Description

Multifunctional ruler
The utility model relates to multifunctional ruler.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliance, and the big class of office appliance is write or drawing appliance, the assistant product group of writing or draw, the angle square in the ruler and the ruler technical group field that can pivot.Be numbered B43L 7/12.
At present, existing and once had about ruler in angle square and the ruler technology that can pivot the demand of multifunctional ruler was all done very fruitful effort, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Zhang Baoan, Granted publication number is CN2220369Y, China Patent No. (ZL) is: No. 95207903.8 utility model title is the utility model patent of " student write standard chi ", the technical scheme that is adopted.Angle square in ruler and the ruler technical elements that can pivot are routine of great value inventions, and it has solved the problem that can allow student's standard write effectively.But still have some deficits, it also is difficult to solution can be used in combination multiple student with chi problem.
The purpose of this utility model is to provide a kind of multifunctional ruler.To solve the problem that multiple student can be used in combination with chi.
The purpose of this utility model is achieved in that this utility model multifunctional ruler.Mainly constitute by protractor, connecting pin, set square, ruler.Its major part connecting pin is by selecting for use in the city.The hard plastic injection molding processing and manufacturing of protractor, set square, ruler.At first, process protractor, set square and ruler with rigid plastics, in the intersection of protractor, set square and ruler connecting pin is installed then, connecting pin can connect as one protractor, set square and ruler.So just realized the purpose of this utility model.
The utility model has been compared an advantage and improvement with the angle square in the original ruler with the ruler technology that can pivot;
The first, because the utility model has designed connecting pin in technical scheme, protractor, set square, ruler can be connected as one.Thereby just can more effectively solve the problem that multiple student can be used in combination with chi.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the main TV structure schematic diagram of the utility model multifunctional ruler;
The numbering of parts explanation in the schematic diagram: (1) protractor (2) connecting pin (3) set square (4) ruler
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, the utility model multifunctional ruler. Mainly by protractor (1), connect pin (2), Set square (3), ruler (4) consist of. Its main part connects pin (2) by selecting in the city. Protractor (1), set square (3), ruler (4) are used the hard plastic injection molding processing and manufacturing. At first, Process protractor (1), set square (3) and ruler (4) with rigid plastics, then in angulation Device (1), set square (2) are connected 4 with ruler) intersection install to connect pin (2), connect pin ( 2) protractor (1), set square (2) and ruler (4) can be connected as one. So just Realized the purpose of this utility model. Multiple student can be combined in one with chi thereby just can solve Work the problem of using.
Below by embodiment, the utility model is done more detailed description:
Embodiment 1, in use, can remove to use different chi (protractor (1), set square (3) and ruler (4)) according to user's requirement.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 stationery production plant, take level assembling in batch to produce by batch, the demand with supply student circle so just can realize practical value of the present utility model and economic worth better.
