Description

Technical Field

[0001] The utility model belongs to the technical field of school bags, and in particular relates to a height-adjustable backpack with a spine protection system. Background Art

[0002] At present, the common backpacks on the market all use fixed rigid shoulder straps or two aluminum bars installed on the upper and lower sides of the back as sliding tracks, and the height of the shoulder straps can be adjusted through the tracks on both sides. These adjustment systems first increase the weight of the backpack and the complexity of the back, and the operability is very low. In addition, due to the hardness of the aluminum bars, it is easy to hit the back of the wearer, hurting the wearer or making the wearer feel uncomfortable. The key is that the aluminum bar frame undoubtedly makes the backpack very bloated and heavy to carry, the bag body is stiff, reducing the load capacity of the backpack and increasing the pressure on the shoulders and waist of the wearer. For backpacks with rigid shoulder straps and no adjustment system, due to the limitation of the length of the fixed shoulder straps and the hardness of the shoulder straps, the load pressure is concentrated on the shoulders and spine, which seriously affects the load and waist health of the wearer, and at the same time limits the needs of different wearers, such as the different needs of different age groups and different torsos for shoulder strap length. Utility Model Content

[0003] The utility model aims to provide a height-adjustable backpack with a spine protection system to solve the technical problem that the traditional backpack exerts uneven pressure on the waist and back and easily causes scoliosis.

[0004] In order to solve the above technical problems, the specific technical solutions of the utility model are as follows:

[0005] In some embodiments of the present application, a height-adjustable backpack with a spine protection system is provided, comprising:

[0006] A main body, wherein a first connection end and a second connection end are provided at the back of the main body;

[0007] A support component, wherein the support component is disposed on the back of the main body, the bottom of the support component is movably connected to the bottom of the main body, and a third connection end arranged symmetrically is provided on the support component, and the third connection end is connected to the first connection end through the third connection end;

[0008] A positioning component, which is arranged on the main body and is fixedly connected to the main body, and has a positioning end thereon;

[0009] The positioning component is also provided with fourth connecting ends which are symmetrically arranged;

[0010] The shoulder strap component is arranged between the main body and the supporting component, and is provided with a symmetrically arranged fifth connection end, which is connected to the second connection end through the fifth connection end, and the extension belt on the shoulder strap component passes through the fourth connection end and comes out.

[0011] In some embodiments of the present application, symmetrically arranged support plates are provided inside the support component, and a flexible layer is provided on the surface of the support plates.

[0012] In some embodiments of the present application, a waist pad is also provided at the bottom of the front side of the support component.

[0013] In some embodiments of the present application, the top of the supporting component is connected to the positioning end of the positioning component.

[0014] In some embodiments of the present application, the first connection end, the second connection end, the third connection end, and the fifth connection end are Velcro structures.

[0015] In some embodiments of the present application, a height indicator is also provided between the second connection ends.

[0016] Compared with the prior art, the beneficial effect of the utility model lies in that, by adding a height indicator, the connection position between the shoulder strap component and the main body can be adjusted according to the height of the user, thereby adjusting the pressure balance of the backpack on the back of the human body; by adding a supporting component and adopting symmetrically arranged support plates, the back of the human body is supported by the support plates to avoid excessive bending of the spine; and by adding a waist pad, the waist is supported at the same time, so that it can fit the curve of the human spine when in use, avoiding the problem of scoliosis caused by unbalanced pressure of the backpack on the human body.

[0025] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0027] See attached Figure 1-7 As shown, according to some embodiments of the present application, it includes:

[0028] A main body 1, wherein a first connection end 101 and a second connection end 102 are provided at the back of the main body 1;

[0029] The support component 2 is a back plate structure, and the support component 2 is arranged on the back of the main body 1. The bottom of the support component 2 is movably connected to the bottom of the main body 1, and a symmetrically arranged third connection end 203 is provided on the support component 2, which is connected to the first connection end 101 through the third connection end 203, that is, the main body 1 and the support component 2 are integrated or formed into an integrated structure through other connecting parts, and the support component 2 can be folded;

[0030] The positioning component 4 is a belt-shaped structure, which is arranged on the main body and is fixedly connected to the main body 1. A positioning end 401 is provided on the positioning component 4; the positioning component 4 is also provided with a symmetrically arranged fourth connection end 402 (the fourth connection end 402 is a ring, that is, the positioning component 4 forms a sandwich structure with the main body 1 at the position of the fourth connection end 402);

[0031] The shoulder strap component 3 is a shoulder strap rope. As shown in the figure, the shoulder strap component 3 is arranged between the main body 1 and the supporting component 2, and is provided with a symmetrically arranged fifth connection end 301, which is connected to the second connection end 102 through the fifth connection end 301, and the extension belt thereon passes through the fourth connection end 402 and comes out.

[0032] It should be noted that a symmetrically arranged support plate 201 is provided inside the support component 2, and a flexible layer (such as sponge, silica gel, etc.) is provided on the surface of the support plate 201. A waist pad 202 is also provided at the bottom of the front of the support component 2. The top of the support component 2 is connected to the positioning end 401 of the positioning component 4.

[0033] It should be further explained that the first connection end 101 , the second connection end 102 , the third connection end 203 , and the fifth connection end 301 are Velcro structures, and an altitude indicator 103 is also provided between the second connection ends 102 .

[0034] When in use, the position of the fifth connection end 301 and the second connection end 102 of the shoulder strap component 3 is adjusted according to the height of the user, and the positioning is performed according to the height indicator 103 between the second connection ends 102. After the shoulder strap component 3 is connected, the third connection end 203 of the support component 2 is connected to the first connection end 101 on the main body 1 to complete the assembly, and then the backpack is carried on the human body. At this time, the support plate 201 inside the support component 2 supports the back, and the waist pad 202 supports the waist. Since the position of the shoulder strap component 3 has been adjusted, the pressure on the shoulder is balanced and the spine will not bend. It should be noted that in order to further improve the overall effect, a waist belt 5 is also provided at the bottom of the main body 1, and a chest belt 6 is also provided on the shoulder strap component 3. Since the waist belt 5 and the chest belt 6 have been involved in the prior art, they are not repeated here.
