DETAILED DESCRIPTION

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0022] like Figures 1 to 7 As shown, a folding treadmill includes a bottom frame 1, a middle support 5, a running platform frame 4, and an elastic element 7. One end of the middle support 5 is slidably connected to the bottom frame 1, and a connecting rod 6 is provided between the middle support 5 and the bottom frame 1. The two ends of the connecting rod 6 are respectively hinged to the middle support 5 and the bottom frame 1. A third connecting bracket 5a is provided on the middle support 5, and one end of the elastic element 7 is hinged to the third connecting bracket 5a, while the other end of the elastic element 7 is hinged to the bottom frame 1. The running platform frame 4 is disposed on the middle support 5.

[0023] The bottom frame 1 is provided with a column 2, and the upper end of the column 2 is rotatably connected to a handrail 3. A locking mechanism is provided between the handrail 3 and the column 2. When the locking mechanism is in the unlocked state, the handrail 3 can be flipped up and down.

[0024] In this invention, the running platform frame 4 can be flipped up and down. When the treadmill is in use, the running platform frame 4 is flipped down to a near-horizontal state (e.g., ...). Figure 1 As shown), when the treadmill is in the folded state, the running platform frame 4 flips up to a vertical position relative to the ground (as shown). Figure 6 As shown), during the upward folding process of the treadmill frame 4, one end of the middle support 5 will slide along the bottom frame 1; during the folding process, the presence of the elastic element 7 will provide some assistance to the upward folding of the treadmill frame 4, facilitating the folding of the treadmill frame 4. Since control panels and other equipment will be installed on the handrail 3, in order to avoid interference between the treadmill frame 4 and the handrail 3 when the treadmill frame 4 is folded up to be vertical to the ground, the handrail 3 in this utility model is also designed as a foldable structure; when the treadmill needs to be folded, first unlock the locking mechanism, and then fold the handrail 3 up to be perpendicular to the ground (as shown). Figure 6 (As shown), and then the running platform frame 4 is folded upwards.

[0025] In this invention, the running platform frame 4 can be folded at 90 degrees (i.e., the running platform frame 4 is perpendicular to the ground), thereby effectively reducing the indoor space occupied by the treadmill, especially reducing the occupation of the indoor horizontal space, and has good storage capacity.

[0026] The folding structure and folding mode in the utility model can compress the height difference between the running track frame 4 and the bottom frame 1 to the maximum extent when the running track frame 4 is in the unfolded state, so that the running track frame 4 is closer to the bottom frame 1, thereby reducing the ground clearance of the running track frame 4 and facilitating the reduction of the packaging size and the reduction of the packaging cost.

[0027] The locking mechanism comprises a fixing member 11 arranged on the handrail 3, a locking screw 12 threadedly connected to the fixing member 11, and a locking hole 2a arranged on the stand 2 and corresponding to the locking screw 12. When the treadmill is in use, the handrail 3 is locked by the locking mechanism, and at this time, the locking screw 12 is rotated to extend into the locking hole 2a, so as to fix the handrail 3 and prevent the handrail 3 from rotating. When the treadmill needs to be folded, the locking mechanism is unlocked, and the locking screw 12 is rotated to withdraw from the locking hole 2a, so that the handrail 3 can be rotated and folded.

[0028] The bottom frame 1 is provided with a sliding groove 1a on each side thereof, and the middle support 5 is provided with a roller 5b on each side of one end thereof, and the roller 5b is connected to the sliding groove 1a and can move along the sliding groove 1a.

[0029] In the embodiment, the elastic member 7 is a gas spring. In addition, the elastic member 7 can also be a hydraulic prop or other types of elastic members 7, which can be selected according to actual needs.

[0030] Further, the running track frame 4 is provided with a first connecting support 4a, the running track frame 4 is hinged to the bottom frame 1 through the first connecting support 4a, an adjusting member is arranged between the running track frame 4 and the bottom frame 1, the length of the adjusting member is adjustable, one end of the adjusting member is hinged to a third connecting support 5a on the middle support 5, and the other end of the adjusting member is hinged to a second connecting support 4b arranged on the running track frame 4.

[0031] The adjusting member comprises a motor 8 and a threaded sleeve 10, the motor 8 is hinged to the second connecting support 4b, a lead screw 9 is connected to the motor 8, the lead screw 9 is threadedly connected to the threaded sleeve 10, and the threaded sleeve 10 is hinged to the third connecting support 5a. The adjusting member is used for adjusting the inclination angle between the running track frame 4 and the ground. During adjustment, the motor 8 drives the lead screw 9 to rotate, and the overall length of the adjusting member is adjusted through the rotation of the lead screw 9, so as to change the angle of the running track frame 4.

[0032] The utility model is not limited to the above best implementation, and any person can draw other various forms of products under the enlightenment of the utility model, but no matter any change in its shape or structure, all the technical schemes with same or similar to the application fall in the protection scope of the utility model.
