Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to a moisture-proof packaging bag. Background Art

[0002] As we all know, packaging bags are flexible containers used for packaging, storing, and transporting items, usually made of plastic, paper, cloth, or other plastic materials. They come in different shapes and sizes and can be customized to suit various needs, such as packaging food, medicine, cosmetics, and daily necessities. They are widely used in business and personal life, providing convenient packaging solutions for products and playing an important role in marketing, helping to shape the brand image of products through printing, design, and logos.

[0003] However, traditional packaging bags usually have a fixed design and structure and cannot be flexibly adjusted to adapt to different carrying methods. They are usually designed only for hand-carrying and lack adjustable cross-strings. Therefore, technical improvements are urgently needed. Utility Model Content

[0004] The purpose of the present utility model is to solve the shortcomings existing in the prior art and to propose a moisture-proof packaging bag. When the packaging bag is in use, the two sides of the limit pad are pressed to apply force to the limit spring in the storage cavity for compression, and the telescopic connecting rod is pulled to slide in the sliding groove. When the limit pad coincides with the upper end limit hole, the limit spring releases the force to cause the limit pad to rebound, thereby limiting the telescopic connecting rod. Through the combination of the limit spring and the telescopic connecting rod, the packaging bag can be easily switched to a shoulder-carrying or hand-held state as needed, providing more carrying options and enhancing the user's flexibility.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A moisture-proof packaging bag, comprising a packaging bag body, a sealing gasket fixedly connected to one side of the upper end of the packaging bag body, a snap-fitting groove formed in the upper portion of the front end outer wall of the packaging bag body, connecting blocks fixedly connected to both sides of the upper portions of the front and rear end outer walls of the packaging bag body, a sliding sleeve fixedly connected to one side of the connecting block away from the center of the packaging bag body, and a sliding groove formed in the middle portion of the upper surface of the sliding sleeve;

[0007] A telescopic connecting rod is placed at the bottom of the sliding groove, and both sides of the outer wall of the telescopic connecting rod are fixedly connected to limit pads. A storage cavity is opened inside the limit pad, and a limit spring is fixed inside the storage cavity.

[0008] Through the above technical solution, compared with the existing packaging bags, when the packaging bag is used, the cooperation of the sealing pad and the clamping groove can effectively seal the top of the packaging bag, reduce the water or moisture from entering the interior of the packaging bag from the top, thereby improving the waterproof performance of the packaging bag. By using polyethylene material for the packaging bag body, polyethylene has good waterproof performance, which can effectively prevent moisture from penetrating into the interior of the packaging bag, protecting the internal items from the influence of the humid environment, and having high practical performance.

[0009] Furthermore, the sealing gasket is engaged with the engaging groove;

[0010] With the above technical solution, the upper end of the packaging bag body can be easily sealed by the engagement of the sealing pad with the engagement groove.

[0011] Furthermore, the upper and lower ends of both sides of the outer wall of the sliding sleeve are provided with limiting holes, and the limiting pads are respectively engaged with the limiting holes;

[0012] Through the above technical solution, the limiting pads are respectively engaged with the limiting holes, so that the telescopic connecting rod can be easily adjusted.

[0013] Furthermore, the telescopic connecting rods are all slidably connected inside the sliding groove;

[0014] With the above technical solution, the telescopic connecting rod is slidably connected inside the sliding groove, so that the length of the telescopic connecting rod can be adjusted as needed.

[0015] Furthermore, a storage slot is provided at the upper end of the packaging bag body;

[0016] Through the above technical solution, the required supplies can be stored conveniently through the storage slot.

[0017] Furthermore, the upper end of the telescopic connecting rod is fixedly connected with a cross rope;

[0018] With the technical solution, the cross rope can be used to facilitate hand-carrying or shoulder-carrying.

[0019] Furthermore, the packaging bag body is made of polyethylene material;

[0020] Through the above technical solution, the polyethylene material has good waterproof performance and can effectively prevent moisture from penetrating into the interior of the packaging bag.

[0021] The utility model has the following beneficial effects:

[0022] 1. The moisture-proof packaging bag proposed by the utility model is compared with the existing packaging bags. When using the packaging bag, the two sides of the limit pad are pressed to apply force to the limit spring in the storage cavity for compression, and the telescopic connecting rod is pulled to slide in the sliding groove. When the limit pad coincides with the upper end limit hole, the limit spring releases the force to make the limit pad rebound, thereby limiting the telescopic connecting rod. Through the combination of the limit spring and the telescopic connecting rod, the packaging bag can be easily switched to a shoulder-carrying or hand-held state as needed, providing more carrying options and enhancing the user's flexibility.

[0023] 2. The moisture-proof packaging bag proposed in the present invention, compared with the existing packaging bags, can effectively seal the top of the packaging bag through the cooperation of the sealing pad and the card slot when used, reducing the entry of water or moisture into the interior of the packaging bag from the top, thereby improving the waterproof performance of the packaging bag. The packaging bag body is made of polyethylene material, which has good waterproof performance and can effectively prevent moisture from penetrating into the interior of the packaging bag, protecting the internal items from the influence of the humid environment, and has high practical performance.
