Description

Technical Field

[0001] This utility model relates to the field of sports field lines, and in particular to a quick fixing device for elastic beach ball court lines. Background Technology

[0002] Beach korfball is an emerging beach sport that has gradually gained popularity in recent years. Unlike indoor korfball, beach korfball courts are set on the beach, and the way the court lines are fixed presents unique challenges.

[0003] In beach cricket, court lines are a crucial element. Because it's a relatively new sport with limited professional equipment, substitutes are often used as court lines. These methods of marking court lines have several drawbacks. Common temporary marking methods, such as drawing directly on the sand surface with lime powder or paint, are easily affected by sea winds, waves, and human activity, leading to blurred lines that require frequent repainting, resulting in high maintenance costs and wasted manpower and resources. Furthermore, if these temporary marking materials are washed into the ocean, they may pollute the marine ecosystem. And some... While court lines laid with physical isolation materials, such as plastic or rubber strips, can solve the problem of markings easily disappearing to some extent, in actual use, due to the unevenness of the sand surface and the fluidity of the sand grains, these materials are prone to shifting or lifting. This not only affects the accuracy of the court lines but may also pose safety hazards such as tripping and sprains to athletes. In addition, these alternative court line laying methods cannot adapt to the special elasticity requirements of the sand, increasing the risk of sports injuries caused by court lines getting tangled in the feet, legs, or other body parts during fast running and intense offense and defense.

[0004] With the increasing popularity of beach korfball and the continuous improvement of competitive levels, higher requirements have been placed on the stability, durability, safety, and elasticity of beach korfball court lines. Existing court line technology can no longer meet these needs, and the darkness of the beach at night makes the court inconvenient to use. There is an urgent need to develop a quick fixing device technology for elastic beach korfball court lines to solve the above problems and improve the quality and safety of beach korfball courts.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-3As shown, a quick-fixing device for beach ball elastic court lines includes a main body 1. A lighting strip 15 is arranged around the upper circumference of the main body 1. LED lights 16 are installed inside the lighting strip 15. A fixing cloth strip 17 is provided at the connection point between the lighting strip 15 and the elastic court line strip 4. Cloth-covered straps 13 are provided at the four corners of the lighting strip 15 and the four corners of the elastic court line strip 4. Fixing threads are sewn between the cloth-covered straps 13 and the elastic court line strip 4. 14. A wiring harness 8 is provided at one end of the lighting strip 15, and a battery 6 is provided at the other end of the wiring harness 8. A battery box 5 is placed on the outer wall of the battery 6. A box door 7 is provided on the upper side of the battery box 5. A first sandpit 2 is provided outside the battery 6. A circular piece 9 is provided near the upper side of the box door 7. An elastic rope 10 passes through the middle of the circular piece 9. A first knot 11 is provided at one end of the elastic rope 10, and a second knot 12 is provided at the other end of the elastic rope 10. Reflective strips 18 are provided at equal intervals on the surface of the elastic field line strip 4. A second sandpit 3 is provided near the first sandpit 2.

[0025] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the four corners of the lighting strip 15 are sewn to the four corners of the elastic court line strip 4 through the cloth wrapping tape 13 and the fixing line 14. The lighting strip 15 and the elastic court line strip 4 are sewn together through the fixing cloth tape 17. The reflective strip 18 is fixedly sewn to the elastic court line strip 4. One end of the elastic rope 10 is fixedly connected to the elastic court line strip 4 through the second knot 12. The other end of the elastic rope 10 is fixedly connected to the disc 9 through the first knot 11. The battery 6 is electrically connected to the battery box 5. The lighting strip 15 is fixedly connected to the wire harness 8. The wire harness 8 is electrically connected to the battery 6. The box door 7 is detachably installed to the battery box 5. The reflective strip 18 is provided in six sets, which are distributed at equal intervals on the outer wall of the elastic court line strip 4.

[0026] The elastic cord 10 is 40cm long and 6mm in diameter to ensure sufficient elasticity and stability. The disc 9 is 5mm thick and 10mm in radius, with a 6.5mm hole in the center to facilitate the connection of the elastic cord 10.

[0027] Among them, the elastic court line strip 4 is made of fiber woven flat strip, which has the characteristics of UV resistance, corrosion resistance and high temperature resistance. It can be used for a long time in the beach environment without aging or damage, reducing the need for frequent replacement and maintenance.

[0029] The four corners of the strip are sewn to the lighting strip 15 by the fabric wrapping tape 13 and the fixing line 14, and the edge of the strip is further reinforced by the fixing fabric tape 17 and the lighting strip 15.

[0030] The workflow of this utility model is as follows: Using the quick fixing device for the elastic court lines of the beach ball game designed in this scheme, the court boundaries are marked according to the international beach ball game rules. An external laser positioning instrument is used to calibrate the 20m sidelines and 10m endlines, and the pre-embedded points are marked. Anchor points are evenly distributed on each sideline. Using a special sand drilling tool with a hole diameter ≥20cm and a depth ≥40cm, the first sand pit 2 and the second sand pit 3 are vertically excavated at the marked points, ensuring that the hole walls are smooth and do not collapse. The circular piece 9 is vertically inserted into the hole, and the bottom is filled and compacted with sand to a depth of 40cm. Then, sand is backfilled and compacted to form a stable anchoring layer. The lighting strip 15 is fixed to the surface of the elastic court line plate 4 by sewing through the fixing cloth strip 17. The four corners of the elastic court line plate 4 are connected to the lighting strip 15 by sewing with the cloth wrapping strap 13. This design facilitates the reinforcement of the lighting strip 15. By placing the battery 6 inside the battery box 5 and connecting the wiring harness 8, it is easy to activate the LED lights 16 inside the lighting strip 15, enabling it to provide illumination and facilitating nighttime use of the field. By embedding the circular piece 9 at one end of the elastic rope 10 into the first sandpit 2 and the second sandpit 3, and sewing one end of the elastic rope 10 to the outer wall of the elastic court line strip 4 through the second knot 12, and fixing the other end of the elastic rope 10 to the bottom of the circular piece 9 through the first knot 11, the rectangle formed by the elastic court line strip 4 facilitates the formation of a beach hockey elastic court line. The reflective strip 18 serves as a nighttime indicator for the elastic court line strip 4, facilitating nighttime use of the beach hockey field. Furthermore, the elastic court line strip 4 has the advantages of good stability, high durability, easy installation, minimal impact on the beach environment, and high safety.
