Abstract
The utility model discloses a kind of portable drawing survey tool, comprise ruler body, ruler body is formed by connecting by bindiny mechanism by the ruler that at least three length is identical, and the ruler of ruler body end is fixedly installed protractor, and the right-angle side of described protractor is identical with the length of ruler.The utility model novel structure, reasonable in design, protractor and ruler combine, and by multiple ruler by the hinged setting of pressure convex-concave button, be convenient to the independent assortment realized between ruler, increase its using function, effective minimizing and avoid incomplete the caused measurement of instrument inaccurate, low and the ropy problem of drawing efficiency, and this survey tool, take up room after folding little, be convenient to deposit and carry, by arranging groove and the slipmat be arranged in groove and tread plate on protractor and ruler, when being convenient to draw, instrument is stable, improve the precision drawn.
Description
Technical field
The utility model relates to a kind of survey tool, is specifically related to a kind of portable drawing survey tool.
Background technology
In drawing course, usually various drawing instrument can be used, existing Specialty Design drawing survey tool, kind is many, multiple functional, size is also varied, but current drawing survey tool, usually be all separately use separately, such as T-shaped chi, set square, ruler, protractor etc., usually be all separate to be used alone, for the student that academic program designs and draws, usually need to carry multiple drawing instrument simultaneously, because its size dimension is different, therefore carry and inconvenience, especially T-shaped chi, because its length is larger, be unfavorable for carrying with and collecting, multiple types of tools carries together, easily there is the problem of leaking band or losing, inconvenience is brought to user, at present, in drawing survey tool, especially the drawing instrument of student's use, mostly be plastic material make, in use, easily there is the skew of instrument, cause the line segment that draws and measure inaccurate, the drawing drawn out is nonconforming, the time of waste user.
Utility model content
For problems of the prior art, the purpose of this utility model is to design provides a kind of portable drawing survey tool easy to use.
The portable drawing survey tool of described one, comprise ruler body and protractor, it is characterized in that described ruler body is formed by connecting by bindiny mechanism by the ruler that at least three length is identical, the ruler of ruler body end is fixedly installed protractor, and the right-angle side of described protractor is identical with the length of ruler.
The portable drawing survey tool of described one, it is characterized in that described bindiny mechanism comprises pressure convex-concave button, described pressure convex-concave button is arranged on the two ends of ruler, and adjacent ruler link is articulated and connected by pressure convex-concave button.
The portable drawing survey tool of described one, it is characterized in that described protractor being provided with four groove A, the two ends of described ruler are provided with groove B.
The portable drawing survey tool of described one, it is characterized in that being provided with slipmat in described groove A and groove B, in described slipmat, integral type is provided with tread plate.
The portable drawing survey tool of described one, is characterized in that four groove A are trapezoidal setting.
The utility model novel structure, reasonable in design, protractor and ruler combine, and by multiple ruler by the hinged setting of pressure convex-concave button, be convenient to the independent assortment realized between ruler, increase its using function, effective minimizing and avoid incomplete the caused measurement of instrument inaccurate, low and the ropy problem of drawing efficiency, and this survey tool, take up room after folding little, be convenient to deposit and carry, by arranging groove and the slipmat be arranged in groove and tread plate on protractor and ruler, when being convenient to draw, instrument is stable, improve the precision drawn.

Detailed description of the invention
The utility model is further illustrated below in conjunction with Figure of description.
As Figure 1-4, a kind of portable drawing survey tool of the utility model, comprise ruler body 1, ruler body 1 is formed by connecting by bindiny mechanism by the ruler 2 that at least three length is identical, the concrete number of ruler 2, can assemble according to actual conditions, and the ruler 2 of ruler body 1 end is fixedly installed protractor 3, the right-angle side of protractor 3 is identical with the length of ruler, is 25cm.Bindiny mechanism comprises pressure convex-concave button 4, pressure convex-concave button 4 is arranged on the two ends of ruler, adjacent ruler link is articulated and connected by pressure convex-concave button 4, this vibrational power flow can realize the rotation of 360 degree, ruler, can free split between each ruler, is combined into different survey tools, may be combined with into set square, square or independent ruler etc., easy to use, function is multiplex, for Specialty Design drawing measures the requirement solving difference in functionality ruler.
Existing drawing survey tool, mostly be plastic material, in use, often there will be the movement of survey tool, cause the precision of drafting not high, for solving this technical problem, protractor 3 is provided with four groove A5, the two ends of ruler are provided with groove B6, wherein, four groove A5 are trapezoidal setting, this vibrational power flow is convenient left, the use of the right hand, for further fixation measuring instrument, slipmat 7 is provided with in groove A5 and groove B6, in slipmat 7, integral type is provided with tread plate 8, the setting of tread plate 8 and slipmat 7, be convenient to when drafting drawing, drawing tool is fixed, the further precision improving drafting.
