[0002] The shoulder straps of most backpacks can be adjusted in length by means of an adjustment strap or drawstring. Usually, there will be one or more adjustment buckles at the connection of the shoulder straps. By pulling these adjustment buckles, the shoulder straps can be extended or shortened to make them more suitable for the user's height and shoulder width.

[0003] Traditional backpack shoulder straps are usually adjusted in length through fixed buckles, which is clumsy and time-consuming when quick adjustments or storage are needed. In crowded public transportation, long shoulder straps may drag on the ground or hook other objects, causing inconvenience or danger. With the increase in outdoor activities and urban commuting, the demand for convenience and comfort of backpacks is getting higher and higher. Therefore, a multi-adjustable fit and load-reducing backpack is proposed. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a multi-adjustable fit-reducing backpack with the advantages of being beautiful and comfortable. It solves the problem that the length of traditional backpack shoulder straps is usually adjusted by fixed buckles, which is clumsy and time-consuming when quick adjustment or storage is required. In crowded public transportation, long shoulder straps may drag on the ground or hook other objects, causing inconvenience or danger. With the increase in outdoor activities and urban commuting, the demand for convenience and comfort of backpacks is getting higher and higher.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a multi-adjustable fit-reducing backpack, comprising a backpack main body, two fixing straps fixedly installed on the front side of the backpack main body, knobs fixedly installed on the bottom of the two fixing straps, two corner straps fixedly installed on the front bottom of the backpack main body, adjustment straps are arranged between the two knobs and the corner straps, and a waist pad is arranged on the front bottom of the backpack main body.

[0018] 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.

[0019] Example 1: Please refer to Figure 1 In this embodiment, a multi-adjustable fit-reducing backpack includes a backpack main body 2, two fixing straps 1 are fixedly installed on the front side of the backpack main body 2, and knobs 3 are fixedly installed on the bottom of the two fixing straps 1. Two corner straps 9 are fixedly installed on the front bottom of the backpack main body 2, and adjustment straps 4 are arranged between the two knobs 3 and the corner straps 9. A waist pad 7 is arranged on the front bottom of the backpack main body 2.

[0020] A guide sleeve 8 located on the outer surface of the adjustment strap 4 is fixedly mounted on the front side of the backpack body 2 .

[0021] In order to improve the convenience and aesthetics of adjusting the fixing strap 1, a knob 3 is introduced in this design to adjust the fixing strap 1. The knob 3 not only simplifies the adjustment process, but also avoids the operational inconvenience that may be caused by traditional buckles. By setting a guide sleeve 8, the adjustment strap 4 can move smoothly during the adjustment process, and the excess adjustment strap 4 can be cleverly hidden, thereby improving the visual aesthetics.

[0022] The working principle of the knob 3 is to achieve the storage and length adjustment of the adjustment strap 4 through the internal mechanical structure. When the user rotates the knob 3, its internal structure will rotate accordingly, thereby pulling or releasing the adjustment strap 4 to adjust the length of the shoulder strap.

[0023] Specifically, the knob 3 includes a component similar to a scroll or a gear, which is connected to the adjustment belt 4. When the knob 3 is rotated, this component will rotate accordingly, winding in or releasing the adjustment belt 4, thereby adjusting the length. At the same time, this design also ensures that during the adjustment process, the excess adjustment belt 4 can be effectively stored to maintain the neatness of the overall appearance.

[0024] Example 2: Please refer to Figure 2 and Figure 3 A multi-adjustable fit-reducing backpack includes a backpack main body 2, two fixing straps 1 are fixedly installed on the front side of the backpack main body 2, and knobs 3 are fixedly installed on the bottom of the two fixing straps 1. Two connecting straps 5 are fixedly installed on the front bottom of the backpack main body 2, and Japanese buckles 6 are provided on the tops of the two connecting straps 5. Adjustment straps 4 are provided between the two Japanese buckles 6 and the knobs 3, and a waist pad 7 is provided on the front bottom of the backpack main body 2.

[0025] The waist pad 7 has an arc-shaped structure, and guide sleeves 8 located on the outer surface of the adjustment belt 4 are fixedly installed on the left and right sides of the waist pad 7. By setting the guide sleeves 8, a fixed channel is provided for the adjustment belt 4, so that the adjustment belt 4 can move along the guide sleeves 8. When adjusting the adjustment belt 4, the waist pad 7 is pulled to fit the user's waist, supporting the waist and improving comfort.

[0026] One end of the two adjustment straps 4 passes through the Japanese-shaped buckle 6 and is fixedly connected to the front side of the backpack body 2. The Japanese-shaped buckle 6 connects the force points at the end and the bottom. The width can be freely adjusted according to people of different body shapes by adjusting the knob 3 and pulling it to the Japanese-shaped buckle 6. The connection point at the other end of the adjustment strap 4 is fixed to the backpack body 2. This layout forms an adjustable triangular structure, which helps to disperse the pressure caused by the backpack load. This structure helps to dynamically adjust the force points when the user is active, especially when walking or running, and can effectively stabilize the position of the backpack and reduce shaking, thereby reducing the extra burden caused by the shaking of the backpack.

[0027] To sum up, the multi-adjustable fit-reducing backpack, through the design of the knob 3, the user can easily rotate to adjust the tightness of the fixing strap 1. This design not only simplifies the adjustment process, but also avoids the operational inconvenience that may be caused by traditional buckles. The use of the knob 3 effectively avoids the problem of the adjustment strap 4 being too long and exposed, thereby increasing the safety and neatness of the device. The application of the guide sleeve 8 further ensures that the redundant adjustment strap 4 is cleverly hidden, thereby enhancing the overall visual and practical effects.

[0028] In addition, the combined use of the knob 3, the adjustment strap 4, the connecting strap 5 and the Japanese-shaped buckle 6 allows the adjustment strap 4 to flexibly move within the Japanese-shaped buckle 6, and is pulled by the connecting strap 5 to form a triangular multi-point support structure, which helps to evenly distribute the weight of the backpack. This structural design not only improves the fit of the backpack body 2 to the body, but also creates multiple dispersed force points, effectively reducing the pressure on the shoulders and back, allowing the wearer to feel a more obvious load-reducing effect during use.
