Description

Technical Field

[0001] This utility model belongs to the field of sports flooring technology, specifically relating to an integrated through-type elastic pad and a high-resilience sports floor. Background Technology

[0002] With the increasing awareness of fitness among the public and the rapid development of the sports industry, the demand for sports field construction in communities, schools, and public venues is growing. As an important component of basic sports facilities, sports flooring, due to its good resilience, convenient construction, and quick assembly / disassembly, has gradually replaced traditional plastic surfaces and is now widely used. Currently, most commercially available sports flooring is injection-molded from polyvinyl chloride (PVC), with multiple planks spliced ​​together to form a complete sports surface layer. Its surface is clean and aesthetically pleasing and provides a certain degree of rebound under foot pressure.

[0003] However, existing sports flooring still suffers from significant structural design flaws: most mainstream products employ a rigid column support structure. While this type of rigid support system provides basic load-bearing capacity, its impact absorption performance is severely inadequate. Test data shows that the impact absorption rate of single-layer structures is generally below 10%, and even double-layer structures are below 18%, far below international sports field standards (≥25%). Insufficient cushioning performance can easily lead to joint injuries in athletes, and the high-frequency vibrations from the rigid support also accelerate structural fatigue, significantly shortening the floor's lifespan.

[0004] To improve cushioning performance, some manufacturers have attempted to install insert posts and rubber pads on the bottom of the panel. While this approach can enhance elasticity, it has revealed several problems in practical applications: First, it requires separate mold manufacturing of the rubber pads and additional manual insertion, leading to increased production costs and reduced production efficiency. Second, the rubber pads and insert posts are often connected using a simple sleeve method, which can easily lead to detachment or misalignment under long-term dynamic loads, posing safety hazards. Third, existing rubber pads are mostly homogeneous cylindrical structures, and their layout with rigid support posts lacks mechanical optimization, resulting in localized stress concentration. This not only reduces the uniformity of rebound but also causes premature failure of the support structure. These problems collectively restrict the overall performance and market promotion of sports flooring. Utility Model Content

[0005] The present invention aims to provide an integrated through-type elastic pad and a high-resilience sports floor, solving the technical problems of insufficient impact absorption performance, low energy return performance, and high production cost of existing sports floor support structures.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] The integrated through-type elastic pad includes a support sleeve. The top of the support sleeve is provided with an anti-slip and wear-resistant surface, the bottom of the support sleeve is provided with a rubber shock-absorbing pad, and the outer wall of the support sleeve is provided with several inverted toothed push-in rings.

[0008] Furthermore, the bottom of the rubber shock-absorbing pad is provided with an anti-slip texture structure, which is composed of several anti-slip components, and all the anti-slip components are arranged in a ring array around the center of the bottom of the rubber shock-absorbing pad.

[0009] Furthermore, the anti-slip component includes a V-shaped groove with a V-shaped protrusion inside.

[0010] The high-resilience sports floor includes a sports panel, the bottom of which is provided with several rigid support cylinders. All the rigid support cylinders are arranged in a rectangular array. The rigid support cylinders are divided into first-type support cylinders and second-type support cylinders. The first-type support cylinders are located between two second-type support cylinders.

[0011] The motion panel has several round holes and water-permeable holes. The round holes are located at the top of the second type of support cylinder. The second type of support cylinder is equipped with the aforementioned integrated through-type elastic pad. The support sleeve is inserted into the second type of support cylinder. The rubber shock-absorbing pad is in close contact with the bottom surface of the second type of support cylinder.

[0012] Furthermore, the first type of support tube and the second type of support tube are connected by connecting ribs.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model adopts an integral molding design of the support sleeve and the rubber shock-absorbing pad, combined with the locking mechanism of the inverted tooth push-in ring and the multi-directional stress dispersion characteristics of the bottom V-shaped anti-slip texture, which greatly improves the impact absorption performance and exceeds international standards, while completely solving the safety hazard of easy detachment of traditional split rubber pads; through the matrix layout of rigid support cylinder and elastic support cylinder and the synergistic force design of trapezoidal connecting ribs, a rigid-flexible coupling buffer system is formed, which significantly improves the uniformity of rebound and extends the fatigue life of the structure; the optimized production process realizes the one-time molding of the elastic pad and the support structure, reducing the production complexity and improving the installation efficiency.

[0014] This invention ensures high resilience and sports safety while also providing long-term stability and ease of maintenance, systematically overcoming the technical bottlenecks of insufficient cushioning performance, easily damaged structure, and high maintenance costs of traditional sports flooring.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The present invention will be further described in detail below with reference to the embodiments.

[0026] A specific embodiment of a high-resilience sports floor provided by this utility model:

[0027] like Figure 1-4 As shown, the high-resilience sports floor includes a sports panel 1. The bottom of the sports panel 1 is provided with several rigid support cylinders 2. All the rigid support cylinders 2 are arranged in a rectangular array. The rigid support cylinders 2 are divided into first type support cylinders 3 and second type support cylinders 4. The first type support cylinders 3 are located between two second type support cylinders 4. Connecting ribs 5 connect the first type support cylinders 3 and the second type support cylinders 4.

[0028] The motion panel 1 has several round holes 6 and water-permeable holes 7. The water-permeable holes 7 facilitate rapid drainage. The round holes 6 are located at the top of the second type of support cylinder 4, and an integrated through elastic pad 8 is installed inside the second type of support cylinder 4.

[0029] like Figure 5-8As shown, the integrated through-type elastic pad 8 is integrally injection molded from the support sleeve 9 and the rubber shock-absorbing pad 10. The top of the support sleeve 9 is provided with an anti-slip and wear-resistant surface 11, which is frosted and has a friction coefficient ≥0.8. The rubber shock-absorbing pad 10 is 3mm thick and is located at the bottom of the support cylinder. The outer wall of the support sleeve 9 is provided with four sets of reverse toothed push-in rings 12. The integrated through-type elastic pad 8 is inserted into the second type of support cylinder 4 through the support sleeve 9. The reverse toothed push-in rings 12 ensure an interference fit between the support sleeve 9 and the inner wall of the second type of support cylinder 4. After installation, the rubber shock-absorbing pad 10 makes contact with the bottom surface of the second type of support cylinder 4. After the sports floor is laid, because the rubber shock-absorbing pad 10 is in contact with the ground, the bottom surface of the rigid support cylinder 2 is 3mm higher than the ground, forming a local buffer protrusion.

[0030] The bottom of the rubber shock-absorbing pad 10 is provided with an anti-slip texture structure, which is composed of several anti-slip components 15. All the anti-slip components 15 are arranged in a ring array around the center of the bottom of the rubber shock-absorbing pad 10. The anti-slip component 15 includes a V-shaped groove 16, and a V-shaped protrusion 17 is provided in the V-shaped groove 16. This structure increases the friction coefficient of the contact surface (dynamic friction coefficient ≥ 0.6) and forms a multi-directional drainage channel.

[0031] When the high-resilience sports floor of this embodiment is subjected to a vertical impact, the rubber shock-absorbing pad 10 first compresses and deforms, and the stress is dispersed by the V-shaped protrusion 17 structure. The rigid support cylinder 2 provides rigid support, and the connecting rib 5 coordinates the coordinated deformation of the first type of support cylinder 3 and the second type of support cylinder 4 to avoid stress concentration.

[0032] It should be noted that, in this document, terms such as “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
