An object of the utility model is to provide a multi -angle set -square has reduced the volume of two set -squares, provides the multi -angle demand of drawing.

Description

A kind of multi-angle set square

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, such as 30 °, 45 °, 60 °, 90 °, can be by set square saving drawing step.

In prior art, typically 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 two pieces of different set squares, and two pieces of set square volumes are relatively big, tend to lose one piece or for the moment between can not find, the most awkward, and the most above-mentioned several of special angle, also 15 °, 135 °.So, how multi-angle can be provided again to select with the volume of less special angle set square, can be as a research direction of design triangle plate in future.

Utility model content

The deficiency existed for prior art, the purpose of this utility model is 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, it is provided with dovetail groove on the sidewall of 15 ° of described set square b and the common oblique side of 135 °, the length of described common oblique side is equal with the length of the hypotenuse of set square a, the slide block coordinating dovetail groove it is provided with on the sidewall of the hypotenuse of described set square a, 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, the sidewall of 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. avoid the risk that one of which set square is lost；

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. 4, this utility model ruler embodiment is described further.

As shown in Figures 1 to 4, a kind of multi-angle set square, including the set square a at isosceles right angle with have the set square b at 15 °, 30 °, 135 ° three angles, 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.It is provided through dovetail groove on the sidewall of common oblique side, 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 effect more preferable, and when making set square a and set square b splice, structural strength is higher, more firmly.

Spring and containing cavity diapire are 90 ° of settings, and set square a structural strength spliced with set square b is higher.

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, positioning action can be played, prevent set square a and set square b from misplacing after splicing.

Slide block is drawn in containing cavity by the pulling force of the spring that multi-angle set square of the present utility model can rely on automatically, can prevent when being used alone set square a, the use affecting hypotenuse of slide block.

The above makes preferred implementation of the present utility model, for the person of ordinary skill of the art without departing from this utility model principle on the premise of, it is also possible to making some modification and improvement, these also should be regarded as protection domain of the present utility model.
