Abstract
The utility model relates to a stationary and in particular relates to a multifunctional ruler. The multifunctional ruler is provided with an annular outer ring, a fixed cross beam and a rotation ruler, wherein the fixed cross beam is arranged on the central line of the inner side of the annular outer ring; two symmetrical semicircular frames are formed between the fixed cross beam and the annular outer ring; a hole is formed in the center of the fixed cross beam; the rotation ruler is arranged on the inner side of the annular outer ring; the central hole of the rotation ruler is connected with that of the fixed cross beam through a center shaft; and angle scribed lines are formed on the annular outer ring. By utilizing a drawing tool, namely the multifunctional ruler, a variety of patterns such as straight lines, circles, circular arcs, circular rings, measured angles and any angle can be drawn. The multifunctional ruler can be used for saving time, increasing the learning efficiency, and bringing convenience to work and study.
Description
Technical field
The utility model relates to stationery, is specially a kind of multi-functional ruler-compasses.
Background technology
People need use set square, compasses, protractor etc. usually when mapping, existing drawing tool majority all is to be separated from each other, to be used alternatingly, and are very inconvenient, in the time of especially need drawing various annulus arbitrarily, angle or radian, cumbersome.
The utility model content
The purpose of the utility model is to provide a kind of multi-functional ruler-compasses, solves in the prior art problems such as ruler function singleness.
The technical scheme of the utility model is:
A kind of multi-functional ruler-compasses; This ruler is provided with annular outer ring, fixed cross beam, rotation chi, and the inboard center line of annular outer ring is provided with fixed cross beam, forms two semicircle frames of symmetry between fixed cross beam and the annular outer ring; The fixed cross beam center drilling; The rotation chi is arranged at the annular outer ring inboard, and rotation chi centre bore, fixed cross beam centre bore connect through central shaft, on annular outer ring, have the angle groove.
Described multi-functional ruler-compasses, the angle groove is by 0 ° of-360 ° of distribution.
Described multi-functional ruler-compasses, the rotation chi be the structure that can rotate around central shaft, rotates chi and said semicircle frame, fixed cross beam and angle groove formation protractor.
Described multi-functional ruler-compasses transversely has the crossbeam groove that is used for setting-out at fixed cross beam.
Described multi-functional ruler-compasses transversely has the rotation chi groove that is used for setting-out at the rotation chi.
Described multi-functional ruler-compasses transversely has the ruler graduation mark at the rotation chi.
Described multi-functional ruler-compasses, ruler graduation mark are that two rows are symmetrical set.
The beneficial effect of the utility model is:
1, use the described drawing tool of the utility model, the various figures that can draw, as: draw straight line, draw circle, draw circular arc, annulus, angulation and do arbitrarily angled etc.
2, the utility model can be saved time, and improves learning efficiency, and brings convenience to working and learning.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1 annular outer ring; 2 angle grooves; 3 fixed cross beams; 4 crossbeam grooves; 5 rotation chis; 6 rotation chi grooves; 7 central shafts; 8 ruler graduation marks.
The specific embodiment
As shown in Figure 1, the utility model multi-functional ruler-compasses mainly comprises: annular outer ring 1, angle groove 2, fixed cross beam 3, crossbeam groove 4, rotation chi 5, rotation chi groove 6, central shaft 7, ruler graduation mark 8 etc., and concrete structure is following:
Annular outer ring 1 inboard center line is provided with fixed cross beam 3; Form two semicircle frames of symmetry between fixed cross beam 3 and the annular outer ring 1, on annular outer ring 1, have angle groove 2, angle groove 2 is by 0 ° of-360 ° of distribution; Fixed cross beam 3 center drillings; Rotation chi 5 is arranged at annular outer ring 1 inboard, and rotation chi 5 centre bores, fixed cross beam 3 centre bores connect through central shaft 7, can form protractor with said semicircle frame, fixed cross beam 3 and angle groove 2 around the rotation chi 5 of central shaft 7 rotations; In addition, transversely have the crossbeam groove 4 that is used for setting-out at fixed cross beam 3, transversely have the rotation chi groove 6 that is used for setting-out at rotation chi 5, transversely have ruler graduation mark 8 at rotation chi 5, ruler graduation mark 8 is that two rows are symmetrical set.
At annulus, when drawing circle or circular arc, can utilize annular outer ring 1 directly to accomplish, very convenient; If, annulus as required, angle or radian, plug-in mounting nib on rotation chi groove 6 under the rotation of rotation chi 5, cooperates the annulus that can accomplish all size, circle or circular arc at any angle with fixed cross beam 3.
