Abstract

The utility model relates to a multifunctional ruler. A quadrilateral plastic plate is perpendicular in the diagonals. Two slits are arranged along the diagonals and graduated according to the scale of the rectangular coordinate. The quadrilateral plastic plate is separated into four triangles through two slits. While in use, the ruler is used to measure the angles and lengths normally, draw the common right-angled triangles, isosceles right-angled triangles, quadrilaterals through the ruler structure and draw the axles of the rectangular coordinate with the perpendicular diagonals. The utility model has the advantages of simple structure, convenient use, high efficiency, quickness and precise measurement.

Description

Multifunctional ruler

Technical field the utility model relates to a kind of drawing survey tool, especially a kind of drawing rule with multiple function.

Technical background is well-known, and ruler is length, the angular surveying instrument of normal use in the study.Though but present ruler is various informative, function is different, every kind of ruler only possesses the function of measuring a few special angle, can't satisfy more demands of people.For this reason, we provide the more complete ruler of a kind of function very necessary.

The summary of the invention the purpose of this utility model provides a kind of multifunctional ruler, is used to solve the problem that it is inconvenient that common ruler is drawn.

For achieving the above object, the utility model multifunctional ruler comprises a quadrangle transparent plastic material, and quadrangle plastic plate diagonal is perpendicular, offers two slits along diagonal, and two slits are according to rectangular axes marking scale; Article two, the diagonal slit is divided into four triangles to the quadrangle plastic plate, and wherein two leg-of-mutton triangles are respectively 90 °, 60 ° and 30 °, and 60 ° of angles are adjacent; Two leg-of-mutton triangles are respectively 90 °, 45 ° and 45 ° in addition.

After adopting said structure, the user can normally use ruler measurement length and angle, also can draw out common right angled triangle, isosceles right triangle, quadrangle and draw out rectangular axes by the diagonal that vertically communicates according to the ruler structure.

The utility model has the advantages that: simple in structure, convenient and practical, efficiently convenient, measure accurately, can guarantee the basic function measured, can accurately draw out multiple figure commonly used again.

Description of drawings Fig. 1 is the overall structure schematic diagram of the utility model multifunctional ruler.

The specific embodiment as shown in Figure 1, the utility model multifunctional ruler comprises a quadrangle transparent plastic material 1, quadrangle plastic plate 1 diagonal is perpendicular, offers 2, two slits 2, two slits according to rectangular axes marking scale along diagonal; Article two, diagonal slit 2 is divided into four triangles to quadrangle plastic plate 1, and wherein two leg-of-mutton triangles are respectively 90 °, 60 ° and 30 °, and 60 ° of angles are adjacent; Two leg-of-mutton triangles are respectively 90 °, 45 ° and 45 ° in addition.
