Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically relating to an integrated environmentally friendly cardboard molding inner lining structure. Background Technology

[0002] Environmentally friendly paperboard is a type of paperboard made primarily from renewable resources through environmentally friendly processes. It can be naturally degraded or recycled after use, combining practicality and environmental friendliness. It is widely used in packaging, printing, construction and other fields. The production process reduces or eliminates the use of harmful chemicals, such as using chlorine-free bleaching processes to reduce wastewater pollution.

[0003] Specifically, most environmentally friendly cardboard molding lining structures on the market use splicing to support and fix the inside of the carton. However, this splicing structure has significant strength defects. The splicing relies on the mechanical interlocking between the cardboard or a small amount of environmentally friendly adhesive to connect them. Its tensile and shear resistance is far lower than that of the integral molding structure. When the packaging is subjected to external impact, the splicing seam is prone to cracking or detachment due to stress concentration, which may cause the lining to deform and lose its restraining function for the product, causing the product to shake and collide inside the carton, resulting in scratches or functional damage. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated environmentally friendly cardboard molding liner structure, which aims to solve the problem that most environmentally friendly cardboard molding liner structures on the market use splicing methods to support and fix the inside of the carton. However, this splicing structure has significant strength defects. The splicing relies on the mechanical interlocking between the cardboard or a small amount of environmentally friendly adhesive to connect them. Its tensile and shear resistance is far lower than that of the integrated molding structure. When the packaging is subjected to external impact, the splicing seam is prone to cracking or detachment due to stress concentration, which may lead to deformation of the liner, loss of the restraining function of the product, and cause the product to shake and collide inside the carton, resulting in scratches or functional damage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated environmentally friendly cardboard forming inner lining structure, including a carton shell and an inner lining horizontal plate installed on the inner wall of the carton shell, wherein an inner lining vertical plate is connected to the side of the inner lining horizontal plate, and the contact ends of the inner lining horizontal plate and the inner lining vertical plate with the carton shell are connected with folded corners;

[0006] The inner wall of the carton shell near the corner is connected to a tongue, and a locking block is connected to the side of the corner near the tongue. A locking groove is opened on the side of the tongue near the locking block.

[0007] To facilitate the assembly of the inner lining structure, as a one-piece environmentally friendly cardboard molded inner lining structure of this utility model, preferably, the inner lining horizontal plate, inner lining vertical plate and corner are made as a single piece.

[0008] In order to improve the strength of the inner lining structure, as a one-piece environmentally friendly cardboard molding inner lining structure of this utility model, preferably, the folded corner and the tongue of the inner wall of the carton shell form an interlocking structure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The present invention provides the following technical solution: an integrated environmentally friendly cardboard forming inner lining structure, including a carton shell 1 and an inner lining horizontal plate 2 installed on the inner wall of the carton shell 1, an inner lining vertical plate 3 connected to the side of the inner lining horizontal plate 2, and a folded corner 4 connected to the contact end of the inner lining horizontal plate 2 and the inner lining vertical plate 3 with the carton shell 1. The production process of the inner lining structure reduces or eliminates the use of harmful chemicals, such as using a chlorine-free bleaching process to reduce wastewater pollution.

[0023] The inner wall of the carton shell 1 near the corner 4 is connected to a tongue 5, and a locking block 6 is connected to the side of the corner 4 near the tongue 5. A locking groove 7 is opened on the side of the tongue 5 near the locking block 6.

[0024] Preferably, the inner horizontal lining plate 2, the inner vertical lining plate 3, and the angle 4 are made as a single unit. In practical use, the overall strength is improved by making the inner horizontal lining plate 2, the inner vertical lining plate 3, and the angle 4 as a single unit.

[0025] Preferably, the folded corner 4 and the tongue 5 on the inner wall of the carton shell 1 form a fitting structure. In actual use, by fitting the locking block 6 on the inner side of the folded corner 4 into the locking groove 7 on the inner wall of the tongue 5, the stability of the inner lining horizontal plate 2 and the inner lining vertical plate 3 is ensured.

[0026] Preferably, the locking block 6 on one side of the fold 4 and the locking groove 7 on the inner side of the tongue 5 form an engaging structure. In actual use, by fitting the locking block 6 into the locking groove 7 on the inner side of the tongue 5, it is convenient to support the inner lining horizontal plate 2 and the inner lining vertical plate 3 stably with the carton shell 1.

[0027] Preferably, a reinforcing plate 8 is connected to the bend of the inner lining horizontal plate 2 and the inner lining vertical plate 3, and a butt plate 9 is connected to the bottom end of the reinforcing plate 8.

[0028] Preferably, both the reinforcing plate 8 and the connecting plate 9 are made of PVC. In practical use, the use of the reinforcing plate 8 and the connecting plate 9 enhances the strength of the bending points of the inner lining structure.

[0029] Preferably, the mating plate 9 is connected to the top of the reinforcing plate 8 near the top of the reinforcing plate 8 with a positioning buckle 10, and the inner side of the reinforcing plate 8 near the positioning buckle 10 is provided with a positioning groove 11. In actual use, by engaging the positioning buckle 10 with the inner side of the reinforcing plate 8, it is convenient to install the mating plate 9 and the reinforcing plate 8 stably.

[0030] The working principle of this utility model is as follows: First, the angle 4 of the inner lining horizontal plate 2 and the inner lining vertical plate 3, which are integrally formed, is fitted into the tongue 5 inside the carton shell 1. At this time, the locking block 6 on the inner side of the angle 4 engages with the locking groove 7 inside the tongue 5, thereby supporting the inner lining horizontal plate 2 and the inner lining vertical plate 3 with the carton shell 1. At the same time, the integrally formed inner lining horizontal plate 2 and the inner lining vertical plate 3 further enhance the support strength and improve the performance of the inner lining structure. In addition, by embedding the reinforcing plate 8 at the bend of the inner lining horizontal plate 2 and the inner lining vertical plate 3, the positioning buckle 10 on the surface of the connecting plate 9 is engaged and fixed with the positioning groove 11 on the inner side of the reinforcing plate 8. This facilitates the reinforcement of the bend of the inner lining horizontal plate 2 and the inner lining vertical plate 3, further improving the service life of the inner lining horizontal plate 2 and the inner lining vertical plate 3.
