Description

Technical Field

[0001] This utility model relates to the field of plastic sports flooring technology, and in particular to a puncture-resistant plastic sports flooring. Background Technology

[0002] With the rise of the national fitness craze, the demand for sports flooring in various sports venues such as gymnasiums, fitness centers, and school playgrounds is increasing. In the traditional sports flooring field, plastic sports flooring has become the first choice for many venues due to its good elasticity, anti-slip properties, and sound absorption effect.

[0003] In everyday sports scenarios, situations are complex and varied. During exercise, athletes' shoes can easily carry sharp objects. For example, after outdoor training, small stones, gravel, or other sharp foreign objects may become embedded in the soles of their shoes without being noticed. At the same time, sharp objects may fall onto the floor of sports venues due to various unexpected situations. Once these situations occur, existing plastic sports flooring is easily punctured due to its lack of sufficient puncture resistance. Therefore, improvements are needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a puncture-resistant plastic sports floor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a puncture-resistant plastic sports floor, comprising a wear-resistant layer, a puncture-resistant layer, a waterproof layer, and a foaming layer bonded together sequentially from the outside to the inside, wherein the puncture-resistant layer comprises a fiberglass layer and a rubber layer.

[0006] Preferably, one side of the glass fiber layer abuts against the wear-resistant layer, the other side of the glass fiber layer abuts against the rubber layer, and the cross-section of the foam layer is honeycomb-shaped.

[0007] Preferably, the waterproof layer is made of PVC, the wear-resistant layer is made of UV-cured coating, and the wear-resistant layer, puncture-resistant layer, waterproof layer, and foaming layer are bonded together with polyurethane adhesive.

[0008] Preferably, the top surface of the waterproof layer has horizontal serrated protrusions that abut against the bottom surface of the rubber layer, and the bottom surface of the waterproof layer has vertical serrated protrusions that abut against the foam layer.

[0009] Preferably, the bottom surface of the foamed layer is provided with an anti-slip texture, and the bottom surface of the anti-slip texture is uniformly provided with multiple large convex discs, and the top surface of the wear-resistant layer is provided with an anti-slip texture.

[0010] Preferably, the top surface of the rubber layer is uniformly provided with a plurality of limiting holes with an inverted T-shaped cross section, and the upper end diameter of the limiting hole is smaller than the bottom diameter of the limiting hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the close cooperation between the wear-resistant layer and the fiberglass layer, facilitates the dispersion of pressure applied by sharp objects, improves the puncture resistance of the floor surface, and thus effectively resists the puncture of sharp foreign objects carried by athletes' shoes and sharp objects dropped in the venue. Furthermore, through the synergistic effect of the fiberglass layer and the rubber layer, the fiberglass layer provides rigid support, and the rubber layer provides a certain buffer, which facilitates the absorption of puncture impact and improves the overall puncture resistance of the floor. This reduces damage caused by punctures and ultimately solves the problem of existing plastic sports flooring lacking puncture resistance and being easily punctured by sharp objects, thus improving the durability and service life of the floor.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4This utility model discloses a puncture-resistant plastic sports flooring, comprising, from the outside in, a wear-resistant layer 1, a puncture-resistant layer, a waterproof layer 2, and a foam layer 3, bonded together sequentially. The puncture-resistant layer includes a fiberglass layer 4 and a rubber layer 5. The wear-resistant layer 1 is made of UV-cured coating material, possessing high hardness and wear resistance, and can initially resist scratches from sharp objects. The fiberglass layer 4 has high strength and rigidity, effectively dispersing puncture force. The rubber layer 5 has good elasticity and cushioning properties, absorbing impact force. The combination of these three materials forms a puncture-resistant layer that significantly improves the flooring's puncture resistance. One side of the fiberglass layer 4 abuts against the wear-resistant layer 1, and the other side abuts against the rubber layer 5. The foam layer 3 has a honeycomb cross-section. The fiberglass layer 4 is tightly bonded to the wear-resistant layer 1 and the rubber layer 5. The honeycomb structure of the foam layer 3 allows for better pressure transmission and dispersion, providing excellent elasticity and sound absorption while reducing the weight of the floor and offering cushioning to enhance puncture resistance. The waterproof layer 2 is made of PVC, and the wear-resistant layer 1 is made of UV-cured coating. Polyurethane adhesive is used to bond the wear-resistant layer 1, puncture-resistant layer, waterproof layer 2, and foam layer 3 together. The PVC waterproof layer 2 has excellent waterproof performance, effectively preventing moisture from penetrating into the floor and protecting other structural layers. The UV-cured wear-resistant layer 1 is highly wear-resistant, and the polyurethane adhesive has high bonding strength, ensuring a tight bond between the layers and guaranteeing the stability and integrity of the floor structure, thereby improving puncture resistance.

