Technical Field

[0001] The utility model relates to the technical field of zipper packaging bags, in particular to a zipper packaging bag with a novel lock structure. Background Art

[0002] Zipper packaging bags are sealed bags with zipper openings. Zipper bags are made of plastic and are used to produce packaging bags for various daily necessities. They are usually made of transparent or translucent polyethylene and have certain flexibility and durability. Zipper bags are tough, durable and reusable, so zipper packaging bags are gradually being widely used by people.

[0003] Based on the use of zipper packaging bags, people are generally allowed to temporarily store some parts. When using them, people usually pull the zipper first to make the top open. Then, after placing the objects, they pull the zipper in the opposite direction to close it. Therefore, the zipper can move in both directions. Therefore, if the zipper position is accidentally touched when storing or carrying, an opening is easily formed, and then the objects are easily dropped. Utility Model Content

[0004] The purpose of the utility model is to provide a zipper packaging bag with a novel locking structure to solve the problem in the above-mentioned background technology that after the objects are placed, the zipper is pulled in the opposite direction to form a closure. Therefore, the zipper can move in both directions. Therefore, if the zipper position is accidentally touched when storing or carrying, an opening is easily formed, and then the objects are easily dropped.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a zipper packaging bag with a novel locking structure, comprising a packaging bag main body, a zipper main body fixed to the top of the packaging bag main body, a zipper head connected to the outer wall of the zipper main body, a zipper ring connected to one side of the zipper head, a reserved groove is provided inside the zipper ring, an arc groove is connected to the bottom end of the reserved groove, a connecting rod is installed on one side of the packaging bag main body, a ball block is installed on one side of the connecting rod, a retaining spring is connected to the front and rear ends of the ball block, and one end of the retaining spring is connected to a limiting plate.

[0006] Preferably, the bottom end of the reserved groove is connected to the arc-shaped groove, and the inner diameter of the arc-shaped groove is larger than the outer diameter of the ball block.

[0007] Preferably, the limiting plates are symmetrically distributed about the central axis of the ball block, and the retaining springs are evenly distributed between the ball block and the limiting plates.

[0008] Preferably, one end of the retaining spring is elastically connected to the ball block, and the other end of the retaining spring is elastically connected to the limiting plate.

[0009] Preferably, a first Velcro is fixed to the back end of the interior of the packaging bag body, a second Velcro is connected to the front end of the first Velcro, and a foldable cloth is fixed to the front end of the second Velcro.

[0010] Preferably, a memory iron sheet is placed inside the foldable cloth, and the inside of the foldable cloth is filled with filling cotton.

[0011] Preferably, the first Velcro and the second Velcro are bonded to each other, and the surface areas formed between the first Velcro and the second Velcro are the same in size.

[0012] Preferably, the outer side wall of the packaging bag body is coated with a first base layer, the outer side wall of the first base layer is coated with a waterproof layer, and the outer side wall of the waterproof layer is fixed with an anti-scratch and wear-resistant layer.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the zipper packaging bag with the novel lock structure not only improves the lock connection capability, but also improves the protection capability and separation convenience of the zipper packaging bag;

[0014] (1) The zipper body is installed at the top of the packaging bag body, and the zipper body and the zipper head cooperate to form a zipper structure. After that, the zipper ring is located on the side of the zipper head after closing. Since a reserved groove is provided inside the zipper ring, and the arc groove is connected to the zipper ring, the connection and installation between the zipper ring and the ball block are completed by using a connecting rod. Therefore, after closing, the ball block passes through the position of the arc groove, and the corresponding retaining spring contracts. After the ball block passes through the arc groove, the retaining spring rebounds accordingly. At this time, the limit plate plays the purpose of blocking and limiting, thereby forming a lock limit for the zipper ring. When the zipper ring needs to be operated, the limit plate is manually pressed inward, and then the zipper ring is moved upward to pull the zipper head, thereby improving the limiting capacity of the zipper ring;

[0015] (2) The first base layer is coated on the outer side wall of the packaging bag body, and then the waterproof layer is fixed on the outside of the packaging bag body to achieve the purpose of barrier waterproofing. After the anti-scratch and wear-resistant layer is fixedly connected to the waterproof layer, it is located at the outermost layer of the packaging bag body. With the addition of the anti-scratch and wear-resistant layer, it has a certain wear-resistant protection ability, thereby better improving the overall protection ability during the working process;

[0016] (3) By installing and fixing the first Velcro at the back end of the packaging bag body, a sticky connection is formed between the packaging bag body and the first Velcro, and then the first Velcro and the second Velcro are bonded and connected, the connection and installation of the foldable cloth can be completed. Since a memory iron sheet is placed inside the foldable cloth, the foldable cloth can be folded with the addition of the memory iron sheet, so that it can separate some items, thereby improving the overall convenience.
