Abstract
The utility model relates to a novel combination ruler, which belongs to the technical field of the group of straight rulers of the subclass of writing or drawing supplies; writing or drawing auxiliary supplies of the class of writing or drawing tools; office supplies under the subsection of printing in the section of performing operations and transporting according to the International Patent Classification (IPC). The number is B437/00. The utility model is composed of a triangular ruler with an angle of 60 DEG, a protractor, an equilateral triangular ruler, an installing plate and a straight ruler. The utility model is characterized in that the semicircle-shaped protractor of the utility model is installed on the flat plate-shaped straight ruler. The utility model is a novel combination ruler with practical value.
Description
The utility model relates to a kind of novel combination ruler.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing instrument, and the big class of office appliance is write or drawing article, the assistant product group of writing or draw, ruler technical group field.Be numbered B437/00.
At present, the technology about ruler existing and that once had was all done very fruitful effort to the demand of novel combination ruler, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Gu Zhengwu, Granted publication number is CN2243393Y, China Patent No. (ZL) is: No. 95218283.1 utility model title is the utility model patent of " convenient multi-purpose teaching drawing ruler ", the technical scheme that is adopted.At the ruler technical elements is a routine of great value invention, and it has solved the problem of teaching drawing ruler convenient multi-purpose effectively.But still have some deficits, its also be difficult to solve finishes angle and draws, takes measurement of an angle, draws the arm of angle on a chi, and draws miter angle easily and 60 degree, 30 are spent angles to reach the problem that a chi is used more.
The purpose of this utility model is to provide a kind of novel combination ruler.On a chi, finish angle and draws, take measurement of an angle, draw the arm of angle to solve, and to draw miter angle easily and 60 degree, 30 are spent angles to reach the problem that a chi is used more.
The purpose of this utility model is achieved in that a kind of novel combination ruler of utility model.Mainly constitute by 60 degree set squares, protractor, equilateral triangle chi, installing plate, ruler.The installing plate of its protruding writing board shape adopts the ruler of injection molding method and writing board shape to be processed into one, forms ruler, the protractor mounting structure of a protruding writing board shape.The protractor of its semicircular in shape adopts adhesive method to be installed on the ruler of writing board shape.Form the angle measurement and the angle rendering architecture of a semi-circular shape.The equilateral triangle chi of its writing board shape adopts adhesive method to be installed on the ruler of writing board shape.The right-angle side that forms an equiangular triangle shape is drawn and 45 degree rendering architectures.60 degree set squares of its writing board shape adopt adhesive method to be installed on the ruler of writing board shape.Form 60 triangular shaped degree, 30 degree rendering architectures.Its installing plate acts on ruler by injection molding method.Thereby make installing plate satisfy the requirement that set square and protractor are installed.Its 60 degree set squares, equilateral triangle chi, protractor act on ruler by adhesive method.Thereby make it finish the drafting angle that takes measurement of an angle, measure the task of length or the like.So just realized the purpose of this utility model.
The technology of the utility model and original ruler has been compared three advantages and improvement;
The first, because the utility model has designed protractor in technical scheme, so solved the problem that is used for measuring or drawing angle;
The second, because the utility model has designed the equilateral triangle chi in technical scheme, so solved the problem that is conveniently used for picture reference axis or right angle and miter angle;
The 3rd, because the utility model designed installing plate in technical scheme, so solved protractor and set square can be installed firm problem on the right angle.Thereby just can more effectively solve and on a chi, finish angle and draw, take measurement of an angle, draw the arm of angle, and draw miter angle and 60 degree, 30 degree angles easily more to reach the problem that a chi is used.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the overall installation structural representation of a kind of novel combination ruler of the utility model;
Fig. 2 is the ruler member profile structural representation of a kind of novel combination ruler of the utility model;
The numbering of parts explanation in the schematic diagram:
160 degree set squares, 2 protractors, 3 equilateral triangle chis, 4 installing plates, 5 rulers
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, a kind of novel combination ruler of the utility model.Mainly constitute by 60 degree set squares 1, protractor 2, equilateral triangle chi 3, installing plate 4, ruler 6.The installing plate 4 of its protruding writing board shape adopts the ruler 5 of injection molding method and writing board shape to be processed into one, forms ruler, the protractor mounting structure of a protruding writing board shape.The protractor 2 of its semicircular in shape adopts adhesive method to be installed on the ruler 5 of writing board shape.Form the angle measurement and the angle rendering architecture of a semi-circular shape.The equilateral triangle chi 3 of its writing board shape adopts adhesive method to be installed on the ruler 5 of writing board shape.The right-angle side that forms an equiangular triangle shape is drawn and 45 degree rendering architectures.60 degree set squares 1 of its writing board shape adopt adhesive method to be installed on the ruler 5 of writing board shape.Form 60 triangular shaped degree, 30 degree rendering architectures.Its installing plate 4 acts on ruler 5 by injection molding method.Thereby make installing plate 4 satisfy the requirement that triangle angle square and protractor 2 are installed.Its 60 degree set squares 1, equilateral triangle chi 3, protractor 2 act on ruler 5 by adhesive method.Thereby make it finish the drafting angle that takes measurement of an angle, taking measurement of an angle etc. of task.So just realized the purpose of this utility model.Thereby just can solve and on a chi, finish angle and draw, take measurement of an angle, draw the arm of angle, and draw miter angle and 60 degree, 30 degree angles easily more to reach the problem that a chi is used.
Below by embodiment, the utility model is done more detailed description:
Embodiment 1, in force, if draw the length of straight line or measurement straightway.Can use ruler 6 to finish.If want to finish the angular surveying or the drafting of common angle, can adopt the protractor 2 on the ruler 6 to achieve the goal.
Embodiment 2, and in force, if draw right-angle side and straight coordinate system, equilateral triangle chi 3 can meet the demands easily.And want with the method for most convenient draw special I---miter angle and 60 degree angles can be finished by equilateral triangle chi 3 and 60 degree angle squares respectively.Thereby just can realize the purpose of this utility model.
Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of stationery production plant, take injection molded to produce by batch, the demand with supply educational circles so just can realize practical value of the present utility model and economic worth better.
