Technical Field

[0001] The utility model belongs to the technical field of treadmills, and in particular relates to a wear-resistant and shock-absorbing composite running board. Background Art

[0002] A general treadmill includes a platform, a running board body fixed at the bottom of the platform, two shafts respectively arranged at two sides of the running board body, and a running belt wound around the shafts. The top side of the running belt is supported by the running board body, and can be stepped on by an operator to achieve the purpose of running and fitness.

[0003] For example, the existing treadmill body is made of high-density board, which has poor appearance and high friction coefficient, and only a resin layer is pasted on the high-density board, which has poor cushioning performance. When exercising, the foot directly contacts the treadmill through the running belt, resulting in a large impact on the knees when running. Utility Model Content

[0006] The three-dimensional nylon elastic layer is formed by 3D winding of polyamide material layer by layer, and the polyamide material is spirally laid on the first polyurethane structural layer.

[0007] The wear-resistant layer is graphene, wear-resistant PET material or wear-resistant HDPE material.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] The utility model discloses a wear-resistant and shock-absorbing composite treadmill. A first polyurethane structural layer, a three-dimensional nylon elastic layer, a second polyurethane structural layer and a graphene wear-resistant layer are arranged on a treadmill body, so as to improve the buffering performance and reduce the damage of the treadmill to the human knees, and the wear resistance is increased by the graphene wear-resistant layer.
