[0021] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a technical solution: a reusable packaging bag, comprising a first U-shaped plate 1, a hinge 2 is installed on the right side of the first U-shaped plate 1, a second U-shaped plate 3 is installed on the left side of the hinge 2, a packaging bag body 4 is installed inside the first U-shaped plate 1 and the second U-shaped plate 3, a handle 5 is fixedly connected to one end of the packaging bag body 4, a first hollow block 6 is fixedly connected to the left side of the first U-shaped plate 1, a second hollow block 7 is fixedly connected to the left side of the second U-shaped plate 3, and the top of the first hollow block 6 is fixedly connected to the second U-shaped plate 3. A circular hole 8 is provided at the bottom, a round rod 9 is slidably connected to the inside of the circular hole 8, an L-shaped plate 10 is fixedly connected to the top of the round rod 9, and a card slot 11 is provided at the top and bottom of the second hollow block 7. The staff presses the round rod 9 to make the round rod 9 drive the L-shaped plate 10 to shrink into the inside of the first hollow block 6, and the L-shaped plate 10 will be disengaged from the card slot 11, thereby releasing the limiting relationship between the first U-shaped plate 1 and the second U-shaped plate 3, so that the staff can unfold the inside of the packaging bag body 4 and clean the inside.
[0023] Reference Figure 4 As shown, in this embodiment: a limiting hole 12 is opened on the top of the L-shaped plate 10, and a limiting rod 13 is fixedly connected to the inside of the first hollow block 6. By setting the limiting hole 12 and the limiting rod 13, the limiting rod 13 can make the L-shaped plate 10 more stable when moving, and prevent the L-shaped plate 10 from shifting or shaking during the movement. At the same time, the cooperation of the limiting rod 13 and the limiting hole 12 can enable the L-shaped plate 10 to be accurately inserted into the inside of the slot 11.
[0024] Reference Figure 4 As shown, in this embodiment: the inner wall of the L-shaped plate 10 is fixedly connected with a reset spring 14. By setting the reset spring 14, the reset spring 14 can enable the L-shaped plate 10 to automatically reset when not subjected to external force, thereby realizing automatic locking of the first U-shaped plate 1 and the second U-shaped plate 3, making it more stable for the staff when fixing.
[0025] Reference Figure 5 As shown, in this embodiment: the material of the wear-resistant layer 401 is polyamide. The polyamide material has excellent wear resistance. The amide bonds in its molecular chain structure make the polyamide material have high mechanical strength and wear resistance, and can maintain stable performance under various friction conditions. When the packaging bag body 4 is subjected to friction from external objects, the wear resistance of the polyamide material can effectively resist wear and extend the service life of the packaging bag.
[0026] Reference Figure 5As shown, in this embodiment: the material of the corrosion-resistant layer 402 is polyethylene terephthalate, which is a material with good corrosion resistance and can resist the erosion of various chemical substances. Its molecular chain structure is tight and stable, so that it can still maintain its original physical properties and chemical stability when facing strong corrosive substances such as acids, alkalis, and organic solvents. This characteristic enables the packaging bag body 4 to play its protective role in various harsh environments and ensure the safety of the items in the packaging bag body 4.
[0027] Reference Figure 5 As shown, in this embodiment: the material of the waterproof layer 403 is high-density polyethylene, which is a linear thermoplastic with high crystallinity and density. This unique structure makes HDPE have good permeability resistance and water resistance. When water contacts the surface of HDPE, it is not easy to be adsorbed due to its low surface tension, thereby effectively preventing the penetration of water.
[0028] The practical working principle of the present invention is as follows: the staff presses the round rod 9 so that the round rod 9 drives the L-shaped plate 10 to retract into the inside of the first hollow block 6, and the L-shaped plate 10 will disengage from the card slot 11, thereby releasing the limiting relationship between the first U-shaped plate 1 and the second U-shaped plate 3, so that the staff can unfold the inside of the packaging bag body 4 and clean the inside. By setting the limiting hole 12 and the limiting rod 13, the limiting rod 13 can make the L-shaped plate 10 more stable when moving, and prevent the L-shaped plate 10 from deflecting or shaking during the movement. At the same time, the cooperation of the limiting rod 13 and the limiting hole 12 can enable the L-shaped plate 10 to be accurately inserted into the inside of the card slot 11. By setting the reset spring 14, the reset spring 14 can enable the L-shaped plate 10 to automatically reset when not subjected to external force, thereby realizing the automatic locking of the first U-shaped plate 1 and the second U-shaped plate 3, making the staff more stable when fixing. The polyamide material has excellent wear resistance. The amide bond in its molecular chain structure makes the polyamide material have high mechanical strength and wear resistance, and can maintain stable performance under various friction conditions. When the packaging bag body 4 is rubbed by external objects, the wear resistance of the polyamide material can effectively resist wear and extend the service life of the packaging bag. Polyethylene terephthalate is a material with good corrosion resistance and can resist the erosion of various chemical substances. Its molecular chain structure is tight and stable, so that it can still maintain its original physical properties and chemical stability when facing strong corrosive substances such as acids, alkalis, and organic solvents. This characteristic enables the packaging bag body 4 to play its protective role in various harsh environments and ensure the safety of the items in the packaging bag body 4. High-density polyethylene is a thermoplastic plastic with a linear structure and high crystallinity and density. This unique structure makes HDPE have good permeability resistance and water resistance. When water contacts the surface of HDPE, due to its low surface tension, water is not easily adsorbed, thereby effectively preventing water penetration.
