[0026] This specific embodiment is a large-size packaging bag with a reinforcing rib structure, and its structural diagram is shown below. Figure 1-6 As shown, the packaging bag includes a bag body 1, with a receiving groove 2 inside the bag body 1. A sleeve 3 is fixedly connected to the top edge of the bag body 1, and a collar 4 is slidably connected inside the sleeve 3. A handle rope 5, which is made of nylon, is fixedly connected to the top of the collar 4. A snap-fit box 6 is fixedly connected to the bottom of the sleeve 3, and a positioning post 7 is slidably connected inside the snap-fit box 6. The positioning post 7 extends into the inside of the collar 4. By unfolding the bag body 1, the receiving groove 2 becomes open, and the object to be placed is placed inside the receiving groove 2. When the length of the collar 4 needs to be adjusted, the positioning post 7 is pulled out, disengaging it from the inside of the collar 4. Then, the collar 4 is pulled outward from inside the sleeve 3 to complete the length adjustment, making it suitable for different people.
[0027] In this embodiment, a rotating column 8 is rotatably connected inside the snap-fit box 6, and a placement groove 9 is opened inside the positioning column 7. A lever 10 is fixedly connected to one end of the rotating column 8 and inside the placement groove 9. A handle 11 is fixedly connected to the end of the rotating column 8 away from the lever 10. The handle 11 extends to the outside of the snap-fit box 6 and has an inclined structure design. A spring 12 is fixedly connected between the middle of the bottom of the handle 11 and the snap-fit box 6. By pressing the handle 11, the handle 11 rotates around the rotating column 8 as the center point, and then squeezes the spring 12, thereby causing the lever 10 to tilt. The lever 10 will squeeze the placement groove 9, and then drive the positioning column 7 to slide in the snap-fit box 6, so that it is disengaged from the inside of the collar 4.
[0028] In addition, in this embodiment, there are two sets of handle ropes 5. One set of handle ropes 5 is fixedly connected to a protective sleeve 13. A male buckle 14 is fixedly connected to one side of the protective sleeve 13. A female buckle 15 is fixedly connected to the bottom of the protective sleeve 13 at the position corresponding to the male buckle 14. By wrapping the other set of handle ropes 5 with the protective sleeve 13, and finally fastening the male buckle 14 and the female buckle 15, the protective sleeve 13 increases the contact area between the hand and the bag body 1, effectively preventing the goods inside the bag body 1 from being too heavy, which would cause marks when taking out the bag body 1.
[0029] Furthermore, in this embodiment, a sealing groove 16 is provided on the inner side wall of the receiving groove 2. A sealing block is fixedly connected to the other side of the inner side of the sealing groove 16 at a position corresponding to the sealing groove 16. Multiple sets of reinforcing ribs 17 are fixedly connected to the outside of the bag body 1. The reinforcing ribs 17 are high-strength fiber ropes. Through the design of the reinforcing ribs 17, the overall durability of the bag body 1 is improved, and its service life is greatly extended. When the receiving groove 2 is filled with objects, the top of the bag body 1 is gathered up, so that the sealing block is inserted into the sealing groove 16, and the bag body 1 is in a closed state.
[0030] Furthermore, in this embodiment, a barrier block 18 is fixedly connected to the bottom of the inner side of the receiving groove 2. The barrier block 18 forms a hollow groove at the bottom of the inner side of the bag body 1. A sleeve rod 19 is symmetrically fixedly connected inside the hollow groove. A sliding rod 20 is slidably connected inside the sleeve rod 19. A mounting ear 21 is fixedly connected to the outside of the sliding rod 20 and the sleeve rod 19. A driven rod 22 is rotatably connected inside the mounting ear 21. The driven rod 22 has a cross-shaped structure design. A hook spring 23 is fixedly connected to the outside of the driven rod 22. By extending the sliding rod 20 outward inside the sleeve rod 19, the two sets of driven rods 22 unfold each other and stretch the hook spring 23, thereby expanding the bottom of the bag body 1. This can be adjusted according to the amount of goods. At the same time, when the bottom is opened, the bag body 1 will have good stability when placed on the ground.
[0031] Furthermore, in this embodiment, the bag body 1 is composed of a wear-resistant layer 101, a waterproof layer 102, and a heat-insulating layer 103 from the outside to the inside. The surface of the waterproof layer 102 is provided with a conical groove 104, and the inside of the conical groove 104 is provided with an expansion ball 105. The wear-resistant layer 101 effectively extends the service life of the bag body 1, and the heat-insulating layer 103 effectively maintains the constant temperature of the objects inside the bag body 1. When the surface of the bag body 1 is exposed to liquid, the expansion ball 105 expands upon contact with water, sealing the conical groove 104 and preventing it from entering the interior of the bag body 1.
[0032] When using the device of this technical solution, the bag body 1 is unfolded, and the interior of the receiving slot 2 is then designed as an open space. The object to be placed is placed inside the receiving slot 2. When the length of the collar 4 needs to be adjusted, the handle 11 is pressed, and then the handle 11 rotates around the rotating column 8 as the center point, thereby squeezing the spring 12. This causes the lever 10 to tilt, and the lever 10 will squeeze the placement slot 9, which in turn drives the positioning column 7 to slide in the snap-fit box 6, disengaging it from the inside of the collar 4, thus completing the length adjustment to suit different people. The protective sleeve 13 is used to wrap another set of handle ropes 5, and finally the male buckle 14 and female buckle 15 are fastened. The protective sleeve 13 increases the contact area between the bag and the palm, effectively preventing the bag body 1 from being too heavy and causing marks when taking it out. The design of the reinforcing rib 17 improves the overall durability of the bag body 1. This design significantly extends the service life of the bag. When the container 2 is filled with objects, the top of the bag 1 is gathered, allowing the sealing block to be inserted into the sealing groove 16, thus sealing the bag 1. The sliding rod 20 extends outward from inside the sleeve rod 19, and then the two sets of driven rods 22 unfold and stretch the hook spring 23, expanding the bottom of the bag 1. This can be adjusted according to the amount of goods. When the bottom is open, the bag 1 also has good stability when placed on the ground. The wear-resistant layer 101 effectively extends the service life of the bag 1, and the insulation layer 103 effectively maintains a constant temperature for the objects inside the bag 1. When liquid seeps into the surface of the bag 1, the expansion ball 105 expands upon contact with water, sealing the conical groove 104 and preventing liquid from entering the interior of the bag 1. Compared with existing packaging bags, this utility model improves the overall practicality of the packaging bag through its design.
[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
