From above cable trunking, cut the operation instruction of embodiment of gage (A)～(E), when the length on the limit that will measure when this benchmark ruler unit 4 is less than the length on the limit that multiplying power ruler unit 51,52 will measure, the unit scales of multiplying power ruler unit 51,52 can be respectively relatively the unit scales of this benchmark ruler unit 4 dwindle a specific trigonometric function numerical value multiplying power corresponding with acute angle.And the length on the limit that will measure when this benchmark ruler unit 4 is while being greater than the length on the limit that multiplying power ruler unit 51,52 will measure, the unit scales of multiplying power ruler unit 51,52 can be distinguished the unit scales of this benchmark ruler unit 4 relatively and amplify a specific trigonometric function numerical value multiplying power corresponding with acute angle.By this design, make cable trunking cut gage (A)～(E) when measuring a certain edges thereof length of right-angle triangle 900,901, can directly by multiplying power ruler unit 51,52, read other two edge lengths, quite convenient and practical.

As shown in Figure 7, the utility model cable trunking cut the second preferred embodiment of gage and this first preferred embodiment difference be in: the unit scales of multiplying power ruler unit 51,52 with respect to this benchmark ruler unit 4 dwindle enlargement ratio design, and also different for measuring the mode of three edge lengths of right-angle triangle.For convenience of description, below will only for the present embodiment and this first preferred embodiment difference place, be described.

In the present embodiment, this cable trunking cuts and on gage (F), is provided with a benchmark ruler unit 4, and two multiplying power ruler unit 51,52, and multiplying power ruler unit 51,52 has different convergent-divergent multiplying powers with respect to this benchmark ruler unit 4 respectively.The unit scales of this multiplying power ruler unit 51 is the unit scales of this benchmark ruler unit 4 doubly, the unit scales of this multiplying power ruler unit 52 is 2 times of unit scales of this benchmark ruler unit 4.This benchmark ruler unit 4 that this cable trunking cuts gage is the opposite side a that are designed for measuring 30 ° of angles of right-angle triangle, and can coordinate multiplying power ruler unit 51,52 to draw respectively the length of adjacent side b and hypotenuse c.

Coordinating and to consult Fig. 8,9, next, is that the bending that is applied to an enclosed type cable trunking 8 with the present embodiment cuts measurement, illustrates that this cable trunking cuts the length of side how gage (F) to be applied to the right-angle triangle at 30 ° of angles and measures.When cutting the partial section of the cable trunking 8 of the front and back extension shown in Fig. 8, lay equal stress on shown in composition diagram 9 there is the bending section 81 of 30 ° of angles of a left and right horizontal deviation and 10cm time, need cut two isosceles triangles 800 in this cable trunking 8, just can make to remain position and reassemble into required left and right horizontal deviation shape, the left and right width of this cable trunking 8 is 30cm.

With regard to the right-angle triangle 900 forming with regard to these the 30 ° of angles shown in Fig. 9, this opposite side a is 10cm, while obtaining this adjacent side b and hypotenuse c length, by this cable trunking, to be cut the multiplying power ruler unit 51 of gage (F), in 52, find out respectively the scale position of " 10 ", in this benchmark ruler unit 4, read respectively again the scale numerical value " 17.3 " corresponding with " 10 " scale position and " 20 ", just can this adjacent side b length be 17.3cm, and this hypotenuse c length is 20cm, and then the spacing that can know two isosceles triangles that will dismiss 800 is 20cm, namely these bending section 81 length d are 20cm.

Because the height of each isosceles triangle 800 is the width h(30cm that equal this cable trunking 8), and equal two adjacent side b ' length with the right-angle triangle 902 at 15 ° of angles of described isosceles triangle 800, due to so extrapolate the opposite side a ' length of the right-angle triangle at each 15 ° of angle, be so can be directly as shown in Figure 10 cable trunking cut the multiplying power ruler unit 51 of gage (F), in 52, find out respectively " 30 " scale position, in this benchmark ruler unit 4, find out respectively again the scale numerical value " 52 " corresponding with " 30 " scale position and " 60 ", scale numerical value " 60 " and " 52 " are subtracted each other, just can obtain this opposite side a ' length is 8cm, so can learn that the base e length of isosceles triangle 800 is 16cm, and then can learn the size of the isosceles triangle 800 that will cut, utilize Pythagorean theorem or the trigonometric function that needn't take a lot of trouble calculate one by one again, quite convenient and practical.

As shown in Figure 11,12,13, in like manner, when this benchmark ruler unit 4 that another cable trunking shown in the present embodiment Figure 11 cuts gage (G) be designed for measuring 60 ° of angles to edge lengths time, for measuring the convergent-divergent multiplying power of multiplying power ruler unit 51,52 of adjacent side and hypotenuse, need correspondence to be respectively adjusted into this benchmark ruler unit 4 doubly with doubly.

