Abstract
The utility model discloses a two-dimension coordinate scale, comprising a two-dimension coordinate scale body with graduation, which is is characterized in that: the two-dimension coordinate scale body is a rectangle frame, the graduation is fixed on the edge of the inner frame of the rectangle frame, the a chute surrounding the inner frame is arranged between the inner frame and the external frame, an abscissa scale and an ordinate scale which are orthogonal and has graduation are arranged on the two-dimension coordinate scale body, two ends of the abscissa scale and the ordinate scale has pulleys, the pulleys can move in the chute. The abscissa scale and the ordinate scale of the utility model can move along the chute and can be exactly positioned, thereby conveniently determining coordinates system, drafting points and functional image.
Description
Technical field
The utility model relates to a kind of stationery, specifically is a kind of two-dimensional coordinate chi.
Background technology
The student particularly the high school student when the learning mathematics course, often need to determine coordinate system, accurate described point, make functional image etc., and the student mostly uses two rulers or set square to finish above-mentioned operation at present, obviously, uses ruler or set square not only inconvenient, and accurate inadequately, can not satisfy student's demand.
The utility model content
The purpose of this utility model is to provide a kind of novel two-dimensional coordinate chi, and it can easily be determined coordinate system, described point and do functional image.
The technical scheme in the invention for solving the technical problem is: a kind of two-dimensional coordinate chi, comprise two-dimensional coordinate chi body with scale, it is characterized in that, described two-dimensional coordinate chi body is a rectangle frame, described scale is positioned at the inside casing edge of rectangle frame, has chute between the inside casing of described rectangle frame and the housing around inside casing, also be provided with orthogonal abscissa chi and ordinate chi on the described two-dimensional coordinate chi body with scale, the two ends of described abscissa chi and ordinate chi have pulley, and described pulley can slide in chute.During use, only abscissa chi and ordinate chi just can accurately need be located along the chute slip.
The beneficial effects of the utility model are: abscissa chi of the present utility model and ordinate chi can slide along chute, accurately locate, thereby can easily determine coordinate system, described point and do functional image.
Description of drawings
Fig. 1 is a vertical view of the present utility model.The front view that Fig. 2 laterally cuts open from the chute position for the utility model.
Among the figure: 1 two-dimensional coordinate chi body, 2 chutes, 3 abscissa chis, 4 ordinate chis, 5 scales, 6 pulleys.
The specific embodiment
As shown in Figure 1, a kind of two-dimensional coordinate chi, comprise two-dimensional coordinate chi body 1 and orthogonal abscissa chi 3 and ordinate chi 4 with scale 5 with scale 5, described two-dimensional coordinate chi body 1 is a rectangle frame, described scale 5 is positioned at the inside casing edge of rectangle frame, has the chute 2 around inside casing between the inside casing of described rectangle frame and the housing.
As shown in Figure 2, the two ends of abscissa chi 3 and ordinate chi 4 have pulley 5, and described pulley 5 can 2 slips in chute.During use, only abscissa chi and ordinate chi just can accurately need be located along the chute slip.
