Description
Technical field
The utility model relates to a kind of drawing instrument, especially a kind of ellipsograph.
Background technology
Known: engineers and technicians, when carrying out ellipse drawing, can be applied to ellipsograph, but traditional ellipsograph, major axis and minor axis cannot carry out linear regulation, and therefore the ellipse of some size cannot be drawn accurately.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of can the ellipsograph of linear regulation transverse and minor axis dimension.
The utility model solves the technical scheme that its technical problem adopts: ellipsograph, comprises pedestal, balladeur train, ruler, the first adjusting device, the second adjusting device, slide bar, the first slide block, the second slide block;
Described pedestal is provided with orthogonal first chute and the second chute; Described first slide block is arranged in the first chute, and described second slide block is arranged in the second chute; Described balladeur train one end and the first slide block hinged; Described balladeur train is provided with chute, and described sliding bar is arranged in chute, and hinged with the second slide block; Described slide bar regulates the position of slide bar on balladeur train by the second adjusting device; Described ruler is slidably mounted on balladeur train by the first adjusting device.
Further, described ruler one end is provided with paintbrush installing hole.
Further, described first adjusting device comprises adjustment screw; The upper surface of described balladeur train is provided with boss, described boss is provided with ruler chute; Described ruler is slidably mounted in ruler chute, and described adjustment screw by extending through above boss in ruler chute, and contacts with the upper surface of ruler.
Further, described second adjusting device comprises adjusting nut and regulating shaft; Described balladeur train side is provided with the adjustment chute being communicated with chute, and described regulating shaft is fixedly connected with slide bar through regulating chute one end; The other end extends to balladeur train side, and coordinates with adjusting nut.
The beneficial effects of the utility model are: ellipsograph described in the utility model, because ruler is slidably mounted on balladeur train, therefore can regulate the length of ruler, thus realize regulating the dimension linearity of ellipse short shaft.Simultaneously one end of balladeur train is provided with slide bar, and sliding bar is arranged on balladeur train, by the linear regulation regulating the position of slide bar on balladeur train and the position of ruler on balladeur train can realize the size of transverse.Therefore the ellipsograph described in this practicality can draw the ellipse of different minor axis and major axis accurately, improves drafting accuracy.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As Figure 1-3, ellipsograph described in the utility model, comprises pedestal 1, balladeur train 2, ruler 3, first adjusting device 4, second adjusting device 5, slide bar 6, first slide block 71, second slide block 72;
Described pedestal 1 is provided with orthogonal first chute 11 and the second chute 12; Described first slide block 71 is arranged in the first chute 11, and described second slide block 72 is arranged in the second chute 12; Described balladeur train 2 one end and the first slide block 71 hinged; Described balladeur train 2 is provided with chute, and described slide bar 6 is slidably mounted in chute 2, and hinged with the second slide block 72; Described slide bar 6 regulates the position of slide bar 6 on balladeur train 2 by the second adjusting device 5; Described ruler 3 is slidably mounted on balladeur train 2 by the first adjusting device 4.
In the process used, carry out the major axis of the ellipse drawn and the size of minor axis first as required, respectively the position on balladeur train 2 of ruler 3 and the position of slide bar 6 on balladeur train 2 are regulated.First by regulate ruler 3 position adjustments minor axis length, then fix ruler 3 by the first adjusting device 4; The position of slide bar 6 on balladeur train 2 is regulated again by the second adjusting device 5; Because ruler 3 and slide bar 6 are all slidably mounted on balladeur train 2, therefore all linear regulation can be realized; Thus realize the linear regulation of transverse and minor axis dimension.After adjustment completes, ellipsograph is placed on paper, determines center, the top of paintbrush being placed ruler 3 is followed ruler 3 and is rotated, and can complete oval drafting.
In sum, ellipsograph described in the utility model, because ruler 3 is slidably mounted on balladeur train 2, therefore can regulate the length of ruler 3, thus realizes regulating the dimension linearity of ellipse short shaft.Simultaneously one end of balladeur train 2 is provided with slide bar 6, and slide bar sliding 6 is dynamic to be arranged on balladeur train, by the linear regulation regulating the position of slide bar 6 on balladeur train 2 and the position of ruler 3 on balladeur train 2 can realize the size of transverse.Therefore the ellipsograph described in this practicality can draw the ellipse of different minor axis and major axis accurately, improves drafting accuracy.
Installation for the ease of paintbrush is located, and further, described ruler 3 one end is provided with paintbrush installing hole 31.
For the ease of the adjustment of ruler 3 horizontal length, further, described first adjusting device 4 comprises adjustment screw; The upper surface of described balladeur train 2 is provided with boss, described boss is provided with ruler chute; Described ruler 3 is slidably mounted in ruler chute, and described adjustment screw by extending through above boss in ruler chute, and contacts with the upper surface of ruler 3.
For the ease of the position adjustments of slide bar 6, further, described second adjusting device 5 comprises adjusting nut and regulating shaft; Described balladeur train 2 side is provided with the adjustment chute being communicated with chute, and described regulating shaft is fixedly connected with slide bar 6 through regulating chute one end; The other end extends to balladeur train 2 side, and coordinates with adjusting nut.
