A hand movement display device for climbing teaching

Abstract

The invention relates to a climbing teaching hand movement display device comprising a double-layer frame. A motor is mounted on the lower portion of the double-layer frame and connected with an incomplete gear, the front side and the rear side of the incomplete gear are provided with spur gears matched with the incomplete gear in a meshed mode, and the upper end face of each spur gear is providedwith a bump at the eccentric position. The front side and rear side of the upper portion of the double-layer frame are provided with dovetail grooves, a vertical rod is slidably mounted in each dovetail groove, a cross rod is welded to the lower end of each vertical rod, and each cross rod is provided with a horizontal groove for horizontally slidably mounting the bump. The climbing teaching handmovement display device is high in automation degree, two small arm rods are controlled in a gear tooth meshing mode to climb upwards alternately, on the basis, a shoulder rod can also be driven automatically to rise after the climbing of the two small arm rods, so that arm action during the approximate simulation display of continuous climbing is achieved, and the climbing teaching hand movementdisplay device has a good teaching display effect.
