Description

Technical Field

[0001] The utility model relates to the technical field of treadmills, in particular to a panel folding structure of a treadmill. Background Art

[0002] The treadmill is a common indoor fitness equipment, widely used in homes and gyms. It simulates running and walking and is a full-body aerobic exercise. The running area, preset programs, safety, panel design, and motor performance of the treadmill are all factors that need to be considered when choosing a treadmill. Among them, in order to facilitate the user's use of the panel, the panel is generally designed to be a foldable structure.

[0003] In the prior art, the folding between the panel and the handrail is usually done by a set of threaded bolts and nuts as the axis. After the bolts are tightened, the purpose of locking the rotating shaft can be achieved, thereby fixing the angle of the panel. The user needs to use a large force to bend the panel to change its angle direction. This structure is relatively simple and easy to assemble, but the functional stability is low because with multiple angle adjustments of the panel, the nuts are easy to loosen, resulting in the panel being unable to be fixed at a specific angle.

[0007] The first pivot seat and the second pivot seat are both U-shaped parts; the first pivot seat is provided with the first through hole on both wings, and the second pivot seat is provided with the second through hole and the third through hole on both wings; the second pivot seat is located on the outer sides of the first pivot seat, respectively, and the shaft of the rotating shaft passes through the third through hole, the two first through holes and then out of the second through hole in sequence.

[0008] Preferably, damping gaskets are provided between the two wings of the second pivot seat and the two wings of the first pivot seat.

[0009] Preferably, a rotating tube is provided between the two wings of the first pivot seat, two ends of the rotating tube are respectively fitted in the two first through holes, and the shaft portion of the rotating shaft is movably inserted into the rotating tube.

[0010] A flat washer is arranged between the second pivot seat and the nut.

[0011] After adopting the above technical solution, the utility model has the following technical effects:

[0012] The utility model designs the first limiting surface and the second limiting surface on the second through-hole and the shaft portion respectively, so that the rotating shaft and the second pivot seat maintain a synchronous rotation state, that is, the rotating shaft and the second pivot seat are relatively stationary. When the user adjusts the angle of the movable plate fixed relatively to the second pivot seat, the rotating shaft and the nut are always relatively stationary with the second pivot seat, which will not cause the nut to loosen, thereby ensuring the stability of the overall structure.
