DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0028] A packaging carton with a structure convenient for taking out, including a U-shaped main board 1, side boards 2, an upper cover board 3 and side cover boards 4. The side boards 2 are arranged on both sides of the U-shaped main board 1, and the bottom ends of the side boards 2 are integrally provided with both sides of the U-shaped main board 1. The upper cover board 3 is arranged on the front and rear sides of the top of the U-shaped main board 1, and the side cover boards 4 are arranged on the tops of the opposite sides of the two side boards 2. The upper cover board 3 and the side cover boards 4 are respectively integrally provided with the U-shaped main board 1 and the side boards 2. Connecting components 5 are arranged on the front and rear sides of the side boards 2 close to the U-shaped main board 1, and one side of the connecting components 5 close to the U-shaped main board 1 extends into its interior;

[0029] The connecting component 5 includes connecting blocks 51 which are respectively arranged on the front and rear sides of the side boards 2 close to the U-shaped main board 1. Elastic clamping plates 52 are arranged on the front and rear sides of the connecting blocks 51, and a plurality of positioning springs 53 are arranged on one side of the elastic clamping plates 52 close to the connecting blocks 51. One side of the positioning springs 53 close to the connecting blocks 51 is connected to them, and one side of the elastic clamping plates 52 close to the inner wall of the U-shaped main board 1 is in close contact with it.

[0030] In this embodiment: By setting the connecting component 5, the connecting blocks 51 can enter the U-shaped main board 1 by deflecting the two side boards 2. When the connecting blocks 51 enter the U-shaped main board 1, the elastic clamping plates 52 will first contact the inner wall of the U-shaped main board 1. Limited by the space, the two elastic clamping plates 52 on the front and rear sides are deformed towards the connecting blocks 51 and squeeze the positioning springs 53. Therefore, when the connecting blocks 51 are inside the U-shaped main board 1, through the elasticity of the elastic clamping plates 52 and the positioning springs 53, the elastic clamping plates 52 can be firmly in the U-shaped clamping plate and not easily come out, effectively ensuring the firm connection between the side boards 2 and the U-shaped main board 1. And since both the U-shaped main board 1 and the side boards 2 are composed of two kraft paper covering layers 11, a reinforcing layer 12 and a buffer layer 13, the structural strength of the packaging carton during use can be improved, the damage of the packaging carton can be reduced, the service life of the packaging carton can be effectively extended, and the environmental protection of the recycling use of the packaging carton can be enhanced.

[0031] Specifically, as Figure 2As shown, the elastic clamping plate 52 is arranged obliquely, and the end of the elastic clamping plate 52 far from the connecting block 51 is arranged at a right angle. A non-slip protrusion is arranged on the side of the right-angle end close to the inner wall of the U-shaped main board 1 and is in close contact with the inner wall of the U-shaped main board 1.

[0032] Specifically, as Figure 1 , Figure 3 shown, connecting grooves 6 are formed on the front side and the rear side of both sides of the U-shaped main board 1, and the connecting block 51 is located inside the connecting groove 6.

[0033] Specifically, as Figure 1 , Figure 3 shown, two hook-and-loop fastener rough surfaces 7 are bonded to the front side and the rear side of both sides of the U-shaped main board 1, and a hook-and-loop fastener hook surface 8 is bonded to the side of the side board 2 close to the hook-and-loop fastener rough surface 7. The hook-and-loop fastener hook surface 8 and the hook-and-loop fastener rough surface 7 are used in cooperation.

[0034] In this embodiment: By providing the connecting groove 6, it is convenient for the connecting block 51 to enter the inside of the U-shaped main board 1 and be connected to it. By arranging the end of the elastic clamping plate 52 far from the connecting block 51 at a right angle and providing a non-slip protrusion, the contact area between the elastic clamping plate 52 and the inner wall of the connecting groove 6 can be increased, and the friction force can be increased, so that the connecting block 51 is not easily disengaged from the connecting groove 6. By the cooperation of the hook-and-loop fastener hook surface 8 and the hook-and-loop fastener rough surface 7, the connection firmness between the side board 2 and the U-shaped main board 1 can be further improved.

