Description

Technical Field

[0001] The utility model relates to a sports cushion structure, in particular to a cushion layer structure capable of realizing rapid drainage. Background Art

[0002] In the construction of some sports fields, such as the construction of artificial football turf, a cushion is usually laid under the turf. The cushion is usually installed under the artificial turf as the bottom cushion layer of the artificial turf, which is used to provide better elastic support and shock absorption effects. It can improve the overall performance of the artificial turf, increase the service life of the stadium, reduce the risk of player injury, and improve the safety and comfort of the game. Artificial football turf cushions are used in many professional football fields and training venues to ensure the safety and comfort of players.

[0003] However, after rain, there are certain problems with this structure, that is, rainwater cannot be effectively drained, especially it is easy to form water accumulation in lower-lying areas, which significantly reduces the utilization rate of the turf. Especially in areas with more rain, frequent rainfall will cause this artificial turf to be unable to be used normally. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a technology for realizing rapid drainage of rainwater and avoiding the problem of water accumulation on the turf.

[0005] To achieve the above purpose, the utility model provides a drainage cushion layer structure, which includes a substrate and a convex part. Multiple groups of the convex parts are arranged on the substrate, drainage grooves are formed between adjacent convex parts, at least three groups of drainage grooves form an intersection point, and the intersection point forms a drainage hole.

[0006] The beneficial effect of the above solution is that the cushion layer structure is set as a substrate and a convex part. When applied under the artificial turf, on the one hand, it plays a role in buffering and shock absorption; in addition, when rainwater occurs, the water flow will quickly enter the drainage holes on the substrate and then flow to the lower position, and then penetrate or gather together. And by setting drainage holes at the intersection positions of three groups of drainage grooves, it is more conducive to the rapid collection and discharge of water flow.

[0007] Preferably, multiple groups of the convex parts are arranged on the front surface of the substrate, and a drainage groove is provided on the back surface of the substrate, and multiple groups of the drainage holes are connected to the drainage groove.

[0008] The multiple drainage holes are connected together through the drainage groove below. In this way, when the rainwater flows down, it can flow uniformly along the drainage groove, which can guide the water flow to other positions and complete the drainage action faster.

[0009] Preferably, the convex portion has a regular hexagon structure, and drain holes are respectively provided at the positions of the opposite first vertex and the second vertex of the regular hexagon structure.

[0010] Preferably, the convex portion has a rhombus structure, and drain holes are provided at the vertex positions of the rhombus structure.

[0011] Preferably, a protective film layer is covered on the substrate and the convex portion.

[0012] Since there are openings at multiple sites on the substrate and there are drainage grooves below, the structural strength of the substrate will be reduced. To solve this problem, a protective film layer is added. The protective film layer can be attached to the surfaces of the convex portion and the substrate by bonding or hot pressing, which can prevent cracking when tearing the substrate, and the protective film layer has anti-corrosion and isolation properties, thereby avoiding oxidation and increasing the service life.

[0013] Preferably, the protective film layer is respectively located on the front and back sides of the substrate.

[0014] Preferably, the back side of the substrate has multiple groups of drainage grooves, and the drainage grooves are parallel to each other.

[0015] Preferably, the center of the convex portion is higher than the edge position. This is more conducive to water drainage.

[0016] Preferably, the convex portion forms a conical protrusion. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Next, in combination with the drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0026] As Figures 1 to 7 shown, the present utility model provides a drainage buffer cushion structure, which includes a base plate 10 and a convex portion 20. A plurality of groups of the convex portions 20 are provided on the base plate 10. Drainage grooves 21 are formed between adjacent convex portions 20. At least three groups of drainage grooves 21 form an intersection point 22, and a drainage hole 23 is formed at the intersection point 22.

[0027] The buffer cushion structure is set as the base plate 10 and the convex portion 20. When applied under an artificial lawn, on the one hand, it plays a role in buffering and shock absorption; in addition, when rainwater occurs, the water flow will quickly enter the drainage hole 23 on the base plate 10, then flow to the lower position, and then penetrate or gather together. And by providing the drainage hole 23 at the intersection position of the three groups of drainage grooves 21, it is more conducive to the rapid collection and discharge of the water flow.

[0028] Preferably, a plurality of groups of the convex portions 20 are provided on the front surface of the base plate 10, and a drainage groove 11 is provided on the back surface of the base plate 10. A plurality of groups of the drainage holes 23 are connected to the drainage groove 11.

[0029] The bottoms of the plurality of drainage holes 23 are connected together through the drainage groove 11. In this way, when the rainwater flows down, it can flow uniformly along the drainage groove 11, so that the water flow can be guided to other positions and the drainage action can be completed more quickly.

[0030] Preferably, the convex portion 20 is a regular hexagon structure. Drainage holes 23 are respectively provided at the first vertex position 81 and the second vertex position 82 of the regular hexagon structure. The bottoms of the drainage holes 23 corresponding to the first vertex position 81 and the second vertex position 82 are located in the same drainage groove 11.

[0031] Preferably, as Figure 3 and Figure 6As shown, the raised portion 20 has a diamond structure 61, and drain holes 23 are provided at the vertex positions of the diamond structure 61. It should be noted that drain holes can be opened at the vertex positions of the diamond structure as needed. Drain holes can be provided at the positions where three groups of diamond structures intersect, and the positions where three groups of diamond structures intersect are where three groups of drain grooves 21 meet; drain holes can also be provided at the positions where six groups of diamond structures intersect, that is, at the positions where six groups of drain grooves meet; and the drainage efficiency is higher when drain holes are provided at the positions where six groups of drain grooves meet.

[0032] Reference Figure 7 , preferably, a protective film layer 152 is covered on the substrate 10 and the raised portion 20.

[0033] Since there are openings at multiple sites on the substrate 10 and there are drainage grooves 11 below, this will cause the structural strength of the substrate 10 to decrease. To solve this problem, a protective film layer is added. The protective film layer can be attached to the surfaces of the raised portion 20 and the substrate by bonding or hot pressing, which can prevent cracking when the substrate 10 is torn, and the protective film layer has anti-corrosion isolation characteristics, thereby avoiding oxidation and increasing the lifespan.

[0034] Preferably, the protective film layer 152 is located on the front and back of the substrate 10 respectively.

[0035] Preferably, there are multiple groups of drainage grooves 11 on the back of the substrate 10, and the drainage grooves 11 are parallel to each other.

[0036] Preferably, the center of the raised portion 20 is higher than the edge position. This is more conducive to water drainage.

[0037] Preferably, the raised portion 20 forms a conical protrusion.

[0038] The substrate 10 and the raised portion 20 are made of XPE plastic, and XPE is an existing polyethylene foaming material.

[0039] The protective film layer is, for example, a film of the polyethylene terephthalate PET protective type.

[0040] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
