Description

Technical Field

[0001] The utility model relates to the field of apple packaging, in particular to a packaging box for packaging apples. Background Art

[0002] Apple is a nutritious fruit that is rich in vitamin C, vitamin K, fiber and various minerals. Eating apples helps maintain heart health. Apples are usually stored in boxes to prevent them from coming into contact with the external environment and reduce contamination by bacteria and microorganisms, thereby improving food hygiene standards and reducing food safety risks.

[0003] At present, in the process of storing apples, since the positions of the air holes on the packaging box are fixed, the apples close to the air holes have better ventilation, while the apples far from the air holes have poorer ventilation, resulting in a higher ethylene concentration on the surface of some apples, thereby accelerating the decay speed of some apples and further reducing the freshness of some apples. Therefore, the utility model proposes a packaging box for packaging apples. Utility Model Content

[0004] The purpose of the utility model is to provide a packaging box for packaging apples to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a packaging box for packaging apples, comprising a box body, a sealing cover is fixedly connected to the top of the box body, and vertical plates are fixedly connected to both sides of the box body;

[0006] Two rotating rods are rotatably connected to the sides of the two vertical boards, and a cross is fixedly connected to the ends of the rotating rods away from the vertical boards. Four placement frames are rotatably connected between the two crosses, and the ends of the rotating rods away from the crosses penetrate the side walls of the vertical boards and are provided with inner flat grooves;

[0007] There are two slides slidably connected between the vertical plate and the box body, and a limiting convex strip matched with the inner flat groove is fixedly connected to the side of the slide close to the rotating rod, and the limiting convex strip is slidably connected to the inner flat groove, and a pair of gear rings are fixedly connected to the outer side wall of the rotating rod, and a pair of racks matched with the gear ring are fixedly connected to the side of the slide close to the gear ring.

[0008] Preferably, one end of the slide plate passes through the side wall of the box body and is fixedly connected to a pull rod.

[0009] Preferably, a rubber sleeve is fixedly connected to the outer side wall of the pull rod.

[0010] Preferably, a pair of stabilizing rods are fixedly connected to both sides of the placement frame, two special-shaped grooves are provided on the adjacent sides of the two vertical plates, and the stabilizing rods are slidably connected inside the special-shaped grooves.

[0011] Preferably, a slip ring is rotatably connected to the outer side wall of the stabilizing rod, and the stabilizing rod is slidably connected to the special-shaped groove through the slip ring.

[0012] Preferably, a plurality of partitions are fixedly connected to the inner side walls of the placement frame.

[0013] Preferably, a T-shaped block is fixedly connected to one side of the slide plate away from the rotating rod, two pairs of limiting strips are fixedly connected between the vertical plate and the box body, and the slide plate is slidably connected to the limiting strips through the T-shaped block.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] In the utility model, the slide plate and the limiting convex strip are driven to slide along the limiting long strip by pulling the pull rod, so that the limiting convex strip is separated from the inner flat groove, and the limiting of the rotating rod is released. Under the meshing action of the rack and the gear ring, the slide plate drives the rotating rod to rotate, and the rotating rod drives the four placement frames to rotate through the cross. Under the limiting action of the stabilizing rod and the special-shaped groove, the frame opening direction of the placement frame is always kept vertically upward. After the rotating rod drives the four placement frames to rotate 180 degrees through the cross, the positions of the apples close to the air vents and the apples far from the air vents are exchanged. By regularly adjusting the position of the apples in the box body, the ethylene concentration on the surface of some apples is prevented from being always high, thereby slowing down the decay rate of the apples and further improving the freshness of the apples.
