Embodiment Construction

[0017] The present invention is a kind of lead gauge, and its design principle sees Figure 5 . First, suppose there are two intersecting planes A and C in the three-dimensional space, and the intersection line is l 0 . Establish a plane B with a lead gauge and intersect plane B and plane A to obtain a straight line l 1 . Then, along with the rotation of the lead-out wire claws of the lead gauge, the plane B is decomposed into two, three or more overlapping small planes located in the same plane B. Finally, as two, three or more overlapping facets are sequentially unfolded, the plane B is extended from the first facet to the second facet, and then extended from the second facet to the third small plane, and so on, until a straight line l intersects with plane C 2 , realizing the extension of plane B and the intersection line l 1 around the intersection line l in plane B 0 Turn to intersection line l 2 .

Abstract

The invention relates to a tool for building and extending planes and rotating straight lines in a three-dimensional space, in particular to a line guide gauge. The line guide gauge suitable to fields such as mechanical manufacturing, building construction, indoor decoration and geometric construction comprises a to-be-guided line jaw and a guide-out line jaw which are located on the same plane and can be relatively rotatably connected. The guide-out line jaw is provided with an edge and in line contact with the plane where a guide-out line is located through the edge. The bottom of the to-be-guided line jaw can form optional tilt angles when being in contact with the plane where a to-be-guide line is located. By the line guide gauge simple in structure, plane building and extending and straight line rotating in the three-dimensional space can be achieved conveniently.

Description

technical field [0001] The invention relates to a tool for establishing and extending a plane and a rotating straight line in a three-dimensional space, in particular to a lead wire gauge, which is suitable for the fields of machine manufacturing, building construction, interior decoration, geometric drawing and the like. Background technique [0002] In three-dimensional space, tools for establishing and extending planes and rotating straight lines in two-dimensional space are often used tools such as height ruler, square, set square, ruler, tape measure, T-square and cotton thread. The method of plane and rotating straight line in three-dimensional space generally adopts gravity hanging line method and two-point connecting line method. In the fields of machinery manufacturing, building construction, interior decoration, and geometry teaching, datum conversion is often used for measurement, marking, etc. At present, there is no effective and accurate conversion method and t...
