Abstract
The utility model discloses a pair of compasses with scales. The compasses with the scales comprise a slide rod, a fixing part and a slide part, wherein the fixing part and the slide rod are fixedly connected; the slide part and the slide rod are glidingly connected; the cross section of the slide rod is rectangular; and the scales are arranged on the slide rod. Therefore, the compasses with the scales have the advantages that the structure is simple, a circle with precise radius can be drawn without external measuring tools, and the compasses are convenient to use.
Description
Technical field
The utility model relates to a kind of compasses, more precisely is a kind of compasses with the scale note.
Background technology
Compasses of the prior art must be confirmed radius of a circle with instrument in addition at the picture bowlder; Use inconvenient; And the circle that this mode determines the radius inaccuracy, and compasses of the prior art regulate the radius of a circle of being drawn out through the angle of regulating two stitch, center of circle pin and lead for retractable pencil can not be simultaneously perpendicular to drawing the plane; The thickness of the circle of being drawn out is inhomogeneous, and error is bigger.
The utility model content
The utility model mainly is to solve the existing in prior technology technical problem, thereby provides a kind of simple in structure, and it is round accurately not need externally measured instrument promptly can draw out radius, the compasses of band scale note easy to use.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of compasses with the scale note; Comprise a slide bar, a fixed part and a sliding part, described fixed part is fixedly connected with described slide bar, and described sliding part and described slide bar are slidingly connected; The cross section of described slide bar is a rectangle, and described slide bar is provided with scale.
As the utility model preferred embodiment; Described fixed part comprises a fixed block, one first tightening knob, a center of circle pin connecting cylinder and a center of circle pin; Described fixed block is provided with a connecting hole, and the size of described connecting hole and the size of described slide bar adapt, and described first tightening knob is connected with the top of described fixed block; Described center of circle pin connecting cylinder is connected with the bottom of described fixed block, and described center of circle pin is connected with described center of circle pin connecting cylinder.
As the utility model preferred embodiment; Described sliding part comprises a movable block, one second tightening knob, a lead for retractable pencil connecting cylinder and a lead for retractable pencil; Described movable block is provided with a sliding eye; The size of described sliding eye and the size of described slide bar adapt, and described second tightening knob is connected with the top of described movable block, and described lead for retractable pencil is connected with described lead for retractable pencil connecting cylinder.
As the utility model preferred embodiment; Described sliding part also comprises a Z-shaped plate, an adjusting depression bar and a stage clip; Described Z-shaped plate and described movable block are rotationally connected; Described lead for retractable pencil connecting cylinder is connected with the bottom of described Z-shaped plate, and described adjusting depression bar and described Z-shaped plate and described movable block are slidingly connected, and the two ends of described stage clip are connected with described Z-shaped plate and described movable block.
Therefore the advantage of the compasses of the band scale of the utility model note is, and is simple in structure, and it is round, easy to use accurately not need externally measured instrument promptly can draw out radius.
