Problems solved by technology
[0002] At present, the straps of backpacks are fixed, and there is no movable buffer space. People carry backpacks for a long time, which makes the straps press down and tighten the human body for a long time, which is easy to cause shoulder strain, especially when people are exercising. During undulating movement, the side with high shoulders will bear the weight of the entire

Embodiment Construction
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0020] see Figure 1-4 , the present invention provides a technical solution: a load-reducing backpack with evenly distributed gravity on both shoulders, comprising a bag body 1 and two symmetrically arranged shoulder straps 2 connected to the rear side of the bag body 1, the straps 2 include a connecting webbing belt 3, an elastic elastic band 4. The first limiting webbing 5 and the second limiting webbing 6, the side of the back strap 2 away from the bag bod...

The invention relates to the technical field of knapsacks, in particular to a load-reducing knapsack capable of evenly distributing gravity on double shoulders, hard connection of a joint is changed into elastic connection through a back torsion spring structure, the weight of two connecting braids can be evenly distributed when the knapsack is carried on the back, and the lengths of two straps are respectively adjusted through reciprocating motion of the torsion spring structure, so that the load-reducing knapsack is convenient to carry. The first limiting braid limits the telescopic length of the elastic band, prevents the telescopic length from exceeding the elastic limit, guarantees the durability of the elastic band, limits the movement range of the limiting rod through the limiting cavity, and improves the safety of the user. Excessive stretching and retracting of the first torsional spring and the second torsional spring are limited, durability of the first torsional spring and the second torsional spring is guaranteed, the straps slide along the limiting grooves, the left-right width of the straps is prevented from being too large, stability is improved, the straps are more attached to the back of the human body through the S-shaped steel wire frame, the supporting force of the rear width is increased, and the device conforms to ergonomics and is more comfortable.
Description
technical field [0001] The invention relates to the technical field of knapsacks, in particular to a load-reducing knapsack with balanced weight distribution on both shoulders. Background technique [0002] At present, the straps of backpacks are fixed, and there is no movable buffer space. People carry backpacks for a long time, which makes the straps press down and tighten the human body for a long time, which is easy to cause shoulder strain, especially when people are exercising. During the undulating movement, the high side of the shoulder will bear the weight of the entire bag, and the other connecting webbing is suspended in the air and is easy to slip off. This patent solves the problem of force balance on both shoulders during exercise, because the connecting webbing is not suspended, and the connecting webbing is not easy to slip off. Moreover, the joint with the back of the human body is soft and cannot form support, resulting in discomfort. Contents of the inve...
