Treadmill

A treadmill comprising an interaction assembly, a support assembly and a base assembly;

• wherein the interaction assembly is pivotally connected with an upper end of the support assembly such that the interaction assembly can rotate relative to the support assembly and switch between a use state and a non-use state;
• a lower end of the support assembly is pivotally connected with the base assembly such that the support assembly can rotate relative to the base assembly and switch between an unfolding state and a folding state;
• a locking mechanism is provided at a pivot position between the support assembly and the base assembly, the locking mechanism can switch between an active state and a locking state;
• in the active state, the support assembly can rotate relative to the base assembly, and in the locking state, the support assembly cannot rotate relative to the base assembly;
• the treadmill is provided with an operating mechanism, a connecting mechanism and a driving mechanism which are connected sequentially, the operating mechanism is provided on the interaction assembly, the connecting mechanism is provided on the support assembly, the driving mechanism is provided at a pivot position between the support assembly and the base assembly;
• when the interaction assembly is rotated to switch from the use state to the non-use state, the connecting mechanism is driven by the operating mechanism and then the driving mechanism is driven by the connecting mechanism, so as to cause the locking mechanism to switch from the locking state to the active state;
• the locking mechanism comprises a first locking member and a second locking member, the first locking member is provided on the support assembly, the second locking member is provided on the base assembly;
• in the active state, the first locking member is unlocked with the second locking member such that the support assembly can rotate relative to the base assembly;
• in the locking state, the first locking member is locked with the second locking member such that the support assembly cannot rotate relative to the base assembly;
• the first locking member and the second locking member are provided with a concave-convex matching structure;
• in the active state, the first locking member is located far away from the second locking member and the concave-convex matching structure is disengaged from each other such that the first locking member is unlocked with the second locking member;
• in the locking state, the first locking member is located close to the second locking member and the concave-convex matching structure is engaged with each other such that the first locking member is locked with the second locking member.
