In order to solve the deficiencies of the prior art, the present invention provides a device for drawing a diagram of square electrical parts.

The technical scheme adopted in the present invention is: a device for drawing a diagram of square electrical parts, including a guide block, a Leroy triangle block, a drive block, and a line drawing block;

The guide block includes a square plate, a first square ring, and a second square ring. The lengths of the outer sides of the three are the same. The length of the inner side of the second square ring is smaller than the length of the inner side of the first square ring. The three are overlapped in turn, so that the outer sides of the three are aligned and fixed, and a square annular guide groove is formed on the inner side;

The Leroy triangle block takes each vertex of the equilateral triangle as the center, the side length of the equilateral triangle as the radius, and an arc is drawn between the other two vertices, and the curved-sided triangle block enclosed by the three arcs is the Leroy triangle. The block, the center of the Leroy triangle block is provided with a circular hole, and the inner teeth are arranged around the circular hole. The side length of the equilateral triangle is equal to the side length of the square annular guide groove. In the groove, the Leroy triangle block can rotate freely in the square annular guide groove, and the three vertices of the Leroy triangle block always abut against the square annular guide groove;

The drive block includes a central shaft and a gear, the central shaft is fixedly arranged in the center of the square plate, the gear is rotatably arranged on the central shaft, the teeth on the gear are engaged with the internal teeth in the Leroy triangle block, and the energy is arranged on the gear. The handle that drives the gear to rotate, turn the handle, and the gear drives the Lelow triangle block to rotate in the square annular guide groove. Since the center of the Lelow triangle block does not coincide with the center of the gear, the Lelow triangle block rotates eccentrically relative to the gear;

The line drawing block includes a drawing rod and a line drawing pen, one end of the drawing rod is fixed on the Leroy triangle block, the position of the drawing rod is located on any midline of the Leroy triangle block, and the other end of the drawing rod extends out of the guide block to draw the line. A line drawing pen perpendicular to the drawing stick and pointing to the picture is set on the stick.

Further, in order to conveniently fix the guide block on the drawing paper or the blackboard, a suction cup is provided on the outer side of the square board.

Further, in order to facilitate portability and reduce the peripheral size, the drawing rod is a telescopic rod, and the cross-section of the telescopic rod is non-circular, so that each telescopic section of the telescopic rod can only be extended relative to each other but cannot be rotated relatively, and the top of the telescopic rod is provided with a Line drawing pen.

Further, in order to accurately determine the size of the drawn square, a scale line is provided on the drawing rod.

The working process of the present invention is as follows: firstly, the present invention is fixed on the drawing paper or blackboard by using a suction cup, according to the size of the square to be drawn, the position of the line drawing pen is determined by using the drawing rod and the scale line on the drawing rod, and the handle is rotated, and the gear drives the drawing pen. The three vertices of the Leroy triangle block always abut against the square annular guide groove, that is, the trajectory of the three vertices of the Leroy triangle block is a square, The Luo triangle block is rotated with an animation rod. The drawing rod and the line drawing pen on the drawing rod correspond to each vertex of the Le Luo triangle block, and the trajectory of the line drawing pen is a square.

The beneficial effects of the invention are as follows: the invention can draw a square conveniently at one time, the operation is convenient, the drawing is fast, the graphics are standardized, and the squares of different specifications can be drawn.

Detailed ways

The present invention will be further described below with reference to the accompanying drawings.

A device for drawing a diagram of square electrical parts, comprising a guide block 1, a Leroy triangle block 2, a drive block, and a line drawing block;

The guide block 1 includes a square plate 11 , a first square ring 10 , and a second square ring 9 . The inner side is long, and the three are overlapped in turn, so that the outer sides of the three are aligned and fixed, and a square annular guide groove is formed on the inner side;

The Leroy triangle block 2 takes each vertex of the equilateral triangle as the center of the circle, and the side length of the equilateral triangle as the radius, and an arc is made between the other two vertices, and the curved triangle block surrounded by the three arcs is Leroy. A triangular block, a circular hole is opened in the center of the Leroy triangle block 2, and internal teeth 3 are arranged around the circular hole. In the annular guide groove, the Leroy triangle block 2 can rotate freely in the square annular guide groove, and the three vertices of the Leroy triangle block 2 always abut against the square annular guide groove;

The drive block includes a central shaft 5 and a gear 6, the central shaft 5 is fixedly arranged in the center of the square plate 11, the gear 6 is rotatably arranged on the central shaft 5, and the teeth on the gear 6 are the same as the internal teeth in the Lelot triangle block 2. The teeth 3 are engaged, and the handle 4 that can drive the gear to rotate is set on the gear 6. When the handle 4 is turned, the gear 6 drives the Lelow triangle block 2 to rotate in the square annular guide groove. Because the center of the Lelow triangle block 2 and the gear The centers of 6 do not coincide, and the Leroy triangle block 2 rotates eccentrically relative to the gear 6;

The line drawing block includes a drawing rod 7 and a line drawing pen 8. One end of the drawing rod 7 is fixed on the Leroy triangle block 2, the position of the drawing rod 7 is located on any midline of the Leroy triangle block 2, and the other side of the drawing rod 7 is located on the center line of the Leroy triangle block 2. One end protrudes from the guide block 1, and the drawing rod 7 is provided with a line drawing pen 8 which is perpendicular to the drawing rod and points to the screen.
