[0012] In a further embodiment, a pull tab is hinged on the surface of the outer frame, and the outer frame is arranged in a concave shape.

[0013] In a further solution, the zipper buckle is slidably connected to the zipper strip, and the elastic telescopic block is arranged in a convex shape.

[0014] In a further embodiment, the isolation zone is located below the zipper strip, and the length of the isolation zone is 1-3 cm.

[0015] In a further solution, two groups of the clip chain sealing strips are symmetrically distributed in the isolation area.

[0016] In a further embodiment, the flexible plastic sheet is arranged in an arc shape.

[0017] In a further embodiment, the central connection of the flexible plastic sheet is arranged between the two groups of the clip chain sealing strips.

[0018] In a further embodiment, the movable end of the flexible plastic sheet is flush with the height of the zipper sealing strip.

[0019] In a further embodiment, the zipper strip is composed of a plurality of plastic teeth and a chain passing through the plurality of plastic teeth. Beneficial Effects

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] 1. By setting up the isolation area, the clip chain sealing strip and the flexible plastic sheet, when the sealed bag is closed, the user can press to close the two sets of clip chain sealing strips above and below the isolation area, and can also appropriately squeeze the arc-shaped flexible plastic sheet to deform, so that the flexible plastic sheet limits the two sets of closed clip chain sealing strips, so that the isolation area is better sealed, and a better sealing effect can be achieved through the isolation area to protect the items in the bag from the influence of the external environment;

[0022] 2. By providing an elastic telescopic block and an outer frame, when the user needs to open or close the zipper, the user can pull the pull tab, thereby driving the outer frame and the zipper buckle connected thereto to slide along the zipper. Since both sides of the zipper buckle are connected to the outer frame through the elastic telescopic block, after the outer frame drives the zipper buckle to move to the outermost edge of the zipper, continuous pulling will squeeze the elastic telescopic block, so that the user's hand can clearly feel the elastic resistance, thereby warning the user not to pull excessively or apply excessive force, thereby avoiding damage to the zipper and the sealing bag.

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0030] like Figure 1 As shown, a plastic zipper sealing bag comprises: a bag body 1 as the main body of the plastic zipper sealing bag, used to contain articles and provide a sealing function, a zipper strip 2 is installed above the outer surface of the bag body 1, and is composed of a plurality of plastic teeth and a chain, a zipper buckle 3 is located at one end of the zipper strip 2, and is slidably connected and matched with the zipper strip, and the structure of the zipper buckle 3 and the zipper strip 2 can enable it to slide smoothly, realize the closing and opening of the zipper, thereby realizing the opening and closing function of the sealing bag, and ensuring the safety and sealing of the articles in the bag.

[0031] like Figure 1-3As shown, the concave design of the outer frame 4 can fix the zipper buckle 3, avoiding excessive pulling or applying too much force when the user pulls the pull tab 6, thereby ensuring the sealing performance of the zipper and the sealing bag, and the convex design of the elastic telescopic block 5 can increase the elastic resistance, so that the user can feel obvious resistance when pulling the pull tab 6, thereby warning the user not to pull excessively or apply too much force, thereby avoiding damage to the zipper and the sealing bag, and through the connection of the outer frame 4, the zipper buckle 3 and the elastic telescopic block 5, it can be ensured that the zipper buckle 3 can slide along the zipper strip 2, while limiting its excessive movement, thereby enhancing the stability and durability of the zipper.

[0032] like Figure 1 and 4 As shown, the function of the isolation zone 7 is to isolate the zipper strip 2 from the items inside the bag body 1, thereby reducing the influence of the zipper strip 2 on the clamp chain sealing strip 8 and avoiding deformation caused by pulling or temperature changes. The length of the isolation zone 7 is 1-3cm, and the specific length can be adjusted as needed. The clamp chain sealing strip 8 is located on the upper and lower sides of the isolation zone 7 and is matched and arranged respectively, which can ensure that the two groups of clamp chain sealing strips 8 are tightly fitted when the sealed bag is closed, thereby achieving a better sealing effect. The two groups of clamp chain sealing strips 8 are symmetrically arranged with the horizontal center line of the isolation zone 7 as the center, so that the sealing effect is more uniform. The flexible plastic sheet 9 is arranged in an arc shape and is fixedly arranged on both sides of the isolation zone 7. The arc length is greater than the length of the isolation zone 7 and can be twisted and deformed appropriately. When the sealed bag is closed, the user can press to close the two groups of clamp chain sealing strips 8 above and below the isolation zone 7, and can also appropriately squeeze the arc-shaped flexible plastic sheet 9 to deform, so that the flexible plastic sheet 9 limits the two groups of closed clamp chain sealing strips 8, so that the isolation zone 7 has better sealing. The new connection point in the flexible plastic sheet 9 is set between the two groups of the clip chain sealing strips 8. Such a symmetrical arrangement makes the pressing force more uniform. The movable end of the flexible plastic sheet 9 is flush with the clip chain sealing strip 8, so that it is convenient to touch the clip chain sealing strip 8 after pressing to play a pressing role while the overall appearance does not appear bloated, which plays a role in aesthetics.

[0033] Working principle: First, when the user needs to open or close the zipper 2, the user can pull the pull tab 6, thereby driving the outer frame 4 and the zipper buckle 3 connected thereto to slide along the zipper 2, and because the two sides of the zipper buckle 3 are connected to the outer frame 4 through the elastic expansion block 5, after the outer frame 4 drives the zipper buckle 3 to move to the outermost edge of the zipper 2, continuous pulling will squeeze the elastic expansion block 5, so that the user's hand can obviously feel the elastic resistance, thereby warning the user not to pull excessively or apply excessive force, thereby avoiding damage to the zipper and the sealed bag. When the sealed bag needs to be closed, the user presses to close the two groups of clip chain sealing strips 8 above and below the isolation area 7, and can also appropriately squeeze the arc-shaped flexible plastic sheet 9 to deform, so that the flexible plastic sheet 9 limits the two groups of closed clip chain sealing strips 8, so that the isolation area 7 is better sealed, and a better sealing effect can be achieved through the isolation area 7 to protect the items in the bag from the influence of the external environment.

[0034] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
