[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See Figures 1-7 A folding mechanism for a treadmill, comprising: a mounting base 1, a positioning rod 3, and a handle 4.

[0024] Mounting base 1 can be installed on the treadmill body 51. It includes a fixing component 11, a connecting base 12, and a movable unit 2. The fixing component 11 can be fixedly installed on the treadmill body 51, and the connecting base 12 can be fixed to the fixing component 11. The two can be welded or integrally formed. The connecting base 12 has a movable hole 121, which can be a through hole or a through circular hole. At the same time, the connecting base 12 also includes a positioning recess 122 with a diameter larger than the movable hole 121. The positioning recess 122 can be formed by recessing inward from one end of the connecting base. Figure 6 As shown.

[0025] The active unit 2 is assembled at the active hole 121, and its shape and size can be consistent with the active hole 121. The end of it near the treadmill body 51 includes a limiting head 21 that matches the positioning notch 122. The shape and size of the limiting head 21 can be consistent with the shape and size of the positioning notch 122. The matching form of the two can be seen in [reference needed]. Figure 4 As shown, when the handle 4 is folded, the wall of the limiting head 21 can abut against the wall of the positioning recess 122, making the movable unit 2 a detachable design to facilitate subsequent maintenance and disassembly and assembly.

[0026] One end of the positioning rod 3 is hinged to the treadmill column 52, and the other end is connected to the moving unit 2. It includes a moving space 31 that moves and cooperates with the moving unit 2. The moving space 31 can be in the form of a through long slot. The moving unit 2 is assembled in the moving space 31. The end of the moving unit 2 away from the treadmill body 51 passes through the moving space 31 and is connected to the handle 4. The handle 4 is rotatably mounted on the moving unit 2.

[0027] The activity space 31 provides the space required for the positioning rod 3 to move when the treadmill column 52 is folded. That is, when the treadmill column 52 is unfolded, the activity unit 2 is close to or against one end of the activity space 31, and when the treadmill column 52 is folded, the activity unit 2 is close to or against the other end of the activity space 31.

[0028] In this embodiment, after the positioning rod 3 is locked, the treadmill column 52 can be limited. Specifically, the handle 4 can be an eccentric handle, which includes an eccentric part 41. Correspondingly, the positioning rod 3 includes a plurality of limiting recesses 32 that cooperate with the handle 4. As one implementation, there are at least two limiting recesses 32, which are located at both ends of the activity space 31, respectively, to limit the treadmill column 52 when it is unfolded and retracted.

[0029] After the treadmill column 52 is unfolded, the handle 4 can be folded. The eccentric part 41 of the handle 4 is inserted into the corresponding limiting notch 32 and the positioning rod 3 is locked. The folding direction of the treadmill column 52 is limited by the handle 4. When folding is required, the handle 4 is unfolded and the eccentric part 41 of the handle 4 can release the limitation on the positioning rod 3.

[0030] Similarly, after folding the treadmill column 52, fold the handle 4 so that the eccentric part of the handle 41 is engaged in the corresponding limiting notch 32.

[0031] To ensure more stable movement of the movable unit 2 on the positioning rod 3, a movable groove 33 communicating with the movable space 31 can be formed on the positioning rod 3. Correspondingly, a second pin 22 that can be assembled into the movable groove 33 is provided on the movable unit 2, with the following mating method: Figure 1 As shown, the second pin 22 can be fixed to the movable unit 2.

[0032] Furthermore, to make the treadmill upright 52 easier to unfold and to provide some damping during folding, a telescopic mechanism 6 can be correspondingly provided on the positioning rod 3. Specifically, a mounting groove 34 connected to the activity space 31 can be opened on the positioning rod 3, and the telescopic mechanism 6 is installed in the mounting groove 34. Figure 5 As shown, furthermore, a first pin 35 is mounted on the positioning rod 3, one end of the telescopic mechanism 6 is fixed to the first pin 35, and the other end is mounted on the movable unit 2.

[0033] As for the way the telescopic mechanism 6 and the movable unit 2 are coupled, as one implementation method, a threaded hole 23 can be opened on the movable unit 2, and the corresponding end of the telescopic mechanism 6 is a threaded end 61. The threaded end 61 is assembled at the threaded hole 23 of the movable unit 2, and the telescopic mechanism 6 can be a gas spring.

[0034] In this embodiment, the treadmill column 52 in the folded and unfolded states corresponds to the movement of the active unit 2 within the activity space 31. Therefore, the telescopic mechanism 6 designed above can provide corresponding auxiliary force when the treadmill column 52 is unfolded and provide corresponding damping when the treadmill column 52 is folded.

[0035] See Figure 1-7 A treadmill includes a treadmill body 51 and treadmill columns 52 symmetrically arranged on both sides of the treadmill body 51. Each treadmill column 52 is equipped with a corresponding folding mechanism. The mounting base 1 of the folding mechanism is mounted on the treadmill body 51, and the positioning rod 3 is hinged to the treadmill column 52. When the handle 4 is folded to limit the positioning rod 3, the treadmill column 52 is rotated and limited relative to the treadmill body 51. For the specific cooperation between the treadmill column 52 and the folding mechanism, please refer to the description above.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
