Abstract: A treadmill, including a running platform, which includes a driving piece, a supporting piece and a border; the border is movably connected to the driving piece; the supporting piece is movably connected to the driving piece and is movably connected to the border; and the driving piece optionally drives the supporting piece to move to drive the border to move. In this way, a shorter translation stroke of the driving piece is converted into a longer rotating stroke of one end of the supporting piece through the supporting piece. Therefore, a stroke of the driving piece driving the running platform to move up and down can be enlarged, so that in a case that a longer stroke is required for adjustment, in-place adjustment can be achieved within a short time, and the requirement of rapid adjustment by a user can be met while energy consumption, noise and cost are reduced.

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.

Abstract: Provided is a treadmill capable of adjusting rising and falling by a folding block, including: a running platform; a running frame, configured to bear the running platform; and at least one adjusting mechanism, arranged below the running frame and including a supporting frame and a folding block. The supporting frame is connected to the running frame; the folding block includes a rotating connection part rotatably connected to the supporting frame, and a supporting part fixedly connected to the rotating connection part; and the adjusting mechanism adjusts a slope of the treadmill by the folding block rotatably connected to the supporting frame.

Abstract: A folding mechanism for an armrest handle of a treadmill is provided, including: an armrest handle having left and right bottom ends that are configured to be connected to a treadmill; a rotational assembly, including: a connecting rod, a limiting member being provided on a left section of the connecting rod, and a diameter of the limiting member being greater than a diameter of the connecting rod; a rotation control plate, an arc-shaped sliding groove being disposed on the rotation control plate, one end of the sliding groove being provided with a limiting hole that is in communication with the sliding groove, a width of the sliding groove being greater than a width of the connecting rod and less than a width of the limiting member, and a diameter of the limiting hole being greater than the diameter of the limiting member.

Abstract: The present application relates to a mini foldable treadmill, a lower end of the strut is rotatably connected to one end of a running plate; a part of the swivel arm near the middle of the swivel arm is hinged to the strut by an second rotation axis, a connector is disposed at the lower end of the swivel arm, which is connected to the upper end of the transmission portion, the lower end of the transmission portion is connected to the upper end of the spring pin, the spring pin is slidably mounted at the lower end of the strut, a fastener is disposed on the running plate, a pin hole is disposed thereon, and the spring pin is driven to extend so that the strut is in an upright state or driven to retract so that the strut is not in an upright state.
