[0035] Refer to Figure 1 - Figure 3, An embodiment provided by the present utility model: A sealable and moisture-proof PE composite film packaging bag, including bag 1, which is made of high-strength polyethylene material, has good toughness and durability. A sealing clip 1 is fixedly connected to the top of bag 1. Sealing clip 1 is made of a sturdy plastic material, has a certain elasticity and strength, and can tightly clamp the opening of bag 1 to prevent internal items from leaking. A rubber plug 12 is fixedly connected to one side of sealing clip 1. Rubber plug 12 is made of natural rubber material, has good sealing performance and elasticity, and can closely cooperate with the closed groove 13 inside sealing clip 4 to achieve a better sealing effect. A card slot 6 is opened inside sealing clip 1. A sealing clip 4 is fixedly connected to the top of bag 1. Sealing clip 4 is also made of a sturdy plastic material. A desiccant 15 is provided inside sealing clip 4. Desiccant 15 uses an efficient silica gel desiccant 15, which can absorb the moisture inside bag 1 and keep the internal environment dry. A closed groove 13 is opened inside sealing clip 4. The inside of closed groove 13 is slidably connected to the outer wall of rubber plug 12. A limiting groove 7 is opened inside sealing clip 4, which can limit the moving range of fixture 8 to ensure that fixture 8 can accurately insert into card slot 6. A fixing block 10 is fixedly connected to the outer wall of sealing clip 4. A pressing column 11 is slidably connected inside fixing block 10. One end of pressing column 11 is fixedly connected to fixture 8. The outer wall of fixture 8 is slidably connected inside limiting groove 7. The outer wall of fixture 8 is slidably connected inside card slot 6. A first spring 9 is sleeved on the outer wall of pressing column 11. One end of first spring 9 is fixedly connected to one side of the outer wall of fixture 8, and the other end of first spring 9 is fixedly connected to the inside of sealing clip 4. A moving component is opened inside sealing clip 1. The moving component acts on moving bag 1, so as to conveniently close bag 1 and keep it dry inside.

[0036] Specifically, when it is necessary to close the bag 1, the sealing clip one 2 and the sealing clip two 4 are combined. Since the contact surface between the fixture 8 inside the sealing clip two 4 and the card slot 6 inside the sealing clip one 2 is an inclined surface, this will push the fixture 8 to slide inside the limiting slot 7. Subsequently, the fixture 8 will drive the pressing column 11 to move inside the fixed block 10, while stretching the first spring 9. When the fixture 8 enters the inside of the card slot 6, the first spring 9 will rebound, driving the fixture 8 back to its original position, so that the fixture 8 is clamped inside the card slot 6, connecting the sealing clip one 2 and the sealing clip two 4. At the same time, this will also drive their respective rubber plugs 12 to slide into the opposite closed slots 13 inside, achieving airtightness, providing good sealing performance, effectively preventing external moisture, dust, odor, etc. from entering the bag, maintaining the stability of the internal environment, ensuring that the items inside the bag will not leak out, avoiding pollution and loss. At the same time, the internal desiccant 15 keeps the inside dry. Closing the bag mouth can prevent external moisture from entering the bag, while the desiccant 15 can absorb the moisture inside the bag, thus keeping the inside dry. A dry environment helps prevent items from getting damp, moldy, deteriorated, etc., extending the shelf life and service life of the items, and making them easier to store and transport, reducing damage and loss caused by moisture.

[0037] Refer to Figure 1 and Figure 3 , the moving component includes a groove 3, the groove 3 is opened inside the sealing clip two 4, and the outer wall of another groove 3 is opened inside the sealing clip one 2.

[0038] Specifically, through the groove 3, the sealing clip one 2 and the sealing clip two 4 can be conveniently pulled, and the bag 1 can be conveniently driven to move, making it easy and convenient to pull the sealing clip one 2 and the sealing clip two 4 without additional tools or complex operation steps.

