Foldable Cooler

Abstract

The present invention discloses a foldable cold insulation box comprising a bottom frame, a pair of first side walls, a pair of second side walls, a plurality of pivot pieces, and a cover. The bottom frame has a bottom plate and a pair of first connection side walls and a pair of second connection side walls extending from the bottom plate. At least one first rotary shaft and at least one second rotary shaft are respectively formed on the bottom side of the first side walls and the second side walls. Each pivot member has a pivot portion and fixed portions, wherein the pivot portion is pivoted to both ends of the first and second rotary shafts, and the fixed portions are connected to the inside of the first and second connection side walls, thereby achieving pivot joints between the bottom frame and the first and second side walls. The cover is coupled to the top side of the first and second side walls to close the foldable cold box.

Description

technical field [0001] The invention relates to a foldable cold storage box; in particular, it relates to a foldable cold storage box with improved heat insulation effect. Background technique [0002] The foldable cold box is used to put in, store or transport various items that need to be kept warm or kept fresh. Foldable cold storage boxes are widely used in low temperature delivery applications because they can reduce the volume without putting them in, and can reduce transportation costs or storage costs when they are not in use. [0003] However, gaps in the gas passage are easily formed at the folded part of the existing foldable cold storage box, resulting in poor heat insulation effect, and the structure of the folded part is generally complicated, resulting in high manufacturing cost. Contents of the invention [0004] In view of the above-mentioned existing problems, an object of the present invention is to provide a foldable cold storage box, the structure of ...
