Abstract
The utility model discloses a multifunctional teaching tool for teaching and relates to a teaching tool for teaching. The multifunctional teaching tool for teaching aims at solving the problems that in the prior art, a compass for drawing circles and a teaching tool for drawing angles are not combined so that a teacher need a plurality of different types of teaching tools in a teaching process, use is not convenient and teaching quality is affected. A rectangular through hole is arranged in the middle of a horizontal ruler board of a right-angle ruler along the length direction, a chalk sleeve is arranged in the rectangular through hole and closely matched with the rectangular through hole, and the chalk sleeve can slide back and forth along the rectangular through hole under the function of external force. An adjusting knob for adjusting extended length of chalk in the chalk sleeve is arranged on the chalk sleeve, the other end of a rotating shaft is inserted into a blind hole of a sucking disc and can achieve self rotation along the sucking disc, a right triangle ruler is in the same plane with the right-angle ruler, and one right-angle side of the right triangle ruler is connected with the outer side of a vertical ruler board of the right-angle ruler. The multifunctional teaching tool for teaching is simple in structure, capable of reducing types and amount of teaching tools used by the teacher in the teaching process, and is convenient to use in teaching.
Description
Technical field
The utility model relates to a kind of teaching aid.
Background technology
At present, in natural science or mathematics primary school teaching process, often need teacher to draw some geometric figures, for example right angle, circle or other shape at blackboard.Various teaching aids also are provided in the prior art, have not combined with compasses and the teaching aid of drawing the angle but will draw circle in the prior art, caused teacher in teaching process, needed the teaching aid of number of different types, be easy to use, affected quality of instruction.
The utility model content
The utility model combines in order to solve will not draw in the prior art to justify with compasses and the teaching aid of drawing the angle, cause teacher in teaching process, need the teaching aid of number of different types, use inconvenience, affect the problem of quality of instruction, and then a kind of teaching Multifunctional teaching aid is provided.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be:
Teaching described in the utility model comprises square, adjusting knob, chalk sleeve, rotating shaft, sucker and right angled triangle chi with Multifunctional teaching aid; The horizon rule plate middle part of square is provided with the strip through hole along its length direction, and chalk sleeve is installed in the described strip through hole and with the strip through hole and closely cooperates, and chalk sleeve can slidably reciprocate along described strip through hole under external force; Chalk sleeve is provided with for the adjusting knob of regulating chalk extension elongation in the chalk sleeve, and an end end face of rotating shaft is fixed in an end of square and is positioned at the place at zero point of the lower surface of horizon rule plate, and the other end of rotating shaft inserts in the blind hole of sucker and can be along the sucker rotation; Right angled triangle chi and square are in same plane, and a right-angle side of right angled triangle chi is connected with the lateral surface of the miter square plate of square.
The beneficial effects of the utility model are:
Teaching aid provided by the utility model will be drawn round function with compasses and angle square and integrate, the function of have the picture circle, drawing right angle, other acute angles and some common geometry figures; Be simple in structure and convenient in use.Reduce teacher in teaching process, use kind and the quantity of teaching aid, convenient teaching is improved the quality of teaching.The utility model is used for primary school teaching.
