Description

Treadmill shock-absorbing buffer folding structure

technical field

The invention relates to a treadmill structure, especially a shock-absorbing, buffering and folding structure for a treadmill with shock-absorbing and folding functions.

Background technique

The currently known treadmill structure mainly includes a base frame, a frame, a pushing device and a positioning device. Provide the user to run on the belt frame, and one end of the belt frame is pivotally connected to the base frame and can rotate relative to the base frame, one end of the pushing device is connected to the base frame, and the other end of the pushing device One end is connected to the bottom of the belt frame, and the pushing device can be driven to produce telescopic changes. The positioning device is connected to one side of the base frame and the belt frame, and the positioning device can be a pneumatic cylinder. When the pushing device will When the top of the belt rack is high, the positioning device can support the belt rack to form a folded state.
