Abstract: A folding structure for treadmill handle bar, including a handle bar foldable against a supporting post, and also a position limiting member and a reset member, where a first pivotal piece is provided on a top end of the supporting post; at least two position limiting grooves are formed on the first pivotal piece; a second pivotal piece is provided at an end portion of the handle bar; the first and second pivotal pieces are coaxial; the positioning limiting member is pivotally connected to the second pivotal piece and vertical aligned with the first pivotal piece; the position limiting member has a driver part and a protrusion engageable with the position limiting grooves; and the reset member is connected with the handle bar and the position limiting piece.

Abstract: A lifting mechanism for gym equipment to provide height adjustment of the gym equipment and reduction of the thickness of the mechanism, having a bracket, a bearing rotational shaft, bearing wheels, a sleeve pipe, and a driver; the bracket is mounted to a gym equipment structural frame; the bearing rotational shaft is rotationally mounted between two ends of the bracket, a peripheral surface of the bearing rotational shaft is connected to linkage arms orienting to a same direction, and a wheel is mounted to each linkage arm; the sleeve pipe is pivotally connected to the bracket; the driver is pivotally connected to the bracket; an output end of the driver is a screw bolt; the screw bolt passes through the sleeve pipe.

Abstract: A foldable treadmill having a base and a rotational shaft whose two ends are fixed with supporting posts respectively; handle bars are mounted to top ends of the supporting posts respectively; two seats are fixed on the rotational shaft and correspond to the support posts; one end of each wire is connected with a corresponding handle bar, another end of each wire is connected with a corresponding pin; rotation of the handle bars to achieve folding of the treadmill drives the wires to pull the pins; each seat has a position limiting hole which a corresponding pin is removably inserted, so that the two seats together with the rotational shaft achieve a fixed state or a rotatable state with respect to the base.

Abstract: A microfluidic electrochemical device and process are detailed that provide chemical imaging and electrochemical analysis under vacuum at the surface of the electrode-sample or electrode-liquid interface in-situ. The electrochemical device allows investigation of various surface layers including diffuse layers at selected depths populated with, e.g., adsorbed molecules in which chemical transformation in electrolyte solutions occurs.
