Abstract

The utility model provides a multipurpose school bag with simple structure and good service performance, which comprises a lower bag body, a middle bag body connected with the lower bag body and an upper bag body connected with the middle bag body. The bag is characterized in that: both the lower and middle bag body are hollow bodies each has an opening on one side; the middle bag body is a groove shaped frame; the widths of both the lower and middle bag body are larger than that of the groove of the middle bag body; the upper and lower bag body are connected with the middle bag body respectively by a first and second rotary shaft; the distance between the second rotary shaft and bottom plane of the groove of the middle bag body is larger than half of the thickness of the lower bag body; the distance between the first rotary shaft and bottom plane of the groove of the middle bag body is larger than the sum of thickness of the lower bag body and half of the upper bag body. By adopting the rotary shaft connection form with fixed structure, the bag of the utility model can realize convenient folding and unfolding, and can utilize the space on both sides of desk reasonably.

Description

A kind of school bag of using more

Technical field

The utility model relates to a kind of school bag, in particular, relates in particular to a kind of collapsible also extensible school bags of using more.

Background technology

Present high school student's books are considerable, the student always piles up books on the desk at school the time, the major part of this desk that not only accounted for, but also influence the study of students, present student's major part all can be carried school bag and go to school, can only put in the drawer face but school bag has arrived in the school, this not only can account for certain space, but also can not get up the space reasonable use of school bag itself; The area of considering the classroom is limited, and can not changing of the size of existing desk is big, but the space of outside, desk two ends does not also have reasonable use.

Summary of the invention

The utility model has overcome the shortcoming of above-mentioned technical problem, and a kind of school bag of using with simple structure and good serviceability is provided more.

For achieving the above object, the utility model has adopted following technical scheme:

The school bag of using of the present utility model more, comprise lower wrapping body, middle inclusion that is connected with lower wrapping body and the upper wrapping body that is connected with middle inclusion, it is characterized in that: described lower wrapping body and middle inclusion are the cavity body of an opening, inclusion is the framework of a groove shape structure in described, the width of inclusion groove during the width of described lower wrapping body and middle inclusion all is not more than, described upper wrapping body and lower wrapping body are connected on the middle inclusion by first turning cylinder and second turning cylinder respectively, the distance of inclusion groove baseplane is greater than half of lower wrapping body thickness in described second turning cylinder distance, and the distance of inclusion groove baseplane is greater than lower wrapping body thickness and half sum of upper wrapping body thickness in described first turning cylinder distance.

Many school bags of use of the present utility model, described in inclusion be provided with the upper wrapping body that is used for fixing after folding and the fixed band of lower wrapping body, also be provided with braces on the described middle inclusion.

Use school bag of the present utility model, first turning cylinder wherein and second turning cylinder pass from the centre position of upper wrapping body and lower wrapping body height respectively more, and described upper wrapping body and lower wrapping body all can rotate around axle separately; Distance between described first turning cylinder and second turning cylinder is greater than the length of lower wrapping body, so that lower wrapping body can fold in the groove that enters middle inclusion easily.

The beneficial effects of the utility model are: adopt the fixing turning cylinder type of attachment of structure, can realize the folding and expansion of convenience of school bag of the present utility model; Can on desk, launch, and can deposit a large amount of books, rationally utilize the space of desk both sides.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Among the figure: 1 lower wrapping body, inclusion in 2,3 upper wrapping bodies, 4 first turning cylinders, 5 cavitys, 6 second turning cylinders, 7 ligulate bars, 8 fixed bands, 9 braces.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.

Fig. 1 has provided structural representation of the present utility model, as shown in the figure, shown upper wrapping body 3 is the casing of an end face opening, the first shown turning cylinder 4 is arranged on the centre position of upper wrapping body 3 openends, first turning cylinder 4 runs through on the two sides of the middle inclusion 2 shown in being fixed on behind the upper wrapping body 3, middle inclusion 2 is the structure of groove shape, shown lower wrapping body also is the casing of an end face opening, the second shown turning cylinder 6 is through the openend of lower wrapping body 1 and be fixed on the ligulate bar 7, shown ligulate bar 7 is the extension of middle inclusion two sides, shown upper wrapping body 3 and lower wrapping body 1 can rotate around first turning cylinder 4 and second turning cylinder 6 respectively, the distance of inclusion groove floor is greater than half of lower wrapping body thickness in shown second turning cylinder distance, so that lower wrapping body is collapsible in the middle inclusion groove, the distance of inclusion groove floor is greater than middle inclusion 2 thickness and half sum of upper wrapping body thickness in a shown low turning cylinder 4 distances, so that after inclusion 2 grooves, upper wrapping body 3 also can fold into the top of lower wrapping body smoothly in lower wrapping body 1 folding entering.

One sidewall of shown middle inclusion is provided with a fixed band 8, the effect of this fixed band 8 be when shown in lower wrapping body 1 and upper wrapping body 3 all fold in after the inclusion groove, lower wrapping body 1, middle inclusion 2 and upper wrapping body 3 are fixed together, also be provided with a braces on the two sides of shown middle inclusion 2, when people need move the utility model, carry convenience very by braces.

In process practical in the classroom, only need lie in a horizontal plane in middle inclusion 2 on the desk, then fixed band 8 is untied, again lower wrapping body 1 and upper wrapping body 3 are folded open, lower wrapping body 1 and upper wrapping body 3 hung down get final product at the two ends of desk, in this case, can place study articles such as books in the groove of shown middle inclusion 2, shown lower wrapping body 1 and upper wrapping body 3 all can be placed books.
