Background Technology

[0002] In the operation and use of large public venues such as stadiums, convention centers, and large theaters, it is often necessary to set up netting structures according to actual needs to achieve functions such as event protection, equipment hanging, zoning isolation, and decoration. For example, when holding events in basketball courts, protective netting needs to be installed around or above the court to prevent sports equipment or personnel from accidentally falling; when holding large exhibitions in convention centers, netting is needed to hang promotional slogans, lighting equipment, or display props to optimize space utilization efficiency and visual presentation.

[0003] However, most of the suspended netting structures currently used in large venues adopt an integral design or a simple splicing design, which has many technical defects and limitations in use. On the one hand, integral suspended netting structures face significant challenges in production, transportation, and installation: due to the large size of large venues, integral suspended netting is usually large in volume and weight, which not only increases the complexity of molds and processes during factory production, but also places extremely high demands on the load-bearing equipment and route planning during transportation, making it highly susceptible to structural deformation due to collisions and compression during transportation; during the on-site installation phase, integral suspended netting requires large hoisting equipment for overall hoisting, which is not only limited by the space height and load-bearing capacity of the venue's roof, but also requires precise adjustment of the netting position, resulting in low installation efficiency and high installation costs.

[0004] On the other hand, while existing simple splicing netting structures alleviate the transportation and installation difficulties of monolithic structures to some extent, they still have significant shortcomings in terms of structural stability, adaptability, and flexibility of use. These simple splicing structures often use external bolts to directly connect adjacent netting units, resulting in weak structural strength at the joints. Long-term use or exposure to heavy loads can easily lead to loosening and deformation, making it difficult to meet the safety and stability requirements of large venues for netting structures. Furthermore, external connection structures occupy extra space, affecting not only the overall aesthetics of the netting structure but also potentially interfering with personnel activities or the installation and use of other equipment within the venue.

[0005] Furthermore, most of the hanging components in existing suspended structures are fixed, making it impossible to flexibly adjust their positions according to actual usage needs. When it is necessary to suspend equipment or props of different positions or sizes, it is often necessary to disassemble and reinstall the suspended structure, which is cumbersome, time-consuming, and labor-intensive, greatly reducing the efficiency and adaptability of the suspended structure. Currently, there are no effective solutions to the problems existing in the production, transportation, installation, and operational stability and flexibility of the suspended structures for large venues. Therefore, existing technologies still need improvement and enhancement. Utility Model Content

[0029] This utility model provides a spliced ​​hanging net structure for large venues. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. In the description of this utility model, it should be understood that the terms "up, down, left, right," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] Please see Figures 1 to 6 This utility model provides a spliced ​​hanging net structure for large venues, including: several spliced ​​hanging units, each hanging unit including a hanging hook 1 and an integrally formed hanging body 2; the hanging body 2 includes an upper rail 3 and a lower rail 4 arranged in a balanced manner, the top of the upper rail 3 having a fixed slot 5 along the center line for fixing to the installation arm 6 suspended from the venue; wherein, the fixed slot 5 is a through slot.

[0031] A connecting piece 7 is disposed at the splicing point of two adjacent hanging bodies 2. Its two ends are fixed to the side walls of the upper rails 3 of the two hanging bodies 2 by bolts, and the connecting piece 7 is housed within the internal space of the upper rails 3. Specifically, the connecting piece 7 is a metal strip whose width and shape are perfectly suited to fit into the internal cavity of the upper rails 3, forming a locking and fixing mechanism within the rails. During splicing, the connecting piece 7 is inserted into the end of the upper rails 3 of the two adjacent hanging units, and bolts are screwed into the pre-drilled holes on the side walls of the rails, penetrating into the rails and fastening to the threaded holes at both ends of the connecting piece 7. This completes a concealed and secure connection within the rails, and can form a seamless splice if necessary.

[0032] Preferably, the connecting piece 7 is fixedly installed on both side walls of the upper track 3. That is, at each joint of the upper track 3 that needs to be spliced, a connecting piece 7 as described above is symmetrically installed on the left and right side walls.

[0033] In this embodiment, the hook 1 is slidably mounted on the lower track 4 and includes a hanging shaft 8, a hanging ring 9, and rollers 10 at both ends of the hanging shaft 8. The rollers 10 bear the load on the surface of the lower track 4, and the hanging shaft 8 is hinged to the hanging ring 9 via a rotating pin 11. Specifically, the hanging shaft 8 is a solid round steel bar, and the rollers 10 at both ends are made of nylon or metal wheels with ball bearings to ensure smooth rolling on the surface of the lower track 4. The hanging ring 9 is connected to the middle of the hanging shaft 8 via a rotating pin 11 perpendicular to the hanging shaft 8. The bottom end of the hanging pin is fixed with a cotter pin or snap ring, allowing the hanging ring 9 to rotate freely around the axis of the rotating pin 11 to accommodate hanging loads in different directions.

[0034] The hook 1 also includes a spring clip 12, which is detachably fastened to the hanging ring 9 for hooking and suspending the protective net. The spring clip 12 is a U-shaped or C-shaped component made of spring steel wire. Its two ends at the open end have small inward-facing hooks. Optionally, the hanging ring 9 has corresponding grooves or through holes designed to mate with the hooks. During installation, the opening of the spring clip 12 is forcefully opened, allowing it to pass over the hanging ring 9. The elasticity of the material itself causes the hooks at the ends to engage with the grooves in the hanging ring 9, achieving quick fastening and locking, preventing it from coming loose under vibration; or the spring clip 12 can be directly fastened to the hanging ring 9 for connecting the protective net.

