Abstract

The utility model discloses a novel combined mechanism compass which comprises a sucking disc, a pointer sliding block, a compass supporting rod, connecting rods, two compass turning poles and a positioning sliding block, wherein the compass supporting rod, the pointer sliding block, the connecting rods, one compass turning pole and the positioning sliding block constitute an elliptical mechanism; the pointer sliding block, the positioning sliding block and the two compass turning poles constitute a parallel mechanism. The pointer sliding block slides along a sliding groove in the compass supporting rod and drives the compass turning poles and the connecting rods to rotate, and a radius can be determined according to scales on the compass supporting rod; at the same time, the two compass turning poles ensure that a paintbrush connected to the positioning sliding block is always perpendicular to a drawing plane; the sucking disc adsorbs a blackboard plane or a principal plane, and an angle can be determined according to an angle scale at the lower end of the compass supporting rod; the compass supporting rod is rotated around a rotating shaft at the upper end of the sucking disc to drive the paintbrush to draw a picture. According to the novel combined mechanism compass, the radius and the angle can be directly determined when a circle and an arc are drawn, the positioning is accurate, the structure is compact, the operation is convenient, and higher popularization and application values are realized.

For solving the problems of the technologies described above, the technical solution adopted in the utility model 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, around rotating shaft, rotate compasses pole, by compasses bull stick, drive the paintbrush of installing on positioning sliding block can realize the angle graphing arranging by size scale value and angle scale.

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 form 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.

The utility model has the advantages that: 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.
