Description
Technical field
The present invention relates to the protractor that a kind of study and work is used, particularly relate to have protractor, the structure of the multiple use angle protractor of set square, ruler and trigonometric function computing function.
Background technology
Protractor, set square and ruler are the indispensable instruments that large, medium and small student and engineers and technicians draw, and existing these instruments generally all are single-pieces independently, and number of packages is many, wedge angle is many, carries, takes care of inconvenience, simultaneously, the cost height, instrument disperses, and uses inconvenient.Trigonometric function and Pythagorean theorem also are the knowledge that the student must learn, but the calculating of trigonometric function and Pythagorean theorem and memory are all cumbersome, generally will be by tabling look-up and complicated calculating could solve.If can have a kind of on the market at the less drawing tools of use, when realizing conventional the picture, neither need to table look-up, also do not need calculator, just can solve the computational problem of the trigonometric function of complexity and Pythagorean theorem easily by drawing tools, will improve working and learning efficient effectively.
Summary of the invention
Purpose of the present invention is exactly for satisfying the needs in market, provide a kind of simple in structure, manufactures easily, and cost is low, and function is many, easy to use, multiple use angle protractor flexibly.
The object of the present invention is achieved like this, multiple use angle protractor, it is characterized in that being provided with the fan-shaped main scale and the revolute pair chi in right angle of a hollow, transfer secondary chi, the pen cap, the chi card, the inside and outside side of two right angle side plates of main scale is respectively equipped with the long measure groove, the circular arc limit is provided with arc guide barrel, circular arc limit outer rim is provided with the angle groove, one end of the revolute pair chi place, right angle in main scale that is connected through the hinge, the other end of revolute pair chi is provided with pointer, the pointer end is provided with button pin, the middle part of revolute pair chi is provided with the linear guide groove of strip length unit's groove, the center line of linear guide groove and hinge, pointer is on same center line, transfer secondary chi and be provided with the long measure groove, an end of transferring secondary chi is connected with the pointer end pins of revolute pair chi by button pin with the pen cap, and the chi clip is stuck on the right angle side plate of main scale.
Described connection is transferred edge line that center and the secondary chi of transfer of the button pin of secondary chi be provided with the long measure groove in a straight line.
The width of described two right angle side plates equates.
The other end of the secondary chi of described transfer is set in the chi card on the right angle side plate.
The present invention is simple in structure, manufactures easily, and cost is low, and function is many, and is easy to use, flexible.Main scale can be done normal protractor, set square, ruler use.Transfer secondary chi can be along with the rotation of revolute pair chi up and down and move left and right.The chi card can use as required, and when needing, the other end of transferring secondary chi is set in the chi card on the right angle side plate, can control the secondary chi of transfer and remain plumbness.Button pin has lock function, when the revolute pair chi turns to a certain particular location, push the lock platform that button pin makes button pin and be inserted in the arc guide barrel locking, its pointer has just been pointed out the size (position shown in Figure 1 is 40 °) of its angle, in its linear guide groove, get final product the straight line of picture by the corresponding angle in the center of circle, and the scale of transferring on the secondary chi has just shown its sine value, the reading of position is 64.3mm as shown in Figure 1, sin40 °=0.643 (=64.3/100) so, the reading of corresponding main scale inside edge is 76.5mm, i.e. cos40 °=0.765 (=76.5/100).Along the guide groove of revolute pair chi slid underneath left, when the reading 5 (cm) of its limit and main scale inside edge when overlapping, its reading is 42mm with the secondary chi of transfer, and its tangent value tg40 °=0.84 (=42/50) in like manner can conveniently obtain its cotangent value so.
The pen cap and button pin are fixed together, and distance of center circle is 20mm, the pen cap is overlapped the back insert paintbrush with line channel, and the movable button pin is also locking to the position that needs, and can hinge be the center of circle promptly, and corresponding radius is drawn circle.
Because the right-angle side form right angle triangle of secondary chi of the transfer of revolute pair chi, mark card and main scale is so can solve the problem that any Pythagorean theorem quadratic sum is opened root.
If the chi card on the secondary chi of cancellation transfer, the secondary chi of transfer can be rotated arbitrarily and move, transfer secondary chi and revolute pair chi and main scale and can constitute triangle at any angle again, can solve and to calculate the length of side and the angle problem that could solve by complicated trigonometric function with the cosine law.
Revolute pair chi and the secondary chi of transfer cooperate, and can also make the parallel lines of any direction.
This multiple use angle protractor also can be used as compasses and uses when using as common protractor, set square and ruler, more can solve the relevant issues of trigonometric function and Pythagorean theorem, has realized the function and the purpose of one-object-many-purposes.
