[0021] Please see Figures 1-5This utility model provides an embodiment of a cardboard box corner reinforcement support structure, including a cardboard box body 1, a limiting block 101, and a fixing assembly. A protective foot plate 2 is provided on the outside of the cardboard box body 1, and a protective vertical plate 3 is provided on the inner side of the protective foot plate 2. Holes are opened above the protective vertical plate 3 and the protective foot plate 2, and the limiting block 101 is provided inside the holes. A spring 102 is provided above the limiting block 101, and a connecting rod 103 is provided on the inner side of the spring 102. A mounting plate 104 is provided above the connecting rod 103, and a rotating handle 105 is provided on the outer side of the mounting plate 104. The connecting rod 103 and the rotating handle 105 are connected by a pivot. By pulling the rotating handle 105, the rotating handle 105 moves upward, causing the connecting rod 103 to move upward, and the upward movement of the connecting rod 103 causes the spring 102 to contract. The spring 102 retracts upward, causing the limiting block 101 to move in the same direction as the connecting rod 103. The limiting block 101 enters from the hole above the protective foot plate 2 into the hole above the protective vertical plate 3. The protective foot plate 2 and the protective vertical plate 3 are connected by the fixing assembly. By lowering the rotating handle 105, the connecting rod 103 is driven downward, and the spring 102 is driven to rebound downward, thus fixing the limiting block 101 into the hole of the protective vertical plate 3. This facilitates the fixing of the carton when installing the corners of the carton, reduces the difficulty of the operation during the installation process, ensures that the corners of the carton are firmly installed around the carton, improves the installation efficiency, and efficiently separates materials during the recycling process, improving recycling efficiency and quality, and reducing recycling processing time and costs.
[0022] Please see Figures 1-5 In this embodiment, a groove is provided on the inner side of the protective foot plate 2, and a first sliding plate 201 is provided on the inner side of the groove. The first sliding plate 201 slides inside the protective foot plate 2. Holes are provided above the protective foot plate 2 and the first sliding plate 201. Multiple sets of holes are provided. The first sliding plate 201 slides inside the protective foot plate 2. When the first sliding plate 201 slides to any position, it is fixed to the protective foot plate 2 by bolts. Thus, the width of the protective foot plate 2 can be adjusted according to the width of the carton. A groove is provided on the upper side of the protective vertical plate 3, and a second sliding plate 202 is provided inside the groove. The second sliding plate 202 slides inside the protective vertical plate 3. Holes are provided above the protective vertical plate 3 and the second sliding plate 202. Multiple sets of holes are provided. The second sliding plate 202 slides inside the protective vertical plate 3. When the second sliding plate 202 slides to any position, it is fixed to the protective vertical plate 3 by bolts. Thus, the height of the protective vertical plate 3 can be adjusted.
[0023] Please see Figures 1-5In this embodiment, multiple sets of protective foot plates 2 are provided, and the multiple sets of protective foot plates 2 are respectively provided above the corners of the carton body 1. Multiple sets of first sliding plates 201 are provided, and are respectively provided inside the protective foot plates 2 at the two corners of the carton body 1. Multiple sets of second sliding plates 202 are provided, and are respectively provided inside the protective foot plates 2 at the upper and lower corners of the carton body 1. By providing protective foot plates 2 above the corners of the carton body 1, all corners of the carton body 1 can be protected. The protective vertical plate 3 and the protective foot plates 2 can protect all edges and corners of the carton body 1.
[0024] During operation, pulling the rotating handle 105 moves the connecting rod 103 upward, causing the spring 102 to contract. The spring 102 then moves the limiting block 101 in the same direction as the connecting rod 103. The limiting block 101 is inserted from the hole above the protective foot plate 2 into the hole above the protective vertical plate 3, connecting the protective foot plate 2 and the protective vertical plate 3 via a fixing assembly. Lowering the rotating handle 105 moves the connecting rod 103 downward, causing the spring 102 to rebound, thus fixing the limiting block 101 into the hole in the protective vertical plate 3. This facilitates the fixing of the carton corners during installation, reducing the difficulty of the installation process and ensuring the carton corners are securely installed around the carton, improving efficiency. To improve installation efficiency, materials are efficiently separated during the recycling process, enhancing recycling efficiency and quality while reducing recycling time and costs. Multiple sets of holes are provided above the foot plate and the first sliding plate 201. The first sliding plate 201 slides inside the protective foot plate 2, and when it reaches any position, it is fixed to the protective foot plate 2 with bolts, allowing for width adjustment of the protective foot plate 2 according to the width of the carton. Similarly, the second sliding plate 202 slides inside the protective vertical plate 3, and when it reaches any position, it is fixed to the protective vertical plate 3 with bolts, allowing for height adjustment of the protective vertical plate 3. Protective foot plates 2 are provided above the corners of the carton body 1, protecting all corners of the carton body 1. The protective vertical plate 3 and the protective foot plates 2 protect all edges and corners of the carton body 1.
[0025] Through the above steps, by pulling the rotating handle 105, the rotating handle 105 moves upward, causing the connecting rod 103 to move upward. The upward movement of the connecting rod 103 causes the spring 102 to contract. The upward contraction of the spring 102 causes the limiting block 101 to move in the same direction as the connecting rod 103. By inserting the limiting block 101 from the hole above the protective foot plate 2 into the hole above the protective vertical plate 3, the protective foot plate 2 and the protective vertical plate 3 are connected by the fixing assembly. By lowering the rotating handle 105, the rotating handle 105 moves the connecting rod 103 downward, causing the connecting rod 103 to move downward, causing the spring 102 to rebound. Thus, the limiting block 101 can be fixed into the hole of the protective vertical plate 3. This facilitates the fixing of the carton when installing the carton corners, reduces the operational difficulty during the installation process, ensures that the carton corners are firmly installed around the carton, improves installation efficiency, and efficiently separates materials during the recycling process, improving recycling efficiency and quality, and reducing recycling processing time and costs.
