Embodiment Construction

[0015] Such as figure 1 A specific embodiment of the present invention is proposed as shown, a plotter for drawing tangent curves, including a support in the shape of a "7", the top of the support 1 is connected to a support frame 2 arranged horizontally, and the support frame 2 It is rectangular parallelepiped and has a hollow structure. The upper end of the support frame 2 and the connecting end with the bracket 1 are provided with a vertically folded groove, and a rectangular parallelepiped sliding block 3 is embedded in the groove. The sliding block plate 3 is vertically connected with the support frame 2, and one side of the sliding block plate 3 is connected with the end of the support 1 and can slide linearly along the support 1. In this embodiment, the sliding block plate 3 There is a chute on the top, and the end of the bracket 1 is provided with a connecting piece that can be embedded in the chute, and then the sliding plate 3 is realized by moving in a straight line...

Abstract

The invention provides a plotting instrument for plotting a tangent curve. The plotting instrument comprises a bracket, wherein a support frame is connected with the top end part of the bracket; a sliding block plate is embedded at the upper end of the support frame; one side of the sliding block plate is connected with the end of the bracket; a gear rack is arranged on the other side of the sliding block plate and is meshed with a driving gear; the driving gear is provided with a rotary shaft; a transmission gear is arranged on the rotary shaft and is meshed with a rolling gear; a first belt pulley is connected with a second belt pulley; the second belt pulley is connected with a paintbrush driving gear; the paintbrush driving gear is meshed with a paintbrush transmission gear; a paintbrush frame is connected onto the paintbrush transmission gear; and a paintbrush is arranged on the paintbrush frame. The plotting instrument realizes plotting of the tangent curve through a tool, overcomes the defects of plotting through manual painting or a complex method, is simple in step, convenient and fast, high in precision, easy to manufacture and realize, and is an ideal plotting tool for teaching and learning.

Description

technical field [0001] The invention relates to a curve drawing tool, in particular to a plotter for drawing tangent curves. Background technique [0002] At present, there is no teaching aid specially used to accurately draw tangent curves on the market. When teachers describe the knowledge of the tangent function, they usually use the tangent curve diagram to explain the properties of the tangent function, etc., and the drawing of the tangent curve is either roughly hand-drawn or drawn by various complicated methods. No matter which drawing method has the following Disadvantages: The drawing operation is difficult, time-consuming, and low-precision. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a plotter for drawing tangent curves. The plotter implements tools to draw tangent curves, and changes the defects of existing hand drawing or complex methods. The drawing steps are simple, convenient and quick, Wi...
