Based on changing consumer tastes, bag materials have become more diversified, with genuine leather, PU, ​​polyester, canvas, cotton, and linen leading fashion trends. At the same time, in an era that increasingly emphasizes individuality, minimalist, retro, and cartoon styles cater to the needs of fashion-conscious individuals who want to express their individuality. Bag styles have also expanded from traditional business bags, backpacks, travel bags, wallets, and small handbags.

[0003] A folding bag, disclosed in Chinese Patent Announcement No. CN221690313U, features a main body shell with a secondary body shell inserted into one side. Handles are fixedly connected to opposite sides of both the main body shell and the secondary body shell. Five equidistant first storage slots are located at the bottom of one side of the main body shell, and five equidistant second storage slots are located at the bottom of one side of the secondary body shell. A telescopic component is stored within all five first and five second storage slots.

[0004] In the above solution, the drive shaft is rotated by turning the handle, and the drive shaft synchronously drives the threaded rod to rotate, so that the second transverse fixing plate enters the movable groove as the threaded rod rotates, and the drive assembly housing moves closer to the mother housing. This results in the following disadvantages: the bag has a complex structure when in use, and the storage space of the bag needs to be adjusted through multiple transverse fixing plates, limiting parts, threaded rods, drive shafts and other parts. Utility Model Content

[0005] The purpose of this utility model is to provide a foldable bag to solve the problem that the bag has a complex structure and requires multiple horizontal fixing plates, limiting parts, threaded rods, drive shafts and other parts to adjust the storage space of the bag during use.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a foldable bag, including a sub-shell, the sub-shell being movably disposed on the right side of a mother shell, a carrier box being fixed inside the sub-shell, a plurality of fixing grooves being provided on the front and rear sides of the outer wall of the carrier box, fixing holes being provided on the front and rear sides of the outer wall of the mother shell, fixing posts being slidably inserted into two of the fixing holes, the fixing posts being slidably inserted into the fixing grooves, a stop block being fixed to the outer end of the two fixing posts, a spring being fixed between the two stop blocks and the mother shell, and the two springs being respectively wrapped around the two fixing posts.

[0007] Preferably, the right side of the mother shell has two limiting holes, and the left side of the daughter shell has two limiting posts fixed thereon, with the two limiting posts slidably inserted into the two limiting holes respectively.

[0008] Preferably, a connecting block is fixed to the left side of each of the two stops, and a connecting groove is opened on the inner side of each of the two connecting blocks. A spring piece is fixed to the front and rear sides of the outer wall of the mother shell, and the two spring pieces are slidably inserted into the two connecting grooves.

[0009] Preferably, the inner wall of the mother shell is provided with movable grooves on the front and rear sides, and the outer wall of the carrier box is provided with rollers on the front and rear sides, and the two rollers are respectively rotatably arranged in the two movable grooves.

[0010] Preferably, a U-shaped plate is fixed to the outer side of the sub-shell and the mother shell respectively, and two rubber pads are fixed to the bottom surface of the sub-shell and the mother shell respectively.

[0011] Preferably, the outer sides of the sub-shell and the mother shell are respectively fixed with side covers.

[0012] Compared with existing technologies, a foldable bag that adopts the above technical solution has the following beneficial effects:

[0013] First, during use, the combination of fixing slots, fixing holes, fixing posts, stops and springs allows users to freely adjust the storage space of the bag according to the number of items to be stored. Moreover, the whole operation process is convenient and does not require complicated tools or steps. At the same time, it simplifies the overall structure of the bag, reduces manufacturing and maintenance costs, and improves the practicality and cost-effectiveness of the bag.

[0014] Second, during use, when the user moves the sub-shell and the carrier box, the limiting post slides into the limiting hole, effectively limiting the carrier box and preventing it from shifting during movement.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4As shown, a foldable bag includes a sub-shell 1, which is movably disposed on the right side of a mother shell 2. A carrier box 3 is fixed inside the sub-shell 1. Several fixing grooves 4 are respectively opened on the front and rear sides of the outer wall of the carrier box 3. Fixing holes 5 are respectively opened on the front and rear sides of the outer wall of the mother shell 2. Fixing posts 6 are slidably inserted into the two fixing holes 5. The fixing posts 6 are slidably inserted into the fixing grooves 4. The outer ends of the two fixing posts 6 are respectively fixed with blocks 7. Springs 8 are respectively fixed between the two blocks 7 and the mother shell 2. The two springs 8 are respectively wrapped around the two fixing posts 6.

