The extension plate 32 and the load-bearing bracket 1 are set as the sliding structure, so that the extension plate 32 is more stable when moving left and right along the inner surface of the load-bearing bracket 1, and the bottom of the extension plate 32 is equidistantly provided with a limiting groove 34, and the internal snap connection of the guide slide 33 is connected with a locking mechanism 35, and the locking mechanism 35 includes an outer shell 351, a locking spring 352, an annular connecting plate 353, a locking rod 354 and a pull ring 355, and the outer shell 351 is A locking spring 352 is fixedly installed on the inner wall, and the end of the locking spring 352 is fixedly connected to the annular connecting plate 353, the end of the locking spring 352 is fixedly connected to the bottom of the annular connecting plate 353, and the other end of the locking spring 352 is fixedly connected to the inner surface of the outer shell 351, and the annular connecting plate 353 forms an elastic structure with the outer shell 351 through the locking spring 352. By setting the annular connecting plate 353 and the outer shell 351 with an elastic structure, the annular connecting plate 353 can drive the locking rod 354 to get into the limit by the rebound force when the user releases the pull ring 355 The interior of the limiting groove 34 is fixedly connected to a locking rod 354, and the end of the locking rod 354 is snap-fitted with the interior of the limiting groove 34. The top of the outer shell 351 is connected to the bottom of the load-bearing bracket 1 by bolts, and a pull ring 355 is fixedly installed on the other end of the locking rod 354, and a waterproof backpack bag 4 is fixedly connected to the inner surface of the load-bearing bracket 1, and a shoulder strap 7 is symmetrically installed on the left side of the load-bearing bracket 1, and a sundries storage bag 8 is fixedly connected to the right side of the waterproof backpack bag 4, and a water cup placement bag 9 is symmetrically sewn on the side of the waterproof backpack bag 4.

[0024] like Figure 1 and Figure 2As shown, a waterproof backpack 4 is fixedly connected to the inner surface of the load-bearing bracket 1, and a protective component 5 is symmetrically installed inside the waterproof backpack 4, the protective component 5 includes an elastic buffer mechanism 51, a protective plate 52 and a rubber protective pad 53, and the end of the elastic buffer mechanism 51 is fixedly connected to the protective plate 52, the end of the elastic buffer mechanism 51 is fixedly connected to the side of the protective plate 52, and the other end of the elastic buffer mechanism 51 is fixedly connected to the inner surface of the waterproof backpack 4, and the protective plate 52 forms an elastic structure with the waterproof backpack 4 through the elastic buffer mechanism 51, by setting the protective plate 52 and the waterproof backpack 4 as an elastic structure, the protective plate 52 can provide good buffering protection when it is hit by an object, and a rubber protective pad 53 is embedded and installed on the other side of the protective plate 52, the sponge pad 6 is equidistantly installed on the left side of the load-bearing bracket 1, and the shoulder strap 7 is symmetrically installed on the left side of the load-bearing bracket 1.

[0025] In summary, the expandable outdoor backpack is first based on Figures 1 to 4 The structure shown in , when the user needs to store items, the user grabs the pull ring 355 and pulls it downward, so that the locking rod 354 moves out from the inside of the limiting groove 34, and then the user grabs the carrying plate 31 and pulls it to the right. At this time, the extension plate 32 moves out from the inside of the carrying bracket 1 through the sliding of the guide slide bar 33, so as to adjust the storage space of the waterproof backpack bag 4. When the storage space of the waterproof backpack bag 4 reaches the required value, the user releases the pull ring 355, so that the annular connecting plate 353 drives the locking rod 354 to be inserted into the inside of the limiting groove 34 through the rebound force of the locking spring 352, so as to achieve the purpose of locking the position of the extension plate 32, and then the user classifies the items to be carried and puts them into the waterproof backpack bag 4 and the sundries storage bag 8, so as to achieve For the purpose of classified storage, the zippers on the waterproof backpack 4 and the sundries storage bag 8 are then all pulled up, and finally the user carries the backpack on the back via the shoulder strap 7. At this time, the sponge pad 6 fits against the user's back, making it more comfortable for the user to carry. Then, as the user walks, the items inside the backpack are prone to shaking. At this time, the elastic buffer mechanism 51 and the rubber protective pad 53 cooperate with each other, so that the protective plate 52 can protect the items stored in the waterproof backpack 4. In addition, since the hard structures added to the outdoor backpack (the load-bearing bracket 1, the load-bearing plate 31, the extension plate 32, the guide slide 33, the protective plate 52) are all made of light hard materials such as light plastics (such as polyethylene plastic, polycarbonate plastic, etc.), the outdoor backpack is more durable without adding too much weight burden.
