Abstract
The utility model relates to the graduated compasses of a kind of band.It comprises support, this support contains the first supporting leg and the second supporting leg, and the first supporting leg and the second supporting leg are all hinged on support in shaft-like and their upper end, and jug on support, the lower end of the first supporting leg is connected with compasses head, and the lower end of the second supporting leg is connected with nib; It is characterized in that the lower end of the first supporting leg is connected with tape measure, the overhanging end of tape measure is hinged on the lower end of the second supporting leg.These compasses do not need the circle getting final product picture required size by other size tool, and operating process is comparatively simple, and the time of consumption is shorter, and when the distance when between supporting leg changes, user can learn at once.
Description
Technical field
The utility model relates to a kind of drawing tool, is specifically to determine the graduated compasses of the band of drawn radius of circle fast.
Background technology
Compasses draw round instrument as a kind of, are widely used in teaching, in the industries such as building.At present, the compasses used in industry comprise support, and comprise support, this support contains two supporting legs, on the upper end thereof support of two supporting legs, and jug on support, the lower end of a supporting leg is connected with compasses head, and the lower end of another supporting leg is connected with nib.During use, first open two supporting legs, then utilize a survey tool (as rule) to measure the distance of nib and compasses point to determine drawn radius of a circle, afterwards compasses point is inserted in paper, centered by this supporting leg, axle revolves and turns around, and nib draws circle on paper when rotated.Traditional compasses only have basic picture circle function, during use, the concrete size of drawn circle need be determined by other survey tools, operating process is more loaded down with trivial details, the time consumed is longer, and draw occur that supporting leg changes the distance between supporting leg because colliding other article in circle process time, user cannot learn at once, causes the circle that draws undesirable.In addition, once user does not have other size tool at one's side, the circle of required size cannot just be drawn.
Utility model content
The technical problems to be solved in the utility model is to provide the graduated compasses of a kind of band, these compasses do not need the circle getting final product picture required size by other size tool, and operating process is comparatively simple, and the time of consumption is shorter, when distance when between supporting leg changes, user can learn at once.
For solving the problem, provide following technical scheme:
The graduated compasses of band of the present utility model comprise support, this support contains the first supporting leg and the second supporting leg, first supporting leg and the second supporting leg are all hinged on support in shaft-like and their upper end, and jug on support, the lower end of the first supporting leg is connected with compasses head, and the lower end of the second supporting leg is connected with nib.Be characterized in that the lower end of the first supporting leg is connected with tape measure, the overhanging end of tape measure is hinged on the lower end of the second supporting leg.
Wherein, described tape measure is steel tape.
Take above scheme, have the following advantages
Because the lower end of the first supporting leg of the graduated compasses of band of the present utility model is connected with tape measure, the overhanging end of tape measure is hinged on the lower end of the second supporting leg.During use, open two supporting legs, the size be drawn out by scale in tape measure can directly know drawn radius of a circle, do not need the distance coming amount nib and compasses point again with other size tool, make picture circle process become simple, thus shorten the time of picture circle, and when occurring that supporting leg changes supporting leg spacing situation because colliding other article in picture circle process, user learns at once by the change of tape measure pull-out size, and the circle that draws can not be made undesirable.In addition, the circle of required size also can be drawn when user does not have other size tool at one's side.
Accompanying drawing explanation
Fig. 1 is the structural representation of the graduated compasses of band of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As described in Figure 1, the graduated compasses of band of the present utility model, comprise stainless steel stent 1, this support 1 is containing the first supporting leg 2 and the second supporting leg 21, first supporting leg 2 and the second supporting leg 21 are all in shaft-like and their upper end is all hinged on support 1, and the lower end of jug 3, first supporting leg 2 is connected with compasses head 4 on support 1, the lower end of the second supporting leg 21 is connected with nib 5.It is characterized in that the lower end of the first supporting leg 2 is connected with tape measure 6, the overhanging end of tape measure 6 is hinged on the lower end of the second supporting leg 21.
During use, first open the first supporting leg 2 and the second supporting leg 21, the size that then scale is drawn out from steel tape 6 determines radius of a circle to be painted, is finally inserted in paper by compasses point, centered by the first supporting leg 2, axle revolves and turns around, and namely nib 5 draws the circle of needs when rotated on paper.
Claims (2)
1. be with graduated compasses, comprise support (1), this support contains the first supporting leg (2) and the second supporting leg (21), first supporting leg (2) and the second supporting leg (21) are all in shaft-like and their upper end is all hinged on support (1), and the upper jug (3) of support (1), the lower end of the first supporting leg (2) is connected with compasses head (4), and the lower end of the second supporting leg (21) is connected with nib (5); It is characterized in that the lower end of the first supporting leg (2) is connected with tape measure (6), the overhanging end of tape measure (6) is hinged on the lower end of the second supporting leg (21).
2. the graduated compasses of band as claimed in claim 1, is characterized in that described tape measure (6) is steel tape.
