Utility model content
For the deficiencies in the prior art, the utility model provides a kind of Coordinate chi, utilizes this coordinatometer can determine the position of each coordinate points fast and accurately in rectangular coordinate system and non-orthogonal coordinate system.
The utility model realizes above-mentioned technical purpose by following technological means.
A kind of Coordinate chi, comprises fixed ruler, adjustable rule, connector and slide block; Described fixed ruler and adjustable rule are in same plane and be equipped with scale, and long limit with a scale on described fixed ruler is that linear contact lay or face contact with the minor face near initial point on adjustable rule; The upper surface of described fixed ruler offers the first chute matched with slide block; Described connector is positioned at the top of slide block and adjustable rule, and one end that connector is connected with adjustable rule is provided with strip through hole; One end of described connector is by the first screw connection sliding block, and the other end connects adjustable rule by the second screw being positioned at strip through hole.
Further, the outer side surface of described fixed ruler also offers the second chute; Match with the first chute in one end of described slide block, the other end matches with the second chute.
Further, the shape of described strip through hole is oval or rectangle.
Further, the two ends of described fixed ruler are provided with locating pin.
Further, one end that described connector is connected with slide block is provided with angle index.
Further, on described second screw, cover has spring.
The beneficial effects of the utility model:
Coordinate chi described in the utility model, by arranging fixed ruler, adjustable rule, connector and slide block, fixed ruler and adjustable rule can be turned by connector and slide block have a certain degree, in rectangular coordinate system and non-orthogonal coordinate system, all fast, accurately can read each point coordinate; By offering the first chute and the second chute at the upper surface of fixed ruler and outer side surface, two chute improves the precision of skid; Locating pin is set at the two ends of fixed ruler, fixed ruler is fixed on paper, facilitates follow-up surveying work; The one end be connected with slide block at connector is marked with angle index, improves the degree of accuracy of fixed ruler and adjustable rule rotational angle; On the second screw, cover has a spring, for adjusting the gap between adjustable rule and fixed ruler, makes adjustable rule concordant with fixed ruler bottom surface.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, but protection domain of the present utility model is not limited to this.
As depicted in figs. 1 and 2, a kind of Coordinate chi, comprises fixed ruler 1, adjustable rule 2, connector 3 and slide block 4; Described fixed ruler 1 and adjustable rule 2 are equipped with scale, and long limit with a scale on fixed ruler 1 is that linear contact lay or face contact with the minor face near initial point on adjustable rule 2, and both are in same level; Being face contact each other when being applied in rectangular coordinate system, is linear contact lay between the two when being applied in non-orthogonal coordinate system; Both sides with a scale form two coordinate axis of two-dimensional coordinate system jointly.The upper surface of described fixed ruler 1 and outer side surface offer the first chute 8 and the second chute 9 respectively, match with the first chute 8 in one end of described slide block 4, the other end matches with the second chute 9, slide block 4 can slide along the first chute 8 and the second chute 9, and two chute improves the degree of accuracy that slide block 4 slides.
Described connector 3 is positioned at the top of slide block 4 and adjustable rule 2, and one end of connector 3 is by the first screw 5 connection sliding block 4, makes connector 3 and slide block 4 with the first screw 5 for axle relatively rotates; One end that connector 3 is connected with adjustable rule 2 is provided with strip through hole, and this through hole can be oval or rectangular through-hole, and making between adjustable rule 2 and connector 3 can relative movement, to adapt to origin position and the angle angle of different coordinate axis.The rotation between adjustable rule 2 and fixed ruler 1 is realized by the rotation between connector 3 and slide block 4.The two ends of fixed ruler 1 are provided with locating pin 7, and one end that described connector 3 is connected with slide block 4 is provided with angle index, and on described second screw 6, cover has spring, for adjusting play, makes adjustable rule concordant with fixed ruler bottom surface.
The course of work: as shown in Figure 3, when using coordinatometer reading described in the utility model, first a coordinate axis with graduated long edge image on fixed ruler 1 is put well, its initial point is overlapped with the true origin of image, now locating pin 7 is pressed, make toply to be fixed in paper; Regulate the position of adjustable rule 2 and fixed ruler 1, both adjustments are become angle needed for coordinate axis; Unscrew the second screw 6, the position of adjustment adjustable rule 2 and connector 3, makes the initial point of adjustable rule 2 overlap with coordinate axis initial point, after end to be adjusted, the first screw 5 and the second screw 6 is screwed, can obtain the coordinatometer matched with this coordinate axis simultaneously.During measurement, slide up and down arbitrary coordinate point place in coordinate system by slide block 4, draw the coordinate of coordinate points to be measured according to the scale value on fixed ruler 1 and adjustable rule 2.
When using this coordinatometer to draw scatter diagram, fixed ruler 1 is fixing on paper by locating pin 7, draw as transverse axis or the longitudinal axis, determine true origin; Adjust adjustable rule 2 and fixed ruler 1 and the position with connector 3 simultaneously, draw another coordinate axis, in conjunction with coordinate axis scale and in coordinate system, get to data put and complete the drafting of image.
