Description
Technical field
This utility model relates to a kind of stationery field, more specifically, it relates to a kind of ruler.
Background technology
Ruler is conventional picture and survey tool in our daily life and study.Ruler is generally available picture straight line, and when drawing angle, we can paint by protractor.But some special angles, for instance 30 °, 45 °, 60 °, 90 °, can by set square saving drawing step.
In prior art, generally having 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 us simultaneously need to 30 °, 45° angle time, it is necessary to set square two pieces different, and two pieces of set square volumes are relatively big, tend to loss one piece or can not find between a period of time, at this moment often just relatively awkward, and special angle is not only above-mentioned several, also have 15 °, 135 °.So, how can the volume of less special angle set square, multi-angle can be provided again to select, can as a research direction of design triangle plate in future.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is in that to provide a kind of multi-angle set square, reduces the volume of two pieces of set squares, it is provided that multi-angle picture demand.
For achieving the above object, this utility model provides following technical scheme: a kind of multi-angle set square, including the set square a at isosceles right angle with have 15 °, 30 °, the set square b at 135 ° of three angles, the sidewall of 15 ° of described set square 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 sidewall of described set square a is provided with the containing cavity of storage slide block, the length of slide block is less than the length of dovetail groove, the end of described dovetail groove is provided with limited block.
This utility model is further arranged to: the sidewall of described containing cavity is provided with the spring of connection sliding block.
This utility model is further arranged to: spring and containing cavity diapire are 90 ° of settings.
This utility model is further arranged to: spring and containing cavity diapire are 45 ° of settings.
Compared with prior art, there is advantages below in this utility model multi-angle set square:
1, both set squares original are combined into one piece, reduce volume；
2, the risk that one of which 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. 5, this utility model ruler embodiment is described further.
Embodiment one
As it is shown in figure 1, a kind of multi-angle set square, including the set square a and the set square b with 15 °, 30 °, 135 ° three angles at isosceles right angle, the length of the common oblique side of 15 ° of set square b and 135 ° is equal with the length of the hypotenuse of set square a.Being provided through dovetail groove on the sidewall of common oblique side, the one end of dovetail groove is provided with limited block.Being provided with the slide block coordinating dovetail groove on the sidewall of the hypotenuse of set square a, the length of slide block, less than the length of dovetail groove, sidewall is additionally provided with the containing cavity of storage slide block, and the axial both ends of containing cavity are closed by elastomeric objects.
This example structure is simple, easy to operate.Limited block can anti-limited slip block excessive slip, it is possible to play positioning action, it is prevented that dislocation after set square a and set square b splicing.
Embodiment two
If Fig. 2 is to shown in 5, a kind of multi-angle set square, including the set square a and the set square b with 15 °, 30 °, 135 ° three angles at isosceles right angle, the length of the common oblique side of 15 ° of set square b and 135 ° is equal with the length of the hypotenuse of set square a.The sidewall of common oblique side is provided through dovetail groove, the sidewall of the hypotenuse of set square a is provided with the slide block coordinating dovetail groove.Being additionally provided with the containing cavity of storage slide block on the porch side walls of set square a, the diapire of containing cavity is provided with the spring of connection sliding block.
Preferably, the quantity of spring is some, connects better effects if, and when making set square a and set square b splicing, structural strength is higher, more firmly.
Spring and containing cavity diapire are 90 ° of settings, and set square a is higher with the spliced structural strength of set square b.
Spring and containing cavity diapire are 45 ° of settings, and set square a is with set square b splicing, and 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, it is possible to play positioning action, it is prevented that dislocation after set square a and set square b splicing.
Slide block all can be taken in containing cavity by embodiment one and embodiment two, can prevent when being used alone set square a, the use affecting hypotenuse of slide block.Embodiment two is more convenient compared with embodiment one, embodiment one needs to rely on gravity to make slide block naturally take off in containing cavity, and slide block is drawn in containing cavity by the pulling force of the spring that second embodiment can rely on automatically, and embodiment two 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 preferred implementation of the present utility model, and for the person of ordinary skill of the art without departing under the premise of this utility model principle, it is also possible to make some modification and improvement, these also should be regarded as protection domain of the present utility model.
