Description

Technical Field

[0001] The utility model relates to the technical field of backpacks, in particular to an adjustable, fitting and load-reducing backpack. Background Art

[0002] A backpack refers to a bag carried on the back. It is made of a variety of materials, including leather, plastic, polyester, canvas, nylon, cotton and linen. In an era where individuality is increasingly valued, various styles such as simplicity, retro, and cartoon also cater to the needs of fashionistas to express their individuality from different aspects. The styles of luggage have also expanded from traditional business bags, school bags, and travel bags to pencil cases, coin purses, and small sachets.

[0003] The places where the webbing is connected on the side of the current backpack structure are generally triangular, and the fixed type limits the width and has no adjustable space. When the backpack is carried, there is shaking and not fitting, the center of gravity deviates, and the inertia is large. Therefore, an adjustable fit and load-reducing backpack is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides an adjustable fit and load-reducing backpack, which has the advantages of improving the fit between the back and the human body and reducing shaking. It solves the problems of the current backpack structure in which the side connection straps are generally triangular, the fixed type limits the width, and there is no adjustable space. When carried, there are shaking, center of gravity deviation, and large inertia.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an adjustable, fit-reducing backpack, comprising a backpack body, two shoulder straps fixedly installed on the inner side of the backpack body, a support portion provided on the inner wall of the backpack body, a waist support installed on the inner wall of the backpack body, buckles installed on the ends of the two shoulder straps away from the backpack body, connecting belts installed inside the two buckles, webbing movably installed inside the two connecting belts, and storage knobs installed on the outer surfaces of the two connecting belts.

[0006] Preferably, a hand strap is fixedly installed on the top of the backpack body, and a backpack secondary pocket is installed on the outer surface of the backpack body.

[0007] Preferably, the two webbings both pass through the interior of the buckle and are fixedly connected to the surface of the waist support.

[0008] Preferably, the lumbar support is designed to be arc-shaped, and the lumbar support is designed to be adjustable.

[0009] Preferably, one end of the two connecting straps away from the buckle is fixedly connected to the surface of the backpack body.

[0010] Preferably, the interior of the support portion is filled with foam.

[0011] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0012] The adjustable fit and load-reducing backpack is constructed by arranging the coordination among the backpack body, shoulder straps, waist support, connecting straps, buckles, webbing and a storage knob. The webbing is moved by rotating the storage knob to pull the buckles. The movement of the webbing enables the waist support to fit the waist of the human body, thereby improving the fit between the back of the backpack body and the human body and reducing shaking, thereby achieving the effect of increasing the force-bearing area and protecting the spine and reducing the load. Thus, the existing technology solves the problem of solving the fitting problem by tying the waist belt, which is stuffy and inconvenient in summer. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-3 In this embodiment, an adjustable fit and load-reducing backpack includes a backpack body 1, two shoulder straps 2 are fixedly installed on the inner side of the backpack body 1, a support portion 5 is provided on the inner wall of the backpack body 1, a waist support 6 is installed on the inner wall of the backpack body 1, buckles 8 are installed on the ends of the two shoulder straps 2 away from the backpack body 1, connecting belts 7 are installed inside the two buckles 8, webbing 9 is movably installed inside the two connecting belts 7, and storage knobs 10 are installed on the outer surfaces of the two connecting belts 7.

[0019] It should be noted that the backpack body 1 refers to a bag carried on the back, and the materials are diverse, including bags made of leather, plastic, polyester, canvas, nylon, cotton and linen, etc.

[0020] A hand strap 3 is fixedly mounted on the top of the backpack body 1 , and a backpack secondary pocket 4 is mounted on the outer surface of the backpack body 1 .

[0021] By providing the shoulder straps 2 and the hand straps 3, the backpack body 1 is made multifunctional to carry, and can be carried on the back or carried by hand, which greatly improves the practicality and convenience of the backpack body 1. In addition, the backpack secondary pocket 4 is provided, and the backpack secondary pocket 4 is usually designed on the outside of the backpack, which is convenient for users to quickly access some commonly used items and can provide extra space for carrying more items.

[0022] Specifically, the inner walls of the two shoulder straps 2 are provided with shoulder pads, which are usually made of soft and elastic materials, such as high-density sponge, memory foam, etc., and can provide good touch and comfortable experience.

[0023] The two webbings 9 pass through the interior of the buckle 8 and are fixedly connected to the surface of the waist support 6. The ends of the two connecting straps 7 away from the buckle 8 are fixedly connected to the surface of the backpack body 1. The waist support 6 is arc-shaped and has an adjustable gasket design.

[0024] Specifically, by rotating the storage knob 10, the buckle 8 drives the webbing 9 to move. The movement of the webbing 9 makes the lumbar support 6 fit the human waist, improves the fit between the back of the backpack body 1 and the human body, reduces shaking, and achieves the effect of increasing the force area, protecting the spine and reducing the load. When the connecting belt 7 pulls the lumbar support 6, the two sides of the lumbar support 6 can move, so that the lumbar support 6 has a movable space, fits closely with the human waist, plays a supporting role, and increases the force area.

[0025] The interior of the support portion 5 is filled with foam.

[0026] Specifically, by filling the supporting portion 5 with appropriate materials, not only can the weight of the backpack body 1 be dispersed, but additional comfort and protection can also be provided.

[0027] During implementation, follow these steps:

[0028] 1) The backpack body 1 can be carried on the shoulders via two straps 2;

[0029] 2) Then, by rotating the storage knob 10, the twisting of the storage knob 10 pulls the buckle 8 to drive the webbing 9 to move, and the movement of the webbing 9 makes the waist support 6 fit the waist of the human body;

[0030] 3) Finally, the backpack body 1 is precisely fitted to the waist.

[0031] To sum up, the adjustable fit and load-reducing backpack is designed by arranging the coordination among the backpack body 1, shoulder strap 2, waist support 6, connecting strap 7, buckle 8, webbing 9 and storage knob 10. By rotating the storage knob 10, the buckle 8 drives the webbing 9 to move. The movement of the webbing 9 makes the waist support 6 fit the human waist, improves the fit between the back of the backpack body 1 and the human body, reduces shaking, and achieves the effect of increasing the force area, protecting the spine and reducing the load. It solves the problem that the existing technology solves the problem of fitting by tying the waist belt, and the problem of being hot and stuffy in summer and being inconvenient to use.
