Description

The case of student's drawing tools

Technical field

The utility model relates to a kind of case more particularly to a kind of cases of student's drawing tools.

Background technique

Currently, the spare drawing tools of student is usually to be stored in school bag or in a box body, the former is drawing tools It is stored in school bag together with books, drawing tools is stored in school bag together with books no doubt can be with, still, books and draws Collision is easy to happen between tool；The latter is drawing tools to be stored in a box body, and drawing tools is stored in box body, It is seen on surface, box body can play a protective role to the drawing tools of its inside, and still, for school bag when shaking, then box is intracorporal Ruler, compasses and protractor will mutually be hit.

Summary of the invention

In order to overcome the shortcomings of that existing drawing tools is existing in storage, the utility model provides a kind of student's picture The case of tool is equipped with one along one annular insert edge of upright setting, the cavity of box body in the upside of the case box body Rectangular cavernous body, and the uper side surface interval of cavernous body uniformly scrapes out a ruler low water, a protractor from top to bottom Low water and a compasses low water.

The technical scheme adopted by the utility model to solve the technical problem is as follows: including box cover and box body, rectangular box Equipped with a compatible box cover, also, box cover and box body are set up by the plastic material of environment-friendly type, box cover by four baffles with One panel composition, the reverse side outer of panel are set there are four baffle, and four baffles surround the reverse side of panel, the length and box of box body The length of lid is 34cm, and the width of box body and the width of box cover are 5cm, and the height of box body is four times of box cover height, box The height of body is 12cm, and the upside in box cover cavity is equipped with one layer of rubber, and edge is vertically arranged an annular and inserts in the upside of box body The height on side, annular insert edge is consistent with the depth in box cover cavity, and the length and width of annular insert edge are equal in box cover cavity Length and width, that is to say, that the internal cavities of box cover be only limitted to box body top annular insert edge insertion, four upper lateral part of box body Thickness-annular insert edge four sidewall bodies of thickness=box cover thickness；One rectangular cavernous body is set in the cavity of box body, On the outside of four sides of cavernous body and bottom is with bottom in four sidewall bodies being bonded in box body cavity, and the height of cavernous body is lower than box Depth in body cavity, the surface interval of cavernous body uniformly scrape out from top to bottom a compasses low water, protractor low water with One ruler low water, also, the bottom of each bar shaped low water does not penetrate the bottom of corresponding position cavernous body, only may be used in ruler low water The ruler that length is 30cm is put, this ruler is the common ruler of most of students, only be can be placed in compasses low water one long Degree is no more than the compasses of 20cm, and the compasses of 15cm-18cm long are the common compasses of most of students, can be simultaneously in protractor low water A protractor and two set squares are put, protractor is that trumpet is set up with each set square, that is to say, that protractor low water It is interior to be placed in student common one small size protractor and two small size set squares, in addition, the wall body in each low water can be in Flexible shape is shunk and expansion；The horizontal side of compasses in reeve compasses low water, protractor is aligned with each set square fold after, And side imbed in protractor low water, the horizontal side of ruler in merging ruler low water, after box cover covers box body from top to bottom, At this moment, four sides of box cover are neat as the outside of corresponding position box body.

The utility model has the beneficial effects that the surface interval of cavernous body uniformly scrape out from top to bottom a compasses low water, One protractor low water and a ruler low water, the wall body in each low water cavity can be shunk inward in flexible shape to be extended out with past , that is to say, that when storing, the outside of ruler, compasses and protractor can be got into inward by outside, on the contrary, their outside Low water inner wall jam-packed after being expanded；After each drawing tools is respectively implanted the internal cavities of corresponding position low water, and it is each It is to be put down as the surface of corresponding position cavernous body on the outside of one side of drawing tools, sets up in this way, first is that in each low water cavity Two sides can choke on the outside of the one side of corresponding position drawing tools, that is to say, that the two sides wall body in each low water can be effective Protection corresponding position drawing tools one side on the outside of, second is that just to take out each drawing tools.
