Abstract
Description
Technical Field
[0001] This utility model relates to the field of storage bag technology, and more specifically, to a foldable storage bag. Background Technology
[0002] Currently, there are various types of storage bags on the market for organizing items. These bags come in different shapes and materials and are widely used in homes, offices, and other places. Because they can be used to organize, store, and carry various loose items, save space, and keep items neat and tidy, storage bags are generally welcomed and loved by people.
[0003] However, existing storage bags generally have the disadvantages of being bulky and inconvenient to carry. This makes it difficult to carry them when they are no longer in use, and they also take up a lot of space, making it inconvenient to store multiple storage bags together later.
[0004] Furthermore, storage bags generally lack internal support components, resulting in poor load-bearing capacity at the bottom when the bag is open, and the stored items are prone to getting mixed up. Utility Model Content

[0031] Please see Figure 1-6 A foldable storage bag includes a bag body 1, with folded edges 2 on both sides of the bag body 1. A first fixing block 3 is provided on the outer wall of the bag body 1 on both sides, and an insertion post 4 is provided on the outer wall of each of the first fixing blocks 3. A second fixing block 5 is provided on the other side of the bag body 1, and an insertion sleeve 6 is provided on the outer wall of each of the second fixing blocks 5. Telescopic grooves 7 are provided on the outer wall of each of the insertion posts 4 on both the upper and lower sides. A spring 8 is fixed at the bottom of each telescopic groove 7, and a pin 9 is provided at the other end of each spring 8. The pins 9 are slidably installed with the telescopic grooves 7. An insertion hole 10 is provided on the outer wall of each of the insertion sleeves 6. A layer 11 is fixed on the inner wall of the bag body 1 at the bottom. Pull rings 23 are provided on the outer wall of the bag body 1 on both the front and rear sides. The upper ends of the pins 9 are inclined.
[0032] In this embodiment, a mounting bracket 12 is fixedly provided on the upper end face of the interlayer 11 and on one side. A receiving plate 13 is rotatably provided inside the mounting bracket 12. The other end of the receiving plate 13 abuts against the inner wall of the bag body 1. A first magnetic block 14 is provided on both sides of the lower end face of the receiving plate 13. A second magnetic block 15 is provided on both sides of the inner wall of the interlayer 11. The first magnetic block 14 and the second magnetic block 15 are in contact. A hand buckle 16 is provided on one side of the upper end face of the receiving plate 13.
[0033] More specifically, the user can fold the bag body 1 together using the folding edge 2, and then insert the insertion post 4 into the insertion sleeve 6 so that the insertion pin 9 enters the insertion hole 10 on the insertion sleeve 6 to fold and fix the bag body 1, thereby reducing the overall space occupied by the bag body 1 and facilitating subsequent storage and carrying. When using the bag body 1, the bag body 1 can be opened first, and then the receiving plate 13 can be rotated to make it contact the upper end surface of the interlayer 11, and then the first magnetic block 14 and the second magnetic block 15 can be made to contact, thereby fixing the receiving plate 13, so that the stored items can be placed on the upper end of the receiving plate 13, which helps to increase the load-bearing capacity of the bag body 1 and facilitates use.
[0034] Please see Figure 1 , Figure 2 and Figure 6 As an implementation method for draining accidentally leaked water: a water leakage hole 17 is provided on the upper end face of the receiving plate 13, and a water inlet hole 18 is provided on the upper end face of the interlayer 11. Multiple water inlet holes 18 and water leakage holes 17 are provided and are evenly distributed. A drain pipe 19 is fixedly provided at the lower end of the interlayer 11 and on the outer wall of the bag body 1. A threaded cap 20 is provided on one side of the drain pipe 19. A rubber plug 21 is fixedly provided on the inner wall of the threaded cap 20. The rubber plug 21 is located inside the drain pipe 19. The threaded cap 20 is threadedly connected to the outer wall of the drain pipe 19.
[0035] Specifically, when water leaks from the stored object inside the bag 1, the water will enter the space between the base layer and the bag 1 through the leak hole 17 and the inlet hole 18 to prevent the leaked water from affecting the object inside the bag 1. The water at the bottom of the interlayer 11 can be drained from the drain pipe 19 by removing the threaded cover 20 for continued use.
[0036] Please refer to Figure 1 As a further embodiment for further securing the bag body 1: Velcro 22 is fixedly provided on the inner wall of the bag body 1 and on both the front and back sides, and two sets of Velcro 22 are provided and arranged symmetrically.
[0037] Specifically, when the bag bodies 1 are attached together, the Velcro 22 will come into contact with each other to secure the bag bodies 1.
[0038] In summary, when using the overall device: the user can fold the bag body 1 together using the folding edge 2, and then insert the insertion post 4 into the insertion sleeve 6 so that the pin 9 enters the insertion hole 10 on the insertion sleeve 6 to fold and fix the bag body 1, thereby reducing the overall space occupied by the bag body 1 and facilitating subsequent storage and carrying. When using the bag body 1, the bag body 1 can be opened first, and then the receiving plate 13 can be rotated to make it contact the upper end face of the interlayer 11, and then the first magnetic block 14 can be activated. The second magnetic block 15 comes into contact with the receiving plate 13, thereby fixing the receiving plate 13 so that the stored items can be placed on the upper part of the receiving plate 13, which helps to increase the load-bearing capacity of the bag body 1. When the stored items inside the bag body 1 leak water, the water will enter the space formed between the base layer and the bag body 1 through the water leakage hole 17 and the water inlet hole 18, so as to prevent the leaked water from affecting the items in the bag body 1. Subsequently, the water at the bottom of the interlayer 11 can be drained from the drain pipe 19 by removing the threaded buckle cover 20, which is convenient for continued use.