[0039] Refer to Figure 1 , Figure 3 and Figure 4, a placement drawer 5 is slidably connected inside the second sealing clip 4. Ventilation holes 14 are provided inside the placement drawer 5. The ventilation holes 14 can not only ensure that the desiccant 15 fully exerts its moisture absorption function, but also prevent the desiccant 15 particles from leaking out. The placement drawer 5 is arranged outside the desiccant 15. A moving groove 18 is provided inside the placement drawer 5, which provides a good guide for the sliding of the limiting block 17. A sliding groove 22 is provided inside the placement drawer 5. The outer wall of the moving groove 18 is slidably connected with a limiting block 17. One side of the outer wall of the limiting block 17 is fixedly connected with a clamping block 16. The outer wall of the clamping block 16 is slidably connected inside the second sealing clip 4. The other side of the limiting block 17 is fixedly connected with a sliding column 21. The sliding column 21 is made of stainless steel material, with a smooth surface and corrosion resistance. A fixed ring 20 is fixedly connected to the outer wall of the sliding column 21. The outer wall of the fixed ring 20 is slidably connected inside the sliding groove 22. A second spring 19 is sleeved on the outer wall of the sliding column 21. One end of the second spring 19 is fixedly connected to the outer wall of the limiting block 17, and the other end of the second spring 19 is fixedly connected to the inner wall of the moving groove 18, so as to conveniently replace the internal desiccant 15 without opening the bag 1 to find and replace it.

[0040] Specifically, when it is necessary to replace the internal desiccant 15, the placement drawer 5 can be pulled. Since the clamping block 16 is designed with an inclined surface, the clamping block 16 will move inward during the pulling process, which will push the limiting block 17 to slide in the moving groove 18, and at the same time will also push the sliding column 21 to move. Then the fixed ring 20 on the outer wall of the sliding column 21 will slide in the sliding groove 22 and compress the second spring 19. In this way, the placement drawer 5 can be smoothly pulled out. After placing the desiccant 15 inside the placement drawer 5 and then pushing it back to its original position, at this time, the clamping block 16 will return to its initial position under the elastic return of the second spring 19, so as to achieve fixation and prevent the placement drawer 5 from accidentally sliding out. Through the ventilation holes 14, the inside of the packaging bag can be kept dry, so as to conveniently replace the desiccant 15. Placing the desiccant 15 inside the drawer does not occupy extra space and makes full use of the space at the bottom of the sealing clip. When the desiccant 15 absorbs saturation, just open the drawer to replace the desiccant 15. The operation is simple and convenient. At the same time, the presence of the desiccant 15 can increase the sealing performance of the sealing clip and further prevent moisture from entering.

[0041] Working principle: When it is necessary to seal the bag 1, the sealing clip one 2 and the sealing clip two 4 are combined. Since the contact surface between the fixture 8 inside the sealing clip two 4 and the card slot 6 inside the sealing clip one 2 is an inclined surface, the fixture 8 is pushed to slide inside the limiting slot 7. Then, the pressing column 11 is driven by the fixture 8 to move inside the fixed block 10, and at the same time, the first spring 9 is driven to stretch. After reaching inside the card slot 6, the fixture 8 is driven back to its original position by the rebound of the first spring 9, so that the fixture 8 is clamped inside the card slot 6 to connect the sealing clip one 2 and the sealing clip two 4. At the same time, the respective rubber plugs 12 are driven to slide into the opposite sealing grooves 13 for sealing. At the same time, the inside is kept dry by the desiccant 15 inside. When it is necessary to replace the desiccant 15, the placement drawer 5 can be pulled. Since the block 16 is an inclined surface, the block 16 moves inward, thus pushing the limiting block 17 to slide inside the moving slot 18 and pushing the sliding column 21 to move, so that the fixed ring 20 on the outer wall of the sliding column 21 slides inside the sliding slot 22, and at the same time, the second spring 19 is compressed, so as to pull out the placement drawer 5. The desiccant 15 is placed inside the placement drawer 5, and then the placement drawer 5 is pushed back, so that the block 16 is driven back to its original position for fixation by the rebound of the second spring 19 to prevent it from sliding out. Then, the inside is kept dry through the vent hole 14, so as to conveniently replace the desiccant 15.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
