Description

Technical Field

[0001] This utility model relates to the field of cardboard box technology, specifically a moisture-proof and waterproof high-strength cardboard box. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various sizes and models. Three-layer and five-layer cardboard boxes are commonly used, while seven-layer boxes are less common. Each layer consists of linerboard, corrugated paper, core paper, and facing paper. Linerboard and facing paper can be made of kraft paper or corrugated cardboard, while the core paper is made of corrugated paper. The color and feel of each type of paper differ, and the paper produced by different manufacturers also varies in color and feel. They are typically used as wrapping materials for goods or as the outer protective layer for items.

[0003] Existing cardboard boxes have limited strength and are easily deformed when subjected to external pressure, which can easily damage the items placed inside. To address this, we propose a moisture-proof and waterproof high-strength cardboard box. Utility Model Content

[0004] The purpose of this invention is to provide a moisture-proof and waterproof high-strength cardboard box to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a moisture-proof and waterproof high-strength cardboard box, comprising a cardboard box body, with a sealing seat at the top and bottom of the cardboard box body, the cardboard box body and the sealing seat being connected and fixed by a connecting seat, the cardboard box body being composed of an outer cardboard box layer, an inner cardboard box layer and an inflatable airbag, the inner cardboard box layer being located inside the outer cardboard box layer, and the gap between the inner cardboard box layer and the outer cardboard box layer being divided into several protective buffer cavities by multiple equally spaced support partitions, the outer cardboard box layer, the inner cardboard box layer and the support partitions being an integral structure, the inflatable airbag being arranged in a ring along the inner wall of the inner cardboard box layer, the inflatable airbag being fixed to the inner surface of the inner cardboard box layer, and the inflatable airbag being provided with an inflation port.

[0006] Preferably, the sealing seat is composed of a moisture-proof pad and a connector. The connector is fixed at the center of the surface of the moisture-proof pad. A second connector groove is provided on the side of the connector, which is connected to the connector. The upper and lower sides of the carton body are provided with a first connector groove, which is connected to the connector.

[0007] Preferably, the surface of the connector has a plurality of vent holes 1 that communicate with the connector slot 2 at equal intervals. The connector is a hollow structure. The inside of the connector is filled with a desiccant pack. The top and bottom surfaces of the connector are provided with vent holes 2 at equal intervals. Each side of the surface of the connector has a desiccant pack filling port.

[0008] Preferably, a rotatable locking pin is installed at each of the outer ends of the connecting seat.

[0009] Preferably, a handle is fixed on each of the two outer sides of the carton body.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The main body of the cardboard box of this utility model is composed of an outer cardboard box layer, an inner cardboard box layer, and an inflatable airbag. The gap between the inner cardboard box layer and the outer cardboard box layer is divided into several protective buffer cavities by multiple support partitions arranged at equal intervals. This structure increases the structural strength of the part composed of the outer cardboard box layer and the inner cardboard box layer, and the existence of the protective buffer cavities allows the main body of the cardboard box to play a buffering role when it is squeezed. The inflatable airbag is arranged on the inner wall of the inner cardboard box layer, and the inflatable airbag can play a good buffering role, so that the items placed inside the cardboard box are not easily damaged when the main body of the cardboard box is squeezed.

[0011] The connecting seat of this utility model can be filled with a desiccant pack through the desiccant pack filling port, thereby drying the inside of the carton body. Furthermore, since the connecting seat can be pulled out from the outside of the carton, it is convenient to replace the desiccant pack. Attached Figure Description
