Description

Technical Field

[0001] This utility model relates to the field of backpack technology, and more specifically to a load-bearing mountaineering backpack. Background Technology

[0002] Backpacks are used to carry items and are a common daily necessity. Their invention has greatly facilitated people's lives and accelerated social development. Existing backpacks come in various structural forms, including single-shoulder bags and double-shoulder bags. Single-shoulder bags have only one shoulder strap, worn across the waist, while double-shoulder bags are worn across the back. To meet people's needs, backpacks have many different functions, such as hiking backpacks and student backpacks. Hiking backpacks can hold more items than ordinary backpacks and are easier to carry. However, existing hiking backpacks still have the following drawbacks in actual use: First, existing hiking backpacks are relatively large and can carry more items, but the force distribution is uneven when carrying them. The lack of a reasonable force distribution design means that most of the force of the backpack's load falls on the shoulders, leading to shoulder strain and soreness. Second, the back and shoulders tend to sweat and become stuffy due to the close contact with the backpack, greatly reducing comfort and diminishing the practicality of hiking backpacks. In response to this, the inventor proposes a load-bearing mountaineering backpack. By setting a wide waist belt at the bottom of the backpack and a support pad on the back, the weight of the backpack is distributed to avoid excessive stress on the shoulders. At the same time, a breathable pad is also set on the back of the backpack, and breathable mesh fabric is also set on the shoulder straps, which has a good breathability when carrying the backpack, avoids stuffiness, and improves comfort.

[0003] To address the discomfort caused by constant friction between the shoulder straps and the shoulder during hiking backpack carrying due to shaking, and to ensure the stability of the shoulder straps, Chinese Patent (Authorization Announcement No.: CN216135360U) discloses a highly comfortable hiking backpack. This utility model includes a backpack body with a zipper fixedly installed at the top and a handle fixedly installed on one side of the top. Storage pouches are fixedly installed on both sides of the outer wall of the backpack body. Two connecting posts are fixedly installed on one side of the outer wall of the backpack body, and one side of the outer wall of the two connecting posts is fixedly connected to a back pad. Two fixing plates are fixedly installed on one side of the outer wall of the back pad. This utility model achieves fixed positioning of the shoulder straps and back pad by engaging the locking blocks fixedly installed on both sides of the outer wall of the fan-shaped block fixedly installed on one side of the outer wall of the fixing plate with the locking slots opened on both sides of the inner wall of the fan-shaped groove. This ensures the stability of the shoulder straps, reduces the shaking frequency between the shoulder straps and shoulders during hiking, and improves the comfort of carrying the backpack.

[0004] This solution still has some shortcomings in application. Since mountaineering backpacks typically carry many heavy items, a reasonable distribution of force is needed to reduce stress on the shoulders. Otherwise, prolonged carrying can easily cause shoulder discomfort and injury, affecting mountaineering. Furthermore, mountaineering is an outdoor activity, and the backpack needs good breathability. Otherwise, the backpack pressing tightly against the back can easily lead to stuffiness and sweating, significantly reducing carrying comfort. Therefore, the structure of mountaineering backpacks needs to be improved to overcome the aforementioned limitations, making them more suitable for the needs and more practical. Utility Model Content

[0005] The present invention discloses a load-bearing mountaineering backpack, the main purpose of which is to overcome the above-mentioned deficiencies and shortcomings of the existing technology.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A load-bearing mountaineering backpack includes a backpack body with a cavity sewn to the back side. The cavity is made of breathable mesh and has a built-in shock-absorbing PVC pad. The backpack body has shoulder straps with a hollow structure at the top. Several shock-absorbing airbags are installed on the hollow structure and connected by mesh. Widened waist belts with adjustable straps are provided on both sides of the lower rear side of the backpack body. A support pad is provided in the middle of the lower rear side of the backpack body.

[0008] Furthermore, the shock-absorbing PVC pad is in the shape of a straight plate and has several ventilation holes, and the shock-absorbing PVC pad forms a ventilation seam with the back of the backpack body.

[0009] Furthermore, the shock-absorbing airbag is hexagonal in shape and is covered with abrasion-resistant fabric.

[0010] Furthermore, the widened and weight-reducing waist belt has a built-in sponge pad, and a first plastic buckle is provided between the adjustment straps.

[0011] Furthermore, a connecting strap is provided between the shoulder straps, and the connecting strap is provided with a second plastic buckle.

[0012] Furthermore, the support pad has an arc-shaped structure and abuts against the back of the human waist.

[0013] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0014] This invention firstly incorporates shock-absorbing airbags on the upper part of the shoulder straps of the backpack body, connected by mesh fabric. This provides cushioning during carrying, reducing stress on the shoulders and preventing direct friction between the shoulders and shoulder straps that could lead to chafing and redness. The mesh fabric also allows for good breathability between the shoulder straps and shoulders, preventing stuffiness. Secondly, widened, weight-reducing waist belts are located on both sides of the back of the backpack body. These waist belts contain built-in sponges, which, when tightened, bear part of the backpack's weight, reducing stress on the shoulder straps. Simultaneously, the middle section of the back of the backpack... The backpack features a support pad that, when carried, abuts against the middle of the back of the waist, forming a triangular structure with the shoulder straps on both sides, further reducing shoulder stress and improving stability. Finally, a shock-absorbing PVC pad is located on the back of the backpack body. This pad forms a breathable seam with ventilation holes, preventing the backpack from pressing tightly against the back and hindering ventilation, thus effectively improving carrying comfort. This invention has a simple structure and ingenious design, effectively distributing the weight of the backpack body while ensuring ventilation and comfort, making it suitable for widespread adoption.
