[0036] The following is combined with Figure 1-6 This application is described in further detail.

[0037] The embodiment of the present application discloses a detachable storage waist belt for a backpack. Figure 1 A detachable storage waist belt for a backpack includes two waist belts 1, which are detachably connected to the bottom sides of a backpack body 11. The waist belts 1 are respectively connected to a first adjustment strap 2 and a second adjustment strap 3. The adjacent ends of the first and second adjustment straps 2 and 3 are respectively provided with a female buckle 5 and a male buckle 4, which fit together. The waist belt 1 is connected to an auxiliary cloth 6 sewn on three sides. The auxiliary cloth 6 and the waist belt 1 together form a storage compartment 61. The first and second adjustment straps 2, 3, male buckle 4, and female buckle 5 can all be placed in the storage compartment 61. This design not only effectively adjusts waist circumference but also facilitates disassembly and storage.

[0038] Reference Figure 1 and Figure 2 Auxiliary belts 12 are provided on both sides of the bottom of the bag body 11. The auxiliary belts 12 are connected to the waist belt 1 by a zipper structure 13. Through the zipper structure 13, the waist belt can be removed by the zipper when it is not needed. The first adjustment belt 2 and the second adjustment belt 3 are sewn and fixed to the waist belt 1 at one end close to the waist belt 1, and the auxiliary cloth 6 is sewn to the end of the waist belt 1 close to the bag body 11. The end of the auxiliary cloth 6 away from the bag body 11 is not sewn to the waist belt 1 to form an opening, so that the first adjustment belt 2, the second adjustment belt 3, the male buckle 4 and the female buckle 5 can be placed in the storage compartment 61 through the opening. When the buckle of the waist belt is not needed, it can be conveniently stored and placed through the storage compartment 61 to save space.

[0039] Reference Figure 3 The second adjustment strap 3 is integrated, while the first adjustment strap 2 is divided into connecting segments 21 at both ends and an elastic segment 22 in the middle. The ends of the elastic segment 22 are fixed to the connecting segments 21. The elastic segment 22 includes an adjustment cord 24, sewn with an elastic band 23. The elastic band 23 allows the elastic segment 22 to stretch or contract. When the belt is adjusted to the appropriate length and buckled, it fits snugly around the user's waist. The elastic segment 22 stretches under pressure to provide a cushioning effect, reducing pressure on the waist and abdomen, minimizing the risk of constriction around the user's waist and minimizing discomfort during use.

[0040] Reference Figure 4 and Figure 5 The male buckle 4 and the female buckle 5 are integrally formed. The male buckle 4 includes a tape adjustment portion 41, a first contact portion 42, and a locking protrusion 43. The second adjustment strap 3 is movably wound around the tape adjustment portion 41. A slot 44 is defined in the sidewall of the tape adjustment portion 41. The top surface of the first contact portion 42 is smooth. The locking protrusion 43 is fixed to the top surface of the end of the first contact portion 42 away from the slot 44. A groove 45 is defined through the side of the locking protrusion 43, and the groove 45 is arranged opposite the slot 44.

[0041] Correspondingly, the female buckle 5 includes a strap adjustment portion 51 and a second fitting portion 52. The connecting section 21 of the second adjusting strap 3 is flexibly wound around the strap adjustment portion 51. The top surface of the strap adjustment portion 51 is provided with mating pressing teeth, which can increase the friction between the connecting section 21 of the second adjusting strap 3 and the strap adjustment portion 51, helping to secure the connecting section 21 and prevent it from loosening and slipping. The female buckle 5 is provided with a through hole 53, and a ridge 55 is connected to the side wall of the female buckle 5 located at the through hole 53. An insert block 54 is fixed to the side of the female buckle 5 near the male buckle 4.

[0042] When the male buckle 4 and the female buckle 5 are in contact, the locking protrusion 43 on the male buckle 4 fits into the insertion hole 53 on the female buckle 5. Simultaneously, the insert 54 fits into the slot 44, and the protrusion 55 fits into the groove 45, thus connecting the first adjustment strap 2 and the second adjustment strap 3 and ensuring the secure connection of the belt. The belt winding adjustment portion 41 and the belt reel adjustment portion 51 allow the length of the first adjustment strap 2 and the connecting section 21 to be adjusted, thereby adjusting the size of the belt to suit different users.

[0043] The user presses down the locking protrusion 43 on the male buckle 4 with force, causing the protrusion 55 to slide and separate from the groove 45. At the same time, the locking protrusion 43 is disengaged from the insertion hole 53, and the insertion block 54 is disengaged from the slot 44, thereby realizing the separation between the male buckle 4 and the female buckle 5.

[0044] At the bottom of the first fitting part 42, an installation groove 7 is formed, and a first magnet 71 is installed in the installation groove 7. At the bottom of the second fitting part 52, a placement groove 8 is formed, and a second magnet 81 is arranged in the placement groove 8. The first magnet 71 and the second magnet 81 attract each other. By attracting the first magnet 71 of the male buckle 4 and the second magnet 81 of the female buckle 5 to each other, the connection between the male buckle 4 and the female buckle 5 is completed, further ensuring the stability of the connection between the male buckle 4 and the female buckle 5.

[0045] Referring to Figure 3 and Figure 6 , one ends of the second adjustment belt 3 and the connecting section 21 close to each other are respectively movably connected to the belt winding adjustment part 41 and the belt rolling adjustment part 51. A limit buckle 9 is also arranged on the second adjustment belt 3 and the connecting section 21. The limit buckle 9 is an integrally formed structure. The limit buckle 9 includes a limit buckle body 91 and a limit strip 92, so that the limit buckle 9 is a belt buckle with a "day" - shaped cross - section. The second adjustment belt 3 and the connecting section 21 respectively pass through the limit strip 92 and then pass out of the limit buckle body 91. The limit buckle 9 can position and lock the second adjustment belt 3 and the connecting section 21, and adjust the tension of the second adjustment belt 3 or the connecting section 21.

[0046] The implementation principle of a detachable storage waist belt for a backpack in an embodiment of the present application is as follows: By using the zipper structure 13 to connect the waist belt 1 and the bag body 11, it is convenient to disassemble and install the waist belt 1 according to needs; By arranging the first adjustment belt 2 and the second adjustment belt 3 with elastic sections 22, not only can the waist circumference be flexibly adjusted, but also good buffering performance can be provided to reduce the extrusion on the waist and abdomen; By arranging the storage bin 61, it is convenient to store the first adjustment belt 2, the second adjustment belt 3, the male buckle 4 and the female buckle 5 when the waist belt is not in use.

[0047] This specific implementation manner is only an interpretation of the present application, and it is not a limitation of the present application. Those skilled in the art can make modifications without creative contributions to this specific implementation manner according to needs after reading this specification, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.
