[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1 to 4As shown, an environmentally friendly paper corner protector with moisture-proof and antibacterial properties includes a main paper corner protector 1. Both ends of the main paper corner protector 1 have two first assembly slots 3. An auxiliary paper corner protector 2 is detachably installed at the end of the main paper corner protector 1. One end of the auxiliary paper corner protector 2 is a straight edge, and the other end is a beveled edge. The beveled edge of the auxiliary paper corner protector 2 has a snap-fit ​​slot 4, and the straight edge of the auxiliary paper corner protector 2 has two second assembly slots 9. Anti-detachment snap-fit ​​hollow cardboard 7 is snapped into the inner side of the first assembly slots 3 and the second assembly slots 9. The auxiliary paper corner protectors 2 are assembled with each other via right-angle snap-fit ​​plates 5. The main paper corner protector 1 is assembled with each other, and the auxiliary paper corner protector 2 is assembled with the main paper corner protector 1 via anti-detachment snap-fit ​​hollow cardboard 7. The main paper corner protector 1 is assembled according to the length of the actual item and the protection requirements, allowing the paper corner protector to be suitable for different lengths and corner positions.

[0020] Both ends of the right-angle snap-fit ​​plate 5 are provided with V-shaped structural grooves 6. The distance between the two sides of the right-angle snap-fit ​​plate 5 is greater than the thickness of the right-angle snap-fit ​​plate 5. The presence of the V-shaped structural grooves 6 allows the two sides of the right-angle snap-fit ​​plate 5 to move closer to each other after being squeezed, thus realizing the installation of the right-angle snap-fit ​​plate 5.

[0021] The cross-section of the first assembly groove 3 is convex, and the structure of the anti-detachment snap-fit ​​hollow cardboard 7 is I-shaped. After the I-shaped anti-detachment snap-fit ​​hollow cardboard 7 is snapped into the first assembly groove 3, it will not easily come loose, ensuring the stability of the main paper corner protector 1 after it is connected to the main paper corner protector 1.

[0022] The two ends of the anti-detachment hollow cardboard 7 are recessed inward to form a buffer groove 8. The width of the buffer groove 8 is greater than the position difference between the inner walls of the first assembly groove 3. The presence of the buffer groove 8 allows the width of the anti-detachment hollow cardboard 7 to narrow when it is squeezed inward from the side, so as to facilitate the assembly of the anti-detachment hollow cardboard 7 with the first assembly groove 3.

[0023] Both the main paper corner protector 1 and the auxiliary paper corner protector 2 are coated with a waterproof coating. The raw material of the waterproof coating is an anti-peeling paint. The waterproof coating increases the waterproof performance of the main paper corner protector 1 and the auxiliary paper corner protector 2, preventing them from becoming soft and unable to protect the items after getting wet.

[0024] Working principle: When using paper corner protectors to protect items, first select an appropriate number of main paper corner protectors 1 according to the location to be protected and the actual length of the item. When assembling the main paper corner protectors 1 according to the length and width of the item, press the two ends of the anti-detachment hollow cardboard 7 inwards so that the inner walls of the buffer groove 8 fit together. Then, insert the pressed anti-detachment hollow cardboard 7 into the first assembly groove 3. After the anti-detachment hollow cardboard 7 is connected to the two main paper corner protectors 1, bring the two main paper corner protectors 1 closer together until they touch. When touched, the anti-detachment hollow cardboard 7 is fully inserted into the first assembly slot 3 and elastically restored. When protecting the corner of the item, the auxiliary paper corner protector 2 and the main paper corner protector 1 are assembled through the anti-detachment hollow cardboard 7. Then, the two ends of the right-angle clamping plate 5 are squeezed and inserted into the clamping slot 4 at the end of the auxiliary paper corner protector 2. The two auxiliary paper corner protectors 2 are then attached to each other, so that the main paper corner protector 1 and the auxiliary paper corner protector 2 form a right-angle structure. This allows the paper corner protectors to be suitable for different lengths and sizes and to protect the corner of the item. The assembled paper corner protectors can be disassembled, recycled, and reused multiple times.
