Abstract
The utility model discloses a ruler for leaning geographical knowledge, comprising two protractors, an aiming device storage box, a lower secondary ruler, aiming device fixing holes, an upper secondary ruler and a ruler body, wherein the ruler body is the main part of the ruler for leaning geographical knowledge and integrally takes the shape of a rectangular strip; measuring scale lines are arranged on one long edge of two long edges of the ruler body; at the side with the measuring scale lines, the two protractor are respectively arranged at two ends of the ruler body; the aiming device storage box is arranged at one end of the long edge without the measuring scale lines; at one side close to the long edge with the measuring scale lines, the lower secondary ruler which is integrally triangular is arranged and the upper secondary ruler is arranged on the lower secondary ruler; and the aiming device fixing holes are arranged at the upper edges of the lower and upper secondary rulers. The ruler for leaning geographical knowledge is simple in whole structure, convenient for operation and use, good in stability and high in reliability. By adopting the form one ruler with a plurality of purposes, the technical demands in the aspects of horizontal measurement, gradient measurement, angle measurement, height measurement and sketch drawing can be solved.
Description
Technical field:
The utility model relates to geosophy and commonly uses servicing unit, relates in particular to geosophy and commonly uses the chi tool.
Background technology:
In geographical geology industry, existing measurement device comprises spirit level, theodolite or the like, all is the more expensive equipment of some precisions and price, has only the Mapping departments of specialty just might to dispose and use.Up to the present still can not purchase such equipment in the school instruction and use,, also just can not cultivate student's actual operational capacity so the student also just can't learn corresponding knowledge intuitively as the teaching aid of teaching, with quality-oriented education require incompatible.
The utility model content:
The purpose of this utility model is, overcome the deficiencies in the prior art part, provide a kind of geosophy to commonly use the chi tool, the form that can adopt a chi to use solves horizontal survey, slope measuring, angular surveying, the Technology Need of measurement and sketch drafting aspect highly more.
Geosophy described in the utility model is commonly used the chi tool, includes protractor, sight case, following secondary chi, sight fixing hole, goes up secondary chi and chi main body composition.The chi main body is a main component of the present utility model, the integral body strip that is rectangle, and a long limit in two long limits is provided with the tolerance graduation mark, being provided with tolerance graduation mark one side, at the two ends of chi main body, respectively is provided with a protractor.End on the long limit that the tolerance graduation mark is not set is provided with the sight case.Near long limit one side that is provided with the tolerance graduation mark, be provided with whole following secondary chi triangular in shape, be provided with secondary chi above the secondary chi down.The upper edge of following secondary chi and on the upper edge of secondary chi, be provided with the sight fixing hole.
Geosophy described in the utility model is commonly used the chi tool, and overall structure is simple, and is easy for operation, good stability, reliability height.The form that the utility model adopts a chi to use more can solve horizontal survey, slope measuring, angular surveying, highly measure and the Technology Need of sketch drafting aspect.
Description of drawings:
Accompanying drawing 1 is the structural representation that geosophy described in the utility model is commonly used the chi tool.Secondary chi 4-sight fixing hole 5-goes up secondary chi 6-chi main body under the 1-protractor 2-sight case 3-
The specific embodiment:
Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: geosophy described in the utility model is commonly used the chi tool, includes protractor 1, sight case 2, following secondary chi 3, sight fixing hole 4, goes up secondary chi 5 and chi main body 6 compositions.Chi main body 6 is main components of the present utility model, the integral body strip that is rectangle, and a long limit in two long limits is provided with the tolerance graduation mark, being provided with tolerance graduation mark one side, at the two ends of chi main body 6, respectively is provided with a protractor 1.End on the long limit that the tolerance graduation mark is not set is provided with sight case 2.Near long limit one side that is provided with the tolerance graduation mark, be provided with whole following secondary chi 3 triangular in shape, be provided with secondary chi 5 above the secondary chi 3 down.The upper edge of following secondary chi 3 and on the upper edge of secondary chi 5, be provided with sight fixing hole 4.Geosophy described in the utility model is commonly used the chi tool, and overall structure is simple, and is easy for operation, good stability, reliability height.The form that the utility model adopts a chi to use more can solve horizontal survey, slope measuring, angular surveying, highly measure and the Technology Need of sketch drafting aspect.