[0035] Specifically, as Figure 1 shown, creases are provided at the joints of the U-shaped main board 1 and the side board 2, the U-shaped main board 1 and the upper cover board 3, and the side board 2 and the side cover board 4. The U-shaped main board 1 and the side board 2, the U-shaped main board 1 and the upper cover board 3, and the side board 2 and the side cover board 4 are folded along the creases.

[0036] In this embodiment: Through the provision of the creases, it is convenient for the U-shaped main board 1 and the side board 2, the U-shaped main board 1 and the upper cover board 3, and the side board 2 and the side cover board 4 to be folded along the creases.

[0037] Specifically, as Figure 1 , Figure 3 shown, two reinforcing bars 9 are provided on the front side and the rear side of the inner wall of the U-shaped main board 1 opposite to the two side boards 2, and the two reinforcing bars 9 are arranged in an X shape. Fixed columns 10 are tightly clamped at both ends inside the reinforcing bars 9, and the sides of the fixed columns 10 close to the U-shaped main board 1 and the side board 2 are respectively bonded to their inner walls.

[0038] In this embodiment: Through the X-shaped reinforcing bars 9 and the fixed columns 10, the effect of lateral support on the U-shaped main board 1 and the side board 2 can be achieved, and the acting force can be shared when subjected to lateral force, effectively improving the lateral strength of the packaging carton.

[0039] Specifically, as Figure 4 shown, both the U-shaped main board 1 and the side board 2 include two kraft paper veneer layers 11. Between the opposite sides of the two kraft paper veneer layers 11, a reinforcing layer 12 and a buffer layer 13 are provided, and the sides of the reinforcing layer 12 and the buffer layer 13 close to the surface and the inner kraft paper veneer layer 11 are bonded to the two respectively.

[0040] Specifically, as Figure 5 shown, the reinforcing layer 12 includes two corrugated cardboard layers 121, and the sides of the corrugated cardboard layers 121 close to the surface kraft paper veneer layer 11 and the buffer layer 13 are bonded to the two respectively. A number of reinforcing column members 122 made of corrugated cardboard are bonded to the opposite sides of the two corrugated cardboard layers 121, and the reinforcing column members 122 are arranged in a grid pattern.

[0041] In this embodiment: Since both the U-shaped main board 1 and the side board 2 are composed of two kraft paper veneer layers 11, a reinforcing layer 12 and a buffer layer 13, and the reinforcing layer 12 is provided with reinforcing column members 122 and corrugated cardboard layers 121 arranged in a grid pattern, the structural strength of the packaging carton during use can be improved. Therefore, the damage to the packaging carton can be reduced, the service life of the packaging carton can be effectively extended, and the environmental friendliness of the recycling use of the packaging carton can be enhanced.

[0042] Working principle: When the packaging carton is in use, the side board 2 can be folded along the crease to approach the U-shaped main board 1, and the connecting block 51 can enter the inside of the connecting groove 6. When the connecting block 51 enters the U-shaped main board 1, the elastic clamping plate 52 will first contact the inner wall of the U-shaped main board 1. Limited by the space, the two elastic clamping plates 52 on the front and rear sides will deform towards the connecting block 51 and compress the positioning spring 53. Therefore, when the connecting block 51 is inside the U-shaped main board 1, due to the elasticity of the elastic clamping plate 52 and the positioning spring 53, the elastic clamping plate 52 can be firmly located inside the U-shaped clamping plate and is not easily disengaged. At the same time, the hook surface 8 of the magic tape is adhered to the loop surface 7 of the magic tape, which can ensure the firmness between the side board 2 and the U-shaped main board 1. When the item needs to be taken out, the two side boards 2 can be directly deflected along the crease. When the applied pulling force is greater than the elasticity of the elastic clamping plate 52 and the positioning spring 53, the connecting block 51 will disengage from the connecting groove 6, separating the two side boards 2 from the U-shaped main board 1, and the item can be exposed to the environment, making it convenient to take out the item. Since both the U-shaped main board 1 and the side board 2 are composed of two kraft paper veneer layers 11, a reinforcing layer 12 and a buffer layer 13, and the reinforcing layer 12 is provided with reinforcing column members 122 and corrugated cardboard layers 121 arranged in a grid pattern, the structural strength of the packaging carton during use can be improved. Therefore, the damage to the packaging carton can be reduced, the service life of the packaging carton can be effectively extended, and the environmental friendliness of the recycling use of the packaging carton can be enhanced.

[0043] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
