A mechanical flying bird demonstration device

Abstract

A mechanical flying bird demonstration device, related to the field of science and education, comprising: vertical beams, the vertical beams are provided with two, the upper part of the two vertical beams is erected with a crossbeam, the lower part of the crossbeam is fixed with a pull rod, and the lower end of the pull rod is installed with a suspension Axle seat; crankshaft, the crankshaft is installed on the suspension axle seat, and the two ends of the crankshaft extend into the vertical beams on both sides respectively, and a drive motor is installed inside the vertical beam, and the drive motor provides power for the crankshaft; An action drive mechanism is installed on the crankshaft, a traction rope is connected to the action drive mechanism, and a bird is connected to the lower end of the traction rope. By suspending the traction rope on the crankshaft, the traction rope suspends the flying bird, and when the crankshaft rotates, the traction rope is pulled to move up and down, so that the flying bird floats up and down, which is convenient for observing the flying and floating attitude of the flying bird.

Description

Technical field [0001] The present invention relates to the field of science and education, and specific relates to a mechanical bird flying presentation device. Background technique [0002] The mechanical structure is widely used in production and life, in order to meet the needs of the laboratory and the science panel, let learners and viewers can learn from the mechanical movements and use, and study some specific mechanical models is necessary. [0003] The birds are standing in the ground, the wings are fanned downwards, the direction is the same as the geostational direction, due to inertia, the air under the wings will not immediately follow the wings down, so the air pressure under the wings will rise, and due to inertia, the upper part of the wings The air will not immediately follow the wings down, so the pressure on the upper part of the wings will decrease, so there is a pressure difference in the wings, this pressure is flying upward. In order to make it more conven...
