To fix the connecting block 6, firstly, the connecting block 6 is engaged into the connecting slot 5, at which point the connecting threaded rod 3 corresponds to the position of the connecting insertion hole 7. Then, by rotating the first knob 4, the connecting threaded rod 3 is inserted into the connecting insertion hole 7, thereby fixing the connecting block 6. This completes the operation of installing the connecting block 6 and its connecting components onto the backpack body 1. The top sides of the two connecting blocks 6 are fixedly connected... There are mounting plates 8, and a winding roller 9 is rotatably connected to one side of the two mounting plates 8. A second knob 10 is fixedly connected to one end of the winding roller 9. A waterproof cloth 11 is provided on the winding roller 9. Two connecting straps are fixedly connected to the end of the waterproof cloth 11. A backpack male buckle 12 is fixedly connected to one end of each connecting strap. Two backpack female buckles 13 are fixedly connected to the bottom side of the backpack body 1. When it rains, the backpack male buckle 12 can be pulled to move the waterproof cloth 11. At this time, the winding roller 9 will rotate and perform a winding operation, so that the backpack male buckle 12 moves to the bottom side of the backpack body 1 and inserts into the backpack female buckle 13. At this time, the waterproof cloth 11 is in contact with the backpack body 1, and the backpack body 1 is waterproofed. When the waterproof cloth 11 is not needed, it can be rolled up, so that the backpack body 1 can be used normally.

[0021] As an optional technical solution of this utility model, the main body 1 of the mountaineering bag includes an abrasion-resistant layer 101, a first waterproof layer 102, a main body layer 103, and a second waterproof layer 104.

CORDURA fabric is a high-performance synthetic fiber fabric known for its high strength, good waterproof performance, wear resistance and lightweight. The main body layer 103 made of CORDURA fabric gives the backpack body 1 good waterproof performance and tear resistance. The second waterproof layer 104 is made of polyurethane plastic. Polyurethane plastic can effectively prevent rainwater or splashed water from entering the interior of the backpack body 1 and keep the interior of the backpack body 1 dry.

[0027] The waterproof hiking backpack provided by this utility model works on the following principle:

[0028] When it rains, the male buckle 12 of the backpack can be pulled to move the waterproof cloth 11. At this time, the winding roller 9 will rotate and unwind, so that the male buckle 12 of the backpack moves to the bottom side of the backpack body 1 and inserts the male buckle 12 into the inside of the female buckle 13 of the backpack. At this time, the waterproof cloth 11 is in contact with the backpack body 1, and waterproofing is performed on the backpack body 1.

[0029] In summary, this waterproof mountaineering backpack, through the coordinated arrangement of mounting block 2, connecting threaded rod 3, first knob 4, connecting slot 5, connecting block 6, connecting hole 7, mounting plate 8, winding roller 9, second knob 10, waterproof fabric 11, backpack male buckle 12, and backpack female buckle 13, adds an external waterproof structure to the existing mountaineering backpack. This allows for better waterproofing even if the main body 1 of the backpack is damaged, resulting in a superior waterproof effect and preventing moisture from entering the interior of the backpack body 1. Furthermore, it facilitates the installation and removal of the winding roller 9. The installation is relatively simple, and the choice of whether to install the take-up roller 9 and its connecting components can be made according to the actual needs of use. The wear-resistant layer 101 makes the wear resistance of the backpack body 1 quite good, greatly avoiding damage to the backpack body 1 due to wear or scratches. The first waterproof layer 102 and the second waterproof layer 104 make the backpack doubly waterproof, thus making the waterproof effect of the backpack better. And through the cooperation with the main body layer 103, the wear resistance and waterproof performance of the backpack body 1 are further increased, improving the practicality of the backpack.
