Refrigerator built-in plastic packaging box with adjustable containing cavity

Abstract

The invention discloses a refrigerator built-in plastic packaging box with an adjustable containing cavity. The refrigerator built-in plastic packaging box comprises a packaging box body, the edge ofthe upper end of the packaging box is provided with a boss edge in an integral injection molding mode, a detachable fastener part is connected to the boss edge, a partition plate is arranged in the middle of the packaging box body, built-in grooves are formed in the front side surface and the rear side surface of the partition plate, at least one rotary storage mechanism is arranged in each built-in groove, each rotary type storage mechanism comprises a rotary shaft, a telescopic storage assembly and a positioning piece, the top ends of the telescopic storage assemblies are fixedly connected to the rotary shafts in a sleeve mode, the rotary shafts are arranged along the length direction of the built-in grooves, the rotating shafts are arranged in parallel with the partition plate, and locking pieces corresponding to the positioning pieces are further arranged on the outer side surface of the packaging box body. According to the plastic packaging box, the structural design is reasonable, the function is diverse, the storage space in the plastic packaging box can be freely switched, so that the phenomenon that cold air is scattered during the frequent refrigerator opening and objecttaking process is avoided, and the practicability is high.

Description

technical field [0001] The invention relates to a refrigerator built-in plastic packaging box with an adjustable volume cavity. Background technique [0002] Due to its low cost, easy manufacture, and good moisture-proof and waterproof performance, plastic packaging boxes have a wide range of applications, especially when storing food in refrigerators. However, the existing packaging boxes The structure is simple and the function is single, especially when it is necessary to store objects of different sizes, it cannot be flexibly adjusted, which limits the use of existing plastic storage boxes, such as vegetables, eggs, and meat, because they occupy different positions in the refrigerator. volume, so the existing plastic packaging box can not meet the purpose of its classified storage. [0003] Secondly, in the refrigerator, items are usually separated by horizontal built-in panels, which tends to cause cold air to escape when the refrigerator is frequently opened, and is a...

Problems solved by technology

[0002] Due to its low cost, easy manufacture, and good moisture-proof and waterproof performance, plastic packaging boxes have a wide range of applications, especially when storing food in refrigerators. However, the existing packaging boxes The structure is simple and the function is single, especially when it is necessary to store objects of different sizes, it cannot be flexibly adjusted, which limits the use of existing plastic storage boxes, such as vegetables, eggs, and meat, because they occupy different positions in the refrigerator. volume, so the existing plastic packaging box can not meet the purpose of its classified storage

[0003] Secondly, in the refrigerator, the items are usually separated by the built-in board arranged horizontally, which will easily cause the cold air to escape when the refrigerator is opened frequently, and it is not conducive to keeping the temperature of the items in the refrigerator for a long time.
