Detailed description of the invention
Below in conjunction with the accompanying drawing in example of the present invention, be clearly and completely described the technical scheme in example of the present invention, obviously, described example is only the present invention's part example, instead of whole examples.Based on the example in the present invention, those of ordinary skill in the art, not making the every other example obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Fig. 1 ~ 4, a kind of ellipsograph, comprise base 13, base 13 is connected with column 14, column 14 is connected with matrix 15, matrix 15 is connected with push rod 16, push rod 16 two ends are connected with alignment pin, the termination of alignment pin is arranged in the chute 8 of the first support bar 12 and the second support bar 7, one end of second support bar 7 is hinged on matrix 15, one end is connected with the second intermediate mass 19, handwheel 6, be connected by bolt between second intermediate mass 19 and the second turning cylinder 5, second turning cylinder 5 is connected with the second adjusting rod 4, second adjusting rod 4 is connected with the second transmission rod 3, first support bar 12 one end and matrix 15 are hinged and connected, the other end is connected with the first intermediate mass 20, screw bolt passes fixed cover 18, first intermediate mass 20 and the first turning cylinder 11, first turning cylinder 11 is connected with the first adjusting rod 10, first adjusting rod 10 is connected with the first transmission rod 9, first transmission rod 9, second transmission rod 3 is hinged and connected part and is provided with paintbrush connector 21.
First turning cylinder 11 and oval semi-minor axis that axial line distance h between the first transmission rod 9 is equivalent to.Preferably, described first adjusting rod 10 comprises two parts composition, Part I is the screw rod 10-1 be connected with the first turning cylinder 11, Part II is the connector 10-2 be connected with the first transmission rod 9 screw thread, screw rod 10-1 is connected by pin with connector 10-2, like this, by rotating the first adjusting rod 10, change the first turning cylinder 11 and axial line distance between the first transmission rod 9, and then oval semi-minor axis length can be changed.
Use procedure of the present invention is as follows: be fixed on by paintbrush 1 on paintbrush connector 21, base 13 fixes, rotate handwheel 6, handwheel 6 drives the second turning cylinder 5 to rotate, second turning cylinder 5 drives the second transmission rod 3 to rotate by the second adjusting rod 4, second transmission rod 3 drives the first transmission rod 9 to rotate, first transmission rod 9 drives the first turning cylinder 11 to rotate by the first adjusting rod 10 again, in the process of rotating, second transmission rod 3 can slide along the hole on the second adjusting rod 4, first transmission rod 9 can slide along the hole on the first turning cylinder 11, and then paintbrush 1 is passed by an elliptical path.According to actual needs, if need to draw incomplete ellipse, can be realized by rotation hand wheel 6.
In addition, hinged by straight pin between first support bar 12, second support bar 7 and matrix, push rod 16 can slide along matrix 15, by regulating straight pin and push rod 16, and then the angle that can change between the first support bar 12, second support bar 7, also just change the angle of the first adjusting rod and the second adjusting rod, and then adjust oval major semiaxis.
As preferably, described matrix 15 is provided with column fixing hole 22, and slot in matrix 15 one end, cell body two ends are provided with fastening bolt holes 17.After such setting, the height of matrix 15 can be adjusted, and then the height of paintbrush 1 can be adjusted.In addition, be connected by fastening bolt between paintbrush 1 and paintbrush connector 21, unclamp fastening bolt, mechanism can rotate around column 14, thus changes the drawing direction of paintbrush 1.
As a step is preferred again, be threaded between described second turning cylinder 5 and the second adjusting rod 4, between the first turning cylinder 11 and the first adjusting rod 10.
Described paintbrush connector 21 is connected with eccentric adjusting bar 2, and eccentric adjusting bar 2, second transmission rod 3 and the first transmission rod 9 are hinged and connected.The present invention does not need, to the downward pressure of ellipsograph, only to need rotation hand wheel just, because drawing in oval process, departing from adjusting rod can automatically to eccentric adjusting bar 2 one power, thus makes eccentric adjusting bar 2 to the downward active force of one, paintbrush.
Wherein, suppose that the pin joint of eccentric adjusting bar 2, second transmission rod 3 and the first transmission rod 9 is revolute pair A point, then the track of A point is planar oval, wherein major semiaxis
Semi-minor axis b=h,
Now the equation of locus of revolute pair A is
The foregoing is only preferred embodiments of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
