Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, and specifically relates to a paper box. Background Technique

[0002] A paper box is a three-dimensional shape, which is composed of a polyhedron formed by the movement, stacking, folding, and surrounding of several component surfaces. At the same time, it is also a packaging and storage tool that is easy to manufacture and widely used.

[0003] For example, a paper box is disclosed in a Chinese patent (publication number: CN213139400U), which includes a bottom plate, several side plates, and a cover plate. Fixed films are adhered to the outer sides of the bottom plate, the cover plate, and each side plate. The fixed films connect the bottom plate, each side plate, and the cover plate to form an integrated setting. The bottom plate is rectangularly arranged. In this embodiment, there are four side plates, and each side plate is vertically arranged on each side edge of the bottom plate. Each side plate and the bottom plate enclose a storage cavity for placing items. The upper end of the storage cavity is open. The cover plate is foldably connected to one of the side plates. After the cover plate is folded downwards, it can cover the open end at the upper end of the storage cavity. A connecting piece for connecting and fixing each side plate is arranged at the connecting end of any two adjacent side plates. This application has the effect of reducing the raw material cost of manufacturing the paper box.

[0004] There are still certain deficiencies in the above-mentioned paper box. A tongue plate is foldably arranged at one end of the cover plate far from the folding position. After the tongue plate is folded, it overlaps on the outer side of the side plate. A first magnetic strip is arranged on the side of the tongue plate that fits the side plate, and a second magnetic strip that adsorbs with the first magnetic strip is arranged on the outer side of the side plate that fits the tongue plate. When the cover plate covers the upper end of the storage cavity, the first magnetic strip on the tongue plate adsorbs and fixes with the second magnetic strip on the side plate, thereby fixing the cover plate. However, the fixation by the magnetic strip is not stable. Once the paper box falls, it is difficult for the magnetic strips to adsorb with other magnetic strips, resulting in the cover plate flipping and the object falling out of the paper box. Therefore, this application proposes a paper box to solve the above problems. Content of the Utility Model

By rotating the threaded rod 402 in the thread holes 401, the moving block 403 is driven to move.

[0033] The limiting component includes a clamping block 405 hinged to the opposite sides of the two hinge rods 404. Card slots 406 are opened on the left and right sides of the inner cavity of the paper box body 1.

[0034] Among them, a rotating handle is fixed on the upper surface of the threaded rod 402 for facilitating the rotation of the threaded rod 402.

[0035] In addition, two sliding rods are fixed between the upper and lower sides of the inner cavity of the cover plate 3. The moving block 403 is slidably connected to the outer surface of the sliding rods, increasing the stability of the moving block 403 during movement and preventing the moving block 403 from rotating with the threaded rod 402.

[0036] Furthermore, the clamping block 405 is slidably connected inside the card slot 406 for installing and fixing the cover plate 3 to prevent the cover plate 3 from moving. A T-shaped block is fixed on the lower surface of the clamping block 405. Two T-shaped grooves are opened on the lower surface of the inner cavity of the cover plate 3. The T-shaped block is slidably connected inside the T-shaped grooves, increasing the stability of the cover plate 3 during movement.

[0037] In the installation mechanism 4 of this embodiment, the cover plate 3 is placed on the two bottom plates 407. The rotary handle is rotated to drive the threaded rod 402 to rotate in the threaded hole 401, driving the moving block 403 to move.
