Description
Technical Field
The invention relates to a mathematical drawing tool, in particular to a mathematical ellipse drawing tool.
Background
Mathematics is a subject of studying concepts such as quantity, structure, variation, space, and information, and belongs to a form science from a certain point of view. Mathematicians and philosophies have a range of views on the exact scope and definition of mathematics. In the prior art, drawing is performed in mathematics learning, most drawing tools draw straight lines, circular arcs and the like, but the drawing of an ellipse is troublesome, and a plurality of auxiliary circles and auxiliary lines need to be drawn by using compasses to draw the ellipse, so that an improvement space exists.
Disclosure of Invention
It is an object of the present invention to provide a mathematical ellipse drawing tool for solving the above problems.
The invention realizes the purpose through the following technical scheme:
the invention comprises a bracket, a bracket pulley, a bracket ring, a turntable, a sleeve, a telescopic rod, a spring seat, a spring, a movable pulley and a loop rope, wherein the bracket ring is fixedly arranged in the middle of the bracket, the bracket pulley is arranged at two ends of the bracket, the turntable is rotatably connected with the middle of the bracket ring, the sleeve is fixedly arranged on the upper end surface of the turntable, the telescopic rod penetrates through the sleeve and can move, the spring is a tension spring, the spring seat is fixedly arranged at one end of the telescopic rod, one end of the spring is fixedly connected with one end of the sleeve, the other end of the spring is fixedly connected with the spring seat, the movable pulley is arranged at the other end of the telescopic rod, the loop rope is annular, the loop rope is sleeved between the two bracket pulleys and the movable pulley, and the middle of the movable pulley is a through hole, the through hole is penetrated through the pen point of the painting brush.
Preferably, a bearing is arranged between the turntable and the support ring.
The invention has the beneficial effects that:
the invention is a mathematical ellipse drawing tool, compared with the prior art, the invention does not need to draw auxiliary lines, can draw ellipses at one time, adopts the change of the length of the loop rope, thereby drawing ellipses with different sizes, is convenient and rapid to use, and has popularization and application values.
Drawings
Fig. 1 is a schematic structural view of the present invention.
In the figure: 1-bracket, 2-bracket pulley, 3-bracket ring, 4-turntable, 5-sleeve, 6-telescopic rod, 7-spring seat, 8-spring, 9-movable pulley and 10-rope.

Preferably, a bearing is arranged between the turntable 4 and the support ring 3.
As an improvement, the length of the bracket can be adjusted.
The working principle of the invention is as follows:
through inserting the drawing pen in the middle part at movable pulley 9 for the telescopic link 6 is tightened the noose 10 owing to the effect of spring, forms oval handwriting along with the rotation of telescopic link, if draw the length that the ellipse of equidimension can be through changing the length of noose, the length of support and realize drawing the ellipse of equidimension not.
The foregoing shows and describes the general principles and features of the present invention, together with the advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
