Description

A kind of practical angle drawing device

Technical field

The utility model relates generally to drawing instrument field, more particularly to a kind of practical angle drawing device.

Technical background

Angle needs to be carried out with protractor substep current one, the picture on paper at any angle, the long period is taken, using not It is convenient.

Utility model content

The utility model purpose is exactly that angle needs to be carried out with protractor substep at any angle in order to solve one, picture, is taken A kind of problem of long period, there is provided practical angle drawing device.

The utility model is achieved through the following technical solutions：

A kind of practical angle drawing device, it is characterised in that：Rotary scale, main body rack, rotating shaft cap are included, rotary scale includes Dynamic scale, upper rotating shaft, lower rotary shaft, semicircular ring are raised, and dynamic scale is thin cuboid, and upper rotating shaft is fixed in lower end upper surface, upper to turn Axle is a quarter cylinder, moves the fixed lower rotary shaft in scale lower end top, and lower rotary shaft is semicylinder, in lower rotary shaft semicylinder Outer is raised semicircular ring.

The main body rack includes quiet scale, angle scale, and angle scale is thin semi-circular ring, and quiet scale is generally length Cube, is empty a quarter cylinder in the upper half storey of cuboid, is empty semicylinder in the lower half storey of quiet scale cuboid, And there is semi-circular shape groove the outer along the empty semicylinder in the upper half storey lower surface of quiet scale cuboid upwards, cuts out quiet Scale left half lower half slice width degree and empty semicylinder radius identical part, rotary scale are arranged on the quiet scale of main body rack On, both form gap cooperation, and there is semi-circular shape groove the upper surface of quiet scale cuboid.

The rotating shaft cap is 3/4ths thin cylinders, and outer edge is downwardly convex to form 3/4ths protruding rings, and it half Footpath is identical with the radius of quiet scale cuboid upper surface semi-circular shape groove, and rotating shaft cap is fixedly mounted on the upper rotating shaft of rotary scale On, a quarter breach longitudinal edge of rotating shaft cap and rotary scale the right along concordant, the downward annular protrusion of rotating shaft cap with it is quiet Scale cuboid surface annular groove is inlayed, and both form gap cooperation.

Described a kind of practical angle drawing device, it is characterised in that：The thickness of the lower rotary shaft semicylinder and dynamic scale thickness Identical, shaft radius are slightly larger in lower rotary shaft semicylinder radius ratio, and their axial line overlaps, as the rotary shaft of rotary scale Heart line.

Described a kind of practical angle drawing device, it is characterised in that：The axial line of the empty semicylinder, empty a quarter The axial line of cylinder, the axial line three of rotary scale overlap.

Described a kind of practical angle drawing device, it is characterised in that：The dynamic scale and quiet scale indicate length scale, angle mark Chi indicates angle index.

Principle of the present utility model is：

When drawing more than 0 degree less than or equal to an angle of 90 degrees, the right of dynamic scale to be drawn along alignment the angle index at angle, along moving Scale and quiet scale directly draw two sides at angle, and can compare the length scale on dynamic scale and quiet scale, put on two The length on bar side.When needing picture to be less than the angle of 180 degree more than 90 degree, dynamic scale is first in the position less than an angle of 90 degrees On, a line at angle is first drawn along quiet scale, then dynamic scale is drawn angle in needing on the scale at angle of picture along dynamic scale Other a line.

The utility model has the advantages that：

Disposably two sides at angle can be drawn using the utility model, and can directly mark two length on side, and With angle measuring function, the utility model is easy to use, simple structure, low cost of manufacture, there is extraordinary market promotion prospect.

Brief description of the drawings

Accompanying drawing 1 is floor map of the present utility model.

Accompanying drawing 2 is a kind of structural representation of the rotary scale of practical angle drawing device.

Accompanying drawing 3 is a kind of structural representation of the rotating shaft cap of practical angle drawing device.

Accompanying drawing 4 is a kind of structural representation of the main body rack of practical angle drawing device.

Specific embodiment

As shown in figure 1, a kind of practical angle drawing device, includes rotary scale, main body rack, rotating shaft cap 1, rotary scale includes Dynamic scale 2, upper rotating shaft 3, lower rotary shaft 4, semicircular ring projection 5, it is thin cuboid to move scale 2, and upper rotating shaft is fixed in lower end upper surface 3, upper rotating shaft 3 is a quarter cylinder, moves the fixed lower rotary shaft 4 in the lower end of scale 2 top, and lower rotary shaft 4 is semicylinder, at lower turn The semicylinder outer of axle 4 is semicircular ring projection 5.

Main body rack includes quiet scale 6, angle scale 7, and angle scale 7 is thin semi-circular ring, and quiet scale 6 is generally grown Cube, is empty a quarter cylinder in the upper half storey of cuboid, is empty semicolumn in the lower half storey of the cuboid of quiet scale 6 Body, and there is semi-circular shape groove outer along the empty semicylinder in the upper half storey lower surface of the cuboid of quiet scale 6 upwards, digs The semicylinder radius identical part of the cuboid left half lower half slice width degree of quiet scale 6 and sky is gone to, rotary scale is arranged on master On the quiet scale 6 of body support frame, both form gap cooperation, and there is semi-circular shape groove the upper surface of the cuboid of quiet scale 6.
