Description
Technical Field
[0001] The utility model relates to the technical field of backpacks, and in particular to a load-reducing backpack. Background Art
[0002] In modern society, backpacks have become an indispensable item in people's daily lives and are widely used in various groups such as students, office workers, and outdoor enthusiasts. Backpacks are not only convenient to carry around, but can also store a large number of items, but the problem that comes with it is that carrying a backpack with heavy items for a long time will bring significant burden and fatigue to the human body, especially the shoulders and back. Therefore, developing a backpack that can effectively reduce the load and improve the comfort of carrying has become an important topic in the field of luggage design. In response to these problems, although some load-reducing backpack products have appeared in the prior art, they still have limitations in terms of load-reducing effect, comfort and practicality. Some backpacks increase comfort by increasing the complexity of the carrying system, but this often leads to an increase in the weight of the backpack itself, a cumbersome structure that is easy to damage, and inconvenient to use. Utility Model Content
[0003] In order to overcome the problems existing in the related art, the present application provides a load-reducing backpack, which is easy to use, easy to operate, has good stability, high reliability, and can switch between the load-reducing and common use states of the backpack.

The setting of the locking part achieves the purpose of freely adjusting the state of the backpack. When carrying heavier items, the locking part can be opened. The elastic part adopts a rebound decompression design to reduce the energy loss of the vertical activity of the backpack, thereby reducing the body load. This design makes the backpack float slightly under the action of elastic force, just like floating in the air, effectively reducing the sense of weight; when carrying lighter items, the locking part can be closed to release the backpack from the load-reducing state, without the effect of elastic force, and can be used as an ordinary backpack. This setting is easy to use, has good stability and high reliability, and can switch the load-reducing state at will, greatly improving the life of the backpack.
[0005] Preferably, the elastic part includes an arch unit and a connecting elastic belt connected end to end. The cooperation between the arch unit and the connecting elastic belt helps to fix and disperse the weight of the backpack, reduce the physical burden of the wearer, and the arch design makes the weight of the backpack more uniform, improving the comfort and stability of the backpack.
[0006] Preferably, the connecting elastic band is made of elastic material, the arch unit is not elastic, the length of the arch unit is greater than the length of the connecting elastic band, and the arch unit limits the elastic force range of the connecting elastic band. The connecting elastic band also has an elastic force limit range, and the service life of the connecting elastic band can be increased by limiting the elastic force range of the connecting elastic band through the arch unit.

[0037] In view of the above problems, the embodiments of the present application provide a lamp buckle device, which is easy to install, has stronger adaptability, and is suitable for mounting surfaces of various shapes and materials. It is more convenient for lamps that need to be frequently repositioned or angled, and has a high safety factor.
[0038] The technical solutions of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0039] Referring to FIG. 1, a burden-reducing backpack, the backpack body includes a back panel and straps. The two ends of the straps are respectively sewn to the back panel through a first connecting portion 1 and a second connecting portion 2. It is characterized in that both the first connecting portion 1 and the second connecting portion 2 are provided with structures for reducing burden through elasticity. The second connecting portion 2 includes a second webbing 4 sewn to the end of the strap and a second adjusting buckle 3 for adjusting the length of the webbing. The second webbing is provided with an elastic portion 5 and a locking portion 6 that matches the length of the elastic portion. The locking portion 6 can lock the stretching state of the elastic portion. The setting of the locking portion achieves the purpose of freely adjusting the state of the backpack. When carrying relatively heavy items, the locking portion can be opened. The elastic portion adopts a rebound decompression design, reducing the energy loss of the vertical movement of the backpack, thereby reducing the body load. This design makes the backpack float slightly under the action of elasticity, just like floating in the air, effectively reducing the sense of burden. When carrying relatively light items, the locking portion can be closed to release the backpack from the burden-reducing state. Without the action of elasticity, it can be used as an ordinary backpack. Such a setting is convenient to use, has good stability and high reliability, and can switch the burden-reducing state at will, greatly improving the service life of the backpack.
[0040] The elastic portion includes an arch-shaped unit 51 connected end to end and a connecting elastic band 52. The mutual cooperation of the arch-shaped unit and the connecting elastic band helps to fix and disperse the weight of the backpack at the same time, reducing the physical burden of the bearer. The arch-shaped design makes the weight of the backpack more uniform, improving the comfort and stability of carrying.
