Abstract
The utility model provides a convenient multi -purpose angular bisector chi of mapping, belongs to the manual instrument field of mapping. Its scheme includes protractor, rhombus chi and diagonal chi, has solved the complicated difficulty of angular bisector mapping step. Through fixing at the rhombus chi of protractor and the diagonal chi of taking the slide rail, angular bisector is realized once only drawing in the angle of equalling divide equally that need not to calculate the angle. Have convenient and fast, easy operation, simple manufacture, the multi -purpose advantage of a chi. Be applicable to student study, mr gives lessons and manual mapping task such as designer in.
Description
Technical field
The utility model relates to a kind of geometric construction instrument, and particularly a kind of convenient multiplex angular bisector drawing ruler, belongs to manual plotting field of tool.
Background technology
For student, teacher and some be the staff designed, need some manual figure of picture, many times need, an angle bisection, to need to make angular bisector.Following 4 steps to be carried out when generally drawing angular bisector.The first step is the angle drawing needs with protractor; Second step, the half-angle calculating this angle is how many; 3rd step measures half-angle, and on point, point makes a mark; 4th step, connects angle point and angular bisector gauge point.Make angular bisector generally like this, need several steps, pretty troublesome, waste time and energy, inconvenient quick.
Summary of the invention
The utility model aims to provide a kind of convenient and swift, handy angular bisector drawing ruler.
Scheme of the present utility model comprises protractor, rhombus chi and diagonal chi, it is characterized in that: rhombus chi and diagonal chi one end are fixed on the circle centre position of protractor, and diagonal chi is buckled through the slip on rhombus chi.
Described rhombus chi is formed by connecting by four isometric high-quality transparent plastic ruler head and the tail, and connecting material is that metal is rotationally connected button, and four rulers of rhombus chi can be movable in junction, but formed shape is rhombus always.
Described diagonal tape has slide rail, and has scale, adopts high-quality transparent plastic, and one end is by being rotationally connected the circle centre position buckled and be fixed on protractor together with rhombus chi, and the other end is buckled through the slip on rhombus chi, can be slided by slide rail in slip button.
Described rhombus chi and diagonal chi can close up, and can use under closed configuration as ruler.
Its good effect is
1., because rhombus chi and diagonal chi are in the setting of protractor, disposablely can complete the work of picture angle peace subangle, be convenient to angular bisector mapping.
2. because rhombus chi and diagonal chi can close up, and diagonal chi there is scale, straight length accurately can be drawn, achieve a chi multiplex.
So the utility model has in the mapping task being applicable to student, teacher and designer etc., draw angular bisector convenient and swift, and it is multiplex to realize a chi, makes simple, advantage easy to use.
Accompanying drawing explanation
Accompanying drawing is example structure schematic diagram, and figure comprises: protractor (1), centre point (2), rhombus chi (3), diagonal chi (4), slip buckle (5), junction button (6).
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Embodiment as shown in the figure, is made up of protractor (1), rhombus chi (3) and diagonal chi (4).Connected by junction button at centre point (2) place of protractor (1) and stretch out two isometric rulers, with another two isometric rulers, by junction button (6) composition rhombus chi (3), the diagonal chi (4) of a band slide rail is filled at centre point (2) place, with slip button (5), diagonal chi (4) and rhombus chi (3) are linked, to adjust the size of angle, the diagonal chi (4) of rhombus chi (3) and band slide rail has scale, ruler can be worked as use under closed configuration, draw the straight line of precise length.When needing the angular bisector drawing an angle, angle throughput hornwork (1) between two points of rulers being fixed on the rhombus chi (3) of protractor centre point (2) is determined, now only need to pin angular bisector drawing ruler, do not allow it movable, diagonal chi (4) is because remain it is the diagonal of rhombus chi (3), so diagonal chi (4) is just in diagonal positions after angle is determined, then draw angle and angular bisector along two points of rulers of rhombus chi (3) and diagonal chi (4).
The utility model preferably resolves the difficulty of angular bisector patterning step complexity, is applicable to Students ' Learning, teacher gives lessons and in the Hand drawing task such as designer, convenient and swift, improves drawing efficiency, and has the multiplex advantage of a chi.
Claims (4)
1. a convenient multiplex angular bisector drawing ruler, comprises protractor, rhombus chi and diagonal chi, it is characterized in that: rhombus chi and diagonal chi one end are fixed on the circle centre position of protractor, and diagonal chi is buckled through the slip on rhombus chi.
2. the convenient multiplex angular bisector drawing ruler of the one according to claims 1, it is characterized in that: rhombus chi is formed by connecting by four isometric high-quality transparent plastic ruler head and the tail, connecting material is that metal is rotationally connected button, four rulers of rhombus ruler can rotate in connection buckle, but formed shape is rhombus always.
