Abstract
The utility model provides a multifunctional graph drawing ruler, wherein a moveable supporting foot is fixedly connected with a fixed supporting foot and a bevel gauge through a rotation shaft, the upper end of the moveable supporting foot is provided with a compass cap, the moveable supporting foot and the lower end of the fixed supporting foot are both provided with socketed legs, a chute is arranged on the fixed supporting foot, a mobile bevel gauge and a rotation ruler are fixed on the chute of the fixed supporting foot through a slide screw, a chute is arranged on the rotation ruler, and a slip ruler is fixed on the chute of a mobile ruler through a fastening screw. The multifunctional graph drawing ruler not only has the functions of drawing appliances such as a compass, a bevel gauge, a ruler and the like, but also can accurately draw out triangular graph through using the multifunctional graph drawing ruler separately,. The utility model has the advantages of convenient employment, flexibility, reasonable design, simple structure and the like, which can bring great convenience for teachers to draw, and a great amount of drawing time is saved, and therefore, the multifunctional graph drawing ruler has excellent popularization and utilization values.
Description
1, technical field
The utility model relates to a kind of schooling apparatus, specifically a kind of multi-functional picture chi of the usefulness that is used to impart knowledge to students and draw.
2, background technology
The drawing instrument that present teacher student often uses mainly contains: set square, compasses, protractor, ruler, its function, structure are all single especially, when going to school and leaving school at every turn, teacher all to carry a large amount of drawing instruments, special inconvenient, instrument in the replacing hand that when drawing, also needs not stop, waste the quality time of giving a lesson for this reason, influenced the normal progress of teaching.
Be a teacher on blackboard and draw in the triangular graph, some situation can accurately not drawn out, and allows classmates can accurately not observe relation between each figure, the angle, solves a problem, understands for classmates and all brought certain inconvenience.
3, summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of and can accurately draw out the leg-of-mutton multi-functional picture chi that has compasses, protractor, ruler function simultaneously.
The technical solution of the utility model realizes in the following manner, its movable leg and fixed feet, protractor are connected and fixed by rotating shaft, the upper end of movable leg is provided with the compasses cap, the lower end of movable leg and fixed feet all is provided with the rule pin, fixed feet is provided with chute, bevel protractor and rotary ruler are fixed on the chute of fixed feet by sliding screw, and rotary ruler is provided with chute, and the slip chi is fixed on the chute of adjustable rule by trip bolt.
The utility model has the advantages that: this device has not only possessed the functional characteristics of drawing instruments such as compasses, protractor, ruler, can also draw out triangle accurately simultaneously.Also needn't carry a large amount of drawing instruments when teacher goes to class has again gone, only just can independently finish drawing work with this device, also needn't worry, and this device is very easy to use, carries more convenient in the teaching process of can not lose time for the replacing instrument.
4, description of drawings
Accompanying drawing 1 is the structural representation of multi-functional picture chi;
Accompanying drawing 2 is the structural representation after multi-functional picture chi shrinks;
Mark in the accompanying drawing is represented respectively; 1, protractor; 2, movable leg, 3, the slip chi; 4, trip bolt; 5, chute; 6, bevel protractor; 7, sliding screw; 8, fixed feet; 9, rule pin; 10, rotating shaft; 11, compasses cap; 12, rotary ruler.
5, the specific embodiment
Below in conjunction with accompanying drawing 1-2 multi-functional picture chi of the present utility model is done following detailed description the in detail.
As shown in drawings, multi-functional picture chi of the present utility model its movable leg 2 and fixed feet 8, protractor 1 is connected and fixed by rotating shaft 10, fixed feet 8 is arranged in the middle of protractor 1 and the movable leg 2, movable leg 2 can rotate freely, the upper end of movable leg 2 is provided with compasses cap 11, movable leg 2 all is provided with rule pin 9 with the lower end of fixed feet 8, rule pin 9 is provided with the pen cap of replaceable chalk, fixed feet 8 is provided with chute 5, bevel protractor 6 is fixed on the chute 5 of fixed feet 8 with rotary ruler 12 by sliding screw 7, slip chi 3 and bevel protractor 6 are movable on can the chute 5 in fixed feet 8 when regulating sliding screw 7, rotary ruler 12 is provided with chute 5, slip chi 3 is fixed on the chute 5 of rotary ruler 12 by trip bolt 4, when regulating trip bolt 4, can make slip chi 3 stretch out increase length, fixed feet 8, movable leg 2, rotary ruler 12, all marked scale on the slip chi 3.
Movable leg 2 and fixed feet 8 can be separated when needing the picture circle, the radius of selecting to be fit to can be finished; Can regulate sliding screw 7 under as the situation of knowing three edge lengths when needs are drawn triangle exactly makes fixed feet 8 select suitable length, rotate rotary ruler 12 then and be adjusted to suitable length, the triangle in movable leg 2, fixed feet 8, rotary ruler 12 besieged cities is exactly the accurate figure that will draw, goes out to get final product with stroke; Under the situation of knowing an Atria angle size, at first rotary moveable leg 2 is made suitable angle according to protractor 1, makes rotary ruler 12 and fixed feet 8 also be rotated into the angle of precognition then, goes out to get final product with stroke then.
Multi-functional its processing and fabricating of picture chi of the present utility model is very simple and convenient, can process shown in the accompanying drawing to specifications.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
