Description

The lattice chis of using more

The utility model relates to the lattice chis of using more.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliance, the big class of office appliance, write or drawing article the assistant product group of writing or draw, other class drawing instrument not to be covered or write or drawing appliance or enclosure group technical field.Be numbered B43L13/00.

At present, existing and once had about other class drawing instrument not to be covered or write or the technology of drawing appliance or annex was all done very fruitful effort to the demand of combined stationery, also once did many outstanding designs and scheme.As being declared by Liu Guangyi of 1993 Decrees of Patent Office of China, Granted publication number is CN2127061Y, and China Patent No. (ZL) is: No. 91217309.2 titles are many utility model patents with bevel protractors, the technical scheme that is adopted.Other class drawing instrument not to be covered write or drawing appliance or attachment technique aspect be a routine of great value invention, it has solved the problem of convertible multiple angles in the ruler application process effectively.But still have some deficits, it also is difficult to solve make set square, protractor and ruler three in the problem of one.

The purpose of this utility model is to provide a kind of lattice chi of using more.Make set square, protractor and ruler three in the problem of one with solution.

The purpose of this utility model is achieved in that this utility model uses the lattice chi more.Mainly constitute by set square, protractor, ruler.Its major part set square, protractor, ruler are made with the hard plastics injection mo(u)lding.Set square is positioned at the left side, and ruler is positioned at the base, carves scale and numeral then and just can use.The three is integrated.So just realized the purpose of this utility model.

The utility model and original other class drawing instrument not to be covered or write or the technology of drawing appliance or annex has been compared an advantage and improvement;

The first, because the utility model has designed in technical scheme set square, protractor and ruler three has been closed on one.Make set square, protractor and ruler three in the problem of one thereby just can more effectively solve.

Accompanying drawing provides the structural representation of the utility model external form:

The numbering of parts explanation in the schematic diagram: (1) set square (2) protractor (3) ruler

Below in conjunction with accompanying drawing, the utility model is described further:

As shown in the figure, the multiplex lattice chi of the utility model. Mainly by set square (1), protractor (2), Ruler (3) consists of. Its major part set square (1), protractor (2), ruler (3) are used The hard plastics injection mo(u)lding is made. Set square (1) is positioned at the left side, and ruler (3) is positioned at the base, Carving then scale and numeral just can use. The three is integrated. So just realized the utility model Purpose. Make set square, protractor and ruler three in the problem of one thereby just can solve.

Below by embodiment, the utility model is done more detailed description:

Embodiment 1, in use, takes measurement of an angle if desired, then uses protractor (2) part of this chi, then uses ruler (3) part, set square (1) part can draw 30 degree and 60 angles of spending when needing the long lines of picture.Thereby just can realize the purpose of this utility model.

Realize that preferred plan of the present utility model is is material with the rigid plastics, utilize the basic equipment of injection moulding factory, take to produce by batch in a large number, the demand with supply educational circles so just can realize practical value of the present utility model and economic worth better.

Claims

1. use the lattice chi one kind, it is to be made of set square (1), protractor (2), ruler (3) more.It is characterized in that the ruler (3) that set square (1) base and protractor (2) base are formed.
