Abstract

The utility model discloses a triangle, which comprises a triangle main body, wherein a point throwing part is arranged at the intersection of two right-angle sides of the triangle main body, an inner circle is arranged in the point throwing part, and the triangle main body relates to the technical field of geological survey drawing tools.

Description

Triangular plate

Technical Field

The utility model belongs to the technical field of geological survey drawing tools, and particularly relates to a triangular plate.

Background

The basic geological investigation work is an important work before mineral resource development; in the actual investigation process, the field hand map needs to be carried with the user, and the geological points in the investigation process fall on the field hand map, and the points are generally hollow circles with the diameter of 2mm.

The current method for throwing the ground points is to firstly measure the ground points on a field hand drawing by using a triangle according to the actual plane rectangular coordinates, and then draw a circle with the diameter of 2mm by using a point compass (method 1); or directly with a circle drawing tool of diameter 2mm (method 2). Both the methods are complicated, the method 1 needs to carry a triangle, a dot compass, ink and the like, and the operation is inconvenient; when the circle drawing tool is used in the method 2, the circle center cannot be completely overlapped with the actual geological point, and drawing errors can be caused.

Disclosure of Invention

The present utility model is directed to a triangle, which solves the above-mentioned problems in the prior art.

The technical scheme adopted by the utility model is as follows:

the triangular plate comprises a triangular plate main body, wherein a point throwing part is arranged at the intersection of two right-angle sides of the triangular plate main body, and an inner circle is arranged in the point throwing part.

Preferably, the two right-angle sides of the triangle main body are provided with scale marks, and the intersection point of the two right-angle sides is the starting point of the scale marks.

Preferably, the intersection point of the two right-angle sides of the triangle main body is the center of the inner circle.

Preferably, the inner diameter is 2mm.

Preferably, the triangle main body and the throwing part adopt an integrated structure.

Preferably, the throwing part adopts a circular ring structure.

In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows:

in the utility model, the zero scale mark of the triangle main body is provided with the point throwing part, and the circle center of the inner circle is overlapped with the zero scale mark, so that the point throwing can be directly carried out after the ground point is measured by the triangle, a plurality of measuring tools are not required to be carried, the point throwing error can be reduced, and the operation is convenient.

Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Example 1:

the embodiment provides a concrete structure of a triangle, as shown in fig. 1, which comprises a triangle main body 1, wherein a point throwing part 3 is arranged at the intersection of two right-angle sides of the triangle main body 1, and an inner circle 4 is arranged in the point throwing part 3.

Furthermore, the two right-angle sides of the triangle main body 1 are provided with the scale marks 2, and the intersection point of the two right-angle sides is the starting point of the scale marks 2.

Further, the intersection point of the two right-angle sides of the triangle main body 1 is the center of the inner circle 4.

Further, the inner circle 4 has a diameter of 2mm.

Furthermore, the triangle main body 1 and the throwing part 3 adopt an integrated structure.

Further, the throwing portion 3 has an annular structure.

The working principle is that referring to fig. 1, a point throwing part 3 is arranged at the zero scale mark of the triangle main body 1, the circle center of the inner circle 4 is overlapped with the zero scale mark, so that the point throwing can be directly carried out after the ground particles are measured by the triangle, various measuring tools are not required to be carried, the error of the point throwing can be reduced, and the operation is convenient.

When the three-dimensional ruler is used, geological points are measured on a field hand image through two right-angle sides of the triangular plate main body 1 and the scale marks 2, at the moment, zero scale marks of the scale marks 2, namely the circle center of the inner circle 4 is on a ground mass point, and circles with the diameters of 2mm are directly drawn along the inner circle.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
