Description

Schoolbag with book protective function

The utility model relates to the school bag that a kind of students in middle and primary schools use, and especially a kind of three-dimensional both shoulders prevent the school bag at books volume angle.

School bag is the essential product that the student often uses, especially students in middle and primary schools wish thing maintenance neat appearances such as pen, basis, book in oneself the school bag, but the school bag of selling on city's field boundary is that soft cloth is done mostly at present, when book, originally pack in the school bag, be easy to the corner of books foldingly, the time has been grown, book is unlike individual book sample, this has also become reel, not only uses inconvenience, seems also very not attractive in appearance.

The purpose of this utility model provides a kind of school bag that can make books keep neat appearance.

The utility model is achieved in that to have identical telescopic spring frame respectively on the left and right sides, middle part of the medial surface of preceding facade, on the telescopic spring frame, have the telescopic spring plate, have identical magnetic in the loam cake front end left and right sides respectively and detain corresponding with the magnetic box of preceding facade top the right and left.

During use, magnetic button is opened in the magnetic box, loam cake turns over backward, and preceding facade is set level forward, with books come into line stand up the back facade in, more preceding facade is boosted and since preceding facade on have the telescopic spring device, compressive plate is withstood books, keep books neat, do not roll up the angle and fold.

The utility model compared with prior art has following advantage:

1, prevents books volume angle, neat appearance;

2, reasonable in design, compact conformation is easy to promote the use of;

3, owing to have reflector on the school bag, when walking night, can cut down traffic accidents.

The utility model concrete structure and embodiment are provided by the following drawings.

Fig. 1 is the utility model overall structure schematic diagram;

Fig. 2 is that the utility model launches schematic diagram;

Fig. 3 is that the utility model A-A cuts open and shows schematic diagram;

Fig. 4 is the sub-buckle structure schematic diagram of the utility model magnetic;
