AI Technical Summary

Technical Problem

When the depth of a cardboard box is much greater than the height of the item, it is difficult for users to put or take the item in. Furthermore, when the size of the item is close to the inner cavity of the cardboard box, it is easy for the item to get stuck or shake when there is a reserved gap, resulting in cumbersome operation or damage to the item.

Method used

Design a carton structure with a lid that lifts upon opening, including a rotatably connected carton body and lid, and a lifting assembly. Through the rotatable connection of a lifting plate, an upper connecting plate, and a lower connecting plate, the lifting plate is driven to automatically lift the items when the lid is opened, preventing fingers from reaching into the bottom of the carton or the carton from tipping over.

Benefits of technology

It enables convenient retrieval and placement of items, avoids damage to items, solves the difficulties and jamming issues in retrieving items from deep boxes, and improves the convenience and safety of operation.

Abstract

This utility model provides a carton structure with a lifting mechanism for opening the lid, including a carton body and a lid rotatably connected between open and closed states, and several lifting components. Each lifting component includes a lifting plate, an upper connecting plate, and a lower connecting plate connected to the end of the lifting plate. One end of the upper connecting plate is rotatably connected to the lifting plate, and the other end is rotatably connected to the lid. One end of the lower connecting plate is rotatably connected to the lifting plate, and the other end is rotatably connected to the carton body. The connection points between the lifting plate, the upper connecting plate, and the lower connecting plate constitute a rotating part. When the carton switches from a closed state to an open state, the upper and lower connecting plates pull the rotating part towards the rear end of the carton body and drive the lifting plate to move away from the bottom of the carton body. When the lid is opened, the lifting plate automatically lifts and raises the contents of the carton, eliminating the need for the user to reach their fingers into the bottom of the carton or tilt the carton, thus solving the problem of difficulty in retrieving items from deep cartons.
