Abstract
Be accurate to compasses of 0.1mm, the circular arc that draws or radius of a circle can be allowed to be accurate to 0.1mm, can be met some and want radius of circle to be accurate to the special requirement of 0.1mm.The compasses of 0.1mm can be accurate to, main scale to be fixed on compasses supporting leg and vertical with supporting leg, compasses nib to be fixed on vernier scale and vertical with main scale, and vernier scale is enclosed within main scale and can slides on main scale, and also can be fixed is bolted on main scale, main scale scale unit is 1mm, vernier scale scale unit is 0.9mm, and compasses nib is provided with ink port, and ink port has ink seam to lead to nib, the line of the zero graduation line on nib and vernier scale is perpendicular to vernier scale, and nib and nib are made up of stainless steel.Utilize the principle of slide measure that the distance of supporting leg and nib is transferred to the radius of a circle length that radius will be accurate to 0.1mm, pinch compasses squeezing handle on paper, just easily can draw circle.
Description
Technical field
The utility model relates to a kind of compasses being accurate to 0.1mm, and the circular arc drawn or radius of a circle especially can be allowed to be accurate to 0.1mm, can meet some and want radius of circle to be accurate to the special requirement of 0.1mm.
Background technology
The distance of current most of compasses supporting leg and nib measures according to drawing radius of a circle standard rule, can only be accurate to 1mm, can not meet some and want radius of circle to be accurate to the special requirement of 0.1mm.
Summary of the invention
In order to the distance overcoming current most compasses supporting leg and nib measures according to drawing radius of a circle standard rule, 1mm can only be accurate to, can not meet some wants radius of circle to be accurate to the deficiency of the special requirement of 0.1mm, the utility model provides a kind of compasses being accurate to 0.1mm, the circular arc that draws or radius of a circle can be allowed to be accurate to 0.1mm, can be met some and want radius of circle to be accurate to the special requirement of 0.1mm.
The utility model solves the technical scheme that its technical problem adopts: the compasses that can be accurate to 0.1mm, main scale to be fixed on compasses supporting leg and vertical with supporting leg, compasses nib to be fixed on vernier scale and vertical with main scale, vernier scale is enclosed within main scale and can slides on main scale, also can be fixed is bolted on main scale, main scale scale unit is 1mm, vernier scale scale unit is 0.9mm, compasses nib is provided with ink port, ink port has ink seam to lead to nib, the line of the zero graduation line on nib and vernier scale is perpendicular to vernier scale, and nib and nib are made up of stainless steel.The principle of liquid surface molecular tension is utilized to instill in ink port by ink, ink is sewn to along ink and reaches nib, the distance of supporting leg and nib is transferred to the radius of a circle length that radius will be accurate to 0.1mm by the principle of recycling slide measure, fix the position of vernier scale on main scale with set bolt again, pinch compasses squeezing handle on paper, just easily can draw circle; Nib and nib are made up of stainless steel, and the nib in such nib flexural deformation can not remain corresponding with the graduation position on main scale in the process of drawing.
The beneficial effects of the utility model are, the circular arc that draws or radius of a circle can be allowed to be accurate to 0.1mm, can meet some and want radius of circle to be accurate to the special requirement of 0.1mm.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is: the structure chart that can be accurate to the compasses of 0.1mm.
Fig. 2 is: the structure chart that can be accurate to the nib of 0.1mm.
In figure, 1. squeezing handle, 2. supporting leg, 3. nib, 4. main scale, 5. vernier scale, 6. main scale scale, 7. vernier scale scale, 8. set bolt, 9. ink seam, 10. ink port, 11. nibs.
Detailed description of the invention
In FIG, the compasses of 0.1mm can be accurate to, it is upper and vertical with supporting leg (2) that main scale (4) is fixed on compasses supporting leg (2), it is upper and vertical with main scale (4) that compasses nib (3) is fixed on vernier scale (5), vernier scale (5) is enclosed within can in the upper slip of main scale (4) on main scale (4), also the bolt (8) that can be fixed is fixed on main scale (4), main scale scale (6) unit is 1mm, vernier scale scale (7) unit is 0.9mm, compasses nib (3) is provided with ink port (10), ink port (10) has ink seam (9) to lead to nib (11), the line of the zero graduation line on nib (11) and vernier scale (5) is perpendicular to vernier scale (5), nib (11) is made up of stainless steel.The principle of liquid surface molecular tension is utilized to be instilled by ink in ink port (10), ink arrives nib (11) along ink seam (9), the distance of supporting leg (2) and nib (3) is transferred to the radius of a circle length that radius will be accurate to 0.1mm by the principle of recycling slide measure, use set bolt (8) to fix the position of vernier scale (5) on main scale (4) again, pinch compasses squeezing handle (1) on paper, just easily can draw circle.
?in Fig. 2, compasses nib (11) is provided with ink port (10), ink port (10) has ink seam (9) to lead to nib (11), the line of the zero graduation line on nib (11) and vernier scale (5) is perpendicular to vernier scale (5), nib (3) and nib (11) are made up of stainless steel, and the nib (11) like this in nib (3) flexural deformation can not remain corresponding with the graduation position on main scale (4) in the process of drawing.
