Description

Technical Field

[0001] The utility model relates to the field of logistics, in particular to a recyclable logistics packaging bag. Background Art

[0002] Logistics bags are a type of packaging product used in the logistics process to protect goods and facilitate transportation. They are usually used in industries such as postal services, express delivery, and e-commerce. They can ensure the safety of goods during transportation, reduce losses, and improve logistics efficiency. At the same time, logistics bags have their own seals, which play a certain role in safety protection and can reduce damage and contamination of goods during the logistics process.

[0003] However, most of the existing logistics bags use disposable packaging materials, such as paper packaging, plastic packaging, nylon packaging or other polymer packaging materials. After the packaging is wrapped, it is generally necessary to use tape to seal or close it. When the packaging is removed or the tape is torn off, the packaging itself is often damaged, making it unusable, resulting in high consumption. Some materials are non-degradable materials, which pollute the environment.

[0004] In order to solve the above problems, the patent document with patent number 202020637936.6 discloses a foldable logistics box, including a box body, the box body including a front box panel and a rear box panel relatively arranged, two groups of side panel structures are arranged between the front box panel and the rear box panel, the rear box panel is connected to a cover plate, a zipper strip is arranged between the cover plate and the front box panel and the upper end surface of the two side panel structures, the zipper strip is provided with a zipper head, each group of side panel structures includes two side panels which can be folded with each other, and the two side panels are respectively foldable with the adjacent front box panel or the rear box panel, and a bottom folding structure is arranged between the front box panel, the rear box panel and the lower end surfaces of the side panel structure; the front box panel is provided with a lock body, and the zipper head is connected with a lock buckle matching the lock body.

[0005] The logistics box in the above solution is easy to fold and recycle. At the same time, the lock body can be quickly unlocked, which improves the convenience of product use and facilitates recycling and repeated use.

[0006] However, to unlock the above-mentioned logistics box, an unlocking password must be input through the setting display screen. The unlocking password input through the display screen is verified with the digital verification password stored in the main board. After verification, the main board controls the control signal to the reduction motor to complete the unlocking action, thereby realizing the unlocking function.

[0007] Since the logistics box is often affected by external forces during transportation, the display screen of the above-mentioned logistics box is easily damaged, thereby affecting the use of the logistics box.

[0008] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

The protrusion 3431 at the bottom of the first lock tongue linkage block 343 is arranged on the revolving track of the transmission rod 3421. When the transmission rod 3421 rotates to the corresponding position, the protrusion 3431 will drive the first lock tongue linkage block 343 to rotate. The rotation of the first lock tongue linkage block 343 will drive the transmission block 343 with it through the through groove 3432. The connected second lock tongue linkage block 345 moves downward, thereby releasing the side of the second lock tongue linkage block 345 and the locking block 3472 of the lock tongue 347 to form a limiting structure; the lock tongue 347 rotates with the second fixed pin 348 as a fulcrum under the action of the torsion spring 349 until the locking block 3472 at the bottom of the lock tongue 347 abuts against the top surface of the second lock tongue linkage block 345, and the limiting opening 3471 of the lock tongue 347 is connected to the zipper entrance and exit 35 at the top of the outer shell 31 to form an entrance and exit channel for the zipper head 22.
