Abstract
The utility model discloses a pair of multifunctional diameter compasses. The pair of multifunctional diameter compasses comprises a fixed leg (2), a movable leg (5) and a mark straight scale (4). The movable leg (5) is movably installed on the mark straight scale (4) through a lantern ring (6). A positioning screw (7) is arranged on the lantern ring (6). A rotating device (1) is arranged on the fixed leg (2). The rotating device (1) is fixedly connected with one end of the mark straight scale (4). A disc (3) is arranged at the upper portion of the fixed leg (2). The center, in the vertical direction, of the rotating device (1) is aligned with the datum line of the mark straight scale (4). Mark values are arranged on the disc (3). The movable leg (5) is perpendicularly installed on the mark straight scale (4). The pair of multifunctional diameter compasses has the advantages that angles of circular arcs can be measured, and circular arcs with known angles can be drawn.
Description
Technical field
The utility model relates to a kind of drawing instrument, especially relates to a kind of multi-functional diameter compasses.
Background technology
Often will use compasses in drawing course, come picture circle and radian very convenient with compasses, compasses commonly used have bipod to intersect and feet on parallel lines now, can both well draw round and circular arc, and the compasses of feet on parallel lines can also be measured the radius of round and circular arc.But in the process that will draw circular arc, the circular arc of the known angle of drawing or will measure the angle of circular arc the time, existing compasses just can not draw or can not measure.
The utility model content
The purpose of this utility model is the deficiency at existing product, and a kind of multi-functional diameter compasses that can take measurement of an angle is provided.
Multi-functional diameter compasses of the present utility model, comprise fixing feet, movable pin and scale ruler, described movable pin is movably arranged on the scale ruler by the collar, the described collar is provided with set screw, described fixing feet is provided with whirligig, described whirligig is fixedlyed connected with scale ruler one end, is provided with disk above the described fixing feet.Align with scale ruler datum line in the center of described whirligig vertical direction, described disk is provided with scale value, and described movable pin is vertically mounted on the scale ruler.
The utility model beneficial effect is: (1) because fixing feet is provided with the disk of scale value, can draw easily or the angle of measured place circular arc; (2) the scale ruler is provided with movable pin, can conveniently draw or measure the radius of circular arc.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: whirligig 1, fixing feet 2, disk 3, scale ruler 4, movable pin 5, the collar 6, set screw 7.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Multi-functional diameter compasses of the present utility model comprises whirligig 1, fixing feet 2, disk 3, scale ruler 4, movable pin 5, the collar 6 and set screw 7.
Described movable pin 5 is movably arranged on the scale value chi 4 by the collar 6, and the described collar 6 is provided with set screw 7, and described fixing feet 2 is provided with whirligig 1, and described whirligig 1 is fixedlyed connected with scale ruler 4 one ends, is provided with disk 3 above the described fixing feet 2.Align with scale ruler 4 datum lines in the center of described whirligig 1 vertical direction, described disk 3 is provided with scale value, and described movable pin 5 is vertically mounted on the scale ruler 4.
Before measuring arc angle, scale ruler 4 rotated to zero graduation on the disk 3 aligns, again movable pin 5 move on to the circular arc starting point that will take measurement of an angle on, rotate whirligig 1, movable pin 5 being forwarded on the circular arc terminal point, read the scale on the disk 3, is exactly the angle of the circular arc of surveying; When drawing the circular arc of known angle, rotate whirligig 1 and get final product to known angle.
Claims (4)
1. multi-functional diameter compasses, comprise fixing feet (2), movable pin (5) and scale ruler (4), it is characterized in that, described movable pin (5) is movably arranged on the scale ruler (4) by the collar (6), the described collar (6) is provided with set screw (7), described fixing feet (2) is provided with whirligig (1), and described whirligig (1) is fixedlyed connected with scale ruler (4) one ends, and described fixing feet (2) top is provided with disk (3).