Therefore, when the partial section of the cable trunking 8 of the front and back extension shown in Figure 12 being cut, lay equal stress on form shown in Figure 13 there is the situation of a bending section 81 that bends up and down 60 ° of angles and 10cm time, the height h of this cable trunking 8 is 10cm, can be first cable trunking as shown in Figure 11 cut the hypotenuse c length that gage (G) draws 60 ° of angles of Figure 13 right-angle triangle 900 and be about 11.5cm, so two 60 ° of angle isosceles triangles, 800 spacing d that Figure 12 will cut are 11.5cm.And 60 ° of angle equal edge b ' length because of two right-angle triangles 902 in each 60 ° of angle isosceles triangle 800 of Figure 12, the height h(10cm that equals this cable trunking 8), so the scale position of correspondence " 10 " is found out in the multiplying power ruler unit 51 that can be directly cuts gage (G) by cable trunking, in this benchmark ruler unit 4, find out respectively again the scale numerical value corresponding with this " 10 " scale position and be about " 11.5 ", 30 ° of angle equal edge a ' length that just can obtain this right-angle triangle 902 are 11.5cm, so can learn that the base e length of isosceles triangle 800 is about 22cm, and then learn at once the size of the isosceles triangle 800 that will cut, suitable fast and easy.

During enforcement, also can on this carrier 3, set up another one multiplying power ruler unit (not shown), and the unit scales of this multiplying power ruler unit is this benchmark ruler unit 4 doubly, when recording the opposite side of 45° angle of an isosceles right triangle or adjacent side length with this benchmark ruler unit 4, can be by amplifying in this multiplying power ruler unit doubly, find out the scale position that is same as this adjacent side length, by this scale position mark, referred to the corresponding scale of this benchmark ruler unit 4 again, just can in this benchmark ruler unit 4, draw a scale numerical value, this scale numerical value is just the hypotenuse length of waist right-angle triangle.

That is to say, when the length on the limit that will measure when this benchmark ruler unit 4 is less than the length on the other both sides that multiplying power ruler unit 51,52 will measure, the unit scales of multiplying power ruler unit 51,52 can be distinguished this benchmark ruler unit 4 relatively and amplify a specific trigonometric function numerical value multiplying power corresponding with acute angle.Contrary, when the length on the limit that will measure when this benchmark ruler unit 4 is greater than the length on the other both sides that multiplying power ruler unit 51,52 will measure, the unit scales of multiplying power ruler unit 51,52 can be respectively relatively this benchmark ruler unit 4 dwindle a specific trigonometric function numerical value multiplying power corresponding with acute angle.

Therefore, when this benchmark ruler unit 4 that the present embodiment cable trunking cuts gage is while being designed for measuring the adjacent side length of a right-angle triangle, can according to the specific trigonometric function numerical value correspondence of acute angle, adjust multiplying power ruler unit 51 respectively, 52 unit scales convergent-divergent multiplying power, and can record after the length of this adjacent side in this benchmark ruler unit 4 equally, further coordinate multiplying power ruler unit 51, 52 draw the length on other both sides, and can cut three edge lengths that gage is measured a right-angle triangle fast by single cable trunking, and can convenient construction personnel directly carry out the linear measure longimetry of cable trunking and cut.

As shown in figure 14, the utility model cable trunking cuts the 3rd preferred embodiment of gage and this first preferred embodiment difference and is in the multiplier indicia 510,520 that multiplying power ruler unit 51,52 is set.Because the marking mode of the multiplier indicia 510,520 of two multiplying power ruler unit 51,52 is identical, for convenience of describing, below only with regard to the multiplier indicia 510 of this multiplying power ruler unit 51, describe.

In the present embodiment, that ruler graduated structure that cable trunking with the first embodiment cuts gage (A) is designed to benchmark and modifies, this multiplier indicia 510 of this multiplying power ruler unit 51 is except having the convergent-divergent multiplying power 511 with respect to the ruler scale of this benchmark ruler unit 4, an angle symbol 512 and a corresponding sides symbol 513 also with the position of the right-angle triangle certain edges thereof that is respectively used to represent that this benchmark ruler unit 4 is applicable, and the corresponding trigonometric function symbol 514 adopting of this convergent-divergent multiplying power 511.This angle symbol 512 is an angle value, and such as 30 °, 45 ° or 60 ° etc., this corresponding sides symbol 513 is divided into three kinds, be respectively represent hypotenuse "/", represent "-" of adjacent side, and represent " | " of opposite side.514 of this trigonometric function symbols are the wherein a kind of of " sin ", " cos ", " tan ", " csc ", " sec " and " cot ".And this multiplying power ruler unit 51 can arrange a plurality of multiplier indicia 510 in these carrier 3 length ranges, for example at least every 100 centimeters arrange a multiplier indicia 510.

That is to say, when this multiplier indicia of this multiplying power ruler unit 51 indicates, 510 be " cm: 30 °/sec " time, " cm: " be that the scale of this multiplying power ruler unit 51 is with respect to the convergent-divergent multiplying power of the scale of this benchmark ruler unit 4; " 30 °/sec " represent that the applicable right-angle triangle certain edges thereof in this benchmark ruler unit 4 is the hypotenuse at 30 ° of angles, and the corresponding trigonometric function adopting of this convergent-divergent multiplying power 511.
