[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 3 In the embodiment of the utility model, an anti-corrosion container bag that is easy to seal includes a bag body 1, a plurality of carrying straps 3 are fixedly connected to the top of the bag body 1, a protective pad 2 is fixedly connected to the bottom end of the bag body 1, a symmetrically distributed slide rail 4 is fixedly connected to the top of the inner end wall of the bag body 1, a symmetrically distributed slide bar 5 is slidably connected between the two slide rails 4, a handle 6 is fixedly connected to the top of the slide bar 5, and a cover cloth 7 is fixedly connected to the side walls of the two slide bars 5. A symmetrically distributed long groove is opened at the top of the side wall of the bag body 1, and the cover cloth 7 penetrates the long groove of the side wall of the bag body 1 to its outside, and the cover cloth 7 is fixedly connected to the limiting strip 8 at the bottom end wall of the outer side of the bag body 1, a connecting block 9 is fixedly connected to the side wall of one of the handles 6, a slide groove is opened at the top of the connecting block 9, a spring 10 is fixedly connected to the bottom end wall of the slide groove, and a card block 11 is fixedly connected to the top of the spring 10, and a card slot 12 is opened on the side wall of the other handle 6, and a button 13 is slidably connected to the inner wall of the top of the card slot 12.

[0020] In this embodiment: by changing the original single resin of the bag body 1 to a combination of different resin materials, and adding a fiber layer in the inner layer and a rubber protective pad 2 at the bottom, the anti-corrosion and tensile properties of the bag body 1 can be effectively improved. When this container bag is filled with materials and needs to be sealed, use both hands to pull the two handles 6 closer to each other, and the slide bar 5 and the cover cloth 7 will slide along the slide rail 4. When the two slide bars 5 fit together and the cover cloth 7 completely covers the bag mouth, the connecting block 9 contacts the card slot 12 and continues to be inserted. The top wall of the card slot 12 squeezes the card block 11 into the slide slot at the top of the connecting block 9 along the top inclined surface of the card block 11, and the spring 10 is compressed. When the connecting block 9 is completely inserted into the card slot 12, the card block 11 also moves to the bottom of the vertical circular groove of the card slot 12, and the spring 10 rebounds to push the card block 11 into the vertical circular groove, thereby achieving fixed positioning of the slide bar 5 and the cover cloth 7. When opening the bag for taking out materials, one only needs to press the button 13 downward to disengage the card block 11 from the vertical circular groove of the card slot 12, thereby releasing the limiting effect on the two slide bars 5 and the cover cloth 7. Under the gravity pull of the limiting bar 8, the two cover cloths 7 and the slide bar 5 will be pulled back to the initial position and the opening of the bag body 1 will be exposed, so that the material taking operation can be carried out.

[0021] It should be additionally explained that the slide rail 4 and the slide bar 5 are both made of rubber material and can bend and deform adaptively during the lifting process.

[0022] Please refer to Figure 1 , 3 The carrying straps 3 are arranged in pairs, and each group of carrying straps 3 is symmetrically distributed on the top of the side wall of the bag body 1.

[0023] In this embodiment, the position design of the lifting belt 3 can facilitate the staff to pull up the entire bag body 1 through the lifting belt 3 to improve the material handling efficiency.

[0024] Please refer to Figures 1 to 3 The two ends of the slide rail 4 are in contact with the two side walls of the bag body 1 , and the length of the slide rail 4 is twice the length of the cover cloth 7 .

[0025] In this embodiment, the size and position design of the slide rail 4 and the size design of the cover cloth 7 are all designed to enable the cover cloth 7 to completely cover the opening of the bag body 1 .

[0026] Please refer to Figures 2-3 The handle 6 is located at the top center of the slide bar 5 , and the connecting block 9 and the card slot 12 are respectively located at the center of the side walls of the two slide bars 5 that are close to each other.

[0027] In this embodiment: the handle 6 is located at the top center of the slide bar 5, which is convenient for pulling the slide bar 5 and the cover cloth 7 through the handle 6. The connecting block 9 and the slot 12 are located at the side wall center of the slide bar 5, on the one hand to align the two, and on the other hand to enhance the limiting effect.

[0028] Please refer to Figures 1 to 3 The length and height of the limiting strip 8 are correspondingly greater than the length and height of the long groove on the side wall of the bag body 1. The edge of the long groove on the side wall of the bag body 1 is designed with rounded corners, and the mass of the limiting strip 8 is relatively large.

[0029] In this embodiment: the size of the limiting strip 8 is larger than the size of the long groove on the side wall of the bag body 1, which can effectively limit the cover cloth 7 and prevent the cover cloth 7 from completely entering the interior of the bag body 1. The rounded corners on the edges of the long groove on the side wall of the bag body 1 are designed to prevent the cover cloth 7 from being scratched and damaged. The limiting strip 8 has a large mass and can drag the two cover cloths 7 back to the initial state when the two slide bars 5 are released from the limit to expose the opening of the bag body 1 for easy material removal.

[0030] Please refer to Figure 2 The top of the card block 11 is designed as an inclined surface, and the inclined surface faces the direction of the card slot 12.

[0031] In this embodiment, the top slope of the clamping block 11 is designed so that the clamping block 11 can be pressed into the inside of the sliding groove of the connecting block 9 along the top slope, so that the connecting block 9 can be smoothly engaged in the clamping groove 12 .

[0032] Please refer to Figure 2The slot 12 is composed of a bottom horizontal circular slot and a top vertical circular slot. The diameter of the bottom horizontal circular slot matches the diameter of the connecting block 9, and the diameter of the top vertical circular slot matches the diameter of the block 11.

[0033] In this embodiment, the design of the two horizontal and vertical circular grooves of the clamping groove 12 and the corresponding diameter size can well clamp the connecting block 9 and the clamping block 11 to firmly limit the two slide bars 5 and the cover cloth 7.

[0034] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
