Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0031] Example 1: The present utility model solves the problem that the top of the existing packaging bag will have an opening because items need to be placed, and water will enter its interior through the opening at the top of the packaging bag, thus eroding the items inside the packaging bag, resulting in poor waterproof performance. The waterproof performance can be improved by the first sealing buckle 3 and the second sealing buckle 4. It is disclosed that:
[0032] A packaging bag body 1, with a fold 2 provided at the top of the packaging bag body 1, and a binding rope 6 is slidably connected inside the fold 2; It also includes: The packaging bag body 1 is made of an aluminum foil composite material, and a first sealing buckle 3 and a second sealing buckle 4 are fixed at the top of the packaging bag body 1, and the first sealing buckle 3 extends into the second sealing buckle 4 to form a sealing and engaging mechanism;
[0033] Reference Figures 1 to 3 , Put the item into the interior of the packaging bag body 1, and then press the packaging bag body 1 by hand, so that the packaging bag body 1 will drive the first sealing buckle 3 and the second sealing buckle 4 to fit together. After exerting force again, the first sealing buckle 3 can extend into the second sealing buckle 4 to form a seal, thereby closing the opening at the top of the packaging bag body 1, avoiding water from the opening at the top of the packaging bag body 1, and further improving the waterproof performance of the packaging bag body 1;
[0034] Example 2: The present utility model solves the problem that in the use of the existing packaging bag body 1, a buckle needs to be used to play a closing role, resulting in poor efficiency. The efficiency can be improved by the pawl 9. It is disclosed that:
[0035] A receiving block 5 is fixed at the right end of the fold 2, and a binding rope 6 passes through the interior of the receiving block 5. The left end of the binding rope 6 is attached to the outer side of the anti-sticking roller 7. The anti-sticking roller 7 is connected to the interior of the receiving block 5 through a bearing, and the outer wall of the anti-sticking roller 7 is set to be a smooth surface. The top of the binding rope 6 is attached to the inner end of the limiting roller 11. The inner end of the limiting roller 11 is rotatably connected to the fixing rod 8, and the outer wall of the limiting roller 11 is wrapped with rubber. The front and rear ends of the fixing rod 8 are fixed inside the receiving block 5, and the outer end of the fixing rod 8 is connected to a pawl 9 through a bearing. The outer end of the pawl 9 is set to be arc-shaped, and the outer end of the pawl 9 extends into the interior of the limiting roller 11 to form a one-way engaging mechanism. There is a trapezoidal opening inside the limiting roller 11. The inner end of the pawl 9 is connected to a spring 10, and the inner end of the spring 10 is connected to the interior of the fixing rod 8;
[0036] Reference Figure 1 、 Figures 4 to 6, by pulling the restraint rope 6, the restraint rope 6 can drive the pleats 2 to tighten, and then the pleats 2 can play a closing role. Then, the movement of the restraint rope 6 drives the anti-sticking roller 7 to rotate, and the movement of the restraint rope 6 also drives the limit roller 11 to rotate. As a result, the rotation of the limit roller 11 squeezes the pawl 9, and then the pawl 9 is squeezed and rotates into the inside of the fixed rod 8. Then, the rotation of the pawl 9 causes it to disengage from the engagement with the limit roller 11, and the rotation of the pawl 9 squeezes the spring 10, so that the spring 10 is compressed under force. After the restraint rope 6 moves to a position, the spring 10 can push the pawl 9 into the inside of the limit roller 11, and then the limit roller 11 can be fixed. Thus, the restraint rope 6 can be limited by the limit roller 11, and the purpose of rapid closing is achieved;
[0037] Embodiment 3: The present invention solves the problem that the limit roller 11 in Embodiment 2 cannot rotate in reverse, and the limit roller 11 can be reset by the movement of the pull rope 12, and discloses:
[0038] The inner end of the pawl 9 is connected with a pull rope 12, and the front end of the pull rope 12 extends out of the inside of the fixed rod 8 to form a sliding mechanism;
[0039] Reference Figure 1 , Figures 4 to 6 , by pulling the pull rope 12, the movement of the pull rope 12 drives the pawl 9 to rotate, and then the rotation of the pawl 9 can disengage from the engagement with the limit roller 11. Then, by pulling the pleats 2, the pleats 2 can pull the restraint rope 6 to reset, so that the top opening of the packaging bag body 1 can be exposed, thus facilitating the rapid opening of the packaging bag body 1.
[0040] Working principle: When using the waist-bundling packaging bag with a water leakage prevention structure, first, reference Figures 1 to 3 , put the items into the inside of the packaging bag body 1, and then press the packaging bag body 1 with hand, so that the packaging bag body 1 drives the first sealing buckle 3 and the second sealing buckle 4 to fit. After applying force again, the opening at the top of the packaging bag body 1 can be closed, and further improves the waterproof property of the packaging bag body 1;
[0041] Reference Figure 1 , Figures 4 to 6, by pulling the restraint rope 6, the restraint rope 6 can drive the pleats 2 to tighten, and then the pleats 2 can play a role in closing. Then, the pawl 9 is squeezed and rotates into the inside of the fixed rod 8. Then, the rotation of the pawl 9 will cause it to disengage from the engagement with the limiting roller 11, and the rotation of the pawl 9 will squeeze the spring 10. After the restraint rope 6 moves to the position, the spring 10 can push the pawl 9 into the inside of the limiting roller 11, and then the limiting roller 11 can be fixed. Thus, the restraint rope 6 can be limited by the limiting roller 11, and then the purpose of quick closing is achieved;
[0042] Reference Figure 1 , Figures 4 to 6 , by pulling the pull rope 12, the movement of the pull rope 12 drives the pawl 9 to rotate. Then, the pleats 2 are pulled, so that the pleats 2 can pull the restraint rope 6 to reset. Therefore, the top opening of the packaging bag body 1 can be exposed, so that the packaging bag body 1 can be quickly opened.
