Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention clearer and more obvious, the following description of the present invention with reference to the accompanying drawings and embodiments is provided for further details. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Example 1 is as follows:

referring to fig. 1 to 7, a backpack with an adjustable strap structure includes a backpack body 1 and straps 2, a containing cavity 3 is provided on the straps 2, and adjusting members 4 for independently adjusting the width and thickness of the straps 2 are provided on the straps 2, the adjusting members 4 are telescopically connected to the straps 2, the adjusting members 4 are placed in the containing cavity 3 when being folded, and the adjusting members 4 are widened from the width of the straps 2 when being unfolded.

The adjusting parts 4 have a connecting side connected with the braces 2 and a telescopic side capable of being freely adjusted, and the number of the adjusting parts 4 can also be flexibly designed according to actual requirements.

In this embodiment, the connection mode of the adjusting component 4 and the connection side of the shoulder strap 2 is sewing, and the telescopic side is opened and closed by turning or folding;

specifically, as shown in fig. 2 and 3, the adjusting member 4 includes a plurality of turning plates and a plurality of rotating shafts disposed on adjacent turning plates, the turning plates are rotatably connected through the rotating shafts, wherein the turning plate located at the innermost side of the shoulder strap is sewn and fixed with the shoulder strap.

Alternatively, as shown in fig. 4-7, the adjusting member 4 may be of a fold-over type: the adjusting part 4 is in a superposition state when being folded to form a superposition layer 5; when the folding strap is opened, one side of the adjusting part 4 is connected to the strap 2, the other side of the adjusting part is movably pulled open the folding layer 5, and the folding layer 5 is wider than the width of the strap 2;

specifically, as shown in fig. 4-5, when there are two adjusting components 4, the two adjusting components are respectively placed in the strap 2 and close to the middle of the strap 2, one side of the adjusting component 4 close to the middle of the strap 2 is fixed on the strap 2 for superposition, the other side of the adjusting component 4 is folded towards one side close to the middle of the strap 2, the number of superposed layers is greater than 2, the thickness of the strap 2 is thickened, the pressure of the bag body on the human body is absorbed to a certain extent, and the effect of pressure reduction is achieved; when the backpack feels pain of shoulder and the pressure is too high, the backpack is opened outwards, one side of the adjusting component 4, which is far away from the middle part of the shoulder strap 2, is wider than the width of the shoulder strap 2, and the width of the backpack strap is widened, so that the contact area of the backpack and the shoulder is widened, and the discomfort caused by too high local stress of the shoulder of a human body is reduced.

As shown in fig. 6-7, when there is one adjusting component 4, the middle part of the adjusting component 4 is arranged in the middle of the back belt 2 for folding, and both sides of the adjusting component 4 are respectively folded towards the middle part, and the number of layers for folding is more than 2 (preferably 2-3); when the backpack feels the pressure intensity too large, the backpack is opened outwards, and the two sides of the adjusting part 4 are respectively wider than the left side and the right side of the braces 2. Thus, when the backpack is folded, the thickness of the strap 2 can be thickened by the folding sheet, the pressure of the backpack body on the human body can be absorbed to a certain degree, and the effect of pressure reduction is achieved. When the folding layer 5 is opened outwards, the width of the shoulder strap 2 is widened, so that the contact area of the backpack and the shoulder is widened, and the discomfort caused by over-large local stress on the shoulder of a human body is reduced.

Example 2 is as follows:

it differs from example 1 in that: the adjusting part 4 is connected with the braces 2 in a buckling mode, and the adjusting part 4 is opened and closed in a rotating mode. One side of the adjusting component 4 is connected with the side edge of the brace 2, and the other side is movably wider than the width of the brace 2.

Specifically, as shown in fig. 8, when there is one adjusting member 4, it is disposed on one of the left and right sides of the shoulder strap 2 and is rotatably connected to the shoulder strap 2; when the backpack is opened, the adjusting component 4 rotates and moves towards any side of the shoulder strap 2 to widen the shoulder strap 2, thereby widening the contact area between the backpack and the shoulder and reducing the discomfort caused by the over-large local stress on the shoulder of the human body.

As shown in fig. 9, when the two adjusting members 4 are provided on the left and right sides of the shoulder strap 2, respectively, when the adjusting members 4 are opened, the adjusting members 4 are rotated and moved to the both sides of the shoulder strap 2, respectively, to widen the shoulder strap 2, thereby further widening the contact area between the backpack and the shoulder and reducing the discomfort caused by the local stress on the shoulder of the human body.

Preferably, the side of the adjusting part 4 contacting with the human body is provided with an arc-shaped surface to be more suitable for ergonomics and the backpack is more comfortable to use.

The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
