DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a high-strength packaging carton, including a waterproof layer 1, the surface of the waterproof layer 1 is coated with a waterproof coating, and the waterproof layer 1 itself is also made of waterproof material, which can prevent moisture from invading the interior of the box and causing damage to the box. A reinforcing layer 2 is fixedly installed inside the waterproof layer 1, and a filler and a wire mesh are arranged inside the reinforcing layer 2 to increase its strength. A cardboard layer 3 is fixedly installed inside the reinforcing layer 2, and a honeycomb board layer 4 is fixedly installed inside the cardboard layer 3. The honeycomb board layer 4 has the characteristics of lightness, high strength, not easy to deform, good impact resistance and cushioning, environmental protection and recyclability, as well as waterproof and moisture-proof. The honeycomb board layer 4 is suitable for packaging heavy objects and fragile items because of its strong structure and can provide effective protection. A storage layer 5 is fixedly installed inside the honeycomb board layer 4. The cardboard layer 3 and the storage layer 5 are corrugated cardboard, which can reduce the friction of the items during transportation or handling. Reinforced corners 6 are fixedly installed at the four corners of the bottom of the storage layer 5. Protective brackets 7 are fixedly installed between the reinforced corners 6, and protective corners 8 are fixedly installed around the surface of the waterproof layer 1. The reinforced corners 6 and the protective corners 8 can protect the corrugated inside and outside of the packaging carton. The protective bracket 7 can protect the interior of the packaging carton, a bottom plate 9 is fixedly installed at the inner bottom of the storage layer 5, and circular grooves 10 are opened at equal intervals on the top of the bottom plate 9. Springs 11 are fixedly installed at the inner bottom of the circular grooves 10, and a movable plate 12 located inside the circular grooves 10 is fixedly installed on the top of the spring 11, and the outer surfaces of the spring 11 and the movable plate 12 are movably connected with the inner surface of the circular groove 10. When the movable plate 12 is impacted, it will squeeze the spring 11 to make it in a compressed state, thereby buffering the impact force.

[0021] A movable rod 13 is fixedly installed at an equal distance on the top of the bottom plate 9. The bottom of the movable rod 13 passes through the bottom plate 9 and is fixedly connected to the top of the movable plate 12. A loading plate 14 is fixedly installed on the top of the movable rod 13. When the loading plate 14 is impacted, it will drive the movable rod 13 to slide, thereby driving the movable plate 12 to slide synchronously inside the circular groove 10. Square grooves 15 are opened on both sides of the waterproof layer 1, the reinforcement layer 2, the paperboard layer 3, the honeycomb layer 4 and the storage layer 5, and the inside of the square groove 15 is fixedly installed with a groove sleeve 16. The square groove 15 and the groove sleeve 16 are convenient for packaging cartons. Handling, the top ends of the waterproof layer 1, the reinforcement layer 2, the cardboard layer 3, the honeycomb board layer 4 and the storage layer 5 are all movably installed with closed cardboards 17, the number of closed cardboards 17 is two, and the two closed cardboards 17 have the same size. The closed cardboard 17 can encapsulate the packaging carton to make it in a closed state, the bottom of the waterproof layer 1 and the protective corner 8 are fixedly installed with support blocks 18, and the bottom of the waterproof layer 1 is fixedly installed with horizontal bars 19 at equal distances. The support blocks 18 and the horizontal bars 19 can make the box body stand on the ground, thereby preventing moisture from invading the interior of the box body and reducing damage to the box body.

[0022] Working principle: When the packaging carton needs to be used, the operator first places the items inside the storage layer 5 and on the top of the carrier plate 14. During the transportation and handling process, impact force will be generated. At this time, the carrier plate 14 will squeeze the movable rod 13, and the movable rod 13 will drive the movable rod 13 to slide inside the circular groove 10, thereby squeezing the spring 11, so that it is in a compressed state, which can buffer the impact force. Secondly, the packaging carton can be easily carried through the square groove 15 and the groove sleeve 16. Finally, the design of the waterproof layer 1 can prevent moisture from invading the interior of the box, which is good for the box. The reinforcing layer 2 is provided with fillers and wire mesh inside to increase its strength. The design of the honeycomb board layer 4 makes its structure more solid, which can effectively package heavy and valuable items. The cardboard layer 3 and the storage layer 5 are corrugated cardboard to reduce the friction on the items. The reinforcing corners 6 and the protective corners 8 can protect the inner and outer corners of the packaging carton. The protective bracket 7 can protect the inside of the packaging carton, thereby increasing its overall strength. When the packaging carton is placed on the ground, the bottom of the support block 18 and the horizontal bar 19 will first contact the ground, making it in a suspended state, so that moisture-proof work can be performed.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
