Treadmill capable of adjusting slope rising and falling by screw rod

Abstract

Provided is a treadmill capable of adjusting slope rising and falling by a screw rod, including: a running platform; a running frame, configured to bear the running platform; a lifting frame, arranged below the running frame, configured to adjust the slope of the treadmill and including a side arm, one end of the side arm being pivoted to the running frame; and a driving mechanism, including a lead screw, the lead screw being in sleeving connection with a screw sleeve in a matching manner, and an outer side of the screw sleeve being rotatably connected to a supporting arm. The driving mechanism is arranged between the running frame and the lifting frame; the screw sleeve is driven by rotating the lead screw, so that the screw sleeve reciprocates on the lead screw; and the lifting frame is driven by the supporting arm to adjust the slope of the treadmill.
