Description

Technical Field

[0001] This utility model relates to the field of fencing technology, specifically a sports field fencing with elastic connection to prevent ball impact. Background Technology

[0002] Stadium fencing refers to protective fencing used around stadiums, sports fields, and other similar venues; it is also commonly known as sports fencing or sports guardrails. It is mainly used for the separation, protection, and safety isolation of areas such as football fields, basketball courts, badminton courts, athletic fields, and tennis courts. An existing type of easily assembled and disassembled stadium fencing (publication number: CN222501259U) has revealed at least the following defects in use:

[0003] 1. Insufficiently flexible connection points are prone to bolt loosening, weld cracking, or clip detachment after strong impacts, which can lead to partial collapse of the fence, posing safety hazards to athletes and spectators. Excessively rigid connections cannot absorb impact, resulting in unpredictable ball rebounds at high speeds, increasing the possibility of accidental injury. Therefore, a flexible connection method is needed for stadium fences.

[0004] 2. The energy from high-speed impacts of all balls acts directly on the main perimeter fence. Prolonged, high-frequency impacts can cause fatigue, loosening, deformation, or even breakage of the wire mesh, chain link mesh, or welded joints. Therefore, a double-layer structure is needed to protect the stadium fence from ball impacts. Utility Model Content

[0005] The main purpose of this utility model is to provide a sports field fence with elastic connection to prevent ball impact, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A type of elastic sports field fencing designed to withstand ball impacts includes a fixed base, outer posts, and an outer net. The fixed base is fitted with outer and inner posts. Several connecting springs are installed on the inner sides of both the outer and inner posts, securing the outer net and the elastic inner net. A top rain shield is installed on the upper part of the outer and inner posts. Both the fixed base and the top rain shield have several fixing holes. The fixed base is connected to another fixed base via a bottom connecting plate, and the top rain shield is connected to another top rain shield via a top connecting plate.

[0008] Preferably, the outer column and inner column are threadedly connected to the fixed base.

[0009] Preferably, the outer and inner columns are threadedly connected to the top rain shield.

[0010] Preferably, several detachable connecting rods are installed between the outer column and the inner column.

[0011] Preferably, the top rain shield is provided with a waterproof groove.

[0012] Preferably, a fixing bolt is installed inside the fixing hole.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By installing connecting springs, the system can provide a comprehensive range of functions, including energy absorption and buffering, automatic rebound, force damping, and environmental adaptability, ensuring high safety, long lifespan, and easy maintenance for stadium fencing.

[0015] 2. By installing external and internal netting, the instantaneous peak stress on the main netting and posts can be effectively reduced, preventing the wire mesh, chain link mesh, or welded joints from loosening, deforming, or even breaking due to high-frequency impact, thus fundamentally improving the impact resistance of the fence.

[0023] Example

[0024] Please see Figure 1-3 The present invention provides the following technical solution:

[0025] An impact-resistant, elastic sports field fence includes a fixed base 1, outer posts 2, and an outer net 4. The outer posts 2 and inner posts 3 are installed on the fixed base 1. Several connecting springs 11 are installed on the inner sides of the outer posts 2 and inner posts 3. The connecting springs 11 fix the outer net 4 and the elastic inner net 5. A top rain shield 6 is installed on the upper part of the outer posts 2 and inner posts 3. The fixed base 1 and the top rain shield 6 are provided with several fixing holes 9. The fixed base 1 is connected to another fixed base 1 through a bottom connecting plate 8. The top rain shield 6 is connected to another top rain shield 6 through a top connecting plate 7.

[0026] Specifically: the outer column 2 and the inner column 3 are threadedly connected to the fixed base 1.

[0027] Specifically: the outer column 2 and the inner column 3 are threadedly connected to the top rain shield 6.

[0028] Specifically: Several detachable connecting rods 12 are installed between the outer column 2 and the inner column 3.

[0029] Specifically: the top rain shield 6 is provided with a waterproof groove.

[0030] Specifically: a fixing bolt 10 is installed inside the fixing hole 9.

