Description
Technical field
The present invention relates to a kind of stationery field, more particularly, it relates to a kind of ruler.
Background technology
Ruler is conventional picture and survey tool in our daily life and study.Ruler generally can be used to picture straight line, and when drawing angle, we can paint by protractor.But some special angles, such as 30 °, 45 °, 60 °, 90 °, can by set square saving drawing step.
In prior art, generally have two kinds of set squares, one is isosceles right angle triangles, and a kind of is the right angle triangle at 30 ° of angles.Therefore, when we need simultaneously 30 °, 45° angle time, just need the set square that two pieces different, and two pieces of set square volumes are larger, often easily lose between one piece or a period of time and can not find, at this moment often just more awkward, and special angle is not only above-mentioned several, also has 15 °, 135 °.So, how can the volume of less special angle set square, multi-angle can be provided again to select, can be used as a research direction of design triangle plate in the future.
Summary of the invention
For the deficiency that prior art exists, the object of the present invention is to provide a kind of multi-angle set square, reduce the volume of two pieces of set squares, multi-angle picture demand is provided.
For achieving the above object, the invention provides following technical scheme: a kind of multi-angle set square, comprise the set square a at isosceles right angle and there is the set square b at 15 °, 30 °, 135 ° three angles, the sidewall of described 15 ° of triangle ruler b and the common oblique side of 135 ° is provided with dovetail groove, the length of described common oblique side is equal with the length of the hypotenuse of set square a, the sidewall of the hypotenuse of described set square a is provided with the slide block coordinating dovetail groove.
The present invention is set to further: the length of slide block equals the length of dovetail groove.
The present invention is set to further: the length of slide block is less than the length of dovetail groove, and the end of described dovetail groove is provided with limited block.
The present invention is set to further: the sidewall of set square a is provided with the accommodating cavity of storage slide block.
The present invention is set to further: the sidewall of accommodating cavity is provided with the spring of connection sliding block.
The present invention is set to further: spring and accommodating cavity diapire are 90 ° and arrange.
The present invention is set to further: spring and accommodating cavity diapire are 45 ° and arrange.
Compared with prior art, there is following advantage in multi-angle set square of the present invention:
1, both set squares original are combined into one piece, reduce volume;
2, the risk that wherein a kind of set square is lost is avoided;
3, the picture demand of 15 °, 30 °, 45 °, 60 °, 90 °, 135 ° multi-angles is provided.

Detailed description of the invention
Referring to figs. 1 through Fig. 7, ruler embodiment of the present invention is described further.
Embodiment one
As shown in Figure 1, a kind of multi-angle set square, comprise the set square a at isosceles right angle and there is the set square b at 15 °, 30 °, 135 ° three angles, the length of 15 ° of triangle ruler b and the common oblique side of 135 ° is equal with the length of the hypotenuse of set square a, the sidewall of common oblique side is provided with dovetail groove, the sidewall of the hypotenuse of set square a is provided with the slide block coordinating dovetail groove.
Embodiment two
As shown in Figure 2, a kind of multi-angle set square, comprises the set square a at isosceles right angle and have the set square b at 15 °, 30 °, 135 ° three angles, and the length of 15 ° of triangle ruler b and the common oblique side of 135 ° is equal with the length of the hypotenuse of set square a.The sidewall of common oblique side is provided with dovetail groove, and dovetail groove length equals the half of common oblique side length, and the sidewall setting of set square a is run through in one end of dovetail groove.The sidewall of the hypotenuse of set square a is provided with the slide block coordinating dovetail groove, the length of slide block is equal with dovetail groove length.
This example structure is simple, easy to operate.The dovetail groove of half is arranged can anti-limited slip block excessive slip, can play positioning action, prevent set square a and set square b from splicing and misplace (effect namely playing limited block) afterwards.
Embodiment three
As shown in Figure 3, a kind of multi-angle set square, comprises the set square a at isosceles right angle and have the set square b at 15 °, 30 °, 135 ° three angles, and the length of 15 ° of triangle ruler b and the common oblique side of 135 ° is equal with the length of the hypotenuse of set square a.The sidewall of common oblique side runs through and is provided with dovetail groove, an end of dovetail groove is provided with limited block.The sidewall of the hypotenuse of set square a is provided with the slide block coordinating dovetail groove, sidewall is also provided with the accommodating cavity of storage slide block, the axial both ends of accommodating cavity are closed by elastomeric objects.
Embodiment four
As shown in Fig. 4 to 7, a kind of multi-angle set square, comprises the set square a at isosceles right angle and have the set square b at 15 °, 30 °, 135 ° three angles, and the length of 15 ° of triangle ruler b and the common oblique side of 135 ° is equal with the length of the hypotenuse of set square a.The sidewall of common oblique side runs through and is provided with dovetail groove, the sidewall of the hypotenuse of set square a is provided with the slide block coordinating dovetail groove.The porch side walls of set square a is also provided with the accommodating cavity of storage slide block, the diapire of accommodating cavity is provided with the spring of connection sliding block.
Preferably, the quantity of spring is some, and connect better effects if, when set square a and set square b is spliced, structural strength is higher, more firmly.
Spring and accommodating cavity diapire are 90 ° and arrange, set square a and the spliced structural strength of set square b higher.
Spring and accommodating cavity diapire are 45 ° and arrange, and in set square a and set square b splicing, spring stress is little, can extend the service life of spring.
Preferably, dovetail groove is provided with limited block, can anti-limited slip block excessive slip, can play positioning action, misplaces after preventing set square a and set square b from splicing.
Slide block all can be taken in accommodating cavity by embodiment three and embodiment four, can prevent when being used alone set square a, the use affecting hypotenuse of slide block.Embodiment four is more convenient compared with embodiment three, embodiment three needs to rely on gravity that slide block is taken off in accommodating cavity naturally, and slide block is drawn in accommodating cavity by the pulling force of the spring that embodiment four fundamental rules can rely on automatically, and embodiment four is after set square a and set square b realizes splicing, pulling force exists always, after this too increases splicing to a certain extent, an overall structural strength.
The above makes the preferred embodiment of the present invention, and under not departing from the prerequisite of the principle of the invention for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection scope of the present invention.
