Abstract
The utility model discloses an angle resolver which can divide angles of arbitrary sizes and which belongs to the mathematics field. The main structure comprises equal division bars and radial slide bars. The equal division bars are connected through fixing points. The radial slide bars are connected with the equal division bars through slide devices. The radial slide bars are connected with each other through joints. The distances between the joints to the slide devices are equal. Through the equilateral triangle theory, the utility model can equally divide angles with arbitrary sizes without a compass or a ruler.
Description
Technical field
The utility model relates to a kind of mathematical tool, particularly a kind ofly the angle can be carried out any five equilibrium Arbitray angle divider.
Background technology
What the five equilibrium at diagonal angle adopted usually is that compasses and ruler carry out, and process is comparatively complicated, operation inconvenience.
Summary of the invention
The purpose of this utility model is will provide a kind of can carry out any five equilibrium in the diagonal angle, Arbitray angle divider simple to operation without compasses and ruler.
The purpose of this utility model is achieved in that a kind of Arbitray angle divider, comprise five equilibrium bar 1 and slide bar 3 radially, five equilibrium bar 1 connects by fixing point 2, radially slide bar 3 links to each other with five equilibrium bar 1 by slider 4, radially connect by joint 5 between the slide bar 3, it is isometric that joint 5 is arrived between the slider 4.
The utility model since adopt be the five equilibrium bar and radially slide bar combine and structure, utilize the principle of equilateral triangle that five equilibrium is carried out at any angle, simple to operate, easy to use.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Structure of the present utility model as shown in Figure 1, a kind of Arbitray angle divider comprises five equilibrium bar 1 and slide bar 3 radially, five equilibrium bar 1 connects by fixing point 2, radially slide bar 3 links to each other with five equilibrium bar 1 by slider 4, radially connects by joint 5 between the slide bar 3, and it is isometric that joint 5 is arrived between the slider 4.
The utility model method of operating is as follows, with the trisection of an angle is example, fixing point 2 with halver overlaps with the summit at angle earlier, slide bar 3 makes the five equilibrium bar on both sides overlap with the both sides at angle by slider 4 by spurring radially, put on a little on the five equilibrium bar place straight line in the angle again, to put with fixing point 2 again and be connected, can be with the angle trisection.
Can be when the utility model is made according to maximum umbers of desiring sub-multiple angle and branch bar 1 such as decision and radially slide bar 3 how much.The effect that radially connects between the slide bar 3 is played in joint 5.
