Description
The utility model relates to a kind of chi, rule instrument, belongs to the stationery field.
Existing drawing instrument is more, all has certain function, but does not see and the identical report of the utility model.
The purpose of this utility model is to provide a kind of use and easy to carry, the chi that gathers multi-function in integral whole, rule instrument.
The utility model is achieved in that this chi, rule instrument are linked according to a conventional method by ruler 2, the ruler 3 that is made as one and protractor 4 and form, and vernier scale 1 is loaded on the ruler 2.The upper sideline of ruler 3 is a wave, and the left side is provided with the boss 6 that matches with vernier scale 1.Have several small sircle holes on the symmetrical center line of protractor 4.The front of vernier scale 1 has hole 7, and the bottom surface has the groove 9 that cooperates with ruler 2, and the side has the groove 8 that cooperates with boss 6.The section geometric of ruler 2 is identical with groove 9 section geometric.The back side of chi, rule instrument was always a plane after assembling finished.
Accompanying drawing 1 is chi, rule instrument installation diagram.
Accompanying drawing 2 is the front view of ruler 3 and protractor 4.
Accompanying drawing 3 is the front view of ruler 2.
Accompanying drawing 4 is the shaft side figure of vernier 1.
The utility model is described in further detail below in conjunction with accompanying drawing: this chi, rule instrument are linked according to a conventional method by ruler 2, the ruler 3 that is made as one and protractor 4 and form, and vernier scale 1 is loaded on the ruler 2.The upper sideline of ruler 3 is a wave, and the left side is provided with the boss 6 that matches with vernier scale 1.Have 10 small sircle holes on the symmetrical center line of protractor 4.The front of vernier scale 1 has hole 7, and the bottom surface has the groove 9 that cooperates with ruler 2, and the side has the groove 8 that cooperates with boss 6.The section geometric of ruler 2 is identical with groove 9 section geometric.The back side of chi, rule instrument was always a plane after assembling finished.This chi, rule instrument have following purposes respectively:
When 1, drawing longer straight line and wave, remove the screw of vernier scale 1 earlier, ruler 2 Rotate 180 degree can be constituted the long ruler of a length, can finish the drafting of straight line and wave this moment.
When 2, drawing vertical line,, can obtain vertical line with the ruler connection after taking away instrument earlier with stamping a little in the small sircle hole of pen on these instrument protractor 4 symmetrical center line.
3, draw less than or greater than the circle and the circular arc of protractor 4 sizes.Picture is during less than the circle of protractor 4 or circular arc, inserts the hinge joint hole with screw earlier and as the center of circle, inserts in the small sircle hole of protractor 4 with pencil as required, and rotation can obtain required figure.Picture is during greater than the circle of protractor 4 or circular arc, earlier with screw insertion hinge joint hole and as the center of circle, along ruler 2 moving cursor chis 1, also digital quarter by the top sight gauge in hole 7, in the hole with pencil insertion hole 7 bottoms, rotation can obtain required figure simultaneously as required.
The left end and the locking that vernier scale 1 are moved to ruler 2 and 3 are return, still can be used for drawing beeline, semicircle, measuring angle etc. behind the return.
The utility model compared with prior art, have simple in structure, easy to carry, multiple functional, cost is low The advantage such as honest and clean is widely used in each level personnel, and can be used as teaching aid.
