Abstract
A combined graduated compasses is composed of a triangular graduated scale, a fixed axle and a slide axle, the triangular graduated scale is installed to the fixed axle, the slide axle is installed to the triangular graduated scale for directly reading out the needed size to make a circle, the triangular graduated scale can be detached for independent use, and a cutter blade is installed to the triangular graduated scale for cutting paper and pencil.
Description
The utility model relates to a kind of drawing instrument, particularly a kind of combination scale compasses.
At present the widely used compasses of people at the bowlder of drawing certain radius, must be measured required size from rule earlier and remake circle, and this kind compasses only have picture and justify function, and purposes is single.
The purpose of this utility model provides a kind of combination scale compasses, is marked with scale at these compasses, draws the certain size bowlder and can therefrom directly read data.
The purpose of this utility model is achieved in that a kind of combination scale compasses, form by fixed axis, trigonometric scale, movable axis, be provided with perpendicular shape recessed joint on fixed axis top, a right-angle side of trigonometric scale is provided with groove and by groove trigonometric scale is fixed on the fixed axis; Another of trigonometric scale right-angle side is provided with horizontal groove, and movable axis upper end is provided with recessed joint and is installed in the groove on another right-angle side of trigonometric scale by recessed joint.
On the trigonometric scale hypotenuse, blade is housed.
The utility model combines set square and compasses, and circle that can the disposable required radius that draws has been expanded the function of compasses; Trigonometric scale is removable to be used separately down; Blade is housed on the trigonometric scale can be used for cutting a sheet of paper, cut work such as pen.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model fixed axle structure schematic diagram.
Fig. 3 is the utility model movable axis structural representation.
Fig. 4 is the utility model trigonometric scale structural representation.
During use, the groove 2 of 8 one right-angle sides of trigonometric scale is inserted in the recessed joint 4 of fixed axis 5 and fix, the recessed joint 6 of movable axis 7 is inserted in the groove 3 of another right-angle side of trigonometric scales 8, make the movable axis 7 can be, draw circle after reading scale along groove 3 smooth sliding of trigonometric scale 8.If draw a radius and be 2 centimetres circle, then sliding axle 7 is moved and cause 2 centimeters of marking on the trigonometric scale 8, serve as that the axle rotation is promptly drawn to such an extent that a radius is 2 centimetres a circle with fixed axis 5.Sliding axle 7 is unloaded from trigonometric scale 8, trigonometric scale 8 is unloaded for 5 times from fixed axis can use trigonometric scale 8 separately, and can utilize the blade 1 on the set square to cut a sheet of paper, cut pen.
Claims (2)
1, a kind of combination scale compasses are made up of fixed axis, trigonometric scale, movable axis, it is characterized in that fixed axis top is provided with perpendicular shape recessed joint, and a right-angle side of trigonometric scale is provided with groove and by groove trigonometric scale is fixed on the fixed axis; Another of trigonometric scale right-angle side is provided with horizontal groove, and movable axis upper end is provided with recessed joint and is installed in the groove on another right-angle side of trigonometric scale by recessed joint.
2, combination scale compasses according to claim 1 is characterized in that on the trigonometric scale hypotenuse blade being housed.
