Abstract
The invention discloses a set-square accommodation device. The device provided by the invention comprises an accommodation body and the accommodation body is provided with a first concave groove, a second concave groove and a third concave groove; the outline of the first concave groove is adapted to a right-angle set-square and the outline of the second concave groove is adapted to a thin and long set-square; and the outline of the third second concave groove is adapted to an obtuse-angle set-square. The set-square accommodation device provided by the invention is convenient for storing the set-square through arranging concave grooves which are adapted to different sizes of set-squares on the accommodation body; in the process of utilizing the set-square to draw or measure, the set-square can be used at any time and the set-square is put back so as to avoid losing the set-square; in addition, corners of the periphery of the accommodation body are all circular-arc angles so that the skin cannot be scratched in the process of carrying, using or storing.
Description
Technical field
The present invention relates to a kind of stationery, be specifically related to a kind of set square accommodation device.
Background technology
Set square is one of main drawing tool of immunologing mathematics, measuring angle.Every secondary set square is made up of two special right angled triangles: one is the isosceles right angle triangles, and two acute angles of isosceles right angle triangle all are 45 °; Another is the right angle triangle at special angle, is commonly referred to elongated set square, and the acute angle of elongated set square is respectively 30 ° and 60 °.Now, the third set square has appearred again on the market, i.e. obtuse angle set square, and the obtuse angle set square is the set square that comprises an obtuse angle.But, no matter be the standard set square, the still nearest obtuse angle set square that occurs, it has a common feature: three angles all are wedge angles, do not have slick and sly transition between limit and the limit, wedge angle is sharper, in use or deposit and do not note slightly in the process scratching skin.In addition, in drawing or measuring process, usually need multiple set square collocation is used, but owing to there is not more convenient accommodation device, set square is often lost in use.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, a kind ofly be used to take in set square and avoid the wedge angle of set square to scratch the set square accommodation device of skin thereby the invention provides.
Technical scheme: for solving the problems of the technologies described above, set square accommodation device of the present invention, comprise and take in body, take in body and be provided with first groove, second groove and the 3rd groove, the profile and the right angle triangle of described first groove are suitable, the profile of described second groove and elongated set square are suitable, and the profile of described the 3rd groove and obtuse angle set square are suitable.
As preferably, described angle of taking in the body periphery is arc chord angle; The described body of taking in is a slab construction.
Beneficial effect: set square accommodation device of the present invention, by taking in setting and the suitable groove of different model set square on the body, can be so that deposit set square, in the process of using the set square drawing or measuring, can be with getting with usefulness, take sth. back where it was before to use up the back, can avoid set square to lose; In addition, be arc chord angle owing to take in the angle of body periphery, so, can avoid scratching skin carrying, use or depositing in the process.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
As shown in Figure 1, set square accommodation device of the present invention, comprise and take in body 4, take in body 4 and be provided with first groove 1, second groove 2 and the 3rd groove 3, the profile and the right angle triangle of first groove 1 are suitable, the profile of second groove 2 and elongated set square 3 are suitable, and the profile of the 3rd groove 3 and obtuse angle set square are suitable.
In the present embodiment, take in body 4 and be slab construction, the angle 5 of taking in body 4 peripheries is arc chord angle.Usually, be the rectangular configuration onesize, take in body 4 like this can carry as books with books with taking in body 4, very convenient.
Set square accommodation device of the present invention is put into first groove 1, second groove 2 and the 3rd groove 3 respectively with right angle triangle, elongated set square and obtuse angle set square in use, and be the set square storage configuration this moment; When needs use set square to draw or take measurement of an angle, from corresponding grooves, take out the set square that needs and get final product, with getting with usefulness, take sth. back where it was before after using up, very convenient, occurs the phenomenon that set square is lost never again.In addition, be arc chord angle owing to take in the angle 5 of body 4 peripheries, so, can avoid scratching skin carrying, use or depositing in the process.
The above only is a preferred implementation of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (4)
