Description
Technical Field
The utility model relates to a stationery technical field especially relates to a novel writing case structure.
Background
The writing case is a case for students to hold pens, pencils, rulers, erasers and other stationery, and is mostly in a rectangular parallelepiped shape. The existing writing case consists of a case cover and a case body, and the double-layer writing case is provided with an upper case body and a lower case body. When the lower case body is opened to take out the stationery, the upper case body and the lower case body are completely separated and placed on the desktop to expose the lower case body, and the stationery in the case is easy to fall out and is inconvenient to use.
The study and life are relatively boring, the structural toy of the study and culture stationery used by students cannot be realized, so that the interest of the study and life is increased, and the design problem is solved at present.
Disclosure of Invention
An object of the utility model is to provide a double-deck stationery box compares with prior art's stationery box, and during the use, each part of this stationery box need not separate completely, and the stationery in the box is difficult to fall out, and it is very convenient to use. In addition, the structure of the stationery article used by the students is changed into a toy, so that the interest of study and life is increased.
In order to achieve the above purpose, the technical scheme of the utility model is that:
a double-layered writing case, comprising: the upper box body, the middle box body and the lower box body; wherein, the upper box body is provided with an upper box body positioning salient point and a rotating column; the middle box body is provided with a middle box body positioning salient point, a middle box body positioning hole and a middle box body through hole; the lower box body is provided with a lower box body positioning hole and a lower box body column hole;
the middle box body through hole is a groove-shaped through hole, and the rotating column can horizontally displace in the middle box body through hole.
When the writing case is in a closed state, the rotating column penetrates through the middle case body through hole to be fixed on the lower case body column hole, the upper case body positioning salient points are respectively embedded into the middle case body positioning holes, and the middle case body positioning salient points are embedded into the lower case body positioning holes.
When the middle box body of the writing case is in an open state, the upper box body rotates 90 degrees, the positioning salient points of the upper box body are separated from the positioning holes of the middle box body, and the stored stationery of the middle box body can be taken.
When the lower box body of the writing case is in an open state, the upper box body is rotated to 90 degrees rightwards, the upper box body positioning salient point and the middle box body positioning salient point are separated, then the middle box body is withdrawn backwards, the middle box body positioning salient point is separated from the lower box body positioning hole, and then the middle box body is rotated to 90 degrees rightwards; at this time, the stationery stored in the box body can be taken out.
The middle box body through hole is in sliding fit with the rotating column on the bottom surface of the upper box body. The rotating column on the bottom surface of the upper box body is in sliding fit with the column hole of the lower box body.
Compared with the prior writing case structure, the utility model has the advantages that: when the writing case is used, the case body can be opened only by rotating the relevant parts, all the parts are not required to be completely separated, the writing in the case is not easy to fall out, and the writing case is very convenient to use. In addition, the structure of the writing case is toy, so that the interest of students in learning and living is increased.
