Abstract
The utility model relates to a three-dimensional both shoulders prevent schoolbag at books book corner, its main characterized in that is equipped with the spring expansion bracket on the preceding facade in the schoolbag, is equipped with the spring expansion plate on the spring expansion bracket, and it is corresponding with the magnetism box on preceding facade upper portion to be equipped with magnetism son on the upper cover. The main purpose of the utility model is to prevent the books in the schoolbag from rolling corners or folding, etc., and keep the books neat and beautiful.
Description
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;
Fig. 5 is the utility model magnetic box structural representation.
To be described in further detail concrete structure of the present utility model and embodiment below in conjunction with accompanying drawing.
Shown in accompanying drawing 1-5, school bag is stereoscopic-state, it is by preceding facade 7, back facade 11, left surface 8, right flank 9, bottom surface 10, loam cake 6, book strap 2 is formed, on the skin of preceding facade 7, has the little pocket of convex, on little pocket, has the pin of drawing 1, at left surface 8, has rectangle pocket 5 on the right flank 9 respectively, it is corresponding with the magnetic box 3 of preceding facade 7 top the right and lefts to have identical magnetic button 4 respectively at loam cake 6 front end the right and lefts, the structure of magnetic button 4 is to have magnet 21 on the right flank of sheet metal 22, left surface has reflector 23 and is connected as a single entity, the structure of magnetic box 3 is cans 20 outside being with in lining can 19, on the left and right sides, middle part of the medial surface of preceding facade 7, has identical telescopic spring frame 13 respectively, it is corresponding with back facade 11 medial surfaces to have telescopic spring plate 12 on telescopic spring frame 13, preceding facade 7 bottoms have hinge 14 and are connected with bottom surface 10 front ends, the promptly preceding facade 7 of school bag shell mechanism, back facade 11, left surface 8, right flank 9, bottom surface 10, the concrete structure of loam cake 6 is, be respectively lining fabric 15 from inside to outside, hardboard 16, sponge 17, appearance cloth 18 is formed, and loam cake 6 also is that hinge is connected with back facade 11.
