Abstract
The utility model discloses an ellipsograph, which is characterized in that: the utility model is provided with a base, and the base is provided with two runners in a cross; the two runners are provided respectively with a sliding block which slides at the respective runner; each sliding block is provided with a vernier card which protrudes out of the runner, and can slide following the sliding block and rotate at the sliding block; the two vernier cards are fixed at different positions of the verniers according to the size of the long and short shaft of the ellipsograph, and one end of the ruler is fixed at a pen frame. The utility model has convenient use, accurate drawing, good repetitiveness, large adjustable scale of size, thus can be used extensively for school implements and general utility tools.
Description
The utility model relates to drawing instrument, more particularly, is a kind of oval ellipsograph that is used for drawing.
Up to now, all there is not to be used for directly drawing out oval instrument both at home and abroad.Though draw oval method drawing accurately according to graphing method, very time-consuming.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, provides a kind of and can directly draw out oval ellipsograph.
The purpose of this utility model is achieved through the following technical solutions:
Design feature of the present utility model is that a base is arranged, and the twice chute is arranged on base, and the twice chute is " ten " word and intersects; In the twice chute, a slide block that slides is arranged respectively in slideway separately; On each slide block, protrude from outside the slideway, be provided with the vernier card that can slide with slide block, also can rotate on slide block, two vernier cards are pressed the fastening of oval long and short shaft size difference on the diverse location of scale, scale one end dead knife penholder.
The utility model has the advantages that easy to use, map accurate, good reproducibility, the size adjustable scope is big.The utility model can be widely used as and be teaching appliance, general utility tool etc.
Fig. 1 is the utility model structural representation.
Fig. 2 clamps the distribution structure schematic diagram for the utility model slide block and vernier.
By the following examples, in conjunction with the accompanying drawings the utility model is further described.
Embodiment:
Referring to accompanying drawing, a base 1 is arranged in the present embodiment, twice chute 2,3 is arranged on base 1, comprise chute A2 and chute B3, chute A2 is " ten " word with chute B3 and intersects, and constitutes horizontal coordinate.In the twice chute 2,3, a slide block A4 who slides and slide block B 5 are arranged respectively in slideway separately; On each slide block, protrude from outside the slideway, be provided with the vernier card 6,7 that can slide with slide block, also can on slide block, rotate, comprise vernier card A6 and vernier card B7.Two vernier cards are pressed the fastening of oval long and short shaft size difference on the diverse location of vernier 8, vernier 8 one end dead knife penholders 9.
Two slide blocks 4,5 can be set to the strip that coincide with chute 2,3 in order to improve precision, two chutes are positioned on the different aspects of base.The strip slide block can intersect slip in the chute of different aspects.
In addition, at vernier card 6,7, and on the writing of indictments, appeals, etc. frame 9, be respectively arranged with shop bolt 10.
In concrete the enforcement, should be equipped with base plate 11.Bottom at base 1 is provided with angle, on the base plate 11 of correspondence position, locating hole is arranged.
During use, at first, adjust vernier by the oval long and short shaft size of draw and be stuck in position on the scale, wherein, vernier card is set at major axis apart from the distance of writing of indictments, appeals, etc. frame nib, and then another vernier card promptly is set at minor axis apart from the distance of writing of indictments, appeals, etc. frame nib.After adjustment is finished, lock by shop bolt.Drawing paper is laid on the base plate of base below.Rotary scale, two slide blocks slide in chute separately respectively, and in the sliding process, vernier is stuck on the slide block and rotates.Scale turns over complete cycle, and the track that its end nib is streaked on paper is the ellipse of required size.
