Abstract
A golden section ratio search device aims to solve the problem that a conventional drawing or calculation method for determining the golden section ratio of an object is complicated in operation and generates large errors due to repeated measurement. The golden section ratio search device includes a measuring tape, a main extension scale and a positioning tape; the main extension scale comprises a main ruler extension rod; and the measuring tape and the positioning tape are respectively fixed at one end of the main extension scale and at an end part of the main ruler extension rod which is outside the other end of the main extension scale. The golden section ratio search device is used to determine the golden section ration of the object, and then can be applied in the field of painting, sculpture, architecture, engineering design, and the like.
Description
Technical field
The utility model relates to a kind of finding device of point, is specifically related to a kind of for looking for the device of object golden section point.
Background technology
Golden section ratio is that the famous mathematician Bi Dagesi of ancient Greek found before more than 2500 years.Then in building, art and scientific experiment, be widely used.People, normally by using the drawing tools such as ruler, compasses, adopt the golden section point of an object of method searching of mapping in the past; Or measure the overall length of object, then through calculating the golden section point of searching object.Such method is troublesome poeration not only, and repeatedly measures the easily larger error of generation.
Summary of the invention
The purpose of this utility model is: a kind of finding device of golden section point is provided, to solve, determines at present the method that the golden section point of object generally adopts mapping or calculates, and complex operation not only, and repeatedly measure the problem that easily produces larger error.
Scheme of the present utility model is as follows: a kind of finding device of golden section point, comprise and measure tape measure, main shrinkage-rule and positioning tapeline, described main shrinkage-rule comprises main scale expansion link, measures tape measure and positioning tapeline and is separately fixed at one end of main shrinkage-rule and stretches the end at the main scale expansion link in main shrinkage-rule other end outside.
Main shrinkage-rule also comprises main scale main body, is provided with along its length draw-in groove in main scale main body, and draw-in groove connects one end of main scale main body, and main scale main body and main scale expansion link arrange in the same way, and one end of main scale expansion link is slidably arranged in draw-in groove.
Described measurement tape measure and positioning tapeline are all replaceable is tape.
The utility model compared with prior art, major advantage is to adopt shrinkage-rule to combine with tape measure or tape, utilize golden ratio to put definite ultimate principle, only need simple several step just can determine on object the golden ratio point along a direction, simple to operate, and only need one-shot measurement, avoided repeatedly measuring and produced the problem of larger error.

Embodiment
With reference to Fig. 6, golden section refers to analogy relation certain between things each several part, being about to integral body is divided into two, major part equals ratio whole and major part with the ratio that smaller part divides, its ratio is about 1: 0.618 or 1.618: 1, long section is 0.618 of full section, is below for construction with ruler and compasses, to find line segment AB golden section point to have done simple introduction:
First, cross the vertical line that B point is made AB, on vertical line, get a D and make BD equal half of AB;
Then, connect AD, the D point of take is the center of circle, and BD is that radius is justified, and hands over AD in an E;
Finally, the A point of take is the center of circle, and AE is that radius is justified, and hands over AB in a C, and C point is the golden section point of AB.
The method that tradition is found golden section point is to measure and numerical evaluation, in the time of complex operation, also easily produce larger error, the utility model is found golden section point according to the principle of geometry construction with ruler and compasses, with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, designed a kind of finding device of golden section point, comprise and measure tape measure 1, main shrinkage-rule 2 and positioning tapeline 3, described main shrinkage-rule 2 comprises main scale expansion link 22, measuring tape measure 1 and positioning tapeline 3 is separately fixed at one end of main shrinkage-rule 2 and stretches the end at the main scale expansion link 22 in main shrinkage-rule 2 other end outsides.Main shrinkage-rule 2 also comprises main scale main body 21, in main scale main body 21, be provided with along its length draw-in groove 23, draw-in groove 23 connects one end of main scale main body 21, and main scale main body 21 arranges in the same way with main scale expansion link 22, and one end of main scale expansion link 22 is slidably arranged in draw-in groove 23.Described measurement tape measure 1 and positioning tapeline 3 are all replaceable is tape.
Method of operating:
Step 1: measure the length of the object 4 that need to determine golden section point with measurement tape measure 1, the record length of surveying;
Step 2: the one end that the measuring junction (free end of tape measure) of measuring tape measure 1 is positioned to object being measured 4 length directions, make to measure the chi length direction of tape measure 1 and the length direction of object being measured 4 is perpendicular, meanwhile, the chi length of measuring tape measure 1 is adjusted to 1/2 of object being measured 4 length;
Step 3: adjust main shrinkage-rule 2, one end that main scale expansion link 22 is arranged on to main scale main body 21 outsides is positioned at the other end of object being measured 4 length directions;
Step 4: keep the position of main shrinkage-rule 2 and measure the chi of tape measure 1 long constant, make to measure tape measure 1 and stretch along the length direction of main shrinkage-rule 2;
Step 5: open positioning tapeline 3, the measuring junction of positioning tapeline 3 is positioned to the measuring junction place of measuring tape measure 1, guarantee that positioning tapeline 3 stretches;
Step 6: the chi length and the positioning tapeline 3 stiff end present positions that guarantee positioning tapeline 3 are constant, length direction by positioning tapeline 3 along object being measured 4 stretches, and is the golden section point of object being measured 4 in object being measured 4 with the corresponding point of free end of positioning tapeline 3.
