This utility model provides a crankshaft connection structure and a piston air compressor, including a double-sided stop flange, a power take-off sleeve, and a crankshaft body. The double-sided stop flange serves as a common end cover connecting the motor housing and the crankcase. A shaft hole is located at the center of the double-sided stop flange, and the shaft hole is coaxial with the motor rotor. The power take-off sleeve is fixedly inserted through the center of the motor rotor. One end of the crankshaft body is rotatably connected to the end wall of the crankcase away from the motor housing, and the other end extends through the shaft hole into the motor housing to form a power take-off section, which is inserted and fixed to the power take-off sleeve. The portion of the crankshaft body passing through the shaft hole forms a centering section, which is coaxial with the power take-off section and rotatably connected to the shaft hole. The crankshaft connection structure and piston air compressor provided by this utility model allow the crankshaft body to obtain power through the insertion and fixing of the power take-off section and the power take-off sleeve, eliminating the need for a motor shaft and coupling, thus saving axial space and improving the compactness of the overall structure and the flexibility of the installation layout.

This invention discloses a green-environment circulating convection potential energy generator set, belonging to the field of new energy power generation technology. The equipment consists of a pit base, an eccentric acceleration ring, a large and small gear ring transmission assembly, a leverage acceleration wheel, an eccentric speed-up track, a gourd-shaped hammer assembly, an energy water convection cavity, and a cavity-sealed balanced pressure stabilization system. This invention relies on its own structural counterweight and the convection within the sealed energy water system to achieve continuous energy conversion using gravitational potential energy. It does not depend on fossil fuels and is not constrained by wind or photovoltaic power. The overall structure is reasonable, the speed is stable, it is suitable for 5 MW installed capacity, and it can generate electricity continuously for a long period. It solves the defects of traditional generator sets, such as high energy consumption, high pollution, and environmental limitations, and has practical and promotional value.

The utility model belongs to the technical field of workpiece carrying, and particularly relates to a workpiece transferring mechanism. According to the workpiece transfer mechanism, the vertically-arranged belt transmission structure is matched with the swing rod assembly, so that the workpiece transfer mechanism is in efficient transmission in the vertical direction, compared with a traditional swing arm mechanism, the transverse occupied space is greatly reduced, and the workpiece transfer mechanism is suitable for compact production line layout. In addition, a rotary driver is adopted to drive belt transmission, and the mode that the swing rod assembly symmetrically swings is combined, so that the picker keeps a horizontal posture in the moving process, the workpieces are prevented from inclining or falling off, stable reciprocating motion of the picker is achieved, and the picker is suitable for rapid transfer of light and medium-sized workpieces. And compared with a manipulator scheme, the manufacturing cost is remarkably reduced, and meanwhile high carrying efficiency and positioning precision are kept.
