Abstract
The utility model relates to an ellipsograph with a curved lever and a chute. The utility model comprises a fixed slide carriage having a central shaft, and has the technical proposal that a sliding block is arranged in a chute of the fixed slide carriage. The sliding block and the fixed slide carriage are assembled with a long and a short sliding bars through a rotating shaft and the central shaft, and the long and the short sliding bars are hinged together through a pin shaft. The utility model has the advantages of simple structure and easy fabrication. The utility model can be used for drawing ellipses of various specifications and sizes as general compasses, and the use is quick and convenient.
Description
Technical field
The utility model relates to a kind of drafting instrument, particularly a kind of curved bar chute ellipsograph.
Background technology
At present, the Tuo Yuan technique of painting has many kinds.But generally all be to adopt manual trace-point method, promptly determine respective point earlier, free-hand again by the some line, it promptly bothers, again inaccuracy.And focus backguy method and cross channel process, though the elliptical orbit that can draw in theory but is difficult to practical application.
Summary of the invention
The purpose of this utility model provides a kind of curved bar chute ellipsograph, and it is simple in structure, makes easily, can be as common compasses, and the ellipse of all size that draws, size, quick and easy to use.
The purpose of this utility model is achieved in that this device comprises the fixing slide carriage that has central shaft, its technical essential is: in the chute of fixing slide carriage slide block is arranged, slide block and fixing slide carriage utilize rotating shaft and central shaft to be assembled with long and short slide bar, and long and short slide bar is hinged by bearing pin.
Because the utility model adopts fixing slide carriage and the slide block that is provided with central shaft and rotating shaft, by its upper slide bar and the action of the drawing pin ellipse of all size, size that just can draw quickly and easily, so this apparatus structure is simple, make easily, can use as common compasses, very convenient.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of concrete structure schematic diagram of the present utility model.
The specific embodiment
Describe the concrete structure of the present utility model and the course of work in detail according to Fig. 1.This device comprises the fixing slide carriage 1 that has central shaft 2 and slide block 12, has the short groove 3 of slide bar 4, has the long chute 7 of slide bar 6,9, is installed in picture pin 10 parts such as grade of slide bar 9 ends.Wherein the slide block 12 in fixing slide carriage 1 chute can be along groove to slip, and slide block 12 and fixing slide carriage 1 utilize rotating shaft 8 and central shaft 2 to be assembled with long and short slide bar 7,6, and long and short slide bar 7,6 is hinged by bearing pin 5.Locking pin 11 is set respectively on each slide bar, so that be fixed in the long and short chute, the total length when it connects into straight line is a transverse, and picture pin 10 is an ellipse short shaft to the distance in slide block rotating shaft 8 axle center.
During use, adjust earlier the position of each slide bar, bearing pin 5 is equated with its distance to rotating shaft 8 axle center to the distance in central shaft 2 axle center, transfer oval long and short then, by picture pin 10 ellipse that can draw.
