Description

Technical Field

[0001] The invention relates to the technical field of table mats, in particular to a rubber-plastic antistatic table mat. Background Art

[0002] Patent application number 200910094567.9 discloses a slope-adjustable golf practice mat, comprising a base, a hitting pad mounted on the base, and a lifting mechanism disposed below the base. The base is characterized by a frame formed by two rigid members connected by a flexible member, and a panel mounted on the frame. A fixed frame is disposed below the base, and a diagonal brace is hingedly connected to the fixed frame. The other end of the diagonal brace is hingedly connected to the center axis of the flexible member between the two rigid members of the frame and connected to the lifting mechanism. This design not only eliminates the effects of stress on the base during slope changes, preventing deformation and damage to the panel mounted on the frame due to stress changes, but also maintains the stability and reliability of the base. This allows trainees to complete training similar to that on a golf course on the base with adjustable slope and slope direction, without any shaking or vibration that could affect their practice. Therefore, this is an ideal golf practice mat for on-site training.
