Description

Technical Field

[0001] This utility model belongs to the field of plastic running track technology, and specifically relates to an EPDM plastic running track. Background Technology

[0002] Plastic running tracks, also known as all-weather athletic tracks, are composed of polyurethane prepolymer, mixed polyethers, waste tire rubber, EPDM rubber granules or PU particles, pigments, additives, and fillers. Plastic running tracks are characterized by good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties, which are conducive to athletes' speed and technique, effectively improving athletic performance and reducing the rate of falls and injuries. Composed of materials such as polyurethane rubber, plastic running tracks possess a certain degree of elasticity and color, and have a certain degree of UV resistance and aging resistance.

[0003] Currently, plastic running tracks need to be coated with dividing lines to form multiple tracks. However, the painted markings are easily erased after long-term use, affecting their clarity. Therefore, the process of recoating the markings is cumbersome, time-consuming, and difficult to apply accurately. Thus, there is a need for an EPDM plastic running track to solve the problems existing in the current technology. Utility Model Content

[0004] The purpose of this invention is to provide an EPDM plastic running track to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an EPDM plastic running track, including a support platform, with a plastic running track surface fixed to the upper surface of the support platform. A marking mechanism is provided inside the support platform, comprising a lifting bracket and a dividing line. The lifting bracket is slidably connected inside the support platform, and the dividing line is fixed to the upper end of the lifting bracket. A lifting mechanism is provided inside the support platform, comprising a lifting support plate, a lifting slide plate, and a height adjustment screw. The lifting support plate is fixed to the lower end of the lifting bracket, the lifting slide plate is fixed to the side surface of the lifting support plate, and the height adjustment screw passes through the interior of the lifting slide plate.

[0006] It should be noted in the solution that the support platform has a hollow lifting cavity inside, and the lifting plate is slidably connected in the hollow lifting cavity of the support platform.

[0007] It is worth noting that a lifting groove is provided on one side surface of the support platform, and the lifting slide plate is slidably connected in the lifting groove of the support platform.

[0008] Furthermore, it should be noted that a fixed support is fixed on one side surface of the support platform, and a lifting guide column is fixed on the upper surface of the fixed support at both ends. A lifting sliding hole is opened on the upper surface of the lifting slide plate at both ends, and the lifting guide column slides and the lifting sliding hole are slidably matched.

[0009] In a preferred embodiment, the upper part of the fixed support in the middle is rotatably connected to a height adjustment screw, the upper end of the height adjustment screw is fixed with a height adjustment knob, and the upper end face of the lifting slide plate in the middle is provided with a height adjustment screw hole, and the height adjustment screw is threadedly connected to the height adjustment screw hole of the lifting slide plate.

[0010] In a preferred embodiment, the upper surface of the plastic running track surface is provided with a clearance opening, the lifting bracket extends out of the clearance opening of the plastic running track surface, and the dividing line fills the clearance opening of the plastic running track surface.

[0011] Compared with the prior art, the EPDM plastic running track provided by this utility model has at least the following beneficial effects:

[0012] By setting up a marking mechanism, the plastic track surface is divided into multiple lanes by multiple dividing lines. Replacing the painted markings on the plastic track surface with dividing lines can reduce the difficulty of accurate marking construction and reduce the tedious steps of frequent subsequent coating.

[0013] By using the marking and lifting mechanisms, the height of the lifting platform and the dividing line can be adjusted, thus facilitating the upward adjustment of the clearance opening for filling the plastic track surface after the dividing line wears down on the upper surface.

[0020] Please see Figure 1-4 This utility model provides an EPDM plastic running track, including a support platform 1, with a plastic running track surface 2 fixed on the upper surface of the support platform 1. A marking mechanism is provided inside the support platform 1, which includes a lifting bracket 4 and a dividing line 5. The lifting bracket 4 is slidably connected inside the support platform 1, and the dividing line 5 is fixed to the upper end of the lifting bracket 4. A lifting mechanism is provided inside the support platform 1, which includes a lifting support plate 3, a lifting slide plate 6, and a height adjustment screw 12. The lifting support plate 3 is fixed to the lower end of the lifting bracket 4, the lifting slide plate 6 is fixed to the side surface of the lifting support plate 3, and the height adjustment screw 12 passes through the interior of the lifting slide plate 6.

[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the support platform 1 has a hollow lifting cavity 15 inside, and the lifting plate 3 is slidably connected in the hollow lifting cavity 15 of the support platform 1.

[0022] Further as Figure 3 As shown, it is worth noting that a lifting slide groove 10 is provided on one side surface of the support platform 1, and the lifting slide plate 6 is slidably connected in the lifting slide groove 10 of the support platform 1.

[0023] This solution has the following working process: During use, the plastic track surface 2 is fixed on the platform of the support 1, and the dividing lines 5 are filled into the clearance opening 14 of the plastic track surface 2 under the lifting support of the lifting bracket 4. In this way, the plastic track surface 2 is divided into multiple tracks by multiple dividing lines 5. The method of replacing the painted markings on the plastic track surface 2 with dividing lines 5 can reduce the difficulty of accurate marking construction and reduce the tedious steps of frequent subsequent coating.

[0024] As can be seen from the above work process: the plastic track surface 2 is divided into multiple tracks by multiple dividing lines 5. Replacing the painted markings on the plastic track surface 2 with dividing lines 5 can reduce the difficulty of accurate marking construction and reduce the tedious steps of frequent subsequent coating.

During use, the height adjustment screw 12 is rotated from the height adjustment knob 13, and the height adjustment screw hole 11 threadedly connected to the height adjustment screw 12 drives the lifting slide plate 6 to slide along the lifting slide groove 10 of the support platform 1. In this way, the lifting support plate 3 can be controlled to adjust the height of the lifting bracket 4 and the dividing line 5, so as to facilitate the upward adjustment of the clearance opening 14 of the filling plastic track surface 2 after the upper end face of the dividing line 5 is worn.
