[0025] As shown in FIG. 1-5, the adjusting device for the shoulder straps of the backpack in the embodiment, by assembling the first adjusting member 100 and the second adjusting member 200 on the backpack or other backpacks, solves the complexity of use caused by the traditional buckles and magic tapes, and realizes the characteristics of low cost, convenient use and simple structure.

[0026] As shown in FIG. 1-5, in the embodiment, the adjusting device for the shoulder straps of the backpack includes a first adjusting member 100 arranged in a first direction and a second adjusting member 200 arranged in a second direction, wherein the horizontal direction is the first direction, and the vertical direction for adjustment is the second direction. The first adjusting member 100 is provided with assembling members 110 at both ends, and the second adjusting member 200 is provided with a plurality of assembling parts 210 matched with the assembling members 110. At this time, the first adjusting member 100 is arranged horizontally, the assembling members 110 are assembled with the assembling parts 210 at different positions in the second direction, and the height position of the first adjusting member 100 in the vertical direction is adjusted to realize the assembly of the first adjusting member 100 and the second adjusting member 200 at different positions in the second direction. The adjusting device in the embodiment is more firm in assembly than the magic tape sticking, and is simpler in assembly than the buckle.

[0027] In the preferred embodiment in the embodiment, the first adjusting member 100 is a rectangular flat plate, the assembling members 110 on the first adjusting member 100 are elastic elastic ropes, the elastic ropes are arranged on the left and right sides of the first adjusting member 100, one end of the left elastic rope is connected to the upper left side of the rectangular plate, the other end of the left elastic rope is connected to the lower left side of the rectangular plate, one end of the right elastic rope is connected to the upper right side of the rectangular plate, and the other end of the right elastic rope is connected to the lower right side of the rectangular plate. After the left and right elastic ropes are connected to the rectangular plate, a closed shape is formed. In order to increase the clamping force of the elastic rope in the groove 220, a sewing line is arranged on the elastic rope to form two closed loops. When the closed loop close to the first adjusting member 100 is clamped in the groove 220, the closed loop close to the first adjusting member 100 has not restored to its original state and still has a certain contraction force, which is clamped in the groove 220, so that the first adjusting member 100 can be stably at a certain height and will not change the height at will.

[0028] Of course, the assembling members 110 are not limited to elastic ropes, but can also be made of non-elastic materials such as nylon, polyester, carbon fiber and other high-toughness materials. By using such non-elastic and high-toughness materials, the load-bearing and tensile capacity of the assembling members 110 is stronger and less prone to breakage, thereby making the structural strength of the entire adjusting device higher.

[0029] In the embodiment, the second adjusting member 200 is a rectangular flat plate with grooves 220, the rectangular flat plate is symmetrically arranged on the left and right sides, and the assembly part 210 matched with the assembly part 110 on the second adjusting member 200 is a groove structure, the groove structure has a plurality of grooves 220 with the same size and equidistant distribution in the vertical direction, and the grooves 220 are used for clamping with the assembly part 110 to complete the position adjustment of the first adjusting member 100 in the vertical direction (the second direction).

[0030] Specifically, in the use state, the closed ring close to the first adjusting member 100 is clamped in one of the grooves 220 of the groove structure. When it is necessary to adjust the position of the first adjusting member 100 in the vertical direction, the closed ring away from the first adjusting member 100 is only needed to be stretched outward, so that the closed ring close to the first adjusting member 100 is disengaged from the groove 220, and is moved to the outside of the groove 220 at a corresponding height, and then the closed ring away from the first adjusting member 100 is released, so that the closed ring close to the first adjusting member 100 is clamped into the groove 220 again under the action of the elasticity, thereby completing the position change of the first adjusting member 100 in the vertical direction.

[0031] In other embodiments (not shown in the figure), the first adjusting member 100 and the assembly part 110 are detachably connected. Specifically, through holes are arranged on the top of the two sides of the first adjusting member 100 and penetrate to the side, and corresponding through hole structures are also arranged on the bottom and the side. The assembly part 110 is made of a flexible elastic rope, and the shape and size of the assembly part 110 are matched and pass through all the through holes. Since the assembly part 110 is an elastic component, its elasticity may gradually decline after a long time of frequent use, and thus needs to be replaced. Therefore, the through holes arranged on the first adjusting member 100 allow the user to easily and independently complete the replacement of the assembly part 110, thereby ensuring the continuous and effective use of the product.

