[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Refer to Figures 1-3 , an embodiment provided by the present utility model: a double-layer combined flexible container bag, including an outer container bag 1, a discharge pipe 2 fixedly connected to the inside of the outer container bag 1, a pleated belt 3 fixedly connected to the outer wall of the outer container bag 1, an inner container bag 4 fixedly connected to the inside of the outer container bag 1, a reinforcement sleeve 5 fixedly connected to the inside of the inner container bag 4, a connecting plate 6 fixedly connected to the inside of the pleated belt 3, a slide plate 7 fixedly connected to the outer wall of the connecting plate 6, the outer wall of the slide plate 7 slidingly connected to the inside of the reinforcement sleeve 5, a slide sleeve 8 fixedly connected to the inside of the slide plate 7, a limit ball 9 slidingly connected to the inside of the slide sleeve 8, a limit spring 10 arranged inside the slide sleeve 8, a card slot 11 opened inside the reinforcement sleeve 5, the outer wall of the limit ball 9 slidingly connected to the inside of the card slot 11, a lifting component arranged on the outer wall of the outer container bag 1, and the lifting component is used for the whole extraction and transportation of the outer container bag 1; the lifting component includes a suspender 12, and the outer wall of the suspender 12 is fixedly connected to the outer wall of the outer container bag 1; one end of the limit spring 10 is fixedly connected to the inside of the slide sleeve 8, and the other end of the limit spring 10 is fixedly connected to the outer wall of the limit ball 9;
[0024] Specifically, when the need arises to support the outer container bag 1, by stretching the corrugated belt 3, this enables the connecting plate 6 to drive the sliding plate 7 to slide inside the reinforcement sleeve 5 through the corrugated belt 3. The reinforcement sleeve 5 can effectively support the bottom of the outer container bag 1 and the inner container bag 4 inside, thereby ensuring the stability and firmness of the overall structure. During the sliding process of the sliding plate 7, the sliding sleeve 8 and the limiting ball 9 also move inside the reinforcement sleeve 5. The limiting ball 9 continuously compresses the limiting spring 10 inside the sliding sleeve 8 until the limiting ball 9 completely slides into the card slot 11, thus enabling the container bag to be firmly supported. This not only improves its stability during transportation and storage but also significantly extends the service life of the container bag.
[0025] Refer to Figure 1 and Figure 4 , fixedly connected inside the outer container bag 1 is a top cover 13, and fixedly connected inside the top cover 13 is a feed pipe 15; fixedly connected to the outer wall of the top cover 13 are multiple male magic tapes 14, and fixedly connected to the outer wall of the feed pipe 15 is a female magic tape 16, with the male magic tape 14 and the female magic tape 16 being adhered to each other; the top cover 13 and the feed pipe 15 are in contact with each other, and slidably connected inside the feed pipe 15 is a sealing plug 17; fixedly connected to the outer wall of the sealing plug 17 is a sealing ring 18, and the outer wall of the sealing ring 18 is slidably connected inside the feed pipe 15; fixedly connected to the outer wall of the sealing plug 17 is a limiting block 19, and the outer wall of the limiting block 19 is slidably connected inside the feed pipe 15;
[0026] Specifically, when the need arises to seal the feed pipe 15, by adhering the male magic tape 14 and the female magic tape 16, the coincidence of the four suspension straps 12 is achieved. This not only facilitates the overall extraction of the outer container bag 1 but also ensures the compact arrangement of the suspension straps 12, making it convenient for carrying and operation. Fixed to the outer wall of the sealing plug 17 are the sealing ring 18 and the limiting block 19. The sealing ring 18 and the limiting block 19 can effectively seal the interface between the sealing plug 17 and the feed pipe 15. This not only prevents leakage but also maintains the integrity and safety of the material during transportation and storage. At the same time, it improves the convenience of the container bag during operation and use, ensuring its reliability and safety in various environments.
[0027] Working principle: When it is necessary to support the outer container bag 1, by stretching the corrugated belt 3, the corrugated belt 3 can drive the slide plate 7 to slide inside the reinforcement sleeve 5 through the connecting plate 6. The reinforcement sleeve 5 can support the bottom outer container bag 1 and the inner container bag 4. At the same time, the slide plate 7 drives the sliding sleeve 8 and the limit ball 9 to slide inside the reinforcement sleeve 5, so that the limit ball 9 can compress the limit spring 10 inside the sliding sleeve 8 until it slides into the card slot 11, and then the position is fixed, so as to achieve the effect of firmly supporting the container bag itself, improving the stability of the container bag and extending its service life. When it is necessary to seal the feed pipe 15, by adhering the sub-magic tape 14 to the mother-magic tape 16, the four suspenders 12 can be overlapped, which is convenient for the overall extraction of the outer container bag 1. At the same time, the outer wall of the sealing plug 17 is fixed with a sealing ring 18 and a limit block 19, so that the sealing ring 18 and the limit block 19 can fully seal between the sealing plug 17 and the feed pipe 15, so as to achieve the effect of sealing the feed pipe 15. At the same time, the four suspenders 12 can be grabbed simultaneously for convenient carrying, improving the sealing performance of the container bag.
[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
