Abstract

The utility model relates to a multi-purpose drawing sector, which comprises a main ruler that is combined by a ruler and a protractor, and a movable ruler, wherein, the circle center of the protractor of the main ruler is provided with a shaft hole in which a shaft core and a shaft sleeve are installed, and the shaft sleeve is provided with the movable ruler and a gravitational pointer which always points vertically to the ground at the head part in use. When matched with the gravitational pointer for drawing, the ruler, the protractor and the movable ruler of the main ruler can draw straight lines of arbitrary angles, perpendicular lines, parallel lines, circular lines and circle arc lines. Compared with the existing multi-purpose sectors, the multi-purpose drawing sector has the advantages of more functions, simple operation and higher drawing speed, and is more suitable for teaching and engineering drawing work.

Description

Use drawing ruler and gauge more
The utility model relates to a kind of drawing ruler and gauge, particularly a kind of drawing ruler and gauges of using more.
Existing teacher and the engineering art designer instrument of being used always of drawing on the object perpendicular to ground such as blackboard, metope and billboard has ruler, set square, compasses and protractor etc., it all is the single specific purpose tool of function of use, the by turns access times of each instrument are frequent in the use, influence mapping speed, and how number of packages is to using and carrying and make troubles.China's utility application number: 90226387.0 disclose a kind of multipurpose ruler rule, it combines ruler and protractor, be connected with another ruler at the protractor circle centre position with axle, two ruler end portions are provided with respectively compass foot pin and movable pen clip are installed, thereby realize the collection ruler, compasses, multiple geometric construction instrumental function such as protractor is in the multipurpose ruler rule of one, give and make graphic operation and carry to bring convenience, but when this ruler is in use run into picture straight line perpendicular to the ground and horizontal line and arbitrarily angled PAR, also must be by vertical collimator or other aid, method could realize.
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of many drawing functions of use that can realize existing multipurpose ruler rule is provided, again can be not by other aid realization picture with the use of the vertical straight line in ground, horizontal line and arbitrarily angled PAR function and one, the drawing ruler and gauge of using easy to carry more.
According to above-mentioned purpose, embodiment of the present utility model is: comprise the main scale that is combined into by ruler and protractor, adjustable rule, be fixed with the compass foot pin in the end of ruler, the adjustable rule end is provided with a circle hole sleeve on the axle sleeve of protractor center of circle axis hole axis core, is slidingly matched with axle sleeve, and other end head is fixed with a movable pen clip, it is characterized in that being positioned on the axle sleeve of the protractor center of circle axis hole axis core gravity pointer also is housed, be slidingly matched with axle sleeve; The protractor upper surface is distributed with by the numerical marker line of compass foot pin with the big down scale of distance of separation between the movable pen clip head along the semicircle outside.
The utility model is owing to adorned mobilizable gravity pointer on the axle sleeve of protractor center of circle axis hole axle core, point to all the time with the vertical feature in ground by the gravity tester needle section during use, utilize on the main scale protractor and ruler to cooperate and to draw straight line, vertical line, the parallel lines at any angle, utilize adjustable rule by the open distance of the adjusting of the distance scale numerical value on the protractor, can draw the circular arc and the circle of relevant radii with ruler.Compare with prior art multipurpose ruler rule, it is many to have function, simple to operation, has improved plotting speed simultaneously, is more suitable for using in teaching and engineering mapping.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the backsight structural representation of Fig. 1.
Fig. 3 is that the A-A of Fig. 1 is to cutaway view.
Fig. 4 is the partial enlarged drawing at Fig. 3 " I " position.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1 and Figure 2, how this comprises main scale (1) with drawing ruler and gauge, adjustable rule (2), gravity pointer (3).Main scale (1) is made up of ruler and protractor integrator, is fixed with compass foot pin (9) in the ruler end of main scale (1) with bolt (10), draws bowlder and plays center of circle positioning action.Semicircle center at main scale (1) protractor has an axis hole, a core (4) is installed in the axis hole, its structure is seen Fig. 3, shown in Figure 4, axis hole bottom surface and axis hole close-fitting are passed in the lower part of axle core (4), its top is with an axle sleeve (12), after adjustable rule (2) passes guide groove below the main scale height hornwork, be installed on the bottom of axle sleeve (12) by the circular hole of tail end, same axle sleeve (12) is slidingly matched, the tail end of gravity pointer (3) also has a circular hole, be installed on the top of axle sleeve (12), same axle sleeve (12) is slidingly matched, and is provided with a spacer at axle sleeve (12) middle part, and adjustable rule (2) and gravity pointer (3) are separated, the head of axle core (4) have an axle cap by screw thread be mated screw after, axle sleeve (12) is pressed on one's body the main scale.Be fastenedly connected with the movable pen clip (7) of a clamping paintbrush (8) at the other end head of adjustable rule (2) with bolt (6), paintbrush (8) can be chalk, wax crayon, pencil etc. according to instructions for use.Adjustable rule (2) has a bolt (5) near protractor semicircle outer side edges along the position, the same pressing plate in its lower end (11) is fixedly connected, have groove (1-1) in main scale (1) bottom surface along position, protractor semicircle outer, one end of pressing plate (11) is arranged in groove (1-1), after screwing bolt (5), pressing plate (11) just is fixed on adjustable rule (2) on one's body the main scale.
The ruler setting-out side plane of main scale (1) is parallel with the horizontal line of protractor center of circle cross centre line, the ruler upper surface is evenly distributed with corresponding centimeter scale by the setting-out side by blade length numerical values recited and indicates line, the protractor upper surface is distributed with angle index and indicates line along the semicircle inboard, the protractor upper surface is distributed with by the numerical marker line of compass foot pin (9) with the big down scale of distance of separation between movable pen clip (7) head along the semicircle outside.
During use: at blackboard, metope, when mapping setting-out on the surface of vertical grounds such as billboard, ruler with the same main scale of adjustable rule (2) (1) closes up back fastening bolt (5) earlier, at this moment, because the same axle sleeve of gravity pointer (3) (12) is to be slidingly matched, so gravity pointer (3) head is vertical all the time directed towards ground under the self gravitation effect, adjust main scale (1) protractor position by moving, gravity pointer (3) is referred on the angle index line numerical value that corresponding setting-out angle requires, utilize the ruler of main scale (1) straight line at any angle that can conveniently draw in 0~360 °, the straight line of vertical ground, horizontal line and a certain PAR.When drawing circle and circular arc, by drawn circle and the requirement of arc radius numerical value, adjustable rule (2) is opened, after making the corresponding numerical scale line of scale index line amount of alignment hornwork semicircle outer upper surface on it, fastening bolt (5) is fixing with adjustable rule (2), the compass foot pin (9) that makes the ruler end then is in the surperficial circle centre position location of drawn circle and circular arc, the paintbrush (8) that promptly available adjustable rule (2) is gone up dress the draw circle and the circular arc of corresponding size.
