Abstract
The utility model relates to a trisection angular resolver which is characterized in that a main measuring needle and the middle point of a swing rod are connected by a shaft. A slide rod perpendicular to a rod body is arranged at one third of the swing rod. One end of the swing rod is installed on a slide way. One end of an assisting measuring needle is arranged on the slide way and the other end is installed on the shaft. The utility model has the advantages of simple structure, convenient use and accurate measuring.
Description
Technical field
The utility model relates to the schooling apparatus technical field, and particularly a kind of trisection of an angle is divided device.
Background technology
When separating for the trisection of an angle, method commonly used is to measure its whole angle with protractor, again divided by three, calculate the numerical value at each angle, and then mark out the trisection of an angle with protractor, with the ruler line, its shortcoming is all can produce error in each step of measuring, calculating and mark at last, its overlay error is just bigger, also exists in addition to use inconvenient shortcoming.
Summary of the invention
The purpose of this utility model provides a kind of easy to use and little trisection of an angle of error and divides device.
The utility model is to realize like this, the mid point that it is characterized in that main surveyingpin and fork is connected by axle, is provided with the slide bar perpendicular with shaft at 1/3rd places of fork, and an end of fork is arranged on the chute, one end of auxilliary surveyingpin is arranged on the chute, and the other end is installed on the axle.
The utlity model has simple in structure, easy to use and measure advantage accurately.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described;
Fig. 1 is the structural representation that the trisection of an angle is divided device;
Fig. 2 be Fig. 1 along A-A to profile.
The specific embodiment
Shown in Fig. 1-2, this trisection of an angle divides device to comprise main surveyingpin 1, fork 2, slide bar 3, auxilliary surveyingpin 4 and chute 5, the mid point of main surveyingpin 1 and fork 2 is connected by axle 6, be provided with the slide bar 3 perpendicular at 1/3rd places of fork 2 with shaft, one end of fork 2 is arranged on the chute 5, one end of auxilliary surveyingpin 4 is arranged on the chute 5, and the other end is installed on the axle 6, and step is during use; The center of circle that first trip divides the trisection of an angle device with overlapped by the summit of subangle, then main surveyingpin 1 and auxilliary surveyingpin 4 are overlapped with dividing the arm of angle respectively, fork 2 rotates to auxilliary surveyingpin 4 from main surveyingpin 1, when rotating to main surveyingpin 1, fork 2 with chute 5 intersection points, the angle between main surveyingpin 1 and the fork 2 is exactly by 1/3rd of subangle.
