Abstract: The present invention discloses equipment with real-time interactive function and a using method thereof. The equipment is provided with an interactive connection system; an external terminal is connected to the equipment via the interactive connection system, and can directly control the external terminal to open a designated software interface, or directly enables the external terminal to realize a Bluetooth automatic pairing connection with the equipment, thereby reducing the cumbersome procedure of manually opening an APP and the cumbersome procedure of manually connecting the Bluetooth, and saving time, making it convenient and quick. Furthermore, the movement information on the equipment can be obtained through the above-mentioned connection and interaction, and the relevant information can be obtained through a simple and quick connection for subsequent information processing and displaying.

Abstract: A kettle-shaped plastic steel dumbbell comprises a kettle-shaped dumbbell piece and a dumbbell shell molded by injection at the exterior of the dumbbell piece; a handle is fixed on the exterior of the dumbbell shell; a corner sleeve is placed at the joint of the dumbbell shell and the handle; the exterior of the top part of the handle is covered by an anti-slip sleeve; the exterior of the dumbbell piece is covered by a smooth plastic rubber shell, preventing rusts on the dumbbell piece surface overtime which could fall off and damage indoor environment, and avoiding burrs of dumbbell piece surface from puncturing users; anti-slip sleeve with corrugated drain slots is installed on the handle which channels sweat towards both ends of the handle, preventing sweat accumulation from reducing gripping friction and therefore reducing the risk of kettle-shaped dumbbell falling; an elastic component is installed at the bottom of the dumbbell shell to prevent the gravity of the kettle-shaped dumbbell from damaging the
