[0028] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0029] like Figure 1-6 As shown, the utility model discloses a back protection backpack, comprising a bag body 1 and two shoulder straps 2, a first cushion block 4 and a second cushion block 5 are protrudingly provided at a rear panel 3 of the bag body 1, and hanging rings 6 are fixedly provided on both sides of the upper part of the rear panel 3.

[0030] At least two first cushion blocks 4 are provided, and are respectively located on both sides of the upper part of the rear panel 3 to correspond to the left shoulder blade and the right shoulder blade of the human body, and the second cushion block 5 is located below the first cushion block 4 to correspond to the waist of the human body. The first cushion block 4 and the second cushion block 5 are both made of elastic material, and can cushion and decompress the shoulder blade area and waist of the human body when the backpack is used, and evenly distribute the weight of the backpack on both sides of the spine, so that the two sides of the spine are subjected to the same force, thereby protecting the spine.

[0031] In this embodiment, two first pads 4 are symmetrically arranged, and the two first pads 4 are spaced apart. The second pad 5 corresponds to the entire waist, and the first pad 4 and the second pad 5 are also spaced apart. At this time, a cross-shaped ventilation groove 19 is formed between the first pads 4 on both sides and between the first pad 4 and the second pad 5, which can leave a certain space for air circulation when carried on the back, play a role in sweating and cooling, and improve the comfort of use. Similarly, a plurality of strip holes 8 are opened on the first pad 4 and / or the second pad 5, and the strip holes 8 are arranged to penetrate in the direction of the bag body 1, which can also play a certain ventilation role and avoid the stuffiness and discomfort caused by being close to the human body.

[0032] The two shoulder straps 2 are distributed on both sides of the bag body 1, and the upper ends of the two shoulder straps 2 are connected to the hanging rings 6 through the connecting belts 7, and then connected to the two sides of the upper part of the back panel 3 respectively. When connected, the connecting belt 7 passes through the hanging ring 6, and both ends are fixedly connected to the shoulder straps 2, and the ends of the shoulder straps 2 can be rotatably connected to the hanging ring 6, and the lower ends of the two shoulder straps 2 are connected to the two sides of the lower part of the back panel 3 through webbing and Japanese buckles.

[0033] By rotating the bag body 1 through the hanging ring 6, the angle of the shoulder strap 2 relative to the bag body 1 can be adjusted in real time, so as to adapt to different shoulder widths and provide a comfortable carrying experience for users with different shoulder widths. Adjusting the shoulder strap 2 to a suitable and comfortable position can effectively reduce unilateral or local pressure, distribute the weight of the backpack more evenly on the shoulders and back, and also have a certain protective effect on the spine. In addition, when wearing clothes of different thicknesses in different seasons, the shoulder width can also be appropriately adjusted to ensure the comfort of the backpack.

[0034] The hanging ring 6 for connecting the bag body 1 and the shoulder strap 2 can be in a square ring shape, a circular ring shape or a D-shaped shape. Preferably, the D-shaped or circular ring hanging ring 6 can make the shoulder strap 2 rotate and adjust more smoothly. The hanging ring 6 and the connecting belt 7 connected thereto are hidden and sandwiched between the bag body 1 and the first cushion block 4, which can make the backpack more beautiful.

[0035] In addition to the first pad 4, the second pad 5 and the shoulder strap 2 with adjustable shoulder width, a hard spine protection strip 12 is embedded inside the back panel 3 of the backpack. The spine protection strip 12 is vertically arranged in the middle of the back panel 3 to provide additional support to assist the user in maintaining a correct standing and walking posture and prevent bad postures such as hunchback or scoliosis caused by the weight of the backpack.

[0036] In order to facilitate the installation of the spine protection strip 12, a strip inner bag 13 and a cover 14 are provided on the inner side of the back panel 3. The strip inner bag 13 is vertically arranged in the middle of the back panel 3, and its position and shape match the spine protection strip 12. An opening is provided at the top of the strip inner bag 13 for the spine protection strip 12 to enter and exit. The spine protection strip 12 is arranged in the strip inner bag 13 and can be freely taken in and out. Velcro is provided on the cover 14 corresponding to the opening of the strip inner bag 13. After the Velcro is bonded, the cover 14 can close the top opening of the strip inner bag 13 to prevent the spine protection strip 12 from shifting or detaching. The spine protection strip 12 can be made of metal. In order to avoid being scratched by the hard edges of the spine protection strip 12 and to avoid the edges of the spine protection strip 12 damaging the bag body 1, a protective rubber cover 15 is provided on the top of the spine protection strip 12. Since the spine protection strip 12 can be detachably installed, it can be removed when it is not needed, which does not affect the normal use of the backpack and is also convenient for cleaning the backpack.

[0037] In addition, first webbing 9 is fixedly provided on both sides of the upper part of the back panel 3, and second webbing 10 corresponding to the first webbing 9 is fixedly provided on the top of the two shoulder straps 2, respectively, and the first webbing 9 and the second webbing 10 are connected to each other through a ladder buckle 11. By adjusting the length of the first webbing 9 and the second webbing 10 through the ladder buckle 11, the distance between the top of the shoulder strap 2 and the bag body 1 can be adjusted, and the position of the bag body 1 can be fine-tuned up and down, so that the first pad 4 and the second pad 5 on the back panel 3 are closer to the human body, ensuring the spine protection effect, and also making the backpack more stable and not easy to swing during activities.

[0038] The two shoulder straps 2 are also slidably connected with sliding clips 16, and the sliding direction of the sliding clips 16 is close to the length direction of the shoulder straps 2. The sliding clips 16 on the two sets of shoulder straps 2 are fixedly connected with the third webbing 17. The third webbing 17 connected to the two shoulder straps 2 are connected to each other through buckles 18. By sliding and changing the positions of the sliding clips 16 on both sides, the third webbing 17 can be adjusted to the front chest, waist and abdomen position. At the same time, after adjusting the length of the third webbing 17 on both sides by the buckles 18 to adapt to different body shapes, the weight of the backpack can be partially transferred to the chest and waist, and the backpack can be fixed more tightly on the body, reducing the shaking during travel, and also improving the overall stability, so that the user can move more freely.

[0039] In summary, the backpack has excellent spine protection function, which helps the user maintain a good posture. The shoulder width of the backpack is adjustable and can be suitable for users of different body shapes. It has good stability and higher comfort when carried.
