Principle of work of the present utility model: the utility model is made up of main scale 1, slip chi 2, rotary ruler 3, slide block 4, pair chi 5, spring leaf 6, angle scale 7, a pair angle scale 8, and a pair chi 5 is fixed on the slide block 4, slide block 4 is positioned at the inside chute of each chi, have vernier graduation on each pair chi 5, each has scale above the chi, angle scale 7 usefulness axle connects with slip chi 2, slip chi 2 is below main scale 1, axle is in the sliding tray of main scale 1, secondary angle scale connects with slide block 4 in main scale 1 sliding tray, and joins with angle scale 7.Another angle scale 7 is fixed on the back side, an end of main scale 1, and another secondary angle scale 8 is connected in rotary ruler 3 back sides that are positioned at below main 1, and the coupling spindle of rotary ruler 3 is positioned at the hole, the back side of main scale 1, and the slide block 4 usefulness axle in slip chi 2, rotary ruler 3 sliding trays connects.One side has spring leaf 6 between the internal chute of each slide block 4 and each chi, can control and guarantee its degree of accuracy.When definite φ length dimension on one side on main scale 1, and get an angle, slip slip chi 2, rotary ruler 3 all can form a triangle, can obtain the correct number at other two limit, two angles.

The utility model compared with prior art, because this combination ruler has three axles to connect three chis, and there are combinations such as the chi of paying, slide block, angle scale, pair chi, pair angle scale, spring leaf to guarantee that this combination ruler is simple in structure, saving of work and time during use, the degree of accuracy height, limit size, angle that can be as requested only need one to draw a rotation, can obtain required size and angle, it is simple to operate, is suitable for just, high school student and industry, scientific research, national defence operating personnel's use.

Embodiment of the present utility model:

The triangulation calculation combination ruler is made up of main scale 1, slip chi 2, rotary ruler 3, slide block 4, pair chi 5, spring leaf 6, angle scale 7, a pair angle scale 8, as shown in Figure 1.Wherein above-mentioned each part removes spring leaf and all can adopt plastics, nylon, organic glass, aluminium alloy, steel plate to process, and spring leaf 6 can be made with spring steel plate.Wherein main, sliding, rotary ruler 1,2,3 its shapes as shown in Figure 1, the chi body has slide slot in the centre, slide block 4 usefulness can be installed, and standard scale is arranged, paying on the chi 5 has vernier graduation, angle scale 7, pays on the angle scale 8 angle is arranged.One end shape of main scale 1 is shown in Fig. 3,4,5.

To pay chi 5 is fixed on the slide block 4, and place respectively in the slide slot in the main scale 1, slide rule 2, rotary ruler 3, angle scale 7 is positioned at above the main scale 1 and connects with the slip chi 2 of axle with main scale below, connects on the slide block 4 of one pair of angle scale 8 and main scale 1, joins with angle scale 7 on it.Another angle scale 8 connects with the back side, main scale one end, and rotary ruler 3 is positioned at main scale 1 groove herein, and the coupling spindle of its end inserts in the hole, the back side of main scale 1, and another pair angle scale 8 connects with the back side of rotary ruler 3, and joins with herein angle scale 7.Slip chi 2 be positioned at rotary ruler 3 above, and slide block 4 one ends in two chis connect with axle, one end of slide block is associated with the screw that can fix, on one side spring leaf 6 places the slide block 4 and the slide slot of main scale 1, slip chi 2, rotary ruler 3 to locate respectively, forms the triangulation calculation combination ruler.