[0035] An upper washer 13 and a lower washer 14 are clamped and fixed on the inner and outer sides of the fixing slot 5, respectively. The upper washer 13 is fixed to the end of the mounting arm 6, and the lower washer 14 abuts against the inner wall of the hanging body 2. The clamping and fixing are achieved by bolts passing through the fixing slot 5. It can be understood that the lower washer 14 is first lifted upwards from inside the hanging body 2, making it fit tightly against the inner edge of the fixing slot 5. Then, the upper washer 13 on the end of the stadium mounting arm 6 is aligned with the fixing slot 5. Next, a long bolt is passed through the upper washer 13, the fixing slot 5, and the lower washer 14 in sequence, and finally tightened inside the hanging body 2. The clamping force of the bolt compresses the entire connection point into a single unit.

[0036] To enhance the connection strength, a fastening groove 15 is provided on the top of the lower gasket 14, and the edge of the fixing slot 5 extends downward to form a fastening flange 16. The fastening flange 16 is engaged in the fastening groove 15 to enhance connection stability. The operator can align the flange by hand and press it into the fastening groove 15. This mating structure provides initial positioning and anti-slip function before the bolt is tightened. After the bolt is tightened, the tight fit between the flange and the groove wall effectively resists shearing forces.

[0037] In this embodiment, the upper gasket 13, lower gasket 14, and connecting piece 7 can adopt a uniform specification to facilitate interchangeability during production and maintenance. This not only reduces manufacturing costs but also improves assembly efficiency, as operators do not need to distinguish between gaskets or connecting pieces of different specifications. Furthermore, components of uniform specifications can reduce the risk of connection failure due to misassembly in actual use, further enhancing the reliability of the overall structure.

[0038] The bottom of the hanging body 2 has symmetrically embedded grooves 17 along its length, and LED light groups 18 are embedded in these grooves 17. During the extrusion molding of the hanging body 2, these inwardly recessed grooves 17 are pre-formed on both sides of its bottom. The LED light groups 18 are flexible LED strips with adhesive backing. During installation, simply remove the protective film and directly attach the LED strips into the embedded grooves 17. The power supply line can be introduced into the internal space of the track from the end of the hanging body 2 or through a specific interface, achieving concealed wiring. A transparent PC material light shield or diffuser can optionally be installed at the opening of the groove to make the light softer and more aesthetically pleasing.

[0039] Please see Figure 2 The system also includes an end-face sealing plate 19, which is fixed to the end-face opening on the front or rear side of the hanging body 2 by screws. The end-face sealing plate 19 is a plastic or metal plate with a shape consistent with the end face contour of the hanging body 2. It has several mounting through holes around its perimeter. Threaded holes are pre-drilled at corresponding positions on the end face of the hanging body 2. During installation, the end-face sealing plate 19 is aligned with the end-face opening, and self-tapping screws or machine screws are passed through the mounting through holes and screwed into the threaded holes on the end face of the body to seal the end face, forming a neat and dustproof end.

[0040] The suspended main body 2 can be straight, curved, or a combination thereof. It is understood that on the construction site, based on the actual shape of the stadium roof, the straight and curved sections of the suspended main body 2 are combined and spliced ​​together using connecting pieces 7 to form any desired planar or spatial curved network.

[0041] In summary, the modular hanging mesh structure for large venues of this utility model, by employing several modular hanging units, can flexibly adapt to the spatial dimensions and shapes of different large venues. Whether it is a vast space in a large venue or an area with an irregular shape, it can be quickly spliced ​​and adjusted according to actual needs, which greatly improves the applicability and versatility of the hanging mesh structure and solves the problem that traditional integral hanging mesh structures are difficult to adapt to diverse venue spaces.

[0042] Secondly, the upper rail 3 and lower rail 4 of the main suspension body 2 are set in a balanced manner, and the fixed slot 5 at the top of the upper rail 3 is designed so that the hanging net structure can be stably connected to the installation arm 6 of the venue, ensuring the stability of the entire hanging net structure during use, effectively avoiding safety hazards caused by structural loosening or shaking, and also ensuring the stable display of suspended items, thus improving the safety and reliability of use.

[0043] Furthermore, the connecting piece 7 makes the splicing between two adjacent hanging bodies 2 simpler and faster. A firm connection can be achieved simply by fixing with bolts. The connecting piece 7 is housed in the internal space of the upper track 3, which not only ensures the stability of the splicing but also does not affect the overall aesthetics. This simplifies the installation process, reduces construction difficulty and cost, and improves construction efficiency.

[0044] Finally, the sliding design and unique structure of the hook 1 allow for flexible adjustment of the position of suspended items as needed, without disassembling the entire hanging net structure. This greatly improves the flexibility and convenience of the hanging net structure during use, allowing users to quickly adjust and replace suspended items according to different display needs or usage scenarios. This extends the service life of the hanging net structure and enhances its economy and practicality. Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0045] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
