Description

Technical Field

[0001] The utility model relates to the field of backpacking tools, in particular to a lightweight and multifunctional backpacking tool. Background Art

[0002] Carrying on the back is a traditional human-powered mode of transportation, and it plays an important role in the development of human transportation history. Influenced by the geopolitical environment, traditional carrying tools were born in hilly and mountainous areas. There are mainly two types: backpacks and backpack frames. They play a very critical role in the transportation of materials in related areas. With the development of the times, traditional carrying tools also play a key role in outdoor work such as scientific expeditions and field marches.

[0003] However, as people's demands become higher and higher, the existing ordinary carrying tools can no longer fully meet people's requirements. First, the structure of the existing carrying tools is not scientific enough, and the body burden is heavy when carrying. Second, the existing carrying tools are generally fixed carrying tools, and their carrying position cannot be changed during carrying, and they are not flexible enough. In order to solve the above problems, it is necessary to improve the existing carrying tools. Utility Model Content

[0004] The utility model aims to provide a lightweight multifunctional carrying tool to solve the problem that the existing carrying tools have unscientific structures and are inconvenient to adjust the bearing parts according to the size of the carried objects.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A lightweight multifunctional carrying tool comprises a back strap, a waist belt, a back support mechanism and a lower movable support plate, wherein the back strap is arranged on both sides of the front of the back support mechanism, and the waist belt is arranged on the lower part of the front of the back support mechanism, and the back support mechanism comprises an upper back plate, a lower back plate and a U-shaped support rod, wherein the upper back plate and the lower back plate are connected by the U-shaped support rod, and the U-shaped support rod is a telescopic structure, and the lower movable support plate is connected to the back of the lower back plate by a foldable load-bearing structure.

[0007] First of all, the structure of the present application is reasonable. The main weight is borne by the back strap, and then a waist belt is added to reduce the pressure on the shoulders, and the weight is more reasonably distributed to the waist and hips to avoid excessive pressure on the shoulders by the back strap, leaving hidden injuries. Then, since the northern support mechanism includes an upper back plate, a lower back plate and a U-shaped support rod, this structure that is not a single plate can not only accurately bear the force, but also reduce the weight compared to a whole plate on the back, making it lighter. Finally, since the U-shaped support rod is telescopic, it is possible to adjust the position of the upper and lower back plates not only according to the height of the upper body of the person, but also according to the shape and size of the carried object. This has higher flexibility, and the lower movable support plate arranged on the back of the lower back plate can play a role of bottom support.

[0008] As a further preferred embodiment of the present invention, an upper back pad is provided between the upper part of the back strap and the upper back plate, and a lower back pad is provided between the lower part of the back strap and the lower back plate.

[0009] Higher comfort level when using.

[0010] As a further preferred embodiment of the present invention, the U-shaped support rod includes an upper plug-in portion and a lower sleeve portion, the lower portion of the upper plug-in portion is plugged into the plug-in hole at the top of the lower sleeve portion, and a screw-on positioning structure is provided at the connection between the lower sleeve portion and the upper plug-in portion.

[0011] The loosening and tightening positioning between the upper plug-in connection part and the lower sleeve connection part can be achieved through the screw-tightening positioning structure.

[0012] As a further preferred embodiment of the present invention, the foldable loading structure includes a rotatable side support rod and a rotatable bottom support, the rotatable side support rod is arranged on both sides of the lower movable support plate, the inner ends of the rotatable side support rod are rotatably connected to the back side of the lower back plate, and the maximum position to which the rotatable side support rod can be rotated is perpendicular to the lower back plate, and the rotatable bottom support is arranged close to the middle of the bottom surface of the lower movable support plate, the inner ends of the rotatable bottom support are also rotatably connected to the back side of the lower back plate, and the maximum position to which the rotatable bottom support can be rotated is also perpendicular to the lower back plate.

[0013] The provided rotating bottom support can better support the lower movable support plate.

[0014] As a further preferred embodiment of the present invention, an elastic reset connection mechanism is further provided between the rotating side support rod and the lower back plate.

[0015] It is convenient for the lower movable supporting plate to be reset.

[0016] As a further preferred embodiment of the present invention, the lower movable support plate is a telescopic support plate.

[0017] By adjusting the length of the lower movable support plate, the bottom support can be flexibly provided for large and small items being carried on the back.

[0018] As a further preference of the utility model, an anti-drop rope is also provided in the middle of the outer end of the lower movable support plate, a lock buckle is provided at the upper end of the anti-drop rope, and a lock buckle connecting buckle is provided on the back side of the upper back plate at a position opposite to the lock buckle.

[0019] It is convenient to use the anti-fall rope to restrict the back of the carried items, so that the carried items are not easy to fall from the lightweight multifunctional carrying tool.

[0020] As a further preference of the utility model, side barrier anti-drop ropes are evenly arranged on both sides of the anti-drop rope, and locking buckles are arranged on the outer ends of the side barrier anti-drop ropes, and locking buckles are arranged on both sides of the upper back plate, both sides of the lower back plate and both sides of the U-shaped support rod at positions opposite to the locking buckles.

[0021] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0022] 1. First of all, the structure of the present application is reasonable. The main weight is borne by the back strap, and then a waist belt is added to reduce the pressure on the shoulders, so that the weight is more reasonably distributed to the waist and buttocks, avoiding excessive pressure on the shoulders by the back strap and leaving hidden injuries. Then, since the northern support mechanism includes an upper back plate, a lower back plate and a U-shaped support rod, this structure that is not a single plate can not only accurately bear the force, but also reduce the weight compared to a whole plate on the back, making it lighter. Finally, since the U-shaped support rod is telescopic, it is possible to adjust the position of the upper back plate and the lower back plate not only according to the height of the upper body of the person, but also according to the shape and size of the carried object. This has higher flexibility, and the lower movable support plate arranged on the back of the lower back plate can play a role of bottom support.

[0023] 2. Higher comfort level when using.

[0024] 3. The rotating bottom support can better support the lower movable support plate.

[0025] 4. By adjusting the length of the lower movable support plate, the bottom support can be flexibly provided for large and small items being carried on the back.

[0026] 5. It is convenient to use the anti-fall rope to restrict the back of the carried items, so that the carried items are not easy to fall from the lightweight multi-functional carrying tool. BRIEF DESCRIPTION OF THE DRAWINGS