[0041] The connecting elastic band 52 is made of an elastic material. The arch-shaped unit 51 is not elastic. The length of the arch-shaped unit 51 is greater than the length of the connecting elastic band 52. The arch-shaped unit 51 limits the elastic range of the connecting elastic band 52. The connecting elastic band also has a limit range of elasticity. By limiting the elastic range of the connecting elastic band through the arch-shaped unit, the service life of the connecting elastic band can be improved.
[0042] The number of the arch-shaped units 51 is at least two. Multiple arch-shaped units can evenly distribute the force on the connecting elastic band, reducing the physical burden of the bearer and improving the comfort and stability of carrying. When the number of arch-shaped units is three, it is the optimal number under the coordination of uniform force and manufacturing cost.
[0043] The locking member includes a third webbing 61, one end of the third webbing 61 and the elastic part 5 are attached to the second webbing 4 by sewing, and the other end is connected by a matching snap buckle. The snap buckle connection achieves the purpose of simply and conveniently switching the load-reducing state. When the snap buckle connection is buckled, the shoulder strap is directly stressed by the third webbing, and the backpack is released from the load-reducing state and can be used as an ordinary backpack; when the snap buckle connection is unfastened, the shoulder strap is stressed by the elastic part, and the elastic part load acts downward, so that the elastic part produces a rebound decompression effect, reducing the energy loss of the vertical movement of the backpack, thereby reducing the body load.
[0044] In other embodiments, the first connection part includes a first webbing 7 and a first adjustment buckle 8 with adjustable webbing length, one end of the first adjustment buckle 8 is connected to the top edge of the back panel of the backpack by sewing, and the other end is connected to the seam 9 on the shoulder strap by sewing, the seam 9 is also sewn with an elastic member 10, and the other end of the elastic member 10 is connected to the back panel by sewing, and the first adjustment buckle 8 can switch the state of elastic connection or fixed connection of the shoulder strap by adjusting the relative length of the first webbing 7 and the elastic member 10. When the first adjustment buckle is tightened, the first webbing is used as the load-bearing object; when the first adjustment buckle is loosened, the elastic member is used as the load-bearing object. By adjusting the first adjustment buckle, the load-reducing state of the backpack can be switched at will, which is simple to operate and highly practical.
[0045] The elastic member 10 is a corrugated skirt pleated structure. The pleated design increases the surface area of the elastic member, making the backpack more stable and less likely to shake when carried, and providing better support for the wearer.
[0046] The number of the elastic members 10 is at least two, and the shoulder strap is sewn between at least two elastic members 10. Multiple force-bearing areas are provided to increase the service life of the backpack.
[0047] The shoulder strap is also provided with an arched elastic structure chest strap 11 and a mutually cooperating buckle 12. The elastic structure chest strap also plays a role in reducing the load, effectively dispersing the weight of the backpack, reducing the burden on the shoulders and back, and improving the comfort of carrying.
[0048] The back panel is provided with a mesh breathable sponge back pad, and the shoulder strap is an "S"-shaped shoulder strap with rebound sponge. The sponge itself has a certain elasticity, which can play a buffering role, reduce the impact and pressure of the backpack on the back, and help to distribute the weight of the backpack more evenly, thereby reducing the burden on the shoulders and back. The "S"-shaped shoulder strap with rebound sponge helps to distribute the weight of the backpack more evenly on the shoulders, thereby reducing the burden on the shoulder muscles and preventing soreness or damage caused by carrying for a long time.
[0049] During daily use, the combined use of the first connecting part and the second connecting part can switch among three states: 1. Without using elastic load reduction, tighten the first webbing in the first connecting part and lock the locking part of the second connecting part; the backpack can be used as an ordinary backpack without load reduction function. 2. Mild load reduction, open the elastic load reduction part of the first connecting part or the second connecting part, and the backpack realizes the mild load reduction function, which can be used when carrying some items that are not too heavy but require load reduction function usually; 3. Achieve full load reduction, loosen the first webbing in the first connecting part and open the locking part of the second connecting part, and the backpack maximally realizes the elastic load reduction function, which can be used when carrying relatively heavy items.
[0050] Flexibly adjust the load reduction degree according to needs, which greatly improves the practicality of backpack load reduction.
[0051] The technical solutions provided by this application include the following beneficial effects:
[0052] 1. The load reduction state of the backpack can be switched, with good stability, simple structure and high service life; 2. Flexibly adjust the load reduction degree according to needs, which is convenient to use and provides more choice space for users.
[0053] The embodiments of this application have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, practical applications or improvements to the technologies in the market, or to enable other ordinary skill in the art in the technical field to understand the disclosed embodiments.
