Description

Technical Field

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

[0002] As the name suggests, a packaging box is a box used to package products. Packaging boxes generally have two functions. One is to package products for easy storage and transportation of products. The other is to be used as a beautiful display and is widely used in life.

[0003] At present, there are many kinds of packaging boxes on the market, but the structural design of most packaging boxes is relatively fixed and the function is single, which cannot meet the diverse usage needs of users, especially for scenarios where multiple small items need to be stored and protected at the same time. There is a lack of a packaging box that is easy to use and can effectively protect the internal items.

[0004] For example, Chinese patent CN220054509U discloses a packaging box, which belongs to the technical field of packaging boxes and includes a box body and a connecting piece. The connecting piece is detachably connected to the box body, and the connecting piece is constructed to be limitedly located inside the box body when connected to the box body. The product utility model provides a packaging box, and the connection between the connecting piece and the box body can effectively improve the firmness of the box body, and the detachable connection method also allows the connecting piece to be separated from the box body according to usage requirements, thereby improving the flexibility of use of the packaging box, and the connecting piece can be reused to avoid waste and is green and environmentally friendly.

[0005] Although the above patent improves the flexibility of using this type of packaging box, and the connectors can be reused to avoid waste and be environmentally friendly, in this patent, the user needs to open the lid to take out or put in items. For scenarios where multiple small items need to be stored at the same time, the user may need to prepare multiple small boxes or bags for classified storage, which is very inconvenient to use. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a packaging box, which has the function of extending and contracting the packaging box through a simple rotation operation, and can store multiple small items at the same time, thereby improving the convenience of use and solving the problem that the user needs to open the lid to take out or put in items. For the scenario where multiple small items need to be stored at the same time, the user may need to prepare multiple small boxes or bags for classified storage, which is very inconvenient to use.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a packaging box, comprising a top plate and a packaging box bottom plate, wherein a connection mechanism is provided on the upper surface of the packaging box bottom plate;

[0008] The connecting mechanism includes a main shaft, four shaft plates, four small boxes, four limit rods, four limit heads and four slide grooves. The bottom end of the main shaft is rotatably connected to the upper surface of the bottom plate of the packaging box, and the top end of the main shaft is fixedly connected to the lower surface of the top plate. The four shaft plates are fixed on the outside of the main shaft and distributed in a rectangular shape. One end of the shaft plate is rotatably connected to one side of the outside of the small box, and the lower surface of the small box fits with the upper surface of the bottom plate of the packaging box.

[0009] By adopting this technical solution, the expansion and contraction functions of the packaging box can be achieved through a simple rotation operation, and multiple small items can be stored at the same time, which improves the convenience of use.

[0010] Furthermore, a rotating handle is fixed on the upper surface of the top plate, an anti-skid rubber tube is fixed on the outer side of the rotating handle, and no less than two anti-skid grooves are formed on the outer side of the anti-skid rubber tube.

[0011] By adopting this technical solution, the top plate and the four shaft plates can be driven to rotate by turning the rotating handle.

[0012] Furthermore, the anti-slip grooves, which are not less than two in number, are evenly distributed on the outer side of the anti-slip rubber layer.

[0013] By adopting this technical solution, the anti-skid performance of the hand-held anti-skid rubber tube can be improved by providing no less than two anti-skid grooves.

[0014] Furthermore, the inner diameter of the anti-slip rubber tube is matched with the outer diameter of the rotating handle.

[0015] By adopting this technical solution, the stability of rotating the handle can be improved through the anti-slip rubber tube.

[0016] Furthermore, the four slide grooves are all opened on the lower surfaces of the four small boxes, one ends of the four limit rods are fixed at the four corners of the upper surface of the bottom plate of the packaging box, the limit head is fixed on the top of the limit rod, the limit rod is slidably connected to the inside of the slide groove, and the limit head is located on the upper side of the slide groove.

[0017] By adopting this technical solution, when the four small boxes are extended and contracted, the four limit rods slide inside the four slide grooves.

[0018] Furthermore, the upper surfaces of the four small boxes are all in contact with the lower surface of the top plate.

[0019] By adopting this technical solution, four small boxes can be used to store multiple small items, thereby improving the convenience of use.

[0020] Furthermore, the rotating handle is located on the longitudinal center axis of the top plate.

[0021] By adopting this technical solution, the top plate can be rotated by the handle.

[0022] Furthermore, the small box is in the shape of a rectangular body with a hollow interior and a missing top, and the top plate and the bottom plate of the packaging box are equal in size.

[0023] By adopting this technical solution, objects can be stored in four small boxes.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] When the packaging box needs to be unfolded, the outer side of the anti-skid rubber tube is held and the rotating handle is rotated. The anti-skid rubber tube has anti-skid performance, and then the top plate is driven to rotate and the main shaft is driven to rotate, and then the four axis plates can be driven to rotate, so that the four small boxes are extended, which is convenient for placing objects. A sliding groove is opened on the lower surface of each small box, and limiting rods are fixed at the four corners of the upper surface of the bottom plate of the packaging box. One end of the limiting rod extends into the sliding groove and can slide in the sliding groove. Through the mutual cooperation of the four sliding grooves and the four limiting rods, the four small boxes can be limited to move according to the specified trajectory. When shrinking at the same time, the rotating handle can be rotated, and then the four small boxes can be shrunk through the mutual cooperation between the main shaft, the four axis plates, the four limiting rods and the four sliding grooves. The extension and contraction functions of the packaging box can be realized through simple rotation operation, and multiple small items can be stored at the same time, which improves the convenience of use.
