[0002] The back-carrying system can be applied to various backpacks. The existing back-carrying system usually includes two symmetrically arranged shoulder straps on the left and right and two symmetrically arranged lumbar support pieces on the left and right sides. For example, a Chinese patent publication number CN204245386U discloses an adjustable backpack lumbar support structure, which includes a backpack main body. A lumbar support structure is provided at the lower end of the back of the backpack main body. The lumbar support structure includes a lock, a lock tongue, two lumbar support pieces, two adjustment buckles and two lumbar support belts. One ends of the two lumbar support pieces are respectively fixedly connected to both sides of the lower end of the backpack main body. The other ends of the two lumbar support pieces are respectively fixedly connected to an adjustment buckle and one end of a lumbar support belt. The other ends of the two lumbar support belts are movably connected to the adjustment buckles on their corresponding lumbar support pieces. The lock and the lock tongue are respectively movably sleeved on the two lumbar support belts. The lock and the lock tongue are buckled and connected to each other. An outer pocket is provided on the side of the lumbar support piece away from the body, and an elastic protrusion is provided on the side of the lumbar support piece close to the body. The adjustment buckle is a D-ring buckle. The adjustment buckles and one end of the lumbar support belt on each lumbar support piece are arranged vertically. The back-carrying system of this backpack relies on two lumbar support buckles to lock the force on the waist of the backpack, but the upper part of the backpack is in a relaxed state, and the back-carrying system does not play a better force-bearing role. Summary of the Invention

[0017] The present utility model will be further described below with reference to the accompanying drawings of the specification.

[0018] As shown in Figure 1 , 2As shown in the figure, a multifunctional knob-adjustable back-carrying system is described. In this embodiment, a backpack is taken as an example for illustration. The back-carrying system includes two symmetrically arranged shoulder straps and two symmetrically arranged lumbar support pieces 7. The shoulder strap includes a shoulder belt 2 and an adjustment strap 5. The upper end of the shoulder belt 2 is connected to the upper part of the bag body 1. The lower end of the shoulder belt 2 is connected to one end of the adjustment strap 5, and the other end of the adjustment strap 5 is connected to the lower part of the bag body 1. The adjustment strap 5 is a webbing, and an adjustment buckle can be provided on the adjustment strap 5. A cross-body strap 3 is provided on one of the shoulder straps 2. One end of the cross-body strap 3 is a fixed end and is fixed on the shoulder strap 2, and the other end of the cross-body strap 3 is a free end and is provided with a quick-connect male buckle 10. A first cord retractor 6 is provided on one of the lumbar support pieces 7. The telescopic cord of the first cord retractor 6 is connected to a first quick-connect female buckle 8. By rotating the first cord retractor 6, the position of the first quick-connect female buckle 8 can be adjusted. The quick-connect male buckle 10 can cooperate with the first quick-connect female buckle 8. The cross-body strap 3 and the first cord retractor 6 are located on different sides. For example, when the cross-body strap 3 is provided on the left shoulder strap 2, the first cord retractor 6 is provided on the right lumbar support piece 7. After the quick-connect male buckle 10 at the free end of one cross-body strap 3 is connected to the first quick-connect female buckle 8 of the first cord retractor 6 on the other side, the tightness of the cross-body strap 3 can be adjusted by rotating the first cord retractor 6. A connecting strap 4 is provided between the shoulder strap 2 and the lumbar support piece 7. The connecting strap 4 is a webbing. One end of the connecting strap 4 is fixedly connected to the lower end of the shoulder strap 2, and the other end of the connecting strap 4 is fixedly connected to the lumbar support piece 7. One end of the adjustment strap 5 is connected to the telescopic cord of the first cord retractor 6. The connecting strap 4, the adjustment strap 5, and the lumbar support piece 7 form a triangular support structure to reduce the stress and strengthen the waist protection. A second quick-connect female buckle 9 is provided on the shoulder strap 2 where the cross-body strap 3 is located. The quick-connect male buckle 10 can cooperate with the second quick-connect female buckle 9. When the cross-body strap 3 does not need to be cross-body fixed, the free end of the cross-body strap 3 can be fixed on the shoulder strap 2. The quick-connect male buckle 10 is a magnetic male buckle, and the first quick-connect female buckle 8 and the second quick-connect female buckle 9 are magnetic female buckles, which can realize the quick connection and fixation of the free end of the cross-body strap 3.

[0019] As Figure 3 As shown in the figure, the upper end of the shoulder strap 2 is connected to one end of an elastic band 12, and the other end of the elastic band 12 is fixed. The elastic band 12 is arranged in a channel on the back of the backpack back panel. The upper end of the shoulder strap 2 extends into the channel. The combination of the shoulder strap 2 and the elastic band 12 can reduce the burden and relieve the force.

[0020] As Figure 3As shown, the upper end of the shoulder strap 2 can also be connected to the second cord retractor 11. The second cord retractor 11 is provided on the back panel of the backpack and can be stored in the groove formed by the back panel cushion. The length of the shoulder strap 2 is adjusted by the second cord retractor 11, and a scale indicating the telescopic amount is provided on the shoulder strap 2.

[0021] The first cord retractor 6 and the second cord retractor 11 can be replaced by existing technologies, such as a shoelace retractor in the prior art, or a knob buckle of BOA Company. This is not elaborated in this embodiment.

[0022] Principle of the present utility model: When it is necessary to increase the force borne by the backpack system, the male quick-connect buckle 10 at the free end of the diagonal strap 3 on one side is cooperatively connected with the first female quick-connect buckle 8 on the other side of the lumbar support piece 7. The diagonal strap 3 is tightened by the first cord retractor 6, and the diagonal strap 3 stabilizes the shoulder strap 2 and the waist belt, playing a better role in bearing force.
