Abstract
The utility model discloses a combined drawing instrument, mainly comprising a T-square and an angle measuring ruler; the T-square (1) is connected with the angle measuring ruler (4) through a positioner (2); the positioner (2) can drive the angle measuring ruler to move rightwards and leftwards on the T-square; the angle measuring ruler can rotate around the positioner. The utility model has the advantages of convenient operation, simple structure and low cost and can conveniently draw straight lines, perpendiculars, oblique lines with any angle and equidistant cross section lines.
Description
The utility model relates to a kind of a kind of combined mapper that is suitable for industry drawing usefulness such as machinery, engineering, and it mainly is made up of T-square and bevel protractor etc.
At present, when industries such as machinery, engineering are drawn all kinds of figure, mostly adopt following two class drawing instruments: a class is instruments such as common T-square, set square, bevel protractor.Adopt above-mentioned instrument to draw, when drafting had the oblique line of certain angle, essential plotting speed was slow through angulation, setting-out two procedures, and error is also big.Another kind of is similar 851 popular draught machines, and when drawing with this appliances, for draw not too convenient that long straight line just shows on drawing, also not too convenient when drawing the oblique line that spacing equates, the structure of this appliances is more complicated also, and price is higher.
The purpose of this utility model provides a kind of simple in structure, with low cost with regard to being to overcome above-mentioned weak point of the prior art, not only can draw various straight lines easily, and can draw a kind of combined mapper of the oblique line with certain angle fast.
The purpose of this utility model can realize by following measure:
Promptly T-square and bevel protractor are coupled together, be being connected of T-square and locator by the incompatible realization that matches of the groove that processes on the guide rail that is provided with on the T-shaped related scale and the locator with locator; Bevel protractor is connected by screw with locator; Be processed with a through hole at the middle part of locator, in this through hole screw be housed; Bevel protractor is provided with the arc-shaped slot concentric with the bevel protractor cylindrical.
Locator on the combined mapper of the present utility model is provided with the angle pointer, or angle indication groove is set.The centre point of middle part through hole equates apart from the distance of bevel protractor centre point on the radius R of the arc-shaped slot that is provided with on the bevel protractor and the locator.The cross section of T-shaped related scale upper rail be shaped as swallow-tail form; Groove on the locator is a dovetail groove.
The drawing of accompanying drawing is described as follows:
Fig. 1: front view.
Fig. 2: cutaway view.
Do with detailed description below in conjunction with accompanying drawing (embodiment):
As shown in the figure, the utility model mainly is made up of T-square (1), locator (2) and bevel protractor (4), and T-square (1) and being connected of locator (2) are by the dovetail groove that processes on guide rail on the T-shaped related scale (its cross section be shaped as swallow-tail form) and the locator (2) realization that matches.The circle centre position of bevel protractor (4) has a counterbore, and the top of coupled locator (2) is processed with a through hole, by screw (5) bevel protractor (4) and locator (2) is linked together.Also be provided with an arc-shaped slot concentric on the bevel protractor (4) with the cylindrical of bevel protractor, there is a through hole at the middle part of locator (2), this through hole equals the radius R of arc-shaped slot apart from the centre-to-centre spacing of bevel protractor (4) centre point, screw (7) is positioned at the through hole at arc-shaped slot and locator (2) middle part, can make bevel protractor (4) rotate or be positioned on a certain angle around screw (5) by adjusting lock nut (6).
Also be provided with angle pointer (3) on the locator (2) so that when picture has the oblique line of certain angle correct calibration.
When using combined mapper of the present utility model T-square and chart board are close to, utilize T-square can draw straight line and vertical line, cooperating of guide rail on the groove of bevel protractor by locator and the T-shaped related scale, can make bevel protractor move left and right above or below T-square.When picture has the line of certain angle, only need the rotational angle chi, required angle value is aimed at pointer, tighten locking nut then bevel protractor and locator are locked, optional position on the drawing that can draw, straight line at any angle.Also can utilize the scale value of T-square that pointer is aimed at the draw equidistant hatching and the parallel lines of various spacings.
That combination plotter of the present utility model not only has is easy to use, the horizontal line of the longer dimension that can draw easily, and at any angle oblique line and equidistant hatching, also has simple in structure, cheap advantage.
Claims (4)