[0032] In the embodiment, as shown in FIG. 5, in order to facilitate operation and adjustment, an adjusting buckle 230 for cooperating with the closed ring is arranged on the groove structure. When the position of the first adjusting member 100 is adjusted, the adjusting buckle 230 is hung with the closed ring to achieve more stable connection.

[0033] In other embodiments (not shown in the figure), the groove 220 on the groove structure can be a T-shaped groove, and the assembly part 110 has the same groove width in the vertical direction in the T-shaped groove. When the assembly part 110 is clamped into the T-shaped groove, the assembly part 110 needs to be folded and placed into the horizontal groove of the T-shaped groove. When the assembly part 110 reaches the vertical groove at the bottom of the T-shaped groove, the assembly part 110 is unfolded. The groove width in the vertical direction is greater than the groove width in the horizontal direction, and thus has a certain blocking effect on the assembly part 110, so that the assembly part 110 is better clamped in the T-shaped groove.

[0034] As shown in FIG. 1, in the embodiment, the backpack 300 comprises a shoulder strap 310 and a backpack body 320, the shoulder strap 310 is connected with the first adjusting member 100, the second adjusting member 200 is fixed on the side of the backpack body 320, and the first adjusting member 100 is connected with the backpack 300 through the second adjusting member 200. The second adjusting member 200 is arranged along the adjusting direction of the shoulder strap 310 on the backpack 300, that is, in the normal state, the shoulder strap 310 is mainly adjusted in the vertical direction, and then in use, the height of the first adjusting member 100 is adjusted, thereby realizing the adjustment of the position of the shoulder strap 310 on the backpack body 320 in the vertical direction,

[0035] In the embodiment, the shoulder strap 310 is locally connected with the backpack body 320. A carabiner is arranged on the backpack body 320, the carabiner is arranged on the top of the backpack body 320, the shoulder strap 310 is connected with the carabiner through a connecting belt, and the connecting belt mainly bears the weight of the backpack body 320.

[0036] In addition, in other embodiments (not shown in the drawings), in order to facilitate use and reduce the influence on other structures, the shoulder strap 310 can also be provided with a fitting cavity in the horizontal direction, the first adjusting member 100 is partially placed in the fitting cavity, and the fitting member 110 is exposed at both ends of the fitting cavity. For example, in a double-shoulder bag, a connecting belt can be arranged between the two shoulder straps, the first adjusting member 100 is partially placed in the connecting belt, and then the height of the first adjusting member 100 is adjusted through the connection between the fitting member 110 and the fitting part 210, so as to realize the connection of the shoulder strap 310 at different positions in the height direction of the backpack body 320.

[0037] In the embodiment, as shown in FIG. 2, in order to protect the second adjusting member 200, a fitting part 330 can be arranged on the backpack body 320 close to the shoulder strap 310, a hiding cavity is arranged at the fitting part 330, the second adjusting member 200 is partially placed in the fitting part, and the fitting part 210 is exposed. The inside of the second adjusting member 200 is hidden, and then the fitting part 210 is exposed, which facilitates the cooperation between the fitting member 110 and the fitting part 210, and improves the comfort.

[0038] In the embodiment, in order to facilitate the user to use and find the fitting member 110 and the fitting part 210, the fitting part 210 on the second adjusting member 200 is arranged in the direction away from the first adjusting member 100. Generally, the fitting part 210 is easily found on the outside of the shoulder strap, but is easily hidden by the shoulder strap on the inside, so that the second adjusting member 200 is arranged away from the shoulder strap 310 with the first adjusting member 100, which facilitates the user to find the fitting part 210 in time.

[0039] In addition, the backpack has two shoulder straps 310, and two second adjusting members 200 are arranged symmetrically on two sides of the first adjusting member 100, with the central axis of the first adjusting member 100 as the axis of symmetry, and a plurality of assembly portions 210 on the two second adjusting members 200 are arranged symmetrically and the assembly portions 210 on the two second adjusting members 200 are arranged oppositely.
