Description
Technical field:
The present invention relates to a kind of cultural goods, particularly a kind of chi tool that will have now is modified into a kind of multiduty composite ruler tool.
Background technology:
Original chi tool all has the cm scale, and the effect of this series products is to draw simple wire to constitute thing, is applicable to the students of the junior years, but for higher grade pupil and other people member, can't realize than accurate Drawing.Some producer tackles key problems to this, and Tong Hang major part is the simple geometry figure in the market, as circle, ellipse, square etc., makes basic Geometric figure drawing simple.But have many problems in actual use: one is to use scope single.The user only can use the chi tool in high-frequency aspect line drawing, the simple geometry, and almost utterly useless in other respects; The 2nd, precision is low.The existing chi tool in market is 10 calibration (1/10cm), drafting relate to 3 calibration (1/3cm), 4 calibration (1/4cm), 6 calibration (1/6cm) equal indicative and
Cm,
Irrational number length aspect errors such as cm then strengthen suddenly, have a strong impact on the accuracy rate of drawing performance; The 3rd, the inconvenience of operation.The guide groove mouth of graphing can't satisfy all kinds of requirements with pen, brings very big trouble even difficulty to the user, has prolonged the time of drawing virtually.
Summary of the invention
The object of the present invention is to provide a kind of above-mentioned shortcoming of overcoming, have that the scope of application is wide, error is little, simple to operation, can on same instrument, carry out the drafting of multiple image, strengthen the convenience of reasonability, reliability and the operation of chi tool, improve a kind of compound chi tool of study and work efficient.
For achieving the above object, the technical solution adopted in the present invention is: this composite ruler tool comprises that a side of chi tool is provided with the top for domatic of cm scale and cm scale, it is characterized in that: on the chi tool, be provided with several card-coating lattice guide holes, hyperbola figure guide groove, SIN function figure guide groove, parabola figure guide groove, logarithm/power function figure guide groove, tan figure guide groove, protractor guide groove, inverse proportion functional digraph guide groove, compound function figure guide groove, elliptical aperture, circular port.
Described a kind of composite ruler tool is characterized in that: the front longitudinal middle part of chi tool is made as concave surface, and above-mentioned several guide holes, guide groove and pore size distribution are on concave surface.
Described a kind of composite ruler tool is characterized in that: the cross section of hyperbola figure guide groove, SIN function figure guide groove, parabola figure guide groove, logarithm/power function figure guide groove, tan figure guide groove is the loudspeaker tubular, big narrow base suitable for reading.
Described a kind of composite ruler tool is characterized in that: the vertical side of chi tool is provided with the cm scale, and chi tool vertically another side is provided with the irrational number scale.
Described a kind of composite ruler tool is characterized in that: in the set cm scale of the vertical side of chi tool, have every cm is divided into 10 calibration, also have with every cm be divided into 6 calibration, 7 calibration, 8 calibration, 9 calibration one of them.
Described a kind of composite ruler tool is characterized in that: the upper surface of chi tool is a shiny surface, and lower surface is a frosting.
The present invention's beneficial effect compared with prior art:
The higher multiple mathematics set of images of frequency of utilization had made things convenient for the user to draw than standard graphics together widely during this chi will impart knowledge to students, learn, works.This chi scope of application is wide, error is little, simple to operation, can on same instrument, carry out the drafting of multiple image, strengthened the convenience of reasonability, reliability and the operation of chi tool further, improved user's study and work efficient.

The specific embodiment:
Describe one embodiment of the present of invention in detail below in conjunction with accompanying drawing:
As Fig. 1, Fig. 2, shown in Figure 4, chi tool length overall is 208mm, and wide is 31mm, and the upper surface of chi tool is a shiny surface, and lower surface is a frosting.The vertical side of chi tool is provided with cm scale 13, and 0-160mm is that every cm carves 10 calibration in the cm scale 13, and 16-17cm, 17-18cm, 18-19cm, 19-20cm are respectively every cm and carve 6,7,8,9 calibration, are provided with chamfering domatic 15 on cm scale 13; Chi tool vertically another side is provided with the doubly unreasonable length of list commonly used
Irrational number scale 14.Be provided with the long concave surface 12 of 20mm that is for 188mm is wide at the front of chi tool longitudinal middle part, card-coating lattice guide hole 1, hyperbola figure guide groove 2, SIN function figure guide groove 3, parabola figure guide groove 4, logarithm/power function figure guide groove 5, tan figure guide groove 6, protractor guide groove 7, inverse proportion functional digraph guide groove 8, compound function figure guide groove 9, elliptical aperture 10, circular port 11 is distributed on the concave surface 12.
As shown in Figure 3, the cross section of hyperbola figure guide groove 2, SIN function figure guide groove 3, parabola figure guide groove 4, logarithm/power function figure guide groove 5, tan figure guide groove 6 is the loudspeaker tubular, big narrow base suitable for reading makes it can be suitable for the use of all kinds of pens.
For convenient the use at circular port 11 marks the part particular values as 0, π/4, pi/2,3 π/4, π, 5 π/4,3 pi/2s, 7 π/4,2 π.
Only there is certain phase difference in cosine function, so this image also can be expressed as y=cosx x ∈ [π, 0] (also being the monotonic increase interval) because just.Just, the cosine function image can be finished drafting by this chi tool.
Tangent y=tanx x ∈ [0, π/4] is similar to the design concept of y=sinx, and y=tanx also can carry out translation, variations such as symmetry and upset, just, the cotangent functional picture all can finish drafting by this chi tool.
Card-coating lattice 1 stay enough spaces at market card-smearing writing appliance pen core size design, and the card-coating accuracy rate can reach 100%, make card-coating easier, more convenient, faster.
