Abstract
The utility model relates to a novel backing plate for a protractor, which belongs to the technical field of the group of writing or drawing plates which can be repeatedly used or small flat plates of the subclass of writing or drawing supplies; writing or drawing auxiliary supplies of the class of writing or drawing appliances; 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 B43L1/00. The utility model is composed of a circle drawing groove, a protractor, a backing plate body, a ruler, a positioning circular hole and an additional plate. The utility model is characterized in that the semicircle-shaped protractor of the novel backing plate for a protractor is processed into a whole with the flat plate-shaped additional plate. The utility model is a novel backing plate for a protractor with practical value.
Description
The utility model relates to the novel angle gauge backing plate.(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 article, the assistant product group of writing or draw, reusable plate of writing or drawing or tablet technical group field.Be numbered B43L 1/00.
At present, the technology about reusable plate of writing or drawing or tablet existing and that once had was all done very fruitful effort to the demand of novel angle gauge backing plate, also once designed many outstanding technical schemes.As being declared by Zhang Zhiqun of the Decree of Patent Office of China in 1996, Granted publication number is CN2242794Y, and China Patent No. (ZL) is: No. 922395349 utility model title is the utility model patent of " keeping record of events of teaching blank ", the technical scheme that is adopted.At reusable plate of writing or drawing or tablet technical elements is a routine of great value invention, and it has solved the problem of keeping record of events of teaching blank effectively.But still have some deficits, its also very difficult solution with a backing plate is finished measurement, draws angle and is worked as the problem of lattice chi use to realize that multiple function is used.
The purpose of this utility model is to provide a kind of novel angle gauge backing plate.Finish measurement, draw angle and work as the problem of lattice chi use to solve to realize that multiple function is used with a backing plate.
The purpose of this utility model is achieved in that the novel angle gauge backing plate of this utility model.Mainly constitute by picture circular groove, protractor, backing plate body, lattice chi, positioning round orifice, add-in card.Its major part backing plate body is the thin flat plate shape, makes material with transparent plastic, through the injection molded processing and manufacturing.Its protractor is a semi-circular shape, makes material with transparent plastic, manufactures one through injection molded and backing plate.Its picture circular groove is the half slot shape, through the cutting method processing and manufacturing.The add-in card of its writing board shape adopts the backing plate body of injection molding method and writing board shape to be processed into one.Form the backing structure of a writing board shape.The protractor of its semi-circular shape adopts the add-in card of injection molding method and writing board shape to be processed into one.Structure is drawn and measured to the angle that forms a semi-circular shape.The picture circular groove of its half slot shape adopts cutting method to process on the add-in card of writing board shape.Form the drawing structure of a half slot shape.The lattice chi of its writing board shape adopts the backing plate body of injection molding method and writing board shape to be processed into one.Form the linear measure longimetry structure of a writing board shape.Its positioning round orifice acts on add-in card by hole-punching method.Thereby the requirement of centering when making it satisfy the picture hole.Its protractor acts on add-in card by injection molding method.Thereby make it finish measuring and drawing angle of task.So just realized the purpose of this utility model.
The utility model has been compared three advantages and improvement with original reusable plate of writing or drawing or tablet technology;
The first, because the utility model has designed protractor in technical scheme, so solved the problem that can measure, draw angle;
The second because the utility model designed the picture circular groove in technical scheme, so solved can the draw circles figure problem;
The 3rd, because the utility model has designed the lattice chi in technical scheme, so solved the problem that can measure length.Finish measurement, draw angle and work as the problem of lattice chi use thereby just can more effectively solve to realize that multiple function is used with a backing plate.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the overall appearance structural representation of novel angle gauge backing plate of the present utility model;
The numbering of parts explanation in the schematic diagram: 1 draws circular groove 2 protractors 3 backing plate bodies 4 lattice chis 5 positioning round orifice 6 add-in cards
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, novel angle gauge backing plate of the present utility model.Mainly constitute by picture circular groove 1, protractor 2, backing plate body 3, lattice chi 4, positioning round orifice 5, add-in card 6.Its major part backing plate body 3 is thin flat plate shapes, makes material with transparent plastic, through the injection molded processing and manufacturing.Its protractor 2 is semi-circular shapes, makes material with transparent plastic, manufactures one through injection molded and backing plate.Its picture circular groove 1 is the half slot shape, through the cutting method processing and manufacturing.The add-in card 6 of its writing board shape adopts the backing plate body 3 of injection molding method and writing board shape to be processed into one.Form the backing structure of a writing board shape.The protractor 2 of its semi-circular shape adopts the add-in card 6 of injection molding method and writing board shape to be processed into one.Structure is drawn and measured to the angle that forms a semi-circular shape.The picture circular groove 1 of its half slot shape adopts cutting method to process on the add-in card 6 of writing board shape.Form the drawing structure of a half slot shape.The lattice chi 4 of its writing board shape adopts the backing plate body 3 of injection molding method and writing board shape to be processed into one.Form the linear measure longimetry structure of a writing board shape.Its positioning round orifice 5 acts on add-in card 6 by hole-punching method.Thereby the requirement of centering when making it satisfy the picture hole.Its protractor 2 acts on add-in card 6 by injection moulding shape method.Thereby make it finish measuring and drawing angle of task.So just realized the purpose of this utility model.Finish measurement, draw angle and work as the problem of lattice chi use thereby just can solve to realize that multiple function is used with a backing plate.
Below by embodiment, the utility model is done more detailed description:
Embodiment 1, in force, if it during as common backing plate, only needs be placed on its backing plate body 3 above the page or on the page and writes, and (18 * 26cm) and 16 open the sizableness of page to its area.And, also can be used as bookmark and use because it is transparent thin flat plate.
Embodiment 2, in force, if when thinking the setting-out section or measuring length, can use lattice chi 4 to finish, if will measure or when drawing angle, available quantity hornwork 2 achieves the goal.If will draw bowlder, with the backing plate location, one-pen is placed on and carries out the picture circle in the picture circular groove 1 available one-pen in addition by positioning round orifice 5.Thereby just can realize the purpose of this utility model.
Realize that preferred plan of the present utility model is is material with the transparent plastic, utilize the basic equipment of stationery production plant, take injection molded, cutting method 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.
