[0002] A waste collection bag is a specialized container for collecting various types of disposable waste. Its main function is to provide centralized storage space for disposable waste, facilitating subsequent processing and removal. Through a unique structural design, the bag's size can be flexibly adjusted to meet specific needs. It can be quickly unfolded to create a large-capacity storage space when in use, and easily folded away when not in use, effectively saving space. Suitable for various scenarios such as hospitals, laboratories, and homes, it brings convenience to waste management.
[0003] Traditional disposable waste storage bags have many shortcomings. Most bags have a fixed structure, lack flexible adjustment mechanisms, and are bulky when unfolded, making them difficult to store when not in use and taking up a lot of space, especially unsuitable for space-constrained environments. Furthermore, some bags are cumbersome to unfold and store, requiring complex assembly steps, which is not only time-consuming and labor-intensive but also makes it difficult to quickly switch between uses, failing to meet users' needs for convenient and efficient storage tools. Therefore, we propose a new type of waste storage bag. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1: Please refer to Figure 1-3 This utility model provides a technical solution: a waste collection bag, including a first plate 1, with a first groove 2 on both sides of the first plate 1. A slider 3 is movably connected to one side of the inner wall of the first groove 2. A first connecting rod 4 is connected to one side of the slider 3. A connecting piece 5 is connected to the side of the first connecting rod 4 away from the slider 3. A second plate 8 is fixedly connected to one side of the connecting piece 5. A second connecting rod 7 is provided on the outer wall of one side of the first connecting rod 4. A positioning shaft 6 is connected to the middle of one side of the first connecting rod 4. The positioning shaft 6 is fixed on the side away from the first connecting rod 4. A partition plate 10 is connected. The middle of the first connecting rod 4 and the second connecting rod 7 are movably connected to the positioning shaft 6 provided on the side wall of the partition plate 10, and the first connecting rod 4 and the second connecting rod 7 are connected in a staggered manner. A connecting groove 11 is opened on the upper outer wall of the partition plate 10. A base 9 is connected to the bottom of the partition plate 10. A storage bag body 21 is movably connected to one side of the inner wall of the first plate 1. A storage bag body 21 is connected to one side of the inner wall of the first plate 1 and the second plate 8. The storage bag body 21 is movably connected to the connecting groove 11 opened on the upper outer wall of the partition plate 10.
[0025] In this embodiment, a first plate 1 is designed, and a second plate 8 is provided on the other side of the first plate 1. The first plate 1 and the second plate 8 are connected to each other. A first groove 2 is provided on the side wall of the first plate 1, and a slider 3 is movably connected to the inner wall of the first groove 2. A first connecting rod 4 is fixedly connected to one side of the slider 3, and a connecting member 5 is movably connected to the other side of the first connecting rod 4. The connecting member 5 is fixedly connected to the outer wall of one side of the second plate 8, and a second connecting rod 7 is movably connected to the outer wall of one side of the first connecting rod 4. The second connecting rod 7 and the first connecting rod 4 are staggered and connected in the middle by a positioning shaft 6. A partition plate 10 is fixedly connected to one side of the positioning shaft 6, and a base 9 is fixedly connected to the lower end of the partition plate 10. The base 9 is made of mesh fabric and can serve as a bottom support. A connecting groove 11 is provided on the upper outer wall of the partition plate 10. A storage bag body 21 can be placed on one side of the inner wall of the first plate 1 and the second plate 8, and the upper side of the storage bag body 21 is connected to the first connecting rod 4. It can be connected to the connecting groove 11 to serve as a bag, while the base 9 can support the storage bag body 21 to prevent it from falling downwards when subjected to heavy objects, thus preventing it from being fixed in place. The divider 10 can serve as a divider, with one side for placing household waste bags and the other side for placing medical waste bags. The medical waste bags can be made of leak-proof material. Therefore, when in use, the first plate 1 can be pushed away from the second plate 8, increasing the distance between the first plate 1 and the second plate 8. At this time, the slider 3 slides longitudinally on the inner wall of the first slide groove 2, causing the first connecting rod 4 to shift and drive the second connecting rod 7 to shift at the same angle around the positioning shaft 6, so that the second connecting rod 7 and the first connecting rod 4 form an X. When the first connecting rod 4 and the second connecting rod 7 unfold, the divider 10 shifts downwards and the base 9 unfolds, so that the divider 10 is perpendicular to the base 9, thus enabling subsequent use. Conversely, it can be used for storage.
[0026] Example 2: Please refer to Figure 1-4Two storage slots 12 are formed on one outer wall of the second plate 8. A fixing post 13 is fixedly connected to one side of the inner wall of the storage slot 12. A third connecting rod 14 is connected to each side of the fixing post 13.
