DETAILED DESCRIPTION

[0023] The utility model is further explained below in combination with the drawings and specific embodiments.

[0024] The utility model is further explained below in combination with the drawings and specific embodiments. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , a detailed description will be given to the embodiment. The utility model relates to a backpack decompression carrying system arranged at the backpack back of the backpack main body 1, which comprises a sandwich mesh cloth layer 7, a pressure-resistant sponge block 8 and an elastic material 9 arranged in sequence; the sandwich mesh cloth layer 7 is close to the side of a user; the pressure-resistant sponge block 8 is arranged at the position of the back of the user.

[0025] The carrying system comprises an upper back-carrying part 2, a middle back-carrying part 3 and a lower back-carrying part 4; the upper back-carrying part 2 is located at the upper part of the backpack main body 1 close to the position of the back of the user, and the lower back-carrying part 4 is located at the lower part of the backpack main body 1 close to the position of the waist of the user; the edge of the sandwich mesh cloth layer 7 at the lower back-carrying part 4 is further connected with the bonding fabric layer 11 through the bonding 10.

[0026] In the embodiment, the pressure-resistant sponge block 8 is provided with the upper back-carrying part 2, and the number of the pressure-resistant sponge 8 is 2. The upper back-carrying part 2 is provided with a hollow recess 5 between the pressure-resistant sponge blocks 8 according to the back physiological arc of ergonomics, and the hollow recess 5 corresponds to the position of the spine of the user. When the backpack is carried, the hollow recess 5 forms a pressureless space, which can reduce the probability of the backpack impacting the spine when walking, so that the spine is less stressed, and the child is more upright. And the hollow recess 5 used throughout the upper back-carrying part 2 not only provides a pressureless space, but also disperses the pressure of the backpack to the back on both sides of the spine, and can also dissipate heat and ventilate.

[0027] The pressure-resistant sponge block 8 and the elastic material 9 filled between the sandwich mesh cloth 7 and the backpack back effectively disperse the pressure of the backpack on the spine and disperse the stress.

[0028] Further, the middle back-carrying part 3 is provided with an air guide groove, which increases the circulation of air in the back, better dissipates heat, and makes the child more comfortable to carry.

[0029] Further, the lower bearing part 4 is in a micro-ladder type, which can be attached to the waist, and a waist hole 5 is arranged below, which can be supported by inserting the waist to reduce the load and provide support to the waist, which can prevent the child from bending the waist.

[0030] Further, the elastic material 9 is an elastic EVA material. The compression-resistant sponge block 8 is a high-density compression-resistant sponge. When the backpack is very heavy, the sponge material is compressed under stress, and the elastic EVA material with strong hardness can still play a role in shock absorption and load reduction, and disperse the stress on the shoulders.

[0031] Further, the fabric layer 10 of the bag body uses wear-resistant fabric. The fabric layer 10 of the bag body is sewn with the sandwich mesh 7 to wrap the back filler, stabilize the bearing shape, and increase the durability.

[0032] Further, the upper part of the bearing system is also provided with a reinforcing tape 12. The width of the reinforcing tape 12 is 3.8 cm, which is used to strengthen the connection strength between the upper bearing part 2 and the backpack body 1.

[0033] Further, the bearing system also includes a U-shaped ergonomic shoulder strap 13, an adjustable chest buckle 14, and a tape 15 with scales, and the ergonomic shoulder strap 13 is connected with the tape 15 through an anti-slip buckle 16.

[0034] The above describes the preferred embodiments of the present application. It should be understood that those skilled in the art can make many modifications and changes without creative labor according to the concept of the present application. Therefore, any technical solution obtained by logical analysis, reasoning or limited experiment on the basis of the existing technology according to the concept of the present application shall be within the protection scope determined by the claims.
