Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of backpacks, in particular to a multifunctional portable schoolbag. BACKGROUND

[0002] Under the current educational environment, students are facing increasingly heavy academic pressure. In order to meet the daily learning needs, students need to carry a large number of textbooks, exercise books, stationery and other learning supplies. This has led to the design of student bags gradually tending to large capacity to accommodate a large number of learning items. Although these large and capable bags play an important role in meeting the daily learning needs of students, they have caused new problems in real life. When students need to go out, such as participating in research and travel activities, short-term study tours, etc., they often need to arrange and store the schoolbag in the luggage. However, due to the large size of the schoolbag, it occupies too much space in the luggage, greatly reducing the space utilization rate of the luggage, and bringing many inconveniences to the students' travel. This situation not only affects the convenience of carrying items when students travel, but also may require students to spend more time and effort to reasonably plan the space when arranging luggage, and even may have to discard some items that need to be carried due to lack of space. At present, there is a lack of effective solutions to the problem of the convenience of storing student bags when going out.

[0003] In order to solve the above problems, the present case arises. CONTENT OF THE UTILITY MODEL

[0004] Therefore, in view of the above problems, the utility model provides a multifunctional portable schoolbag for solving the problem of inconvenient storage and carrying of student bags.

[0005] To solve the above technical problems, the utility model adopts the following solution: a multifunctional portable schoolbag, comprising a bag body with a main storage space made by sewing a front piece, a back piece, a bottom piece and side pieces, a front pocket for providing a secondary storage space is sewn on the front piece, side pockets are sewn on the lower ends of the side pieces, a storage opening is provided on the upper end of the side piece, the storage opening extends to the side pockets at both ends respectively, an opening and closing zipper is sewn on the storage opening, a shoulder strap is fixedly provided on the back piece by sewing, upper and lower adhesive pieces are horizontally sewn on the inner surfaces of the top and bottom of the side pockets of the front and back pieces respectively, the upper and lower adhesive pieces form upper and lower rope passing channels with the front and back pieces, first rope passing openings are provided at both ends of the upper and lower rope passing channels of the front and back pieces, a hard pressing piece is movably arranged outside the side pocket, the top of the hard pressing piece is located at the top of the side pocket, and the bottom of the hard pressing piece is located at the bottom of the side pocket, second rope passing openings are provided on the four corners of the hard pressing piece respectively.

[0006] The front piece is provided with a front drawstring, and the rear piece is provided with a rear drawstring. Both the front and rear drawstrings are closed loops connected end to end and are non-elastic. The upper sections of the front and rear drawstrings are inserted into the upper drawstring channel, and the lower sections are inserted into the lower drawstring channel. The left and right sections of the front and rear drawstrings pass out of the first drawstring opening from the inside out and pass through the closest second drawstring opening from the inside out. The middle of the left and right sections of the front and rear drawstrings is located on the outer surface of the rigid pressure plate.

[0007] Two double-hole spring cord buckles are movably provided on the outer surfaces of the two rigid pressure plates respectively. The middle of the left and right sections of the front draw rope passes through one of the buckle holes of the two double-hole spring cord buckles on the same side, and the middle of the left and right sections of the rear draw rope passes through the other buckle hole of the two double-hole spring cord buckles on the same side.

[0008] A further improvement is that a rigid ring is fixedly installed on the first rope-threading opening to prevent it from cracking and wearing out.

[0009] A further improvement is that the rigid ring is made of hard plastic or metal.

[0010] A further improvement is that the material of the rigid pressing sheet is hard plastic or metal.

[0011] A further improvement is that the front and rear drawstrings are made of nylon ropes with a diameter of 3-6mm.

[0012] A further improvement is that a binding strip is sewn onto the seam edges between the front piece, back piece, bottom piece, and side pieces, and the two ends of the upper patch and lower patch are wrapped and sewn inside the binding strip.

[0013] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0014] 1. Traditional large-capacity student backpacks take up too much space when packed into suitcases. This multi-functional portable student backpack, when packed, has its upper part tucked into its lower part. The front and back drawstrings, along with double-hole spring rope buckles and a rigid pressure plate, compress the bag into a cylindrical shape, significantly reducing its space occupation in the suitcase and greatly improving space utilization. This allows students to carry more essential items when traveling.

[0015] 2. Binding strips are placed along the seams between the front, back, bottom, and side panels. This not only enhances the aesthetics but, more importantly, strengthens the overall structure of the bag. The ends of the upper and lower patches are wrapped and sewn inside the binding strips, further stabilizing the drawstring channel structure.

[0016] 3. The hard ring buckle fixedly arranged on the first rope passing port effectively prevents the first rope passing port from cracking and wearing, ensures that the rope will not affect the use due to the damage of the rope passing port during long-term use, and prolongs the service life of the schoolbag.

[0017] 4. The hard pressing sheet is made of hard plastic or metal material and has good rigidity, can effectively bear the tension of the rope and the deformation recovery force of the bag body during compression, is not easy to deform, and ensures the stability of the compression effect. The nylon rope has the characteristics of high strength and good wear resistance, and the inelasticity can better control the force and maintain the compression state during compression of the bag body, further improving the durability of the schoolbag.

[0018] 5. The portable compression storage method of the multifunctional portable schoolbag is simple to operate, whether the zipper is opened or not, the upper end of the bag body can be easily pressed into the lower end, then through the cooperation of both hands, one hand holds the front and rear ropes outside the hard pressing sheet, and the other hand presses the hard pressing sheet to the side to compress the bag body, and then adjusts the position of the double-hole spring rope buckle to fix the rope, which can complete the compression storage. This simple and easy operation method facilitates students to quickly complete the compression storage of the schoolbag. BRIEF DESCRIPTION OF DRAWINGS
