Coordinate position cognitive learning device for special education

Abstract

The invention discloses a coordinate position cognitive learning device for special education, which comprises a base, a sucker, a rotating seat, a rotating rod, a support frame, a globe, a limiting sleeve, a calibration structure, a calibration frame, a bearing seat, a rotating shaft and a positioning nut, and is characterized in that the bottom of the base is provided with the sucker, and the top side of the base is provided with the rotating seat; the bottom end of the rotating rod is installed in the rotating seat in a matched mode through a bearing, the supporting frame is installed at the top end of the rotating rod, the sponge mat makes contact with the surface of the globe, in the pressing process, the extrusion rod is pushed, the movable pipe is communicated with the flow guide cylinder, the material cylinder is filled with pigment, and the piston is driven by the piston to rotate under the cooperation of the reset spring. After the sealing cap is separated from the end opening of the movable pipe, the pigment flows downwards along the movable pipe to dip and dye a sponge mat, marking of coordinates can be achieved, multi-point marking can be achieved, direct connection display can be achieved after marking, and the position of the coordinates can be recognized more visually.

Description

technical field [0001] The invention relates to the technical field of coordinate learning, in particular to a coordinate position cognitive learner for special education. Background technique [0002] A spherical coordinate system established on the celestial sphere to determine the position of a point on the celestial sphere. There are two basic elements: the basic plane, determined by a selected great circle on the celestial sphere, called the base circle, one of the two geometric poles of the base circle, as the pole of the spherical coordinate system, and the principal point, also known as the origin , determined by the intersection of a selected great circle passing through the pole of the coordinate system on the celestial sphere and the base circle; [0003] Globes are used to facilitate the understanding of the earth. People imitate the shape of the earth, shrink it according to a certain ratio, and make a globe. There are length, area, direction, and shape deforma...

Problems solved by technology

[0005] The object of the present invention is to provide a special education coordinate position cognitive learner, which solves the problem of not being able to intuitively mark the coordinates when marking. Knowing the time, unable to calibrate accurately, unable to rotate during the learning process, technical problems of multi-directional observation of the globe
