The invention discloses a flapping wing driving mechanism for science and teaching demonstration. The mechanism is composed of a rack, a speed reducing motor and an adjustable crank and rocker mechanism; and the rack is fixedly provided with the speed reducing motor by which the adjustable crank and rocker mechanism is driven to flap up and down at a certain frequency and amplitude. The flapping wing driving mechanism is compact in structure, simple in operation and capable of vividly and intuitively showing a flapping wing flapping way and greatly enriching the interestingness of science andteaching demonstration, and both the flapping frequency and flapping amplitude of the driving mechanism can be adjusted within a certain range.

This patent discloses a dynamic and variable parabola experimental instrument, which is mainly composed of a flat square box for holding water, a motor, a power supply, a table and a mobile phone. Fixed in the groove of the turntable, one end of a lightweight straight rod is perpendicular to the water flat square box and fixed on the plastic turntable, and the other end fixes the mobile phone; the water flat square box is made of transparent resin board with holes on the top Flat square box, one side of the flat square box for water is engraved with a grid, put a certain amount of water and a little dyed kerosene into the flat square box for water, and insert a rubber plug into the hole of the square box to seal the flat square box for water; The water flat square box and the mobile phone rotate together with the motor at the same angular speed, and the liquid level in the water flat square box at the corresponding speed can be observed to explore the parabolic equation. The manufacturing cost is low, the production is easy, and the effect is obvious.

The invention discloses an ornithopter flapping wing driving mechanism for science and education demonstration, and belongs to the technical field of the science and education demonstration. The ornithopter flapping wing driving mechanism comprises a machine frame and a motional assembly mounted on the machine frame, wherein the motional assembly comprises a speed-reducing motor, a shaft coupler and an adjustable crank and rocker mechanism; the speed-reducing motor drives the adjustable crank and rocker mechanism to move through the shaft coupler; the adjustable crank and rocker mechanism comprises an adjustable crank and a pair of rocker assemblies; the adjustable crank comprises a transmission shaft, a crank, a slide block and an adjusting screw rod; the adjusting screw rod runs througha crank threaded hole and a slide block threaded hole in a screwing manner so as to limit the slide block in a strip-shaped sliding slot; each rocker assembly comprises a connecting rod and a rocker arm; the middle parts of the rocker arms are hinged to the machine frame through rotating shafts; the lower ends of the connecting rods are hinged to a short shaft of the adjustable crank; the upper ends of the connecting rod are hinged to the inner ends of the rocker arm. The ornithopter flapping wing driving mechanism has the characteristics of a long service life, convenience and safety in operation, simpleness, easy understanding, strong enlightenment, suitability for popularization and the like.
