Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of daily necessities, in particular to a backpack quick-adjusting and assembling bearing system. BACKGROUND

[0002] Backpack is an indispensable product in people's daily life, which meets the needs of people in outdoor activities or work travel. The convenience, comfort and tolerance of people when using the backpack to bear the weight completely depend on the functional design of the backpack bearing system. A good bearing system needs to have strong bearing capacity to distribute the weight of the backpack body; needs to have a convenient adjusting device to adapt to users of different body shapes and heights; needs to have a perfect ventilation structure to dissipate the heat generated by the human body during weight-bearing exercise. At present, the backpack bearing systems used in existing technologies at home and abroad are generally composed of webbing, magic tape, plastic fasteners, metal components and other materials. For example, Chinese patent CN203555310U discloses a multifunctional adjusting mountaineering bag, and Chinese patent CN220069104U discloses a mountaineering bag with improved shoulder straps. These technical solutions have complex structures, cumbersome production processes, and need to be operated in multiple steps when adjusting, which is laborious and time-consuming. The bearing system with simple structure also has defects in bearing, ventilation and weight reduction. Therefore, there is an urgent need for a backpack bearing system that integrates bearing, adjustment, ventilation and other functions, has a reasonable structure, is convenient to use and easy to produce. SUMMARY

[0003] The present application aims to overcome the shortcomings of the prior art and provide a backpack bearing system that integrates bearing, adjustment, ventilation and other functions, has a reasonable structure, is convenient to use and easy to produce. To achieve the above-mentioned purpose, the present application adopts the following technical solutions: a backpack quick-adjusting and assembling bearing system, which comprises a core framework composed of a back frame body and an adjusting accessory. The back frame body is designed based on ergonomics, conforms to the human body back curve, and has a ventilation and air permeation groove in the middle part of the back frame, a shoulder strap adjusting and connecting hole groove in the upper part of the back frame, a waist strap disassembling and fixing hole groove in the lower part of the back frame, and a bag body disassembling and fixing hole groove around the back frame. The middle part of the adjusting accessory is designed with a connecting hole groove connected with the back frame body, and the periphery of the adjusting accessory is designed with a shoulder strap fixing hole groove combined with the backpack shoulder strap. The back frame body and the adjusting accessory are made of carbon fiber material or other materials with similar physical properties, produced by mold and integrally formed, which ensures the strong bearing support performance while reducing the weight.

[0004] The beneficial effects of the present application are: 1. High integration and powerful function: all main functions of the backpack carrying system are realized by only two components, the back frame body and the adjusting accessory, and the hole and groove structure of the back frame body integrates ventilation, support, load bearing and other functions. 2. Simple structure and easy production: the back frame body and the adjusting accessory are produced by mold, and are integrally formed, compared with the existing carrying system at home and abroad, the use of material categories is reduced by 60%, and the production efficiency is greatly improved. 3. Efficient assembly: when installing the bag body, shoulder strap and waist belt of the backpack carrying system of the present application, only the parts need to be aligned with the corresponding holes and grooves on the back frame body and tightened and fixed, and all operations can be completed within one minute. The existing backpack carrying system is composed of webbing, magic tape and metal parts, and it takes at least three minutes to complete the assembly of the bag body, shoulder strap and waist belt. Compared with the two, the assembly time of the carrying system is shortened by at least 300%, and the assembly efficiency is greatly improved. 4. Convenient and rapid carrying adjustment: when using the backpack carrying system of the present application, the user only needs to align the adjusting accessory with the corresponding hole on the back frame body, and use the push-pull two simple actions to realize the carrying adjustment, and the operation time is about 5 seconds. If the existing backpack carrying system needs to complete the carrying adjustment, it takes at least one minute. Compared with the two, the carrying adjustment time is shortened by at least 500%, and the adjustment speed is greatly improved. 5. Convenient maintenance: the components used in the quick adjusting and assembling carrying system of the backpack of the present application are designed as detachable and assemblable modules, which improves the standardization of production efficiency and also provides great convenience for after-sales and maintenance. BRIEF DESCRIPTION OF DRAWINGS Figure 1 is a three-view drawing of the back frame body of the present application. Figure 2 is a three-view drawing of the adjusting accessory of the present application. Figure 3 is a combined display drawing of the carrying system of the present application.

[0005] Explanation of reference numerals in the drawing: 1-back frame body, 11-shoulder strap adjusting continuous hole and groove, 12-waist belt dismounting and fixing hole and groove, 13-bag body dismounting and fixing hole and groove, 2-adjusting accessory, 21-back frame connecting hole and groove, 22-shoulder strap fixing hole and groove, 3-carrying system combination, 31-backpack shoulder strap, 32-backpack waist belt, 33-back frame ventilation groove.

[0006] DETAILED DESCRIPTION: The present application will be further described in detail below in combination with the drawings and specific embodiments. For example Figure 1 and Figure 2As shown, the core architecture back frame body and adjusting accessories of the present application are made of carbon fiber material or other similar materials in physical properties, combined through hole and groove design, and produced by mold, which integrates functions of ventilation, support, load bearing, etc. in one while lightening. The combination of the carrying system and the backpack is realized by aligning the structure position of the backpack back ready with the corresponding bag body disassembly and fixing hole and groove (13) on the back frame body (1), and then fixed by the reserved webbing on the backpack back, which is simple and fast in overall operation. The carrying adjustment action is completed by the mutual combination of the back frame body (1) and the adjusting accessories (2) as shown in the figure Figure 3 As shown, the shoulder strap adjusting continuous hole and groove (11) on the back frame body (1) is the main structure to realize the carrying adjustment, which can be used to adapt to users of different body shapes and heights by selecting and using different position hole and groove. The adjusting accessories (2) are fixed on the backpack shoulder strap through the shoulder strap fixing hole and groove (22), and the shoulder strap only needs to align the back frame connecting hole and groove (21) on the adjusting accessories (2) with the corresponding adjusting continuous hole and groove (11) on the back frame body (1) when adjusting, and then the carrying adjustment can be realized by two simple actions of pushing and pulling. Figure 3 As shown, the installed waist belt is connected with the back frame body (1) as a whole, so that the overall weight of the backpack can be directly transmitted to the waist belt, which can scientifically distribute the load ratio of the shoulder and waist of the user when carrying the weight.

[0007] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
