Description
Technical field:
The utility model relates to a kind of field plotting board, specifically a kind of field operations mapping Multifunctional three-square ruler.
Background technology:
Three-square rule is the triangular structure with three working faces, is the important tool of measurement, conversion drawing ratio scale, of many uses in daily work and study.But when carrying out surveying work in the wild, there is following problem in existing three-square rule:
(1) when carrying out field measurement, the sight line of three-square rule is too low, not easily aims at the mark a little.
(2) when adding the aids such as straight line, student is difficult to gain the essentials at short notice, often occurs that straight line vertically can not wait phenomenon with ground, produces larger human error.
(3) sight line of three-square rule and line are at not homonymy, and the error between this cannot be eliminated.
Utility model content:
Technical problem to be solved in the utility model is the defect overcoming prior art, provides a kind of field operations mapping Multifunctional three-square ruler being more conducive to field work.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
A kind of field operations mapping Multifunctional three-square ruler, main body is set square, it is characterized in that:
Described set square is isosceles right triangle, and right-angle plane width is 4cm, described set square is provided with sight line and plate rule, and sight line and plate are rule and remained on same vertical plane, improve the precision of terrain exercise.
An isosceles right-angle surface of described set square is provided with a groove, and described groove is fillet rectangle, long 30cm, wide 2cm, dark 1cm, and described groove is used for the montant of fixed fold, and the used time does not receive at montant.
The two ends of described groove clinodiagonal are respectively provided with a square groove, for fixed connector and montant.
The long 28cm of described montant, be divided into bar handle and shaft, described bar handle is connected with set square by connector, on bar handle, plane is provided with a cannelure, cannelure is built with a movable draw ring, and be convenient to montant to pull out in groove, bar handle lower plane is provided with a circular groove, be provided with two inclines in circular groove, prolong circular groove diameter symmetry.
Described connector is cylindrical, lower plane is provided with a boss, boss be square, size and square groove in the same size, compact siro spinning technology connector and groove, connector curved surface upper end is provided with two slide rails and two chutes, slide rail is rectangle, symmetric design, and chute ringwise, vertical with slide rail, two chutes do not communicate.
The utility model is convenient to operation, sight line and plate being rule is arranged on same vertical plane, customer service sight line and plate rule not in the error that same plane causes, make measurement result more accurate, the used time does not fold to pack up and is placed in groove, person easy to use takes care of and carries, and is more conducive to field work.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model set square groove part schematic diagram;
Fig. 3 is floor map on the utility model bar shank portion;
Fig. 4 is the utility model bar shank portion lower plane schematic diagram;
Fig. 5 is the utility model connector schematic diagram;
Wherein: 1-set square; 2-groove; 3-montant; 4-shaft; 5-bar handle; 6-square groove; 7-cannelure; 8-draw ring; 9-circular groove; 10-incline; 11-connector; 12-boss; 13-slide rail; 14-chute.
Detailed description of the invention:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, a kind of field operations mapping Multifunctional three-square ruler, main body is set square 1, set square 1 is isosceles right triangle, right-angle plane width is 4cm, set square 1 is provided with sight line and plate rule, sight line and plate are rule and are remained on same vertical plane, an isosceles right-angle surface of set square is provided with a groove 2, groove 2 is fillet rectangle, long 30cm, wide 2cm, dark 1cm, for the montant 3 of fixed fold and the used time does not receive at montant 3, a square groove 6 is respectively provided with at the two ends of groove 2 clinodiagonal, for fixed connector 11 and montant 3, the long 28cm of montant 3, be divided into bar handle 5 and shaft 6, bar handle 5 is connected with set square 1 by connector 11, on bar handle 5, plane is provided with a cannelure 7, cannelure 7 is built with a movable draw ring 8, be convenient to montant 3 from pull-out in groove 2, bar handle 5 lower plane is provided with a circular groove 9, two inclines 10 are provided with in circular groove 9, prolong circular groove 9 diameter symmetry, for connecting the connector 11 of set square 1 and montant 3 for cylindrical, lower plane is provided with a boss 12, boss 12 is square, size and square groove 6 in the same size, compact siro spinning technology connector 11 and groove 2, connector 11 curved surface upper end is provided with two slide rails 13 and two chutes 14, slide rail 13 is rectangle, symmetric design, chute 14 ringwise, vertical with slide rail, two chutes 14 do not communicate.
