Abstract
The utility model relates to a take compasses of protractor. It includes an annular base, be equipped with the annular groove along its circumferencial direction level on the ring side wall in annular base, a plectane passes through to set up in the annular groove of annular flange activity joint in annular base on its lateral wall, along being carved with the angle scale interval along its circumferencial direction outside annular base upper surface, be carved with the length scale interval at the plectane upper surface along its direction of radius, evenly be equipped with the vertical through -hole that runs through the plectane of a plurality of in every length scale interval and the position that the plectane radius intersects, centre of a circle department is equipped with a location cap bottom the plectane. Its simple structure, reasonable in design, portable not only can not cause the damage of paper in the drawing, but also can be accurate draw out the circular arc of required angle and measure the number of degrees of circular arc, the commonality is strong, has solved the problem that exists among the prior art.
Description
Technical field:
The utility model relates to a kind of compasses with protractor.
Background technology:
Conventional compasses determine its center of circle of drawing with draw point usually, but these type of compasses easily cause the damage of paper in drawing.In addition, these type of compasses can only draw circle, cannot draw the circular arc of the accurate number of degrees and measure the number of degrees, and versatility is not strong, brings puzzlement to drawing.
Utility model content:
The utility model provides a kind of compasses with protractor, its structure is simple, reasonable in design, be easy to carry, the damage of paper not only can not be caused in drawing, but also the circular arc of required angle can be drawn out accurately and measure the number of degrees of circular arc, highly versatile, solve problems of the prior art.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of compasses with protractor, comprise an annular base, in annular base, ring-side wall is provided with annular groove along its circumferencial direction level, one plectane is connected in the annular groove in annular base by the annular flange flange active card be arranged on its sidewall, angle index value is carved with along its circumferencial direction at annular base upper surface outer edge, length scale value is carved with along its radial direction at plectane upper surface, evenly be provided with several through holes vertically running through plectane in the position that each length scale value is crossing with plectane radius, bottom plectane, circle centre position is provided with a positioning cap.
Annular base outer shroud sidewall is provided with a cavity, and be threaded in cavity port a seal cover, and a pen core horizontal card matched with hole size is located on the seal cover in cavity.
Several grooves are provided with along its even circumferential at plectane upper surface.
An annular slipmat is provided with along its even circumferential at annular base lower surface.
The utility model adopts such scheme, and structure is simple, reasonable in design, is easy to carry, not only can not causes the damage of paper in drawing, but also can draw out the circular arc of required angle accurately and measure the number of degrees of circular arc, highly versatile.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A portion cross-sectional schematic in Fig. 1.
Fig. 3 is B portion close-up schematic view in Fig. 1.
In figure, 1, annular base; 2, annular groove; 3, plectane; 4, annular flange flange; 5, through hole; 6, positioning cap; 7, cavity; 8, seal cover; 9, pen core; 10, groove; 11, annular slipmat.
Detailed description of the invention:
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
As Figure 1-3, a kind of compasses with protractor, comprise an annular base 1, in annular base 1, ring-side wall is provided with annular groove 2 along its circumferencial direction level, one plectane 3 is connected in the annular groove 2 in annular base 1 by annular flange flange 4 active card be arranged on its sidewall, angle index value is carved with along its circumferencial direction at annular base 1 upper surface outer edge, length scale value is carved with along its radial direction at plectane 3 upper surface, several through holes 5 vertically running through plectane 3 are evenly provided with in the position that each length scale value is crossing with plectane 3 radius, bottom plectane 3, circle centre position is provided with a positioning cap 6.
Annular base 1 outer shroud sidewall is provided with a cavity 7, and pen core 9 horizontal card that the seal cover 8, that is threaded in cavity 7 port matches with through hole 5 size is located on the seal cover 8 in cavity 7.Can person easy to use operate when there is no paintbrush.
Several grooves 10 are provided with along its even circumferential at plectane 3 upper surface.Person easy to use carrys out armature 3 by pressing groove 10.
An annular slipmat 11 is provided with along its even circumferential at annular base 1 lower surface.Better stationary annular base 1, improves the stability of drawing.
During use, hand-held annular base 1, the positioning cap 6 of plectane 3 lower surface is aimed at the circle centre position on drawing, then is outwards back-outed in the side of seal cover 8 from annular base 1, pen core 9 on seal cover 8 being aimed at needing on plectane 3 draws in the through hole 5 of relevant radii, the plectane 3 that press...withes one's finger rotates, plectane 3 slides along with in the annular groove 2 of the annular flange flange 4 being arranged on its edge in annular base 1, after completing, seal cover 8 is taken out, the damage of paper not only can not be caused in drawing, but also the circular arc of required angle can be drawn out accurately and measure the number of degrees of circular arc, highly versatile.
Above-mentioned detailed description of the invention can not as the restriction to the utility model protection domain, and for those skilled in the art, any alternate modification make the utility model embodiment or conversion all drop in protection domain of the present utility model.
The utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
