[0001] The utility model relates to the technical field of military backpacks, in particular to a highly breathable military activity backpack with a back surface. Background Art

[0002] As the name suggests, a military activity backpack refers to a backpack carried by soldiers when conducting military activities. Compared with traditional backpacks, military activity backpacks are more adaptable to complex outdoor military activities and are one of the important equipment for soldiers to carry supplies.

[0003] The back of the existing military backpack stickers has no ventilation design, which can easily cause soldiers to sweat profusely on their backs after carrying the backpacks for a long time, and the comfort needs to be improved. Utility Model Content

[0004] The utility model aims to provide a military activity backpack with a highly breathable back surface, which can realize a highly breathable back surface and prevent soldiers from sweating heavily on their backs, and has a strong sense of comfort.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A military activity backpack with a highly breathable back surface comprises a backpack body, a back pad is provided on the back surface of the backpack body, the back pad comprises a foam block and a wrapping cloth, the wrapping cloth is wrapped around the outside of the foam block, an opening is provided at the lower edge of the wrapping cloth, and a zipper that cooperates with each other is sewn at the edge of the opening.

[0007] By adopting the above technical solution, the air permeability of the back of the backpack patch can be improved, and the back pad can also be easily disassembled and cleaned.

[0008] Furthermore, a plurality of supporting protrusions are integrally connected to the outer surface of the foam block, the supporting protrusions are hemispherical, and the plurality of supporting protrusions are arranged in a rectangular array.

[0009] By adopting the above technical solution, the entire back surface of the backpack can be effectively prevented from being attached to the soldier's back, thereby improving air permeability.

[0010] Furthermore, a third air vent is provided inside the supporting protrusion, and a plurality of first air vents and a plurality of second air vents are provided inside the foam block, and the first air vents, the second air vents, and the third air vents are interconnected.

[0011] By adopting the above technical solution, the air flow is ensured, thereby improving the air permeability of the back side of the backpack patch.

[0012] Furthermore, the first air hole and the second air hole are vertically distributed, and the third air hole is connected to the intersection of the first air hole and the second air hole.

[0013] By adopting the above technical solution, the effectiveness of air flow is ensured.

[0014] Furthermore, shoulder straps are sewn onto the back of the backpack body.

[0015] By adopting the above technical solution, it is ensured that the backpack can be effectively carried.

[0016] Furthermore, a chest strap is sewn on the outer surface of the shoulder strap, and one end of the chest strap is connected to a quick-connect connector.

[0017] By adopting the above technical solution, the chest strap can be quickly connected and fixed, thereby improving the stability of the backpack.

[0018] In summary, the beneficial technical effects of the present invention are:

[0019] The utility model can fit the back pad on the soldier's back when the backpack is carried. During the march, the backpack's own weight cooperates with the amplitude of the body swinging when walking, and the backpack will reciprocally squeeze the soldier's back, and then squeeze the foam block and the supporting protrusions. At this time, air can effectively flow through the first ventilation hole, the second ventilation hole, and the third ventilation hole. The flowing air can effectively dissipate heat from the soldier's back, avoiding that the back side of the backpack is not breathable. At the same time, the supporting protrusions and the foam block can effectively improve the softness of the back side of the backpack, which can effectively improve the comfort of carrying the backpack. When washing, the zipper can be opened to pull out the foam block from the wrapping cloth. It is convenient to use and has high practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The method of the utility model is further described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1 、 Figure 2 、 Figure 3, a military activity backpack with a highly breathable back surface, comprising a backpack body 1, a back pad 4 is provided on the back surface of the backpack body 1, the back pad 4 comprises a foam block 5 and a wrapping cloth 10, the wrapping cloth 10 is wrapped around the outside of the foam block 5, an opening is provided at the lower edge of the wrapping cloth 10, and a zipper 11 that cooperates with each other is sewn at the edge of the opening, a plurality of supporting protrusions 8 are integrally connected to the outer surface of the foam block 5, the supporting protrusions 8 are hemispherical, and the plurality of supporting protrusions 8 are arranged in a rectangular array, a third air hole 9 is provided inside the supporting protrusion 8, a plurality of first air holes 6 and a plurality of second air holes 7 are provided inside the foam block 5, the first air hole 6, the second air hole 7, and the third air hole 9 are connected to each other, the first air hole 6 and the second air hole 7 are vertically distributed, and the third air hole 9 is connected to the first air hole At the intersection of the air holes 6 and the second air holes 7, the back pad 4 can be attached to the soldier's back when carrying the backpack. During the march, the weight of the backpack and the swing of the body during walking will cause the backpack to squeeze the soldier's back reciprocally, and then squeeze the foam block 5 and the supporting protrusion 8. At this time, the air can effectively flow through the first air holes 6, the second air holes 7, and the third air holes 9. The flowing air can effectively dissipate heat from the soldier's back, avoiding the back of the backpack from being airtight. At the same time, the supporting protrusion 8 and the foam block 5 can effectively improve the softness of the back of the backpack, and can effectively improve the comfort of carrying the backpack. When washing, the zipper 11 can be opened to pull the foam block 5 out of the wrapping cloth 10. It is convenient to use and has strong practicality.

[0026] Reference Figure 1 A shoulder strap 2 is sewn on the back of the backpack body 1, and a chest strap 3 is sewn on the outer surface of the shoulder strap 2. One end of the chest strap 3 is connected to a quick-connect connector, so that the shoulder strap 2 can be used to carry the entire backpack, and the chest strap 3 is used to improve the position stability of the shoulder strap 2.

[0027] Working principle: When in use, place the materials to be carried inside the backpack body 1, and then use the shoulder straps 2 to carry the backpack body 1 on the back. At this time, the soldier's back is in contact with the back pad 4. During the march, the weight of the backpack is combined with the amplitude of the body swinging when walking, and the backpack will reciprocate to squeeze the soldier's back, and then squeeze the foam block 5 and the supporting protrusion 8. At this time, the air can effectively flow in the first air vent 6, the second air vent 7, and the third air vent 9. The flowing air can effectively dissipate heat to the soldier's back, avoiding the back of the backpack from being airtight. At the same time, the supporting protrusion 8 and the foam block 5 can effectively improve the softness of the back of the backpack, which can effectively improve the comfort of carrying the backpack. When cleaning, the zipper 11 can be opened to pull the foam block 5 out of the wrapping cloth 10, which is convenient to use.

[0028] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
