The utility model discloses a
treadmill, and belongs to the technical field of treadmills. According to the
treadmill, the stand columns and the
treadmill table are movably connected through the transversely-arranged rotary supporting assemblies, so that the stand columns can be switched between the unfolded state and the folded state, and transverse limiting of the stand columns can be achieved. By longitudinally arranging the unfolding locking
assembly, the stand column can make contact with the stand column limiting piece after being unfolded, the limiting locking part on the stand column is fixedly connected with the stand column limiting piece through the locking piece, longitudinal locking force is provided for the stand column, the stability of the stand column in the unfolded use state is effectively guaranteed, the stand column is not prone to shaking, and the service life of the stand column is prolonged. Therefore, the use experience of the user is improved. In addition, the unfolding and locking
assembly is simple in structure, and the manufacturing cost of the treadmill is saved.
