Description

Technical Field

[0001] This utility model relates to the field of packaging carton technology, specifically a packaging carton with a lifting structure. Background Technology

[0002] Packaging cartons are made of paper products and are used to package various items. They are divided into single-wall (3-ply), double-wall (5-ply), triple-wall (7-ply), and quadruple-wall (9-ply) cartons. Cartons are further subdivided into paper boxes, color boxes, color cartons, and extra-large, oddly shaped die-cut boxes, etc.

[0003] The current packaging cartons, being a single-piece structure, require both hands to handle during transport, making them cumbersome and affecting ease of use. Furthermore, the external connecting straps hinder the packaging and installation of the cartons, and placing them directly on the ground exposes them to water, causing them to become wet. Utility Model Content

[0004] The purpose of this utility model is to provide a packaging carton with a lifting structure to solve the problems mentioned in the background art. These problems include the fact that current packaging cartons, being simple cartons, require two hands to handle during transport, making them cumbersome and affecting ease of use; the external connecting straps hindering the use of the carton and making it difficult to install; and the risk of the carton getting wet if placed directly on the ground.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A packaging carton with a lifting structure includes a main carton body. Plastic pads are evenly joined to the bottom surface of the main carton body. A top opening is horizontally formed on the top surface of the main carton body. A sealing cover is horizontally and symmetrically fixed to the inner side of the top opening. A top mating groove is symmetrically formed on the top surface of the main carton body. A sealing cardboard is horizontally connected to the inner side of the top mating groove. Bottom locking holes are symmetrically formed on the bottom surface of the main carton body. A locking post is fixedly set on the top surface of the plastic pads. A vertical channel is vertically formed on the inner bottom surface of the top mating groove. A mating bottom groove is formed at the inner bottom end of the vertical channel. A pulling spring is vertically locked to the inner side of the mating bottom groove. A locking plastic plate is horizontally locked to the inner side of the vertical channel. A connecting strap is fixedly connected to the top surface of the locking plastic plate. A handle is horizontally locked to the inner side of the top mating groove.

[0007] In a preferred embodiment of this utility model, there are four plastic pads, all of which are made of rigid plastic material. The top surfaces of the four plastic pads are aligned and connected to the bottom opening of the bottom card hole, and the top opening is opened through the center of the top surface of the main carton.

[0008] In a preferred embodiment of this utility model: there are two sealing cover plates, and the two sealing cover plates are horizontally symmetrically arranged on the inner side of the top opening. One side of the sealing cover plate is flipped and folded and connected to the inner side of the top opening. There are two top mating grooves, and the two top mating grooves are symmetrically opened on the top surface of the main carton body near both ends of the center line.

[0009] In a preferred embodiment of this utility model: the sealing cardboard edge is connected to the inner top opening of the top mating groove, the bottom card holes are symmetrically opened on the bottom surface of the main carton near the four corners, and the top of the carding column is fixedly inserted into the inner side of the bottom card hole.

[0010] As a preferred embodiment of the present invention: there are four vertical channels, and the four vertical channels are arranged in pairs in parallel and symmetrical arrangement at both ends of the bottom surface of the top mating groove. The interior of the mating bottom groove is connected to the interior of the vertical channels. The top end of the pulling spring extends to the inner side of the vertical channel, and the extended top end is fixedly connected to the center of the bottom surface of the snap-fit ​​plastic plate.

[0011] In a preferred embodiment of this utility model: the snap-fit ​​plastic plate is made of rigid plastic material, the top end of the connecting strip extends to the inner side of the top mating groove, and the extended top end is fixedly connected to both ends of the handle rod body. The handle rod body is made of hard rubber material, and the top surface of the handle rod body is horizontally mated to the bottom surface of the sealing cardboard.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses four plastic pads fixedly connected to the bottom locking holes via snap-fit ​​posts on the top surface. When the main carton is placed in the designated position, the plastic pads on the bottom surface create an isolation from the ground, preventing the bottom of the main carton from coming into contact with water stains and thus avoiding wetting. After the material is placed inside the main carton, the sealing cover on the top opening is flipped to seal it. However, when lifting and carrying the main carton, the two sealing cardboard pieces on the top surface are torn open, and a handle is pulled out from inside the top mating groove and moved upwards. The movement causes the handle to extend upwards along the connecting strap from the vertical channel, allowing the bottom locking plastic plate to move downwards and lock into place at the top opening of the vertical channel. Holding both handles with one hand allows for lifting and carrying the main carton. Releasing the hand causes the bottom spring to retract, pulling the locking plastic plate downwards and retracting the connecting strap into the vertical channel. The integrated structure ensures uninterrupted use, while the concealed storage pull strap makes it even more convenient to use, and the retracted design does not affect the carton's usability.
