[0017] The technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0018] Please refer to Figures 1-4 In the embodiments, the cross type load reducing backpack comprises a back width 1, the front side of the back width 1 is provided with a load reducing back plate 2, the bottom of the left and right sides of the load reducing back plate 2 is provided with a load reducing waist belt 3, the side close to the back width 1 of the load reducing back plate 2 is crossly provided with two belt extension stress belts 4, the side close to the back width 1 of the load reducing back plate 2 is fixedly installed with two fixing pieces 5, the bottom of each of the two belt extension stress belts 4 is fixedly connected with the corresponding fixing piece 5, and the top of each of the two belt extension stress belts 4 is provided with a shoulder strap 6.

[0019] The back 1 is the basic load-bearing frame of the whole backpack, and the load-reducing back plate 2 is arranged on the front side of the back 1. The load-reducing back plate 2 acts as a core hub and plays a key supporting and force transmission role. The load-reducing waist belts 3 are respectively arranged at the bottom of the left and right sides of the load-reducing back plate 2. When the user wears the backpack, the load-reducing waist belts 3 can transfer part of the weight from the shoulders to the waist to disperse the overall stress.

[0020] Two cross-shaped shoulder strap extension force belts 4 are arranged on the side of the load-reducing back plate 2 close to the back 1. In order to realize the stable connection between the shoulder strap extension force belts 4 and the load-reducing back plate 2, two fixed sheets 5 are fixedly arranged on the side of the load-reducing back plate 2 close to the back 1. The bottom of the two shoulder strap extension force belts 4 is firmly connected with the corresponding fixed sheet 5 to form a stable force bearing structure. When the shoulder straps 6 are worn on the body, the two fixed sheets 5 are the force points. The length of the shoulder straps 6 is adjusted by the grommet 7. The force points are downwardly transmitted to increase the force bearing area. The fixed sheet 5 transfers the force points to the load-reducing waist belts 3 to achieve the load-reducing effect.

[0021] Two channels with a width suitable for the shoulder straps 6 are reserved on the top of the load-reducing back plate 2. The two channels not only ensure that the shoulder straps 6 can smoothly pass through, but also limit the shoulder straps 6 to prevent the shoulder straps 6 from moving left and right.

[0022] The connecting belts 8 are arranged on the opposite sides of the two shoulder straps 6, and the first plug buckle 9 is arranged between the two connecting belts 8. When the user needs to wear the backpack more stably on the body, the two connecting belts 8 can be connected together through the first plug buckle 9 to avoid the shoulder straps 6 from slipping off during the movement. The second plug buckle 10 arranged between the two load-reducing waist belts 3 facilitates the user to quickly wear and unfasten the load-reducing waist belts 3 and also can flexibly adjust the tightness of the load-reducing waist belts 3 according to the waist circumference of the user.

[0023] By using the scientific principle of downward movement of the force points, the pressure originally concentrated on the shoulders is transmitted and dispersed through the shoulder strap extension force belts 4, the load-reducing back plate 2 and the load-reducing waist belts 3, effectively increasing the overall force bearing area. From the actual use effect, it can significantly reduce the pressure on the shoulders of the user, bringing a more relaxed and comfortable experience of carrying the backpack. Whether in daily learning, work or travel, it can show excellent performance and advantages.

[0024] In the implementation, the following steps are performed:

[0025] 1) First, the load-reducing back plate 2 of the backpack is attached to the back, and the hands are respectively inserted through the two shoulder straps 6 to place the shoulder straps 6 on the shoulders. At this time, the shoulder straps 6 will naturally hang down through the channels on the top of the load-reducing back plate 2.

[0026] 2) Then look at the two straps to extend the stress band 4 top grommet 7, according to the comfort needs of their own, through the grommet 7 adjust the length of the shoulder strap 6, the movable part of the grommet 7 is pulled up, up and down the shoulder strap 6, adjust to the appropriate length, loosen the movable part of the grommet 7, so that it is fixed shoulder strap 6, at this time, the stress point will change with the length of the shoulder strap 6 adjustment, by this way to let the stress point down, for the subsequent stress dispersion preparation;

[0027] 3) Then take two shoulder straps 6 relative to one side of the connecting band 8, put the first plug 9 butt joint, so that the two connecting band 8 is connected together;

[0028] 4) Finally, the two negative waistband 3 respectively around the body, pull to the front, find the second plug 10 between the two negative waistband 3, butt joint, according to their own waist, adjust the position of the second plug 10, so that the negative waistband 3 fit the waist.

[0029] In summary, the cross type negative backpack, through the setting of the negative back plate 2, the strap extension stress band 4 and the negative waistband 3, can effectively disperse the weight originally concentrated on the shoulder to the waist, greatly reducing the stress burden of the shoulder, the strap extension stress band 4 is arranged in a cross form and is stably connected with the negative back plate 2 through the fixing piece 5, forming a scientific stress transmission structure, so that the weight of the backpack can be more evenly distributed on the back and waist of the user, thereby improving the comfort of carrying.
