Furthermore, to increase training intensity, a lifting device 12 is provided at the bottom of the treadmill 11 on the front side of the frame 10, thereby raising the angle of the treadmill 11 and increasing the incline to simulate uphill running. Figure 2 As shown, the normal height of the running platform 11 above the ground is about 140mm, but the lifting device 12 can raise the running platform 11 by an angle (θ) of 210mm to 230mm, forming a high-angle running platform.

[0003] In a conventional treadmill 30, the running platform 11 has only one footrest 13 at the bottom left and right of the rear end, forming a two-point contact. Therefore, when the front end of the running platform 11 forms a... Figure 2 At the high angle (θ) shown, the support point is prone to instability. Especially when someone is running on the treadmill 11, the impact force is quite large, causing the frame 10 to shake severely, which not only causes noise but also poses a safety hazard.

[0004] Therefore, how to improve the above-mentioned problems is the primary issue that this utility model aims to solve. Utility Model Content

[0006] To achieve the above objectives, the present invention employs the following means: The present invention provides a stabilizing device for a high-angle running platform of a treadmill, comprising: a frame on which a running platform is mounted, thereby forming a treadmill; characterized in that: a stabilizing support device is provided at the bottom rear side of the running platform, the stabilizing support device comprising: two longitudinal rods, each more than 15cm in length, connected in the middle by a transverse shaft, the two ends of the transverse shaft extending outwards from the outer surfaces of the two longitudinal rods; two bearing seats, which are inverted U-shaped and fitted onto the two ends of the transverse shaft, the top surface of the bearing seats being higher than the two longitudinal rods, and the top surface having at least two connecting holes, which are locked to the bottom of the running platform by two screws, thereby enabling the rear side of the running platform to pivot about the transverse shaft; and at least four feet, respectively mounted on the bottom edge of the ends of the two longitudinal rods, forming a four-foot contact with the ground.

[0007] Based on the aforementioned features, a lifting device may be provided on the front side of the frame at the bottom of the running platform.

[0008] Based on the aforementioned features, the two longitudinal members are in a parallel state.

[0009] Based on the aforementioned features, the width of the two longitudinal members is set to match the width of the running platform.

[0010] Based on the aforementioned features, the foot may include an adjusting bolt located on the bottom edge of the longitudinal member, which can adjust the height of the foot in contact with the ground.

[0011] By utilizing the above-mentioned technical features, this utility model has the following advantages, which need to be further explained:

[0012] I. The stabilizing support device of this utility model has four feet in contact with the ground. Compared with the traditional two-point contact, it makes the treadmill more stable as a whole. Especially when the front end of the running platform 11 forms a high angle, even if someone is running on the running platform and an impact is generated, the four-point contact firmly grips the ground, presenting a stable position. The frame is not easy to shake or make noise, and it can improve the safety during exercise.

[0013] Second, when the four feet of the stabilizing support device of this utility model are in contact with the ground, the rear side of the running platform can pivot around the transverse axis; that is, when the front end of the running platform forms a high angle, the stabilizing support device is completely unaffected and will not change or move with the tilt angle of the front end of the running platform. It still firmly grips the ground with four points of contact, ensuring the safety of the athlete and the comfort of use. Attached Figure Description
