Technical Field

[0001] The utility model relates to the field of moisture-proof carton, in particular to a bottom moisture-proof structure of a packaging carton. Background Art

[0002] Cartons are widely used packaging products and are widely used in daily life and industrial production. Cartons can be used to transport items as well as to store items. There are many types of cartons with different functions. The functions vary according to the size of the cartons. However, these cartons have certain shortcomings when used. If the cartons are placed on the ground for a long time, the paper box body will come into contact with the bottom surface, and the moisture and humidity on the ground will enter the box body through the cardboard, causing the items stored in the carton body to get damp, affecting the quality of the stored items, reducing the storage effect of the carton, and making it inconvenient to use. Therefore, we propose a bottom moisture-proof structure for packaging cartons. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0022] like Figures 1 to 6 The bottom moisture-proof structure of a packaging carton shown in the figure comprises a carrying plate 1, the carrying plate 1 is connected with a supporting frame 7 and a placing frame 8, the placing frame 8 and the supporting frame 7 are respectively provided with air vents 9, a desiccant bag 10 is connected to the inner side of the placing frame 8, the desiccant bag 10 can be directly placed in the placing frame 8 for easy placement, the carrying plate 1 is provided with a sliding groove 2, an extension plate 3 is slidably connected to the inner side of the sliding groove 2, the extension plate 3 is connected to a contact plate 4, the contact plate 4 is located on the outer side of the carrying plate 1, a positioning groove 12 is provided on the side wall of the sliding groove 2, a positioning plate 11 is slidably connected to the inner side of the positioning groove 12, a threaded rod 13 is threadedly connected to the carrying plate 1, and the threaded rod 13 is connected to the positioning plate 11; four groups of sliding plates and contact plates 4 are provided, the four groups of contact plates 4 are respectively located on the front, back, left and right sides of the carrying plate 1, the contact plates 4 cooperate with the sliding plates one by one, the sliding plates on the left and right sides are not on the same horizontal plane as the sliding plates on the front and back sides, which is convenient for structural layout and does not affect each other.

[0023] The threaded rod 13 is rotatably connected to the positioning plate 11, and the positioning plate 11 abuts against the side wall of the positioning groove 12. The side wall of the positioning groove 12 can limit the rotation of the positioning plate 11. The threaded rod 13 is provided with a socket 14.
