Description

Technical Field

[0001] The utility model relates to the technical field of plastic runways, in particular to a wear-resistant and pressure-resistant plastic runway. Background Art

[0002] As a common surface material for sports venues, plastic tracks are widely used in track and field venues, playgrounds, and gymnasium tracks. Its notable features include excellent elasticity, outstanding wear resistance, excellent anti-slip properties, and effective shock absorption. These features together provide athletes with a high-quality sports experience and play an important role in safety protection during sports.

[0003] The general plastic track is divided into the subbase, elastic layer and surface layer. The subbase is the base layer of the plastic track, usually composed of concrete or asphalt foundation, which plays the role of supporting and stabilizing the entire track structure. The elastic layer is a key component of the plastic track, usually made of a mixture of rubber particles and special glue, with good elasticity and shock absorption performance, which can reduce the impact force of athletes when running and protect athletes from injury. The surface layer is the top covering layer of the track, usually made of wear-resistant and non-slip materials such as polyurethane or EPDM, with good friction and comfort, and can provide good grip and running feeling.

[0004] The patent with the current publication number CN212316597U discloses a plastic runway, including a casting frame, the front and rear sides of the top of the casting frame are both equipped with baffles, and reinforcing rods are evenly distributed between the baffles, the bottom of the casting frame is provided with a lime paste layer, the top of the casting frame is paved with a stone powder cement layer, the top of the stone powder cement layer is paved with an asphalt base layer, the top of the asphalt base layer is paved with a black granular layer, the top of the black granular layer is paved with a red granular layer, and the top of the red granular layer is coated with a polyurethane adhesive surface layer. The casting frame provided by the above technical solution enables the runway to achieve the effect of frame-type paving and installation through the baffles and reinforcing rods, further strengthening the overall strength of the runway, and the lime paste layer achieves a separation effect between the bottom of the runway and the foundation, reducing the moisture in the foundation from entering the interior of the runway, and maintaining the operating performance of the runway.

[0005] Although the above device solves the problem of weak strength and poor isolation of the plastic track, the following problems still exist:

[0006] During use, the existing plastic tracks have poor wear resistance. After a period of use, the plastic tracks will be greatly worn, which can easily cause athletes to slip and cause them to fall. In addition, the common plastic tracks have poor pressure resistance and are prone to aging and deformation, which brings great inconvenience to users. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a wear-resistant and pressure-resistant plastic track, thereby improving the wear resistance and pressure resistance of the plastic track.

[0008] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a wear-resistant and pressure-resistant plastic track, comprising a base layer, an elastic layer connected to the surface of the base layer, and a surface layer connected to the surface of the elastic layer, a connecting layer is fixedly connected between the base layer and the elastic layer, a supporting layer is fixedly connected between the elastic layer and the surface layer, and a plurality of diamond-shaped protrusions are fixedly connected to the surface of the surface layer.

[0009] Furthermore, the connection layer includes a plurality of connection blocks, and drainage grooves are formed between the connection blocks.

[0010] Furthermore, a waterproof layer is fixedly connected between the connecting layer and the base layer.

[0011] Furthermore, a support frame is fixedly connected in the support layer, a connection groove matching the position and shape of the support frame is opened in the support layer, and the support frame is composed of a plurality of support units.

[0012] Furthermore, the support unit includes two X-shaped frames and a connecting rod, both ends of the connecting rod are fixedly connected to the center of the X-shaped frames respectively, and the four ends of the two X-shaped frames are correspondingly fixedly connected.

[0013] Furthermore, the surface layer is provided with a plurality of staggered anti-skid grooves, which divide the surface layer into a plurality of rhombus blocks. The rhombus blocks are fixedly connected to the surfaces of the rhombus blocks, and a blank rhombus block is left between two adjacent rhombus blocks.

[0014] Furthermore, a diamond-shaped groove is provided on the surface of the diamond-shaped block between the two diamond-shaped protrusions.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model arranges diamond-shaped protrusions on the surface layer, arranges a connecting layer between the base layer and the elastic layer, and arranges a supporting layer between the elastic layer and the surface layer. The diamond-shaped protrusions can reduce the wear of the surface layer and improve the wear resistance of the surface layer, thereby increasing the service life of the surface layer.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] like Figures 1 to 5 As shown, a wear-resistant and pressure-resistant plastic track includes a base layer 1, an elastic layer 2 connected to the surface of the base layer 1, and a surface layer 3 connected to the surface of the elastic layer 2, a connecting layer is fixedly connected between the base layer 1 and the elastic layer 2, a supporting layer 7 is fixedly connected between the elastic layer 2 and the surface layer 3, and a plurality of diamond-shaped protrusions 10 are fixedly connected to the surface of the surface layer 3.

