Description

A kind of multifunctional drawing pen
Technical field
The utility model relates to a kind of transmission mechanism, belongs to mechanical design field.
Background technology
In drawing in classroom, it is too much that teacher and classmates usually face drawing tool, the situation that mapping is inconvenient.Linkage, by improving compasses and protractor, is combined with bearing by this drawing pen, to realize the function basic operation of setting-out, picture circle, angulation combined; Meanwhile, this drawing pen is easy to carry, and mapping has certain rapidity, accuracy, convenience.
Utility model content
The purpose of this utility model is that design one can improve classroom drawing efficiency, compasses are combined with protractor, realize pointer angulation, disposablely complete horizontal line, be the drafting of the line of any number of degrees with horizontal line angle, facilitate the drawing instrument of classmate and teacher, multi-functional requirement can be realized.
For achieving the above object, the technical solution of the utility model is:
A kind of multifunctional drawing pen comprises: mobile jib (1), connecting rod (2), support bar (3), lasso (4), bolt (5), fixed pointers (6), movable pointer (7), connector (8), screw I (9), nut (10), bearing (11), supporting disk (12), bearing holder (housing, cover) (13), pad (14), screw II (15), dial plate (16), paintbrush (17).
Connecting rod (2) and the connector (8) of above-mentioned multifunctional drawing pen form a movable auxiliary, connector (8) with dial plate (16) for tight bolt is connected, dial plate (16) with lasso (4) for tight bolt is connected, lasso (4) with bearing holder (housing, cover) (13) for tight bolt is connected, bearing holder (housing, cover) (13) and bearing (11) are interference fit, and bearing (11) and mobile jib (1) form a revolute pair; Mobile jib (1), dial plate (16), connector (8), connecting rod (2), support bar (3), paintbrush (17) form compasses; Dial plate (16), fixed pointers (6), movable pointer (7) form a protractor; Be joined together by connector (8) between compasses and protractor; Connecting rod (2) and support bar (3) form a movable auxiliary, and connecting rod (2) and connector (8) form a movable auxiliary; Mobile jib (1) and movable pointer (7) form a revolute pair, and mobile jib (1) and bearing (11) form a revolute pair; The connected mode of mobile jib (1) and fixed pointers (6) is for glued joint.
The utility model is a kind of multifunctional drawing pen, and its advantage and effect are:
Paint at any angle all more convenient, blackboard surface both hands are mapped, and there is not dead angle.Integrate the function of picture angle, compasses construction, ruler, function is more complete.Mapping and measuring technique combine together.Meanwhile, mechanism is simple, and stability is high, and is easy to carry about with one.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is partial enlargement elevation cross-sectional view of the present utility model.
Fig. 3 is partial enlargement side cutaway view of the present utility model.
In figure, concrete label is as follows: 1---mobile jib; 2---connecting rod; 3---support bar; 4---lasso; 5---bolt; 6---fixed pointers; 7---movable pointer; 8---connector; 9---screw I; 10---nut; 11---bearing; 12---supporting disk; 13---bearing holder (housing, cover); 14---pad; 15---screw II; 16---dial plate; 17---paintbrush.
Detailed description of the invention
In this mechanism, connecting rod (2) and support bar (3) form a movable auxiliary, any one or several clockwise or counterclockwise rotation around mobile jib (1) in connecting rod (2) and support bar (3) can drive the rotation of dial plate (16), (16) have scale value with dial plate, streak the size of the angle of fixed pointers (6) by reading dial plate (16) card, income value is the size of the angle that paintbrush (17) is walked around.Describe concrete function of the present utility model in detail below in conjunction with accompanying drawing and specific implementation method, be used for explaining the utility model in this schematic enforcement of the present utility model and explanation, but not as to restriction of the present utility model.
Example 1: the drawing of generic linear
When mobile jib (1) is perpendicular to blackboard surface, tighten screw II (15) thus fix dial plate (16), paintbrush (17) is contacted with blackboard surface, when support bar (3) swings, paintbrush (17) can draw straight line at blackboard surface.
Example 2: horizontal drawing and measurement
When mobile jib (1) is perpendicular to blackboard surface, due to Action of Gravity Field, movable pointer (7) and dial plate can rotate around mobile jib (1), finally pointing to is straight down, write down now fixed pointers (6) indication number of degrees on dial plate (16), rotary supporting rod (3) then can drive the rotation of dial plate (16), observe fixed pointers (6) at the upper indication number of degrees of dial plate (16), when front and back twice read the number of degrees difference be 90 degree time, tighten screw II (15), stretch support bar (3) makes paintbrush (17) move on blackboard surface, obtain straight line, drawn straight line is horizontal line.Otherwise, can verify whether straight line is horizontal line.
Example 3: be drawing and the measurement of the line of any number of degrees with horizontal line angle
When mobile jib (1) is perpendicular to blackboard surface, the end points of the lower end of mobile jib (1) and paintbrush (17) is placed on same horizontal line, rotary supporting rod (3), tighten screw II (15), stretch support bar (3) makes paintbrush (17) move on blackboard surface, obtains straight line.Read by dial plate (16) and fixed pointers (6) size that support bar (3) rotates front and back dial plate (16) rotation angle, this angle is institute's drawing beeline and horizontal angle.Thus, then can draw with horizontal line angle is line at any angle.Otherwise, the angle between straight line and horizontal line can be measured.
Example 4: the drawing of random angle and measurement
When mobile jib (1) is perpendicular to blackboard surface, the lower end of mobile jib (1) is placed on the summit of institute's angle measurement, the end points of paintbrush (17) is placed on a limit of institute's angle measurement, rotary supporting rod (3) makes paintbrush (17) be positioned on another limit of institute's angle measurement, read by dial plate (16) with fixed pointers (6) size that support bar (3) rotates front and back dial plate (16) rotation angle, this angle is the angular dimension of institute's angle measurement.Otherwise, also can realize the drawing of random angle.
