Lifting and folding mechanism for treadmill
A lifting and folding mechanism for treadmill includes a base, a platform, a lifting mechanism, and a linkage mechanism. An armrest rack and a control panel are assembled at the base. A front end of the platform is pivotally assembled with the armrest rack. The lifting mechanism includes a supporting rack and a driving device. One end of the supporting rack is pivotally assembled with the platform, and the driving device is connected between the supporting rack and the platform for driving the supporting rack abutting against the ground, so that the platform is lifted and the slope of the platform is changed. The linkage mechanism is connected to the base and the platform. The linkage mechanism is in a connection state or a disconnection state. In the connection state, the base is connected with the platform, and the base is lifted upward with the lifting of the platform.
