As shown in Figures 1-5, the present application relates to an expansion structure of a treadmill, which includes: a column tube assembly movably arranged on both sides of the treadmill, the column tube assembly including: a first column tube 2-1, arranged on the left side of the treadmill, a second column tube 2-2, arranged on the right side of the treadmill, and a cross tube assembly, arranged between the first column tube 2-1 and the second column tube 2-2; the length of the first column tube 2-1 and the second column tube 2-2 is longer than the length of the treadmill, and the width is less than the width of the treadmill

Specifically, the expansion structure of the treadmill includes a treadmill and an expansion structure. In this embodiment, the body of the treadmill is thinned so that the treadmill body is both light and can achieve the effect of treadmill exercise. Among them, the column tube assembly is two column tubes, which are respectively installed at the front ends of the left and right sides of the treadmill body. The first column tube 2-1 is movably installed on the left side of the treadmill, and the second column tube 2-2 is movably installed on the right side of the treadmill. In this way, the column tube assembly can be folded and placed on the left and right sides of the treadmill. When the athlete needs handrails to support the exercise, the column tube assembly is unfolded. In this way, the column tube assembly stands on both sides of the basic bracket, so that the athlete can support his body with both hands on the handrails on the column tube assembly to run or walk. If storage is needed, turn off the treadmill and fold the column tube assembly. Because the treadmill body The treadmill is thinner and does not take up too much space. When the athlete does not need to use the handrail to support himself, the column tube assembly can be folded. At this time, the column tube assembly is placed on both sides of the treadmill, and will not protrude from the treadmill or collide with the treadmill body, so that the athlete can walk or exercise directly on the treadmill. The length of the first column tube 2-1 and the second column tube 2-2 is set to be slightly longer than the length of the basic bracket, and the width is slightly smaller than the width of the basic bracket, so that when the device is folded, the cross tube assembly between the first column tube 2-1 and the second column tube 2-2 will be placed outside the basic bracket, will not collide with the treadmill, and will not protrude above the basic bracket, thereby preventing the athlete from bumping into the column tube assembly when exercising on the treadmill in the folded state, which is both beautiful and safe.
