[0038] This utility model provides, for example Figures 1-5 The minimalist portable backpack shown includes a back bag 1, a front bag 2 connected to the lower front of the back bag 1, and an anti-theft zipper between the back bag 1 and the front bag 2. Shoulder straps 3 are located on both the left and right sides of the rear of the back bag 1, and a handle 4 is located at the top of the back bag 1. The backpack can be carried on both shoulders via the two shoulder straps 3, with the back bag 1 and front bag 2 worn on the back, and can also be carried by hand via the handle 4, providing multiple carrying options. The back bag 1 and front bag 2 can be closed with the anti-theft zipper, and the two zipper pulls can be locked using the anti-theft buckle located at the top front of the back bag 1, providing anti-theft protection and enhanced security.
[0039] Preferably, the rear bag 1 has multiple small divider pockets 5 at the upper right corner of the rear inner wall, multiple large divider pockets 6 at the lower right corner of the rear inner wall, multiple webbing straps 7 on the left side of the rear inner wall, multiple mesh pockets 8 on the rear side of the lower inner wall of the front bag 2, and a document pocket 9 on the front side of the lower inner wall. A computer pocket 19 with an opening facing forward is located below the multiple mesh pockets 8 and the document pocket 9, and the computer pocket 19 is located inside the front bag 2. The backpack contains multiple small divider pockets 5, multiple large divider pockets 6, multiple webbing straps 7, and multiple mesh pockets 8 for the separate placement and securing of various inspection equipment. The backpack also contains a document pocket 9 and a computer pocket 19 for storing documents and a computer, respectively. This allows for the orderly storage of various inspection equipment and items, preventing them from colliding or being damaged inside the backpack, and ensuring the safety of the equipment and documents.
[0040] Preferably, a back airbag 10 is provided at the rear end of the back bag 1, and the back airbag 10 is located between the two shoulder straps 3. Adjustment grooves 11 are provided inside the two rear corners of the upper end of the back bag 1, and the upper ends of the two shoulder straps 3 are rotatably connected to the two adjustment grooves 11 respectively. A limiting pin 12 is fixedly connected inside the adjustment groove 11, and the limiting pin 12 passes through the inside of the shoulder strap 3 and is rotatably connected to the shoulder strap 3. Since the shoulder strap 3 can be fixed inside the adjustment groove 11 by the limiting pin 12 and rotate inside the adjustment groove 11, the two shoulder straps 3 can be adjusted according to the user's position. The backpack's position is adjusted to fit the wearer's shoulder width and thickness, and the back airbag 10 features an ergonomic design. The carrying system has been carefully adjusted so that the rear of the backpack 1 fits snugly against the back through the back airbag 10, which can distribute pressure and absorb shock. This allows the backpack to fit snugly against the back while distributing weight and reducing pressure on the shoulders and back. In addition, the backpack is made of lightweight and soft fabric with a breathable mesh design, further enhancing the comfort of carrying the backpack.
[0041] Preferably, both the small divider bag 5 and the large divider bag 6 have a shrink chamber 13 on their rear sides. The shrink chamber 13 is located inside the rear inner wall of the rear end of the rear bag 1. The upper front end of the shrink chamber 13 is connected to a limiting opening 14 and communicates with the outside through the limiting opening 14. The limiting opening 14 is located on the upper rear end of the small divider bag 5 and the large divider bag 6. Both the small divider bag 5 and the large divider bag 6 have a drawstring tube 15 inside their side walls. The left and right rear ends of the drawstring tube 15 are connected to the inside of the shrink chamber 13. A sealing cap 16 is movably connected inside the shrink chamber 13. The sealing cap 16 passes through the limiting opening 14 and covers the upper end of the small divider bag 5. The front end of the sealing cap 16 is attached to the small divider bag 5 with Velcro. On the upper outer wall of the front end of bag 5, a connecting rod 17 is fixedly connected to the rear end of the sealing cap 16, and the connecting rod 17 is slidably connected inside the shrinkage cavity 13. A shrinkage pull rope 18 is connected to the front end of the connecting rod 17, and the shrinkage pull rope 18 passes through the pull rope tube 15 and is slidably connected to the pull rope tube 15. Before the inspection equipment is placed inside the small separator bag 5 and the large separator bag 6, the small separator bag 5 and the large separator bag 6 unfold under the action of tension, opening the upper opening. At the same time as the pull rope tube 15 unfolds, it pulls the shrinkage pull rope 18 from inside the shrinkage cavity 13 back into the pull rope tube 15, and drives the rear end of the sealing cap 16 to retract into the shrinkage cavity 13, with only the front end exposed, making it easier to put the equipment in.
[0042] Preferably, after the inspection equipment is placed inside the small divider bag 5 and the large divider bag 6, the sealing cover 16 is pulled forward to pull it out from inside the shrink chamber 13, covering the upper part of the small divider bag 5 and the large divider bag 6, and then attached to the upper front end of the small divider bag 5 and the large divider bag 6 with Velcro, thereby sealing the equipment inside the small divider bag 5 and the large divider bag 6. At the same time, the sealing cover 16 pulls the shrink rope 18 from inside the rope tube 15 into the shrink chamber 13 through the connecting rod 17, so that the small divider bag 5 and the large divider bag 6 shrink under the pull of the shrink rope 18, which secures the position of the equipment and prevents the equipment from shaking inside the small divider bag 5 and the large divider bag 6, thereby improving the stability of the equipment.
[0043] Preferably, when removing the equipment from the small compartment 5 and the large compartment 6, the front end of the sealing cover 16 is opened and released. The small compartment 5 and the large compartment 6 unfold again under tension, and the sealing cover 16 is pulled back into the shrinkage chamber 13 by the connecting rod 17 and the shrink rope 18, ensuring that the upper openings of the small compartment 5 and the large compartment 6 are unobstructed. This allows users to quickly retrieve the required equipment when needed, improving ease of use. The backpack has a simple yet stylish overall design that can be matched with various outfits, making it suitable for both work and daily outings.