[0031] In this embodiment, several connecting springs 11 are installed on the inner sides of both the outer post 2 and the inner post 3. In this sports field fencing designed to withstand ball impacts, the connecting springs 11 serve as core buffer components, significantly improving overall performance and safety in multiple aspects. First, the connecting springs 11 undergo instantaneous deformation and extend the stress time upon ball impact, effectively absorbing and dispersing the instantaneous impact force, significantly reducing the peak pressure on the netting surface and posts, and preventing structural damage such as loose bolts, cracked welds, or detached clips, fundamentally enhancing the fencing's impact resistance.

[0032] Secondly, the connecting spring 11 can automatically rebound after being subjected to force, continuously maintaining the tension of the net surface and preventing loosening and sagging due to prolonged use. At the same time, the flexible cushioning makes the ball's rebound speed and angle more gentle and controllable, reducing the risk of secondary injury and preventing high-speed rebounds from affecting the safety of athletes and the rhythm of the game.

[0033] Furthermore, the multi-point distributed connecting springs 11 can even out the force at each connection point, disperse the high stress caused by local impacts, protect bolts and welds from fatigue accumulation, and delay fatigue failure of the mesh and columns. At the same time, the flexible deformation of the connecting springs 11 can also reduce the noise generated by direct impact of the metal mesh, creating a more comfortable operating environment.

[0034] Furthermore, the stiffness and preload of the connecting spring 11 can be flexibly adjusted according to the impact intensity of different sports such as football, basketball, or tennis, exhibiting excellent adaptability and adjustability. It also allows for a certain degree of installation error and temperature expansion and contraction, avoiding internal stress caused by foundation settlement or thermal expansion and contraction. The connecting spring 11, made of weather-resistant steel or plastic-coated, maintains stable mechanical properties even in outdoor environments, extending the overall service life of the fence and reducing maintenance frequency and total lifespan cost.

[0035] In summary, the connecting spring 11 provides a high-safety, long-life, and easy-to-maintain system guarantee for the stadium fence through its comprehensive functions of energy absorption and buffering, automatic rebound, force component shock absorption, and environmental adaptability. It is a key design element for improving the impact resistance performance of the fence.

[0036] In this embodiment, the connecting spring 11 secures the outer net 4 and the elastic inner net 5. This double-layer structure of the sports field fencing, designed to protect against ball impacts, achieves superior performance, durability, and user experience compared to traditional single-layer fencing through the coordinated action of the outer net 4 and the elastic inner net 5. Firstly, the outer net 4 acts as the first line of defense, providing initial interception and deceleration. The elastic inner net 5 continues to deform and absorb remaining kinetic energy after the outer net 4 absorbs the force, effectively acting as a "secondary buffer." This tiered energy absorption design effectively reduces the instantaneous peak stress on the main net and posts, preventing the wire mesh, chain link mesh, or welded joints from loosening, deforming, or even breaking due to high-frequency impacts, fundamentally improving the fencing's impact resistance.

[0037] Secondly, the two layers of netting work together to bear the impact force, significantly reducing the fatigue accumulation of a single layer of netting under long-term stress. Even if the outer netting is partially worn or damaged, the inner netting can still maintain basic protection, greatly extending the overall service life of the fence, reducing replacement and maintenance costs, and ensuring that the sports field remains stable and reliable under high-frequency use.

[0038] Furthermore, the flexible cushioning of the elastic inner net 5 effectively controls the speed and direction of the ball's rebound, making the rebound softer and more controllable, reducing secondary injuries to athletes caused by high-speed rebounds. At the same time, the mutual support of the double-layered net makes the overall structure flatter and more stable, reducing slackness, sagging, and local bulging caused by long-term stretching of a single net, maintaining a neat appearance and uniform tension of the net, and improving the overall aesthetics.

[0039] Furthermore, after a ball impacts the outer net, some of its energy is absorbed, resulting in less residual kinetic energy being transferred to the inner net. This reduces the high-frequency noise generated by direct impact with the metal net, improving the comfort of the playing environment. Overall, the double-layer structure, through its "hard outer layer and soft inner layer" buffering, achieves a comprehensive effect of impact dispersion, extended lifespan, safe rebound, and simplified maintenance, providing a higher level of protection and a better sports experience for frequently used sports fields such as football and basketball courts.
