Abstract
The utility model discloses a special flexible rule for garden, belonging to a rule, wherein the upper side of one surface of the rule is provided with length scale marks, and the lower side thereof is provided with diameter scale marks which are calculated corresponding to the length scale marks, and the other surface of the rule is provided with cross section area scale marks which are calculated corresponding to the length scale marks. Compared with the prior art, the special flexible rule for garden can directly read the diameter scale and the cross section area scale of a measured tree from the rule, which improves the working efficiency of garden workers, and has the characteristics of reasonable design, simple structure, easy processing, convenient use and the like.
Description
Technical field
The utility model relates to a kind of ruler, the special-purpose tape in specifically a kind of gardens.
Background technology
The gardens staff wants diameter and the cross-sectional area of every trees in the frequent survey record gardens, diameter and the cross-sectional area of measuring trees at present all are to use common tape, measure the girth of trees earlier, then according to formula: girth=π * diameter calculates the tree diameters value; Again according to formula: cross-sectional area=π * radius
2, calculate the cross-sectional areas of trees.Use very not aspect.
The utility model content
Technical assignment of the present utility model is at above weak point, and a kind of simple in structure, the diameter that is easy to process, can directly measure trees and the special-purpose tape in a kind of gardens of cross-sectional area are provided.
The technical scheme that its technical matters that solves the utility model adopts is: on the one side of ruler, upside is provided with the length scale mark, and downside is provided with the diameter scale mark that corresponding length scale mark calculates; The another side of ruler is provided with the cross-sectional area scale mark that corresponding length scale mark calculates.
The scale of diameter scale mark is that the scale according to corresponding length scale mark utilizes formula: girth=π * diameter calculates, and the scale of cross-sectional area scale mark is that the scale according to corresponding diameter scale mark utilizes formula: cross-sectional area=π * radius
2Calculate.
The special-purpose tape in a kind of gardens of the present utility model is compared with prior art, can directly on ruler, read diameter scale and the cross-sectional area scale of measuring trees, thereby improved gardens staff's work efficiency, have reasonable in design, simple in structure, be easy to processing, characteristics such as easy to use, thereby, have good value for applications.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing 1 is the synoptic diagram of the special-purpose tape in a kind of gardens;
Accompanying drawing 2 is the rear view of accompanying drawing 1.
Among the figure: 1, ruler, 2, the length scale mark, 3, the diameter scale mark, 4, the cross-sectional area scale mark.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The special-purpose tape in a kind of gardens of the present utility model, on the one side of ruler 1, upside is provided with length scale mark 2, and downside is provided with the diameter scale mark 3 that corresponding length scale mark 2 calculates; The another side of ruler is provided with the cross-sectional area scale mark 3 that corresponding length scale mark 2 calculates.
Special-purpose its processing and fabricating of tape in a kind of gardens of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