[0025] like Figure 1 As shown, the wear-resistant and pressure-resistant plastic track in the utility model is similar to the existing plastic track structure, such as a plastic track disclosed in the patent with publication number CN212316597U. The main improvement of the utility model is to improve the wear resistance and pressure resistance of the plastic track. Figures 1 to 5As shown, when a wear-resistant and pressure-resistant plastic track in the utility model is in use, when an athlete exercises on the plastic track, the diamond-shaped protrusions 10 will first contact the athlete and be worn first, and then the surface layer 3 will contact and wear with the athlete. The diamond-shaped protrusions 10 can reduce the wear of the surface layer 3 and increase the service life of the plastic track; when the plastic track is under pressure, the connection layer and the support layer 7 can increase the strength of the elastic layer 2 to avoid deformation of the elastic layer 2 under long-term pressure, and ensure that the plastic track remains as straight as possible under pressure, which is good for athletes. It brings convenience to personnel; the base layer 1 is composed of concrete or asphalt foundation, the elastic layer 2 is made of a mixture of rubber particles and special glue, the surface layer 3 is made of polyurethane or EPDM rubber, and the diamond-shaped protrusions 10 are made of hard materials, such as wear-resistant rubber or hard plastic, to enhance its wear resistance and improve the service life of the diamond-shaped protrusions 10. The connecting layer is made of polyurethane material or a special rubber mixture, has good elasticity and compression resistance, and also has good adhesion in a humid environment, so as to provide a stronger connection between the base layer 1 and the elastic layer 2.

[0026] By arranging diamond-shaped protrusions 10 on the surface layer 3, arranging a connecting layer between the base layer 1 and the elastic layer 2, and arranging a supporting layer 7 between the elastic layer 2 and the surface layer 3, the diamond-shaped protrusions 10 can reduce the wear of the surface layer 3, improve the wear resistance of the surface layer 3, and thus improve the service life of the surface layer 3. By utilizing the connecting layer and the supporting layer 7, the supporting capacity of the surface layer 3 is improved, thereby improving the overall compression resistance of the plastic track, thereby increasing the overall service life of the plastic track and bringing convenience to athletes.

[0027] like Figure 1 and Figure 2 As shown, the connection layer includes a plurality of connection blocks 4 , and drainage grooves 5 are formed between the connection blocks 4 .

[0028] Specifically, the drainage ditch 5 can discharge the infiltrated rainwater in time, preventing the rainwater from remaining in the plastic track to stink, rot, and corrode the plastic track.

[0029] like Figure 1 and Figure 2 As shown, a waterproof layer 6 is fixedly connected between the connecting layer and the base layer 1 .

[0030] Specifically, the waterproof layer 6 can ensure that rainwater will not penetrate into the base layer 1, and ensure that the base layer 1 will not be corroded by rainwater, thereby improving the corrosion resistance and service life of the base layer 1; the waterproof layer 6 is a polyvinyl chloride roll or an acrylic copolymer roll, etc. These rolls have good flexibility and anti-penetration properties, can effectively isolate rainwater and maintain a long-term waterproof effect.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, a support frame 9 is fixedly connected to the support layer 7, and a connecting groove 8 matching the position and shape of the support frame 9 is opened in the support layer 7. The support frame 9 is composed of a plurality of support units.

[0032] Specifically, the support frame 9 can improve the strength of the support layer 7 and the compressive resistance of the support layer 7 , and can also prevent the support layer 7 from breaking, thereby increasing the service life of the support layer 7 .

[0033] like Figure 5 As shown, the support unit includes two X-shaped frames 901 and a connecting rod 902. The two ends of the connecting rod 902 are fixedly connected to the center of the X-shaped frames 901 respectively, and the four ends of the two X-shaped frames 901 are fixedly connected accordingly.

[0034] Specifically, by using two X-shaped skeletons 901, multiple diamond and triangular structures can be formed in the support frame 9. The X-shaped skeleton 901 can disperse the pressure on the support layer 7, thereby improving the compression, tension and deformation resistance of the support frame 9, and the connecting rod 902 can provide support for the center of the X-shaped skeleton 901, further improving the compression resistance of the support frame 9, thereby improving the stability and compression resistance of the entire support layer 7.

[0035] like Figure 3 As shown, the surface layer 3 is provided with a plurality of staggered anti-skid grooves 11 , which divide the surface layer 3 into a plurality of rhombus blocks. The rhombus protrusions 10 are fixedly connected to the surface of the rhombus blocks, and a blank rhombus block is left between two adjacent rhombus protrusions 10 .

[0036] Specifically, the anti-skid groove 11 can increase the friction of the surface layer 3 to prevent athletes from slipping while running. It can also provide guidance and aggregation effects for liquids to keep the runway dry and further improve the anti-skid effect.

[0037] like Figure 3 As shown, a diamond groove 12 is formed on the surface of the diamond block between the two diamond shaped protrusions 10 .

[0038] Specifically, the diamond grooves 12 can further increase the friction of the surface layer 3 and provide athletes with better anti-slip ability. At the same time, the diamond grooves 12, diamond protrusions 10 and diamond blocks are uniform in shape, which helps to improve the aesthetics of the surface layer 3 and enhance the viewing and usage experience of athletes.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
