[0021] 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.

[0022] See also Figure 1-4 In this embodiment, a backpack with a back-adjusting and spine-protecting function includes a backpack body 1 , and an adjusting spine-protecting structure 2 is provided on the back of the backpack body 1 .

[0023] Specifically, a waist support 201 is fixedly connected to the back of the backpack main body 1, an elastic film 202 is fixedly connected to the back of the backpack main body 1, a limiting strip 203 is fixedly connected between the elastic film 202 and the backpack main body 1, a first Velcro 204 is connected to the top of the elastic film 202, an upper shoulder support 205 is fixedly connected to the back of the backpack main body 1, and a second Velcro 206 is fixedly connected to the outer surface of the upper shoulder support 205. By setting the waist support 201, the elastic film 202 and the upper shoulder support 205, it is beneficial to disperse the pressure on the user's waist, back and shoulders, reduce the user's sense of weight and protect the human spine. By setting different gear scales on the second Velcro 206, the curvature of the elastic film 202 can be adjusted with the cooperation of the first Velcro 204 to adapt to the carrying needs of different human body shapes.

[0024] Specifically, by fixing the breathable net 3 on the outer surface of the elastic film 202 , the backpack is more ventilated and breathable when carried, thereby improving the comfort of the user.

[0025] Specifically, by setting the second Velcro 206 as the Velcro thorn side and the first Velcro 204 as the Velcro fur side, the second Velcro 206 and the first Velcro 204 cooperate with each other to drive the top position of the elastic film 202 to be positioned. At the same time, by setting three levels of scales on the second Velcro 206, the curvature of the elastic film 202 is adjusted by utilizing the different fitting positions of the first Velcro 204 on the second Velcro 206.

[0026] Specifically, the interior of the waist support 201 is filled with sponge, and the outer surface of the waist support 201 is a mesh surface, so the structure is more stable and not easy to bend or deform, and is more comfortable and breathable.

[0027] During implementation, the following steps are performed: when carrying the backpack body 1, first carry the backpack body 1 on the shoulders through the shoulder straps, and then stick the first Velcro 204 to the appropriate gear of the second Velcro 206 according to your own body shape requirements. (In addition to using Velcro, the adjustment method of the elastic film 202 also includes: similar to some other plastic buckle adjustment methods, water drop hanging hole adjustment, etc.) to adjust the curvature of the elastic film 202, and finally make the waist support 201, elastic film 202 and upper shoulder support 205 fit the body shape comfortably, reduce the sense of weight and protect the spine.

[0028] In summary, the backpack with back adjustment and spine protection function is conducive to dispersing the pressure on the user's waist, back and shoulders, reducing the user's sense of weight and protecting the human spine by setting different gear scales on the second Velcro 206, and then with the cooperation of the first Velcro 204, the elastic film 202 is adjusted to adapt to the carrying needs of different human body shapes, so that the backpack has a higher fit with the human body and better support, which has the effect of reducing the load and protecting the spine. By setting the breathable net 3, the backpack is more ventilated and breathable when carried, which improves the comfort of use. It solves the problem that although some backpacks on the market have spine protection functions, they cannot be adjusted to the gears according to the carrying needs of different human body shapes, thereby reducing the fit to a certain extent.
