Abstract
The utility model discloses a ruler. Two ruler bodies are connected by a rotary axle, an angle protractor is arranged on the rotary axle, a horizontal tube is arranged on the ruler body, and the end parts of the ruler bodies are provided with a needle and a draw pen and an exclusive used bobbin for drawing ellipse. The utility model collects a ruler, a folding rule, a level ruler, a triangle ruler, an angle protractor, a height measuring device, a compass and an ellipsograph as integration, which is a multi-functional teaching aid and a surveying and mapping tool with easy use.
Description
Technical field the utility model relates to drawing instrument, is specially adapted to teaching aid, also can be used as surveying and mapping tool.
Background technology drawing instrument commonly used at present has ruler, set square, protractor, compasses etc., and these instrumental functions are single, and many inconvenience are arranged in the use.
The summary of the invention the purpose of this utility model is exactly that a kind of new scale will be provided, and it can overcome the problem of existing drawing instrument function singleness effectively.
The purpose of this utility model is achieved in that scale has two blades, and two blades form rotating shaft at the end points place, and the other end of a blade is installed the rule pin, and the other end of another blade is installed paintbrush.
As a kind of improvement project of the present utility model be: described rotating shaft place equipped amount hornwork.
As the further improved plan of the utility model be: on the described blade bobbin is housed.
As the utility model further improved plan be: on the described blade horizontal tube is housed.
The utility model is because with the formation rotating shaft that crosses of two blades, and rule pin and paintbrush are installed in the other end respectively, thereby the utility model can be made ruler, folding rule and compasses and uses; The utility model is because at rotating shaft place installation hornwork, thereby the utility model can be drawn, take measurement of an angle; The utility model is also owing to be equipped with bobbin on one ruler body end, thereby the utility model can be drawn ellipse; The utility model is also owing to be equipped with horizontal tube on one's body at one ruler, thereby the utility model can carry out measuring height.
Description of drawings Fig. 1 is a front view of the present utility model; Schematic diagram when Fig. 2 is the utility model mapping angle; Schematic diagram when Fig. 3 is the utility model picture ellipse; Schematic diagram when Fig. 4 is the utility model measuring height.Below in conjunction with accompanying drawing the utility model is further specified.
Specific embodiment Fig. 1 shows the structural principle of scale described in the utility model, the 2 usefulness rotating shafts 1 of two blades is connected can constitute ruler and folding rule, advises pin 4, can draw circle at another blade 2 other ends dress paintbrush 5 at a blade 2 other ends dress; Adorn a protractor 7 in rotating shaft 1, the angle of rotatable blade 2 is drawn angle or angulation; Adorn a bobbin 3 in a blade 2 ends, line is pulled out hang over that line segment length is adjusted in another blade 2 ends and rule pin width can be drawn ellipse; On blade 2, adorn horizontal tube 6, can survey the height of level, picture horizontal line or measurement building.The course of work of the present utility model is as follows:
Draw straight line or horizontal line: the utility model scale can be directly used in the picture straight line and measure length, if one of the blade 2 of scale Rotate 180 °, be the ruler that range doubles; Press horizontal level shown in the horizontal tube 6 on the blade 2, can draw horizontal line or measurement level.
Survey, draw 180 ° with interior any angle: one of blade 2 is rotated to an angle, can draw 180 ° along the scale both sides with interior any angle.Alignd with its summit for the treatment of angle measurement in scale rotating shaft 1 center, again two blades 2 are alignd with the arm of angle, directly read angle on the protractor 7.
Draw circle with oval: it is identical with general common compasses operation to use the utility model scale to draw circle.Only the cotton rope on the bobbin 3 of a blade 2 ends need be pulled out when drawing ellipse and hang over another blade 2 ends, adjust line length and chi pin width, required ellipse can draw.
Survey the picture horizontal line, survey high, survey wide: by means of the horizontal tube on the scale described in the utility model 6, the level of object be can directly measure or horizontal line or vertical line on blackboard, drawn, if measure the height of high-lager building, blade 2 adjustment levels with scale band horizontal tube 6, adjusting another limit with ray method makes it align with the height of building, read angle from the protractor 1 of scale,, can calculate the height of building again according to triangle knowledge.If survey the width in river, its method is similar with the high principle of survey.
State when Fig. 2 shows scale described in the utility model mapping angle; Fig. 3 shows scale described in the utility model and draws state when oval, the state when Fig. 4 shows scale measuring height described in the utility model.
