Abstract
The invention discloses novel combined mechanism compasses which comprise a suction cup, a pointer sliding block, a compasses supporting rod, a connecting rod, compasses rotary rods and a locating sliding block. An elliptical mechanism is composed of the compasses supporting rod, the pointer sliding block, the connecting rod, one compasses rotary rod and the locating sliding block, and a parallel mechanism is formed by the pointer sliding block, the locating sliding block and the two compasses rotary rods. The pointer sliding block slides along a sliding groove in the compasses supporting rod and drives the compasses rotary rods and the connecting rod to rotate, and the radius can be determined according to size scales on the compasses supporting rod. Meanwhile, the two compasses rotary rods guarantee that a drawing pen connected to the locating sliding block is perpendicular to a drawing plane all the time. The suction cup is attracted to a blackboard plane or a paper face, and the angle can be determined through an angle scale at the lower end of the compasses supporting rod. The compasses supporting rod is rotated around a rotary shaft at the upper end of the suction cup, and the drawing pen is driven to draw a figure. The radius and the angle can be directly determined when a circle and an arc are drawn, locating is accurate, the structure is compact, the operation is facilitated, and great application and popularization value is achieved.
Description
One, technical field
The present invention relates to a kind of compasses, particularly a kind of novel combined mechanism compasses that can directly determine radius and angle.
Two, background technology
Compasses are important tool that circle and circular arc are drawn in daily study and classroom instruction.Widely used traditional compasses are " people " character form structure, are made up of two compasses supporting legs, pin pin, the pen cap and paintbrush etc.For daily picture circle, draw circular arc, draw the situations such as Equal round, use traditional compasses construction, determine that arc radius and angle must rely on ruler, set square, the aids such as protractor could be realized, process is loaded down with trivial details, plotting error greatly, be inconvenient to use.
Three, summary of the invention
Technical problem to be solved by this invention is the deficiency for above-mentioned existence of the prior art, a kind of novel combined mechanism compasses are provided, and it can directly determine radius and angle, accurate positioning, and compact conformation, handled easily, have great application value.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of novel combined mechanism compasses, comprise sucker, compasses pole, connecting rod, indicator slide block, compasses bull stick, positioning sliding block, it is characterized in that: adsorb mutually with drawing plane the lower end of sucker, upper end is provided with rotating shaft, rotating shaft upper end connects by bearing with the lower end of compasses pole, the lower end of compasses pole is provided with angle scale, the middle and upper part of compasses pole is provided with the chute that can slide for indicator slide block, chute one side is provided with size scale, one end and the indicator slide block of two compasses bull sticks are hinged, the other end and positioning sliding block are hinged, one end of connecting rod and compasses pole bottom and between chute and angle scale position be hinged, in the other end of connecting rod and two compasses bull stick, a bar is hinged, the lower end of positioning sliding block is connected with the pen cap that paintbrush can be installed, the slip of indicator slide block drives two compasses bull sticks, link motion, and the size scale value of chute one side of indicating by indicator slide block is determined the position of positioning sliding block, rotate compasses pole around rotating shaft, drive the paintbrush of installing on positioning sliding block can realize the angle graphing arranging by size scale value and angle scale by compasses bull stick.
Described compasses pole, indicator slide block, connecting rod, compasses bull stick, a positioning sliding block form elliptical mechanism.
Described indicator slide block, positioning sliding block and two compasses bull stick composition parallel mechanism.
Described sucker (2) can be compass foot pin.
Described compasses bull stick (7) is two compasses bull sticks or single compasses bull stick.
Described connecting rod can be monotroded bar or double link; The bottom of double link one end and compasses pole and between chute and angle scale position be hinged, the double link other end and two compasses bull sticks are hinged respectively.
Advantage of the present invention is: while drawing circle and circular arc, can directly determine radius and angle, accurate positioning, and compact conformation, can fold, and handled easily has great application value.
