Description

Novel set square

(1) field under

The utility model relates to novel set square.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) division, printing branch is write or drawing appliance, and the big class of office appliance is write or the drawing article group, big group of ruler, angle square and the little technical group field of the ruler that can pivot.Classification number is B43L7/12.

(2) background technology:

At present, the technology about the angle square and the ruler that can pivot existing and that once had was all done very fruitful effort to the demand of novel set square, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Zhang Zhen, Granted publication number is CN2224737Y, China Patent No. (ZL) is: No. 95230665.4 utility model title is the utility model patent of " the anti-multifunctional drawing ruler of smearing ", the technical scheme that is adopted.Is a routine of great value invention at angle square with the ruler technical elements that can pivot, and it has solved the anti-daubing problem of multifunctional drawing ruler effectively.But still have some deficits, it is not portable that it also is difficult to solve the traditional triangle plate, the problem that fractures easily.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of novel set square.Not portable to solve the traditional triangle plate, the problem that fractures easily.

The purpose of this utility model is achieved in that the novel set square of this utility model.Mainly constitute by ruler I, ruler II, ruler III, rotating shaft I, rotating shaft II, locating slot.Its ruler I, ruler II, ruler III are rectangular shape, use plastic material, through the injection moulding processing and manufacturing.Its rotating shaft I, rotating shaft II are cylindrical shapes, use plastic material, through the injection moulding processing and manufacturing.Its locating slot is a semi-circular shape, through the cutting processing manufacturing.Rotating shaft I adopts rubbing method to be connected the left position of ruler II, constitutes round-shaped pivot structure, and function is to play rotating action.Rotating shaft II adopts rubbing method to be connected the right end position of ruler II, constitutes round-shaped pivot structure, and function is to play rotating action.Ruler I adopts adhering method to be installed in the upper end position of rotating shaft I, constitutes convex shape, and function is to play the role of positioning.Ruler III adopts adhering method to be installed in the upper end position of rotating shaft II, constitutes convex shape, and function is to play the role of positioning.Locating slot adopts cutting method to be installed in the left position of ruler I, constitutes the outer recessed structure of semi-circular shape, and function is to play the role of positioning.So just realized the purpose of this utility model.

The advantage of utility model: the utility model has been compared three advantages and improvement with original angle square with the ruler technology that can pivot;

The first, because the utility model has designed the ruler of collapsible set square in technical scheme, so convenient the use is easy to carry;

The second, because the utility model has designed rotating shaft in technical scheme, so rotatable;

The 3rd, because the utility model has designed locating slot in technical scheme, so can locate; Thereby it is not portable just more effectively to have solved the traditional triangle plate, the problem that fractures easily.

(4) description of drawings:

Accompanying drawing provides structural representation of the present utility model:

Fig. 1 is the main TV structure schematic diagram of novel set square of the present utility model;

Fig. 2 is the mounting structure schematic diagram of novel set square of the present utility model;

The numbering of parts explanation in the schematic diagram: 1 ruler I, 2 ruler II, 3 ruler III, 4 rotating shaft I, 5 rotating shaft II, 6 locating slots

(5) specific embodiment:

In the optimum implementation of novel set square of the present utility model, its technical scheme is achieved in that and below in conjunction with accompanying drawing the utility model is described further:

Its static structure: see also Fig. 1, as shown in the figure, novel set square of the present utility model.Mainly constitute by ruler I 1, ruler II 2, ruler III 3, rotating shaft I 4, rotating shaft II 5, locating slot 6.Rotating shaft I 4 adopts rubbing method to be connected the left position of ruler II 2, constitutes round-shaped pivot structure, and function is to play rotating action.Rotating shaft II 5 adopts rubbing method to be connected the right end position of ruler II 2, constitutes round-shaped pivot structure, and function is to play rotating action.Ruler I 1 adopts adhering method to be installed in the upper end position of rotating shaft I 4, constitutes convex shape, and function is to play the role of positioning.Ruler III 3 adopts adhering method to be installed in the upper end position of rotating shaft II 5, constitutes convex shape, and function is to play the role of positioning.Locating slot 6 adopts cutting method to be installed in the left position of ruler I1, constitutes the outer recessed structure of semi-circular shape, and function is to play the role of positioning.

Its dynamic structure: in force:

Its ruler I 1 acts on ruler II 2 by rotating shaft I 4, thereby finishes folding task.Its ruler III 3 acts on ruler II 2 by rotating shaft III 5, thereby finishes folding task.So just realized the purpose of this utility model.Thereby it is not portable just to have solved the traditional triangle plate, the problem that fractures easily.

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

The novel set square of this utility model is work like this:

In use, when using, its ruler I 1 acts on ruler II 2 by rotating shaft I 4, thereby finishes folding task.Its ruler III 3 acts on ruler II 2 by rotating shaft II 5, thereby finishes folding task.

In use, when carrying, ruler I 1, ruler III 3 are rotated to horizontal level.

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