Abstract
The utility model relates to a drawing instrument, in particular to a parallel drawing instrument which comprises a square template as a main body which is arranged with scales in the circumference of the template. The utility model is characterized in that the template is provided with a mould frame and a protractor which are used for drawing screw thread sectional plane, a form and position tolerance, a chamfering line, a sectional plane line, roughness, a dimension borderline and a baseline. The mould frame and the protractor can be used as a triangle. The template is also provided with a thin scale mark which is convenient for directly measuring length and drawing lines. The thin scale mark is provided with a pen inserting hole and a roller which is easy for dragging and drawing frame lines. The utility model has simple structure, convenient use, complete function and high accuracy and is a necessary drawing instrument for a technician.
Description
The utility model relates to a kind of drafting instrument, specifically a kind of translation plotter.
At present, the chi type drawing instrument that people use always mainly contains two types, and a kind of is two chi type translation plotters, and a kind of is with ruler, set square combination.This two classes instrument in use all exists some problems, such as two chi type translation plotters in its two chis intersection scale divergence, thereby the function of shortage amount picture combination, and ruler, set square are combined as scattered, bad keeping, be not easy parallel dragging, and the two all exists the problem that need join template in use in addition.
The purpose of this utility model is to provide a kind of collection two chi type translation plotters, and ruler, set square and drawing template advantage are the translation plotter of one.
In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme: the square template (1) that is carved with scale around the design one, template (1) is provided with and is used to draw form, form and position tolerance, the chamfering line, hatching, roughness, extension line, benchmark, framed and protractor as set square, and be provided with and be convenient to directly measure length, the thin real graduation mark that draws lines, on thin real graduation mark, be provided with pen plughole, and be provided with the roller that is easy to drag and be convenient to the frame line, roller is the cylinder that two ends are provided with the boss that lands, be installed in the fitting recess of template (1) by nylon bearing (5), corresponding with roller on template (1), be provided with in the chi frame, be provided with size scale in interior chi frame surrounding.Draw for convenience the system ruling, be provided with by line-spacing adjuster seat (3), locating pin (7), flat spring (8) and roller central authorities in the central authorities of roller and have the line-spacing adjuster that the cannelure of little taper hole is formed.
Owing to adopted technique scheme, it is the goal of the invention of one that the utility model has realized collecting two chi type translation plotters, ruler, set square and drawing template advantage, it is simple in structure, and is easy to use, multiple functional, accuracy is high, is the drawing instrument of technical staff's indispensability.
Description of drawings:
Accompanying drawing 1 is the utility model schematic top plan view
Accompanying drawing 2 is concrete structure (vertical section of accompanying drawing 1) schematic diagrames of the utility model roller portion
Embodiment:
Accompanying drawing has been described an embodiment of the present utility model.Referring to accompanying drawing, the utility model is made up of template (1) and roller two parts, template (1) is the square plate that is carved with scale around, which is provided be used to draw form, form and position tolerance, chamfering line, hatching, roughness, extension line, benchmark, as the framed and protractor of set square, and be provided with and be convenient to the thin real graduation mark directly measuring length, draw lines, on thin real graduation mark, be provided with pen plughole, and be provided with the fitting recess that is used to assemble roller, present embodiment is two, two mounting grooves are orthogonal, are parallel to template (1) both sides respectively.
Roller is the cylinder that two ends are provided with the boss that lands, and is installed in the fitting recess of template (1) by Buddhist nun's logical sequence bearing (5), and is corresponding with roller, and chi frame in being provided with on template (1) is provided with size scale in inside dimension frame surrounding.Draw the system ruling for convenience, central authorities at roller are provided with by line-spacing adjuster seat (3), locating pin (7), flat spring (8) and roller central authorities have the line-spacing adjuster of the cannelure composition of little taper hole, the line-spacing adjuster can slide in the narrow groove of little length of roller top template (1), conelet hole on the roller central annular groove becomes branch layouts such as difference, the picture system of being mainly used in ruling, when the line-spacing adjuster moves to when making locating pin (7) relative with the left side first cannelure, the line-spacing of then drawn system ruling is roller two ends boss outer circumference/left side first cannelure epicone hole count that lands.In order to prevent roller at the axis direction play, improve the wearability of roller installation shaft, be provided with small ball (6) bottom the installing hole of nylon bearing (5) and between the installation shaft axle head of roller.
In order to use this plotter to draw the mutually perpendicular straight line of system easily, the utility model has designed two rollers (2), (4), and two orthogonal, is parallel to template (1) two outer edge respectively.
