Description
Technical Field
The utility model relates to a progressive load-reducing shoulder strap knapsack, and belongs to the technical field of backpacks.
Background
Along with the development of education industry, parents and schools pay more attention to the study of children, so that the schoolbag of the children is heavier, the shoulder is used as one of main stress positions of the backpack, the user can feel uncomfortable after carrying the heavy schoolbag, and the healthy development of the children can be influenced for a long time. Most of the current schoolbag shoulder straps are supported by a single material, but the weights of different child backpacks are different, and the single supporting material is difficult to meet the requirements of different weights for cushioning and load reducing effects and backpack comfort. Therefore, how to develop a knapsack which can realize that shoulder straps can provide good load reducing experience under different weight backups becomes the problem to be solved.
Disclosure of Invention
The utility model aims to provide a progressive burden-reducing shoulder strap knapsack, which adopts compression-resistant sponge with different bearing capacities and elastic EVA elastic materials to be overlapped, and the shoulder strap knapsack is progressive layer by layer, so that the physiological structure of the shoulder of a human body can be effectively attached, and the contact fabric between the shoulder strap and the shoulder of the knapsack is enlarged.
In order to solve the technical problems, the aim of the utility model is realized as follows:
the shoulder strap knapsack with progressive load relief according to the embodiment comprises a knapsack main body and shoulder straps arranged in pairs;
the upper end part of the shoulder strap is connected with the upper part of the backpack body, and the lower end part of the shoulder strap is connected with the lower part of the backpack body through a lower strap;
the shoulder straps comprise sandwich mesh cloth and bag body fabric layers which are sewn together, and the compression-resistant sponge blocks and the elastic materials are wrapped; the resistance to compression brocade piece is located and is close to sandwich screen cloth one side, and sets up in the shoulder position.
The above-mentioned scheme is based on and is a preferable scheme of the above-mentioned scheme: the elastic material is elastic EVA material.
The above-mentioned scheme is based on and is a preferable scheme of the above-mentioned scheme: the compression-resistant sponge block is a high-density compression-resistant sponge.
The above-mentioned scheme is based on and is a preferable scheme of the above-mentioned scheme: the package fabric layer is wear-resistant fabric.
The above-mentioned scheme is based on and is a preferable scheme of the above-mentioned scheme: the length of the lower strap is adjustable.
The beneficial effects of the utility model are as follows: according to the progressive load-reducing shoulder strap knapsack, compression-resistant sponge with different bearing capacities and elastic EVA elastic materials are adopted to be overlapped, the progressive process is carried out layer by layer, the physiological structure of the shoulder of a human body is effectively fitted, the contact fabric between the shoulder strap and the shoulder of the knapsack is enlarged, the shoulder stress is effectively dispersed, the shock absorption is reduced, the comfort level of the knapsack is better for children, and the healthy growth of the children is protected.

FIG. 1 is a schematic view of a progressive relief shoulder harness backpack according to the present utility model;
fig. 2 is a schematic structural view of the shoulder strap according to the present utility model.
The labels in the figures are illustrated below: 1-a backpack body, 2-shoulder straps; 3-lower strip; 21-sandwich mesh cloth; 22-compression-resistant sponge blocks; 23-elastic material; 24-a layer of the wrapper.
Detailed Description
The utility model will be further described with reference to the drawings and specific examples.
Examples
The present embodiment will be described in detail with reference to fig. 1 and 2. The progressive relief shoulder strap backpack according to the present embodiment comprises a backpack body 1 and shoulder straps 2 arranged in pairs.
The upper end of the shoulder strap 2 is connected to the upper part of the backpack body 1, and the lower end is connected to the lower part of the backpack body 1 via a lower strap 3. The shoulder belt 2 comprises a sandwich mesh cloth 21 and a bag body fabric layer 24 which are sewn together, and the compression-resistant sponge block 22 and the elastic material 23 are wrapped; the compression-resistant brocade block 22 is positioned at one side close to the sandwich mesh cloth 21 and is arranged at the shoulder position. The compression-resistant brocade block 22 is bonded with the elastic material 23 through a high-molecular hot melt adhesive. The elastic material 23 is adhered and fixed with the bag body fabric layer 24 through the high polymer hot melt adhesive.
The sandwich mesh cloth 21 is used as a part of the shoulder belt 2 which is contacted with a user, and the soft sandwich mesh cloth can prevent the skin of the neck and shoulder parts from being abraded in the travelling process of the backpack, so that the comfort level of the backpack is improved. The compression-resistant sponge block 22 is spaced apart from both ends of the shoulder strap 2, and a high-density compression-resistant sponge is used. When the schoolbag is stressed, the compression-resistant sponge block 22 is compressed to deform, the shoulder structure can be better attached, the stress area is increased, the pressure concentrated on the shoulder stress point is dispersed, and the shock absorption and the load reduction are realized.
Further, the elastic material 23 is an elastic EVA material. When the weight of the schoolbag is heavy, the sponge material is stressed and compressed, and the elastic EVA material with high hardness can still play a role in cushioning and reducing load and dispersing the stress of the shoulder.
Further, the bag body fabric layer 24 is a wear-resistant fabric. The bag fabric layer 24 and the sandwich mesh cloth are sewn and wrapped to wrap the shoulder strap filler, so that the shape of the shoulder strap of the schoolbag is stabilized, and the durability is improved.
Further, the length of the lower strip 3 is adjustable.
In the shoulder strap 2, the sandwich mesh cloth and the bag fabric layer wrap the filling material inside, the thickness of the filling material gradually decreases from the thickness to the thickness of the filling material, shoulder curves can be better attached, the shoulder stress area is increased, the shoulder stress is dispersed, and a better cushioning and load reducing effect is provided. The design of gradual cushioning is only carried out at the main position of the shoulder, so that the thickness of other positions of the shoulder belt is ensured not to be too thick to influence the natural swing arm in the walking process, meanwhile, the unnecessary weight is reduced, and the backpack is more comfortable.
The foregoing describes in detail preferred embodiments of the present utility model. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the utility model by one of ordinary skill in the art without undue burden. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
