Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary materials for paving building materials, relates to floor auxiliary materials, and in particular to a shock-absorbing pad used for sports floors. Background Art

[0002] Sports flooring is generally made of a variety of composite materials. Its basic structure includes: surface flooring, subflooring, moisture-proof layer, keel layer and shock-absorbing pad. Compared with ordinary flooring, the biggest difference is that it can provide sports protection. It needs to be able to withstand high-intensity and high-load sports for a long time, and can minimize the impact load on the body when athletes complete jumping, sudden stops, and turns on the sports floor.

[0003] The shock-absorbing pad cooperates with the multi-layer structure of the sports floor to provide shock-absorbing function for the entire sports floor. The shock-absorbing pad layer is the medium between the entire wooden structure and the ground. It can make the underlying structure bear force evenly, ensure the elasticity of the sports floor structure, improve the shock-absorbing performance of the floor, reduce the impact force during exercise, protect the athlete's ankle joints, meniscus, spine and brain, and at the same time ensure the rebound rate of the ball, so that athletes have a better sports experience.

[0004] At present, the commonly used shock-absorbing pads for traditional sports floors on the market are butterfly-shaped, rectangular, etc. The quality of traditional rubber shock-absorbing pads varies. Such shock-absorbing pads can only absorb and disperse a small part of the vibration, and the impact absorption rate and repeated shock absorption effect of intense exercise are not ideal, and the service life is limited. Therefore, the utility model discloses a shock-absorbing pad for sports floors. Summary of the invention

[0005] In order to solve the deficiencies of the existing sports floor shock-absorbing pads, the utility model provides a high-performance sports floor shock-absorbing pad.

[0006] Technical Solution

[0007] A shock-absorbing pad used for sports flooring comprises a supporting shock-absorbing pad, wherein a placement cavity is provided in the surface of the supporting shock-absorbing pad and the lower part thereof is connected to a bridge-type shock-absorbing support, a plurality of buffer cavities are evenly arranged inside the placement cavity and a contact shock-absorbing surface is provided above the placement cavity, a plurality of buffer columns are provided on the contact shock-absorbing surface opposite to the placement cavity, and the shapes of the buffer cavities and the buffer columns are adapted to each other.

[0008] In a preferred disclosed example of the utility model, the height of the buffer column is less than half of the depth of the buffer cavity to ensure that sufficient air is reserved in the buffer cavity.

[0009] In a preferred disclosed example of the utility model, the number of the buffer columns is 2 to 4, preferably 6, and the number of the buffer cavities is consistent with the number of the buffer columns.

[0010] In a preferred disclosure example of the present utility model, the support shock pad and the bridge-type shock absorber support connected thereto below are integrally formed.

[0011] In a preferred disclosure example of the present utility model, the bridge-type shock absorber support is in the shape of a T-shaped platform.

[0012] Furthermore, a V-shaped groove is centrally opened at the bottom of the bridge-type shock absorber support, and the height of the V-shaped groove is not higher than one-half, preferably one-third, of the bridge-type shock absorber support.

[0013] In a preferred disclosure example of the present utility model, the material of the shock pad is thermoplastic elastomer TPE.

[0014] TPE is a material that combines the high elasticity and aging resistance of traditional vulcanized rubber, and at the same time has the convenience and versatility of plastic processing. It is also called artificial rubber or synthetic rubber. According to different use environments, this material has excellent thermal performance and material stability in a wide temperature range and non-polar materials, and is an ideal damping material.

[0015] Beneficial effects

[0016] The present utility model discloses a high-performance sports floor shock pad. A sports floor is laid above the shock pad. When the surface of the sports floor is impacted, after the shock-absorbing surface receives the impact force, there is air in the buffer cavity below the shock-absorbing surface and the V-shaped buffer groove in the bridge-type shock absorber support. The air damping can buffer the extrusion force received by the shock-absorbing column and has the function of sound insulation and noise reduction. At the same time, the bridge shock absorber support can transmit the impact force along the thrust line of the V-shaped buffer groove to the bridge-type shock absorber support, playing a role in long-term shock absorption and bearing pressure. The shock pad made of thermoplastic elastomer TPE can effectively absorb and dissipate the vibration and noise generated during sports. TPE has excellent aging resistance, so the shock pad has a long service life. Compared with traditional shock pads, it has efficient and stable shock absorption and protection capabilities, meeting the requirements of elasticity, durability, environmental protection, moisture and corrosion resistance, etc. required by the professional sports floor structure system.

[0021] In order to make the content of the present utility model easier to be clearly understood, the following further details the present utility model according to specific embodiments in conjunction with the accompanying drawings.

[0022] As Figures 1 to 3 shown, a shock-absorbing pad applied to a sports floor, the overall material of which is thermoplastic elastomer TPE. The contact shock-absorbing surface 1 and the support shock-absorbing pad 2 are connected by ultrasonic welding or cold welding fluid process. The diameters of the buffer column 3 inside the contact shock-absorbing surface 1 and the buffer cavity 5 inside the support shock-absorbing pad 2 are the same. The height of the buffer column 3 is less than half of the depth of the buffer cavity 5 to ensure that enough air is reserved in the buffer cavity. When the contact shock-absorbing surface 1 is subjected to an impact force, the plane disperses the impact force onto the buffer column 3. Since the compressibility of air is relatively large, it can withstand a large displacement and is used to dissipate the vibration and noise brought by the impact.

[0023] The support shock-absorbing pad 2 and the bridge-type shock-absorbing bearing 6 provided below it are integrally formed. The bridge-type shock-absorbing bearing 6 draws on the force-bearing characteristics of an arch bridge and bears the thrust transmitted by the V-shaped groove 7 through a large volume and gravity structure. When an impact force acts on the surface of the sports floor, under the vertical load of the V-shaped groove 7, the air damping in the V-shaped groove can buffer a part of the load, and the remaining load will generate a vertical reaction force at the support and also generate a horizontal thrust. The horizontal thrust will be transmitted along the thrust line to the bridge-type shock-absorbing bearing 6, which can effectively reduce the tensile stress on the lower side of the component and even prevent tensile stress from appearing in the component, improve the load-bearing capacity of the structure, disperse the impact force, and achieve the shock-absorbing effect.

[0024] The shock-absorbing pad applied to a sports floor disclosed by the present utility model includes a contact shock-absorbing surface 1, a support shock-absorbing pad 2, a buffer column 3, a placement cavity 4, a buffer column 5, a bridge-type shock-absorbing bearing 6 and a V-shaped groove 7. In the overall structure of the sports floor, the shock-absorbing pad is the main medium connecting the wooden structure and the ground. After the moisture-proof layer is completed on the ground, the shock-absorbing pad is installed on the ground, and then the wooden structure of the sports floor is installed on the shock-absorbing pad. A keel layer, a moisture-proof layer, a baseboard layer and a surface floor are installed above the sports floor shock-absorbing pad to form a complete sports floor. The impact absorption rate of this sports floor is more than 60%, and the ball rebound rate is more than 93%.

[0025] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the specification of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
