[0029] The utility model provides a lifting and folding treadmill, such as Figure 1-6 As shown, it includes a treadmill 1, a base 2, a bracket 3, an electric push rod 4 and a hook 5;
[0030] The running belt 13 is arranged along the front-back direction on the top side of the treadmill 1, focusing on Figure 3 As shown;
[0031] Focus on combination Figure 1 and Figure 6 As shown, the base 2 is located below the treadmill 1 and is used to support the ground. In order to save space when folded, the front-to-back length of the base 2 is smaller than the front-to-back length of the treadmill 1. The base 2 is located below the front of the treadmill 1.
[0032] The bottom end of the bracket 3 is pivoted to the base 2 through a pivot axis extending left and right, so that the top end of the bracket 3 can swing back and forth, and the top end of the bracket 3 is tilted backward and is pivoted to the front half of the treadmill 1 through another pivot axis extending left and right; one end of the electric push rod 4 is pivoted to the base 2 through a pivot axis extending left and right, so that the other end of the electric push rod 4 can swing back and forth, and the pivot point of the electric push rod 4 and the base 2 is located behind the pivot point between the bracket 3 and the base 2, and the other end of the electric push rod 4 is pivoted to the treadmill 1 through another pivot axis extending left and right, and the pivot point with the treadmill 1 is located in front of the pivot point between the bracket 3 and the treadmill 1; focus on the combination Figure 2 and Figure 5 As shown, the hook 5 is used to hook or release the front of the treadmill 1 on the base 2, so that the front of the treadmill 1 can be limited to lift up after hooking. When the electric push rod 4 is extended or retracted, the treadmill 1 is synchronously swung with the bracket 3, so that the rear of the treadmill 1 can be lifted up and the treadmill 1 can be erected and folded (emphasis on the combination of Figure 1 As shown), when the hook 5 releases the treadmill 1 from the base 2, the rear of the treadmill 1 falls on the ground. At this time, when the electric push rod 4 is extended and retracted, the bracket 3 swings back and forth, driving the front of the treadmill 1 to rise or fall, thereby adjusting the slope of the treadmill 1 (focus on the combination of Figure 6 shown).
[0033] Focus on combination Figure 2 、 Figure 5 As shown, in a preferred embodiment, a transverse pin 6 is provided on the base 2, and the axis of the transverse pin 6 is coaxial with the pivot axis of the bracket 3 on the base 2.
