[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-strength packaging bag includes a main body. A reinforcing auxiliary mechanism is provided on the inner wall of the main body. The reinforcing auxiliary mechanism includes a connecting piece fixedly connected to the inner wall of the main body. A connecting strip is attached to the rear end of the connecting piece. A tension strip is fixedly connected to one end of the connecting strip. A placement groove is formed at the upper end of the tension strip. A movable strip is movably connected to the inner side of the placement groove. A tensioning strip is fixedly connected to the lower end of the movable strip. A limiting piece is fixedly connected to the lower end of the tensioning strip. An adhesive piece is attached to the front end of the limiting piece. A movable shaft is movably connected inside the movable strip.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1-4As shown, a high-strength packaging bag includes a packaging bag body 1. A reinforcing auxiliary mechanism 5 is provided on the inner wall of the packaging bag body 1. The reinforcing auxiliary mechanism 5 includes a connecting piece 51 fixedly connected to the inner wall of the packaging bag body 1. A connecting strip 52 is attached to the rear end of the connecting piece 51. A tension strip 53 is fixedly connected to one end of the connecting strip 52. A placement groove 54 is opened at the upper end of the tension strip 53. A movable strip 55 is movably connected to the inner side of the placement groove 54. A tensioning strip 56 is fixedly connected to the lower end of the movable strip 55. A limiting piece 57 is fixedly connected to the lower end of the tensioning strip 56. An adhesive piece 58 is attached to the front end of the limiting piece 57. A movable shaft 59 is movably connected inside the movable strip 55. A support strip 510 is fixedly connected to the upper end of the movable strip 55.

[0015] In this embodiment, a limiting piece 511 is fixedly connected to the upper end of the support strip 510, and a connecting piece 512 is pasted to the front end of the limiting piece 511. The front end of the adhesive piece 58 is fixedly connected to the inner wall of the packaging bag body 1 near the lower side of the connecting piece 51. The movable shaft 59 extends into the interior of the pull strip 53, and the movable shaft 59 is movably connected to the pull strip 53. The front end of the connecting piece 512 is fixedly connected to the inner wall of the packaging bag body 1 near the connecting piece 51. The pull strip 53 and the movable strip 55 are distributed in a cross pattern. The movable strip 55, the tensioning strip 56, and the support strip 510 form a straight line. There are two sets of connecting pieces 51 and connecting pieces 52. Both sets of connecting pieces 52 are connected to the pull strip 53. There are two sets of reinforcing auxiliary mechanisms 5.

[0016] Specifically, first, the connecting strip 52 is attached to the connecting piece 51, the limiting piece 57 is attached to the adhesive piece 58, and the limiting piece 511 is attached to the connecting piece 512. This connects the tension strip 53, the tensioning strip 56, and the support strip 510 to the inner wall of the main body of the packaging bag 1, with the tension strip 53 and the movable strip 55 arranged in a crisscross pattern. Then, the item is placed inside the main body of the packaging bag 1. Under the weight of the item, the item presses down on the main body of the packaging bag 1, causing the main body of the packaging bag 1 to be stretched. This stretches the tension strip 53, the tensioning strip 56, and the support strip 510, thus limiting the main body of the packaging bag 1. This allows the main body of the packaging bag 1 to... The tensile force is transmitted to the tensile strip 53, the tension strip 56, and the support strip 510, preventing excessive stretching of the main body 1 of the packaging bag, thereby increasing the strength of the main body 1 of the packaging bag and enabling the main body 1 of the packaging bag to withstand high-strength tensile forces. By placing an item inside the main body 1 of the packaging bag and pressing the main body 1 of the packaging bag, the main body 1 of the packaging bag is stretched, thereby transmitting the tensile force to the tensile strip 53, the tension strip 56, and the support strip 510. This achieves the purpose of making the main body 1 of the packaging bag easily constrained by the tensile strip 53, the tension strip 56, and the support strip 510, and preventing excessive stretching of the main body 1 of the packaging bag, thereby increasing the strength of the main body 1 of the packaging bag and enabling the main body 1 of the packaging bag to withstand high-strength tensile forces.

[0017] In this embodiment, a connecting buckle 2 is fixedly connected to the front end of the packaging bag body 1, a pull rope body 3 is fixedly connected to the front end of the connecting buckle 2, and a handle strip 4 is fixedly connected to the upper end of the pull rope body 3.

[0018] Specifically, lifting the handle 4 causes the handle 4 to move the pull rope body 3 upward, and the pull rope body 3, through the connecting buckle 2, lifts the packaging bag body 1 upward, thus moving the item.

[0019] Working principle: In use, first attach the connecting strip 52 to the connecting piece 51, and attach the limiting piece 57 to the adhesive piece 58 and the limiting piece 511 to the connecting piece 512. This connects the pull strip 53, the tension strip 56, and the support strip 510 to the inner wall of the main body of the packaging bag 1, with the pull strip 53 and the movable strip 55 arranged in a crisscross pattern. Then, place the item inside the main body of the packaging bag 1 and lift the handle strip 4. This causes the handle strip 4 to move the pull rope body 3 upwards, and the pull rope body 3 lifts the main body of the packaging bag 1 upwards via the connecting buckle 2, thus moving the item. Under the weight of the item, the item presses down on the main body of the packaging bag 1, causing the main body of the packaging bag 1 to be pulled. This causes the main body of the packaging bag 1 to pull the pull strip 53, the tension strip 56, and the support strip 510, thus causing the main body of the packaging bag 1 to be pulled. The restraints provided by the tension strips 53, 56, and 510 allow the main body of the packaging bag 1 to transfer the tensile force to the tension strips 53, 56, and 510, preventing excessive stretching of the main body of the packaging bag 1. This enhances the strength of the main body of the packaging bag 1, enabling it to withstand high-strength tensile forces. By placing an item inside the main body of the packaging bag 1 and pressing it down, the main body of the packaging bag 1 is subjected to tension, which in turn transfers the tensile force to the tension strips 53, 56, and 510. This achieves the purpose of ensuring that the main body of the packaging bag 1 is restrained by the tension strips 53, 56, and 510, preventing excessive stretching and enhancing its strength, thus enabling it to withstand high-strength tensile forces.
