Abstract
Coordinate exhibition point chi is the specialized tool in survey and drawing field, comprises main chi frame and slide rule, is provided with a slide rule in the main chi frame or is provided with two slide rules with vertically crossing, during the use, only needs X, Y coordinate value according to the demand exhibition point to remove the slide rule, just can accurately accomplish coordinate exhibition point location rapidly, and characteristics are: novel structure, and is quick and convenient to use.
Description
The utility model is the specific purpose tool of survey field.
When drawing in mapping operations, it is coordinates extention that a large amount of work is arranged, and coordinates extention is exactly the coordinate data that measurement gets to be dwindled according to a certain percentage and definite this correspondence position on drawing.At present, the instrument that uses of coordinates extention is used as general utility tools such as engineer's scale, set squares.During use, each coordinates extention all needs 2 to 4 amounts, draw and just to determine the position of putting, and is very inconvenient.
The purpose of this utility model is to provide a kind of quick coordinates extention chi of using when charting of surveying and drawing, and finishes the coordinates extention location quickly and accurately with it.
To achieve these goals, quick coordinates extention chi of the present utility model, form by main scale frame and slide rule, the central authorities of main scale frame for the coordinate grid (square opening of 100mm * 100mm) match, and on the framework of main scale frame, have relative a pair of or two pairs of chutes, slide rule is one or is two that square crossing ground is arranged that slide rule is contained in the chute of framework across its two ends of main scale frame.On the main scale edge and slide rule be marked with scale graduation, be to adopt stainless steel, celluloid, copper or other to be subjected to temperature to influence the very little material of distortion to make.
During use, the main scale frame is placed on the corresponding coordinate grid identically, the rectangular co-ordinate value of machine plotting and the reduce in scale that needs move slide rule with reference to scale according to demand, just can determine the machine plotting position rapidly.
Characteristics of the present utility model are: novel structure, during use not only fast but also convenient.
Further narrate below in conjunction with accompanying drawing.
Fig. 1 is the coordinate machine plotting chi structural representation with two slide rules;
Fig. 2 is the coordinate machine plotting chi structural representation that has only a slide rule;
Among the figure: the horizontal slide rule of the vertical slide rule 3--of 1--main scale frame 2--
Embodiment 1, referring to Fig. 1, main scale frame 1 vertical slide rule 2 and horizontal slide rule 3 are all made with the celluloid material, main scale frame central authorities have the square opening of 100mm * 100mm, the framework inboard of main scale frame has two pairs of relative chutes, the cross section of every pair of chute is swallow-tail form, the two ends of slide rule also make dovetail shaped, the length of slide rule can be as the criterion to be contained in the chute in driving fit, slide rule wide with greater than 15mm for well, when being pushed, do parallel moving to guarantee slide rule, main scale upper frame edge target scale graduation is a basis of reference, and vertically slide rule is the same with horizontal slide rule structure, and scale graduation is carved with on the surface, two slide rules are provided with by square crossing ground in the main scale frame, all do parallel moving after being pushed.Slide rule can be changed, so that select the scale graduation that needs for use.
Embodiment 2, referring to Fig. 2, main scale frame 1 and vertical slide rule 2 are all made with stainless steel material, all indicate 1:1000 commonly used on the main scale frame He on the slide rule, 1:500, three kinds of scale graduations such as 1:2500, present embodiment is the reduced form of embodiment 1, its physical dimension is all the same with last example, but only establishes a vertical slide rule.
