[0028] like Figures 1 to 4As shown in this specific embodiment, a waterproof and wear-resistant paper-plastic composite bag includes a bag body 1. Handles 12 are fixedly provided on both sides of the bag body 1. The bag opening 101 at the upper end of the bag body 1 is inclined. A cap 13 is fixedly provided at the upper end of the bag body 1 at a high position. The cap 13 matches the bag opening 101 of the bag body 1. Several wear-resistant parts are provided at equal intervals from top to bottom on the outside of the bag body 1. The wear-resistant parts include fixing ropes 8. Several fixing ropes 8 are fixedly provided around the bag body 1. A hemp rope 3 is passed through the center of the fixing ropes 8. A bottom sleeve is provided at the lower end of the bag body 1. Waterproof membrane layers 14 are provided on both the inner and outer sides of the bag body 1. An inner bag 2 is provided inside the bag body 1. The upper end of the inner bag 2 is fixedly connected to the upper inner side of the bag body 1.

[0029] With the above design, the bag opening 101 of the bag body 1 of this utility model is inclined and the cover 13 is designed so that water will be blocked by the cover 13 and will not splash into the bag body 1, thus protecting the items inside the bag body 1. The inclined design allows water splashed from the top of the cover 13 to be drained away by the inclination of the cover 13, and water will not accumulate on the cover 13. Therefore, it not only serves to waterproof the bag but also makes it less prone to damage, thus improving the service life of this utility model. The design of the fixing rope 8, hemp rope 3 and bottom sleeve makes the first layer of the bag body 1 in contact with the outside world the hemp rope 3 and the bottom sleeve, thus making the bag body 1 less prone to wear and tear, effectively improving the service life of this utility model. Moreover, the hemp rope 3 and the bottom sleeve can be replaced individually after wear, further improving the service life of this utility model.

[0030] A waterproof cloth 5 is fixedly installed on the upper end of the cap 13. Magnetic blocks 7 are embedded and fixedly installed on all four sides of the outer side of the bag body 1. Magnetic blocks 6 are embedded and fixedly installed on the bottom surface of the waterproof cloth 5 at the corresponding positions of magnetic blocks 7. Magnetic blocks 7 and corresponding magnetic blocks 6 are magnetically attracted to each other. External threaded posts 301 are fixedly installed at both ends of the hemp rope 3. A fixing cap 11 is fixedly installed on the outside of the external threaded posts 301 through threaded connection. The diameter of the fixing cap 11 is larger than the inner diameter of the fixing rope 8. The bottom sleeve includes a center surface 4, which matches the bottom end of the bag body 1. Connecting surfaces 401 are fixedly installed on all four sides of the center surface 4. The connecting surfaces 401 match the bottom ends of the corresponding sides of the bag body 1. A sub-hook and loop fastener 9 is fixedly installed on the side of the connecting surface 401 that contacts the bag body 1. A female hook and loop fastener 10 is fixedly installed on the bag body 1 at the corresponding positions of the sub-hook and loop fastener 9. The sub-hook and loop fastener 9 and the female hook and loop fastener 10 are attached and fixedly installed. A pull strap 201 is fixedly installed on the upper inner side of the inner bag 2.

[0031] Through the above design, the waterproof fabric 5 of this utility model not only protects the cover 13 and prevents it from directly contacting water, but also seals the gap between the cover 13 and the bag body 1, thereby achieving effective waterproofing. Magnetic block 1 7 and magnetic block 2 6 fix the waterproof fabric 5, thus fixing the cover 13. The external threaded post 301 and fixing cover 11 of this utility model ensure that after the hemp rope 3 passes through the corresponding fixing rope 8, the fixing cover 11 prevents the hemp rope 3 from easily detaching from the fixing rope 8. When the fixing cover 11 is removed, the hemp rope 3 can be removed and replaced. The female hook and loop fastener 9 and female hook and loop fastener 10 of this utility model facilitate the removal and replacement of the bottom cover. The pull strap 201 of this utility model allows the inner bag 2 to be pulled out during use, enabling effective cleaning of the hard-to-clean corners inside the inner bag 2.

[0032] Working principle: When in use, place the item into the inner bag 2, then rotate the cap 13 to cover the bag opening 101. Next, magnetically attach the magnetic blocks 6 and 7 on all four sides of the waterproof cloth 5. At this point, water cannot splash into the inner bag 2 through the bag opening 101, thus protecting the item. Water will also drain out through the top of the waterproof cloth 5 as the bag opening 101 tilts, preventing water accumulation at the top. During use, the hemp rope 3 and the bottom sleeve are the first surfaces to contact the outside environment, therefore they will wear out first, protecting the bag body 1 and effectively preventing wear. When the hemp rope 3 and bottom sleeve wear out... After a certain degree of damage, the screw caps 11 at both ends of the hemp rope 3 can be removed, replaced with new hemp rope 3, and then the screw caps 11 can be screwed back on to fix the hemp rope 3. The male Velcro 9 and female Velcro 10 of the connecting surface 401 can be separated, and the bottom cover can be removed. The center surface 4 of the new bottom cover is aligned with the lower end of the bag body 1, and then the male Velcro 9 and female Velcro 10 of the connecting surface 401 are attached and fixed, which effectively extends the service life of this utility model. The materials of the bag body 1, waterproof cloth 5, and waterproof membrane layer 14 of this utility model are all disclosed in the prior art, so this application will not elaborate further.

[0033] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
