Description

Simple assembled knapsack

Technical Field

The invention relates to a simple assembled backpack, belonging to the field of luggage leather, such as backpacks, schoolbags and the like.

Background

The case is very common in daily life, the appearance design and the manufacturing method of the case are fast to update, as the pursuit of people is endless and the innovation is ubiquitous, the pursuit of the case is child's schoolbag, the pursuit of novelty is child's nature, and the pursuit of continuous innovation is carried out on the change of style and shape of the schoolbag.

Disclosure of Invention

The invention aims to provide a schoolbag or a backpack which has simple structure, novel style and abstract shape and is popular with children.

The novel large-size back-protecting cap is composed of a cap slide, a large-size slide, a back-protecting strip and a side bag, wherein the cap slide and the large-size slide are connected through a zipper, the cap slide and the large-size slide are formed through pressing by a die, and the side bag is connected with the large-size by rivets.

The cover head slide glass is made by laminating a fabric and a lining material with an intermediate interlayer material, and the intermediate interlayer material is made of a plastic foaming material and has good buffering effect. The earthquake-proof heat insulation and moisture-proof. Chemical corrosion resistance and the like, and is pressed into a concave shape through a die.

The large body carrying sheet is made by laminating a fabric and a lining material with an interlayer material, and four folds are pressed on the large body carrying sheet through a mould.

The large-body carrying sheet is arranged in a T-shaped bilateral symmetry mode, so that later processing is simple.

The big body slide glass crease has the inclination to the axis is symmetry axis bilateral symmetry, and two creases lean out the upper end distance big in the centre, and the lower extreme distance is little, and two creases in the outside are leaned on inwards that the upper end distance is little, and the lower extreme distance is big, makes the package molding more pleasing to the eye through such design, and the upper end is thin, and the lower extreme is thick, and the upper end is wide, and the lower extreme is narrow.

The ridge protecting strip is made of two symmetrical foaming materials, the middle joint of the lower end of the ridge protecting strip is aligned with the joint edge of the back panel, and the ridge protecting strip can be machined and formed at one time during sewing, so that the manufacturing and the processing are simpler.

The side bag is made by laminating a fabric and a lining material with an interlayer material, two concave ingredients are formed by pressing through a die, and the two concave ingredients are connected through a zipper to form the side bag.

The technical scheme of the invention is as follows: the parts are made by laminating a fabric and a lining material, and are formed by pressing through a die, and the main body cover head and the large body are formed by one-step molding of two slide glasses through the die and are simply spliced by a zipper.

The invention has the beneficial effects that: simple structure, processing instant noodle because in earlier stage through mould press forming, simple two formula are assembled, and production machining efficiency is high, and the package is handsome in appearance.

Detailed Description

Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These exemplary embodiments are provided so that those skilled in the art can clearly understand the present invention and can implement the present invention according to the description herein. The drawings and detailed description are not intended to limit the invention, which is defined by the appended claims.

As shown in fig. 4, the cover head of the backpack is made by laminating a sheet of carrier sheet made of a fabric and a lining material, and the lining material is made of a plastic foam material and is pressed into a concave shape by a mold.

As shown in figure 5, the backpack body is made by laminating a carrying sheet made of a fabric and a lining material with an interlayer material, wherein the interlayer material is made of a plastic foaming material and is formed by pressing through a mold.

In the flat state, the spine guard strips are sewn to the large body slide with the center seam of the lower end aligned with the edge of the rear panel seam and the side pockets are riveted to the large body slide as shown in figure 9.

As shown in fig. 10, the large carrying sheet is turned over, the reverse side of the large carrying sheet faces outwards, the large carrying sheet is folded inwards, and a small part is sewn at the lower end of the large carrying sheet, so that the bag is turned over easily.

The bottom is sewn to the body hem as shown in fig. 11.

The back panel was turned upside down and the middle of the back panel was sewn as shown in fig. 12.

As shown in fig. 3, the backpack can be made by sewing the cover head and the body together with a zipper.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention.
