[0015] Please see Figure 1-4 This utility model provides a technical solution: a top cover for a packaging box that can be used with a zigzag pallet. The top cover body 1 is disposed on the upper surface of the packaging box 2, and the bottom of the packaging box 2 is connected to the zigzag pallet 3. The top cover body 1 has four upper bosses 4 arranged in a 2x2 matrix on its upper surface. Positioning corner guards 5 are provided at each of the four corners of the top cover body 1. A surrounding plate 6 is disposed around the lower surface of the top cover body 1. A lower boss 7 is disposed on the lower surface of the top cover body 1, and a groove 11 is formed between the lower boss 7 and the surrounding plate 6. The groove 11 on the lower surface of the top cover body 1 interacts with the packaging box. 2. The top end is inserted to connect and separate the top cover body 1 from the packaging box 2. Several first ribs 8 are provided on the lower surface of the top cover body 1 and in the groove 11. Several second ribs 9 are provided on the outer wall of the surrounding plate 6. Several ribs 10 are provided on the inner side of the surrounding plate 6 and at the outer end of the groove 11. The lower boss 7 is densely covered with concave support columns 12. The top end of the support column 12 is connected to the lower surface of the top cover body 1. The top cover body 1, the surrounding plate 6, the upper boss 4, the lower boss 7 and the support column 12 are all integrally molded structures and are made by vacuum forming process. The double-layer structure greatly improves the load-bearing capacity. The positioning corner protector 5 includes a base plate 501 and corner protector baffles 502. Corner protector baffles 502 are provided along the outer edge of the upper surface of the base plate 501. The positions of the corner protector baffles 502 correspond one-to-one with the positions of the four outer corners of the bottom of the zigzag pallet 3. The base plate 501 has countersunk holes 503. The base plate 501 is fastened to the top cover body 1 through the countersunk holes 503 and bolts, thus achieving the connection between the base plate 501 and the top cover body 1. Furthermore, the use of countersunk holes does not affect the support of the side support seats 13 at the bottom of the zigzag pallet 3. Side support seats 13 are provided on both sides of the bottom of the zigzag pallet 3. A central support seat 14 is provided at the bottom center of the tray 3. There is space between the central support seat 14 and the two side support seats 13. The space between the central support seat 14 and the two side support seats 13 corresponds to the position of the two upper protrusions 4. The inner wall of the corner guard 502 and the outer walls of the two corners at the outer end of the side support seat 13 are located on the same vertical plane to ensure that when two packaging boxes 2 are stacked, the outer corners of the side support seats 13 on both sides of the bottom of the upper packaging box 2 fit perfectly with the corner guard 502, ensuring the stability during stacking.

[0016] Installation Method and Operating Principle: The top cover body 1 is manufactured using a vacuum forming process. The top cover body 1 is surrounded by a perimeter plate 6, and its upper surface has four upper protrusions 4 arranged in a two-by-two matrix. The bottom of the top cover body 1 has a lower protrusion 7 with a recessed support column 12, making the top cover body 1 a double-layer structure. The lower surface of the top cover body 1, located in the groove 11, is densely covered with first ribs 8, and the outer wall of the perimeter plate 6 is densely covered with second ribs 9. A raised strip 10 is located on the inner side of the perimeter plate 6 at the outer end of the groove 11. This structure ensures structural strength. In use, the groove 11 of the top cover body 1 is fitted into the top of the packaging box 2. The top of the packaging box 2 is inserted between the raised strip 10 and the lower protrusion 7 on the inner side of the top cover body 1, and friction prevents it from falling off. The three-section tray 3 is securely connected to the bottom of the packaging box 2 with bolts. When transporting or storing stacked items, the bottom of one of the packaging boxes 2 is supported by the cross-shaped pallet 3 on the top surface of the top cover body 1 of the other packaging box 2, and the two sides of the outer end of the side support seat 13 of the cross-shaped pallet 3 are supported on the bottom plate 501 of the corresponding positioning corner protector 5. The outer wall of the side support seat 13 is in close contact with the inner wall of the corner protector baffle 502 of the positioning corner protector 5, thus completing the stacking of the two packaging boxes 2. Figure 5-6As shown. In terms of size, the following four types of plastic pallets on the market, namely the 1200*1000 three-line bottom pallet, the 1200*1000 three-line bottom collapsible box, the 1200*800 (U87) bin, and the 1200*800 three-line bottom pallet, cannot share the same top cover. The main body of the top cover in this application has dimensions of 1225*1025*63mm. When the 1225*1025*63mm top cover body 1 is used with a 1200*1000 zigzag bottom pallet and a 1200*1000 zigzag bottom side panel box, the four corners of the 1200*1000 zigzag bottom pallet and the 1200*1000 zigzag bottom side panel box mate with the positioning corner protectors 5. When the 1225*1025*63mm top cover body 1 is used with a smaller zigzag pallet 3, for example, when the 1225*1025*63mm top cover body 1 is used with a 1208 zigzag pallet 3 (size 1200*800mm), the inner side of the side support seat 13 at the bottom of the 1208 zigzag pallet 3 engages with the outer side of the upper boss 4, which also prevents the upper packaging box from collapsing. Figure 7 As shown. This utility model has a reasonable structure. The upper surface of the top cover body 1 is provided with upper protrusions 4 arranged in a matrix of two by two, and each of the four corners of the upper surface of the top cover body 1 is provided with positioning corner guards 5. When two packaging boxes 2 are stacked together, the four corners of the three-dimensional pallet 3 at the bottom of the upper packaging box 2 are respectively limited by the positioning corner guards 5 to prevent tipping, tilting or slipping during stacking, transportation or placement. In addition, the four upper protrusions 4 can be used with a smaller three-dimensional pallet, which greatly improves the versatility and applicability. The lower surface of the top cover body 1 is provided with a lower protrusion 7, which is supported by several support columns 12 on the protrusions 4 on the lower surface of the top cover body 1. The double-layer structure of the top cover body 1 greatly improves the load-bearing capacity of the top cover body 1. At the same time, several first ribs 8 are provided on the lower surface of the top cover body 1 and located in the groove 11, and several second ribs 9 are provided on the outer wall of the surrounding plate 6, which greatly improves the structural strength of the top cover body 1 itself, reduces the probability of breakage or damage to the top cover body 1, and thus improves the service life.
