Schoolbag with classification cards

Abstract

The invention provides a schoolbag with classification cards. Soft cushion blocks connected to the front wall and the rear wall of a book containing space are arranged on the inner side of the schoolbag bottom; cushion block side channels extending to the front wall and the rear wall of the book containing space are reserved beside the soft cushion blocks, books are borne on the upper surfaces ofthe soft cushion blocks and cannot enter the cushion block side channels, and rails connected to the front wall and the rear wall of the book containing space are arranged in the cushion block side channels. Classification cards extending towards the left wall and the right wall of the schoolbag are further arranged in the schoolbag, protruding tongues extending into the cushion block side channels are arranged at the bottoms of the classification cards, sleeving and hanging devices are arranged on the protruding tongues, and the rails are matched with the sleeving and hanging devices to limitthe classification cards to move towards the schoolbag opening and allow the classification cards to slide towards the front wall and the rear wall of the book containing space. The schoolbag is light in weight; the classification cards only occupy a small space in the schoolbag, have little influence on free change of the thickness of a flexible schoolbag, facilitate classification of books in the schoolbag, and provide better protection for the books.

Description

technical field [0001] The invention relates to a school bag with sorting cards, which belongs to the technical field of school bags. Background technique [0002] At present, schoolbags mainly rely on the built-in compartments for front and rear partitions to classify books. This kind of partition is usually connected flexibly with the side walls of the schoolbag or the bottom of the schoolbag. Its essence is to allow the partition to move by the folding and stretching of the flexible connecting material. The disadvantage of this structure is that the overall movement range of the partition to the front and rear walls of the schoolbag is limited. , when there are many books placed between the two compartments, the middle part of the compartment will bulge; in addition, the compartments are mostly in the form of cloth-wrapped stiff cards, which are heavy and costly, so the number of compartments in school bags is generally small. In addition, my invention patent No. ZL20091...

This kind of partition is usually connected flexibly with the side walls of the schoolbag or the bottom of the schoolbag. Its essence is to allow the partition to move by the folding and stretching of the flexible connecting material. The disadvantage of this structure is that the overall movement range of the partition to the front and rear walls of the schoolbag is limited. , when there are many books between the two compartments, the middle part of the compartment will bulge; in addition, the compartments are mostly in the form of cloth-wrapped stiff cards, which are heavy and costly, so the number of compartments in school bags is generally small

In addition, my invention patent No. ZL200910180715.9 stretchable schoolbag management box series effectively solves the overall front and back sliding of the classification cards, but because the bottom adopts a rigid stretchable structure, it is difficult for the expansion and contraction of the overall thickness of the flexible schoolbag and the flexibility of the schoolbag. Weight still matters