[0023] In use, when the user reduces the storage space of the folding bag according to actual needs, simply hold the two stops 7 and pull them outwards. This will cause the fixing post 6 to move outwards, gradually moving it away from the fixing groove 4 on the outer wall of the carrying box 3. During this process, the spring 8 between the stop 7 and the mother shell 2 is stretched, generating elastic potential energy. When the fixing post 6 is completely disengaged from the fixing groove 4, the user can move the sub-shell 1 to the left. At this time, the sub-shell 1 will cause the carrying box 3 inside to move closer to the mother shell 2, thereby effectively reducing the overall storage space of the folding bag. After moving to the appropriate position, the user releases the stop 7, and the previously stretched spring 8 will quickly return to its original state. Its elastic potential energy is converted into kinetic energy, pushing the fixing post 6 to automatically reset and slide back into the corresponding fixing groove 4, completing the fixation of the carrying box 3 and the sub-shell 1. By using the combination of fixing groove 4, fixing hole 5, fixing post 6, stop block 7 and spring 8, users can freely adjust the storage space of the bag according to the number of items to be stored. Moreover, the whole operation process is convenient and does not require complicated tools or steps. At the same time, it simplifies the overall structure of the bag, reduces manufacturing and maintenance costs, and improves the practicality and cost performance of the bag.

[0024] like Figures 1-4 As shown, two limiting holes 9 are opened on the right side of the mother shell 2, and two limiting posts 10 are fixed on the left side of the daughter shell 1. The two limiting posts 10 are slidably inserted into the two limiting holes 9 respectively.

[0025] During use, when the user moves the sub-shell 1 and the carrier box 3, the limiting post 10 slides into the limiting hole 9, which can limit the carrier box 3 and effectively prevent the carrier box 3 from shifting during movement, thus improving the stability and reliability of the bag during the adjustment of storage space.

[0026] like Figures 1-4As shown, connecting blocks 11 are fixed to the left side of the two blocks 7 respectively, and connecting grooves 12 are opened on the inner side of the two connecting blocks 11 respectively. Spring pieces 13 are fixed to the front and rear sides of the outer wall of the mother shell 2 respectively. The two spring pieces 13 are slidably inserted into the two connecting grooves 12 respectively. Movable grooves 14 are opened on the front and rear sides of the inner wall of the mother shell 2 respectively. Rollers 15 are rotatably arranged on the front and rear sides of the outer wall of the bearing box 3 respectively. The two rollers 15 are rotatably arranged in the two movable grooves 14 respectively.

[0027] In use, after the user pulls the stop block 7 outward, the user only needs to gently bend the spring piece 13 towards the connecting groove 12 on the inner side of the connecting block 11, allowing the spring piece 13 to smoothly slide into the connecting groove 12. When the stop block 7 is released, the spring piece 13 will support the connecting block 11 and the stop block 7 inside the connecting groove 12, keeping the stop block 7 in the pulled-out state. This eliminates the need for the user to hold the stop block 7 continuously, providing convenience and freeing the user's hands during the process of moving the carrying box 3 to adjust the storage space, making operation easier and more comfortable. After adjustment, the user pulls the stop block 7 outward again, causing the spring piece 13 to disengage from the connecting groove 12 and return to its original position. Then, the user releases the stop block 7, and the spring 8 will automatically return the stop block 7 to its original position. The whole process is simple and efficient. When the user moves the carrying box 3, the roller 15 rolls inside the movable groove 14, which helps reduce friction, making it easier and less strenuous for the user to move the carrying box 3, thus improving the convenience of user operation.

[0028] like Figures 1-3 As shown, U-shaped plates 16 are fixed to the outer sides of the sub-shell 1 and the mother shell 2 respectively, two rubber pads 17 are fixed to the bottom surfaces of the sub-shell 1 and the mother shell 2 respectively, and side covers 18 are fixed to the outer sides of the sub-shell 1 and the mother shell 2 respectively.

[0029] During use, users can lift the sub-shell 1 and the mother shell 2 by holding the U-shaped plate 16, which facilitates the handling and movement of the bag. At the same time, when the user places the sub-shell 1 and the mother shell 2 on the ground or other flat surfaces, the rubber pad 17 can provide cushioning. The side pocket 18 allows users to conveniently store items, providing additional storage space.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