[0020] In this invention, the top surface of the waterproof layer 2 has horizontal serrated protrusions 9 that abut against the bottom surface of the rubber layer 5, and the bottom surface of the waterproof layer 2 has vertical serrated protrusions 9 that abut against the foam layer 3. The horizontal and vertical serrated protrusions 9 increase the friction and contact area between the waterproof layer 2, the rubber layer 5, and the foam layer 3, making the bond between the layers stronger, improving the overall stability and puncture resistance of the floor, and also dispersing pressure to a certain extent. The bottom surface of the foam layer 3 has an anti-slip texture 6, and the bottom surface of the anti-slip texture 6 has multiple large raised discs evenly distributed. The top surface of the wear-resistant layer 1 has an anti-slip texture 8. The anti-slip texture 6 and the large raised discs increase the friction between the floor and the ground, preventing the floor from sliding and improving safety. The anti-slip texture 8 on the top surface of the wear-resistant layer 1... This increases the friction between the athlete's feet and the floor, reducing the risk of slipping, without affecting the floor's puncture resistance. The top surface of the rubber layer 5 is evenly provided with multiple inverted T-shaped limiting holes 7. The upper diameter of the limiting hole 7 is smaller than the bottom diameter of the limiting hole 7. During the manufacturing process, some fibers of the glass fiber layer 4 are precisely embedded in the inverted T-shaped limiting holes 7. Due to the unique upper-narrow and lower-wide structure of the limiting hole 7, the glass fiber is firmly held in place after being embedded, which greatly enhances the connection between the glass fiber layer 4 and the rubber layer 5. From the beginning of product molding, the two are closely connected, and their ability to work together is greatly improved. When faced with puncture by sharp objects, they can more effectively resist external forces together, further strengthening the floor's puncture resistance.

[0021] Working Principle: When this invention is used, if a sharp object comes into contact with the puncture-resistant plastic sports flooring, the outermost wear-resistant layer 1, made of UV-cured coating material with high hardness, first resists the scratch and slows down the damage to the internal structure. Subsequently, the puncture force is transmitted to the puncture-resistant layer, where the glass fiber layer 4 disperses the force in all directions due to its high strength and rigidity. Furthermore, some glass fibers are precisely embedded in the inverted T-shaped limiting holes 7 on the top surface of the rubber layer 5 during production. The tight mechanical interlocking ensures a close connection between the two. When subjected to puncture force, the rubber layer 5 absorbs the impact force using its good elasticity and cushioning properties, working in conjunction with the glass fiber layer 4 to greatly improve puncture resistance. In daily use, the honeycomb structure of the foam layer 3 gives the flooring good elasticity, providing comfort for athletes. The floor provides a comfortable feel and proper cushioning, reducing joint pressure. Its sound absorption effect can reduce sports noise, and it can absorb and disperse some of the puncture energy through structural deformation to assist in puncture resistance. The waterproof layer 2 is made of PVC material and is tightly bonded between the puncture-resistant layer and the foam layer 3. It effectively blocks the penetration of moisture such as athletes' sweat and condensation in the humid air in the venue, protecting the floor structure, preventing moisture-induced deformation and damage, and extending its service life. In terms of anti-slip, the anti-slip texture 6 and evenly distributed large convex discs on the bottom surface of the foam layer 3 are in close contact with the ground to prevent the floor from sliding and ensure stable installation. The anti-slip texture 8 on the top surface of the wear-resistant layer 1 directly provides reliable friction for the athlete's feet, ensuring sufficient grip when moving quickly, stopping suddenly, and turning sharply, reducing the risk of slipping and creating a safe sports environment.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
