Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, specifically a recyclable, damage-resistant packaging bag. Background Technology

[0002] Packaging bags are bags used to package various goods, facilitating transportation and storage during production and distribution. They are widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags end up in landfills like ordinary garbage, with only 7% being recycled. Packaging bags are generally classified into plastic packaging bags and composite packaging bags based on their manufacturing process. Plastic packaging bags include woven plastic bags and plastic film bags. The former are lightweight, high-strength, and corrosion-resistant; with a plastic film lining, they can prevent moisture and dampness. Composite packaging bags combine materials with different properties to improve the air permeability, moisture permeability, oil resistance, water resistance, and chemical resistance of the packaging material, enabling it to function as an insect repellent, dustproof, microbial barrier, and barrier against light, fragrance, and odor.

[0003] Research revealed that some existing ordinary packaging bags are simple in workmanship and use limited materials. During transportation or storage, they are easily exposed to external objects or torn by the packaging material, losing their ability to hold and carry items. This results in a short service life for the packaging bags, which is detrimental to environmental protection and resource utilization. In response to the above situation, technological innovation will be carried out based on the existing devices. Utility Model Content

[0021] Please see Figure 1-4 This utility model provides a technical solution: a recyclable, damage-resistant packaging bag, including a bag body 1, the inside of which can hold items. A handle 2 is fixedly connected to the outer surface of the bag body 1, allowing the user to lift the bag body 1 more easily. A first protective shell 3 and a second protective shell 4 are fixedly connected to the outer surface of the bag body 1. Both the first protective shell 3 and the second protective shell 4 have L-shaped cross-sections. A positioning groove 15 is provided on one side of the second protective shell 4. A positioning block 14 is fixedly connected to one side of the first protective shell 3. The surface of the positioning block 14 is inserted into the interior of the positioning groove 15. When the bag body 1... After folding up and down, the bag body 1 is folded left and right, and the positioning block 14 is inserted into the positioning groove 15, so that the first protective shell 3 and the second protective shell 4 can fold and protect the bag body 1 more smoothly. The second protective shell 4 has a power groove 7 inside, and the cross-section of the power groove 7 is also L-shaped. There are two symmetrical mounting brackets 12 slidably connected inside the power groove 7. The adjacent sides of the two mounting brackets 12 are provided with inclined surfaces. The positioning block 14 has a fixing groove 13 extending to the outside of the positioning block 14 inside. The surface of the mounting bracket 12 is slidably connected to the inside of the fixing groove 13.

[0022] The bag body 1 is internally fixed with reinforcing ribs 6. The strength of the bag body 1 can be improved by the cooperation of reinforcing ribs 6 and handles 2. At the same time, handles 2 and reinforcing ribs 6 do not affect the folding of the bag body 1.

[0023] The first transmission frame 8 and the second transmission frame 11 are fixedly connected to the adjacent sides of the two mounting brackets 12 respectively. The surfaces of the first transmission frame 8 and the second transmission frame 11 are slidably connected to the inside of the power groove 7. The inside of the power groove 7 is rotatably connected to a gear 16, which is located between the first transmission frame 8 and the second transmission frame 11.

[0024] The first transmission frame 8 and the second transmission frame 11 are both provided with teeth on the side near the gear 16. The surfaces of the first transmission frame 8 and the second transmission frame 11 are connected to the surface of the gear 16 through tooth meshing. The rotation of the gear 16 enables the first transmission frame 8 and the second transmission frame 11 to move relative to each other, and enables the device to operate more smoothly.

[0025] A spring 9 is fixedly connected to the top of the first transmission frame 8. The top of the spring 9 is fixedly connected to the inner wall of the power groove 7. The spring 9 can be compressed and reset by moving the first transmission frame 8.

[0026] A rotating column 5 is fixedly connected to one side of the gear 16. The end of the rotating column 5 away from the gear 16 rotates through the inside of the power groove 7 and extends to the outside of the second protective shell 4. The operator can drive the gear 16 to rotate by rotating the column 5.

[0027] The first transmission frame 8 has a transmission groove 10, and the interior of the transmission groove 10 is slidably connected to the surface of the second transmission frame 11. Through the transmission groove 10, the first transmission frame 8 and the second transmission frame 11 can move relative to each other more smoothly.

[0028] After the positioning block 14 slides into the positioning groove 15, the inclined surface on the mounting bracket 12 allows the positioning block 14 to push the two mounting brackets 12 to move, and compresses the spring 9. When the positioning block 14 moves to the appropriate position, the spring 9 returns to its original position, causing the mounting bracket 12 to slide into the vertical groove of the fixing groove 13. This fixes the positions of the first protective shell 3 and the second protective shell 4, and enables the first protective shell 3 and the second protective shell 4 to more stably protect the bag body 1. At the same time, the first protective shell 3 and the second protective shell 4 can reduce the impact of objects in the external environment on the bag body 1, thus preventing damage to the bag body 1 and affecting its recycling. This allows the bag body 1 to be stored and recycled more smoothly.

[0029] Working Principle: For this type of reusable, breakage-resistant packaging bag, the strength of the bag body 1 is enhanced by the cooperation of the reinforcing ribs 6 and the handles 2. When the bag body 1 is folded vertically, it is folded horizontally, allowing the positioning block 14 to be inserted into the positioning groove 15. This enables the first protective shell 3 and the second protective shell 4 to fold and protect the bag body 1 more smoothly. After the positioning block 14 slides into the positioning groove 15, the inclined surface on the mounting bracket 12 allows the positioning block 14 to push the two mounting brackets 12 to move, compressing the spring 9. When the positioning block 14 moves to the appropriate position, the spring 9 returns to its original position, causing the mounting bracket 12 to slide into the vertical groove of the fixing groove 13. This fixes the positions of the first protective shell 3 and the second protective shell 4, making them more stable in protecting the bag body 1. At the same time, the first protective shell 3 and the second protective shell 4 can reduce the impact of objects in the external environment on the bag body 1, preventing damage and breakage that could affect the reusability of the bag body 1.
