DETAILED DESCRIPTION
[0023] The utility model discloses a double shoulder bag body main view structure schematic diagram.
[0024] Please refer to Figures 1-5 The utility model provides a kind of technical scheme: a load-reducing double shoulder bag with detachable cushion pad, including double shoulder bag body 1, fixed shoulder strap 2 and elastic shoulder strap 3 are fixed in the back of double shoulder bag body 1, fixed shoulder strap 2 and elastic shoulder strap 3 are connected by double shoulder bag strap adjusting buckle between, back pad 5 is arranged in the back of double shoulder bag body 1, four corners of back pad 5 are positionally fixed by corner fixing belt 4, and corner fixing belt 4 is sewn and fixed on the back of double shoulder bag body 1.
[0025] Further, corner fixing belt 4 itself does not have elasticity, and four corners of back pad 5 expose the outside of corner fixing belt 4, can stably limit the position of back pad 5, avoid the escape of back pad 5.
[0026] Further, filling layer 6 is arranged on the front side of back pad 5, back pad 5 uses elastic rubber plate to fix its shape, guarantee that back pad 5 has good tenacity, can be bent easily to be fixed in corner fixing belt 4, and the material such as high elastic sponge, wool, nylon, PP is filled in filling layer 6, to ensure that back pad 5 can provide enough buffer and comfortable feeling when being used as seat pad.
[0027] Further, filling layer 6 is arranged as convex on the front side of back pad 5, and filling layer 6 is arranged as square on the front side of back pad 5, guarantee the buffer effect of filling layer 6, improve the comfortable feeling of back pad 5.
[0028] Further, the back side of the back gusset 5 is embeddedly fixed with a male magnetic nail 9, and the back of the backpack body 1 is embeddedly fixed with a female magnetic nail 10, which ensures that the back side of the back gusset 5 and the back surface of the backpack body 1 are flat and will not affect the comfort of the user. The male magnetic nail 9 and the female magnetic nail 10 are magnetically connected in position, which ensures that the back gusset 5 can be accurately adsorbed on the backpack body 1.
