Abstract
The utility model provides a novel drawing compass who can be used to civil engineering drawing which on one on compasses foot was fixed in the angle calibrated scale, the another was provided with the size groove on angle calibrated scale and the size scale frame in arranging the slip track in, and the refill can be laid in slip compasses underfooting, and angle calibrated scale and size scale were put up center support antifriction bearing and were linked to each other, and sliding foot upper portion is equipped with the locking spiral can fix the sliding foot position, is equipped with angle and size pointer on the compasses foot, the convenient location. The utility model discloses size and the angle that has had the figure can also be measured simultaneously with the radius to the steerable circular arc corner of painting, and service function is comprehensive.
Description
Technical field
This utility model relates to Civil Engineering Drawing technical field, it is provided that a kind of accurate Drawing can determine radius and determine the compasses of angle circular arc.
Background technology
At present, widely used compasses of drawing are compasses, and a compass foot is equipped with positioning needle, and another compass foot is provided with compasses pen.Determine home position by bow compass positioning pin during drafting, promote another compass foot to rotate around positioning needle.Determine radius owing to existing compasses can only carry out accurate Drawing by protractor and ruler and determine circular arc or the circle of angle, causing drawing course to waste time and energy.It addition, existing compasses cannot measure the radius of existing circle and the corner of the upper any point-to-point transmission of circle, use function singleness.
Summary of the invention
This utility model purpose is in that providing a kind of draws the drawing compass determining corner and radius, and this compasses simple in construction is easy and simple to handle, when drawing the circular arc determining corner and radius without using protractor and ruler to measure, uses complete function.
This utility model solves its technical problem and be the technical scheme is that a kind of drawing compasses that can be used for Civil Engineering Drawing, including the setting circle regulation foot fixed and the slidably compass foot being enclosed within compasses calibrating jig.Compasses calibrating jig is provided with size scale line on face, and fixing compass foot and slidably compass foot are provided with tuning drive gear.Being provided with compass foot sliding rail in compasses calibrating jig, fixing compass foot is connected by rolling bearing with lower section angle dial, and rolling bearing is arranged in compasses centre mount and ensures that compasses rotate smooth-going.Slidably compass foot top is furnished with stop spiral, bottom fixed installation picture pen core.Slip compass foot high scale pointer is specified on the scale and is drawn circle or arc radius.Drawn circular arc-shaped corner specified by fixing compass foot tuning drive gear on angle index.
The beneficial effect that this use is novel: this utility model band is angled and length scale, it is not necessary to can draw by other drawing instruments or measure the circular arc or circle of determining corner and radius, its design science is reasonable, and simple in construction is flexible and convenient to use.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure schematic diagram.
Fig. 2 is this utility model slip compass foot structural representation.
Fig. 3 is this utility model angle dial structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.Overall structure schematic diagram as it is shown in figure 1, include angle dial 5, angle indicator 4, center of circle fixing point 3, size scale frame 2, length pointers 6 and stop spiral 1.In described size scale frame, 2 are provided with sliding rail.Slidably compass foot structural representation is as in figure 2 it is shown, comprise slide block 7, stop spiral 1 and pen core placing device 8.Described slide block 7 is positioned in sliding rail, and slide block 7 size and sliding rail width match, it is ensured that pointed is perpendicular to graduation mark direction accurately to point out required scale；Described slide block about 7 is fixed by stop spiral 1, slide block 7 can be made to be fixed on sliding rail by screwing stop spiral 1；Described pen core placing device 8 bottom can place the pen core specifying specification according to actual needs.Angle dial structural representation is as it is shown on figure 3, described center of circle fixing point 3 is used for determining the center of circle fixing ruler；Described angle dial adopts rolling bearing 9 to be connected with superstructure, and superstructure can relatively rotate with angle dial.
This utility model practical approach is: the center of circle in being drawn with center of circle fixing point 3 alignment, makes angle indicator point to 0 °, regulates slip foot to suitable dimension, tightens the fixing slip foot of stop spiral, rotates compasses calibrating jig and draw.
Claims (1)
1. the drawing compasses that can be used for Civil Engineering Drawing, it is characterized in that: bottom angle graduated disc connects compasses center support by rolling bearing, center support can with bottom angle graduated disc coaxial rotation, and this axle by drafting circle the center of circle, fixing compass foot size pointed angle dial, slip compass foot sliding rail end face is provided with size scale line, slip compass foot top is provided with bottom stop spiral and is provided with pen core placing device can fixedly mount pencil-lead, and slip compass foot can be slided in the sliding rail of calibrating jig and be fixed by stop spiral.
